Abstract

Di era digital saat ini perlunya teknologi informasi bagi masyarakat desa menjadi hal penting yang harus dipenuhi. Dalam hal ini pemerintah desa harus memiliki Sistem Informasi Desa  (SID) untuk masyarakat, dengan berbasis pada kemajuan teknologi informasi. Berdasarkan hasil pengamatan yang dilakukan, kondisi Kecamatan Nengahan Trimurti, Kabupaten Bantul Yogyakarta memiliki beberapa masalah utama, yaitu belum memiliki sistem informasi berbasis web di tingkat Dukuh terkait dengan profil dukuh, sistem informasi desa yang belum optimal untuk mendukung kegiatan administrasi pemerintahan. Metode program pengabdian masyarakat yang dilakukan sebagai solusi dari masalah yang ada untuk mendukung digitalisasi kelembagaan dusun berbasis teknologi informasi diantaranya pertama, identifikasi dan pengumpulan data akan dilakukan pada populasi dan data yang berkaitan dengan potensi dusun, melakukan manajemen data dan verifikasi data dan membuat format atau desain buku profil dusun dan papan monograf dukuh. Selain itu dapat meng-optimalisasi Sistem Informasi Desa dengan membuat situs web Padukuhan. serta, pemberian bantuan fasilitas modem untuk memperlancar jaringan internet di desa Nengahan sehingga dapat membantu pengelolaan situs website Desa Nengahan untuk digunakan secara berkelanjutan. Program Pengabdian melalui sistem informasi berbasis teknologi informasi ini telah dinyatakan masyarakat mampu memperkuat kelembagaan desa Nengahan, Trimurti, Srandakan, Bantul. Hal ini dilakukan melalui pembuatan buku-buku profil Buku dan monograf, pengembangan situs web dan media sosial, serta pelatihan dan bimbingan bagi petugas admin website. Guna mewujudkan digitalisasi kelembagaan berbasis IT ini, monitoring menjadi kunci untuk terjaganya efektivitas digitalisasi desa berbasis Sistem Informasi Desa

Abstract

This article discusses the manufacture of formaldehyde content test kit device. The device made can find out whether formalin or samples that are dropped are reagents, its characteristics can be processed electronically to determine the levels of formalin detected in the reagent/test kit. The design is made using AT89S51 microcontroller. Detection of formaldehyde levels using a color measurement method for reagent fluids consisting of R, G, and B values. Measurement of these color parameters using the TCS230 sensor. With this device, it is expected to facilitate health workers, especially health analysts, to automatically test the level of formaldehyde in food with a display on the LCD. The result of device test, this device is feasible to use by the percent error value of less than 10%.

Abstract

Motorcycle safety system has been provided by the manufacturer in the form of a handlebar lock and electrical key equipped with alarms. Keys provided by the manufacturers sometimes fail in securing a motorcycle. In addition the safety system does not provide position information of the stolen motorcycle to the owner. With these problems, the paper presents safety locked motorcycle equipped with artificial intelligence algorithms. Artificial intelligence algorithm is used to find and detect the location of the motorcycle using the shortest path algorithm. This paper applies search algorithm using Dijkstra algorithm where the algorithm is used to make the decision to get the location of the motorcycle. By using the algorithm, the location of the motorcycle can be detected but it is not able to find the shortest path needed. Therefore, this paper describes the modification of Dijkstra algorithm by adding a Fuzzy algorithm that is used for the weight values in decision making, so that it can pursue to find the shortest path.

Abstract

Biogas is a gas obtained from the breakdown of organic matter (such as animal waste, human waste, and plants) by methanogenic bacteria in an oxygen-free (anaerobic) state. The biogas produced mainly consists of 50-70% methane, 30-40% carbon dioxide, and other gases in small amounts. The gas produced has a different composition depending on the type of animal that produces it. It is challenging to obtain biogas concentration data because the monitoring equipment is currently minimal. Therefore, this research discusses how to make a monitoring system for biogas reactors. Sensors are installed in the digester tank and storage tank. The installed sensors are the MQ-4 sensor to detect methane gas (CH4), MG-811 sensor to detect carbon dioxide (CO2) gas, MQ-136 sensor to detect sulfide acid gas (H2S), and Thermocouple Type-K to detect temperature. The sensor will send a signal to the control unit in Arduino Mega 2560, then processed and displayed on the liquid crystal display (LCD). The sensor calculation results' accuracy is not much different from the reference based on the sensor readings. The sensor deviation standard is below 5.0, indicating that the sensor is in precision. The sensor's linearity of MQ-4 is 0.7%, the MG-811 is 0.17%, the MQ-136 is 0.29%, and the Type-K Thermocouple is 1.19%. The installed sensor can be used to monitor gas concentration and temperature in a biogas reactor.
