The system consists of three main components, namely the heating system, cooler, and drive to position the prototype following the direction of motion of the sun. With a greenhouse effect concept, the heating system at the top keeps the temperature in the acrylic room warm. The hot side of the Peltier is placed with an aluminum plate and andesite stone as heat conductors and storage. The cooling system uses a metal-wrapped fluid as a source of cold temperature equipped with temperaturereducing aluminum foil and nitrogen gas to keep the fluid at a low temperature. Finally, the drive system uses a hydraulic to move the design module following the direction of motion of the sun, whose light will be focused by a convex lens to concentrate. The Peltier is assembled in series and step-up to increase the output voltage to produce maximum results. This prototype design can hopefully contribute to the development of renewable energy.

Therefore, electricity is also going up due to the energy demand of the building. The air conditioning system is the enormous energy consumption in high buildings. The green building concept has been introduced regarding the energy efficiency of a high-rise building. This study investigated the energy consumption in a high building (47 floors) using the load optimization method for the chiller system. The load optimization was conducted by configuring five chillers systems consisting of integral compressors, cooling towers, and pumps. This study obtained the decreasing energy consumption by the chiller's operation load sequencing based on 24-hour data optimization. Optimized chiller performance satisfied the green building standards. However, load optimization on high buildings is highly recommended as an effective way to achieve green building status. Further research is recommended for implementing such optimization at other facilities, such as industrial plants, hospitals, airports, and manufacturing plants.

One of the promising mechanisms to deploy renewable energy is through a Virtual Power Plant (VPP), which can integrate various distributed renewable energy resources into a single controllable and deployable entity. This paper examines the opportunity for VPP adoption in Indonesia, which investigates the minimum implementation criteria, provides a gap analysis for VPP implementation, and proposes recommendations for VPP implementation in Indonesia. The implementation criteria are obtained from the literature review, including the lessons learned from other countries, and categorized into four aspects: regulatory, technical, economic, and social. The gap analysis is performed by evaluating the current state of Indonesia’s utility network in correlation with the VPP minimum implementation criteria and then provides a scoring matrix for each criterion. Lastly, the recommendations are arranged to narrow these gaps, organized into ten key focus points, and divided into four phases:, initiation, preparation, piloting, and deployment, across a ten-year timeframe.

However, the economy of the Battery Energy Storage System (BESS) application is not linear to the cost reduction obtained from excluding the costly generators. This paper presents the economic analysis of cost-based load shifting implementation and an approach to determine the generation units to be deactivated and replaced by BESS on three large-scale power grids in Indonesia: Sumbagut, Sumbagteng, and Sumbagsel systems. The economic feasibility is evaluated using the Net Present Value (NPV), considering the savings and the BESS investment cost. The result shows that the proposed approach is more robust than the conventional methods, such as removing the most expensive units, units with the highest cost reduction, units with the best economic return contribution, or the maximum number of units that can be replaced.

Its effect on ash-related problem was investigated using drop tube furnace combustion test and ash particle observation method. AUS coal (low-slagging risk sample) and KT coal (high-slagging risk sample) were used to obtain AK-1 coal and AK-2 coal. AK-1 coal was a coal sample of out-furnace blending method, while AK-2 coal was coal sample of sequential feeding method. AK-1 probe tended to be more similar to AUS coal with only a small spot of ash attached on the probe surface. Meanwhile, AK-2 probe had more ash attached on the probe surface, indicating more severe slagging than AK-1 probe. According to ash morphology, the result indicated that the upper layer of slag tended to be more similar to AUS coal ash, while initial layer of slag of AK-2 coal contained more KT coal ash. Based on ash mineralogy, sodium in AK-2 coal was distributed evenly which was different with AK-1 coal. This result shows that sequential feeding method is not applicable to reduce slagging and fouling risk of KT coal.

PLN) has aimed to increase the level of electrification to provide a better life for citizens. However, the dispersion of citizens in remote islands challenges the electrification infrastructure and services. Nevertheless, some strategies have been implemented to pass the challenges, including the adoption of the emerging technology smart grid. The smart grid is adopted to solve specific problems of electrical power services for small remote islands with limited energy resources. Although various problems challenge development, smart grid development should follow its comprehensive aims. Therefore, an assessment method is needed to evaluate the smart grid to expose the advantages and disadvantages of the existing design. Furthermore, based on the evaluation results, recommendations can be delivered to increase the performance of the smart grid. Furthermore, the evaluation and recommendations can be used to improve the design of the next smart grid project. Finally, a smart grid on the remote island of Semau is used for a case study.

