Suhu dan kelembaban merupakan parameter lingkungan yang harus dijaga pada ruang kubikel untuk memastikan peralatan distribusi listrik tetap bekerja secara optimal. Pada multi-kubikel, perbedaan fungsi dan beban menyebabkan karakteristik suhu dan kelembaban pada tiap ruang kubikel tidak sama, sehingga pemantauan secara manual menjadi kurang efektif dan efisien. Penelitian ini bertujuan untuk merancang dan membangun prototype sistem monitoring dan kontrol suhu-kelembaban pada multi-kubikel berbasis Internet of Things (IoT) yang terdiri dari tiga buah kubikel. Sistem ini menggunakan ESP8266 sebagai mikrokontroler utama dan sensor DHT20 sebagai sensor suhu dan kelembaban yang masing-masing dipasang pada kubikel dengan kondisi lingkungan berbeda. Sistem dilengkapi dengan aktuator kipas dan lampu, serta notifikasi real-time melalui LCD dan Telegram. Meskipun kontrol dan monitoring dilakukan secara terpisah pada tiap kubikel, notifikasi kondisi seluruh kubikel terintegrasi pada satu kanal Telegram yang sama. Pengujian kinerja sistem dengan memberikan variasi suhu dan kelembaban yang berbeda untuk tiap kubikel. Kubikel 1 diberi kondisi normal (suhu 35°C-40°C dan kelembaban 50%-70%), kubikel 2 diberi kondisi overheat (suhu di atas 40°C), sedangkan kubikel 3 diberi kondisi overhumidity (kelembaban > 70%). Hasil pengujian menunjukkan sistem mampu melakukan kontrol suhu dan kelembaban dalam ruang multi-kubikel serta mengirimkan notifikasi melalui Telegram dengan tingkat keberhasilan 100% dan rata-rata delay 5,6 detik.

PAMTIRTA Tempino is an institution that provides clean water services in the Tempino area. The process of recording water use and monitoring water turbidity is still done manually, making it prone to recording errors and making it difficult to monitor the water quality distributed to the community. This study aims to design a website-based water turbidity recording and monitoring system by focusing on User Interface (UI) and User Experience (UX) aspects using the Design Thinking method. The research follows five stages of Design Thinking: empathize, define, ideate, prototype, and test. Data collection involves observation and in-depth interviews with PAMTIRTA officers. The results include a design with key features such as digital water meter recording, turbidity monitoring dashboards, and complaint services. The prototype was tested using Maze and the System Usability Scale (SUS), achieving a score of 80.1 and falling into the "Good" category (grade B). These results demonstrate that the UI/UX design effectively provides an easy-to-understand, operationally suitable, and efficient solution for PAMTIRTA Tempino's water recording and turbidity monitoring needs. This design offers a ready-to-implement solution to improve the efficiency, accuracy, and quality of clean water services in the Tempino area.

Management of school funds in the form of SPP (Educational Development Donations) at the Kranggan foundation sourced from kindergarten, elementary and junior high schools so far is still managed manually, making it difficult and takes a long time for the Administration to check lists for students who have made payments. Every month. In this study, an SPP payment system was made using an SMS Gateway with the web scraping method. In the development process using the prototype method. The researcher aims to develop a web-based information system that is expected to help manage school payment data for the better. The information system will be equipped with an SMS feature that will be sent to the parents of the students concerned so they can know that the school payment has been made. This SMS feature is also useful for sending reports of late payments or SPP arrears to parents of students whose children are late in paying tuition fees. With this program, students can also make tuition payments in two ways. The first is manually or submitting payment to the TU at the school. The second is by means of money transfer payments through banks.

Decision Support System in Employee Performance Appraisal is a web-based system used to support decision making for outsourcing employee contract extensions. This study aims to provide a decision support information system in employee performance appraisal so that employee performance appraisals and employee contract extension decisions can be carried out systematically.

The community's need for electricity is getting higher, so alternative energy sources such as solar heat are needed to replace energy sources from fossil fuels in meeting electricity needs. In this paper we design a two-axis solar tracker with an LDR sensor. A sun tracking system is a unit that is combined into one to control the position of the tracking device with the aim of making the surface of the solar panel module always facing the direction of sunlight. This research discusses the Prototype of the Sun Tracking System in Arduino Based Solar Power Generation Systems to get maximum solar energy. This system will make solar panels move automatically so that sunlight absorption can be maximized. The main control uses Arduino nano which gets input values ​​from the LDR sensor then is processed to the output system. With the control system method can automatically be seen the difference in the results of a fixed solar panel with a solar panel with a tracker, from the comparison we get a solar panel with a tracker to get more optimal results.
