Abstract

Biodiesel represents a renewable, environmentally friendly, and locally producible alternative to conventional diesel fuel. This research synthesized biodiesel from kapok seed oil (Ceiba pentandra) via transesterification using a TiO₂ catalyst, with process parameters optimized to maximize yield. Kapok seed oil was extracted using Soxhlet extraction with n-hexane and purified by vacuum column chromatography. The transesterification process involved systematic variation of the oil-to-methanol molar ratio, catalyst mass, reaction temperature, and reaction time. Optimal conditions were established at a 1:10 molar ratio, 0.20 g of catalyst mass, a reaction temperature of 60 °C, and a reaction time of 90 minutes, resulting in a biodiesel yield of 71.58%. Characterization of the biodiesel revealed a density of 0.88 g/mL, viscosity of 3.10 cSt, acid value of 1.89 mg NaOH/g, and saponification value of 231.879 mg KOH/g. GC-MS analysis identified methyl palmitate, methyl linoleate, and methyl oleate as the principal methyl ester components, with methyl oleate as the predominant species. These findings demonstrate that biodiesel derived from kapok seed oil possesses properties suitable for use as an alternative fuel that meets established quality standards.

Abstract

Wire rope is a critical lifting component in Ship-to-Shore (STS) cranes, whose failure can lead to catastrophic system breakdowns, posing significant safety risks and operational losses. This study investigates the root causes of wire rope failure on a 40-ton capacity STS crane. The methodology integrates Root Cause Analysis (RCA) with a Finite Element Analysis (FEA) simulation using ANSYS Static Structural. The analyzed wire rope has a 28 mm diameter, a 6x36 IWRC configuration, and is made of galvanized high-carbon steel. Simulation results under full operational load revealed a maximum von Mises stress of 681 MPa, exceeding the material's yield strength (≈650 MPa), a total displacement of 16 cm, and a critically low safety factor of 0.53. The failure location was identified on the outer strands at the contact points with sheaves, indicating high-stress concentration zones. Furthermore, the calculated Safe Working Load (SWL) for a standard safety factor of 5 was 82.83 kN, which is drastically lower than the 400 kN operational load per rope, confirming severe overstress conditions. The RCA fishbone diagram identified key contributing factors: material specification mismatch, suboptimal sheave design, inadequate maintenance protocols, and insufficient design-stage analysis. The study concludes that the wire rope is unfit for service under current conditions and recommends immediate replacement, revised preventive maintenance schedules incorporating FEA, design optimization of support components, and implementation of real-time load monitoring systems.

Abstract

Pada masyarakat Korong Sigaung di Nagari Sungai Asam, Kecamatan 2x11 Enam Lingkung, Kabupaten Padang Pariaman, peran UMKM berbasis digital dapat dihubungkan dengan upaya meningkatkan pendidikan anak. Penelitian ini bertujuan untuk mengkaji implementasi UMKM berbasis digital sebagai sarana untuk meningkatkan pendidikan anak di masyarakat Korong Sigaung. Metode yang digunakan meliputi studi literatur, survei lapangan, pelatihan, dan evaluasi partisipatif. Melalui partisipasi aktif masyarakat dan kolaborasi dengan pelaku UMKM lokal, dilakukan pelatihan mengenai pemanfaatan teknologi digital, pemasaran online, manajemen bisnis, serta pengelolaan keuangan. Hasil dari pengabdian ini menunjukkan bahwa penerapan strategi UMKM berbasis digital secara efektif mampu memberikan dampak positif pada pendidikan anak di masyarakat Korong Sigaung. Keterampilan yang diperoleh oleh pelaku UMKM lokal dalam mengelola usahanya secara digital turut meningkatkan pemasukan ekonomi keluarga, yang pada gilirannya mendukung akses pendidikan yang lebih baik bagi anak-anak. Selain itu, terciptanya jejaring kolaboratif antara UMKM dan lembaga pendidikan setempat memfasilitasi peningkatan akses informasi dan pembelajaran bagi anak-anak. Penelitian ini memberikan kontribusi berharga dalam merancang model berkelanjutan untuk pemberdayaan UMKM berbasis digital dalam mendukung pendidikan anak di wilayah pedesaan. Peningkatan kualitas pendidikan anak melalui pendekatan ini memiliki potensi untuk meningkatkan taraf hidup masyarakat Korong Sigaung secara keseluruhan. Namun, tantangan yang berkaitan dengan infrastruktur teknologi, literasi digital, dan pemahaman konsep bisnis tetap perlu diatasi dalam rangka menjaga keberlanjutan program ini. Kata Kunci : Peningkatan UMKM, Berbasis Digital, Pendidikan Anak
