Abstract

Setelah berakhirnya masa pandemi covid-19, terjadi pertumbuhan ekonomi di Kalimantan Selatan khususnya di sektor pariwisata pendakian gunung. Begitu pesatnya peningkatan jumlah pendaki gunung mendorong peningkatan kebutuhan bagi para pendaki. Kebutuhan tersebut adalah energi cahaya untuk penerangan, energi gerak untuk kipas dan lain-lain. Untuk itu, dibutuhkan alat yang bersifat mobile. Melihat fenomena diatas, maka penulis melakukan perancangan microdiesel dengan daya 0,7 HP. Prinsip kerja microdiesel seperti motor diesel dua langkah pada umumnya. Hanya saja tidak terdapat flywheel pada microdiesel namun ujung sisi crankshaft yang terhubung dengan conrod langsung ditutup dengan backplate. Desain alat ini tidak membutuhkan tempat yang luas serta mudah dibongkar pasang dan mudah dipindahkan. Alat ini menggunakan solar sebagai bahan bakar, dan menghasilkan gas buang seperti halnya motor diesel. Hasil perhitungan perancangan adalah diameter/langkah yaitu 33x33 mm, kapasitas engine 7 cc, perbandingan kompresi 13:1, max putaran yaitu 2500 rpm dan massa alat 1,2 kg dengan AJ14 dan SiCr sebagai material pembentuk. After the Covid-19 pandemic is over, economic growth occurred in South Kalimantan, especially in the mountaineering tourism sector. Along with the increase in travelers, the equipment and needs for climbing will also increase. The needs and equipment are light energy for lighting, motion energy for fans and others. For that, we need a tool that is mobile. Seeing the phenomenon above, the authors designed a microdiesel with a power of 0.7 HP. This tool works like a two-stroke diesel engine. In this tool, the flywheel is not attached, but the crankshaft which is connected to the conrod is directly connected to the backplate. This tool is mobile and interchangeable. The results of the design calculations are the diameter/step of 33x33 mm, the engine capacity is 7 cc, the compression ratio is 13:1, the max rotation is 2500 rpm and the tool mass is 1.2 kg with AJ14 and SiCr as forming materials.

Abstract

Heat exchanger pada proses pengolahan air limbah PT. Andalan Furnindo sering bermasalah. Oleh sebab itu, penulis mencoba untuk memodifikasi desain heat exchanger pada bagian tube, baffle, dan estimasi pressure drop agar mendapat performa yang lebih bagus. Proses pengolahan data dimulai dari memodifikasi dimensi diameter shell, diameter tube, panjang shell, panjang tube, jumlah baffles, jumlah tube dan jenis path aliran fluida. Menghubungkan  korelasi antara parameter dengan modifikasi dimensi yang telah dilakukan agar hasil akhir berupa nilai koefisien perpindahan panas dan pressure drop sesuai yang diinginkan. Hasil perhitungan perancangan dengan  Dsid =1 m; di = 0,02 m; do = 0,025 m; panjang shell dan tube=4,6 m; B=5; Nt=1176 dan path aliran U adalah menghasilkan Uc=683  dan Uf=569 ; =1691,3 Pa; dan =1276,6 Pa. Dengan memodifikasi diameter tube dan shell yang lebih besar dari setelan pabriknya dapat memudahkan proses perawatan unit dalam hal membersihkan kotoran dalam tube maupun dalam shell. Sehingga performanya stabil, umur pemakaian unit lebih lama, dan waktu perawatan selanjutnya terjadwal dengan baik. Heat exchanger in the waste water treatment process of PT. Andalan Furnindo is frequently in trouble. Therefore, the authors try to modify the heat exchanger design on the tube, baffle, and estimated pressure drop in order to get better performance. The data processing starts from modifying the dimensions of shell diameter, tube diameter, shell length, tube length, number of baffles, number of tubes and type of fluid flow path. Linking the correlation between parameters with dimensional modifications that have been done so that the final result is the value of the heat transfer coefficient and pressure drop as desired. The results of design calculations with Dsid =1 m; di = 0,02 m; do = 0,025 m; length of shell and tube = 4.6 m; B=5; Nt=1176 and the flow path U is to produce Uc=683  dan Uf=569 ; =1691,3 Pa; dan =1276,6 Pa. By modifying the tube and shell diameter which is larger than the factory setting, it can facilitate the unit maintenance process in terms of cleaning dirt in the tube and in the shell. So that the performance is stable, the service life of the unit is longer, and the next maintenance time is properly scheduled.

Abstract

Melalui kebijakan Pemerintah Indonesia dalam mencapai ketahanan pangan dalam negeri maka kegiatan dibidang pertanian dan perkebunan kembali dilirik oleh para peneliti untuk meningkatkan hasil produksi pertanian dan perkebunan. Beberapa upaya dalam mendukung peningkatan produksi pertanian dan perkebunan diantara yaitu menghasilkan sebuah alat yang membantu/mempermudah dalam proses kegiatan produksi. Penelitian ini bertujuan untuk merancang dan mengetahui performa dari sebuah mixer pengaduk pupuk organik cair (POC) yang nantinya akan digunakan di Desa Masingai II Kabupaten Tabalong oleh para kelompok tani. Pada penelitian ini menggunakan metode experimental pada mesin POC yang dibuat. Hasil penelitian menunjukkan mesin bekerja secara optimal dengan penggunaan daya 426 W yang menghasilkan putaran 66 rpm dengan konsumsi listrik sebesar 0,0007 kWh dengan kapasitas yang diaduk hingga 200 liter. Through the Indonesian Government's policy to create food security and improve farmers' welfare, researchers are looking at agricultural and plantation activities again to increase agricultural and plantation production. Some efforts to support increased agricultural and plantation production include producing a tool that helps/makes the production process easier. The purpose of this study is to design and calculate the performance of liquid organic fertilizer (POC) mixers which will later be used in Masingai II Village, Tabalong Regency by farmer groups. Experimental methods were used in the study. The research results show that the machine works optimally using 426 W of power which produces 66 rpm rotation with an electricity consumption of 0.0007 kWh every minute.

Abstract

The aim of this research was to investigate the different impacts of compression pressure on power and torque outputs using gasoline RON 92, RON 95, and RON 100. The study involved experiments using a single-cylinder motorcycle engine with a capacity of 125 cm. The selection of this type of engine is based on the popularity of vehicles in Indonesia that use a single-cylinder engine with a capacity of 125 cm. To modify the compression pressure, variations in the number of gaskets were applied to the cylinder head, with quantities of 1 and 3 gaskets. Dynamometer tests were conducted to measure the engine's performance differences. Throughout the testing, the settings for the main jet, pilot jet, and the number of idle screw rotations on the carburetor remain constant. The findings indicate that the engine with the highest compression pressure of 11.8 Kg/cm, using RON 100 gasoline, produces the highest power output at 7.9 kW, with the highest torque at 10 Nm.

Abstract

The total motor vehicle sales reflected an increase in people's mobility. Alongside this, the industry were also develop high compression engines to achieve optimal performance. This research aims to examine the effects of adding a cylinder head gasket and variations in the octane number of gasoline used in a single-cylinder internal combustion engine. Dynamometer testing was conducted to observe the differences in torque and power output. The test results indicate that an engine with a compression ratio of 11,8 Kg/cm2, coupled with the use of RON 100 gasoline, produces the highest power output, which is 7.90 kW, with peak torque reaching 9.93 Nm. On the other hand, the smallest torque is generated by the same engine when supplied with RON 92 gasoline, at 4.78 Nm, with the lowest power output of 5.43 kW.
