Abstract

Hardenability is the ability of a material to harden to a certain depth utilizing heat treatment to form martensiteupon cooling to achieve a certain hardness. The hardness of a metal, especially steel, can be modified withoutadding alloying elements and is done by heat treatment. Steel's hardenability value is strongly influenced by thecarbon content (carburizing) in the steel structure. Increasing the hardness of a material can be done by addingcarbon to the object's surface during heat treatment. The Rockwell Hardness Test method measures the surfaceof the hardness. The test results on the specimens showed that the carburizing process of each specimenincreased the hardness of the surface of the specimen. The distribution of hardenability values is close to alinear line, namely the heat treatment temperature 900℃

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

The availability of clean water services in Sukabaru Village, Ketapang Regency, has experienced disruption due to leakage in the storage tank, low pump pressure, and blockages and leaks in the pipeline network, causing water distribution to residents to stop for several months. This Community Service Program under the Village Empowerment Scheme of Politeknik Negeri Ketapang aimed to restore the clean water supply and distribution system while supporting the sustainability of service management by the Village-Owned Enterprise (BUMDes). The program was implemented using a participatory approach involving the community service team, village government, BUMDes, and residents. The activities included field identification, technical planning, storage tank repair, installation of two 1.5 HP water pumps, pipeline network normalization, and system testing. The results showed that tank leakage was reduced, the pumping system was restored, and blocked and leaking pipelines were normalized. Following the revitalization, water flow reached households that had previously been without supply. The program directly benefited approximately 80 households. The revitalization successfully restored clean water services and supported BUMDes performance. Routine maintenance and sustainable management are recommended to maintain the functionality of the system.

Abstract

Internet access availability is an important requirement for supporting access to information and the use of technology in rural communities. This community service activity aimed to develop an internet network in public spaces in Sukabaru Village, Benua Kayong District, Ketapang Regency. The implementation method was carried out in stages through needs identification, site surveys, coordination with relevant stakeholders, and network implementation. Initial needs identification was conducted through problem identification activities, followed by a site survey to determine the locations and requirements for network development. The network was implemented at three public spaces, namely the Village Office, Village Park, and Model House, using network devices and transmission media adapted to field conditions. The results of the activity showed the availability of internet network infrastructure connecting the three public spaces, which can be utilized to support access to information and the activities of the village government and community. This activity demonstrates that field-based, needs-oriented network development can serve as an effort to expand the utilization of information technology in rural communities.
