Ketika masyrakat menyadari bahwa kekuasaan setiap individu perlu dikontrol oleh hukum maka hak dan berkewajiban tidak ditentukan oleh yang berkuasa, melainkan oleh yang diakui bersama suatu kebenaran. Jejak kekerasan dalam hukum selalu terlupakan oleh perjalanan waktu dan tersembunyikan oleh berbagai fiksi tentang moralitas penegakan hukum. Akibatnya, kita sering tidak mengenali lagi kekerasan yang diproduksi oleh berbagai produk hukum dan menganggapnya sebagai sebuah hal yang wajar, bahkan tidak jarang menganggapnya sebagai sebuah hal yang wajar, bahkan tidak jarang mengagnggapnya sebagai keharusan moral dalam kehidupan masyarakat di Indonesia. Sebagai contoh tindakan /penganiayaan dan pembunuhan yang dilakukan dalam berbagai peristiwa main hakim sendiri atau konflik diberbagai daerah justru sering memperoleh dukungan dan pengesahan dari lingkungan masyarakat sekitar. Akibatnya, ketika aparat keamanan mengambil tindakan hukum terhadap pelakunya, mas...

Thermal load is a big factor that affects energy consumption by air conditioners. For this reason, the thermal load of a room needs to be reduced. One strategy to reduce the room's thermal load is the use of phase change materials (PCM). Coconut oil is a PCM that has a freezing temperature in the range of 21.30 – 21.73 oC which will be investigated in this study. The test was carried out with three room models; without PCM, with PCM partition, and PCM partitioned with night air. Each room model carried out 3 variations of air temperature, as well as 4 variations of the heater. The results showed that the use of coconut oil PCM as a room partition can help reduce the room temperature to 2oC below the AC temperature with a decrease in the use of electrical energy reaching 400 Watts. Air conditioner (AC) merupakan alat untuk mengondisikan udara pada sebuah ruangan. Penggunaannya berdampak pada konsumsi energi listrik. Beban te...

Biasanya media promosi SMP Bhakti Mulya yang paling banyak digunakan adalah media konvensional, seperti spanduk dan brosur. Akibatnya, daya tarik untuk para peminat disekolah SMP Bhakti Mulya menjadi berkurang dikarenakan informasi mengenai beberapa fasilitas yang terdapat di SMP Bhakti Mulya kurang tergambarkan dengan jelas untuk para calon siswa baru. Maka dibutuhkan suatu media promosi sekolah bagi calon siswa baru yang lebih kreatif dan menarik yang dapat memberikan gambaran visualisasi 3D dengan menggunakan teknologi augmented reality. Augmented Reality (AR) adalah suatu lingkungan yang memasukkan objek virtual 3D kedalam lingkungan nyata secara real-time karena dalam hal ini dikarenakan perpaduan dari script pemrograman serta seni 3 Dimensi yang diwujudkan kedalam sebuah aplikasi secara bersamaan.

Similarly, stem cell therapies have also been applied in clinical settings, includingthe spine. However, stem cells' delivery to the spinal region requires delicate procedures, demanding reliable introducers in addition to the surgeons' psychomotor skills. The introducer is a tubular sleeve to guide a syringe needle to deliver and draw fluids into and from the body, respectively. To date, there is no introducer dedicated to spinal stem cell deliveries. Our group proposed a dedicated introducer for spinal stem cell therapies, which consists of a needle and a hub (a base part of an introducer for gripping and handling). We focused onthe weighting property method (WPM) to select four polymer candidates for the hub:polystyrene, polycarbonate, polypropylene, and polyethylene. Prior to WPM, the mechanical integrity of the hub candidates was analyzed using the finite element method to determine the von Mises Stress (vMS) values. Accordingly, the vMS for each case and the material was compared with the respective tensile strength (TS), thereby vMS:TS ratio (MTR).MTR was included as one of the properties in WPM, in addition to prices, critical radiation doses, hardness, water absorption, and isopropyl alcohol resistance.According to the WPM calculation, polycarbonate received the highest score, thereby recommended for further introducer fabrications.

