Abstract

Penambahan hidrogen bersama bahan bakar besin dapat meningkatkan kinerja dan efisiensi motor, tetapi setelah batas tertentu, hidrogen mulai muncul efek samping, terutama karena rasio oksigen bahan bakar menurun. Generator elektrolisis hidrogen merupakan sebuah alat yang dapat menghasilkan gas hidrogen dan oksigen pada proses elektolisis air. Gas tersebut dapat diaplikasikan sebagai campuran bahan bakar dan udara untuk meningkatkan daya motor; dengan diinjeksikan bersama udara yang masuk ke ruang pembakaran. Tujuan penelitian adalah mengidentifikasi pengaruh pemakaian generator elektrolisis hidrogen terhadap kinerja motor bensin.  Hasil menunjukkan pengaruh generator elektrolisis hidrogen terhadap peningkatan kinerja motor bensin, yaitu daya efektif sebesar 18,21% (4000 rpm), pemakaian bahan bakar yang berkurang sebesar 15,34% (3600 rpm), serta meningkatkan efisiensi thermal 17,36% (4000 rpm).

Abstract

Papua province has nine small islands that are inhabited, but there is no access to electricity on these islands. The solution is the use of sea wind as a source of energy for a small power plant. This study aims to determine the potential of sea wind as an alternative source of electrical energy on the north coast of Papua Province. Data Measurement is carried out using an HP-866B anomometer on a hill near the coast to maximize the sea wind. There are two methods used in this research: the minimum-maximum value to determine the wind speed range and linear regression to determine the distribution pattern of the wind. The range of the sea wind is 0.2–6.18 m/s. If the minimum speed is limited to 1.6 m/s, then the range of kinetic energy is 5.59–322.22 Joules/s, mechanical power is 5.59–322.22 Watts, and actual power is 0.57–33.13 Watts. Meanwhile, the pattern shows that the sea wind from the north coast of Papua Province blows with two trends: constant and increasing, specifically in the afternoon and evening. Based on that, the development of a wind power plant on the north coast of Papua Province can be carried out using a multi-turbine system to increase the actual power that can be obtained.

Abstract

The type of drying device known as a hybrid dryer is a tool that harnesses solar energy and the heat generated by a biomass fuel-powered heat exchanger. This study was conducted to assess the performance of the hybrid dryer by analyzing the parameters of the device itself and the dried material. The research was carried out experimentally using a solar collector and a biomass furnace (as a heat exchanger) to heat the air. The solar collector used consists of 0.35 mm thick, black-painted zinc, coated with 5 mm thick glass, and installed at a 20-degree angle. The heat exchanger pipe used has a diameter of 1.25 inches and is made of galvanized pipe. The tested sample is corn seeds with an initial moisture content of about 24.6%. The experimental results show that in the drying process using a solar dryer, the initial moisture content of 24.8% was successfully reduced to 14% at 5.50 h (rack 1), 6.50 h (rack 2) and 7.00 h (rack 3) with a thermal efficiency of 24.25%. Meanwhile, in the hybrid drying process, the required time is approximately 5.00 h (rack 1), 5.50 h (rack 2) and 6.00 h (rack 3), with a efficiency of the drying equipment used is 21.048±5.690% (hybrid) and 22.706±6.437% (solar).

Abstract

Barapen, a cooking tradition in various indigenous Papuan communities. To date, various social science studies have been conducted to examine social values, business economics, and political economy. While research in the aspects of applied science has yet to be conducted to study the phenomenon of heat transfer by natural convection from hot stones to food in cooking packs, this research was conducted. The purpose of this research is to study the phenomenon of heat transfer by natural convection from hot stones to food in cooking packs. In this study, a square-shaped artificial pool (260 cm x 210 cm x 50 cm) with white batah stone walls was used to cook food in a barapen. On the four walls, a type K thermocouple is inserted to measure the temperature at 3 layers, which will be the object of research. The ingredients are vegetables, sweet potatoes, and chicken meat that has been cut and stoned. As a discussion, the temperature gradient between layers occurs due to the difference in the amount of volumetric heat against time in each layer. The difference in the amount of heat in each layer is due to the difference in the density of the hot vapor trapped in each layer. Thus, it can be said that the cooking of food in Barapen occurs due to natural heat convection.

Abstract

Reusing exhaust gas based on potential energy that has not been completely burned can absorb heat in the combustion chamber thereby increasing the performance of diesel engines. The aim of this research is to determine the effect of using an EGR venturi scrubber on the performance of a single cylinder diesel engine. This research was carried out on a single cylinder diesel motorbike with a capacity of 200cc. Testing was carried out using an EGR venturi scrubber with valve variations of 10%, 20% and 30% compared to standard (0% EGR). Test data was obtained through VDAS technology software by loading the water entering the dynamometer at the test installation. The research results showed that testing using the EGR venturi scrubber on diesel motorbikes had an influence on engine performance. The best performance was obtained by using a venturi scrubber with a valve opening of 30%, where at a maximum rotation of 3000 rpm the torque was 6.57 Nm, the effective power was 2110 Watts, the average effective pressure was 4.72 bar, the specific fuel consumption was 0 .0549 kg/kWh, and a thermal efficiency of 58.42%.

Abstract

The operational efficiency of mid-capacity (140 MW) Combined Cycle Gas and Steam Power Plants (CCGT) remains underexplored concerning the DIN-VDI 4661 standard, which defines key quality metrics for energy systems. Addressing this gap is crucial for establishing standardized benchmarks to optimize performance and reduce energy losses. Existing studies mainly focus on Combined Cycle Gas Turbine (CCGT) units outside the 100–180 MW range and often do not explicitly follow DIN-VDI 4661, limiting efficiency comparisons and hindering targeted optimizations. This study simulates a 140 MW CCGT using Ebsilon® Professional software, incorporating DIN-VDI 4661 guidelines to assess eight quality indicators, including thermal efficiency, fuel utilization, and power-to-heat ratio. The model integrates gas and steam turbines, heat recovery, and auxiliary components, with input parameters validated against industry data. Energy balance analysis and sensitivity tests identified loss points. Results show a gas turbine thermal efficiency of 31.39%, steam turbine efficiency of 39.59%, and total system efficiency of 48.42%. However, significant energy losses (52% of input energy) were observed, mainly in gas turbines (87,000 kW) and steam turbines (56,000 kW). These findings highlight the need for design optimizations, such as improving heat recovery and turbine efficiency, to meet DIN-VDI 4661 benchmarks.
