Forecasting Car Demand in Indonesia with Moving Average Method
Fuad Dwi HanggaraShow Abstract | Download PDF | DOI: 10.31004/jestm.v1i1.5 | Check in Google Scholar
The automotive industry is an industry that requires a long process and high manufacturing costs. improper can have fatal consequences if not planned properly will cause financial losses. Production planning using statistical tools such as statistical process control can control the right amount of production according to customer demand. Part of the statistics that makes planning for future production planned is forecasting. Precise production quantities require the specialized abilities of technicians experienced in forecasting. The approach used in forecasting uses a quantitative approach using production data, and sales data of the Gabungan Industri Kendaraan Bermotor Indonesia 2020. The use of the Moving Average method in forecasting will determine the number of production limits so that excess production can be avoided, and the automotive industry in Indonesian has many opportunities to develop its production.

Improving the quality of green space and efforts to improve the function of the area in the academic environment must be considered as an integral part of building arrangement activities. This is because the aspects of the building and the environment are inseparable components of settlements, supporting each other in a balanced, harmonious, and harmonious manner. As a campus that applies the concept of “Green Campus”, of course, it wants the quality of its environment to be well maintained even though it has the development of facilities and infrastructure, Universitas Pahlawan must of course also fulfill these provisions. Therefore, it is very necessary to model in planning the Park Green Open Space Planning Model at the Hero University with various considerations that are adapted to regional conditions, land area and benefits that can be enjoyed optimally by the academic community. Environmental Park planning model is carried out by reviewing based on spatial (spatial) and social aspects. The importance of the Environmental Park planning model is due to not applying an appropriate planning model so that direct utilization is not maximally felt by the academic community. This study examines more deeply the relationship between the spatial and social aspects of the environmental park

Riau Crumb Rubber Factory (PT. RICRY) is a manufacturing company engaged in processing raw rubber into semi-finished goods. The raw materials used are Ojol and Lump which come from rubber farmers in the Riau area themselves. The products produced consist of two types based on their quality, namely SIR 10 and SIR 20 which will be reprocessed as raw materials for making tires. This product will be exported to various countries such as America, Singapore, South Korea, Australia, Japan, China and so on. This company has a production target of 20,000 tons/year. Based on data in 2014, the company's production only reached 88.33%, which was 17,666.775 tons/year. One of the causes of not achieving the production target was due to problems at the milling station, namely the Mangel/Crepper machine. The large number of raw materials that will go through the milling process causes the Mangel/Crepper machine to operate beyond its capacity. This production process takes place over a long period of time, causing damage to the main engine components such as Bearings, roll grinders, and Dynamo, resulting in Downtime in the production process. Several factors cause problems in the Mangel/Crepper machine, namely human factors, machines, methods, and raw materials. Therefore, the calculation of efficiency on the Mangel/Crepper machine was carried out using the Overall Equipment Effectiveness (OEE) method. It aims to increase production yields. Based on the calculation results, the average Availability Ratio value is 96.512%, the Performance Efficiency Ratio value is 94.835%, the Rate of Quality Product value is 100% and the OEE value of the Mangel/Crepper machine is 91.528%. These values generally meet international standards for each variable. However, the Performance Efficiency Ratio value still does not meet the existing international standards, so it is necessary to make improvements so that the Performance Efficiency Ratio of the Mangel/Crepper machine can reach the international standard values that have been set.

Analysis of Web-Based Geographic Information System Mapping of Broken Roads in Kampar Regency
Dilla Fafira, Novi Yona Sidratul Munti, Beni SetiawanShow Abstract | Download PDF | DOI: 10.31004/jestm.v1i1.11 | Check in Google Scholar
Road is a very vital land transportation infrastructure and transportation route. Apart from being transportation, roads also function as a medium of socialization and accessibility for the community. Damage to the road is a big problem for some people who use the road every day. Therefore, a public complaint system is needed to the authorities in reporting the location of damaged roads, so that road repairs can be carried out quickly. The purpose of this study is to make it easier for the public to report damaged road conditions using a damaged road reporting system website that can be accessed online. The research method used in this study is the waterfall method. This waterfall method has a sequential flow of software starting from planning, analysis, design, implementation, testing and maintenance. The design of this system uses Unified Modeling Language (UML) and Object Oriented Analysis Design (OOAD). The programming language used is PHP Framework Yii and MySQL database. This research was conducted on a website reporting damaged roads in Kampar Regency which also provides information on roads that have been repaired in Kampar Regency and provides information related to the Kampar PUPR Service. With this system, PUPR's performance in repairing damaged roads that have been reported by the general public will be better.

Web-Based Programming of Geographic Information System Programming Of Broken Road Mapping In Kampar Regency
Muhammad Rifandi, Beny Setiawan, Novi Yona Sidratul MuntiShow Abstract | Download PDF | DOI: 10.31004/jestm.v1i1.13 | Check in Google Scholar
In Kampar Regency, congestion occurs at many points, both on protocol roads and village roads. In addition to the fact that Kampar Regency has a large population, the density of transportation or congestion that occurs is also caused by damage to roads. This is also a factor that causes traffic accidents on the highway. The damage to the road could not be handled quickly by the Kampar government. This is because Kampar Regency has a fairly large area, and the survey process that must be carried out is quite time-consuming and costly. Difficulties are also experienced by the community who wants to report a road damage, including because they do not know the procedure that must be done to report it. The Road Reporting System, offers a reporting mechanism, where the reporter can send his report anywhere in Kampar Regency to the Department of Highways of Kampar Regency. The purpose of this research is to make it easier for the public to report damaged road conditions using a damaged road reporting system website that can be accessed online. . The research method used in this research is the waterfall method. This waterfall method has a sequential flow of software starting from planning, analysis, design, implementation, testing, and maintenance.

Road is a land transportation infrastructure and transportation route that is very vital at this time. Damage to the road is a big problem for some people who use the road every day. Kampar Regency during 2020 damaged roads including high, lightly damaged asphalt surface conditions 59.20 km, gravel heavily damaged along 4.00 km, and heavily damaged dirt road surface conditions along 2.80 km. Damage to roads in Kampar Regency can cause various kinds of losses, such as obstruction of road access to the destination, accidents, and damage to vehicles due to passing through bumpy and potholed roads, thereby increasing vehicle repair operational costs. Damage to roads can be overcome by making plans in a web of public complaints to the authorities in reporting the location of damaged roads. The purpose of this research is to help make it easier for the public when reporting damaged roads to PUPR by using the online damaged road reporting system by entering their name and email. The research method used in this research is the waterfall method. This waterfall method has a sequential flow of software starting from planning. The design of this system uses the Unified Modeling Language (UML) and Object-Oriented Analysis Design (OOAD).
