Abstract

Penelitian ini menganalisis studi kasus sistem perawatan genset perkins 45 kVa di PT. Agrolestari mandiri NTYE, Nanga Tayap, yang berfungsi sebagai sumber listrik utama untuk operasional perusahaan. Mengingat pentingnya peran genset, penelitian ini bertujuan untuk mengidentifikasi permasalahan umum dan mengevaluasi efektivitas program perawatan yang diterapkan.Metode penelitian kualitatif deskriptif digunakan dengan pendekatan observasi, wawancara, dan analisis data operasional. Hasil penelitian menunjukkan bahwa perawatan genset masih menghadapi beberapa kendala, termasuk masalah low power, overheat, kebocoran seal, dan keterlambatan penambahan coolant. Untuk mengatasi hal tersebut, perusahaan menerapkan perawatan preventif harian, mingguan, bulanan, dan tahunan yang berfokus pada pengecekan dan penggantian komponen esensial, serta penanganan kerusakan secara berjenjang.Hasil penelitian menunjukkan bahwa Genset Perkins 45 kVA di PT. Agrolestari Mandiri NTYE mengalami beberapa permasalahan utama, seperti low power, overheat, kebocoran seal, kerusakan pipa injeksi, dan ketidakstabilan RPM. Faktor penyebabnya meliputi radiator yang kotor, gangguan pada relay, serta keterlambatan penambahan coolant yang menurunkan efisiensi sistem pendinginan. Frekuensi service rutin yang rendah (dua kali dalam 1,5 tahun) menunjukkan pola pemeliharaan preventif yang belum optimal, sehingga meningkatkan frekuensi perbaikan korektif dan penggantian komponen penting seperti water house, air cleaner, radiator, fuel filter, dan v-belt. Kondisi tersebut mengindikasikan adanya keausan dini akibat kurangnya pencegahan dan pemantauan kondisi komponen. Oleh karena itu, penerapan sistem preventive maintenance yang lebih disiplin dan terjadwal diperlukan untuk menjaga performa serta memperpanjang umur pakai genset

Abstract

Motor bakar masih menjadi sumber tenaga utama pada sektor transportasi dan industri kecil-menengah. Motor bensin (spark-ignition) dan motor diesel (compression-ignition) memiliki karakteristik efisiensi termal yang berbeda akibat perbedaan mekanisme pembakaran, rasio kompresi, dan sifat bahan bakar. Penelitian ini bertujuan membandingkan efisiensi termal motor bensin dan diesel melalui variasi laju aliran bahan bakar dan beban kerja guna menentukan kondisi operasi optimal serta kinerja efisiensi. Metode yang digunakan adalah eksperimen kuantitatif pada engine test bench. Mesin bensin silinder tunggal dan mesin diesel silinder tunggal diuji dengan empat variasi laju aliran bahan bakar (0,8–2,2 kg/jam) dan beban kerja (25%, 50%, 75%, dan 100% torsi maksimum). Parameter yang diamati meliputi efisiensi termal brake, konsumsi bahan bakar spesifik, dan suhu gas buang. Hasil penelitian menunjukkan efisiensi termal motor diesel berkisar antara 28,4% hingga 37,2% (rata-rata 33,1%), sedangkan motor bensin berkisar antara 22,1% hingga 29,5% (rata-rata 25,8%). Efisiensi tertinggi dicapai motor diesel pada laju aliran bahan bakar 1,5 kg/jam dan beban 75%. Variasi laju aliran bahan bakar dan beban kerja terbukti memengaruhi efisiensi termal secara signifikan, dengan motor diesel menunjukkan kinerja unggul pada kondisi beban sedang hingga tinggi. Penelitian ini dapat menjadi acuan dalam optimalisasi konsumsi bahan bakar dan pengembangan mesin pembakaran dalam yang lebih efisien.

