Abstract

ABSTRACT The kinetic energy was produced by a moving vehicle can be used to generate power by using a speed breaker. The kinetic energy is converted into mechanical energy by altering a reciprocating connecting rod into rotation of flywheel, then it is transmitted to the generator in order to produce electrical energy. The purpose of this study was to determine the electrical energy generated from the crankshaft type speed breaker. Speed breaker used has 3 ramps with a maximum ramp height of 10 cm. the load and speed of vehicles passing the ramp are varied 72 kg, 82.5 kg, 88.7 kg at speeds of 5 km/h, 10 km/h, 15 km/h. The result of the study shows that a vehicle with the mass of 88,7 kg was able to generate a 19 V of electric voltage, 32 A of electric current and 486,4 Watts. That power is stored in a 12 V and 3 Ah batteries that needed 0.094 hour for charging.

Abstract

The raw material for making springs must have mechanical properties following the spring standards because the spring was receiving a dynamic load. This study aimed to improve the mechanical properties of the metal used as a material for making leaf springs. The material used is JIS SUP 9 steel which has a carbon content of 0.52-0.6%. The method used in this research is quenching and quench-tempering heat treatment. The used cooling medium was water, and the tempering temperature was at 300 °C. The mechanical properties of each specimen were tested by Vickers hardness and tensile test. The best heat treatment for material preparation is a quench-temper process, and the result was met with the manufacture of leaf spring. The findings explained that the hardness and tensile strength values were 504 HVN and 1555 N/mm2, respectively. This study could be a new insight for the leaf spring manufacture in the automotive industry.

This study aims to obtain the appropriate design parameters for the manufacture of screw turbines. This research was focused on blade dimensions and turbine screw pitch distance. The calculations were performed using several screw turbine fixing formulations. The design results show that the optimum blade diameter and turbine pitch range are 0.213 m and 0.312 m at 0.2 m3 / s of turbine inlet water flow and 563.3 Watt turbine shaft output power. The turbine screw test results of the design were carried out in the river flow of Puri Kedaton Housing, Pematang Gajah Village, Rt 13, Jambi Province. The test results show that the highest turbine power occurs at 30 kg shaft loading with a turbine output power of 445 Watts and an efficiency of 78.9%.

Abstract

One of the parameters that affect the citronella oil distillation process is the pressure and temperature of the steam. The aim of this research was to determine the optimal working pressure and temperature for the distillation process. The distillation method uses the direct steam type, by varying the pressure in the boiler, namely 2 bar, 2.5 bar and 3 bar. Steam temperature increases with increasing working pressure, namely 100 - 110ºC. The raw material for citronella used  5 kg with a long distillation process of 4 hours. The test results showed that the highest amount of oil and yield occurred at a pressure of 3 bar and a temperature of 110ºC, 19 ml and 0.32%, respectively. The color of the oil produced pale yellow to brownish yellow with a specific gravity of oil at 25ºC which is 0.878 gr/ml. Citronella oil has good quality according to the SNI 06-3953-1995 citronella oil quality standards.

Abstract

Salah satu yang mempengruhi peningkatan efisiensi pompa adalah geometri sudu impeler. Tujuan dari penelitian ini adalah untuk mendapatkan desain geometri impeler terbaik pada mini pompa sentrifugal. Geometri impeler yang digunakan dalam penelitian ini memiliki tiga variasi yaitu: tipe impeller radial miring, radial melengkung, dan radial airfoil. Sudu impeler didesain selanjutnya dibuat mengunakan mesin 3D print dengan bahan filamen PLA. Motor penggerak pompa yang digunakan adalah dinamo 775 DC 12Volt dengan kecepatan putaran pompa diatur menggunakan potensio pada 2000 rpm, 2150 rpm, 2300 rpm, 2450 rpm, 2600 rpm, dan 2700 rpm. Hasil pengujian menunjukkan bahwa perbedaan geometri sudu impeler mempengarui efesiensi mini pompa sentrifugal. Efisiensi tertinggi terjadi pada tipe impeler radial melengkung dengan nilai efesiensi mencapai 19,35% pada putaran 2700 rpm. Kondisi ini lebih baik daripada tipe impeler lainnya dengan trend kenaikan efesiensi meningkat seiring dengan peningkatan putaran pompa.

Abstract

Heat Recovery Steam Generator (HRSG) adalah komponen penting dalam sistem Pembangkit Listrik Tenaga Gas dan Uap (PLTGU) yang memanfaatkan panas sisa dari gas buang turbin gas untuk menghasilkan uap yang digunakan dalam turbin uap. Efisiensi HRSG berperan signifikan dalam meningkatkan efisiensi termal keseluruhan siklus gabungan (combined cycle) PLTGU. Penelitian ini bertujuan untuk mengevaluasi kinerja dan efisiensi termal HRSG berdasarkan data operasional harian, serta membandingkannya dengan efisiensi desain dan standar industri. Berdasarkan hasil perhitungan, efisiensi termal aktual rata-rata HRSG adalah sebesar 82,90%, dengan nilai tertinggi sebesar 83,21% pada hari ketiga dan terendah sebesar 82,28% pada hari kelima. Nilai ini masih berada dalam kisaran standar efisiensi HRSG, yaitu 75-85% menurut referensi yang digunakan (V. Ganapathy, 1996), dan hanya berbeda sedikit dari efisiensi desain sebesar 85,91%. Perbedaan efisiensi ini disebabkan oleh fluktuasi laju alir massa bahan bakar serta variasi kondisi operasi lainnya. Kesimpulan dari penelitian ini menunjukkan bahwa efisiensi termal HRSG yang dioperasikan masih berada dalam batasan yang diinginkan, meskipun terdapat ruang untuk perbaikan lebih lanjut guna mencapai efisiensi yang mendekati desain. Optimasi operasi dan pemeliharaan rutin direkomendasikan untuk mempertahankan dan meningkatkan efisiensi sistem secara keseluruhan

Abstract

Archimedes Screw turbine is a type of turbine that can operate at low heads. One of the parameters that influences turbine performance is the tilt angle of the turbine shaft. This research aims to determine the effect of the turbine shaft tilt angle on the performance of the Archimedes screw turbine using experimental methods. The experiment was carried out in the river of Pematang Gajah Village, Jambi Province, by varying the tilt angle of the turbine shaft, namely 10°, 20°, 30°, 40°, and 50°. The test results showed that the highest turbine efficiency occurred at a turbine tilt angle of 30° with an average efficiency value reaching 78%. This condition occurs because the flow through the turbine blade is less compared to other turbine shaft tilt conditions so that the fluid force is completely converted into energy. The electrical energy produced by turbine generators can reduce dependence on electricity supplies from the central grid and become more energy-independent. In addition, stable and affordable energy sources can improve the quality of life and support the social and economic development of society.

Abstract

The performance of a centrifugal pump is influenced by the design of the impeller, one of which is the number of impeller blades. The objective of this study is to determine the optimal impeller blade number geometry for a centrifugal pump. The type of impeller used is a backward-curved radial impeller with variations in the number of blades: 5, 6, 7, and 8. The impeller and pump casing were fabricated using a 3D printing machine with PLA filament material. The results of the study show that the highest pump discharge occurred with 8 blades, reaching a flow rate of 41.34 liters per minute at a speed of 2541 rpm, with a pump efficiency of 33.69%. The greater the number of blades, the higher the efficiency and capacity of the pump. However, this condition needs to be further reviewed for additional blade numbers to determine the optimal impeller geometry for centrifugal pump design.