There are two main functions of battery storage on grid; load shifting and load smoothing. The utilization of battery storage does not only create some technical beneficial such as reliability and flexibility but also a financial cost saving. This study investigates the implementation of lithiumion battery storage system at PV floating farm for reducing the electricity cost production on the grid system. The financial feasibility is conducted through a spread sheet financial modelling based on life cycle cost and levelized cost of electricity. The impact of PV floating with BESS to the grid is tested by a power system tool ETAP. This study found that the implementation of BESS at PV floating farm is potentially reducing the electricity cost production based on both full store and partial store scenarios. The difference of financial cost saving between both scenarios is not significant. Other finding is the implementation of BESS with PV floating does not affect significantly the grid system stability. The result of the study is useful for energy developer and buyer or off taker to define the right cost of power purchasing agreement for battery energy storage system application. It also supports the utility firms that want to utilize the storage technology for achieving more flexible, reliable and resilient of their grid. Further research is recommended to study a capacity optimization of battery storage to the PV farm, to investigate more unit analysis, to asses' various capacity of battery and to analyze it at different grid system

This study aims to investigate the technical and economic aspects of co-firing by conducting a pilot project of three PC boiler plants and capturing several preliminary figures before being implemented for the entire plants in Indonesia. Various measured variables, such as plant efficiency, furnace exit gas temperature (FEGT), fuel characteristic, generating cost (GC), and flue gas emissions, were identified and compared between coal-firing and 5%-biomass co-firing. The result from three different capacities of CFPP shows that co-firing impacts the efficiency of the plant corresponding to biomass heating value linearly and has an insignificant impact on FEGT. Regarding environmental impact, co-firing has a high potential to reduce SO2 and NOx emissions depending on the sulfur and nitrogen content of biomass. SO2 emission decreases by a maximum of 34% and a minimum of 1.88%. While according to economic evaluation, the average electricity GC increases by about 0.25 USD cent/kWh due to biomass price per unit of energy is higher than coal by 0.64×10-3 USD cent/kcal. The accumulation in the one-year operation of 5%-biomass co-firing with a 70% capacity factor produced 285,676 MWh of green energy, equal to 323,749 tCO2e and 143,474 USD of carbon credit. The biomass prices sensitivity analysis found that the fuel price per unit of energy between biomass and coal was the significant parameter to the GC changes.

Some small-isolated islands do not have electricity access supplied by PLN (Indonesia Electricity Company). One of them is Selayar in South Sulawesi which cannot be reached by PLN due to terrain conditions where it is impossible to build the electricity distribution lines. This study aims to determine the potential of renewable energy sources that allow them to be used as electrical energy and reduce the shortage of electrical energy in the Selayar islands. The case studies were performed using HOMER software with various scenarios were investigated between solar, wind, and biomass. The lowest Levelized Cost of Electricity value is obtained for biomass and hybrid Solar-biomass, which are IDR1.496/kWh and IDR1.468/kWh. Between the two technologies, biomass is a technology that can be calculated both in terms of potential and price. In addition, Selayar islands can produce coconut around 21.170 tons/year. To support the government program called REBED (Renewable Energy Based Economic Development), briquettes can not only be used as a source of electrical energy but also can have an impact on the economy of the local community. By forming a briquette business unit, residents have job options and other abilities.

Flat tariff on electricity costumers causes the cost of electricity to be less optimal. In Indonesia, the second highest costumer group after industry is residential customer, who has 37,6 % of total electrical energy consumption. So naturally the load curve tends to approach the curve of residential needs. In the Java Madura Bali system, the peak load of a residential customer occurs at the same time as the peak load on the system. If load shifting scheme of the electrical energy consumption of the residential customer can be applied, it will give a big impact on the system. The peak load is borne by the power plants which generally have expensive operational costs. By the reduction of peak load using load shifting scheme, a significant increase of system efficiency will be obtained. This paper develops a method of determination of a dynamic tariff combination scheme, Time of Use (TOU) and Critical Peak Pricing (CPP) based on revenue neutrality. The scheme is simulated to residential customers in the Java Bali Madura system. From several scenarios, the results of the implementation of this scheme show the increasing of the total cost efficiency of electricity supply in the Java Madura Bali system.

