Abstract

This research aims to analyze the use of HVS paper ash (Hout vrij schrijfpapier) as a substitute for cement in concrete mixtures. HVS paper is one of the most widely used wastes by humans, generally used in government, private, and school agencies. This research aims to evaluate the slump value, assess the concrete compressive strength value, analyze the impact of using paper ash on concrete compressive strength using the ANOVA (Analysis of Variance) method, and study the type of cracks in each concrete sample based on ASTM C39-18 standards. The variations used were 0%, 10%, 15%, and 20% as cement substitution. The average compressive strength of each sample was 20.2 MPa, 23.3 MPa, 20.4 MPa, and 18.3 MPa, respectively. This increase occurred because paper ash has a higher silica content compared to Portland cement. However, the use of paper ash requires an activator to accelerate the mechanical properties of the paper ash itself. The activator used in this research is NaOH with a level of 4 mol. Thus, the increase in compressive strength produced by paper ash can be used as normal concrete.

Abstract

Lina Store is a business that operates in trading activities which always plans the purchase of goods for product availability in the store. In planning the purchase of goods in the shop, it is still done only with estimates, so it is difficult to determine the purchase of goods for inventory in the shop. To overcome this problem, researchers built an information system using the moving average method to calculate planning for purchasing goods to meet customer demand. The information system built is an information system for planning stock purchases at the Lina store using the PHP programming language with the CodeIgniter framework, MySQL database and run using an offline server, namely XAMPP. The results of this research are that this research has succeeded in designing and building a web-based information system for planning purchases of goods at Lina stores to overcome problems and improve the planning process for purchasing goods at Lina stores and applying the moving average method with a calculation period of 3 months. This system will be able to help Lina's shop determine the number of purchases of each item in the following month. Keywords : Moving Average, Purchases, Inventory, Information System

Abstract

Transportation is the movement of people or goods from place to place and has two types of land and sea transport. Land transportation includes road transport, such as cars, buses, and motorcycles, as well as trains. One part of land transport is the public transport terminal, the railway station. The railway station serves as a stop or transit point for passengers built to meet the needs of passengers. According to the Directorate General of Railways, existing railway stations in Indonesia can be categorized by class and function. Cimahi Station is a type C station located in Baros Village, Central Cimahi District, Cimahi City, West Java. There are several factors that can affect the performance of stations that provide good facilities and services. The influencing factors are convenience, safety, accessibility, and ease of the station. Thus, in this study, it will discuss passenger circulation patterns, vehicle circulation patterns, parking area conditions, and parking performance at Cimahi Station. The research methodology used is observation and questioning of Cimahi Station users. The result was found that the passenger circulation pattern was a linear pattern, while for the vehicle circulation pattern there was one entrance and exit at the station. The layout of passenger and vehicle circulation patterns is described using AutoCAD. The condition of the parking area at Cimahi Station is used only for two- and four-wheeled vehicles, but the parking capacity of car users is less than that of motorcycle users. And also in the parking performance of Cimahi Station has different perceptions from car and motorbike users. In terms of convenience, convenience, safety, and accessibility factors for motorbike users, the value is higher than that of car users.

Abstract

Kiaracondong Station is the second largest station in Bandung that serves intercity travel routes and commuter trains. Referring to The Regulation of The Minister of Transportation Number 48 of 2015 concerning The Minimum Service Standard for Transportation of Persons by Train, one of the indicators for measuring the level of satisfaction of train passengers towards station performance is by providing vehicle parking facilities. This research aims to analyse and evaluate parking performance based on user perceptions. The research uses primary data from direct observation results and the dissemination of questionnaires as well as secondary data, namely the Technical Guidelines for Implementation Parking Facilities by the General Director of Land Transportation. The data analysis technique used is a descriptive statistical analysis technique. The analysis results show that there are no available pedestrian path facilities and there is a point of circulation conflict between the outgoing motor vehicle and the inflow of the car vehicle. The number of existing parking slots for car vehicles with a size of 2.5 x 5 m is 114 slots and 273 slots for motorcycle vehicles with a size of 1 x 1.35 m. The number of visitors’s vehicles only filled 39-44% of the SRP slots that are available, so the parking facilities that are provided can still accommodate parking needs for visitors/passengers. Some things that need to be improved in parking facilities from the perception of passengers/visitors are the aspect of convenience, availability of parking space, comfort and security.

