Technological developments in the modernization era both in the field of computers and other fields directly and indirectly spur us to be able to master the technology.Based on the situation analysis, the problems faced by the Maluku Protestant Church (GPM), Gidion Wayari Congregation (1 st party) and GPM Halong Anugerah Congregation (2 nd party) in the data management were the conventional / manual congregation data presentation which resulted in frequent errors in recording or data collection. which is repeatedly inputted (Data Redundancy), the data search process is very slow, operational costs are getting bigger, and the lack of human resources (HR) capabilities in using technology tools.With the implementation of Gpm Gidion Waiyari Ambon Information System Management Information Processing Training Data and Gpm Halong Anugerah Ambon Congregation, the solution to the problems by the first party and the second party can be resolved, namely the creation of an information system for congregation data management, preparation of IT operator personnel by training in operating Microsoft Office (Word, Exel, Power Point), and training for the operation of the Church Data Management Information System. ABSTRAKPerkembangan teknologi dalam era modernisasi dewasi ini baik dalam bidang komputer maupun bidang lainnya secara lansung maupun tidak langsung memacu kita untuk harus dapat menguasai teknologi tersebut.Berdasarkan analisa situasi, maka permasalahan yang dihadapi oleh Jemaat GPM Gidion Wayari (Mitra I) dan Jemaat GPM Halong Anugerah (Mitra II) dalam management pengelolaan data adalah penyajian data jemaat masih bersifat konvensional/manual yang mengakibatkan sering terjadinya kesalahan dalam pencatatan ataupun pendataan, data yang diinput secara berulang-ulang (Redudance Data), proses pencarian data sangat lambat, biaya operasional semakin membesar, dan kurangnya kemampuan Sumber Daya Manusia (SDM) dalam menggunakan perangkat teknologi.Dengan dilaksanakannya kegiatan Pelatihan Management Pengolahan Sistem Informasi Data Jemaat Gpm Gidion Waiyari Ambon Dan Jemaat Gpm Halong Anugerah Ambon, maka solusi terhadap permasalahan Mitra I dan Mitra II dapat teratasi yaitu pembuatan Aplikasi sistem informasi management data Jemaat, penyiapan tenaga operator IT Jemaat dengan cara melakukang pelatihan (training) pengoperasian Microsoft Office (Word, Exel, Power Point), dan melakukan pelatihan (training) pengoperasian Sistem Informasi Management Data Jemaat.

Energi merupakan sumber daya alam yang dapat diolah oleh manusia untuk memenuhi kebutuhan energinya. Dengan berkembangnya zaman, energi telah menjadi kebutuhan primer bagi manusia. Instalasi listrik rumah tinggal dalam hal ini baik rumah sederhana maupun rumah bertingkat adalah suatu sistem/rangkaian yang digunakan untuk menyalurkan tenaga listrik ke lampu atau perangkat listrik lainnya untuk menunjang kegiatan rumah tangga sehari-hari. Pembagian kelompok dalam instalasi listrik perumahan, baik rumah sederhana maupun rumah bertingkat sangat diperlukan, hal ini bertujuan agar seluruh bangunan tidak padam total ketika terjadi gangguan internal atau penggunaan listrik yang berlebihan. Permasalahan dalam penelitian ini adalah bagaimana memonitor konsumsi daya yang berlebihan di luar kapasitas mikrokontroler berbasis MCB, agar tidak terjadi trip saat menggunakan beban listrik yang berlebihan. Setelah melakukan penelitian dan pengujian alat monitoring arus dan tegangan listrik pada instalasi rumah tinggal berbasis mikrokontroler maka dapat disimpulkan bahwa trip pada instalasi perumahan dapat dihindari dengan menggunakan alat monitoring ini. Sistem monitoring dapat dilihat pada perubahan lampu indikator pada panel IoT dan aplikasi Blynk. Jika lampu indikator berwarna hijau, itu menandakan bahwa beban masih dalam kondisi normal. Lampu indikator kuning menunjukkan penggunaan beban di atas kondisi normal, sedangkan indikator merah menunjukkan beban pada salah satu kelompok instalasi harus dibatasi karena jika melebihi akan mengakibatkan trip.

Ambon Bay pollution had become a problem when in 1994, there was an algae bloom, which caused 34 people to get sick, and 3 of them died from eating shellfish that had been contaminated with poison from toxic phytoplankton. Since then, various mass media have reviewed and commented on the quality of the Ambon Bay waters. The highlight of the Ambon Bay pollution occurred when in November 2012, the Director-General of Marine Affairs and Small Islands (KP3K) of the Ministry of Marine Affairs and Fisheries (KKP) at that time, Eko Radiyanto, personally admitted that he was concerned about the pollution that occurred in Ambon Bay. Since then, the program "Kalesang Teluk Ambon or Save Ambon Bay" has been launched. The problem that has arisen is how the condition of the fertility of Ambon Bay since the save ambon Bay program was launched to date. The purpose of this study was to monitor the fertility of the Ambon bay in the last eight years since the Save Ambon bay program was launched. Monitoring was carried out from 2013 to 2020 by utilizing remote sensing technology by processing Aqua Modis satellite image data to determine the value of chlorophyll-a distribution as an indicator of water fertility. The results showed that in the first year of the Ambon Bay save the program, there was an increase in the fertility of Ambon Bay from 0.39 to 0.90 mg / m3, but after that, there was a decrease from year to year except in 2020, fertility increased dramatically from 0.31 to 1.00 mg / m3.

Phase-to-ground leakage in low-voltage network systems can cause transformer damage due to overload. Overloading on transformers is not caused by customer usage but rather by wasted electrical energy to the ground which causes losses. If there is a current leakage, the potential difference between neutral and ground is measured to produce a voltage value. Considering that there is little written about transformer damage caused by current leakage to ground in low voltage network systems, in this research a tool is made that can detect current leakage to ground in low voltage network systems using the ZMPT101B voltage sensor based on IoT. This research is in the form of design and manufacture of a leakage current detector to ground. The method used is the Research and Development method (research and development), namely in the form of observation, literature study. The research stage starts from a literature study in the form of finding references related to research, designing tools, making tools and programs, and testing the tools that are made. Based on the results of Based on the results of the research, this tool can detect leakage current to the ground from the lowest voltage of 24.3 Volts to the highest voltage of 184 Volts so that it can be displayed on the LCD and the blynk application and the system automatically sounds a buzzer as a warning of current leakage to ground. .
