Abstract

ABSTRACTThe off-grid PV system is an alternative power generator as a replacement for the conventional system which is currently still used in production operations at petroleum companies in Indonesia. The application of this offgrid PV system can support oil production operations for companies whose production areas are in remote areas or are still not reached by the PLN network and can reduce the consumption of fossil fuels to run generators so as to reduce greenhouse gas emissions and as a step to utilize the potential of Indonesia's sunlight. This research was carried out using a theoretical study method, namely by processing data obtained from the field using equations obtained from supporting references. This research shows that to meet the electricity needs of a centrifugal pump that operates 5 times a day with one operation of 7.5 kW for 1 hour and the total daily need is multiplied by 2 to calculate cloudy days, 75 kwh of energy is needed a day. The results of the research show that 40 solar panels with a capacity of 450 Wp each installed in series are needed and 80 LIFEP04 batteries made in battery banks totaling 20 banks with 4 batteries each, and 4 5000W inverters so that they can produce 75kWh of power and meet daily load requirements.

Abstract

The Department of Mechanical Engineering, Ambon State Polytechnic has made a machine for peeling coconut fiber. This machine has 4 pry blades which function, when stuck in the coconut fiber, they will make opposite movements, so they can tear the coconut fiber. In the operating process, this machine still uses human power, of course human power has limitations when peeling coconut fiber on a large scale. Therefore, the coconut peeling machine needs to be driven automatically using hydraulic power so that the work process does not depend on human power. The method used in this research is a theoretical study, where data obtained from the field is processed using references and devices that support the construction of electrohydraulic installations. Fluidsim software is needed to test the movement of electrohydraulic installations according to short notation A+ B+ B- A-. The working mechanism of an electrohydraulic installation in controlling the movement of a hydraulic cylinder is shown step by step in the form of a hydraulic diagram and an electro diagram.From the test results, information was obtained that the coconut peeling machine uses 2 cylinders as the driving force for the mechanical system of coconut fiber peeling knives. Working principle of electrohydraulic installation according to the cascade method, in the signal control installation section; relays k1 and k2 turn on alternately in sequence, and in the power control installation section, the relay switch will turn on the solenoids y1, y2, y3 and y4 sequentially according to the short notation.

Abstract

Design of PLTS is an effort to enhance the reliability of electrical power, electrification ratio, and utilization of renewable energy in the oil and gas industry. The availability of electricity is extremely urgent to meet the production process requirements, particularly for the motor-driven SRP pumping system. Currently, the industry relies on PLN and genset electricity for daily production activities. However, the design of a centralized PLTS system is expected to meet the SRP electricity needs in the oil and gas industry. The power grid in the oil and gas industry is obtained from PLN and genset. Therefore, the need for a power plant is evident. Related to the research previously discussed with the title “Design of Centralized PLTS as an Alternative Electricity Supply for Sucker Rod Pump” (Pinky Kartikasari, 2024), this study aims to determine the capacity of panels and batteries required for the development of a centralized PLTS in the oil and gas industry. The method used in this research is quantitative because it involves calculating the capacity of solar panels, daily energy needs, and numerical system analysis. The results show that the total energy requirement for SRP electricity supply is 264 kWh/day. The required capacity of panels is 106 kWp, with a total of 200 monocrystalline panels each with a capacity of 550 Wp. Additionally, there are 128 batteries with a capacity of 24V 200Ah. The inverter used is the PV1800 ECO Series 6.200W type, with 20 units in total. Keywords: PLTS (Solar Power Plant), SRP (Sucker Rod Pump), Oil and Gas Industry

