Abstract

A systematic literature review is a rigorous method of assessing and combining research results compared to the usual literature review, which consists of annotated bibliographies, a systematic review of the existing literature regarding specific research questions on a topic of interest. Statistical Process Control (SPC) is a well-established technique in a context that has recently been used in software production. Software production is not like manufacturing because it requires more human resources and machines, resulting in an item's one-time production. It is therefore essential to assess what SPC works in a software context. Thus, this consideration has motivated us to define and conduct an evaluation review to assess whether SPC is used effectively and genuinely Quality Control Cycle (QCC) in Indonesia's various industries. According to a systematic literature review process, an established protocol was revised and refined by the authors. This journal collection of journals has been used in various industries in Indonesia. We report our preliminary considerations and results in a systematic review on the SPC and find 30 journals collected as references for readers in making research journals related to SPC. Our products and first impressions are favorable. This journal collection can also make it easier for researchers to get the desired journal references.

Abstract

Production planning and control in a manufacturing company involves all production activities from raw material requirements to finished products. The Jakarta Automotive Components Industry is engaged in manufacturing which produces leaf spring products that are sent to several regular customers, namely the Automotive Assembly Industry. Leaf spring Hino OW 190/200 is the type of spring ordered and shipped to PT. HMMI. Based on data for the January-December 2019 period, the demand for Hino OW 190/200 leaf spring has fluctuated quite significantly. The purpose of this study was to plan and control the production process of Leaf Spring Hino OW 190/200. Forecasting for the next 12 periods is based on demand plots from the previous 12 periods, calculating the Aggregate production plan, determining the Master Production Schedule (MPS), calculating raw material requirements using the Hybrid and Lot for Lot methods. The results showed that to support the smooth production, it can be seen that the production planning for forecasting calculations using the Linear Regression method generates a model Y=319,575+3,723X. Calculation of the need for main raw materials and components in 2020 uses the Hybrid and Lot for Lot method, which is 256,182.88 kg, much smaller than the company's calculations based on 2019 data, namely 259,827.40 kg.

Abstract

Islamic banking has enormous potential considering that Indonesia has the largest Muslim population in the world. The current performance measurement system for Islamic banks is still financial and non-financial, and there is an imbalance in the actual value of the company because it views financial and non-financial measurements as two important things that are not correlated. A comprehensive performance measurement system is urgently needed considering that Islamic banks must be able to follow market developments, such as the Balanced Scorecard. The aim of this research is to analyze the influence of the financial, customer, internal business, learning, and growth perspectives. Analyze which perspective is the most dominant in influencing the management performance of Islamic Banks. The results of the current research are Islamic banks in the growth stage towards the sustainability stage because they are supported by the application of goal-setting theory. Increasing employee performance satisfaction can be achieved by implementing an optimal system of leadership, motivation, and work spirit. This can be shown by the success of Islamic Banks in getting several awards from the business media.

Abstract

Every village has Village Superior Products (Prudes) which have economic value that can advance the economy of rural communities. However, the consolidation of the Prudes results is still not optimal, it can be seen from the poverty rate in rural areas which is still high when compared to the level of poverty in the city. To overcome this, it requires the efficiency and effectiveness of distribution centers in rural supply chain systems in order to consolidate the Prudes products from a number of villages to a number of customers/consumers. However, the main problem is how many distribution centers are needed and where are the distribution centers located in an area that has the same type of Prudes. Therefore, the aim of this research is to find the best location P from a number of candidates distribution centers (N = 59 villages) where P ≤ N. To achieve the objectives of this study, the P-Median method is used with the help of AMPL software as a data processing tool. in order to complete the model of the P-Median. The objective function of the P-Median model is to find the minimum value of the total cost based on distance (), production volume (), shipping costs (), and fixed cost () at a number of DC facilities. In the process before the completion of the P-Median model, the approach is first carried out proximity analysis which consists of the pre-qualification and qualification processes in determining candidate facility candidates distribution center. This approach was taken to cover the limitations of APML software in processing data. The result of this research is that the optimal number of DC facilities in five DC facilities with a total cost minimum of IDR 91.80 billion. Meanwhile, the facilities are distribution center located in the village of Sanuanggamo, North Tongauna District (P11), Awuliti Village, Lambuya District (P17), Mumundowu Village, Pondidaha District (P36), Duriasi Village, Wonggeduku District (P44), and Puday Village, West Wonggeduku District (P53).

Abstract

One of the obstacles facing micro, small and medium-sized enterprises (MSMEs) in Indonesia is the bullwhip effect. The bullwhip effect is an event that occurs in the supply chain due to an increase in order fluctuations or order cancellations due to information distortions. This study aims to determine the value of the bullwhip effect and explain the main causes of its occurrence in order to explain about the approach to reducing the bullwhip effect in micro, small and medium-sized enterprises (MSMEs) in Indonesia that operational management can be maximized through operational management. This study uses quantitative methods to determine the value of the bullwhip effect. And qualitative methods are used to identify the root cause and reduction of the bullwhip effect. With primary data from interviews. In addition, secondary data comes from demand data and order data on products for distributors and retailers managed by the company. The results showed that the value of the bullwhip effect on the product at one of the micro, small and medium-sized enterprises (MSMEs) in Indonesia was almost completely above 1.00 and above the specified parameters. This provides information that there is a product bullwhip effect in one of the micro, small and medium-sized enterprises (MSMEs) in Indonesia. Meanwhile, the main cause of the bullwhip effect in one of the smallest, small and medium-sized enterprises (MSMEs) in Indonesia is a demand forecast error.

Abstract

Currently, the industrial era 4.0 coincides with the covid 19 virus which is an opportunity and a challenge to choose the right business strategy. Based on the results of the evaluation of previous studies and the analysis in this study, it is known that currently there are no sensors installed on the tools used for material transfer, communication between machines and machines (M2M) currently there is no data generated so no data is communicated, the interface between humans and machines (HMI) currently uses a local user interface through the Pro-St application and the interface on the fanuc machine, the current transportation system is moving materials to production machines, a manual transportation system, namely hand lifts, materials that have been packaged and will be stored in the warehouse using a forklift (machine for manual transportation), while the unit product movement from the fanuc machine already uses a conveyor, the transportation unit as an information carrier currently has a mechanism for individual identification of materials but the status of the material is not identified in the IT system, the current storage system for placing materials is still done intuitively and the identification process for storage locations is still listed manually on the blackboard. In order for the intralogistics system to implement intelligent supply chain and logistics based on industry 4.0, it is proposed to install sensors on the device to identify material movement and the sensor and actuator interaction data can be analyzed, network connections between devices for M2M communication, use of mobile user interfaces to monitor intralogistics processes and status. identified material in the IT system.
