In January 2022, there were 8 reports of missing persons, and this number doubled to 16 in March 2022. Currently, the police rely on reports from the public to find missing individuals. They then conduct direct checks in the field, confirm the reported characteristics, and contact the families. However, this method is not considered modern or efficient enough to handle the increasing number of missing persons cases. In this modern age, technological developments, especially in mobile applications, can offer more effective and efficient solutions. Therefore, a prototype application for missing persons based on Android was developed as an alternative to help address the issue of missing persons, especially in Jayapura City. The missing persons application underwent black box testing to ensure that its functions and inputs are working correctly, and the validation function was used to check its accuracy.

V. Tethool <p>Manokwari is a District located at the junction of three main plates forming the earth's crust, namely the pacific plate. This makes Manokwari Regency prone to earthquakes. Therefore, building planning must be designed with the concept of earthquake-resistant buildings. Steel material is one type of material that is often used for planning earthquake-resistant building structures because it has high strength and lightweight properties that it is good for earthquake-resistant buildings. One of the methods often used in the planning of earthquake-resistant steel structures is the special moment resisting frame system (SMRF). This structural system is used because it has full ductility that it can survive in areas with a high earthquake risk. This planning modification was carried out at the DPW NasDem Office building by changing the main structure in the form of reinforced concrete using a steel structure with a special moment resisting frame system (SMRF). Based on the calculation and analysis, the results were obtained, namely: the dimensions of the secondary beam are IWF 300x150x6.5x9, the main beam 1 IWF 350x250x9x14, the main beam 2 IWF 300x200x9x14, the column dimensions KC 450x200x9x14 (floors 1-3), KC 400x200x8x13 (floors 4-5), and KC 350x175x7x11 (elevator columns). Floor slabs are 12 cm thick and 10 cm thick for roofing plates. The SRMF joint design uses a high-quality bolt (A325) with the quality of the BJ41 joint plate and the planning results meet the requirements.</p> 2023-06-21T00:00:00+00:00 Copyright (c) 2023 Putri Aru Anjani, Radinal Bakri, Yoga C.

F. Puteri Lion F. Marini <p>The number of work accidents in the construction sector in the world is generally higher than the number of accidents in other sectors such as the manufacturing and industrial sectors due to the lack of K3 construction experts as well as the low awareness of workers in the field. Therefore, the K3 program is implemented to prevent work accidents. The purpose of this research is to be able to identify a hazard, analyze work risks, and determine controls using the HIRADC method on the lower structure of the South Manokwari Regional House of Representatives building. This study used a qualitative analysis method by carrying out and making observations in the field, distributing questionnaires to 8 informants, and interviewing the main informants, namely K3 experts. Based on the results of an analysis of the lower structure of the South Manokwari Regency Regional House of Representatives building, 141 accident risks were identified for each job with a percentage of the risk level before control was carried out, namely extreme risk (E) of 16,31%, high risk (H) of 35,46%, moderate risk (M) of 45,39%, and Low risk (L) of 2,84%. These results are still very high, so it is necessary to carry out a control. After controlling, the risk level decreased drastically, and at safe limits, the results were: extreme risk (E) of 0,00%, high risk (H) of 0,00%, moderate risk (M) of 19,15%, and Low risk (L) of 80,85%.</p> 2023-06-21T00:00:00+00:00 Copyright (c) 2023 Aprisillia K.

One of the causes of declining electricity quality is the shrinkage that occurs in the electric power network, network losses cannot be avoided but can be minimized by shortening the network, performing maintenance and maneuvering the load. Energy losses in the electrical system come from the power generation, transmission and distribution system. In the transmission system, energy losses can be minimized by increasing the transmission voltage to high and extra high voltage levels. The load curve is a curve in a time range which shows the value of electrical energy use and load for a feeder so that PT. PLN (Persero) UP3 Manokwari can estimate power requirements. Expense curves can be divided into three types, namely daily curves, monthly curves and annual curves. Research throughout October 2021 used quantitative methods in processing data and calculating losses so that the power loss was 2.0070% and the energy loss was 1.9847%. This loss is still far below the state electricity company standard D3.002-2 (2008) in range of 5% to 10%.</p> 2023-06-21T00:00:00+00:00 Copyright (c) 2023 Herybertus Rivanaldi Podajow, Adelhard Beni Rehiara, Jamius Bin Stepanus
