Abstract

Blade turbin PLTU 400 MW ditemukan dalam keadaan patah. Kondisi ini diketahui pada saat major inspection dilakukan, dimana turbin sudah beroperasi selama 35 tahun. Patah pada blade sudah terjadi cukup lama sehingga terbentuk kerak oksidasi pada area patahan. Blade tersebut terletak pada tingkat Low Pressure (LP) Turbin. Material blade adalah Stainless Steel 17-4 PH. Analisis kegagalan dilakukan untuk mengetahui penyebab patah pada blade sehingga tidak terulang kembali dan mendapatkan rekomendasi untuk operasi turbin selanjutnya. Metodenya dengan melakukan verifikasi material blade, investigasi kegagalan dengan pemeriksaan visual dan fraktografi. Hasil dari investigasi menunjukkan bahwa kegagalan yang terjadi bukan berasal dari material blade. Penyebab patah diinisiasi oleh cacat pada leading edge karena benturan benda asing atau Foreign Object Damage (FOD). Pada saat penelitian ini dilakukan FOD tersebut belum bisa diidentifikasi wujudnya. Pada area blade yang patah terdapat bukti berupa beachmark, sehingga patah yang terjadi adalah patah fatigue. Perawatan berkala dengan interval yang lebih pendek perlu dilakukan untuk mencegah kegagalan terulang

Abstract

Solar energy as a renewable energy source, is currently an important alternative to meet energy needs because of its unlimited amount and environmentally friendly. Almost the entire surface of the earth receives sunlight optimally, so breakthroughs are needed to transform the solar energy into electricity. In the research development process that was to develop advanced materials to support the development of alternative energy. Thin film synthesis was carried out using the Physical Vapor Deposition (PVD) of Direct Current (DC) Sputtering method on Indium Tin Oxide (ITO) substrates using Copper Indium Gallium Selenide (CIGS) and TiO2 with deposition time variations of 30, 45, and 60 minutes. Based on the test results, thin film surface with the largest grain size is 266.75 nm at CIGS/TiO2 45 minutes. This shows that more CIGS and TiO2 atoms are released from the target surface, forming clumps that cover the substrate surface along with the addition of deposition time. The longer the deposition time shows the higher the absorbance value. The highest absorbance value is 4.60873, which was achieved by 60 minutes CIGS/TiO2 sample with wavelength of 271 nm.

Abstract

The Oyster Mushroom Women Farmers Group (KWT) is a group of productive women and has the potential for adequate social capital in driving the community's economy, especially helping to alleviate family finances. The Oyster Mushroom KWT production capacity has a capacity of 50-70 kg per/day, but its growth is hampered by technological stagnation machines, low bargaining power, fuel-intensive sterilization, and physical insecurity for the elderly, especially women. The Community Service Team of the Universitas Kebangsaan Republik Indonesia (UKRI) from the Communication Science, Mechanical Engineering, and Digital Business study programs proposed a solution to the problems faced by the Oyster Mushroom KWT with Appropriate Technology (TTG) in the form of three main machines, namely: Smart Biomass IoT Boiler, Chopper, and Straw Crusher with Soft-start Inverter VFD (Variable Frequency Drive). The implementation of the technology is in the form of the need to accommodate limited village electricity power (900 VA) and is ergonomically designed for female operators, women-friendly technology. At the next level, efforts are made to build entrepreneurship that creates social impact for the community by building social independence and increasing the income of women in Padasuka Village and reducing unemployment. The implementation of manufacturing engineering and modification of women-friendly technology carried out through basic technological literacy and practical training on the use of three machines for the administrators and members of the Oyster Mushroom KWT accompanied by the IMC concept and strategy through Focus Group Discussion (FGD) activities and workshops have provided empowerment and benefits in the down-streaming of women-friendly oyster mushroom technology that fosters sociopreneurs in the Padasuka Oyster Mushroom KWT. The climate and culture of socio-preneurs that have grown need to be maintained and further developed with intensive mentoring and training to reach a wider market through the virtual world, namely digital media and social media in order to provide real impact and evidence on social benefits and sustainable economic profitability as an implementation of socio-preneurial mental toughness.