Abstract

The use of composites as materials has developed rapidly due to the many advantages they offer compared to alternative engineering materials. In this study, the researchers used Glass Laminated Aluminium Reinforced Epoxy (GLARE) to analyze the results of bending tests on hybrid laminate composites reinforced with fiberglass and aluminum plates. The method used was vacuum bagging, and the sample was reinforced with epoxy resin combined with carbon nanotube (CNT) nanoparticles and aluminum (AL) powder. This study applied variations in resin as adhesive, surface treatments, and the addition of CNT and AL nanopowders to determine their effects on the bending strength of the composite. The results showed that specimens with surface treatment and nanoparticle additions had higher bending strength compared to those without nanoparticles or surface treatment. The highest bending stress was found in the CNT variation specimens, with an average value of 181.4158 MPa. The lowest average bending stress was observed in the plain specimens without nanoparticles and surface treatment, with a value of 151.766 MPa. Macro photo analysis after the bending test showed adhesive failure in the plain variation (no resin adhered to the aluminum surface), and cohesive failure in the CNT variation (resin adhered to the treated aluminum surface). These findings indicate that the addition of nanoparticles improves bending strength. This research plays an important role in understanding the influence of nano adhesives and nanoparticles on the bending strength of hybrid laminate composites.

Abstract

An evaluation of unconfined groundwater at the Air Dingin Landfill (TPA) in Padang City, West Sumatra, has been conducted to assess the impact of leachate on the water quality utilized by the surrounding community. Groundwater samples were collected from ten strategically selected points around the landfill, with support from JPS. The leachate characteristics analyzed included pH, temperature, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), total dissolved solids (TDS), total suspended solids (TSS), and the concentrations of heavy metals such as Pb, Cu, Mn, As, Cd, Cr, and Fe. A thermometer and a pH meter were employed to measure temperature and pH levels, respectively. The concentrations of heavy metals were determined using Atomic Absorption Spectroscopy (AAS), while BOD, COD, TDS, and TSS values were assessed through the gravimetry method.The test results for various parameters, including odor, taste, temperature, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and levels of heavy metals (Pb, Cu, Mn, As, Cd, Cr, and Fe), generally remain below the quality standards outlined in Indonesian Minister of Health Regulation No. 416 of 1990 and Government Regulation No. 82 of 2001. However, the pH levels of the unconfined groundwater measured between 3.04 and 6.05, which do not meet the Government's requirements for all test wells. Additionally, the leachate does not appear to impact the quality of the unconfined groundwater surrounding the Air Dingin Landfill. Overall, the groundwater quality in this area generally complies with the standards set forth in Minister of Health Regulation No. 416 of 1990 and Government Regulation No. 82 of 2001..

Abstract

Zircon sand (Zr) is widely associated with alluvial deposits, particularly in Ketapang Regency. Despite the considerable zircon resource potential, information regarding its occurrence and spatial distribution at a local scale remains limited. Identifying zircon sand occurrence is therefore essential as an initial step in evaluating and developing Zr resource potential. This study aims to determine the occurrence and analyze the spatial distribution of zircon sand in Kendawangan District, Ketapang Regency. Geologically, the study area is predominantly composed of swampy mud deposits (Qs). The geomorphology consists of two main landform units: Alluvial Plain Unit (Al) covering approximately 65% and Swamp Plain Unit (Dr) covering 35%. A total of 24 boreholes were drilled on a 150 m × 150 m grid over an area of 200 hectares. The subsurface is classified into three layers (A, B, and C), with 1 kg samples collected from each layer. Spatial distribution mapping of Zr was conducted using QGIS with the Inverse Distance Weighting interpolation method. The Zr grade distribution in Layer A is dominated by low to moderate values (6–28 mg), relatively uniform across the study area, indicating low to moderate mineralization potential. In Layer B, Zr grades are predominantly high (39–62 mg) and widely distributed, particularly in the central to southern parts, suggesting higher mineralization potential and better prospectivity for exploration. Layer C exhibits more heterogeneous distribution, with moderate to high grades (28–50 mg) covering most of the area, indicating a fairly favorable mineralization potential.
