Abstract

Lingkungan bisnis yang semakin ketat dan kompetitif menuntut perusahaan untuk menyesuaikan diri pada setiap perubahan yang terjadi serta siap menerima semua tantangan yang ada. Keberlangsungan suatu optik terletak pada keberhasilan optik tersebut membawa para konsumennya tetap setia melakukan pembelian ulang kacamata resep untuk keberhasilan rehabilitasi refraksi. Penjualan optik XYZ masih jauh berada dibawah para kompetitornya sehingga perlu merumuskan strategi yang tepat agar dapat meningkatkan niat beli ulang. Tujuan penelitian ini adalah untuk mengetahui dan menjelaskan apakah ada pengaruh atribut produk, pengalaman konsumen dan nilai yang dirasakan terhadap niat beli ulang. Pengambilan sampel menggunakan teknik non probability sampling yaitu sebanyak 126 reseponden diolah menggunakan path analysis dengan bantuan Smart PLS versi 4.0. Experiential marketing theory dipilih sebagai pisau analisis pada penelitian ini. Hasil penelitian menunjukkan bahwa variabel atribut produk, pengalaman konsumen dan nilai yang dirasakan berpengaruh terhadap niat beli ulang serta kepuasan konsumen terbukti secara statistik mampu memediasi pengaruh atribut produk terhadap niat beli ulang. Optik XYZ diharapkan mampu untuk terus memberikan kelengkapan produk yang akan memberikan nilai ekslusivitas yang diharapkan oleh konsumennya agar niat untuk membeli ulang semakin meningkat dari waktu ke waktu. An increasingly tight and competitive business environment requires companies to adapt to every change and be ready to accept all existing challenges. An optic's sustainability lies in its success in bringing its consumers to remain loyal in repurchasing prescription glasses for successful refractive rehabilitation. XYZ optical sales are still far below its competitors, so it is necessary to formulate the right strategy to increase repurchase intentions. This research aims to find out and explain whether product attributes, consumer experience, and perceived value influence repurchase intention. Sampling used a non-probability sampling technique; 126 respondents were processed using path analysis with the help of Smart PLS version 4.0. Experiential marketing theory was chosen as the analytical tool in this research. The research results show that the variables of product attributes, consumer experience, and perceived value influence repurchase intentions, and consumer satisfaction is statistically proven to mediate the influence of product attributes on repurchase intentions. Optik XYZ must be able to provide complete products that will provide the exclusivity value expected by consumers so that their intention to repurchase increases over time.

Abstract

Program Rusunawa Mahasiswa merupakan upaya pemerintah mewu­judkan pemerataan dan peningkatan kualitas pendidikan di perguruan tinggi. Di­harapkan dengan adanya Rusunawa Mahasiswa, biaya sewanya lebih murah dibanding harga sewa kos-kosan. Diharapkan pula, pihak kampus sebagai penge­lola Rusunawa Mahasiswa bisa memprioritaskan mahasiswa kurang mampu dari luar kota yang memiliki prestasi akademik b a g u s , sehingga mereka terbantu dari aspek ekonomi. Sampai saat ini masih ada kesenjangan antara target dan realisasinya pembangunan Rusunawa Mahasiswa. Kesenjangan dapat terjadi karena berbagai faktor, antara lain berupa inkonsistensi regulasi maupun inkon­ sistensi implementasi. Penelitian ini merupakan penelitian yang bersifat yuridis-normatif. Penelitian ini dilakukan dengan meneliti bahan pustaka dan perundang-undangan yang relevan dan terkait dengan substansi penelitian. Data yang terkum­pul dianalisis dengan metode kualitatif. Hasil kajian menunjukkan bahwa: 1. Ada inkonsistensi regulasi berupa kekurangan peraturan pelaksanaan dalam bentuk Peraturan Pemerintah dan Peraturan Menteri; 2. Ada inkonsistensi implemen­tasi disebabkan lemahnya pengawasan, kurang profesionalitas pelaksanaan dan penegakan regulasi.

Abstract

Referring to the principle of uti possidetis juris, the establishment of the boundary line on Sebatik Island was based on a previous agreement between the Netherlands and the British. It was stated in the 1915 Agreement between the Netherlands and the British, which declared that the boundary line follows a parallel line of 4º10' North Latitude. Unfortunately, The Boundary Agreement of 1915 does not mention the datum and reference ellipsoid used to determine the abovementioned 4° 10' North Latitude. The absence of a datum and reference ellipsoid causes disputes in determining the precise location of boundary pillars during the field reconstruction procedure. A joint survey between Indonesia and Malaysia in 1983 found that most of the boundary pillars on Sebatik Island were not precisely located along the 4° 10' North Latitude line and based on the results of the 10th meeting of the Joint Working Group on the Outstanding Boundary Problems in 2018, Indonesia and Malaysia agreed to re-demarcate the boundary, which was carried out in 2019. This study aims to determine the impact of the 2019 re-demarcation of the boundary line between Indonesia and Malaysia on Sebatik Island. The methods applied in this research are in-depth interviews, observation, and document studies. The results found that the 2019 re-demarcation resulted in exchanging areas between Indonesia and Malaysia. This area exchange generates uncertainty about land ownership by citizens in border zones.

