Abstract

After the economic crisis in 1997, the growth of Big and Medium Scale Industries (MBI)have been slowing down. The perspective of business returns to SME’s. Meanwhile, the problemsof rubber SME’s products, some of them, have been known as slow technology innovation, slowoutput growth (productivity) and lack of working capital. To maintain the competition in themarket, rubber SME’s products must accompany some strategies, in order to survive in themarket and having a bargaining position. This paper just made a recommendation of a model tooptimize the growth of rubber SME’s products. The spread and diffusion of MBI as a leader torubber SME’s products as follower can be done by making some assumptions which must be doneby both parties. By doing this, rubber SME’sproducts could enhance their function in the economyand thus, They will have a secure market to support the economy and sustainability of economicgrowth. To increase the parameters of productivity can be implemented in some ways. The growthof investment, return of capital, working hours, and the growth of human resources quality can bemaintain as the engine of growth for rubber SME’s products. To perform this, They could dothrough raised of the saving, lower inflation and real costs through government’s policy.Thedevelopment of industry should not be imposed only through MBI. The participation of rubberSME’s products should be in the perspective of the government. As it has been mentioned above,the sustainability growth of rubber SME’sproducts must be integrated with the growth of MBI.The government should realize that most of Indonesia population works in this sector, thereforethe growth of this sector will be the locomotive engine of people’s economy.

Abstract

Setting the Wellhead product level needs to be done as bbest as possible to avoid leaks when drilling for oil and natural gas which are caused by pressure differences during drilling. PT BDT as one of the companies that makes wellheads always tries to make the products they produce according to consumer desires. Even though PT BDT has tried its best, it has still received complaints from customers, because of leaks that occurred during drilling and had to incur costs for product replacement. The stages in the research process begin with conducting a field study to identify existing problems in the company and then continue with conducting a literature study to identify theories that can be used as solutions to overcome these problems. The method used to prevent weelhead leaks is the Taguchi method which consists of of three stages, namely stages: planning, implementation, and analysis. The influencing factors used are the amount of sand, the amount of paint, the thickness of the sun blasting, and the pressure of the compressor. This stage is carried out to calculate the influence of each factor used on the quality characteristics used, namely nominal is the best. Based on the results of the wellhead pressure test carried out after the experiment, the Signal to Noise Ratio (SNR) can be calculated. The best level results were obtained to prevent wellhead leaks by setting all levels at level 2, namely the amount of sand was 3.3 grams, the amount of paint was 4.5 liters, and the thickness of the sun was (1.5 mm). The amount of quality loss function incurred by the company due to the wellhead leak was IDR 759,900

Abstract

The warehouse has a very important role in the supply chain network to distribute products to consumers. PT XYZ warehouse uses a rack system to store products before they are distributed to the production process. The problem faced is that the placement of products is scattered and irregular depending on the conditions in the field, products that come are placed in empty places which can cause the storage space to become larger so that the warehouse capacity has not been fully utilized with a utilization rate of 105% and causes a decrease in the actual warehouse capacity. It’s necessary to rearrange the placement of products in the storage location to optimize the utilization rate of storage space, with the dedicated storage method.  This method is to solve the problems that occur in the warehouse layout which includes product placement in the warehouse by placing only one type of product in one storage room. In this method, products will be stored in a fixed location so that product storage is more organized. The results of the application of the dedicated storage method obtained a storage space utilization rate of 100%, while in the existing condition it was 105% with a percentage decrease of 5%.

Abstract

Pallet Delivery Design at PT. XYZ is intended to overcome operator working posture problems in the manual process of tying boxes with ropes, so as to reduce complaints of Musculoskeletal Disorders (MSDs) in operators. Analysis of MSDs complaints was carried out by distributing the Nordic Body Map (NBM) questionnaire to three workers with the results that they experienced complaints of calf, back and knee pain. Based on the results of the Nordic Body Map questionnaire, a Rapid Entire Body Assessment (REBA) analysis was carried out, namely to assess the level of risk. In the initial assessment, REBA produced a score of 9 which indicates a high risk with the use of the tool used. To find out the specifications of the tool to be designed, it is done by measuring the operator's anthropometric data, followed by product design using the Need, Idea, Decision, and Action (NIDA) method as a design approach and the next stage is simulated in CATIA software to confirm risk reduction. The design simulation shows a decrease in the REBA value from 9 to 2, thereby reducing the risk of MSDs for workers.

Abstract

This study analyses the quality of FR S/C Side RH Bracket products at PT BMI, especially concerning the nut dragging problem, which is often the main defect. This study aims to analyze and improve the nut dragging defect problem in FR S/C Side RH Bracket products, as well as provide an understanding of the effectiveness of the improvement in reducing the number of defective products. The analysis shows that FR S/C Side RH Bracket products with nut dragging problems are the most frequent defects, reaching 632 defective units or about 60% of the total defective products before improvement. The Failure Tree Analysis (FTA) method was used to identify the root cause of the nut dragging problem, which revealed that machine factors were generally the main cause, especially setting the spot welding machine parameters too high. In response, improvements were made by changing the parameters on the SW.03 spot welding machine and adding a cooling water line. The results showed a significant decrease in defective products, totaling 1320 units. After the improvement, only 141 units were defective. This research provides an in-depth understanding of product quality issues at PT BMI. It offers solutions to improve product quality and meet customer expectations in the highly competitive automotive industry.

Abstract

Efficiency in setting PID parameters is important in supporting control system performance, especially in automation applications. This research compares two methods of PID settings, namely manually using keypads and LCDs with an online IoT-based way through the Blynk application. The system is designed to control the speed of a 12V DC motor with the response of an FC-51 infrared sensor. Testing is done through an experimental approach by recording the system response to variations in KP, KI, and KD values. The results show that the IoT-based method provides better control efficiency, high flexibility, and ease of data visualization in real time. Blynk also allows storing historical data in graphical form, although it has limitations, such as a maximum limit of sending 30,000 data per month and a limited number of widgets in the free version. Therefore, for future development, it is recommended to use a standalone dashboard or integration with Node-RED to make the system more flexible, secure, and minimal code. Overall, this research shows that the application of IoT to PID control systems can improve the effectiveness of settings and has the potential to be applied more widely in modern automation systems.