This study aims to clarify the current vague details of Solar LCOE in Indonesia. Moreover, projection of Solar LCOE in Indonesia is calculated from 2020 to 2050, covering aspects such as cost, system configuration with and without batteries, location, and effectiveness of different panel types. Based on NREL and SunPower LCOE formulas as well as data from recent market data and onsite survey. Models of On-Grid Silicon-based Solar Panel System without batteries (Model A) and with battery capacities (1x, 1.5x) of PV module as well as an identical Off-Grid system (Model B) with battery capacities (2.5x, 3x) of PV module are described. The study shows that the LCOE of Model A with 10% discount rate in 2020 will reach grid parity at year 2050 with a predicted rate of IDR 547/kWh, meanwhile until the year 2030, LCOE of Model B with a discount rate of 10% will not reach grid parity. Overall, it can be concluded that an offgrid system will still be too expensive for the commercial market, while the on-grid system with a discount rate of 10% will be viable to use by 2020. The results of the implementation of this scheme show increasing of the total cost efficiency of electricity supply in the Java Madura Bali system.

In this work, a real case study in Nusa Penida Island, Bali Province, Indonesia, is conducted for studying the optimal sizing and performance assessment of a hybrid diesel-PV-BESS system limited by a Take-or-Pay contract of Power Purchase Agreement (PPA). The island's solar irradiance is 5,36 kWh/m 2 /day and 7 x 1.7 MW diesel power plant stations are currently run for fulfilling the island's electricity demand. The stations are embedded into an existing 20 kV distribution grid. Using the electricity demand projection of several representative days in a year, HOMER software is utilized in this work for designing and optimizing the size of PV and BESS integrated to the diesel power generators. In this study, the performance of configurations with four different sizes of PV and BESS are assessed using load flow analysis, short circuit analysis and transient stability analysis. The simulation results demonstrate that the optimal sizing of the hybrid system consists of 10 MWp PV and 10 MWh BESS with Levelized Cost of Energy of 9.45 cents USD/kWh. It lowers 40% of the current cost. Considering the initial, maintenance, replacement and fuel costs, the net present cost of the optimal configuration is 135,306,800 USD. This study confirms that the renewable energy penetration in remote and rural islands can be increased by optimally utilizing energy storage.

Continuity of power transmission is important to ensure the reliability of the electricity supply... more Continuity of power transmission is important to ensure the reliability of the electricity supply. As most system faults are temporary, the auto reclose (AR) scheme has been used extensively to minimise the outage duration, prevent widespread outages, thus increase system stability. Meanwhile, the hybrid transmission line (HTL) combining overhead line (OHL) and high voltage cable has been introduced to provide an inexpensive solution for an urban power grid. Protecting HTL with a conventional protection system would forbid the operation of the AR scheme due to difficulty to ensure whether the fault occurred on the OHL or cable section. Therefore, the circulating current protection (CCP) scheme is used in the cable section to ensure the fault location and block the AR scheme. The technology of an optical current transformer (OCT) as one of the non-conventional instrument transformers (NCIT) has emerged to provide a solution to drawbacks on the conventional current transformer (CCT). Consequently, this paper investigated the impact of using OCT over the CCT for CCP of the HTL. The result shows that OCT could be used for CCP on much longer cable sections thus increase its reliability as the AR scheme can be used on longer or multiple cable section.

In power system network, BESS has ability to do a quick response for regulating the grid frequency caused by some interferences. For dealing with such interferences the utilities have applied a defiance scheme mechanism to prevent the gird blackout due to a rapid change of the frequency for a while. This study investigates the role of Battery Energy Storage System as a frequency controller combining with the defense scheme at the high voltage network. Some defense Scheme indicators within Battery Energy Storage System at a substation has been assessed through a software modelling. The results show that Battery Energy Storage System at Substation is able to increase the reliability of grid by such frequency regulation.

Eleven (11) financing schemes, composed through the combination of Viability Gap Fund (VGF), international grant, tax incentives, and low loan interest, are studied. The electricity tariff resulted from each financing scheme is analyzed and compared to the applicable feed-in tariff to find the optimum financing scheme. Moreover, this paper also includes two types of PV modules, such as thin-film and monocrystalline. The result shows that the funding combination consists of 50% of capital expenditure (CAPEX) from VGF provided by the Government of Indonesia (GoI), 30% of CAPEX provided by the international grant, and 5% of loan interest results in the optimum financing scheme. The resulting electricity tariffs from this financing scheme are 571.04 IDR/kWh and 761.76 IDR/kWh for thin-film and monocrystalline PV plants, respectively, which is below the lowest existing feed-in tariff (985 IDR/kWh).

