Abstract

Saat ini jagung menjadi komoditi tanaman pangan yang dibudidayakan oleh kelompok tani di Kecamatan Dramaga, Bogor, Jawa Barat. Pada proses tanam jagung, upah untuk pekerja dan jasa pertanian lainnya adalah komponen biaya produksi paling besar yang harus dikeluarkan para petani per musim tanam untuk satu hektar luas panen jagung. Perbandingannya mencapai 54% dari total biaya produksi yang harus dikeluarkan. Hal ini disebabkan oleh beberapa faktor diantaranya belum adanya suatu alat yang membantu petani dalam proses tanam jagung yang praktis, sehingga diperlukan banyak pekerja dan tenaga dalam prosesnya seperti pembuatan lubang tanam, penjatuhan benih, proses penutupan lubang tanam, serta perataan lubang tanam yang seluruhnya masih dilakukan secara manual. Cara ini dirasa petani membutuhkan banyak tenaga, biaya produksi yang tinggi, serta kurang efisien. Berdasarkan permasalahan tersebut, maka kami membuat alat tanam jagung yang praktis dan efisien di mana seluruh proses tanam jagung hanya dilakukan menggunakan satu mekanisme kerja pada alat. Dengan menggunakan alat ini membuat Kelompok Tani Jagung di Dramaga, Bogor menjadi sangat terbantu, pekerjaan petani menjadi lebih ringan, kualitas tanam lebih baik dan presisi, waktu yang dibutuhkan menjadi lebih singkat, tenaga yang dibutuhkan menjadi lebih sedikit, serta lebih praktis digunakan sehingga dapat mengurangi biaya produksi (upah pekerja dan biaya produksi lainnya).

Abstract

Struvite or Magnesium Ammonium Phosphate Hexahydrate (MgNH4 PO4.6H2O) is one of the precipitates generally formed in the piping system. The formation of struvite in the piping system is one of the serious problems that can cause blockages, reduced flow volume, and pipe diameter to increase maintenance and production costs. This formation of struvite scale in the industrial instrument is detrimental; however, struvite can be used as raw material for slow-release fertilizers. This study will observe the effect of pH in the range of 8, 8.5, 9, 9.5, and 10 on the formation of struvite compositions, consisting of Mg, NH4, PO4, Ca, and K in the surrounding temperature of 35oC. The results of this study will be observed using visual MINTEQ software. The result shows that the most suitable pH for struvite formation is 9.5.

Abstract

The dependence of Indonesian people on diesel fuel is still very high, proven by the increasing amount of diesel fuel consumption yearly. The increase in diesel fuel consumption is a severe problem that must be anticipated because diesel is a fuel that originates from fossils and is non-renewable. In addition to its limited availability, environmental issues are also a matter of concern in the use of diesel fuel because the resulting exhaust emissions can interfere with health and increase global warming. One way to overcome this is to switch from fossil fuels to biofuels, i.e., biodiesel. Although theoretically biodiesel can be used directly as a substitute for diesel fuel, there is very little research on the fuel consumption required for the exhaust emissions produced. Therefore this study aims to determine the correlation between the characteristics of specific fuel consumption (SFC) on exhaust emissions produced in diesel engines using B20 (20% biodiesel + 80% diesel) and B100 (100% biodiesel) fuel. Based on the results of the study, it was found that an increase in SFC resulted in a downward trend in carbon monoxide (CO) and carbon dioxide (CO2) emissions. In the meantime, the hydrocarbon (HC) emissions and the resulting smoke opacity increased; this was influenced by several factors such as an increase in combustion temperature, increased deposit, and component wear.

Abstract

The electrolysis of water is one of many methods to produce hydrogen by converting electrical and thermal energy into hydrogen and oxygen. In this study, a generator of the HHO dry cell type is used to produce brown gas. Brown’s gas consists of two hydrogens and one oxygen or Oxyhydrogen (HHO). Observation will be conducted to obtain the effect of electrode gap distance to increase the productivity of Brown’s Gas with a mixture of 2500 ml pure water and catalyst of NaHCO3. The results show that if the electrode gap is small, it will produce more brown gas than the long gap. However, research still needs to be done on how close the electrode gap distance is needed to produce maximum brown gas.

Abstract

Until now, the need for revision surgery and implant failure is still the main clinical problem in installing biomaterials in the human body. Mechanical testing is needed to determine the life of the biomaterial before it is implanted in the human body. Mechanical testing in this study was carried out using a pin on discs simulator, run for 50000 cycles in dry condition. PCU material is used as disc components and SS 316L as a pin. The following test parameters were used: normal load FN = 500 gram and sliding velocity 50 Rpm in dry condition. Chemical changes in the wear scar can cause a drift in friction level. This study aims to analyze the chemical surface changes in wear tracks of PCU after mechanical testing. For this, Raman spectroscopy was used to determine the chemical changes at the surfaces. The wear tracks developing between the metal on PCU were analyzed using these techniques. The results show that the chemical changes in the wear scars of the PCU disc are due to mechanical stress. Raman spectroscopy is used to observe the chemical changes on the wear scar due to the sliding test.

Abstract

Indonesia is one of the largest palm oil-producing countries globally, with a production value of 40 million tons by 2020. Biodiesel is one of the alternative energy sources that can be processed from palm oil. Diesel engines can directly use biodiesel as a fuel. Biodiesel has distinct characteristics from diesel; thus, it will affect performance and other things on the engine. In this research, diesel engine performance tests were carried out, including specific fuel consumption (SFC), cylinder head temperature, cylinder block, and exhaust pipe, with a test time of 300 hours. This research aims to determine the effect of the cylinder head, cylinder block, and exhaust pipe temperatures on SFC using two different fuels, i.e., B100 and B20. Based on the test results, the average cylinder head, cylinder block, and exhaust pipe temperatures on the B100 engine are 136 oC, 130 oC, and 257 oC. As for the B20 engine's cylinder head, block, and exhaust pipe temperatures are 139 oC, 132 oC, and 264 oC. Engine with B100 fuel obtained SFC of 0.317 kg/kW.hour and engine with B20 fuel obtained SFC of 0.276 kg/kW.hour. In general, the combustion temperature in the cylinder head affects the increase in SFC in both engines with different fuels; the higher the combustion temperature in the cylinder head, the higher the SFC is. Engines with B100 fuel have a higher SFC value than B20 fuel, which is influenced by the higher viscosity and density values; thus, the droplets from the fuel atomization process become larger when compared to fuels with lower viscosity and density values. The graph analysis shows that the cylinder block temperature graph on the B100 and B20 fueled engines decreases between temperatures of 133-134 oC, then inflates with the increase in specific fuel consumption. The higher temperature compared to the B100 fuel engine makes the fuel undergo complete combustion when injected into the combustion chamber due to atomization or very fine droplets burning completely. The cylinder block temperature chart on the B100 and B20 fueled engines has a very significant trend difference. B100 engines tend to experience a decreasing trend in temperature along with an increase in SFC, while B20 engines tend to experience an increasing temperature trend along with an increase in SFC.
