Abstract

Plastic is a material that is widely used in modern society. You can see products made from plastic, ranging from toys, kitchen utensils, electronics to toothbrushes that are used every day. Plastics are widely used because of the advantages of plastic which is strong, lightweight, easy to form, is a good insulator, non-corrosive and durable. Currently, based on statistical data on Indonesia's domestic solid waste, plastic waste ranks second, namely 64 million tons per year or 14% of total waste production. This large consumption is not matched by the same amount of recycling. Plastic waste can cause problems for the environment because it is very difficult to decompose. The time to decompose plastic waste naturally takes approximately eighty years to completely degrade. Therefore, designing and making a plastic waste sorting tool that uses a waterwheel and koveyor working system, where later when this design has been applied and functions properly it can be useful for sorting plastic waste. When this tool is functional it will be very helpful in the environment of landfills and other places.

Abstract

AbstrakPenggunaan sistim pendingin berbasis kompresor yang meluas telah memicu peningkatan kerusakan lingkungan dan penggunaan energy bahan bakar fosil yang berlebihan. Sistim pendingin evaporative merupakan salah satu sistim pendingin alternative yang ramah lingkungan dan hemat energi, karena hanya memanfaatkan air dan udara sebagai daya penggerak sistim. Dalam penelitian ini ditujukan untuk menguji pengaruh variasi temperature air material pad terhadap sistim direct evaporative cooling (DEC) berbasis jerami padi dan tapis kelapa sebagai material pad. Pengujian dilakukan dengan pengaturan putaran fan pada 1440; 1470; dan 1500 rpm dan variasi temperature air pembasah pad pada 10oC dan 15oC dengan waktu pengujian selama 60 menit. Temperature udara masuk dan keluar pad dicatat sebagai TdB2,TwB2 dan TdB3,TwB3 secara berurutan. Dari hasil pengujian ditemukan bahwa kapasitas pendinginan tertinggi dengan material pad jerami pada putaran fan 1500 rpm dan temperature air pembasah 15oC tercapai sebesar 0.42 kW, untuk temperature air 10oC hanya tercapai 0.14 kW. Sedangkan dengan material pad tapis kelapa, kapasitas pendinginan tertinggi dicapai pada putaran fan 1500 rpm dan temperature air pembasah 15oC sebesar 0.56 kW, dan untuk temperature air 10oC didapat kapasitas pendinginan hanya sebesar 0.39 kW. Dari hasil pengujian tersebut diatas dapat disimpulkan bahwa dengan lebih tingginya temperature air pada permukaan material pad, akan mempercepat proses penguapan dan lebih banyak panas yang dapat diserap, sehingga kapasitas pendinginan menjadi lebih besar.Kata kunci : direct evaporative cooling, kapasitas pendinginan, temperature air pembasah pad, jerami, tapis kelapa.

This study aims to design and test the citronella leaf distillation tool by conducting experiments and testing the tools and test results. The parameters observed were heat transfer in the citronella leaf distillery produced by the tool, the results of the conduction heat transfer research in the distillation tank were 1,032.61 J/s (Joules per second) and heat transfer by natural convection in the distillation tank was 3,761.16 J/s (Joules per second) with an initial water temperature of 28°C to a specified temperature of 98°C. The distillation time of more than 5 hours will reduce the quality of the yield which is not up to standard. The effect of the part of lemongrass which produces a high yield percentage is on the leaves, while the high quality of citronella oil is on the leaves. % citronella citronella on fresh leaves was 67.36%, withered leaves were 44.92%.

Abstract

Hardening pada baja AISI-4120 dilakukan dengan tahapan berupa pemanasan sampai temperatur tertentu, holding time pada temperatur konstan sampai beberapa saat, dan pendinginan menggunakan media cair agar terjadi penurunan temperatur secara cepat. Pada penelitian ini variasi yang dilakukan adalah holding time, yaitu selama 10 menit, 20 menit, dan 30 menit. Uji yang dilakukan berupa uji kekerasan dan struktur mikro. Temperatur tungku pemanas adalah 8500C, media pendingin adalah air, pengujian kekerasan menggunakan Vickers, dan pengujian struktur mikro menggunakan mikroskop optik metalografi dengan perbesaran 1000X. Hasil penelitian menunjukkan nilai kekerasan paling tinggi terdapat pada benda uji dengan variasi holding time 30 menit sebesar 623 HVN. Untuk hasil pengujian mikrostruktur terdapat struktur berupa martensit dan bainit, persentase martensit pada benda uji dengan variasi waktu penahanan 30 menit yaitu 97%. Semakin lama holding time maka nilai kekerasan dan persentase mikrostruktur martensit yang terbentuk akan semakin meningkat.

