Abstract

Crash box merupakan sistem keselamatan pasif yang digunakan untuk mengurangi tingkat keparahan kecelakaan yang dialami penumpang atau bagian kendaraan yang vital akibat tabrakan. Penelitian ini meninjau pengaruh variasi sudut tirus dinding dan trigger circles pada crash box berpenampang lingkaran (circular) terhadap penyerapan energi dan pola deformasi pada uji simulasi pembebanan quasi-static. Penelitian dilakukan dengan software berbasis Finite Element Method (FEM). Variasi yang digunakan dalam penelitian ini yaitu crash box dengan sudut tirus 1° dan 5,7° dan letak trigger circles A, B, C dan D dengan material crash box Aluminium 6061-T4. Dari hasil penelitian diperoleh bahwa pola deformasi yang terbentuk adalah pola aksial dengan mode campuran (concertina + diamond). Deformasi mode campuran terjadi pada crash box sudut tirus 1° dan 5,7°. Penyerapan dengan kemampuan menyerap energi terbesar pada crash box dengan sudut tirus (α) 5,7° sebesar 3124,0 J.

Abstract

Penelitian terhadap sebaran situs-situs dengan indikasi tinggalan arkeologis dari bangsa penutur bahasa Austronesia di Mamuju selama ini fokusnya di sepanjang daerah aliran sungai Karama. Sejumlah situs di daerah aliran Sungai Simboro juga mengandung data arkeologi semacam, tetapi belum ada penelitian arkeologi yang dilakukan di sini. Penelitian ini bertujuan untuk memahami persebaran budaya Austronesia di daerah aliran Sungai Simboro, terutama di kawasan Sese. Pengumpulan data primer dilakukan dengan survei arkeologi di lima situs terbuka yaitu, Gattungan, Demmanapa, Koronganak, Talopi, dan Kayu Colo, serta perekaman koordinat situs-situs memakai global positioning system. Selanjutnya, titik-titik koordinat diolah untuk membuat peta sebaran situs menggunakan software pemetaan geographic information system. Pengumpulan data sekunder dilakukan melalui studi pustaka dan arsip, serta wawancara terbuka terhadap tokoh-tokoh masyarakat lokal. Analisis data survei dilakukan secara makroskopis, serta perbandingan analogis dengan data etnografi dan kajian sumber sejarah. Hasil survei di kelima situs terbuka tersebut adalah data arkeologis berupa fragmen gerabah, fragmen keramik, beliung, batu ike (bark-cloth beater), lumpang batu, manik-manik, artefak logam, dan cangkang kerang. Fragmen gerabah ditemukan di kelima situs di Sese. Fragmen keramik ditemukan di empat situs, kecuali situs Koronganak. Alat batu ditemukan di situs-situs Gattungan, Demmanapa, dan Kayu Colo. Perhiasan berupa manik-manik ditemukan di situs-situs Gattungan dan Kayu Colo. Peralatan logam dan cangkang kerang ditemukan di situs-situs Gattungan dan Kayu Colo. Variabilitas data arkeologi dan etnografi menunjukkan karakter budaya neolitik dari masa prasejarah berlanjut hingga ke masa sejarah di kawasan Sese, dan merupakan bukti signifikan kehadiran bangsa penutur bahasa Austronesia di daerah aliran sungai Simboro. Many sites in the Simboro River basin provide potential archaeological remains of the Austronesian-speaking peoples, but no research has been carried out there. This research aims to understand the spread of Austronesian culture in the Simboro River basin, specifically in the Sese region. Primary data collection was carried out by archaeological surveys at five open sites i.e., Gattungan, Demmanapa, Koronganak, Talopi, and Kayu Colo. Secondary data was collected through library and archive studies, and open interviews with local community figures. Archaeological data was analysed macroscopically, supported by analogical comparisons with ethnographic data and historical source studies. The survey yielded potsherds, stone tools including hand adzes, bark-cloth beaters, stone mortars, beads, metal artifacts, and shells. The variability of archaeological and ethnographic data shows that the neolithic cultural characteristics from the prehistoric period continued into the historical period in the Sese area and is significant evidence of the presence of Austronesian-language speakers in the Simboro River basin.

Abstract

This study explores the implementation of a holistic community service program in Siponjot Village, North Sumatra, aimed at enhancing non-formal education, economic sustainability, and environmental resilience. Through the "Marsiajar Manang Didia Pe" initiative, the program promotes a flexible learning system aligned with local cultural values, addressing gaps in formal education. Key components include training in agricultural practices focusing on coffee and mahogany cultivation alongside the introduction of data-driven decision making tools such as economic mathematical models and QR codes for improved information management. Results indicate improved community engagement, increased agricultural productivity, and enhanced digital literacy. The findings highlight the critical interplay between education, technology adoption, and sustainable practices in fostering community empowerment and resilience against environmental challenges.

Abstract

This study examines the performance of a three-phase decanter centrifuge in separating oil, water, and solids in palm oil mills. Efficient separation is critical to improving crude palm oil (CPO) yield and minimizing losses, yet many mills face challenges such as excessive sludge, unstable emulsions, and oil loss. The objective of this research is to compare the operational performance of decanters at A and B mills and to identify the dominant factors influencing oil loss. A case study approach was employed, combining sampling of light, heavy, and solid phases with operational data analysis and direct observations. The results indicate that PKS A experienced high non-oil solids (NOS) in the feed, which caused excessive oil loss in the sludge, while PKS B faced unstable and high emulsion levels, resulting in greater oil loss in the heavy phase. These findings confirm that decanter performance is highly site-specific, even when identical machines are used. The study concludes that operational strategies must be tailored: reducing NOS in PKS A and controlling emulsions in PKS B. The main contribution of this research is providing empirical evidence of differing decanter challenges across mills, offering practical guidance for optimization. The limitation lies in the scope restricted to two mills, suggesting that future research should include more sites and external variables to develop a comprehensive optimization model.
