Due to the massive volume of water requirements, coal mining company must carry out water conservation. Moreover, the waste water from a coal mining process contains pollutants from mining activities that are dangerous for the environment. Therefore, the waste water must be treated to annihilate any harmful pollution before the water can be flowed back to the water resources. Stringent government regulation requires companies to report waste water quality regularly. The task to collect waste water quality data is laborious as a company needs operators to measure and checks the parameters periodically. Therefore, an on-line system to measure and collect the information is in dearth. However, expensive industrial sensors pose difficulties for small-scale coal mining. The paper presents the potential of low cost sensor for waste water online monitor...

Particularly, in 2020, the ministry of energy and mineral resources of Indonesia has set a target to reduce carbon emission by 26%. For that reason, companies in Indonesia have to comply with the emission target. However, there is tradeproductivity must be weighed against the environmental effect such as carbon emission. Nowadays, distinguish excessive energy in a company is still challenging. The company rarely has skilled person that capable to audit energy consumed in the company. Auditing energy consumption in a company is a lengthy and time consuming process. As PT Astra International (AI) have 220 affiliated companies (AFFCOs). Occasionally, direct visit to audit energy consumption in AFFCOs is inevitable. However, capability to conduct on-site energy audit was limited by the availability of PT AI energy auditors. For that reason, PT AI has developed a set of audit energy tools or Astra green energy (AGEn) tools to aid the AFFCOs auditor to be able to audit energy in their own company. Fishbone chart was developed as an analysis tool to gather root cause of audit energy problem. Following the analysis results, PT AI made an improvement by developing an AGEn web-based system. The system has capability to help AFFCOs to conduct energy audit on-site. The system was developed using prototyping methodology, object-oriented system analysis and design (OOSAD), and threetier architecture. The implementation of system used ASP.NET, Microsoft SQL Server 2012 database, and web server IIS 8.

The Cash Waqf Management is expected to become one of the alternative instruments for the poverty alleviation programs in Indonesia. These programs require huge amount of fund that cannot be provided thoroughly by the government. Therefore, initiation of new sources of fund for such a program is inevitable. In the Islamic sosioeconomic concept, there is a source of social fund that is economically and politically free of charge, namely cash waqf. In this concept, Nadzir (cash waqf fund manager) collects the fund from Waqif (cash waqf payer) and invest the money in the real sector and in any syariah-based investment opportunities. Nadzir will then allocate profits and returns gained from the investments to poverty alleviation programs. Nadzir is obliged to maintain the amount of fund in such a way that it does not go below the initial amount. Therefore, Nadzir not only should be highly capable, but also needs an experienced financial institution in helping SMEs development efforts. Using the system dynamics methodology, we try to design the structure of cash waqf system and simulate the behaviour of cash waqf model.

One of the barriers to adopting BIM is BIM skills among graduates are still rare. Therefore, higher education institutions have to adopt BIM into their curriculum. However, as BIM is a new concept in construction engineering, many higher education institutions have a problem integrating BIM. Therefore, the paper proffers a syllabus to integrate BIM in a vocational higher education institution. The research methodology follows the Tyler model of curriculum development. It started with a review of prominent BIM integration into higher education research. Then, discussion with BIM practitioners from the industry to acquire information on current BIM-related job specifications in Indonesia. The team teacher then discussed and analyzed the results to create an initial syllabus. Further, the students' performance and feedback are observed during two years of course offering from 2019 to ...

However, in recent years youth unemployment remains high. The high unemployment rate is attributed to the lack of skills of vocational school graduates. The skills of these graduates do not match the technologies used in the industry. Astra Manufacturing Polytechnic (Polman Astra) aims to remedy the issue by initiating a blended learning program to transfer industrial knowledge for vocational school (SMK) teachers in Greater Jakarta. A descriptive study was conducted to SMKs in North Jakarta to understand school readiness level to implement the program. Furthermore, the research also analyzes the teacher perception of industrial knowledge. Following the questionnaire results, the study reveals that the schools surveyed are generally ready to implement e-learning but require further training. Further results indicate that exposing teachers to industrial knowledge is crucial in order to keep up with...

The product prototyping process requires a good knowledge management in order to produce high quality prototypes. During the product prototyping development project, project documentation is often improperly managed. As a result, it potentially causes the loss of the obtained knowledge. Consequently, the lost knowledge cannot be reused when working on similar project. To manage the documentation properly, a research that can manage documentation prototyping has been done. The research is intended to store the knowledge of product prototyping. A culture of knowledge sharing is a major source of knowledge management system development, hence a preliminary research is needed to understand the current knowledge sharing culture in Polman Astra. Data were collected through a questionnaire consisting of closed questions using the 5 Likert-scale. The quest...

Therefore, construction management is very important to ensure completion of construction projects are within schedule and budget. Utilization of building information modeling (BIM) can increase the efficiency of a construction project. However, the implementation of BIM in Indonesia is still not known. This paper is intended to review the implementation of BIM in Indonesia through literature analysis. To find BIM articles in Indonesia, Firstly, searching was limited to English articles published in reputed journals or conferences. However the results were limited, then the search was expanded to the article using Indonesian languages that published in journal and conference. Based on the number of articles, the results showed that BIM research in Indonesia is still in a dearth. Furthermore, BIM study cases were conducted in a limited location and within a small population. Nevertheless, the literature shared the conclusion that BIM can increase project efficiency, but the implementation was hindered by high initial investment cost, inadequate human resources, small demand, and technology resistant. The research contributes to providing a current reported level of BIM implementation in Indonesia. In the future research to study of BIM implementation comprehensively in Indonesia is eminent.
