Abstract

Abstract. The Government has issued Undang-Undang No. 33 Tahun 2014 tentang Jaminan Produk Halal (UU JPH). The essence of the Act is article 4, The Government guarantee that all products circulated and traded in the territory of Indonesia must be "Halal" certified. The issuance of this law is very logical, considering that the majority of Indonesians are Muslim. In Islamic teachings, there are terms "Halal" and "Toyyib" that are one unity. Thus, every things consumed by Muslims should be "Halal" and "Toyyib". Beginning with this, the researcher tried to do research on the concept of "Halal" and "Toyyib" is associated with the theory of Operational Management. In the beginning, the researcher defined “Halalan-Toyyiban” Standards in poultry slaughtering. This standards are obtained from a regulation from MUI coupled by 2 regulations from Farming Department of Bandung City. Then, the researcher identified the real condition about chicken slaughtering process and layout in 10 points from 5 traditional markets in Bandung City. The researcher then compared these ideal and real conditions. The researcher found that there gaps between these conditions. Then the researcher analyzed these gaps. The researcher found that the main problem is layout. Based on the problems found above, the researcher proposed a layout as a solution. This layout is developed from "Halalan-Toyyiban" standards before. This layout consist sequence of process. Underneath there is a flow chart as the workers’ instruction.

Abstract

Basically, Forecasting is one of important things the running of a business. In addition, forecasting makes business continuity efficient. There are several factors that determine sales of our business. In the field of fashion trend is a considerable influence, but we still have to determine how many items are effective for us to produce until they run out. Clarents company is a company that sells cardholders, this company is categorized as Small Medium Enterprise. This company previously always used the Rule of Thumb system in its forecasting process. The problem that is always experienced by this company is the accumulation of unsold products. This causes the profit obtained is not in accordance with the specified target. Analysis using 3 months past demand was used to determine the forecasting method. It turns out the most suitable forecasting demand for 6 slot, 12 slot and 24 slot is Time Series Decomposition Multiplicative method, which the method has the lowest MAPE, MAD, MSD. And for the new method we can minimize of lost sale. For model 6 slot we can reduce of lost sale from 62 to 32, for model 12 slot from 124 to 74, and for the 24 method we can reduce of lost sale from 304 to 180. By using this method, we can prepare how many items we have to produce in the future.

Abstract. This research is aimed to maintain the inventory level in a two-echelon pharmacy company. The company is a pharmacy company that has 16 branches that operate in Bandung and the surrounding area. The company has a problem with its high inventory cost. To solve the problem, the authors compare two methods that suit the company condition, i.e., the decentralized system using probabilistic EOQ model and the centralization system using the multi-echelon inventory technique. We analyzed sales data and on-hand inventory data acquired from the company information system to perform the study. We limit the scope to the class A items only. We also assume the lead time, setup cost, and holding cost used in this study with the company's owner's consent. To conclude, using the decentralized system, the company will save 31% of their inventory cost, while using the centralization system with the multi-echelon technique, the company will be able to save 61% of their inventory cost. We recommend the company to refer to its competitive strategy before deciding which model it would be implemented.

Abstract

Mineral mining is performed globally, and mineral demand is continually growing in accordance with human necessities. Especially for Tin, the global tin market to grow at a CAGR of 0.81% during the period 2017-2021. PT. TIMAH Tbk, a state-owned company, operates the official tin mine on Bangka and Belitung Islands. The number of tin ingots is produced based on the RKAP or the planning master for PT. Timah Tbk. This research aims to get the well-performing forecasting method to make the estimation of tin ingots sales.After analyzing the target and realization from 2009-2020, there several error between them with the specification MAD 7,291, MSD 123,983,550, and MAPE 18.1%. This error indicates that the target and realization have 18.1% different. In this research, there are several methods used to get the better forecasting method with lowest error. The methods conducted are based on (Nahmias & Olsen, 2015) time-series method analysis and causal method. The time-series analysis used are 4-Year Moving Average, Single Exponential Smoothing, Holt’s Model, and Winter’s Model. Furthermore, the causal method used are exercised by Support Vector Machine (SVM). The demand data used are based on sales of refined tins (tin ingots) from 2009-2020.The result shows that SVM method or causal method has become the forecasting method with lowest forecast error with detail MAD 3,084, MSD 29,360,790, and MAPE 8.9%. This forecasting method is performing well because the factors used that affect the demand of tin in Indonesia have theoretically passed the correlation test (Safitri, 2004).Keywords: Forecasting method analysis, tins company, PT.

