<![CDATA[Meningitis is generally an infectious disease of the lining of the brain and spinal cord with manifestations of fever and stiff neck. Prevention efforts for meningitis include vaccination. Meningococcal polysaccharide vaccine (MPSV4) is a type of quadrivalent meningitis vaccine recommended to control meningitis outbreaks. In storage, this vaccine uses a cold chain and cool box with a temperature between 2-8˚C. For vaccination activities, the vaccine is stored in a cool box with a cool pack provided to maintain temperature stability in the cool box. A cool pack itself is a rectangular plastic container that is filled with water and then cooled in a refrigerator at a temperature of 2-8°C for a minimum of 24 hours. From the existing problems, the author had the idea to create an IoT-based MPSV4 Meningitis Vaccine Cool Box Temperature Monitoring and Controlling System Design. The working system of this tool, namely TEC, will maintain the cool box temperature according to needs. If the dht11 detects that the temperature is too high then both TECs will turn on, whereas if the temperature is stable then one of the TECs will turn off. The temperature inside the cool box will be displayed on the LCD and also sent via the NodeMCU ESP8266 to the Firebase database which will then be displayed on the smartphone in real time.]]>

<![CDATA[KSP (Koperasi Simpan Pinjam) Makmur Mandiri bergerak dalam usaha perkreditan yang menyediakan pinjaman atau kredit sebagai mana koperasi pada umumnya. Sistem penerimaan pinjaman dalam KSP Makmur Mandiri yang sedang berjalan dilakukan dengan cara calon peminjam datang ke lokasi koperasi dengan mengajukan peminjaman kemudian karyawan mendata peminjam ke dalam form rekomendasi anggota setelah itu form rekomendasi anggota tersebut diberikan kepada pimpinan koperasi. Masalah yang terjadi pada KSP Makmur Mandiri adalah kehadiran pimpinan koperasi yang sering tidak ada di koperasi, sehingga pengajuan pinjaman yang ada di koperasi menumpuk dan tidak dapat segera di tentukan hasil kelayakan pinjaman. Selain itu masalah yang juga terjadi di koperasi adalah penilaian yang dilakukan pimpinan dalam menentukan kelayakan pinjaman masih bersifat subyektif yaitu hanya memberikan keputusan layak atau tidak seorang peminjam, tanpa memperhitungkan persentase nilai kelayakan pinjaman tersebut. Solusi untuk menyelesaikan masalah ini maka dibuatlah sebuah keputusan penentuan kelayakan yang mampu membantu pimpinan dalam proses penilaian dan memberikan perhitungan tepat dalam menilai kelayakan pinjaman. Metode yang dapat mendukung keputusan adalah Fuzzy logic, karena penilain yang bersifat subyektif atau non-linear dapat dimodelkan dan dihitung secara tepat.]]>

<![CDATA[Improving English Vocabulary Proficiency by Using Save the Hangman Game Method to Students of Class VIII B in SMPN 11 Pontianak in Academic Year 2022-2023. This study aimed to enhance English vocabulary proficiency among eighth-grade students in Class VIII B at SMPN 11 Pontianak during the 2022-2023 academic year using the Hangman game method. It employed a Class Action Research approach, focusing on implementing the Save the Hangman game at SMPN 11 Pontianak. The research consisted of two cycles involving planning, action, observation, and reflection. Data collection instruments included observation sheets for student and teacher activities, vocabulary tests, and a questionnaire. The findings indicated a 7% increase in vocabulary skills from the first cycle (62%) to the second cycle (70%), reaching the passing criteria of a score above 61. The quality of teacher activity improved by 10%, from 64.52% in the first cycle to 74% in the second cycle. Additionally, student engagement in active learning increased by 14% for very active criteria (from 41% to 55%) and by 16% for active criteria (from 29% to 45%). However, the percentage of students considered active enough decreased by 5% (from 14% to 9%), and no students fell into the less active criteria in the second cycle.]]>

<![CDATA[The availability of clean water is a crucial factor in supporting sanitation and health in Islamic boarding schools, especially for bathing, washing, and toilet (MCK) facilities. Pondok Ma’had Al-Aqwam MAN Kendal faces poor water quality issues, such as murky water, unpleasant odors, and unsuitable acidity levels. This study aims to develop an Internet of Things (IoT)-based water quality monitoring information system to support real-time sanitation management in boarding schools. The system is designed using an ESP32 microcontroller integrated with pH, turbidity, and temperature sensors, displaying data directly through the Android-based Blynk application. It also includes an automation logic that activates the filtration pump when the pH or turbidity values fall outside the normal range. Testing results indicate that the system can accurately read and display water conditions and perform automatic re-filtration when water is deemed unfit for use. Expert and user validation yielded an average score of 90%, indicating the system is highly feasible for clean water management in boarding schools. Therefore, this system offers a practical and efficient solution for continuously monitoring and maintaining water quality.]]>

<![CDATA[Design and Development of Fire Monitoring System Based on Internet of Things Using Flame Sensor and Smoke Sensor (Case Study at Balai Desa Dlimas). Fire is a disaster that can cause significant losses in both material and human life. Early fire detection is crucial to minimize the potential impact. Balai Desa Dlimas, located in Banyuputih District, Batang Regency, currently lacks an adequate fire detection and monitoring system. Therefore, this study aims to design and implement a fire monitoring system based on the Internet of Things (IoT) using an ESP32 microcontroller, a flame sensor, an MQ-2 smoke sensor, and a DHT22 temperature sensor. The research method used is Research and Development (R&D) with a prototyping model. The system is designed to detect the presence of fire, smoke, and room temperature in real time. Data from the sensors is processed by the ESP32 and sent to the Blynk application to notify users. Warning outputs are also provided through a buzzer and LED lights as on-site alerts. The test results show that the system can detect fire, smoke, and temperature increases with high accuracy. Users can receive real-time notifications via the Blynk application within less than 3 seconds of fire detection. This system is expected to help Balai Desa Dlimas minimize fire risk and can be further developed for implementation across various public facilities.]]>
