Abstract

S-35 C, is a low steel carbon type with 0,30% - 0,35% carbon composition, which has a low hardness. This matter can be overcome by changing the hardness of this steel through heat treatment process. Heat treatment method used in this experiment is pack carburizing method. Experiment results showed that with composition of 500 g of carbon and 0% beef bones with 15 minutes holding time, the hardness number increased as much as 116.90 HRC, there was 20.54 HRC number increased. With 10% of cow bones composition, hardness number became 118.39 HRC and 20.40 HRC number increased. HRC number became 122.20 and increased by 24.38 on 20% composition, and on 30% the hardness value became 130.36 HRC, increased until 32.05 HRC number. 40% composition showed increasing hardness number up to 133.34 HRC, with 35.08 HRC increased. And 50% composition showed 141.29 HRC number, increased until 43.95 HRC. 50% composition produce the highest increase of hardness number, this verified that the higher composition of cow bones makes higher increasing of hardness number in a heat treatment process deliver a harder steel, and also prove that beef bones can be used as a catalyst in pack carburizing process.

Abstract

Sayur yang biasanya dijual pada pasar-pasar swalayan dipajang  di  dalam lemari-lemari  pendingin atau diletakkan pada rak yang berada pada ruangan yang dingin dan memiliki sistem pendingin,  sedangkan di pasar-pasar tradisional sayur ini  hanya dihamparkan di atas meja-meja penjualan, sebagian lagi ditumpuk pada wadah-wadah yang bukan merupakan tempat penyimpanan sayur dan  tidak dilengkapi dengan alat pendingin. Penelitian sebelumnya menunjukkan bahwa kehilangan berat sayur dengan menggunakan sistem water misting dapat dipertahankan sebanyak 6.25% dari berat semula, dengan efisiensi alat pendingin water misting sebesar 61.47%. Penelitian ini diharapkan bisa mendapatkan metode baru terutama sistem kontrol yang dapat diaplikasikan  sesuai dengan kebutuhan manusia khususnya untuk pedagang sayur sehingga mempermudah pekerjaan dengan tidak lagi menyiram atau memercikkan air di atas sayur secara manual tetapi secara otomatis. Hasil penelitian menunjukkan bahwa efisiensi terbaik diperoleh pada waktu penyemprotan 7 menit dengan istirahat selama 2 menit sebesar 65.6%, lebih baik 4% dari penelitian sebelumnya.

Abstract

Electricity requirements increase every year and have become a necessity for every household in the world. Alternative electricity sources will be required to handle the need. New and renewable energy (NRE) offer divers source on this issue; however, the development of these sources demands more exploration. DSSC or Dye Sensitized Solar Cell as the third generation of Solar Cell is one of the sources that can be explored. Using Microalgae as its dye is known to be an excellent choice for alternative natural dye. Navicula TAD, the original type of Microalgae found in Ambon Bay has been proven to be able to be a catalyst in electricity flow on DSSC. This research is investigating the effect of TiO2 paste weight on the efficiency of DSSC that uses Navicula TAD as the natural dye. Early studies showed that as the weight of TiO2 paste increases, the efficiency also increases. Using TiO2 weight of 0.1; 0.3 grams, the greatest efficiency is found in the DSSC with 0.3 grams of paste. The efficiency of DSSC with 0.3 grams of TiO2 paste is 17.02%.

Abstract

Ambon Peaker 30 MW. These pipes are prone to corrosion, especially if not protected by a coating, which leads to thickness reduction and shortens the operational lifespan of the pipes. The thickness measurement will be carried out using an Ultrasonic thickness gauge to determine the corrosion rate and the remaining life of the pipe. The standards referenced in data collection are the American Petroleum Institute (API) 570 and the American Society of Mechanical Engineers (ASME) B31.4. The research will be conducted by the author from August 28, 2024, to August 30, 2024, at PLTMG Ambon Peaker 30 MW, Salahutu District, Central Maluku Regency, Maluku Province. The research results show that the minimum thickness reduction indicates a corrosion rate of 0.228 mm/year at Thickness Measurement Location (TML) 17 and 18, while the maximum thickness reduction shows a corrosion rate of 0.564 mm/year at Thickness Measurement Location (TML) 3. Pipes with lower corrosion rates have a remaining life of 5.4 years, while pipes with higher corrosion rates have a remaining life of up to 31.9 years. In conclusion, coating protection is essential to reduce the corrosion rate and extend the service life of the pipes. Keywords: Pipe thickness, Corrosion rate, Pipe remaining life, Ultrasonic thickness gauge.