Abstract

Small and medium enterprises (SMEs) provide a significant contribution to the economy and are amongst the target of governments’ digital transformation programs. Yet, existing advanced technology adoption models are based upon and targeted for large-scale companies and might not be applicable to the majority of firms in this segment. To address this issue, this study aims to explore ways in boosting the adoption of technologies relevant to SMEs by employing a qualitative research approach through in-depth interviews and focus group discussions with manufacturing SMEs in the fashion industry. Evidence of this study points to several main findings: (1) Leader's competencies, technology literacy, growth mindset, and supportive SME conditions provide positive sentiments towards emerging technologies. However, (2) SMEs must also consider the compatibilities of the technology and evaluate its advantage to the firms prior to adoption. Lastly, (3) stakeholders support and competitors influence are also shown to affect SME leaders, the SME, and the technology itself in terms of supporting technology adoption. This research contributes to the literature by uncovering current condition and needs of SMEs for their technological transformation. For relevant stakeholders, targets of transformation might be achieved if the particular concerns of SMEs have been addressed.

Abstract

The aviation industry has an important role in connecting different regions of the world. Along with the economic recovery after the COVID-19 pandemic, improving airport performance is important to pay attention to. This research aims to design a knowledge-based performance management system that is suitable for airport companies. This research aims to identify critical factors that affect the performance of airport companies, identify organizations with critical functions, and design an integrated performance management system (IPMS) based on predetermined variables. This study uses a combination of theoretical analysis methods and model validation using data from airport companies in Indonesia. Data collection was carried out through questionnaire surveys and interviews. The Analytical Hierarchy Process (AHP) is used to select the appropriate variables by determining their level of significance. This study identifies 9 critical factors that must be considered in designing a performance management system for airport companies. These factors include business perspectives, internal processes, and resource capabilities. Furthermore, this study designs an integrated performance management system (IPMS) by determining Key Performance Indicators (KPIs), Cascade KPIs, targets, weights, and organizational functions involved. This research results in a knowledge-based performance management system design that can be applied to airport companies. This system is expected to help airport companies in improving their performance and achieving organizational goals.

Abstract

High operational costs have had a major impact on Bandung's CV XYZ rubber production plant. Labor, specifically in the completed goods section, accounts for the largest portion of operational expenditures, costing Rp 377,190,000. A labor and process efficiency study is required in order to cut expenses. This study intends to evaluate the labor and process performance of CV XYZ's finished goods division and make recommendations for enhancements. CV XYZ has enough capacity, according to the capacity study, to satisfy current demand without going beyond. Small products are used 65.91% of the time, medium products 67.73%, and large products 53.81%. The efficiency rate for medium-sized products is 81.59%, large-sized products is 64.82%, and small-sized products is 79.41%. Waiting waste was identified as the most common process by a thorough process mapping. Eight workers were found to be under load, whereas one worker had a typical workload, according to the workload study. Reengineering business processes proposes integrating components or operations to better. During the rubber vulcanization process, the suggested method cuts down on worker idle time. The new workload distribution is computed using the re-engineered business process as a base. Even though it falls under the under-load category, this leads to fewer employees and a greater burden. By using this suggested method, CV XYZ can save Rp 125.730.000,00, or 33% of its direct labor expenditures
