Analisa Kegagalan pada Poros Baja Karbon S45c Aplikasi Komponen AS Sink Roll

Telah terjadi kegagalan pada komponen poros baja karbon, kegagalan terjadi pada saat komponendioperasikan. Poros untuk aplikasi as sink roll berfungsi untuk memutar drum, poros atau asdisambungkan dengan drum melalui pengelasan, pada area lasan tersebut terjadinya kegagalan.Untuk mengetahui penyebab terjadinya kegagalan, dilakukan serangkaian pengujian terhadapkomponen as sink roll antara lain : pengamatan visual (fraktografi), pengujian komposisi kimia,pengamatan metalografi, pengujian kekerasan dan pengujian SEM/EDS pada bagian komponenyang mengalami kegagalan. Hasil pengujian menunjukkan material komponen as sink roll sesuaidengan standar JIS G4051 S45C untuk kategori Carbon Steels for Machine Structural Use.Kegagalan yang dialami adalah kegagalan fatique dengan daerah awal retakan berasal dari bagiantepi komponen. Kegagalan ini terjadi disebabkan oleh konsentrasi tegangan pada daerah logam lasselama komponen dioperasikan, adanya mikroporositas di permukaan logam las dan adanyainklusi

Analisa Kegagalan Komponen Front Axle pada Kendaraan Bermotor Roda Empat

Kegagalan material berupa patahnya front axle bagian kanan dan bagian kiri pada komponen kendaraan bermotor roda empat jenis bus terjadi pada saat kendaraaan sedang beroperasi. Analisa kegagalan ini dilakukan untuk mengetahui penyebab utama dan mekanisme kegagalan yang mengakibatkan patahnya front axle pada kedua bagian serta memberikan solusi agar kegagalan serupa dapat dihindari dikemudian hari. Pengujian telah dilakukan berupa fraktografi melalui pengamatan visual secara makro dan mikro, uji kekerasan mikro vickers dan metalografi diharapkan dari serangkaian pengujian dan evaluasi dapat diketahui faktor penyebab kegagalan. Material komponen front axle dapat dikelompokkan kedalam baja karbon paduan rendah, analog dengan standar JIS G5111 SCC5 (high tensile strength carbon steel and low alloys steel castings for structural purpose) dengan nilai kekerasan rata-rata 262,9 – 291,0 HV hasil proses quench & temper serta memiliki struktur mikro martensit temper. Jenis patahan yang terjadi adalah patah ulet terjadi pada bagian atas komponen di tandai dengan bentuk permukaan yang lebih halus akibat kegagalan akibat beban lebih (over load) sehingga melebihi batas luluh material pada saat operasi. Kegagalan akibat beban lebih pada kasus ini terjadi akibat adanya porositas pada material sehingga dapat menurunkan kekuatan material

Empowering Women in Papua Province, Indonesia as Part of the Green Economy

The empowerment of women has been shown to have a positive effect on economic growth. Previous studies have established the importance of women in supporting the family economy. Indigenous Papuan women become empowerment agents who have a tangible impact on improving the family economy and society as a whole. In Papua, Indonesia, the concept of the green economy has been incorporated into the process of women's empowerment. Mama Papua, the term for a native Papuan woman from Jayapura City, is a shining example of women's empowerment achieved through the use of natural products. Mama Papua sell natural products to the city after simple processing. Women as subjects of development, according to this concept, will provide economic benefits while also playing an active role in environmental sustainability. Women and nature play an important role. The concept of a green economy ensures that economic empowerment for women can coexist with environmental protection and preservation. This research examined the interactions that occur during the process of empowering women in Papua who use natural resources. The concept of the green economy maintains traditional ways of processing nature. The research methods used were observation and interviews which were conducted with the provincial Bappeda, representing the Papua City Government, and Mama Papua, representing the Papuan government's empowerment policy. The researchers conducted field research in the Mama Papua market to observe empowerment practices in action. This was followed by a review of the literature on the interactions between empowerment and the green economy from a variety of sources, including policy documents and journals. Triangulation of sources and data was carried out to ensure the data's validity and reliability. The process of empowering women was examined through four factors: access, participation, control and benefits. The findings revealed that government access is still restricted to indigenous Papuan women, also known as Mama Papua. Given that levels of poverty in women are higher than in men, this is a form of affirmative action. Women's aspirations have been accommodated in terms of participation, as evidenced by the presence of the first Mama Papua market in Jayapura, a traditional shopping center that offers a variety of natural products. Women's representation is a factor that influences the long-term viability of women's empowerment in Papua. The control factor demonstrates that women have more control over government policy than men in the Mama Papua market. With the designation of the Mama Papua market as a tourist destination by the Papua City Government, it can be concluded that the empowerment of women through the use of the green economy was successfully implemented, namely the empowerment of women based on promoting small producers and integrating Papuan businesses and local service providers into the value chain. The success of the green economy concept in empowering women must be maintained. The Government's expansion of women's empowerment to the interior of Papua will have a greater impact on the program's long-term viability. The green economy is a unique idea that should be implemented, especially for Papuan native women whose assets are still underutilized. The Government's commitment to improving the welfare of Papuan women by making policies that are sustainable and friendly to Papuan women was another finding in this study.

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
