This study on the design of disaster-safe buildings at MIN 3 in Pacitan Regency uses a quantitative descriptive method. With the design of a disaster-safe school, it is hoped that Pacitan 3 Public Madrasah Ibtidaiyah (MIN) can be even more prepared in dealing with disasters. Meanwhile, for a better understanding of disaster-safe schools, it is necessary to hold disaster simulations every certain period at school</strong></p> diana diana rendrarini Copyright (c) 2023 JURNAL PILAR TEKNOLOGI Jurnal Ilmiah Ilmu Ilmu Teknik https://creativecommons.org/licenses/by/4.0 2023-12-29 2023-12-29 8 2 1 6 10.33319/piltek.v8i2.162 Pengaruh Ekstrak Daun Melinjo Terhadap Laju Korosi Pada Material Baja https://pilar.unmermadiun.ac.id/index.php/pilarteknologi/article/view/165 <p><strong>In the rapid development of industry and construction in the current era, iron is a material that is widely used as a material in construction activities around the world. However, iron has the disadvantage of being very susceptible to corrosion. Corrosion is a decrease in metal quality due to electrochemical reactions with the environment. One of the corrosion prevention measures taken against iron is the addition of corrosion inhibitors to inhibit the corrosion rate. Inhibitors from natural materials are an alternative as an environmentally friendly inhibitor. This study aims to determine the efficiency of using melinjo leaf extract inhibitor in inhibiting corrosion rate in 3% Nacl corrosive media. The method used is the mass loss method to see the value of the corrosion rate. This study uses ST 37 steel plate material with a size of 2x1.5x0.12 cm. The concentration variation of melinjo leaf extract is 0%, 3%, 6%, and 9% with a soaking time of 14 days. The results showed that the addition of melinjo leaf extract as an inhibitor can reduce the corrosion rate with the smallest corrosion rate of 0.0449 mmpy and the greatest inhibitor efficiency is at a concentration of 9% at 51.72%.</strong></p> Sutrisno .

Laju Jaya Tour &amp; Travel provides<br>transportation services that are known to be on time in the departure schedule. The problem faced is the lack of departure<br>schedule information which makes consumers do not know the departure schedule. Even ordering tickets is not efficient<br>because they still use the recording process. To solve this problem, a Travel Reservation web was created to make it easier<br>for customers to order tickets. Data collection was carried out by conducting interviews directly related to the object under<br>study and reviewing the necessary needs. This system was built using the JavaScript programming language and MERN<br>Stack technology, namely the Mysql database, the ExpressJs framework on the backend, ReactJs on the frontend and Node<br>Js. In making this information system using the waterfall method. This system has been tested using blackbox testing to get<br>the expected results and the system is feasible to use. The system is expected to be able to assist in managing travel<br>reservation data where as long as ticket ordering is still done manually. This system has limited features so that it can be<br>developed to make it even better and is expected to have high performance in terms of its software development<br>infrastructure, so it needs regular development.</p> Aprilian Ihza Abin Nizar Copyright (c) 2023 JURNAL PILAR TEKNOLOGI Jurnal Ilmiah Ilmu Ilmu Teknik https://creativecommons.org/licenses/by/4.0 2023-12-29 2023-12-29 8 2 11 18 10.33319/piltek.v8i2.152 APLIKASI PENGELOLAAN SERVIS KOMPUTER DI DEWA KOMPUTER BERBASIS WEB https://pilar.unmermadiun.ac.id/index.php/pilarteknologi/article/view/154 <p><strong><em>Dewa Computer is a computer service shop located in the Ngawi district. In addition to servicing computers, Dewa Computer also provides various needs for computer spare parts. However, at this point in the service operational process, the service has not implemented a technology and system at all. In addition, in the process of storing data and recording it is still conventional to use recorded data, this is often an obstacle and human error often occurs. Furthermore, this causes the development and efficiency of its operations to be slow and less than optimal. To be able to change and maximize the potential that exists, in this study a service data management information system was created. This information system is made web-based using the Waterfall method, while for testing the feasibility of the system using the Blackbox testing method. This system is expected to assist owners in service business operations and make it easier for owners and technicians to manage service data to make it more efficient and effective.