On the other hand, the expected economic growths together with export obligation led to a demand of natural gas which cannot be met by the local market. Therefore considering the abundant of low rank coal (LRC) availability in domestic market, and the status of coal gasification technology, utilization LRC to be synthetic natural gas (SNG) is highly recommended. This study investigates the feasibility of SNG technically and financially by analyzing the pattern, trend and projection of the national energy, and further examining a scenario to utilize LRC to be SNG. This study found that LRC is mostly feasible converted to be SNG. The proposed gasification is " dry feed entrained flow " technology which can utilize low rank coal as low as 3,500 kcal/kg. The possible SNG options are three scenarios; transport through the existing gas pipeline, in form of CNG and supplied through the existing LNG terminal. The financial analysis shows that SNG is competitive with natural gas if the gas price is above $11/MMBTU and the project IRR is approximately 16.6%. SNG is a viable alternative " new energy " of natural gas which can replace fuel oil for some purposes. It can enhance natural gas supply securilty by diversifying natural gas availibility with " new energy " substitution from abundant cheap LRC, and indeed, strengthen the national energy resilience.

This study found that Solar Power is highly potential to replace diesel power station at " on grid system " (without battery) and " the day time-off grid system " (stand alone PV which operate during day time within battery as a buffer) in all areas. Solar Power is probably feasible to compete with diesel at " 24 hours off grid system " (stand alone PV within sufficient module and battery capacity) at some areas in Indonesia. However PV is not recommended for " 24 hours Off Grid " at locations which have irradiant less than 5 kWh/m 2 /day (or 5 hours of Equal Sun Hour). Other finding is that the cause of low production output (kWh) is solvable matters regardless the balance score card of the existing PV is still low. In addition for reducing CO2 emission generated by fossil fuel distributed power generation, the development of Solar Power is highly recommended.

This study investigated antecedent of technology adoption by connecting TOE with Dynamic capability factors. The four determinant factors has been identified are externalities, entrepreneurial leadership, slack resources, and absorptive capability. Using 518 respondents representing 222 business unit of Indonesia Electricity Company, the study found that only absorptive capability has positively significance effect to technology adoption. The study also empirically proved that technology adoption is a functional competence/capability which mediates dynamic capabilities to firm's performance. Practically regardless firms need some supporting " hardware " content such as externalities, resources and leadership, a successful technology adoption in firm can't be achieved without excellent " software " capability like absorptive capability. Other finding is the absorptive capability typology organization mapping the eight technology adoption status in organization based on those three determinant factors; externalities, entrepreneurial leadership and slack resources.

Keunikannya justru muncul dari unsur keberagamannya ini sehingga lebih memperkaya kajian di bidang inovasi disruptif. Namun tentunya kajian ini masih memiliki limitasi yang beragam dan tidak dirancang untuk memberikan kesimpulan secara sempurna. Meskipun kami mencoba meramu semua tulisan ini agar mudah dan enak dibaca tetapi variasi gaya penulisan, jenis tulisan dan latar belakang penulisnya cenderung membentuk buku ini sebagai bunga rampai dalam arti harafiahnya, yakni layaknya sebuah hidangan campur sari atau “gado-gado” pengetahuan. Suatu kesengajaan jika masing-masing tulisan memang kami sajikan apa adanya.

Perusahaan seperti WalMart, Dell, Google, Facebook, Uber, Apple, Netflix telah membuktikanya. Namun keberhasilan tersebut sebenarnya tidak terjadi begitu saja. Riset yang kami lakukan membuktikan bahwa
faktor eskternal (externalities), kepemimpinan kewirausahaan (entrepreneurial leadership), kesiapan sumber daya (resources readiness), dan kemampuan serap (absorptive capability) menjadi penentu keberhasilan. Kemampuan serap menjadi faktor terpenting karena memediasi pengaruh ketiga faktor lainnya terhadap keberhasilan adopsi teknologi. Tanpa kemampuan serap yang memadai untuk mengelola sumber daya, apalagi dalam kondisi lingkungan yang turbulen, keunggulan bersaing perusahaan tidak akan tercipta sehingga adopsi teknologi menjadi tidak efektif. Riset juga menghasilkan tipologi adopsi teknologi dalam suatu perusahaan dapat dipetakan menjadi delapan status; optimal, inovatif, transaksional, organisasional, transformasional, entrepreneurial, slack dan pasif. Tipologi ini berguna sebagai panduan untuk menentukan strategi yang efektif agar adopsi teknologi betul-betul berhasil mendongkrak kinerja perusahaan.