Abstract

Vendor selection is a strategic aspect that directly influences the success of operational activities in construction projects, especially in the procurement of primary materials such as cement. This study aims to provide an objective recommendation in determining the best cement vendor for CV YPP using the Analytical Hierarchy Process (AHP) method. Four main criteria analyzed include price, product quality, distribution distance, and compliance with contract specifications. Data were collected through questionnaires from project managers, procurement teams, and logistics personnel, then analyzed using the Super Decisions software. The results show that product quality holds the highest weight in the decision-making process. Vendor A achieved the highest global priority score (0.512), indicating it as the most optimal alternative for cement procurement. This study confirms that the AHP method can provide a systematic and measurable framework to support effective and efficient vendor selection decisions.

Abstract

FDX company engaged in the distribution of two-wheeled vehicle spare parts. Two-wheeled vehicle spare parts are components or elements specifically designed and manufactured to replace original parts of two-wheeled vehicles that are damaged, worn out, or no longer functioning optimally. These spare parts include various mechanical, electrical, and structural elements necessary to ensure vehicle performance, safety, and operational continuity in accordance with factory standards and applicable safety regulations. Based on existing data, there has been a noticeable increase in the demand for spare part deliveries in the city of Bandung. Consequently, the company requires an optimal route planning strategy to ensure that the products are delivered within the specified time frame and at minimal cost. This research aims to determine the shortest delivery route for distributing two-wheeled vehicle spare parts to optimize both travel distance and transportation costs. The algorithm is used to construct a graph that identifies the shortest path by evaluating all possible routes from the origin to the destination. Future studies may apply Dijkstra’s algorithm or the Gabow algorithm to compare and potentially obtain more optimal results.

Abstract

Motorcycle maintenance and service activities require an effective and safe component cleaning process, both for the operator and the environment. The use of gasoline as a cleaning fluid has many disadvantages, including not being environmentally friendly, flammable, and potentially damaging rubber components. This research designs and builds a tool in the form of a motorcycle part cleaning tub with a closed circulation and filtration system, which uses engine degreaser liquid as an alternative cleaning fluid. The design process includes analyzing technical requirements, selecting materials such as stainless steel for the frame, and applying TIG (Tungsten Inert Gas) welding techniques to ensure the strength and durability of the tool. The filtration system allows the liquid to be used repeatedly, thus increasing efficiency and reducing hazardous material waste. Test results show that this tool is able to improve mechanic work comfort, keep the work area clean, and provide more optimal cleaning results. With its ergonomic and environmentally friendly system, it contributes to increased workshop productivity and supports sustainable work practices. This study shows that simple innovations in technical aids can have a significant impact on operational efficiency and safety aspects. Keywords: Cleaning tub, engine degreaser, filtration system.

Abstract

Construction projects are one of the most complex sectors, requiring structured planning and execution. Effective implementation of supply chain management (SCM) is essential to achieve time efficiency and avoid delays. This research aims to analyse the application of Supply Chain Management (SCM) to the time performance of structural works using the Supply Chain Operation Reference (SCOR) method. The research method used Plan, Source, Make, and Deliver indicators with data collection through questionnaires and interviews. The results showed that the four SCM processes simultaneously had a significant effect on time performance, with the Deliver variable having the greatest influence. However, partially, each variable has not shown a significant influence. The resulting level of determination indicates that SCM variables can explain 42.9% of variations in time performance, while the rest is influenced by other factors outside this study. Keywords: Supply Chain Management, Time Performance, SCOR, Construction Project, Efficiency.
