This research created a phase angle monitoring tool based on the Internet of Things (IoT) using the blynk application, apart from monitoring phase angles it also monitors voltage, current and power factor. </span></span>The method used is an experimental method, which starts with hardware design using a Node MCU where the Node MCU will later convert analog electrical quantities to digital while the PZEM 004-V30 sensor contains a voltage sensor and a current sensor which detects analog quantities sent to Node MCU, software design using Arduino IDE and IoT using the Blynk application then testing the tool created. Testing for measuring and monitoring phase angles and reactive power will be compared with the Haiko clamb meter so that the measurement error presentation can be seen. The presentation of phase angle measurement errors for loads of 1x36 Watt, 2x36 Watt, 3x36 Watt and 4x36 Watt respectively are 4.32%, 3.40%, 1.77% and 1.32%. The error is below 5%, so the performance of this tool can be said to be good. The highest error presentation was 4.52% for the 1x36 Watt TL lamp load, while the smallest error presentation was 1.32% for the 4x36 Watt TL lamp load.</p>2023-10-29T13:41:10+08:00Copyright (c) 2023 ramly rasyid, Miftah Muhammad, Rahman R Rasyidhttps://ejournal.unkhair.ac.id/index.php/josae/article/view/6899PROTOTYPE PEMBERI PAKAN AYAM OTOMATIS BERBASIS INTERNET OF THING’S2023-12-12T08:03:12+08:00Rizky Abdul Salamrizkyabdulsalam62497@gmail.comSuryadhi Suryadhirizkyabdulsalam62497@gmail.comMuh. Taufiqurrohmanrizkyabdulsalam62497@gmail.com<p>Livestock is a livestock breeding activity that aims to produce livestock products and benefits from their activities. Broiler is one of the promising livestock business. This is evidenced by the increasing consumer demand for household and consumer consumption on the scale of restaurants every day, therefore in the livestock management system it is necessary to increase the amount of production in producing quality products. Internet of things (IoT) is the right step for farmers in implementing daily activities, using an automation system so that the crew (the crew of the cage) are not too busy checking the cage. this is what underlies the manufacture of tools that can be controlled virtually with a system for monitoring and controlling chicken feeding with the internet and the help of applications on smartphones. The system for making automatic feeders based on the Internet of Things is in the form of a prototype as a remote control tool and can especially be helped by using components such as an ESP8266 WiFi module or an Arduino Uno microcontroller, DC gearbox motor, servo motor, ultrasonic sensor, this tool is also made aims to reduce the level of loss as in previous studies due to the presence of leftover feed in the automatic feeder, so for the next research to be made, it will be optimized by the absence of feed residue in the automatic feeder container.</p>2023-11-14T13:43:57+08:00Copyright (c) 2023 Rizky Abdul Salam, Suryadhi Suryadhi, Muh. Taufiqurrohmanhttps://ejournal.unkhair.ac.id/index.php/josae/article/view/6900Rancang Bangun Aplikasi Mobile Berbasis Android untuk Monitoring Sistem Solar Tracker2023-12-12T08:03:31+08:00Mohammad Anthonimohammad.131170436@student.itera.ac.idSabhan KanataKanatasabhan@gmail.comGde KM AtmajayaAtmajayagde@gmail.com<p>The solar tracker is used to adjust the tilt angle of the solar panels automatically so that they are always perpendicular to the direction of the sunlight. To optimize the monitoring process for the parameters of the solar tracker system, the monitoring process needs to be carried out remotely and in real time through a mobile application. Based on this, the author tries to design an application for monitoring the solar tracker system. This application development uses a waterfall development model which consists of determining specifications, designing, implementing, and testing applications. The application development process uses the Flutter Software Development Kit (SDK) and Firebase as the database. User experience testing using a questionnaire with 32 respondents. The result of the implementation is an android-based application. This application has the main features for monitoring the parameters of current, voltage, energy, and power from solar panels and batteries. This application has a login feature. The application also has a power parameter graph and power parameter history list. The application also has user profile and about application features. This app can receive data from Firebase in realtime. The user experience test results are grouped into 6 categories, namely stimulation, attractiveness, novelty, efficiency, perspicuity, and dependability. Each rating for each category is 0.99, 1.43, 0.77, 1.23, 1.13, and 1.18 with a scale of -1 to 2.5. All features in the application can function properly. Then, the level of user experience is above average for the categories of dependability, efficiency, novelty, and attractiveness.