The church is a spiritual institution for Christians. In the church there are various kinds of service activities, such as catechism services, baptism services, wedding blessing services, and social service services. In general, the Church in processing congregational service data, catechism data, baptismal data, marriage data is still recorded in the books, so that data can be lost or damaged, and it is less effective in searching data, because it takes a long time. In providing information such as worship agendas, church activities, and other routine church activities, it is still manual, namely through congregation bulletins. The purpose of this research is to build a website-based church service system model to support the implementation of various church services more effectively and efficiently. This study uses the PIECES analysis method to check and analyze the advantages and disadvantages that exist in the system. This system is designed using UML, to make it easier to design a website-based system. This church service information system provides features of church service activities and more complete information about the church that can be accessed more practically anytime and anywhere.

Radio tranceiver merupakan alat komunikasi yang masih cukup efektif dan relevan untuk membantu tugas-tugas harian terutama bagi para personil atau instansi yang bekerja di lapangan, namun saling terpisah di area yang luas secara geografis atau posisi medannya. Kondisi ini biasanya diperlukan karena belum tersedianya jaringan infrastruktur komunikasi permanen yang memadai seperti telephone atau internet.  Pada transmisi komunikasi analog, permasalahannya adalah di bagian antenna tuner yang di tuning secara manual agar tetap match dan menjaga nilai SWR agar tetap stabil, karena setiap kali merubah frekuensi maka nilai SWR (Standing Wave Ratio) juga akan ikut berubah. Jika nilai SWR lebih dari 1.5 maka transceiver dapat mengalami overheating. Untuk mengatasi masalah tersebut maka perlu dirancang sistem matching antenna tuner otomatis yang di kombinasikan antara Arduino nano dengan Android. Hasilnya pada saat merubah ataupun mengganti frekuensi pada radio maka sistem tunner berbasis arduino nano akan bekerja untuk memastikan nilai SWR tetap menunjuk pada nilai terendah. Sehingga kerusakan pada transceiver dapat terhindari.
