Yorigo Coffee shop Business Feasibility Study Analysis, Bandung

Ira Rachmawati Arsyady — 2024-04-15

The purpose of this research is to analyze whether Yorigo Kohi coffee shop can develop as expected by the owner, where this coffee shop is located in a residential area where there are no coffeeshops, there are rarely sellers, there are few offices. The menu sold by Yorigo Kohi Coffee shop tends to be like a coffee shop with cheap prices but with a contemporary touch, so that this coffee shop is quite busy being visited by young people who have just returned from school or college and workers who are just going to do assignments or have meetings.

This research uses qualitative methods, where the data used comes from management, using literature studies, collecting information through several journals and sites on social media.

The findings from this research are that, even though it has only been running for a few months, Yorigo Kohi Coffeeshop is quite promising to be developed

The results of this research can also help develop theories about Micro, Small and Medium Enterprises (MSMEs) and entrepreneurship, especially for the coffee business, so that researchers can develop a framework for understanding small businesses. With practical implications, it can improve coffee shop businesses in identifying business opportunities, understanding customers, improving product and service quality, and can also help coffee shop owners in designing more effective marketing strategies.

DESIGN AND CONSTRUCTION OF A HYDROPELECTRIC POWER PLANT PROTOTYPE FOR LEARNING MEDIA IN THE LABORATORY

Tia Setiawan — 2024-04-15

This research produces a hydropower plant prototype, understanding the function and working performance of the hydroelectric power plant prototype, this research aims to provide an overview of hydroelectric power plants. This research went through four stages, first data collection, second design, third manufacturing, fourth testing. And the manufacture includes making a frame for placing prototype components for a hydroelectric power plant, making blades to convert water energy into electrical energy. The results of the research concluded that the hydroelectric power plant prototype functioned well by producing electric current from a generator of 60 Volts with a water flow of 0.357 m3/s which could turn on 12 Volt DC lights.

APPLICATION OF BIG DATA CONCEPTS TO OPTIMIZE ASSET MANAGEMENT AT PT POS INDONESIA

Muhammad Ruslan Maulani — 2024-04-15

This research aims to apply the Big Data concept in order to optimize asset management at PT Pos Indonesia. PT Pos Indonesia needs to adopt Big Data technology to collect, manage, and analyze data generated by various sources. The research method used in this study is Scrum, a software development framework that focuses on flexibility and team collaboration. This research involves several stages. First, a needs analysis and identification of assets that need to be optimized were conducted. Next, data was collected from various sources such as asset management systems. The collected data is then processed and stored in a suitable Big Data infrastructure. Next, using the Scrum method, the research team and stakeholders were involved in the process of developing a Big Data solution. Short sprints were conducted to implement and test various components of the system, such as the data collection platform, analysis algorithms, and visualization of results. Regular iterations allowed for continuous adjustments and improvements according to feedback provided by the team and stakeholders. The result of this research is a prototype application and the application of the Big Data concept implemented in the asset management application at PT Pos Indonesia. By optimizing the use of data, PT Pos Indonesia can increase operational efficiency, improve decision making based on more accurate data analysis.

DESIGN OF A PORTABLE SPOT WELDING MACHINE FOR LABORATORY SCALE

Irna Sari Maulani — 2024-04-15

Specifically used to connect plates. A high electric current is applied to the material that is squeezed through the electrodes during the pressing process by the two electrodes. Spot Welding is widely used in the industrial world both large and small scale. In large industries, spot welding has a solid and fixed design, meaning that the method of placement has been determined in a special place and if you want to move it, you have to use heavy equipment. Whereas for small-scale spot welding it is urgently needed for thin plate processing, but the price and shape which are difficult to move certainly require innovation so that the needs of small industries can be fulfilled. In the manufacturing process course in the Mechanical Engineering Study Program, Faculty of Engineering, Galuh University, there is welding material and practice, of course, to achieve maximum learningoutcomes in welding practice, it is necessary to make a portable spot welding equipment. From the discussion above, the authors are interested and

inspired to design a portable spot weld machine for the laboratory scale, starting with drawing, planning, sketching or assembling several separate elements into a single unit that is used to describe tools using solidwork applications and the Finite Element Method (FEM) or commonly called Finite Element Analysis (FEA) as an analysis tool.

The method used in the design process for portable spot welding machines is made using Solidwork software. The design dimensions of the spot welding machine are 63 cm long, 14 cm wide, 14 cm high. The dimensions of the pedal that has been made are 10 cm long, 38 cm wide and 98 cm high. Electrical specifications require 700-800 watts of power, 220 volts, 5 amperes electric current.

The design analysis that has been carried out is divided into stress analysis which has a value of 2,476,233N/m2, while the yield stress of the ASTM A36 material is 250 MPa so that the frame is declared safe. Displacement and strain analysis produces a value of 0 and safety of factor analysis produces a value of 101.

QUALITY CONTROL ANALYSIS USING METHODS FAILURE MODE AND EFFECT ANALYSIS (FMEA) IN GRILLE PRODUCT Air Inlet

Lia Milana — 2024-04-15

PT Solo Plastik Indonesia is a company that produces plastic motor vehicle components. The standard set by the government regarding defective products is zero defect. From the data obtained in 2023 at PT Solo Plastik Indonesia, it shows that the percentage of defective products that occurred reached 33% so that the target was not met. To solve the problem, the Failure Mode and Effects Analysis (FMEA) method is used to identify potential failures in the product, consider the risk of failure, and identify the risk of failure, as well as identify and implement corrective actions to address the most important problems. Based on the results of the study, the highest defect was obtained, namely silver defect of 76%. The causes of defects are caused by human factors, machines, materials, and methods. Based on the research results, the highest RPN value on silver defects is 140 points with the cause of silver defects from material factors, namely contamination from other materials. Controlling the cause of the silver defect problem is by paying more attention to the cleanliness of the machine mold and paying more attention to the inspection of the material to be used. It is expected that by tightening the inspection of materials before use, it can have a significant impact on product quality as expected to avoid defects.

UTILIZING THE SARIMA MODEL AND SUPPORT VECTOR REGRESSION TO FORECAST MONTHLY RAINFALL IN BANDUNG CITY

Astri Nur Innayah — 2024-04-15

As one of the largest cities in Indonesia, Bandung has varying monthly rainfall intensity. High rainfall is very dangerous for people's lives and will have an impact on various sectors such as agriculture, fisheries, tourism, and transportation. For this reason, rainfall prediction is needed as an effort for the government to make policies and the community can anticipate the possibility of high rainfall that occurs. This study compares the effectiveness of SARIMA and Support Vector Regression (SVR) models in predicting monthly rainfall objectively, with the aim of improving decision making for stakeholders. Forecasting rainfall data is carried out based on the best method of the two methods that have been compared. The results showed that the SARIMA method outperformed the SVR method in forecasting precision, as seen from the lower RMSE value of 93.2045. The results provide valuable insights into weather prediction methodologies, benefiting authorities and the public.
