INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) <p>The first edition of International Journal Engineering and Applied Technology (IJEAT) has been published at the Nusa Putra Univesity, Sukabumi, Indonesia. The first paper was published in March 2018 with a frequency of two issues per year (May and November).</p> Nusa Putra University en-US INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) 2620-9632 APPLICATION OF K-MEANS ALGORITHM ON FAVORITE MENU SELECTION AT WARUNG NASI ALAM SUNDA <p>Warung Nasi Alam Sunda is a stall that does sundanese culinary business that serves several dishes of various vegetables, soto, chicken, fish, and others. In the application of favorite menu, Warung Nasi Alam Sunda determines it randomly, so it does not match the report given. This research aims to assist the restaurant in determining the favorite menu. This research uses data mining techniques with K- Means. Input attributes in this study include price, taste, favorites. In this study, it can be produced that the results of grouping into 3 groups namely c- 1=fried chicken, c-2=fried carp and c-3=soto betawi. After 9 iterations, the 8th and 9th results are the same as c-1=9, c-2=22 and c-3=16. Then get the highest result as follows fried chicken=53, oxtail soup=49 and intestinal satay=42. Judging from the largest to smallest order of the sample 47 variables taken only 3 representatives. So the highest result is fried chicken. That will be the favorite menu at Warung Nasi Alam Sunda. System design using UML, system implementation using PHP and MySQL. The goal that this study wanted to achieve was to be able to cluster your favorite food menus using the K-Means algorithm</p> Lisnawati Fitriyani Neneng Komariah Yusef Bintang Fajar Sudin Saepudin Muhamad Muslih Copyright (c) 2022 INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) 2022-05-29 2022-05-29 5 1 1 16 10.52005/ijeat.v5i1.55 Automatic VLP’S Recognition For Smart Parking System <p>The system is designed as the authorized automatic vehicle identifier with respect to vehicle owner identification, for the security of the highly restricted areas like housing areas, defence military areas, parliament areas etc. Both of the number plate recognition and the vehicle owner recognition use the image identification technology. The image of the vehicle plate number and the vehicle owner are captured by using a camera and processed with MATLAB. The system contains an embedded section which controls the opening of the security gate and the communication purpose. The user interface provided at the entry/exit gate gives visual assistance to the driver, whether he/she is not permitted at this area or permitted. The entry of the unauthorized vehicle is restricted and the message is sent to the actual vehicle owner which is preregistered in the systems‟ database. The technology adopted in this research can be utilized not only for the security but also in other fields such as parking fee collection, automatic speed control, tracking stolen cars, automatic toll management and access control to limited areas, etc.</p> Iqbal Munawar Anisa Rizky Pajar Rusman Copyright (c) 2022 INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) 2022-05-29 2022-05-29 5 1 17 29 10.52005/ijeat.v5i1.56 EVALUATION LIFETIME SERVICE AND CAPACITY OF THE KADUMALIK DAM RESERVOIR <p>The dam is a construction of water structures built across the river. The function of the dam is to hold and store water, both rain water, river water and water from the lake which will then form a reservoir. Kadumalik Dam is one of the projects of the Directorate General of Water Resources (SDA) of the Ministry of Public Works and Public Housing (PUPR) which will be built in 2020 on an area of 500 Ha. The purpose of building Kadumalik Dam is to meet the irrigation needs of the Irrigation Area (D.I) and meet diverse water needs, but the dam can also pose a great risk as well, namely the risk of accumulation of sedimentation. Sedimentation is one of the factors that is very influential in dam management. A large sedimentation rate will speed up the service life of the reservoir so that the planned reservoir function can be disrupted. Therefore this research is important to know how much the dam capacity and how old the dam service. This study uses analytical calculation methods for sediment transport based on observations and calculation methods with efforts to handle sedimentation. Based on the results of the analysis, the sedimentation rate in the Kadumalik Reservoir is 2.71 tons / ha / year and is classified as an erosion hazard class I or very light erosion rate, calculation of the method with sedimentation handling measures results in the analysis of the Sediment Control Building (BPS) can control 2.2 million m3 of sediment, so that it can extend the reservoir service life to 50 years.</p> Utamy Sukmayu Saputri Yuli Suharnoto Asep Sapei Niels vuegen Copyright (c) 2022 INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) 2022-05-29 2022-05-29 5 1 30 37 10.52005/ijeat.v5i1.57 Modeling Low Income Vehicle Ownership in Cibadak District <p>The number and growth of vehicles is a separate problem related to the problem of sustainable transportation. In 2019, the number of motorized vehicles in Indonesia was recorded at more than 448 vehicles per 1,000 people. And specifically for motorcycles, it reaches 365 vehicles per 1,000 people. The growth of motor vehicles is significantly influenced by economic growth as measured by Gross Regional Domestic Product. When compared with the growth of motorized vehicles, it can be concluded temporarily that the high growth rate of motorized vehicles at the end of this decade has an impact on traffic problems on the highway. To see the trend between economic growth represented by regional gross domestic product and motorcycle growth, a model is needed to be useful for policymakers who handle the road in making decisions. The results showed that the growth model of motorcycles in Sukabumi can be approached with a linear regression equation. With the sample from the Cibadak sub-district, the area is classified as a low-income area.</p> Hendri Mulyana Utamy Sukmayu Saputri Ardin Rozadi Lugovaya Nika Vyaceslavovna Copyright (c) 2022 INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) 2022-05-29 2022-05-29 5 1 38 46 10.52005/ijeat.v5i1.58 The estimated cost of work and K3 construction of retaining walls <p>One of the methods used to control the stability of the soil so as not to experience a landslide is to build a retaining wall. In carrying out the work, of course, it is necessary to pay attention to occupational safety and health for all those involved in a project, including the community around the project, therefore, it is important to calculate costs before starting work, so that the project can be carried out properly according to regulations, objectives, functions, benefits, impacts, costs, quality, time, and K3 or occupational safety and health. This study aims to determine the cost of retaining a cliff wall using the main material of mountain stone/split stone, including labor costs, materials, tools, and occupational safety and health (K3) costs. This research uses quantitative descriptive method. To complete this research, we need data on the budget plan for the construction project for the construction of retaining walls, and factual costs at the project site. The data sources consist of project documents, contract documents, and direct observations on site. This research has identified the cost of materials, tools, labor, and K3 in units converted to cost/m<sup>3</sup>, and produced a coefficient of unit price analysis for retaining wall work. The results of this study can contribute to estimating the cost of retaining wall work using mountain/split stone specifications at an early stage during planning, using unit costs/m3 of work, both by planners, contractors and the general public.</p> Richa Rahmalia Sunhadji Heru Salasa Ismail Imanulhaq Paikun Novohatko Elena Nivolaevna Copyright (c) 2022 INTERNATIONAL JOURNAL ENGINEERING AND APPLIED TECHNOLOGY (IJEAT) 2022-05-29 2022-05-29 5 1 47 56 10.52005/ijeat.v5i1.59
