Abstract

Particulate Matter is an air pollutant substance that surrounds humans both indoors and outdoors. Humans cannot see or know the levels of pollution particles in the air and air quality without tools. Therefore, a prototype "Raspberry Pi-Based Air Quality Monitoring System" was made. This system consists of a tool, which can determine the level of pollution in the air, especially PM 2.5 and PM 10 and to detect the surrounding environmental conditions such as temperature, humidity, and air pressure, several sensors are needed. For the detection of PM 2.5 and PM 10 the PMS5003 sensor is used and for the detection of environmental conditions using the SHTC3 (air temperature and humidity) and LPS22HB (air pressure) sensors which are available in the Sense Hat B module. For the reading process using a Raspberry Pi programmed using Python and data will be processed into an Air Quality Index based on the “Polutant Standards Index”. In this study, the input specifications were tested. In the input specification test, there is a match between the Air Quality Index trend based on the location and time of data collection

Abstract

Teknologi akuakultur bioflok merupakan metode menjaga kualitas air dalam budidaya ikan. Penjagaan kualitas air dilakukan dengan mengubah nitrogen anorganik menjadi nitrogen organik yang tidak bersifat toksik menggunakan bakteri. Bakteri ini dapat mengkonversi limbah organik menjadi kumpulan mikroorganisme berbentuk flok yang dimanfaatkan oleh ikan sebagai sumber makanan. Namun metode bioflok memerlukan pemantauan air secara teratur untuk menjaga kualitas air. Oleh karena itu pada penelitian ini dirancang bangun sebuah sistem yang dapat menjaga kualitas air pada kolam ikan bioflok berdasarkan suhu air, TDS air, dan pH air menggunakan komunikasi Long Range agar dapat memantau dan mengontrol kolam dari jarak jauh. Alat yang digunakan untuk komunikasi Long Range adalah LoRa RFM95W. Hasil pengujian pengiriman data menggunakan LoRa dalam keadaan LOS dapat diterima hingga jarak 300 meter dengan nilai RSSI adalah -100dBm. Semua sensor dapat bekerja dengan baik seperti sensor suhu air, TDS air, dan pH air yang dapat membaca perubahan nilai yang terjadi pada air kolam bioflok tiap waktu. Selain itu, pemberian pakan ikan secara otomatis dapat dilakukan sesuai jadwal yang ditentukan dengan bantuan modul RTC. Respon yang diberikan saat kondisi air tidak dalam batas normal juga dapat berjalan baik dengan menyalakan buzzer dan menampilkan notifikasi pada aplikasi.

Abstract

Geographic Information System (GIS) is a technology used to manage spatial data in various applications. This study creates a web-based GIS system design for PT. Aba Telekomunikasi Indonesia, which faces challenges in managing customer data and ODP. The A-star algorithm is applied to find the shortest route between ODP and customers. The system is developed using the CodeIgniter framework, PHP, MySQL, and leaflet.js for map visualization. Testing is carried out by comparing the results of the A-star algorithm with Google maps and using UAT (User Acceptance Test) for user acceptance analysis. The results show an average distance difference of 0.0095 km, meeting a tolerance of 0.2 km, and a user acceptance rate of 84.06%. This study proves that GIS can improve the operational efficiency of small-scale telecommunications companies.

Abstract

The rapid development of digital technology has affected many sectors, including the tourism sector. Utilizing digital platforms, such as websites, is an option for promoting tourist areas. Kampung Setaman is an area that has the potential to become an educational tourism destination. However, this village does not yet have a website as a promotional medium for its village. Therefore, this research aims to develop a website for the Kampung Setaman Tourism Village which is expected to help the Kampung Setaman management in promoting the area more widely. Creating a website begins with a needs analysis to find out what menus need to be on the website. Next, the website interface was designed using HTML, CSS, Javascript and PHP, as well as creating a database using MySQL. Collecting and creating website content in the form of writing, photos and videos about the area and programs of Kampung Setaman is also carried out to then be uploaded on the website being developed. The final stage of creating a website is testing performance efficiency and security. Based on performance efficiency testing, an average performance value of 90.2% was obtained. Meanwhile, from security testing using HostedScan, it was found that website security was quite good.