The four determinant factors have been identified are externalities, entrepreneurial leadership, resources readiness, and absorptive capability. Using an empirical research at utility industry this study found that there is positively significance relation among the determinant factors, and the technology adoption is proven for a mediating factor of dynamic capability to the firm performance. It shows the three path ways of technology adoption for improving firm’s performance. However all those ways show that only absorptive capability - as a dynamic capability at firm level - has direct significant effect to technology adoption. Hence the successful technology adoption in firm can be only achieved by excellent absorptive capability with supporting from other three determinant factors. Without such dynamic capability for managing the resource, technology adoption will be less effective and does not enhance firm’s performance. This book also proposes a 3D technology adoption organization matrix explaining eight levels of technology adoption in firm (organization).

Perkembangan Blue Energy secara global juga lambat, di tahun 2022 kapasitas total Tidal Stream 39,6 MW dan Wave Energy 24,7 MW dan terkonsentrasi di negara-negara Eropa. Pada tahun 2022 diperkirakan ada tambahan 6,3 MW dengan biaya investasi sekitar Euro 70 juta. Berdasarkan perkembangan teknologi, terdapat dua tipe PLTGL yang telah mencapai TRL 8 dan menuju tahapan produksi masal: 1) Oscillating Water Column (OWC) 2) Floating Buoy. Tantangan utama pengembangan Blue Energy adalah masih mahalnya biaya investasi, misalnya PLTGL Wave Swell Energy (WSE) di Australia yang telah beroperasi selama 1 tahun dengan kapasitas 1 MW LCOEnya masih sebesar 50 cent$/kWh. Kelayakan bisnis Blue Energy sangat sensitif terhadap skala proyek. Contohnya PLTGL Wave Swell Energy (WSE) di Australia yang bisa kompetitif dengan PLTD dengan LCOE 40 cent$/kWh jika kapasitasnya minimal 3 MW. Contoh lain, PLTGL di Pulau Tanimbar, Maluku diperkirakan akan lebih rendah dari BPP setempat jika dibangun dengan kapasitas minimal 11 MW.

For dealing with the energy transition and its disruption effects, the Smart Grid implementation is one of effective solutions. Smart Grid is huge concept, it is not about technology only but also policy and business model to achieve high efficiency, reliability and sustainability on energy power sector. For successful implementation, it needs “alignment between Policy, Strategy and Action”.

The smart energy market can be simply defined as the one that constitutes devices that have inbui... more The smart energy market can be simply defined as the one that constitutes devices that have inbuilt digital technology (mostly with artificial intelligence application) to carry out their daily activities within less any human interference. The smart energy technology has been classified by its component and operation. By component it is divided into power, memory, processing and communication interface. While by operation, it is implemented for emission reductions, security of energy supply, reducing carbon foot print, quality service to end user; and by end-user. Regarding its functions, smart energy mostly refers to an advanced system that is cost-effective, sustainable as well as a secure source of various energies. In this system, renewable energy production, infrastructures, and consumption are integrated using such information and communication technology in a way that enables technologies with the smart use of energy service. Practically, the Smart Energy is segmented into type and end-user consisting four major applications: Smart grid, Digital oilfield, Home energy management systems (HEMS) and Smart solar. Based on the end-user target, the smart energy is bifurcated into commercial, residential and industrial sector. Digital oilfield combines business process management with digital technology in order to maximize productivity and minimize costs in oil and gas operations. HEMS technology, on the other hand, allows the user to adopt technology that is comprised of hardware and software and which can be manually controlled to be used in a household. Both of these platforms seek to incorporate digital means of energy consumption and are positive enablers for the growth of the smart energy market. While the smart solar is a Photovoltaic panel system with an integrated DC power optimizer to optimize each panel operate at its maximum power level regardless of how the other panels on the same string are performing. This allows for more energy to be harvested from the smart module PV systems. Then Smart Grid is commonly defined as an Electrical Grid with Automation, Communication and IT systems that can monitor power flows from points of generation to points of consumption (even down to appliances level) and control the power flow or curtail the load to match generation in real time or near real time. The environmental global movement which create the need of clean and green energy significantly has emerged, is one of the main driven of the smart energy growth. With global warming and other climate issues currently a major policy concern for governments around the ...