Abstract

Geothermal is a new renewable energy model that comes from the bowels of the earth which is exploited using a Geothermal Power Plant (PLTP) into electrical energy. For high-temperature hot steam, it is used directly as a turbine rotation to produce electricity. The Tulehu WKP which has been explored by drilling 5 wells only produces medium-temperature fluids and is estimated to produce around 7 megawatts (MW) of electricity. One method used to increase the efficiency of PLTP is the binary cycle. The binary cycle is a geothermal fluid power generation system that is used to heat the working fluid using a heat exchanger from the liquid phase to the vapor phase which is then used to drive the turbine. Furthermore, the turbine drives the generator and is converted into electrical energy. This study aims to determine the performance of the Organic Rankine Cycle ORC using isopentane, isobutene and butane working fluids to obtain optimal performance. The method used is to use simulation with the Aspen HYSYS application to obtain good and optimal Organic Rankine Cycle (ORC) fluids. From these problems, the Tulehu Geothermal Power Plant can be built using a binary cycle, so in this study an energy analysis was carried out with the Tulehu Geothermal Power Plant binary cycle in order to produce maximum energy. By applying the binary cycle, the power generated reaches 10 MW.  Keywords: Geothermal, Binary Cycle, Energy

Abstract

Penelitian ini menerapkan sistem buka tutup blade arah horizontal pada kincir angin sumbu vertikal.  Ketika kincir angin berputar,  permukaan blade yang cembung bergerak berlawanan arah datang angin.  Hembusan angin yang menerpa permukaan cembung dari blade,  menghasilkan torsi yang bersifat memutar kincir pada arah berlawanan. Metode yang digunakan untuk menyelesaikan permasalahan gi adalah true eksperiment. Penelitian diperoleh melalui pengujian langsung pada kincir yang menjadi objek penelitian.  Kincir angin ini menggunakan blade yang berbentuk empat persegi panjang dengan permukaan rata.  Jumlah bladr yang digunakan pada saat pengujian bervariasi 2, 3 dan 4, setiap pengujian jumlah blade yang terpasang,  diberikan hembusan angin 250 cm/detik, 180 cm/detik, 112 cm/detik, 86 cm/detik dan 55 cm/detik.Hasil pembahasan data penelitian diperoleh informasi bahwa. Sistem buka tutup blade dapat memutar kincir angin poros vertical, penggunaab blade 3 buah menghasilkan daya yang lebih besar, dari daya yang dapat dihasilkan oleh 2 atau 4 buah blade, semakin besar hembusan angin meningkatkan daya yang dihasilkan dan daya maksimal untuk masing-masing penggunaan blade diproleh pada kecepatan 250 cm/detik, yaitu 2 buah blade menghasilkan daya 0,134 Watt,  3 buah blade menghasilkan 0,16 Watt,  dan 4 buah blade menghasilkan daya 0,15 Watt.

Abstract

AbstrakPenghematan penggunaan bahan bakar pada Oven Tangkring, direncanakan dengan meminimalis ruang oven. Analisa teoritis menjelaskan bahwa permukaan dinding oven merupakan media, terjadinya proses perpindahan panas dari ruang bakar ke udara lingkungan atau disebut kehilangan energy (Heat lost). Bila volume ruang oven diperkecil, maka luas dinding ovenpun berkurang. Menggunakan tinggi api yang sama, diharapkan pengurangan luas dinding ini akan meningkatkan suhu ruang bakar. Sehingga untuk memanggang kue pada kondisi temperature ruang bakar yang sama dengan oven konvensional, maka perlu mengurangi tinggi api. Tindakan ini diharapkan berpengaruh pada penggunaan bahan bakar. Metode yang digunakan untuk mendapat informasi terhadap kemampuan oven selinder memanggang kue hingga matang, adalah metode true eksperimant. Data hasil penelitian diperoleh melalui perlakuan pengujian di laboratorium. Sedangkan data yang diperoleh, selanjutnya diolah dengan menggunakan metode regresi linear berganda.Pengolahan data hasil eksperimen, diperoleh informasi bahwa oven bentuk selinder memanggang 2 buah adonan roti dengan berat 750 gram/adonan, hingga matang menggunakan bahan bakar sebanyak 46 ml, memanggang 2 buah adonan kue Zebra dengan berat 1.000 gram/adonan hingga matang menggunakan bahan bakar sebanyak 113 ml, dan memanggang 2 buah adonan Tar Gula Merah dengan berat 1.000 gram/adonan hingga matang menggunakan bahan bakar sebanyak 72,6 ml, dan Memanggang 2 buah adonan kue Zebra dengan berat masing-masing 1.000 gram, oven bentuk selinder lebih hemat 53,8 ml, dibandingkan menggunakan oven bentuk kotak.
