Abstract

Industri plastik merupakan salah satu sektor manufaktur terbesar di dunia, menyediakan berbagai produk yang digunakan dalam kehidupan sehari-hari, mulai dari kemasan makanan, komponen otomotif, hingga barang elektronik. Proses ekstrusi adalah salah satu metode utama dalam produksi barang-barang plastik. Dalam proses ini, bahan baku plastik dilelehkan dan didorong melalui cetakan untuk membentuk produk akhir. Keberhasilan proses ekstrusi sangat dipengaruhi oleh berbagai parameter operasional, salah satunya adalah suhu. Suhu yang terlalu rendah dapat menyebabkan bahan tidak meleleh sempurna, mengakibatkan aliran yang terhambat dan produk dengan kualitas buruk. Sebaliknya, suhu yang terlalu tinggi dapat menyebabkan degradasi termal, yang juga berdampak negatif pada kualitas produk dan umur mesin. Penelitian ini bertujuan untuk menganalisis pengaruh suhu terhadap laju aliran plastik pada mesin extruder. Metode yang digunakan mencakup pengumpulan data eksperimental, analisis data, dan validasi hasil dengan model teoretis. Desain penelitian ini bersifat eksperimental dengan pendekatan kuantitatif. Hasil pengujian menunjukkan bahwa, dibandingkan dengan peleburan pada suhu 150°C, mesin ekstruder plastik yang menggunakan pelet plastik yang dilelehkan pada suhu 300°C lebih berhasil dalam menghasilkan filamen dengan diameter dan bentuk yang baik. Filamen yang dipanaskan dengan pemanas selama satu menit pada suhu 300°C menghasilkan berat akhir 26 gram, namun selama satu menit pada suhu 150°C hanya menghasilkan satu gram. Selanjutnya perhitungan debit pada suhu 150°C menghasilkan hasil akhir sebesar 1 gr/m, sedangkan perhitungan debit pada suhu 300°C menghasilkan hasil akhir sebesar 26 gr/m.

Abstract

In facing competition in the current era of globalization, one of the efforts made by the company is to increase the productivity of its employees. This study aims to analyze the workload of workers at PT. Indofood CBP Sukses Makmur Tbk Medan Branch in the spare part warehouse section. The workload analysis method with work sampling is used to collect work and idle data from employees in the spare part warehouse. From the calculation results, the workload in shift-1 is quite high, while in shift-2 and shift-3 it is still not high enough so that it can still be optimized. The proposed improvement is to shift some of the work in shift-3 to shift-2 and eliminate employees in shift-3 by turning on other employees whose work locations are closest and allow them to handle work in the spare parts warehouse in shift-3

Abstract

The Indonesian logistics industry is undergoing rapid digital transformation through the adoption of artificial intelligence (AI), Logistics Information System (LIS) integration, and Warehouse Management Systems (WMS). However, empirical studies examining the simultaneous effects of these technologies on operational efficiency and customer satisfaction remain limited. This study investigates the influence of AI implementation, LIS integration, and WMS adoption on operational efficiency and customer satisfaction in Indonesian logistics companies. A quantitative explanatory research design was applied using purposive sampling. Data were collected from 350 respondents, including logistics managers, warehouse supervisors, IT managers, and supply chain coordinators across Indonesia. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4. The results show that AI implementation, LIS integration, and WMS adoption have positive and significant effects on operational efficiency. Operational efficiency also significantly improves customer satisfaction. Among the three digital technologies, AI implementation has the strongest standardized effect, followed by LIS integration and WMS adoption. The findings confirm that operational efficiency plays a crucial role in linking digital technology adoption with customer-related outcomes. This study contributes to TAM, RBV, TOE, and Digital Transformation Theory and provides practical insights for improving logistics performance.

Abstract

The results of experimental research on marine thermal power plants using a shell and tube heat exchanger made of copper-tin (Cu-Sn) alloy are the main focus of this study. This study uses a heat exchanger Scale Model measuring 60 mm wide x 1 meter long. The system operated using a closed cycle and Organic Rankin cycle. A simulation study has been carried out using Ansys CFD software to model new heat exchangers, namely models A and B. The interaction between ammonia and hot water produces thermodynamic values in the form of an evaporator outlet temperature of 28°C in models A and B 260C. The weakness of model B is that the turbulent flow is divided into left and right sides so that heat loss occurs in the flow corner area. The seawater inlet temperature of 29°C can heat the working fluid from the ammonia flow inlet from 5°C to 28°C, resulting in saturated steam reaching 5-6 bar.

Abstract

Food security remains a major challenge for Islamic boarding schools with limited land and resources. This community service program aimed to optimize the use of vacant land at the Markaz Penghafal Al-Qur'an of Yayasan Layar Dakwah to improve food security. The implemented methods included raised-bed preparation, selection of superior seeds, and efficient crop maintenance. The results showed that proper land utilization increased food productivity while reducing dependence on external food supplies. Tomatoes achieved the highest productivity at 2.25 kg/m², followed by chili peppers at 1.75 kg/m² and shallots at 1.25 kg/m². To increase the added value of the harvest, female students received training on processing tomatoes into tomato sauce with a longer shelf life, as well as product packaging and marketing techniques. The program enhanced students' skills in post-harvest processing, enabled them to produce value-added products, and created entrepreneurial opportunities that can generate additional income while supporting the food security of the Islamic boarding school.

Abstract

Quality plays a very important role in reducing production costs, because the lower the number of defective products, the lower the production costs incurred, which can maximize the profits obtained. One way to maintain the quality of the products produced is by establishing quality standards, as having these standards shows that the company takes full responsibility for the products they produce. The animal feed company PT. Leong Hup Jayaindo provides several types of animal feed, one of which is broiler chicken feed 9203 LH in pellet form. Not all animal feed productions are 100% successful. The daily production is 36,250 kg, and about 32 sacks experience damage. The damage standard set by the company ranges from 0.1% to 1%. Because the products produced are diverse and quality control is considered very important, the author is interested in conducting research on quality control of animal feed products using the Statistical Quality Control method.
