Abstract

Kegiatan edukasi desain kemasan ini bertujuan untuk memperkuat branding produk UMKM lokal di Desa Ujong Blang, Kecamatan Banda Sakti, Kota Lhokseumawe. Dalam menghadapi persaingan pasar yang semakin ketat, kemasan yang menarik menjadi faktor penting untuk meningkatkan daya tarik produk dan nilai jual. Melalui pelatihan dan pendampingan, pelaku UMKM diberikan pengetahuan dan keterampilan dalam merancang kemasan yang efektif dan sesuai dengan karakter produk mereka. Kegiatan ini diharapkan dapat meningkatkan brand awareness serta loyalitas konsumen, sekaligus memperkuat kapasitas UMKM dalam mengelola branding secara mandiri. Pengembangan program edukasi desain kemasan yang berkelanjutan direkomendasikan sebagai salah satu strategi pemberdayaan UMKM lokal untuk mendukung pertumbuhan ekonomi desa.

Abstract

Sistem manajemen keselamatan dan kesehatan kerja (SMK3) merupakan sistem yang menghubungkan memproteksi pekerja, perusahaan, lingkungan hidup, dan masyarakat sekitar dari bahaya akibat kecelakaan kerja. PT. Kunango Jantan merupakan perusahaan kontruksi sebagai penyediaan, pemrosesan, dan distribusi material baja dan beton siap pakai untuk industri konstruksi, kelistrikan, pertambangan, telekomunikasi, dan perhubungan. PT. Kunango Jantan telah membentuk Panitia Pembina Keselamatan dan Kesehatan Kerja (P2K3). Oleh sebab itu, penelitian ini bertujuan untuk mengevaluasi penerapan SMK3 di PT. Kunango Jantan dan mengetahui faktor-faktor yang mempengaruhi penerapan SMK3 tersebut. Metode penelitian dilakukan melalui wawancara dan penyebaran kuesioner kepada pihak manajemen dan pekerja di PT. Kunango Jantan.

Abstract

Coconut agro-industries in tropical regions, including Indonesia, play a critical role in rural economies but often face challenges related to low resource efficiency, fragmented processing systems, and the underutilization of by-products. These inefficiencies lead to economic losses and environmental burdens due to biomass waste. This study aims to develop an integrated and sustainable optimization framework for coconut processing that simultaneously enhances profitability and ensures the full utilization of coconut biomass. The framework is formulated as a Mixed-Integer Linear Programming (MILP) model that captures production interdependencies, raw material constraints, and facility capacity limitations across multiple processing units, including oil extraction from coconut fruits, charcoal production from coconut shells, and flour processing from coconut pulp. The model implementation demonstrates the viability of integrated production planning, with optimal facility activation and complete utilization of coconut derivatives, in line with circular economy principles. These findings highlight the potential of the proposed model as a robust decision-support tool for improving sustainability and efficiency in coconut-based agro-industry.

Abstract

Inventory of raw materials is very important for the smooth production of the company and meet consumer demand for the company in market demand. The demand for tire production fluctuates and causes the demand for products not to need to be met to order, due to the shortage of raw materials. To solve the shortage of raw materials, the company holds special orders in consideration of savings in ordering the cost of ordering messages. To overcome the shortage of raw materials, the company holds special orders or sudden orders which will increase the cost of the message. The purpose of this study is to determine the optimum ordering of raw materials to minimize total inventory costs by using a probability model of raw material inventory control with a fixed order quantity system (Q method). From the results of research using the probabilistic model of inventory control method Q method, obtained the optimal order quantity (q*), reorder point (rop), and safety stock (ss) with total inventory costs more efficient compared to the total inventory costs of the company's current policies. what is to be achieved in inventory control is to minimize the cost of ordering, and the cost of savings to the company.

Abstract

Redaman viskus memiliki peranan penting dalam pengendalian getaran mekanik dengan mengonversi energi osilasi menjadi energi panas melalui fluida pelumas. Penelitian ini menyajikan evaluasi eksperimental pengaruh tingkat viskositas oli terhadap karakteristik peluruhan amplitudo pada sistem massa–pegas–peredam yang berosilasi bebas. Empat oli komersial digunakan sebagai variabel redaman, yakni SAE 20, SAE 40, SAE 60, dan SAE 140. Parameter utama yang diamati meliputi pengurangan logaritmik (δ), rasio redaman (ζ), dan persentase peluruhan amplitudo dalam beberapa siklus osilasi. Hasil memperlihatkan adanya peningkatan yang konsisten pada kemampuan redaman seiring kenaikan viskositas; nilai ζ meningkat dari 0,08 (SAE 20) menjadi 0,18 (SAE 140) dan persentase peluruhan amplitudo dari 8,02% menjadi 17,10%. Temuan ini menegaskan bahwa pemilihan viskositas fluida merupakan parameter desain kunci untuk meningkatkan disipasi energi pada sistem redaman viskus di berbagai aplikasi, termasuk suspensi kendaraan dan peredam industri. Abstract: Viscous damping plays a crucial role in controlling mechanical vibrations by converting oscillatory energy into heat energy through a lubricating fluid. This study presents an experimental evaluation of the effect of oil viscosity on the amplitude decay characteristics of a freely oscillating damper–spring–mass system. Four commercial oils were used as damping variables, namely SAE 20, SAE 40, SAE 60, and SAE 140. The main parameters measured include logarithmic decrement (δ), damping ratio (ζ), and percentage decay amplitude over several oscillation cycles. The results show a consistent increase in damping capability with increasing viscosity; the ζ value increases from 0.08 (SAE 20) to 0.18 (SAE 140), and the percentage decay amplitude from 8.02% to 17.10%. These findings confirm that fluid viscosity selection is a key design parameter for improving energy dissipation in viscous damping systems in various applications, including vehicle suspension components and industrial dampers.