Abstract

Packaging Factory have activities in  bag production. In order to increase the productivity, the company should manage the activities to increase valued added and decrease several waste. This study was purpose for analyzed the caused problems of waste, and give recommendation for minimizing the waste.  The problem solving at the study was using lean manufacturing concept approach.  The waste identification began with identification of  current state value stream mapping with weighting the waste in order to  understand the root of problem within production process.  The detail mapping selection was using Value Stream Analysis Tools (VALSAT).  Root Cause Analysis was used in order to understanding the root of problem for production process followed by FMEA for understanding the improving priority which has to be done. From the data analysis result, we found that the most dominant waste order is defect, waiting,  inventory, excessive transportation.The mapping detail used for analysis process as Process Activity Mapping Supply Chain Response Matrix and Quality Filter Mapping. From the result of study we found the decreasing of production time from 138.4 minute to 119.4 minute.  Decreasing lead time process could reach 13,7% comparing before the recovery step.

Abstract

Performance measurement method, Performance Prism, was used to improve performance measurement method in this furniture company. Until now, performance measurement system in this company  haven’t represented overall organizational performance since it only used performance measurement based on individual ability. Performance measurement using Performance Prism method was used because it could reflects the needs and desire of each identified stakeholder within company. This performance measurement is an integrated measurement, encompassing all company aspects (stakeholder) which related with stakeholder satisfaction and stakeholder contribution for the company. Performance measurement in this study also supported by several other methods such as weighting with Analytical Hierarchy Process (AHP) to determine priority scale of each KPI, Scoring System using Objectives Matrix (OMAX) and Traffic Light System to determine total index value of company in corporation level and category of those indices. Results of performance measurement in this company using Performance Prism indicated 79 KPI’s consist of 17 KPIs on Investor perspective, 16 KPI’s on Customer perspective, 16 KPI’s on Employee perspective, 15 KPI’s on Supplier perspective and 15 KPI’s on Regulator perspective. Based on performance measurement calculation using Objective Matrix and Traffic Light System, it obtained total index value 5,8364. This showed that performance of this furniture company  still yet to reach desirable performance thus it would need some improvement in this matter.

Abstract

A paper company produces many kind of papers where notebooks are its main products. The production approach is make to order. At the completion of the production processes indicates delays due to long lead times. Long lead time of production reduces the company's flexibility and speed of response to customers. The company should shorten the lead time. Shortening lead time, the speed customer response will be faster, the productivity will be increasing and utilization of production resources will more effective. This study propose the use of Value Stream Mapping (VSM) method to overcome it. VSM will identify wastes that can be eliminated, so the company can reduce production costs, meet customer demand, and also increase the company's revenue and market share. The observation identifies wastes in the HC Folio production processes, such as waiting, transportation and unnecessary inventory. Based on the significant wastes, it proposes some improvements to repair the transportation and waiting wastes. To handle work in process parts, the study recommends to implement of rails and trains. It will reduce production time that decreases from 66,828 hours 49 minutes 48 seconds to 30,938 hour 56 minutes 24 seconds.

Abstract

Paiton Unit 1, 400 MW power plant, has been the subject of a detailed performance analysis utilizing modelling and simulation techniques employing GateCycle software. This study encompasses an evaluation of the impact of variations in main steam pressure, condenser pressure, and main steam temperature on key performance parameters, including thermal efficiency, heat rate, condenser duty, and power generation. The model underpinning this analysis was developed based on the heat balance scheme of Paiton Unit 1 PLTU, and its validity was confirmed through validation using operational data. The simulation results demonstrate that an increase in main steam pressure and temperature leads to enhanced thermal efficiency and output power of the plant, while an increase in condenser pressure results in reduced efficiency and net power generation. A decrease in condenser pressure increases the pressure difference between the turbine and condenser, thereby facilitating greater energy conversion to mechanical power. Heat rate analysis reveals that the heat rate value decreases with increasing main steam pressure and temperature and decreasing condenser pressure, indicating an increase in system efficiency. This study validates the hypothesis that optimization of key operational parameters at Paiton Unit 1 PLTU can enhance plant efficiency and reduce fuel consumption, thereby providing both technical and economic benefits.
