Abstract

Heat absorb ability split AC is the most important factor in the cooling speed on room temperature. The rate of temperature drop is determined by many factors, including compressor power. Nowadays, there are many Split AC are produced that have low power (low Watt), so that research is needed to determine the cooling speed in a room. This study uses a low watt split AC with a power of 0.5 HP. The distance from the evaporator and the outside temperature are used as independent variables, while the rate of temperature reduction or cooling speed in the room is used as the dependent variable. The results showed that the distribution of room temperature and the rate of temperature reduction in the room varied based on the position of the distance to the location of the AC Split Low Watt. The lowest temperature and reduction rate in the room occurs at a distance of 2 m and 3 m in front of the AC location. The outside temperature or the temperature around the location of the AC condenser affects the temperature distribution at each distance in front of the AC. When the outside temperature is low, the temperature conditions at a distance of 1 m, 4 m, and 5 m have a significant difference. While the high outside temperature conditions, the temperature at a distance of 1 m, 4 m, and 5 m, namely the positions close to the wall, is almost the same.

Abstract

Kelurahan Tunjungsekar is one of District in Malang, which is located at center of town that it has rarely have a water absorbtion region so it is prone to flooding when it rains.  Through this PkM program, it is proposed a biopori production that serves as a water catchment area which can help the land or residental areas that have rarely trees to absorb water in a relatively short time so that no water flows or even floods occur.  The method of implementation of this program is to invite people to make biopori at some point which is prone to puddle. Some stages of the implementation of this biopori making program are: 1. The preparation stage, at this stage preparation of equitment and biopori media and site survey to determine which points need to be installed biopori. 2. Implementation phase, at this stage people do soil drilling and installation of biopori at some point location that has been predetermined. Reporting stage, at this stage will be reported the results of activities that have been implemented including details of the cost. The whole stages are conducted over a period of 8 months involving the role of the civilitation RT.09 RW.04 Kel. Tunjungsekar Kec. Lowokwaru Kota Malang.

Abstract

Bioethanol is an alternative fuel to substitute fossil oil. Bioethanol has several advantages in its use as a fuel in addition to its renewable nature, and bioethanol is also believed to reduce some motor vehicle emissions. The purpose and objective of this study were to determine the effect of a mixture of Bioethanol and Pertamax on gas emissions in a 4-stroke motor with variations in the fuel mixture and engine cycle. This test method is carried out with the measurement parameters of CO, HC, CO2, and O2. Tests on motor vehicles were carried out with variations of BP0 (0% Bioethanol) to BP100 (100% Bioethanol). The test results using a gas analyzer and analyzed using excel show that bioethanol cannot reduce exhaust gas emissions. Adding bioethanol fuel to Pertamax can also increase the fuel's octane number (RON) and specific gravity. From the available data, adding bioethanol can reduce HC emission levels by up to 4ppm at BP50 at 6000 rpm, increasing CO2 emissions by 13.4% at BP50 at 7000 rpm with a compression ratio of 13:1. For the lowest O2 emission level, it reaches 0.13%. at BP40 at 5000 rpm. CO emission levels are still relatively small in various mixtures with a yield of 0.01%, but at BP0 and BP80 at 13:1 compression, emissions tend to increase every rpm.

Cara ini dapat mengurangi polusi udara sehingga udara yang dihirup tidak terlalu bahaya bagi kesehatan. Metode penelitian yang di gunakan merupakan metode exprimen dengan pengolahan data menggunakan duo factorial yang mengetahui pengaruh variabel bebas terhadap variabel terikat yang di tentukan. Penambahan Octane booster cair kedalam bahan bakar shell super berpengaruh terhadap nilai emisi gas buang HC,CO dan CO2 pada kendaraan Innova. kesimpulan bahwa dengan campuran sebanyak 2,5% meghasilkan gas HC terendah dan yang tertinggi di hasilkan oleh campuran 1,6%. Kadar emisi gas buang CO dengan campuran 2,5% menghasilkan gas CO yang terendah dan campuran 1,6% octane booster menghasilkan CO tertinggi. Kadar emisi gas CO2 yang terkecil dihasilkan oleh bahan bakar shell super murni tanpa campuran sedangkan CO2 terbesar dihasilkan oleh campuran 3% octane booster cair.

Abstract

Perkembangan teknologi di bidang otomotif mendorong masyarakat untuk menciptakan berbagai inovasi salah satunya alat transportasi yaitu kendaraan Multi Purpose Vehicle (MPV). Tujuan penelitian ini yaitu untuk mengetahui apakah ada pengaruh yang signifikan dengan dilakukannya kalibrasi atau  remapping ECU standar pabrikan terhadap torsi pada motor bensin 4 silinder 2000 cm3.Penelitian ini menggunakan metode desain eksperimental. Variabel bebas dalam penelitian ini adalah remapping sudut pengapian (std, std +2˚, std +4˚) dan durasi injeksi (std, std +2 Ms, std +4 Ms). Hasil penelitian diperoleh nilai sudut pengapian std +2˚ dan durasi injeksi std +2 Ms merupakan variasi yang menghasilkan torsi paling optimal yaitu sebesar 176 Nm. Pada sudut pengapian std +4˚ dan durasi injeksi std +2 Ms; sudut pengapian std +2˚ dan durasi injeksi std +4Ms; sudut pengapian std +4˚ dan durasi injeksi std +4 Ms, nilai torsi yang dihasilkan cenderung menurun.