</p>2023-11-14T14:17:04+08:00Copyright (c) 2023 Mohammad Anthoni, Sabhan Kanata, Gde KM Atmajayahttps://ejournal.unkhair.ac.id/index.php/josae/article/view/6898RANCANG BANGUN ALAT PENDETEKSI KANTUK PADA KENDARAAN RODA EMPAT DENGAN METODE HAAR CASCADE2023-12-12T08:03:48+08:00satria aditama yadavia achmadsatria.aditama.sa62@gmail.comSuryadhi Suryadhisatria.aditama.sa62@gmail.comJoko Suburjokosubur@gmail.comBased on the Surabaya Police Traffic Unit, the number of accidents due to traffic violations in Surabaya from January to August 2019 reached 882. One of the biggest causes of accidents is caused by human error. One of the human error factors is fatigue or sleepiness. Sleepiness is a very common thing that happens to everyone. This can be caused by various factors, namely fatigue, lack of sleep, overeating. Drowsiness can be defined as a process produced by circadian rhythms and the need for sleep. In a drowsy state, a person can increase the blink of an eye as much as 20% of the frequency of blinks per minute. In addition, a person experiences microsleep with a duration of eye closure of 0.5 seconds or more. The eye recognition process carried out by computer vision is not as easy as what is done by humans directly. While humans themselves are very easy to recognize someone very quickly without having to think long. While computer vision is very slow in recognition. So in this research, a sleep detection device with facial recognition will be made which detects sleepiness in the eyes for safety when driving on the highway so that it can reduce the risk of accidents on the highway, using a raspberry pi microcontroller using the Haar Cascade method which requires very fast eye recognition. It is hoped that from my research this tool can reduce the number of accidents in Indonesia, especially in East Java, the city of Surabaya.2023-11-14T15:02:56+08:00Copyright (c) 2023 satria aditama yadavia achmad, Suryadhi Suryadhi, Joko Suburhttps://ejournal.unkhair.ac.id/index.php/josae/article/view/7006EVALUASI LAJU PRODUKSI MINYAK PADA SUMUR X STUDY PADA PT. CITIC SERAM ENERGY LIMITED, KABUPATEN SERAM BAGIAN TIMUR, PROVINSI MALUKU2023-12-07T10:30:46+08:00Syarifullah Bundangbundangsyarifullah@gmail.com<p class="Default">Minyak dan gas bumi merupakan salah satu kebutuhan yang harus dipenuhi oleh setiap Negara. Indonesia merupakan negara penghasil minyak dan gas bumi namun belum mampu memenuhi kebutuhan minyak nasional, sehingga pemerintah harus mengimpor untuk mencukupi kebutuhan bahan bakar minyak, seperti pada tahun 2010 impor minyak mencapai 64 ribu kilo liter perharinya. Seiring berjalannya waktu produksi minyak dan gas bumi yang dihasilkan akan menurun disebabkan beberapa sumur yang semakin tua atau (mature field) dan ketika tekanan reservoir akan semakin rendah maka mengakibatkan menurunnya kapasitas produksi formasi. Tekanan dan kedalaman sumur sangat berpengaruh terhadap produksi minyak bumi yang dihasilkan. Selain itu siklus hidup sumur juga sangat penting diperhatikan untuk mendapatkan minyak bumi yang banyak. Berdasarkan observasi pada 28 sumur diantaranya sumur X mengalami penurunan jumlah produksi. Untuk itu solusi agar meningkatkan laju produksi minyak secara optimal dilakukan dengan menggunakan pemasangan <em>artificial lift. </em>Metode yang digunakan untuk menghitung laju alir produksi pada sumur X adalah kurva IPR 2 fasa metode <em>vogel </em>dan menentukan jenis <em>electrical submersible pump </em>menggunakan skenario perencanaan <em>artificial lift</em>. Hasil analisis kurva IPR <em>vogel </em>pada sumur X didapatkan laju alir produksi (qmaks) 223.172 bfpd dengan Water Cut Sebesar 72%.</p><p><em>Kata kunci: minyak bumi, sumur produksi, artificial lift, metode vogel.</em></p>2023-11-24T17:30:34+08:00Copyright (c) 2023 Syarifullah Bundanghttps://ejournal.unkhair.ac.id/index.php/josae/article/view/7510STUDI KARAKTERISTIK PADA BASED-PLATE SISTEM ANGKUR DENGAN DAN TANPA GEOTEXTILE2024-02-11T14:42:21+08:00Irnawaty Irnawatyinnacivilumi@gmail.comSlope stability is a fairly broad field, considering that of the several types of geotechnical<div>construction failures, the largest is slope stability failure. Of the several types of natural disasters that occur in Indonesia, floods and landslides are at the top of the list of victims. The aim of this research is to examine the characteristics of based-plate anchor systems with and without geotextiles. The basic concept of an anchored geosynthetic system is to increase compression in the soil under the geosynthetic by driving the anchor to a certain depth. With additional compression on the soil, soil compaction will occur so that the frictional strength of the soil increases. The research carried out included testing in the laboratory. This research will be carried out at the Soil Mechanics Laboratory of the Civil Engineering Department of Hasanuddin University, Makassar. The sample is disturbed soil originating from the location in front of the Laboratory of the Faculty of Engineering, Hasanuddin University, Makassar, South Sulawesi. The relationship between based-plate geometry and load for a tensile load of 2500 kg and a decrease in soil deformation of 0.18 cm. Based on research conducted with a geotextile distance of 15 cm per layer, it can increase tensile strength and reduce the settlement that occurs. An increase in the anchor tensile load results in an increase in soil deformation.</div>2024-02-11T14:41:10+08:00Copyright (c) 2023 Irnawaty Irnawaty
