Abstract

Jenis dan variasi sampah dapat menunjukkan jumlah dan tingkat perekonomian penghuninya. Tingginya timbulan dan variasi sampah sering menjadi masalah pada beberapa perumahan. Kondisi rumah yang berdekatan, lahan kosong yang sedikit, kondisi TPS yang terbuka serta pengelolaan sampah yang kurang menjadi permasalahan bagi penghuni yang tinggal di perumahan tersebut. Kondisi ini dapat menjadi penyebab munculnya penyakit, bau busuk, serta lingkungan yang tidak sedap dipandang. Berdasarkan hal tersebut, maka perlu dilakukan kegiatan penyuluhan. Kegiatan penyuluhan ini bermaksud untuk memberikan informasi tentang sampah hasil rumah tangga, jenis pengelolaan yang sesuai, serta hasil pengelolaan jika sampah tersebut dapat diolah dan menjadi income. Teknik yang digunakan pada kegiatan pengabdian ini adalah pendekatan persuasif dalam pemilahan, pewadahan, dan pengumpulan sampah dari sumbernya.

Abstract

Peat water is raw water which is used as a source of clean water by the people of Pekanbaru. However, after testing according to the Regulation of the Minister of Health of the Republic of Indonesia for clean water standards No. 416/MENKES/PER/IX/1990 the results of measuring the color and turbidity value of peat water are above the quality standards, namely 219 TCU and 15.1 NTU. This value is very far from the color and turbidity quality standards with respective concentrations of 15 TCU and 5 NTU. Therefore, in this research, an adsorption process was carried out using an adsorbent from Patin bone waste (Pangasius sp.) typical of Riau province by utilizing a physical activation process to open pores and help facilitate absorption. The variable used in this research were adsorbent mass and stirring speed. For adsorbent mass there was a variation of 0.1; 0.3; 0.5; and 0.7 grams while the stirring speed was 50, 100, and 150 rpm with a stirring time of 120 minutes and each sample had a particle size of 100 mesh. The results of this adsorption process obtain the best efficiency value at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm. The color reduction efficiency reached 96.35%, namely 8 TCU, while the turbidity reduction efficiency at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm reached 92.72%, namely 1.1 NTU.

Abstract

Electrinic Fuel Injection (EFI) a system that supplies fuel from the tank electronically with a mixture of air that suits fuel needs so that vehicle power remains maximum with minimal fuel consumption to produce environmentally friendly emissions. The fuel injection system is an innovation step that is being developed and applied to motor vehicles today. The purpose of the study was to find out the characteristics of the 2007 Honda Jazz I-DSI engine using the parameters of maximum torque, maximum power, average effective pressure (Brake Mean Effective Pressure) and specific fuel consumption (Specific Fuel Consumption). The method used is direct observation of the problems related to this study. Torque as the rotation of the Honda Jazz i-DSI engine shaft has a higher torque. This shows that the Honda Jazz engine has a higher torque value to improve engine performance. Effective engine power occurs at engine shaft revolutions of 1000 to 5000 rpm. The specific fuel consumption of the Honda Jazz engine has a higher specific fuel consumption value of 34.23% than the i-DSI with the PGM-FI (Programmed Fuel Injection) fuel supply system. At 3500 to 6000 rpm, the Honda Jazz i-DSI engine has a higher specific fuel consumption value compared to the PGM-FI fuel supply system. So the use of fuel using the i-DSI engine is more efficient at low revs because it uses 2 spark plugs, so combustion can be maximized. The thermis efficiency of the Honda Jazz i-DSI engine has a higher thermis efficiency value of 11.15%. Thermis efficiency rises when the engine revs up. Then it can be said that the efficiency of the thermis is directly proportional to the rotation of the engine.

Abstract

Salah satu penyebab blongnya rem adalah suhu pada rem yang melebihi batas maksimalnya, sehingga terjadi penurunan daya pengereman pada kampas rem. Tujuannya untuk mendapatkan temperatur kerja rem tromol. Metode yang digunakan adalah metode Research and Development. Hasil penelitian didapat temperatur rem sangat cepat mengalami peningkatan ketika suhunya dibawah 100oC dan ketika berada diatas 100oC peningkatan suhunya menurun. Rata-rata peningkatan temperatur rem tromol mulai dari 0,16oC/detik hingga mencapai 0,58oC/detik tergantung temperatur kerjanya. Penurunan temperatur rem ketika rem tidak ditekan didapatkan hasil bahwa rem sangat lambat turun temperaturnya. Pengujian rem membutuhkan waktu 22 menit untuk menurunkan temperatur 129,3oCmenjadi 83,9oC, tetapi ketika temperatur kerja rem berada diatas 200oC maka penurunannya juga sangat cepat. Disimpulkan bahwa saat melakukan pengereman, temperatur pada tromol water cooler brake lebih rendah dibandingkan tromol standard hingga 30%. Perbedaan temperatur antara tromol standard dan tromol water cooler brake semakin jauh selisihnya ketika temperatur kerja rem diatas 100oC.

Abstract

Supercapacitors are increasingly developing energy storage devices because they have advantages over conventional batteries and capacitors, such as high power density and long cycle life. Electrolytes are solutions that contain ions and function as electrically conductive media. In chemistry, electrolytes usually consist of acid, base, or salt solutions. The electrolyte used in supercapacitors plays a crucial role in achieving the desired power and energy density. In general, electrolytes are divided into two types based on their phase form, namely liquid and solid or gel electrolytes. Liquid electrolytes can be acids, bases or salts. While gel electrolytes are electrolytes that are denser in nature so that they can reduce leakage.
