Abstract

Abstract Renewable energy is one of the alternative energies for the application of effective energy in the future because it also takes into account the increasing dependence of humans on the use of fossil energy which will reduce the availability of fossil energy and renewable energy can also be used as an alternative energy source whose distribution is For areas that have not been reached by PLN because of the large and centralized power generation system, one solution is the use of renewable energy generation, one of which is wind energy. Wind energy generators have the advantage that the energy costs are relatively cheaper, but the challenge is that this plant is designed for areas with medium and high wind speed groups so that the performance of this plant will decrease when applied in low pressure areas, so optimization is needed on the wrong design. The only thing is the addition of a shroud (wind lens) on a wind turbine that can increase performance twice as much as a wind turbine without a wind lens. For the test, a wind turbine design test variable was carried out using a windlens and a wind turbine without a wind lens with wind speeds of 3 m/s, 4 m/s and 5 m/s. The best test results used a windlens Cp max = 0.898 and Ct max = 0.58 at a wind speed of 3 m/s.

Abstract

The need for energy continues to increase in line with increasing development, especially in the industrial sector, economic growth and population growth. Petroleum has become the main energy source in meeting domestic energy needs. At present, petroleum is also a commodity producing state revenues and foreign exchange. The growing demand for petroleum continues, but reserves are running low. The diminishing world oil reserves, including Indonesia, has encouraged the government to reduce people's dependence on fuel oil. Sea water is a mixture of 96.5% pure water and 3.5% other materials such as salt and dissolved gases. Basically, water sea contains high NaCl compounds and by H2O decomposed into Na+ and Cl- The voltage produced from Seacell is theoretically capable of producing Electricity voltage. Test results of seawater on the influence of copper and aluminum cross-sectional area, that the cross-sectional area of ??copper and aluminum plates is very influential on the amount of electrical energy produced. Where is the cross-sectional area of ??copper and aluminum 100 cm2 = 0.00672 Watts, 150 cm2 = 0.0126 Watts, and 400 cm2 = 0.0354 Watts. This shows that electrical energy can be generated through copper plate and aluminum electrodes and sea flow as a electrolyte

Abstract

In an autonomy region era which is signed with appearance many new district ( Kabupaten ) is in order to faster the increasing economic country society . This program should be supported with an existence of electric power The fact that electric power isn't enough for all society especially in the country. It could be understood because generally the distance between a country is far enough and a few number of people in village . All of that make a big invest. Amount complex, the electric power from PLN far from enough. In the village is existence potential water power; nature water fall and irrigation canal that have 2.5 meters height and 250 liter's/second quantities. If two of potential water power could be exist all years long , it can be utilized to move turbine as a micro hydro electric power generator that very potential' in small village.

Abstract

Mini crane hidrolik hadir sebagai jawaban atas keterbatasan industri kecil dan rumah tangga dalam mengangkat serta memindahkan beban berat secara praktis, efisien, dan aman. Penelitian ini bertujuan untuk merancang, membangun, serta menguji kinerja mini crane hidrolik dengan kapasitas angkat hingga 2 ton. Metode penelitian menggunakan pendekatan Research and Development (R&D) yang mencakup studi literatur, desain perancangan, pemilihan material, proses fabrikasi, hingga pengujian fungsional terhadap alat yang dihasilkan. Hasil penelitian menunjukkan bahwa mini crane hidrolik mampu mengangkat beban mulai dari 500 kg hingga 2000 kg dengan ketinggian angkat 1,45 meter, di mana tegangan lentur yang dihasilkan mencapai 22,72 kg/mm² pada beban 500 kg dan meningkat menjadi 90,90 kg/mm² pada beban 2000 kg. Konstruksi yang dirancang terbukti stabil, aman, dan sesuai standar teknis, sehingga alat dapat digunakan dalam berbagai skenario kerja seperti bengkel, gudang, maupun lingkungan rumah tangga. Selain itu, mini crane ini dinilai lebih ekonomis dibandingkan dengan crane konvensional, karena desain yang sederhana, mudah dioperasikan, dan tidak membutuhkan operator dengan keterampilan khusus

Abstract

This study aims to analyze the effect of heat treatment on the hardness level of ST 37 steel material used in the press cage component, particularly after quenching using two different cooling media: seawater and SAE 40 oil. The press cage is a crucial component in screw press machines that operates under high pressure and requires optimal mechanical strength, including sufficient material hardness. The research method involved heating the specimens at 850°C for 30 minutes, followed by quenching using each of the cooling media. Hardness testing was conducted using the Rockwell method at five test points on each specimen. The results showed that the untreated specimen had an average hardness value of 72.3 HRC. After heat treatment and quenching, hardness significantly increased, with an average value of 93.8 HRC for specimens cooled in seawater and 84.3 HRC for those cooled in SAE 40 oil. The highest hardness was achieved using seawater due to its rapid cooling rate, which promotes the formation of martensitic structures. In contrast, quenching with SAE 40 oil produced lower hardness results because of its slower heat dissipation process. These findings indicate that the type of cooling medium has a significant impact on the mechanical properties of the material after heat treatment.
