Abstract

Sektor UMKM jasa instalasi meja biliar menghadapi kendala serius terkait penanganan material secara manual, khususnya saat mengangkat slate (batu alam) seberat 150 kg. Aktivitas ini berisiko tinggi memicu Musculoskeletal Disorders pada pekerja dan sangat tidak efisien secara operasional. Oleh karena itu, kegiatan pengabdian ini bertujuan untuk mengimplementasikan teknologi tepat guna berupa Perangkat Angkat Gunting (Scissor Lift) Manual bagi mitra PT Kreasi Tiga Bola. Pelaksanaan pengabdian menggunakan pendekatan User-Centered Design, yang meliputi tahapan survei lapangan, perancangan desain, fabrikasi, uji coba fungsional, serta pelatihan Keselamatan dan Kesehatan Kerja (K3). Hasil pengabdian menunjukkan adanya perbaikan postur pekerja ke posisi berdiri netral yang berhasil menurunkan Lifting Index (LI) dari kategori sangat berbahaya menjadi aman (LI < 1). Selain itu, intervensi alat ini terbukti memangkas waktu pemosisian material dari 20 menit menjadi kurang dari 5 menit, serta mengoptimalkan kebutuhan tenaga kerja dari 4 menjadi 2 orang. Pelatihan yang diberikan juga berhasil meningkatkan pemahaman K3 teknisi sebesar 85%. Kesimpulannya, penerapan scissor lift manual ini sangat krusial karena efektif mengeliminasi risiko cedera fisik sekaligus memberikan nilai tambah berupa peningkatan efisiensi ekonomi dan produktivitas usaha mitra.

Abstract

Background: The increasing degradation of urban surface water quality due to suspended solids, dissolved metals, and anthropogenic activities has driven the demand for simple, cost-effective, and sustainable water treatment technologies. Methods: This study evaluated a Basic Water Purification System (BWPS) during its start-up phase, examining water quality changes associated with the stabilization of newly installed filtration media. Surface water from a retention pond was treated using a multi-media filtration system consisting of zeolite, silica sand, activated carbon, anthracite, manganese sand, and ion exchange resin across three configurations. Temperature, total dissolved solids (TDS), turbidity, color, pH, nitrate, nitrite, Fe, and Mn concentrations were assessed at three sampling points. Results: TDS, turbidity, color, Fe, and Mn concentrations increased after filtration, resulting in negative removal efficiencies attributable to initial leaching from the newly installed media. However, TDS, Fe, and Mn concentrations consistently declined from the first to the third sampling point, indicating progressive media stabilization. Media 2 demonstrated the most consistent performance, maintaining a near-neutral pH range (6.3–7.2) and the lowest TDS levels, while Media 3 achieved the highest Fe removal efficiency (13.53%). Correlation analysis revealed strong positive relationships between TDS and dissolved metal concentrations, as well as between turbidity and color, confirming that these fluctuations were associated with media conditioning rather than inadequate treatment performance. Conclusion: These findings confirm that the Basic Water Purification System (BWPS) is a promising low-cost, decentralized option for urban surface water treatment, provided that an adequate media conditioning period is implemented before full-scale operation.

Abstract

Indonesia, as one of the largest palm oil producers, generates large amounts of biomass waste including oil palm fronds. This waste has the potential to be utilized as an alternative raw material for environmentally friendly packaging products such as pulp-based egg trays. This study aims to analyze the cost of goods manufactured (COGM) of egg trays made from oil palm frond waste using the full costing method. The calculation includes direct raw material costs, direct labor costs, variable manufacturing overhead costs, and fixed manufacturing overhead costs. The results show that the COGM of egg trays made from oil palm fronds is Rp1,050 per unit. The largest cost component comes from direct labor, indicating that the production process is still semi-manual and labor-intensive. Compared with the indicative market price of conventional cardboard egg trays, which ranges from Rp800 to Rp1,000 per unit, the product cost is slightly higher. However, market prices may vary depending on purchase scale, product quality, and specifications. This study indicates that egg trays made from oil palm frond waste have promising potential, particularly through improvements in productivity, process efficiency, and larger-scale production.
