Abstract

The Cat 16M Grader is a heavy equipment that is widely used to support mining operations. The development of this heavy equipment is required to use biodesel fuel (B30). The problem with B30 fuel is oxidation which results in the formation of sediment and can cause filter clogging. Filter clogging can affect engine power and filter replacement time. From these problems, the researcher proposed to modify the number of sediment separator core holes to reduce the filter clogging rate on the Cat 16M grader. Modified number of sediment separator core holes are 40, 20 and 10 holes with 8 mm hole dimension. Data was collected experimentally by implementing the modified sediment separator core on a Cat 16M grader for 250 hours of operation. The research resulted in the number of sediment separator core holes 10 at 250 hours of operation producing the highest sediment volume of 92 ml, the filter with the lowest clogging rate and the lowest fuel pressure difference. In addition, using the number of sediment separator cores 10 at 250 hours of operation produces the highest engine power, the highest filter clogging efficiency and has a high economic value.

Abstract

The solar radiation heat absorbing plate is a major component in solar still applications. The fin absorber plate with mortar material as a heat absorber, heat transfer, and evaporation medium. In the fin absorber plate with mortar material, seawater flows inside the fin body capillarity and undergoes an evaporation process, leaving salt in the pores. Salt in the pores, type, and dimension of sand as the main forming material of mortar will also affect the effective heat conductivity value. This study evaluates salt formation in the pores with various types and dimensions of sand-forming mortar material on effective heat conductivity. The research was conducted experimentally by comparing the types and dimensions of sand-forming mortar. The types of sand used were iron sand (PB) and lichen sand (PL), with sand dimensions of 0.125 and 0.250, respectively. The types and dimensions of sand were formed into mortar with a mixture of 2 sand and one cement. The mortar test was compared with stone material. In the test, heating was applied to the top surface of the mortar and stone using a heating element (heater) with 46.4 W power for 120 minutes. The research resulted in the effective heat conductivity of all mortar materials increasing with increasing heating time and salt in the pores. The mortar material using iron sand with a dimension of 0.125 mm (PB.0.125) has a higher total effective heat conductivity of 0.712 (W/m0C) than PB.0.250, PL.0.125, PL.0.250 and stone.

Abstract

Ngadireso Village, Poncokusumo District, has a water source from Umbulan Spring with a discharge of 1 m3/minute located in Ngadireso Hamlet, Ngadireso Village. The water needs of the residents of Ngadireso Village depend on the Umbulan water source. The location of residents' homes is above the source so that to pump water using an electric pump with electricity costs of ± Rp. 11,000,000, - every month. There were already 3 hydraulic pumps available before to help reduce the cost of electric pumps, but 2 ramp pumps were damaged so it was necessary to hold a hydraulic pump update. Ramp pumps are used to drain water to the main reservoir. With this hydraulic pump, the monthly contribution of residents for electricity pump payments decreases by 2 million every month, so monthly contributions also decrease.ABSTRAKDesa Ngadireso Kec. Poncokusumo memiliki sumber air dari mata air Umbulan dengan debit air sebesar 1 m3/menit yang berada di Dusun Ngadireso Desa Ngadireso. Sumber air Umbulan adalah satu-satunya sumber untuk memenuhi kebutuhan air warga desa.  Lokasi rumah warga berada di atas sumber sehingga untuk manaikkan air menggunakan pompa listrik dengan pembiayaan sebesar Rp. 11.000.000,- setiap bulannya. Sudah tersedia tiga pompa hidram sebelumnya untuk membantu mengurangi biaya pompa listrik, namun terdapat kerusakan pada dua pompa hidram sehingga perlu diadakan pembaruan pompa hidram. Pompa hidram  digunakan untuk memompa air dari sumber umbulan ke tandon utama. Dengan adanya pompa hidram ini maka iuran bulanan warga untuk pembayaran pompa listrik menurun sebesar 2 juta setiap bulan, sehingga iuran bulanan juga ikut menurun.