On the other biomass is an alternative energy source that is abundant, including empty bunches of oil palm (TKKS), but has poor combustion properties compared to coal when burned directly. The properties of biomass burning can be improved by certain treatment, one of which is through the process of torrefaction. Biomass torrefaction has a calorific value equivalent to sub-bituminous coal B, so it has the potential to be used as an alternative fuel for coal. The purpose of this study was to determine the maximum temperature that occurs in the burner. In this study co-combustion was conducted on simulation of ANSYS program with powder system (pulverized combustion) because this type in recent decades is widely u...

Research paper thumbnail of Recent advances in 3D printed wound dressings

THE 5TH BIOMEDICAL ENGINEERING’S RECENT PROGRESS IN BIOMATERIALS, DRUGS DEVELOPMENT, AND MEDICAL DEVICES: Proceedings of the 5th International Symposium of Biomedical Engineering (ISBE) 2020, 2021

Regarding the problematics, researchers enhance the functionalities of wound dressings. One of the enhancement approaches is using 3D printing technology. The use of 3D printing has enabled many types of wound dressings, including biodegradable multi-material, cell-laden, and drug-eluting wound dressings. The use of 3D printing even allows for a wound dressing with a 3D construct, facilitating the wound dressing placement at the wound bed. Unfortunately, the 3D printed wound dressing technology has never been reviewed, to the extent of our knowledge. In this report, we aim to reflect on the recent advances in 3D printed wound dressings. Reports regarding the 3D printed wound dressing were collected from the Google Scholar database. The search was limited from 2015 to 2020 with a logic search: “3D printed” AND “wound dressing,” which words can be found in the entire article. Irrelevant reports were excluded manually, thereby resulting in the 24 selected articles. The selected articles were subsequently reviewed in terms of the materials-efficacy analysis and 3D printing mechanism. The extracted information from all articles concluded that alginate is the most used material for 3D printed wound dressing, while the most used 3D printing mechanism is the pneumatic FDM. In terms of efficacy, wound dressings presented an antimicrobial performance against Gram-positive and Gram-negative bacteria, as well as biocompatibility to epidermis and dermis cells.

While, literature study and interview will be used to know deeper about the culture values in the Pendem Temple. The result of this research is there are mathematics elements (ethnomathematics) in Pendem Temple, they are : the rectangle concept,right triangle, circle, reflection, and solid geometry. In this term can be concluded that mathematics enters in every life aspects, for example in culture aspect.

THE 5TH BIOMEDICAL ENGINEERING’S RECENT PROGRESS IN BIOMATERIALS, DRUGS DEVELOPMENT, AND MEDICAL DEVICES: Proceedings of the 5th International Symposium of Biomedical Engineering (ISBE) 2020, 2021

Chronic and acute wounds interfere with personal aesthetics and appearance. Regarding the problem... more Chronic and acute wounds interfere with personal aesthetics and appearance. Regarding the problematics, researchers enhance the functionalities of wound dressings. One of the enhancement approaches is using 3D printing technology. The use of 3D printing has enabled many types of wound dressings, including biodegradable multi-material, cell-laden, and drug-eluting wound dressings. The use of 3D printing even allows for a wound dressing with a 3D construct, facilitating the wound dressing placement at the wound bed. Unfortunately, the 3D printed wound dressing technology has never been reviewed, to the extent of our knowledge. In this report, we aim to reflect on the recent advances in 3D printed wound dressings. Reports regarding the 3D printed wound dressing were collected from the Google Scholar database. The search was limited from 2015 to 2020 with a logic search: “3D printed” AND “wound dressing,” which words can be found in the entire article. Irrelevant reports were excluded manually, thereby resulting in the 24 selected articles. The selected articles were subsequently reviewed in terms of the materials-efficacy analysis and 3D printing mechanism. The extracted information from all articles concluded that alginate is the most used material for 3D printed wound dressing, while the most used 3D printing mechanism is the pneumatic FDM. In terms of efficacy, wound dressings presented an antimicrobial performance against Gram-positive and Gram-negative bacteria, as well as biocompatibility to epidermis and dermis cells.
