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

Persaingan dunia kerja yang semakin ketat dan jumlah lapangan pekerjaan yang terbatas menuntut SDM berkualitas tinggi agar mampu bersaing secara nasional maupun global. Pendidikan vokasi memiliki peran melahirkan siswa dengan keahlian tinggi yang ditunjang berbagai kompetensi yang sesuai dengan perkembangan dunia industri. Salah satu kompetensi keahlian di SMK Turen Kabupaten Malang adalah program pendidikan keahlian Teknik Permesinan. Penggunaan software untuk keperluan gambar teknik yang biasa digunakan di Industri seperti Solidworks yang menawarkan banyak fitur desain/ perancangan serta dilengkapi fitur simulasi gerak, mechanical, simulation dsb. masih belum banyak diketahui oleh tenaga pengajar. Prodi Teknik Mesin UPNVJT turut serta mengambil andil dalam pengembangan SDM Indonesia melalui skema pengabdian masyarakat di LPPM UPNVJT yaitu Pemanfaatan IPTEKS Bagi Masyarakat (PIKAT). Tujuan dari kegiatan ini adalah untuk menyelenggarakan pelatihan kepada tenaga pengajar di SMK Turen Kabupaten Malang untuk membantu meningkatkan kompetensi pada bidang desain, perancangan dan simulasi. Metode yang dipakai pada kegiatan ini adalah pelatihan dalam bentuk workshop dan praktikum dengan project base learning. Pelatihan ini memiliki target peningkatan kemampuan tenaga pengajar dalam bidang desain dan perancangan khususnya pada simulasi pembebanan statis, sehingga kedepannya dapat dijadikan materi dalam kurikulum pembelajaran di SMK Turen Malang. Berdasarkan kegiatan pelatihan yang telah dijalankan maka didapatkan hasil berupa peningkatan pengetahuan dari guru-guru di SMK Turen Malang terkait dengan penggunaan software Solidworks baik untuk kebutuhan desain maupun simulasi.

Abstract

CV. Tiga Lima Jaya selaku mitra merupakan industri yang bergerak dalam bidang pupuk organik di Kabupaten Trenggalek. Pupuk organik produksi CV. Tiga Lima Jaya telah dipasarkan dan digunakan oleh petani di Trenggalek dan sekitarnya serta dinilai dapat menghasilkan panen yang baik. Kapasitas produksi sekitar 15ton setiap bulan. Dengan hasil produksi tersebut, CV. Tiga Lima Jaya masih mengalami permasalahan kekurangan kapasitas produksi jika dibandingkan dengan permintaan pasar yang terus meningkat. Hal ini dikarenakan terkendala peralatan produksi yang kurang memadai. Tujuan dari program pengabdian ini adalah untuk meningkatkan kapasitas produksi pupuk organik CV. Tiga Lima Jaya. Metode yang digunakan dalam menyelesaikan permasalahan ini adalah dengan hilirisasi teknologi penghancur KOHE dan pelatihan pengoperasian dan perawatan alat. Setelah kegiatan berlangsung, dinyatakan bahwa metode yang dilakukan dalam program ini dapat menyelesaikan permasalahan mitra. Kapasitas produksi mitra meningkat sampai dengan 287.5% dari total produksi sebelum program. Kapasitas produksi paling baik sebanyak 300kg/jam pada putaran mesin 1300 RPM dengan mesh 4mm. Pemahaman mitra mengenai pengoperasian dan perawatan alat meningkat hingga 100%. Antusiasme mitra sangat tinggi dalam mengikuti program ini dan berharap kedepannya masih ada program-program pendampingan dan pengabdian serupa.
