Abstract

Banyaknya Pelabuhan di Indonesia yang belum menerapkan Key Performance Indicator dalam evaluasi operasional kerjanya dan minimnya pengembangan teknologi sebagai nilai tambah dalam operasional Pelabuhan di Indonesia. Dilakukannya evaluasi dan pengukuran kinerja berdasarkan pada standar yang ada merupakan hal yang cukup penting dalam peningkatan kualitas kerja. Penelitian ini bertujuan untuk memberikan rumusan KPI dengan merujuk pada gabungan metode BSC dan PESTLE untuk meningkatkan kinerja pelabuhan. Penggabungan metode BSC dan PESTLE yang juga disertai dengan konsep sustainability, smart dan green port. Metode BSC digunakan sebagai ukuran kinerja perusahaan secara keseluruhan tetapi lebih menitikberatkan pada aspek internal perusahaan, sedangkan PESTLE digunakan sebagai ukuran kinerja pada aspek eksternal pelabuhan. Berdasarkan hasil studi literatur, metode-metode tersebut terbukti dapat digunakan sebagai alat ukur kinerja pelabuhan, sehingga perlu diintegrasikan karena perusahaan harus berada pada posisi kompetitif dengan informasi internal dan eksternal yang dibutuhkan. Oleh karena itu, penggunaan KPI yang telah dirumuskan dalam proses evaluasi kinerja Pelabuhan cukup penting untuk dilakukan.

Abstract

The projected decrease inspired this research in Afdhol MSMEs' consumer base in 2020. This study's objectives were to determine the pattern of product brand transfer for Nasional Afdhol (SNA) and predict the market share and price of prayer cap products. This study was undertaken at the SNA in Bungah District, Gresik Regency. With a population of 415 people and a required sample size of 204 persons, the required data consists of a questionnaire containing questions concerning prayer cap brand items used in the past and prayer cap brand products used presently. There are three competing prayer cap brands: Nasional ONH, Pendopo, and Nasional Gapuro Bungah. During the pandemic, it has decreased drastically by almost 70% until the last two years, so the problem that can be formulated was SNA has never evaluated the market, so competitors have never been taken into account for their role, which may affect the market share, and how consumers behave in their role in choosing which songkok to buy. By calculating using the Markov chain, the pattern of songkok purchase movement made by consumers in the 4 songkok brands can be analyzed so that SNA canplan marketing strategies to increase sales and their expected values. Data processing was performed using Rantai Markov, beginning with projecting market share using three strategies. The first strategy was without decreasing or raising prices. The second strategy was reducing the price of Rp. 5,000.00, and the third strategy was increasing the price of Rp. The calculation results yielded the greatest market share value. A formulated strategy was to cut the price of Rp. 5,000.00 by 42.65% with a probability value of 0.4265 under a steady-state condition of 0.4714 with a profit of Rp. 1,137,636. The strategy to obtain maximum expectation values has the consequence of enlarging its customer base.

Abstract

This study aimed to compare the compressive strength of various concrete brick compositions made from geopolymers using different clay precursors, including Pejaten clay (PJT), Darmasaba clay (DSB), Waste Tile clay (LG), and dam sediment clay (DAM). Laboratory tests were carried out after 7 days of curing, and the results showed that PJT was the most suitable precursor material for producing geopolymer-based concrete formulas that meet the requirements for solid brick concrete quality class I, with an average compressive strength of 119,926 kg/cm2. The average value of SNI requirements is at least 100 kg/cm2 based on SNI 03-0349-1989 for physical requirement quality standart of concrete bricks. DSB had a compressive strength of 88,808 kg/cm2 and was classified as class II, followed by LG with a compressive strength of 76,366 kg/cm2 and DAM with an average compressive strength of 70.71 kg/cm2, both of which belong to class II. These findings provide valuable insights into the use of different clay precursors for the production of high-quality concrete bricks.

Abstract

The high overtime cost for nurses from Manual Scheduling, in the inpatient unit at ABC Hospital, where the overtime cost was Rp.10,409,910,-, much the difference number working hours between each nurses and many violations of hard constraint. So, it is necessary to make improvements to the scheduling. This study developed the scheduling whose goal is to minimize violations of regulations and minimize overtime costs by Goal Programming (GP). Mathematical formulation for both objectives were solved by LINGO 18.0. The difference in the number of working hours between the highest working hours and the least working hours for nurses who are not on leave, on Manual Scheduling, The Minimizing Regulatory Violations Scheduling and The Minimizing Overtime Costs Scheduling were 53, 0 and 1 hour(s) respectively. The highest number of working hours was 221 hours in Manual Scheduling, while the least number working hours was 175 hours in Minimizing Overtime Scheduling. If the policy in scheduling wanted to minimize violations, using the result of Scheduling for Minimizing Violation of the regulations there were 177 violations and overtime costs was Rp. 3.652.600,- reduced by 64.91%. Meanwhile, if the Hospital wanted to minimize overtime costs, using the result of Scheduling Minimizing Overtime Costs, there were 246 violations and overtime costs was Rp.104,360,- reduced by 99.0%.In the future, the hospital must establish a policy in terms of scheduling, whether the aim is to minimize violations of regulations or minimize overtime costs, so that based on this policy, the mathematical formulation can be determined.

Abstract

The development of technology in industry 4.0 era leads to a digitalization process which is marked by the emergence of the internet as one of the important enablers. Indihome and Firstmedia are the most popular Internet Service Providers) ISPs in Indonesia in providing internet services. These two companies certainly have competition in winning the hearts of customers. One of the important factors in this business competition is customer response in the form of reviews which are usually done through social media tools such as Twitter. For this reason, it is important to study how the customer responds in the form of a given sentiment. Sentiment analysis can be a way to study customer responses to products and services. Sentiment Analysis is a method that is part of Big Data in Data Science which is useful for assessing sentiment in the form of positive or negative sentiments. The data collected was 1000 tweets for each ISP which will be processed with the help of Rstudio. The processing results obtained 177 positive tweets, 489 neutral, and 334 negative tweets for indihome while firstmedia obtained 620 positive tweets, 222 neutral tweets, and 158 negative tweets. The result is firstmedia ISPs get a better positive response and the number of complaints is less than indihome. Internet service providers (ISPs) can improve product and service quality by creating a single database system and also implementing the service design blueprint.

Abstract

This study aims to understand the supply chain strategy of pharmaceutical companies, logistics drivers (facilities, inventory, and transportation), and cross-functional drivers (information, sources, and prices), as well as the problem of placing safety stock for assembly, using an integer linear approximation program using CPLEX to get the results and perform a sensitivity analysis. In this way, the effect of various parameters on total safety stock and service time can be estimated. Pharmaceutical companies can find strategic ways to align their goals with this method. The company already has an optimal supply chain focused on product quality, short response times, and product availability. In addition, it can minimize the total cost of safety inventory by using a piecewise linearization approach with a total assembly cost of Rp. 6,161,120,000, where safety stock is stored in stages 2-4, 7-14, 16, and 22, where 22 has the highest stage costs. Then a sensitivity analysis is carried out by allowing the parameters to vary, the more segments' total cost becomes stable. Furthermore, the relationship between the factors of safety, storage costs, and standard deviation is linear.