Abstract

Heat Treatment is a process of heating a material (metal) with a certain temperature and then cooling it using certain media (for example: oil, water, and salt water) with a specified cooling speed. This research used a quenching and tempering heat treatment process on API 5L carbon steel pipe with a diameter of 16 inches (406.4 mm) and a pipe thickness of 1,437 inches (36.5 mm), which previously the carbon steel pipe had an overlay welding process on the inside using UNS N06625 filler metal with protective gas of Argon 99.999% to reduce the corrosion rate along the bending process to become Clad Bend Pipe. The purpose of this study is to find out any effects of heat treatment (Quenching and Tempering) to increase the value of the tensile test results on clad bend pipes.

The purpose of this research is to design and manufacture tensile test equipment that can determine the tensile load of natural fibers which is a parameter to determine the mechanical property of the material. The research method is to make designs through Autodesk Fusion 360 software, manufacture and supply components, assembling and test fiber tensile test equipment. In single fiber testing, the test specimen is made according to the ASTM ASTM 3379-02 standard. The results of this research are one unit of digital fiber tensile test equipment with a maximum load capacity of 100 N (10 kgf), a gripping capacity of 600 mm x 30 mm. While testing this fiber tensile test equipment on coconut single fiber material, the tensile strength (F) is between 16.42 N to 29.31 N. And from the calculation of tensile strength (σ) the tensile strength of coconut fiber is 61.70 N/mm2 to 83.80 N/mm2. From the results of this study, it was concluded that the tensile test equipment made can operate as expected to determine the tensile load (F) as well as single so that through the test results this tool can be determined the tensile strength of single fiber material.

Abstract

Tension Leg Platform (TLP) is an offshore platform that is usually used for oil and gas exploration activities in the deep sea. One of the problems is the extra shaking of the TLP in response to extreme ocean waves. Under certain conditions, especially in the deep seas of the ocean, these shocks can cause various disturbances, and even have the potential to damage structures. In this article, it is proposed to use a cylindrical pontoon to obtain a more stable dynamic response, which will then be compared with a pontoon with a square section which is commonly used so far. The dynamic response of both models was recorded by ultrasonic sensor and video tracker. The measurement results are displayed in a non-dimensional form, which is commonly known as the Response Amplitude Operator (RAO), which is the ratio between the displacement of the TLP to the wavelength. From this research, it was found that TLP with cylindrical pontoon section has a relatively stable response when compared to TLP with square pontoon section.

ABSTRACT The process of peeling garlic skin can be done manually or using a machine. In the previous garlic peeler machine using a 0.5 hp electric motor, dimensions of 750 mm x 500 mm x 750 mm, using a pulley and belt to reduce rotation to 100 rpm. The results of previous studies obtained a machine production capacity of 2.06 kg/hour and a machine production efficiency of 86%. Disadvantages of previous machines include: the dimensions of the peeler tube are small, only effective for 1000 grams, slips occur frequently on the pulley, the rotational speed of the peeler shaft cannot be changed. Modifications were made to the engine parts, including: increasing the dimensions of the stripper tube, varying the stripper tube, using a gearbox to transmit rotation, using 0.25 hp of power, and adding a dimmer to control the rotation. The modified engine has dimensions of 970 mm x 500 mm x 800 mm and the peeler tube rotation speed is 120 rpm. The results showed that the machine's production capacity for the peeler tube type without agitator was 2.88 kg/hour with the machine's production efficiency of 58.6%. The machine's production capacity for tube type with rubber stirrer is 1.2198 kg/hour, the machine's production efficiency is 47%.
