Abstract

Along with the development of technology, the need for plastic will continue to increase. The high population is certainly directly related to the large volume of waste generated. Therefore, the Directorate of IKM Region I took the initiative to facilitate IKM Plastic Waste Processing to be recycled in order to overcome environmental problems that are being faced by the Langsa City Regional Government. The purpose and objective of this activity is to procure machines/equipment that will be used as production facilities for the Recycled Plastic Waste Processing IKM in Langsa City. The research methodology is carried out in the form of implementation stages, namely 1) coordination and survey with related parties, 2) delivery, installation and testing, 3) handover of goods/works. The output of this research is 1 unit of bottle washer. The result of this research is to facilitate the IKM Production Facility for Recycling Plastic Waste Processing in Langsa City and it has been carried out according to the specifications and the time specified. The implementation of Machinery and Equipment/Facility Assistance activities is carried out in Sambas Regency, with the help of machinery/equipment facilities in the form of 1 unit of bottle washing machine.

Abstract

Banjir merupakan permasalahan yang paling sering terjadi di kota besar selain kemacetan. Hal ini disebabkan akibat daerah resapan air berkurang karena semakin banyaknya pemukiman di daerah perkotaan tersebut. Selain makin banyaknya pemukiman, hal lain yang menyebabkan terjadinya banjir adalah buruknya sistem drainase, kondisi saluran nya, limpasan air yang tinggi serta kurangnya dimensi drainase sehingga tidak dapat menampung semakin banyaknya volume air sehingga menjadi luapan air. Salah satu bentuk mitigasi bencana pada penelitian ini adalah alat sensor banjir. Alat sensor ini akan mendeteksi level air dan memberikan sebuah suara peringatan untuk masyarakat sekitar. Hal ini diharapkan agar menjadi salah satu early warning system terhadap bencana banjir. Metode yang dilakukan adalah rancang bangun alat sensor banjir. Diawali dengan studi literature, survey lokasi penempatan alat sensor banjir, persiapan alat dan bahan, permbuatan alat sensor banjir, pengujian alat dan evaluasi serta diakhiri dengan penerapan di lokasi yang telah ditentukan. Hasil yang didapatkan pada penelitian ini adalah perancangan alat sensor banjir sesuai dengan yang diharapkan. Selain itu, alat sensor banjir ini telah diterapkan di Puri Cipageran Indah Kota Cimahi.

Abstract

Over time, the consumption of electrical energy needed in Indonesia is getting bigger. Various efforts continue to be made either by seeking new energy potential or by developing existing technologies. Apart from the increasing need for electrical energy, efforts are made to supply the needs of electrical energy by utilizing the potential and conditions that exist in certain areas. Water energy has been widely utilized and used for power generation. The potential of water as an energy source can be used as a provider of electrical power. One of the uses of water energy is to make hydroelectric power plants. The purpose of this study is to design a portable water turbine design and find out the results of the calculation of the analysis of electrical power produced. The research method used is the analysis of water turbine design using the SolidWorks application to be able to find out the shape of the turbine that has simple, portable properties and can be carried anywhere. The size that meets the desired criteria is 10 cm for diameter and 4 cm for height. After designing the turbine design, then the calculation and analysis of the power released by the water turbine is carried out. The data needed to perform the calculation are water discharge 1.48×10-5 m3/s, head 6×10-2 m, water density 1000 kg/m3, gravity acceleration 9.81 m/s2, turbine efficiency 12.6%. Using the turbine power formula, the turbine power with a water discharge value of 1.48×10-5 m3/s is 11 Watts. Then the 2nd calculation was carried out with the value of the water discharge used of 9.6×10-5 m3/s and turbine efficiency of 24.9%. After calculation, the turbine power value of 14 Watts was obtained.

Abstract

The chassis is an important component car which functions to support the load on the vehicle and has a strong construction. The chassis, as the main support for all vehicle componentsy. Increased fuel use and rising global crude oil prices have encouraged research into energy saving cars with special designs that can reduce fuel consumption and pollutant emissions. The design process with variations in rollbar shape and variations in cross sectional shape with 6061 aluminum material using Autodesk Inventor 2024 software. After the design process is complete, stress analysis test stage is carried out to obtain analysis data, namely von misses stress, strain, displacement, safety factor. The results of the chassis design using concept B with a pipe cross-sectional shape and rollbar fillet model are more recommended, because it has better von Mises stress value and a better safety factor, besides that the concept B chassis design is easier in the assembly process with prototype type energy efficient car body.

Abstract

This study aims to evaluate the performance of bifacial photovoltaic (PV) panels under different reflective surface conditions in a tropical urban environment, specifically in Bandung, Indonesia. Bifacial PV systems offer the advantage of capturing solar radiation from both the front and rear sides, with performance significantly influenced by the surface beneath the panels. The experiment involved three surface types: asphalt, untreated paving blocks, and paving blocks coated with white paint. Each panel was installed at a fixed 8° tilt facing north, and data were collected from 09:00 to 15:00 local time. The results indicate that the white-painted surface produced the highest power output, reaching up to 410 Watts, followed by paving blocks at 390 Watts and asphalt at 370 Watts. Although all surfaces received a similar radiation pattern, their differing reflectivity affected the amount of radiation reaching the rear side of the bifacial panels. The white-painted surface, characterized by high reflectance, not only enhanced rear-side radiation capture but also maintained a more stable power output after peak solar hours. These findings highlight the critical role of surface reflectivity in optimizing bifacial PV performance and support the strategic use of surface materials in PV system deployment, particularly in tropical climates. This study contributes valuable empirical data to the growing field of bifacial PV applications and offers practical insights for improving energy yield in real-world tropical settings.

Abstract

This study evaluates the performance of R290 refrigerant as an alternative to R404A in block ice-making machines based on vapor compression cycles. The method used is a quantitative experimental approach with direct testing of compressor power, condenser power, evaporator power, and coefficient of performance (COP) parameters. Test results indicate that R290 has lower power consumption and a higher COP compared to R404A, with a COP of 3.22 (R290) versus 2.48 (R404A). Additionally, R290 has a significantly lower global warming potential (GWP), making it more environmentally friendly. The more stable and efficient thermodynamic performance of R290 supports its effectiveness as an economical and sustainable alternative refrigerant for modern cooling applications.
