Abstract

Perkembangan Industri manufaktur yang berkembang sangat pesat sehingga hasil Produk dari industri manufaktur harus memiliki kualitas yang tinggi, terutama produk hasil permesinan seperti produk pembubutan. Baja AISI 1045 adalah salah satu jenis baja karbon rendah dengan kandungan karbon sebesar 0,43 hingga 0,50%. Itu sering digunakan di pasar karena banyak keunggulannya dan harganya yang murah. Getaran yang terjadi selama proses pembubutan dapat menyebabkan efek yang tidak dikehendaki, seperti kebisingan, pengukuran yang salah, dan hasil pembubutan yang tidak optimal. Penilitian ini menyelediki pengaruh dari parameter pembubutan yaitu feed dan putaran spindel terhadap kekasaran pemukaan dan amplitudo getaran pembubutan baja AISI 1045 dengan menggunkan pahat karbida. Pengukuran kekasaran permukaan dilakukan menggunakan Microscope OLS4100 dan amplitudo getaran diukur menggunakan vibxpert II. Analisis yang dilakukan dari hasil pengukuran menggunakan perangkat lunak Minitab Statistical Software 22. Dari hasil analisis yang dilakukan, faktor feed merupakan faktor yang paling signifikan terhadap hasil kekasaran permukaan maupun amplitudo getaran. Parameter permesinan yang paling optimal terhadap kekasaran permukaan yaitu adalah feed 0.1 mm/put (lvl 1), kecepatan spindle 400 rpm (lvl4) dengan nilai kekasaran permukaan 4.757 µm. Parameter permesinan yang paling optimal terhadap Amplitudo getaran yaitu feed 0.1 mm/put (lvl 1) dan kecepatan spindle 100 rpm (lvl 1) dengan nilai amplitudo getaran adalah 0.11 m/s.

Abstract

Industri nikel Indonesia yang berkembang pesat menghasilkan limbah slag nikel dalam jumlah besar yang mencapai 13 juta ton per tahun. Slag nikel sebagai produk samping dari proses pyrometallurgy peleburan feronikel memiliki potensi besar untuk dimanfaatkan sebagai material alternatif ramah lingkungan dalam konstruksi berkelanjutan. Penelitian ini bertujuan untuk mengkaji potensi pemanfaatan slag nikel dalam industri konstruksi melalui studi literatur komprehensif. Metode yang digunakan adalah systematic literature review dengan menganalisis publikasi ilmiah dari tahun 2014-2025 yang membahas aplikasi slag nikel dalam material konstruksi. Hasil penelitian menunjukkan bahwa slag nikel dapat digunakan sebagai pengganti parsial semen Portland dengan kandungan optimum 10-20%, agregat halus pengganti pasir dengan rasio substitusi hingga 50%, dan bahan baku dalam produksi geopolimer. Pemanfaatan slag nikel terbukti meningkatkan kuat tekan beton hingga 15-25%, mengurangi permeabilitas, dan memberikan ketahanan yang baik terhadap lingkungan agresif. Dari aspek lingkungan, penggunaan slag nikel dapat mengurangi emisi CO2 hingga 30% dibandingkan beton konvensional dan mengurangi eksploitasi sumber daya alam. Kesimpulan penelitian ini menunjukkan bahwa slag nikel memiliki potensi yang sangat baik sebagai material alternatif ramah lingkungan dalam konstruksi berkelanjutan, namun masih memerlukan standardisasi dan regulasi yang mendukung implementasinya secara massal.

Abstract

This initiative addressed the critical deficit in public street lighting in Soropia Village, which hindered safety, mobility, and economic activity after dusk. Moving beyond mere infrastructure provision, the project's core objective was to establish a sustainable, community-owned model for public lighting through comprehensive technical capacity building and institutional development. Employing a participatory rural appraisal (PRA) framework, the project engaged 35 local participants in a multi-phase process over June 2025. This included collaborative identification of problem areas, co-design of technical solutions using locally-sourced and recycled materials, and an intensive, hands-on workshop. The technical design specifically utilized recycled metal pipes fabricated by participants, reinforced concrete foundations (40cm x 40cm x 60cm), and a safe electrical system with LED technology, proper grounding, and overcurrent protection connected to the existing grid. The project yielded three primary outcomes: 1) The successful installation of multiple functional, community-fabricated street lights at strategic locations; 2) A measurable enhancement of technical skills among participants, enabling independent maintenance and replication; and 3) The emergence of a formalized community task force committed to the project's longevity. Pre- and post-workshop assessments showed a 75% increase in technical self-efficacy scores among participants. The Soropia model demonstrates that integrating technical education with community-led implementation and early institutionalization fosters profound and sustainable empowerment. The transformation of participants from passive beneficiaries to active managers of their infrastructure is the key success metric. For scalability, we recommend integrating a micro-enterprise component to ensure financial sustainability for ongoing maintenance and expansion, thereby creating a replicable blueprint for rural infrastructural development.

Abstract

Low-rise buildings, broadly defined as structures of one to four storeys, represent the dominant residential and small commercial building typology in many countries, particularly across Southeast Asia, Sub-Saharan Africa, Latin America, and parts of the Middle East. Their demolition—whether for urban regeneration, post-disaster clearance, or individual redevelopment—spans a wide spectrum of approaches, from entirely manual hand-tool operations to fully mechanised excavator-based processes. This systematic review comprehensively examines the principal manual and equipment-based demolition techniques applicable to low-rise buildings, analysing each in terms of technical characteristics, operational requirements, safety implications, material recovery potential, and economic performance. The factors governing method selection—including structural typology, site access constraints, proximity to adjacent structures, project budget, and the presence of hazardous materials—are also critically examined. Two structured summary tables are presented: a comparative performance overview and a multi-criteria decision matrix to guide method selection in practice. The review concludes that no single demolition technique is universally optimal; the most appropriate approach is determined by a combination of site-specific, technical, economic, and regulatory factors. Key knowledge gaps are identified, with particular emphasis on developing-country contexts where low-rise demolition is most prevalent yet least formally regulated. Low-rise buildings, broadly defined as structures of one to four storeys, represent the dominant residential and small commercial building typology in many countries, particularly across Southeast Asia, Sub-Saharan Africa, Latin America, and parts of the Middle East.

Abstract

Inisiatif penerapan teknologi energi surya di Fakultas Ilmu Sosial dan Ilmu Politik Universitas Halu Oleo (FISIP UHO) merupakan langkah strategis mendukung keberlanjutan lingkungan melalui energi hijau dan pengurangan ketergantungan terhadap energi fosil. Kegiatan diawali dengan pemasangan lampu jalan tenaga surya di area kampus, yang menggunakan lampu ber-efikasi tinggi untuk pencahayaan optimal tanpa konsumsi listrik konvensional. Tahap selanjutnya adalah sosialisasi energi hijau kepada civitas akademika guna meningkatkan kesadaran akan pentingnya energi terbarukan. Diskusi dalam sosialisasi menghasilkan pembentukan tim peneliti untuk menilai implementasi kebijakan energi hijau di Sulawesi Tenggara. Kegiatan ini ditindaklanjuti dengan penandatanganan Memorandum of Understanding (MoU) antara FISIP UHO dan Politeknik Tridaya Virtu Morosi (PTVM) tentang dukungan penelitian di bidang energi hijau. Hasil kegiatan menunjukkan bahwa program ini berkontribusi terhadap penghematan energi dan peningkatan pemahaman masyarakat kampus, serta berpotensi menjadi model percontohan transformasi kebijakan energi hijau di tingkat lokal.
