Abstract

Tomat (Solanum lycopersicum L.), sebagai komoditas hortikultura, memiliki nilai gizi yang tinggi dan berbagai manfaat kesehatan. Namun, tomat rentan terhadap kerusakan dan fluktuasi harga. Salah satu alternatif yang dapat diambil adalah mengolah tomat menjadi saus. Dalam rangka meningkatkan produksi pengolahan saus tomat, diperlukan mesin pengolah tomat yang efisien. Penelitian ini bertujuan untuk merancang dan menguji kinerja prototipe mesin pengolah tomat menjadi saus tomat, serta menganalisis tekno ekonomi dari produksi saus yang dihasilkan. Prototipe mesin yang dibuat memiliki dimensi 50 x 40 x 120 cm dan dapat mengolah 5 kg tomat setiap prosesnya. Waktu optimal yang dihasilkan adalah 5 menit untuk setiap 5 kg produksi. Hasil uji kadar logam menunjukkan bahwa saus tomat yang dihasilkan memenuhi standar SNI 01-2896-1998. Dari analisis tekno ekonomi, Break Even Point (BEP) terletak pada tingkat produksi 17 kg saus tomat. Penelitian ini diharapkan dapat memberikan kontribusi positif dalam pengembangan agribisnis tomat dan industri pengolahan produk turunannya.

Abstract

World Cleanup Day gives positive impact to environmental care activities in Indonesia. Environmental Services of Batam participated into World Cleanup Day action by sorting waste from public residence in 2021. In the year of 2024, Batam still involved in World Cleanup Day action. One of the location was Tanjung Bemban, Nongsa. The purpose of this social service is to partipate in world clean up day by cleaning up the waste in Tanjung Bemban beach. The method is application of participatory approach. There are two steps in this action. The first step is introduction and preparation that conducted by committee of World Cleanup Day. Whereas, the second step is clean up the waste in the specified locations. The waste classified into four categories. Participants collected and weighted the waste to the committee. Beach Cleanup Day 2024 in Tanjung Bemban can collected waste around 235.3 kilograms, consist of 97.3 kilograms organic waste, 88.4 kilograms plastic waste and 49.6 kilograms other type of waste. This action also involved many participants from various parties, such as government, military, NGOs, universities and schools. Beach clean up action expected to increase practice in waste management.

Abstract

This study is motivated by the importance of efficiency in material handling within warehouse logistics systems, which is influenced by physical factors, particularly the coefficient of friction of floor surfaces. The objective of this research is to analyze the effect of the coefficient of friction on pushing force and the operational efficiency of material handling in warehouses. The method employed is a direct experimental approach by moving a 10 kg load using a trolley over a distance of 5 meters on three types of surfaces: ceramic, wood, and carpet. Each treatment was repeated 20 times. The observed variables include pushing force, travel time, work, efficiency, and coefficient of friction, which were subsequently analyzed using descriptive and inferential statistics. The results indicate that an increase in the coefficient of friction significantly increases the required pushing force and travel time, while reducing system efficiency. The ANOVA test produced a significance value of 0.000 (<0.05), indicating a significant difference among the surface types. Furthermore, Pearson correlation analysis revealed a very strong relationship between the coefficient of friction and pushing force (r = 0.990). Ceramic surfaces yielded the highest efficiency compared to wood and carpet. The study concludes that selecting floor materials with a low coefficient of friction can significantly improve the operational efficiency of material handling in warehouses, making it an important consideration in logistics system design.
