Abstract

The industrial world has been developing at an increasingly rapid pace. The use of additive manufacturing technology is increasingly being used by various companies around the world. Fused deposition modeling (FDM) is a type of 3D printing that falls under the category of material extrusion. It is also known as fused filament fabrication (FFF). Fused deposition modeling (FDM) is the most cost-effective additive manufacturing technique. Polylactic acid (PLA) is a type of plastic that is made from renewable resources such as corn starch, tapioca roots, chips or starch, or sugarcane. It is biodegradable and bioactive and can be used for a variety of applications such as packaging materials, disposable tableware, medical implants, and 3D printing. PLA is also used in the food industry as a food packaging material. The goal of this study is to analyse the warping angle of PLA. In this study, the commercial eSUN PLA filament manufactured by Shenzhen Essun Industrial with a diameter of 1.75 mm was used. This study used experimental method with predetermined conditions such as ISO 527-2 printed specimens, annealing temperature at 50⁰C and 70⁰C. The test result shows that annealing at 50⁰C have the highest degree of side view 1.88⁰, and 1.32⁰ on average. The top view have 2.21 ⁰ and 1.19 on average. Afterwards, the study shows that annealing at 70⁰C have the highest degree of side view 6.19⁰, and 3.96 on average. The top view have 3.84⁰, and 2.33⁰ on average.

Abstract

Kebutuhan energi listrik dalam kehidupan manusia tiap tahun semakin meningkat seiring kemajuan teknologi baik untuk kepentingan rumah tangga atau industri. Karena itu dibutuhkan upaya pengembangan dan pemanfaatan energi alternatif yang ada. Penelitian ini bertujuan untuk mengetahui prosentase peningkatan kinerja turbin air dengan sudu berbentuk setengah lingkaran dengan menggunakan variasi jumlah sudu 8, 10, dan 12. Dimensi sudu diameter 10 cm dengan panjang 5 cm dan diameter puli 7 cm. Penelitian dilakukan dalam bentuk miniatur dengan sumber utama air diperoleh dengan bantuan pompa sentrifugal untuk mengisap air dari tandon dengan kecepatan mesin pompa dalam posisi stasioner atau stabil. Dalam penelitian digunakan beban f (kg) 0 kg, 2 kg, dan 4 kg dengan hasil debit air yang dikeluarkan 4,6 l/s. Hasil penelitian menunjukkan bahwa variasi jumlah sudu 10 paling efektif dengan nilai torsi = 0,14 kg.m, daya aktual (BHP) = 1,479 watt, daya teoritis (WHP) = 18,400 watt, serta efisiensi = 8,03 %. Sudu 10 merupakan sudu yang paling baik digunakan pada uji coba mikrohidro aliran arus bawah karena menghasilkan efisiensi yang paling besar dibanding jumlah sudu 8 dan sudu 12.

Abstract

Proses Pengelasan menggunakan sistem las (Shield metal arc welding) SMAW tidak lepas dari meningkatkan dari mutu industri untuk berkembang. Dan pengunaan las ini sangat umum digunakan di indudtrial. Tujuan dari penelitian ini adalah untuk mengetahui variasi media pendingin menggunakan pendinginan udara dan pendingin air garam dengan menggunakan las SMAW dengan variasi sambungan lap joint, dengan pengujian impact dan struktur mikro. Nilai impact rata-rata 90.74 Joule dengan variasi media pendingin air garam, sedangkan nilai rata rata menggunakan variasi media pendingin menggunakan udara yaitu 118.54 Joule. Jadi nilai tertinggi rata-rata adalah menggunakan variasai pendinginan udara dengan nilai 118.54 Joule. Hasil uji metalografi menggunakan pengujian struktur mikro pembesaran 400x dan hasil foto struktur mikro dibuat hitam putih kedalam lembaran kertas mili meter untuk melihat ferit dan perlit. nilai rata-rata ferit tertinggi pada variasi media pendingin udara yaitu sebesar 90.44%. Sedangkan nilai rata-rata ferit terendah menggunakan variasi media pendingin Air garam yaitu sebesar 75.79%.

Abstract

Jurusan D3 Otomotif Fakultas Teknik Universitas Widyagama Malang diarahkan untuk memahami pengetahuan baik secara teori maupun secara praktek yang praktis. Jika sarana dan prasarana proses belajar mengajar terpenuhi, maka dapat memenuhi kebutuhan tenaga kerja didunia industri. Fasilitas alat praktek Sistem Pengapian mobil pada laboratorium sudah ada namun belum seimbang antara jumlah mahasiswa dengan alat praktek sistem kerja valve pada mobil. Guna menghindari kesulitan mahasiswa Jurusan D3 Otomotif dalam melakukan praktek dimasa yang akan datang, maka peneliti membuat modul pembelajaran system kerja valve pada mobil. Sistem valve merupakan proses siklus yang terjadi didalam ruang bakar untuk proses langakh hisap, kompresi, usaha, buang sehingga terjadi kerja valve sesuai kebutuhan mesin, dimana nantinya peroses ledakan tersebut akan menghasilkan tenaga dan gerak. Tujuan sistem ini adalah untuk mengetahui rangkaian sistem kerja valve terutama pada kendaraan mobil 4 silinder. Pengujian atau pengambilan data pada sistem kerja valve menggunakan dial indikator sedangkan untuk mengukur tegan pada indikator lampu LED mengunakan volt meter.

Abstract

One-third of Indonesia's territory is ocean, but Indonesia still experiences difficulties in clean water, especially in coastal areas. Solar still technology can be used to overcome these problems. There have been many studies conducted to improve the performance of solar stills, one of which is to change the shape of the cover or cover. The purpose of this study was to compare the effect of pyramid cover with the addition of condensation chamber (WES). This research uses experimental and theoretical methods. This study used fin absorbent plates using mortar material. The result of this study is the highest solar still performance using the WES cover compared to using the pyramid cover experimentally and theoretically. The highest productivity using WES cover is 2,087 kg / day for experiments and for theoretical values of 2,287 kg / day, while the efficiency obtained is 31.66% for experiments and 32,19% for theoretical. The difference in freshwater productivity and solar still efficiency between experimental and theoretical was not significant.

Abstract

Indonesia has a high potential for solar energy, yet it is not optimally utilized. Additionally, the demand for hot water in Malang City is considerable. To meet this need, solar water heaters (SWH) can harness solar energy. However, one issue with SWH is that the mortar absorber plate has low thermal conductivity. This can be improved by adding copper powder to the mortar absorber plate. This study aims to identify the effects of adding copper powder to the absorber plate to enhance the performance of the solar water heater. The research compares mortar absorber plates with and without copper powder. Testing is conducted with varying flow rates. The study employs experimental methods, utilizing microscopic imaging, thermal conductivity tests, and SWH performance assessments. Microscopic analysis revealed that copper powder mixed with cement enhances the mortar. The addition of copper powder to the absorber plate (SWH.T) increases thermal conductivity by 25.16% compared to the standard version (SWH.S). Efficiency improvements for SWH.T over SWH.S at flow rates of 50, 150, and 250 ml/min are 24.20%, 9.91%, and 11.79%, respectively, with the highest efficiency for SWH.T at 250 ml/min reaching 45.56%.