</em></strong></p> adi samsara adi samsara Copyright (c) 2023 JURNAL PILAR TEKNOLOGI Jurnal Ilmiah Ilmu Ilmu Teknik https://creativecommons.org/licenses/by/4.0 2023-12-29 2023-12-29 8 2 19 27 10.33319/piltek.v8i2.154 R RANCANG BANGUN SISTEM INFORMASI PEMESANAN PAKET TOUR AND TRAVEL BERBASIS WEB (STUDI KASUS GANGSAR WISATA TOUR AND TRAVEL) https://pilar.unmermadiun.ac.id/index.php/pilarteknologi/article/view/148 <p><strong><em><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Gangsar Wisata Tour and Travel adalah usaha jasa pariwisata dan perjalanan. </span><span style="vertical-align: inherit;">Kantor pusat berada di daerah Madiun, Jawa Timur. </span><span style="vertical-align: inherit;">Namun sampai saat ini proses pemesanan tiket masih dilakukan secara manual dan belum menerapkan informasi secara komputerisasi. </span><span style="vertical-align: inherit;">Dalam pengoperasiannya sering menemui berbagai kendala. </span><span style="vertical-align: inherit;">Selain itu, dalam penyimpanan data dan perekaman masih konvensional menggunakan data rekaman. </span><span style="vertical-align: inherit;">Lebih lanjut, hal ini menyebabkan pengoperasiannya menjadi lambat dan kurang optimal. </span><span style="vertical-align: inherit;">Kasing harus dikembangkan dan efisiensinya. </span><span style="vertical-align: inherit;">Untuk perubahan dan memaksimalkan potensi yang ada maka dibuatlah sistem informasi pemesanan paket travel secara online sebagai tujuan dari penelitian ini. </span><span style="vertical-align: inherit;">Sistem informasi ini berbasis web dengan menggunakan metode Waterfall. </span><span style="vertical-align: inherit;">Dalam pengujian, Blackbox Testing digunakan. </span><span style="vertical-align: inherit;">Mendapat hasil yang sesuai dan dinyatakan layak untuk digunakan. </span><span style="vertical-align: inherit;">Sistem informasi ini diharapkan dapat membantu pemilik dalam operasional bisnis jasa. </span><span style="vertical-align: inherit;">Pelanggan akan dengan cepat mendapatkan informasi layanan dan bertemu secara efisien dalam transaksi pemesanan.</span></span></em></strong></p> Amanda Aditya Khoirullina Samsul Hadi Copyright (c) 2023 JURNAL PILAR TEKNOLOGI Jurnal Ilmiah Ilmu Ilmu Teknik https://creativecommons.org/licenses/by/4.0 2023-12-29 2023-12-29 8 2 28 38 10.33319/piltek.v8i2.148 The RANCANG BANGUN APLIKASI SELEKSI PERANGKAT DESA MENGGUNAKAN METODE COMPUTER ASSISTED TEST (CAT) BERBASIS WEB (Studi Kasus Desa Ketawang) https://pilar.unmermadiun.ac.id/index.php/pilarteknologi/article/view/149 <p>Recruitment of village officials is an essential part of village development. Quality village governance <br>positively impacts public services and overall village development. Absolutely, village officials must be people who <br>has the high quality. However, there are often problems in recruiting village officials, such as limitations in <br>processing information from prospective village officials. The election of village officials in Ketawang village is still <br>done manually, using paper-based written tests. Based on these problems, a Web-Based Village Officials' Selection <br>Information System has been successfully built, especialy for Ketawang Village. The system was built using the <br>waterfall software development method and CodeIgniter framework. This system was built using the CAT (Computer <br>Assisted Test) system model. This system was created to assist the committee in the village Official's selection <br>activities more effectively and efficiently. Based on the test results, Black Box Testing produces an accuracy of up to <br>100%.</p> Dita Septy Kurniasari Kurniasari Copyright (c) 2023 JURNAL PILAR TEKNOLOGI Jurnal Ilmiah Ilmu Ilmu Teknik https://creativecommons.org/licenses/by/4.0 2023-12-29 2023-12-29 8 2 39 46 10.33319/piltek.v8i2.149 Menentukan Jurusan Perguruan Tinggi untuk Peserta Didik SMK Berdasar Nilai Raport serta Minat dan Bakat dengan Metode Decision Tree Algoritma C4.5 (Studi Kasus SMK Negeri 1 Donorojo Pacitan) https://pilar.unmermadiun.ac.id/index.php/pilarteknologi/article/view/169 <p>The purpose of this research is to create a good method to assist in making the right decision in selecting tertiary majors for class XII students at SMK Negeri 1 Donorojo, and also to help agencies, especially SMK Negeri 1 Donorojo and other SMK, to be able to make decisions to determine the potential of each student.
