Abstract

Consumption of fuel oil (BBM) at a fishing port is usually much influenced by the number of ships and what types of fishing vessels are actively operating in the fishing port. The more the number of fishing vessels operating, the more the amount of fuel oil (BBM) needed and vice versa. Basically the number of fishing vessels operating depends on the fishing season. The type of fishing vessel also affects the characteristics of fishing vessels, such as trip time and fishing ground area. The role of diesel fuel is very important for capture fisheries activities, especially to support the operation of each ship with purse seine fishing gear available at PT. Batam True Sea Products. One of them is KM. Fortuna. The making of this report aims to calculate the amount of solar demand that exists on KM. Fortuna. Field research was conducted for approximately 25 days. Primary data were collected through observations and interviews with 1 engine room head (KKM) and 1 crew member in the engine section of the KM. Fortuna Secondary data obtained directly from PT. True Sea Products. Diesel fuel for the needs of purse seine ships in the port usually depends on the size, type, and length of time the ship operates at sea, for KM vessels. Fortuna was given a supply of diesel fuel per sail of 12,941,181 liters or 11 tons.

Abstract

The increasing human population, the use of fossil energy such as oil also increases. While fossil energy is one of the largest contributors to carbon emissions that can cause climate change that can be done to control climate change is to switch to the use of renewable energy. The investigation takes the shape of a vertical axis Savonius turbine blade design. The blades are made of a composite material called carbon fiber, and the number of blades varies between 4, 6, and 8 pieces. The study's findings were tested utilizing a blower-generated wind source with wind speeds of 4m/s, 4.5m/s, and 5m/s. A wind tunnel consisting of acrylic material and pipes as a frame construction was used in the test. The test findings show that turbine blades with a total of four blades produce the maximum generator power of 0.274 watts at a wind speed of 5 m/s. Meanwhile, the turbine blade with 8 blades has the lowest output power at a wind speed of 4 m/s and a power value of 0.0028 W. Then, with 8 blades, it has a relatively low output energy compared to 4 and 6 blades. Therefore, the highest efficiency performance of wind turbine use is achieved by a turbine with a number of 4 blades with a maximum efficiency is 9,16% and the minimum efficiency it seen in a wind turbine with a number of blades 8 within 0,07%.

Abstract

Penelitian komposit matrik logam aluminium yang diperkuat dengan keramik menggunakan metode metalurgi serbuk akhir-akhir ini semakin banyak diminati untuk dikembangkan. Tujuan penelitian ini adalah untuk mengetahui pengaruh perbedaan tekanan kompaksi terhadap sifat densitas dan sifat kekerasan komposit yang dihasilkan. Metode penelitian yang digunakan adalah mengikuti tahapan proses metalurgi serbuk, yaitu meliputi persiapan material, pencampuran dan kompaksi. Pencampuran serbuk penyusun komposit dilakukan dengan metode mechanical alloying atau pemaduan mekanik menggunakan mesin horizontal ball mill selama 4 jam. Sedangkan metode kompaksi panas yang digunakan adalah kompaksi dua-arah penekanan, menggunakan mesin pompa hidrolik. Material matriks yang digunakan adalah serbuk aluminium hasil daur ulang, dan material penguat digunakan serbuk dari pasir silika tailing tambang timah. Proses kompaksi panas dilakukan pada suhu 500 0C ditahan selama 15 menit. Variasi tekanan kompaksi dua-arah digunakan 4400 PSi, 4500 PSi dan 4600 Psi. Pengujian densitas mengacu Archimedes dengan stradar ASTM B962-17. Sedangkan pengujian kekerasan digunakan mesin uji kekerasan Brinell, mengacu pada standar ASTM E110-14. Hasil uji densitas dan uji kekerasan menujukkan kecenderungan nilai semakin meningkat dengan meningkatnya tekanan kompaksi yang diaplikasikan. Densitas tertinggi adalah 2,147 g/cm3 untuk sampel dengan kompaksi sebesar 4.600 Psi, dengan nilai kekerasan tertitinggi adalah 53,11 HRB. Berdasarkan foto mikro menunjukkan bahwa ikatan mekanik interlocking pada tekanan kompaksi yang lebih rendah cenderung lemah, patahan pada batas butir kelihatan jelas dan pola kerusakannya cenderung menunjukkan patahan rapuh/getas.

Abstract

Metal cutting is the stage of processing profile raw materials and steel plates according to the cut marks that have been set in the marking process. One of the metal cutting techniques is to use oxy acetylene welding where the cutting occurs due to the reaction of oxygen and steel. Oxy acetylene welding is a manual cutting and welding process, in which the surfaces to be joined are heated until melted by the flame of acetylene gas, namely burning C₂H₂ with O₂ with filler metal or without filler metal where the joining process is without pressure. Besides for welding purposes (connection), oxy acetylene welding can also be used as preheating, brazing, cutting and hard facing. In the process of cutting iron pipes using oxy acetylene welding manually, the problem that is often found is the results of uneven and not straight cuts. This causes a leveling process to be needed on the edges that are cut so that they are flat and straight. In this research, a pipe cutting machine with oxy acetylene welding has been made which aims to produce straight, smooth, and even pipe cutting. The pipe cutting machine that has been made can produce flat, smooth, and straight iron pipe cuts on iron pipes with a diameter of 4.5 inches, 3.5 inches and 3 inches with a cutting time of 32 seconds, a motor wave rotation speed of 5.8 Hz, and a cut tolerance of ± 3 mm.

Abstract

The main contributor to the problem of slum settlements in urban areas is the issue of waste. Waste management that does not comply with the technical requirements encourages local governments to build TPS3R in residential areas. TPS3R KSM Kawa Begawe in Selindung Village is one of the real works of collaboration between the local government and the central government. TPS3R was founded in 2016 and developed in 2022 by providing organic and inorganic chopping machines, hydraulic press machines and maggot feed pulping machines. The purpose of this research is to find out whether this machine has been used optimally and has been able to improve the community's economy. The method used is a mixed method, where quantitative data is analyzed using simple calculations and qualitative data is analyzed using descriptive analysis. The results of the analysis found that as the population increases, TPS3R is urgently needed as an effort to reduce waste production by reducing disposable items or processing waste into other useful products and can open up new job vacancies so that it eventually becomes a source of income for the local community. In terms of the economic development plan, when this machine has been used optimally, this place will become a qualified source of income for the local community. The results of this study are certainly proof that TPS3R does not only answer the problem of environmental pollution caused by waste, but can also produce products that have economic value from waste processed at TPS3R KSM Kawa Begawe.
