Abstract

Komponen valve stem pada engine SAA6D170E-5 mengalami kerusakan berupa goresan setelah dilakukan overhaul engine. Kerusakan yang terjadi berupa goresan pada bagian valve stem. Adapun komponen valve stem yang digunakan merupakan komponen genuine (G) maupun non-genuine (NG). Goresan disebabkan penggunaan alat cotter ring yang sudah tidak sesuai standar penggunaan. Karakterisasi valve stem menggunakan pengamatan visual, pengujian kekerasan metoda Rockwell superficial dan pengamatan struktur mikro. Hasil pengamatan visual menunjukkan bahwa tingkat kedalaman goresan pada valve stem intake G lebih rendah daripada valve stem intake NG. Selain itu, tingkat kedalaman goresan pada valve stem exhaust G juga lebih rendah dibandingkan valve stem exhaust NG. Rendahnya tingkat kedalaman goresan pada valve stem intake G disebabkan angka kekerasan permukaan valve stem intake G lebih tinggi daripada valve stem intake NG. Demikian juga pada valve stem exhaust G yang memiliki angka kekerasan lebih tinggi dibandingkan valve stem exhaust NG. Valve stem intake G memiliki kekerasan lebih tinggi dikarenakan fasa yang terbentuk adalah fasa bainit, sedangkan pada valve stem intake NG adalah fasa perlit. Adapun valve stem exhaust G memiliki kekerasan lebih tinggi dibandingkan valve stem exhaust NG karena fasa perlit yang terbentuk pada valve stem exhaust G lebih rapat.

Abstract

Problems faced by Mangrove Creation Group Lestari is a black mangrove fruit flour caused by the process of less rapid that is drying is too long and during the process of grinding, still simply, that is using a blender. While the blender can only accommodate small capacity and this will inhibit the process of processing raw materials into processed products. The method used in solving the problem of Sustainable Mangrove Creation Group is by socializing the processing process of mangrove flour according to standard, providing flour grinding tool to get good quality flour, and demostration processing of mangrove flour into snack and cake. Based on the results of socialization of community service in Kelurahan Margomulyo can be successful because it sees the enthusiasm of Margomulyo Kelurahan who get the knowledge related to the processing of mangrove fruit flour according to the standard, able to apply or use the disk miller, and the community get standard recipe from swissroll flour mangrove and cimi-cimi mangrove fruit flour.

Abstract

Penurunan ketersediaan air dan peningkatan kebutuhan air telah terjadi di Kabupaten Soppeng, hal ini disebabkan potensi air permukaan sebagai sumber air bersih yang semakin terbatas. Untuk menjamin keberlanjutan program penyediaan air bersih di Kabupaten Soppeng, perlu dilakukan kajian penyediaan air dengan pendekatan sistem, agar penyediaan air di Kabupaten Soppeng dapat berkelanjutan. Penelitian ini dilakukan dengan tujuan untuk menganalisis kendala yang dihadapi, kebutuhan program, dan kelembagaan yang berperan dalam penyediaan air bersih di Kabupaten Soppeng dengan metode Interpretative Structural Modeling (ISM). Hasil penelitian menunjukkan bahwa untuk pelaksanaan program penyediaan air bersih, terdapat empat elemen kunci yang perlu diperhatikan yaitu kurangnya kapasitas kelembagaan, lemahnya tata kelola kelembagaan, ketersediaan air baku, dan peran Pemerintah Pusat (kementerian terkait).

Abstract

The development of sustainable lightweight composites with reliable structural integrity is important for transportation and construction applications. This study investigates a bio-hybrid sandwich composite comprising carbon fibre skins and Oil Palm Frond Fibre (OPFF) as a natural porous core, with emphasis on improving interfacial integrity through chemical modification. The primary objective is to evaluate the effectiveness of sequential NaOH and H₂O₂ treatment in enhancing mechanical performance, interfacial bonding, and thermal stability of the composite system. Hybrid composites were fabricated using an epoxy matrix, combining carbon fibre reinforcements with untreated and chemically treated OPFF cores in various fibre configurations. Mechanical properties were assessed under tensile, flexural, and impact loading, while interfacial morphology and thermal behaviour were examined using microscopy and thermal analysis. The results demonstrate that NaOH + H₂O₂ treatment improves composite performance, with treated unidirectional hybrids exhibiting the highest tensile and flexural strengths. Microscopic observations reveal a substantial reduction in fibre pull-out, debonding, and skin–core delamination, indicating enhanced interfacial integrity and more efficient load transfer. In addition, treated composites show improved thermal stability. The novelty of this work lies in demonstrating that chemically treated OPFF can function as a sustainable sandwich core, where improved interfacial bonding plays a decisive role in suppressing delamination and enhancing overall composite performance.
