Abstract

The surge in LPG consumption within Indonesian households, coupled with stagnant LPG production, has compelled the government to import 75% of LPG by 2022. Despite initial plans for a transition to electric stoves in 2023, the program was halted due to widespread public resistance to electric stove technology. The rejection was attributed, in part, to low trust in this emerging technology, emphasizing the pivotal role of trust in influencing technological acceptance. In response, this research endeavors to construct a robust and reliable model capturing trust in the acceptance of electric stove technology. Utilizing the PLS Structural Equation Model method for data analysis, the focus centers on two trust indicators: propensity trust and human-machine trust. In the quest for a valid model, the statistical modeling technique considers five initial hypotheses developed with 32 trust-related items. Upon analysis, one hypothesis is rejected, while four are accepted. Notably, the trust human-machine (THM) variable emerges as a significant influencer of trust for electric stove technology (TTK), substantiated by a path coefficient of 0.917 and p = <0.001. Thus, the resulting model takes on a reflective form, offering insights into the intricate dynamics of trust in the acceptance of electric stove technology.

Abstract

This study analyzes the queuing system at XYZ fast food restaurant in Batam City to improve service efficiency and customer satisfaction. Observations were conducted over eight hours on Saturday, April 6th, 2024, from 2:00 PM to 10:00 PM. Data collected included arrival patterns, service time, and customer wait time. Using the queuing model [M/G/2/FIFO/4/∞], it was found that two servers are optimal. The average customer wait time in the system is 4.938 minutes, which is lower than the customer's aspirational wait time of 10 minutes. The system's utility reached  84.33%, indicating sufficient efficiency. Practical recommendations for XYZ fast food restaurant management are to maintain two servers to reduce wait time and increase customer satisfaction.

Abstract

PT. XYZ merupakan sebuah perusahaan yang beroperasi di sektor manufaktur ban vulkanisir. Hasil dari proses manufaktur ini adalah lembaran ban dengan variasi pola bunga ban. Penempatan 28 jenis produk yang tidak teratur dan terpisah, tanpa lokasi penyimpanan tetap dan alokasi ruang gudang yang jelas, berdampak pada peningkatan waktu dalam proses identifikasi dan pengambilan produk sesuai jenis dan karakteristiknya. Hal ini menyebabkan biaya operator meningkat dan efisiensi ruang gudang berkurang. Pola susunan karet pre-curedtread menjadi tidak teratur dan tidak cocok dengan dimensi dan ukuran barang tersebut. Pendekatan penyimpanan berdasarkan kelas digunakan untuk menyusun dan menempatkan produk sesuai dengan kategori material, produk, dan bahan pembuatannya yang serupa. Hasil akhir menunjukkan pengurangan jarak pengambilan produk dari 448 meter menjadi 130,81 meter. Waktu pengambilan produk juga mengalami penurunan dari 309,2 menit (setara dengan 5,15 jam) menjadi 64,01 menit (setara dengan 1,06 jam).

Abstract

PT. XYZ merupakan sebuah perusahaan manufaktur yang berfokus pada produksi komponen mesin dari baja cor untuk berbagai keperluan industri, termasuk pertambangan, kelapa sawit, peralatan berat, dan industri karet. Salah satu produk yang menjadi fokus penelitian adalah jaw plate, yang menjadi produk dengan permintaan tertinggi di pasaran dibandingkan dengan produk lainnya. Penelitian ini bertujuan untuk mengatasi ketidaksesuaian antara jumlah produk yang dipasok dengan permintaan di Distribution Centre (DC) Aceh dan DC Jambi, yang berakibat pada kekurangan stok produk di DC tersebut. Pendekatan yang digunakan adalah perencanaan kebutuhan distribusi menggunakan metode Distribution Resources Planning (DRP) dan Model Economic Order Quantity (EOQ) untuk menentukan ukuran pemesanan yang ekonomis. Hasil penelitian menunjukkan bahwa untuk DC Aceh dan DC Jambi, ukuran pesanan yang ekonomis (q) adalah 136 unit dan 109 unit, dengan stok keselamatan (ss) sebanyak 4 unit dan 8 unit, serta titik pemesanan ulang (reorder point, r) sebanyak 24 unit dan 17 unit.

Abstract

Beauty care and the need for cosmetics have become the lifestyle of modern women, especially in big cities. Public awareness to look beautiful makes modern women competing to take care of themselves to be more beautiful. The body care industry in Indonesia continues to grow. The growth has reached 6% and is predicted to continue to grow along with the high concern of Indonesian women in caring for their skin. To win the competition, companies need to know the market and consumer situation. One strategy that can be applied by the company is to use a promotional or advertising strategy. This research was conducted at the Ariana Audy beauty clinic in 2022 with the aim of identifying customer buying patterns which will then be used as reference material in the development of promotional menus for products and services offered by the beauty clinic. The approach used to design components on the promotional menu is Market Basket Analysis by applying the fp-growth algorithm using rapid miner software. Market basket analysis is focused on finding relationships between products based on customer purchases. The market basket analysis conducted resulted in 5 association rules that define consumer purchasing patterns for products and services provided by the Ariana Audy clinic. Through the 5 association rules formed, 3 promotional menus were produced, namely menu 1 consisting of baby skin crystal and oxy blue cream, menu 2 consisting of brightening cream products and sunscreen brightening, and menu 3 consisting of oxy jet peel and photodynamic therapy.
