Abstract

Bisnis drone di Indonesia sudah mulai berkembang pesat, baik drone yang digunakan untuk fotografi, pemetaan, ataupun penyemprotan.  Kajian studi kelayakan bisnis rental drone merupakan hal yang penting agar dalam pengambilan kebijakan untuk percepatan komersialisasi menjadi tepat sasaran. Tujuan penelitian adalah menilai kelayakan bisnis rental drone di Indonesia pada aspek teknis, pasar dan bisnis. Metode yang digunakan pada penelitian ini menggunakan pendekatan model komersialisasi Goldsmith. Didapatkan hasil penelitian bahwa pada aspek teknis telah dilakukan analisis regulasi penggunaan drone, proses bisnis rental drone, model bisnis yang dapat digunakan. Pada aspek pasar dilakukan analisa pemetaan kebutuhan market dan target market. Aspek bisnis dilakukan analisa kelayakan investasi dengan metode Payback Period, dan diperoleh hasil perhitungan kelayakan investasi ini dengan jangka waktu pengembalian modal selama 3 tahun 7 bulan. Maka dari studi kelayakan bisnis rental drone ini dikatakan layak secara teknis, pasar dan bisnis.

Abstract

PT. XYZ is a manufacturing company with its production, namely bearings, both from small to large sizes. The growth of bearing sales interest is increasing every year, therefore PT XYZ must be able to adjust to the needs of consumers. This causes many types of bearings that must be produced by PT XYZ, this type change affects the time in the machine change over process. This research was carried out with the aim of reducing the time used for the machine change over process, especially on the chage press machine which has been seen through patchwok data. The improvements made are by using the PDCA and SMED methods, to be able to find out what factors are the cause of the long change over and also how to reduce the time in the change over process of the machine, With the implementation of SMED PT. XYZ managed to reduce the time from 1 hour 9 minutes 56 seconds to 9 minutes 1 second with a time reduction of 1 hour 55 seconds or equivalent to 87.85%. Thus, this SMED method can be used to improve engine change time to make it faster.

Abstract

The FMCG manufacturing industry faces complex challenges in the supply chain, where supplier performance evaluation is a crucial factor in maintaining production continuity. PT XYZ currently conducts supplier evaluations in a general manner without considering specific segmentation, making it less effective in identifying strategic suppliers and managing risks. The Purchasing portfolio matrix classifies raw materials into strategic, leverage, bottleneck and non-critical groups based on supply risk and profit impact. Meanwhile, the Supplier Potential Matrix (SPM) adds the dimensions of supplier capability and willingness in innovation and collaboration. The combination of these two methods can enhance the effectiveness of supplier evaluation, support procurement strategies, and ensure more optimal business relationships. The weighting of each criterion will be carried out using the Best-Worst Method. Next, the scoring process is conducted based on 13 agreed criteria for each evaluated supplier, totaling 148 suppliers. The results of data processing will be used for segmentation using a hybrid PPM-SPM model. Recommendations are provided for selecting the appropriate supplier relationship management strategy for each supplier segment.

Abstract

In today’s competitive manufacturing industry, maintaining high production efficiency and minimizing machine downtime are critical challenges, particularly in the food sector. This study aims to analyze the effectiveness of ten CBP product packaging machines at PT. XYZ using the Overall Equipment Effectiveness (OEE) method. The research employs a quantitative approach based on primary data collected through direct observation and interviews. The OEE method measures machine performance through three indicators: Availability, Performance, and Quality. The results show that the average OEE value from October to December 2023 is 94%, exceeding the world-class standard of 85%. The dominant loss affecting effectiveness was Equipment Failure Losses (50%), followed by Rework and Defect Losses (22% each). These losses are primarily caused by machine wear, material issues, and operator handling errors. The findings indicate that the OEE method serves as an effective tool for monitoring production efficiency and planning preventive maintenance. Regular operator evaluations and standardized maintenance procedures are recommended to sustain high equipment performance levels.
