Abstract

PT Gagas Energi Indonesia is a gas subholding company, including the distribution of CNG in the form of cylinders (C-cyl). C-cyl one of the CNG development projects is packaged in a pressurized cylinder of 200-250 pcs and the volume of CNG ranges from 20 - 25 m3 with 16 - 20 kg of LPG. The problem of this research is that the route determination by the company is still done manually so that it has risks in making decisions, assumptions, causing long distances per day and causing the use of a large fleet to be able to cover all customers per day. In solving this problem, the AnyLogistix software transportation optimization model features are used which are solved with the capacited TO experiment to determine distribution routes with the characteristics of the CVRP problem. The data used are 20 location points for potential customers who have the highest demand in the industrial sector, the products used as research objects are CNG C-cyl gaslink and 125 PS Head Truck capacity. The results of the route in the AnyLogistix software for the delivery movement path January 1 2022 – January 5 2022 obtained the total route, the total distance is the same for each day with the first route starting from Pertamina Jaya Hospital, Grand Paragon Mall, PT SINAR HARAPAN PLASTIK, PT DELIDENT, Blok M Plaza, Mercure Jakarta Gatot Subroto, Karimata Taman Mini, Bhayangkara Hospital TK.I R. Said Sukanto, ABUBA Steak – Matraman with a total distance of 106.80 KM, the second route to Richesee Kalimalang, Pondok Kelapa Town Square with a total distance of 14.94 KM and the third route to PT. PIONIRBETON INDUSTRY, Dr. Mintohardjo Naval Hospital, Plataran Menteng, Mercure Jakarta Cikini, Best Western Plus Kemayoran Hotel, Whiz Prime Hotel Kelapa Gading, SANTIKA KELAPA GADING, Jakarta Harbor Hospital, Boutique Café with a total distance of 53.85 KM.

Abstract

Penelitian ini dilakukan untuk mengatasi masalah kecacatan produk pada PT. XYZ yang bergerak dalam produksi frozen food hasil olahan perikanan dan udang. Masalah yang dihadapi adalah adanya cacat pada kulit dimsum dan ketidakseragaman bentuk dimsum dalam proses produksi dimsum. Dalam penelitian ini, digunakan pendekatan Six Sigma dengan metode DMAIC. Hasil penelitian mengungkapkan bahwa ada dua jenis cacat pada dimsum, yaitu kerusakan pada kulit dimsum mencapai 66% dan ketidakseragaman bentuk dimsum mencapai 34%. Dengan menggunakan peta kendali p-chart, diketahui bahwa ada satu kejadian di mana cacat produk berada di luar batas kendali, sementara yang lainnya berada dalam batas kendali. Meskipun demikian, jumlah cacat produk secara keseluruhan masih melebihi nilai rata-rata cacat. Dalam perhitungan Defect Per Million Opportunities (DPMO), ditemukan bahwa terdapat 23,506.90 produk cacat per satu juta produk yang diproduksi, dengan tingkat sigma sebesar 3.51. Untuk itu, dilakukan analisis sebab-akibat menggunakan fishbone diagram dengan faktor penyebab yang teridentifikasi, yaitu material, mesin, pekerja, dan metode. Setelah analisis sebab-akibat, dilakukan perbaikan dengan metode Kepner Tregoe Potential Problem Analysis (KTPPA) dan Action Plan. Dengan menerapkan pendekatan Six Sigma dan metode DMAIC, diharapkan PT. XYZ dapat mengurangi jumlah cacat produk, meningkatkan mutu dan kualitas dimsum, serta meningkatkan efisiensi dalam proses produksi. Semoga hasil penelitian ini dapat memberikan manfaat bagi perusahaan dan industri dalam menghadapi tantangan produksi frozen food.

Abstract

Fertilizer has an important role in supporting the productivity of food crops. The Indonesian government provides subsidized fertilizers in an effort to support the fulfillment of national food needs. The number of subsidized fertilizer needs targeted by the government increases every year. Therefore, appropriate inventory planning is needed to realize the subsidized fertilizer production target that has been set by the government. The type of NPK fertilizer is one of the concerns because this type of subsidized fertilizer has a high demand rate, but its production figure is still far from the realization target. So that in this study the author aims to conduct a comparative analysis of inventory with the policies set by the company, namely Minimum-maximum with the Economic Order Quantity (EOQ) method. The EOQ method considers several costs, such as holding costs, raw material prices, and ordering costs. There are several outputs produced by the authors in this study, such as the frequency of orders, safety stock, reorder points, and total inventory costs. With this policy, the total cost of raw material inventory that must be spent for the manufacture of NPK fertilizer is Rp 4,257,606,170. And by using the EOQ method, it can save the company's total inventory cost of Rp. 121,368,688 or 2.77%.

Abstract

Capacitated Vehicle Routing Problem (CVRP) is known as an NP-hard problem. It is because CVRP problems are very hard for finding optimal solutions, especially in large instances. In general, the NP-hard problem is difficult to solve in the exact method, so the metaheuristic approach is implemented in the CVRP problem to find a near-optimal solution in reasonable computational time. This research uses the DPSO algorithm for solving CVRP with ten instances of benchmark datasets. DPSO implementation uses tuning parameters with the One Factor at Time (OFAT) method to select the best DPSO parameters. The outcome objective function will be compared with several PSO models proposed in previous studies. Statistical test using One Way Reputed Measure ANOVA is needed to compare algorithm performance. First, ANOVA uses for comparing’s results. Then, ANOVA is also used to test DPSO’s performance compared with DPSO-SA, SR-1, and SR-2 algorithm. The computational result shows that the basic DPSO algorithm not competitive enough with other methods for solving CVRP.

Abstract

The present study emphasizes mixed-method analysis, integrating the partial least square structural equation model (PLS-SEM) and customer journey for mobile pocket office improvement in logistic XYZ company. The extension of the unified theory of acceptance and use of technology (UTAUT 2) model by incorporating perceived risk (PR), personal innovativeness (PI), and trust (TR) variables are used. The sample for this study consisted of 243 res­pondents. Based on the results of the PLS-SEM analysis, two of the eleven tested hypotheses were determined to be rejected. In application usage, the proposed model effectively explained 85.7 per cent of the influence on beha­vioral intention (BI) and 72.1 per cent on use behavior (UB). The customer journey mapping (CJM) investigation's findings show that fluctuations in the use of mobile pocket office technology in the field are generally brought on by a lot of data entry, sluggish internet connections, and overworked field operations. The XYZ company may acquire sugges­tions and knowledge for developing further applications due to this inquiry.

Abstract

The productivity level of PT. XYZ is still below the target, especially in the batch area. This condition is proved by the Overall Equipment Effectiveness (OEE) value is about 58% based on January and February data. Taking this into account, it is necessary to conduct further research to determine the causes. This study aims to increase productivity in the raw material warehouse and pre-batch areas. To solve this problem we use a six-sigma with DMAIC method because these methods can determine the root cause of the problem and provide appropriate recommendations for improvement systematically. The results show that the application of the kanban system in the pre-batch area and reuse of rack in the pre-batch area can increase the average OEE batch value from 58% to 64%. The increase in productivity tn the raw material warehouse and pre-batch area affects Adherence to Plan (ATP) value from 86% to 91,15%.
