Abstract

Bahan partikulat dengan ukuran lebih kecil dari 10 μm (PM10) telah dikaji dalam berbagai penelitian sebagai salah satu polutan utama di udara. Monitoring PM10 dibuthkan untuk mengevaluasi kualitas udara pada area spesifik. Propinsi Jambi hanya memiliki tiga stasiun pengukuran kualitas udara, dan satu diantaranya tidak aktif. Informasi polusi PM10 yang didapatkan dari kedua stasiun lainnya hanya tersedia di situs Kementrian Lingkungan Hidup dan data diakumulasi sekali tiap hari. Batasan-batasan tersebut merupakan latar belakang dari penelitian ini untuk merancang alat pengukur PM10 yang portabel, mudah digunakan, rendah biaya, dan simultan. Sensor debu GP2Y1010AU0F digunakan sebagai penghitung PM10 dengan metode optik dan frekuensi 280ms. Data keluaran dari sensor diproses oleh mikrokontroler menggunakan formula kalibrasi yang disediakan oleh pabrik sensor tersebut. Informasi konsentrasi PM10 ditampilkan di layar LCD dan disimpan dalam mikroSD. Uji performa dilaksanakan di Mendalo, Universitas Jambi pada 7 Maret (16.00-18.00), 8 Maret (12.00-14.00), dan 11 Maret 2017 (08.00-10.00). Hasil masing-masing pengukuran menunjukkan bahwa konsentrasi PM10 adalah 145.6 μg/m3, 149.5 μg/m3, dan 157.7 μg/m3. Merujuk pada PP No. 41 (1990), hasil yang didapatkan pada tanggal 11 Maret 2017 melebihi standar kualitas partikulat (150 μg/m3). Alat ini berpotensi untuk dikembangkan lebih lanjut sebagai instrumen monitoring kualitas udara.

Abstract

The water pressure monitoring system in the PDAM pipeline networks has been successfully developed for operation and maintenance of water leaks in a real-time manner. This research aims to design a water pressure monitoring system in operational piping networks to identify anomalies as early as possible. The system is built using a microcontroller, a 1.2 MPa fluid pressure sensor and a control system equipped with a GSM wireless communication module, an Analog to Digital Converter module with 16-bit resolution, a real-time clock peripheral, an OLED display 128x64, and a micro SD card. The developed system was tested in a pressure range of 0.200 - 0.800 bar with 30 repetitions with a RMSE of 0.058 bar. This system has a deterministic coefficient of 0.885 against a standard manometer. The system implemented in the field successfully sends data to the server with a success rate of 96.0%. Data is displayed on a monitoring dashboard that can be accessed via a computer or smartphone.

Abstract

Gas karbon monoksida (CO) merupakan salah satu zat pencemar udara dalam ruangan yang memiliki sifat tak berwarna, tak berbau, dan tak berasa sehingga sulit dideteksi oleh panca indra manusia. Penelitian ini bertujuan untuk merancang-bangun sistem pemantau kualitas udara di dalam ruanga khususnya gas CO dalam ruangan secara waktu nyata dan akurat. Sistem dibangun menggunakan sensor CO berupa MQ-7, sistem pengendali utama ESP8266 AT2560 Robodyn, sensor temperatur dan kelembaban relatif udara DHT22, penanda waktu RTC, dan dashboard monitoring yang terkoneksi dengan Grafana yang telah dibangun dengan bahasa pemrograman Go-Lang untuk menerima data yang dikirimkan oleh sistem. Hasil pengujian di dalam ruangan bangunan rumah tipe-38 selama 24 jam menunjukkan bahwa kadar CO rata-rata di dalam ruangan sebesar 11ppm dan telah melebihi baku mutu yang ditetapkan oleh PERMENKES Nomor 1077/MENKES/PER/V/2011. Tingkat kenyamanan termal berada pada kondisi nyaman optimal (22.8 – 25.8°C) dengan nilai rata-rata temperatur sebesar 25.7 °C, sedangkan kelembaban relatif rata-rata sebesar 65 % berada pada kondisi diatas kelembaban yang dianjurkan (40 – 50 %). Kinerja pengiriman data menunjukkan bahwa packet loss sistem sebesar 0.83% yang termasuk dalam kategori sangat bagus.

Abstract

Air pollution has a negative impact on the environment and human health. Meanwhile, the number of conventional air quality monitoring stations is minimal due to high procurement and operational costs. This study proposes a nitrogen dioxide (NO2) pollutant measurement system using the metal oxide sensor (MOX) sensor and cellular network for data transmission in the measurement area. A calibration curve is used to measure NO2 levels based on the sensor's internal resistance changes. Measurement data of NO2 concentration, air temperature, relative humidity, and geospatial information are compiled and sent via global positioning system (GSM), general packet radio service (GPRS) radio communication with transmission intervals of every minute. The database server processes the data and displays it on the web application. System testing results at the Tugu Kujang Bogor at 15:38:00-16:38:00 September 23, 2021, showed that the concentration of NO2 ranged from 0.16-0.52ppm with an average of 270 ppb with an AQI of 133 in the unhealthy category for the sensitive group. The measured NO2 levels are outside the range of the NO2 concentration database in the industrial areas of Bogor and Jakarta for the 2016-2020 period. Therefore, this system provides an excellent opportunity to obtain real-time measurement data in the field.

Abstract

In carrying out a construction project, the project should be a solid building and have a long life. Criteria and characteristics of a good building of course. It should be realized that changes may occur in the future and will affect the pattern of the plan it self. The length of time for project completion has a major impact on the increase in overall project costs. has been completed or implemented When viewed from the amount of work completed, the concept of Earned Value is one of the control methods used to control project costs and time in an integrated manner. This method is used to analyze implementation performance and make project completion estimates that provide information on project performance in a reporting period and produce cost and time estimates for the completion of all project work. This project is planned for 204 days or about 29 weeks with a contract value of Rp. 106,671,014,961.00

Abstract

Shallots (Allium ascalonicum L.) are a high-value vegetable commodity that is strategically important for the Indonesian economy. However, shallot cultivation, particularly watering and fertilization, is still largely done manually, requiring human labor and simple equipment, making it less efficient and prone to errors in environmental monitoring. This study aims to design an Internet of Things (IoT)-based shallot microclimate monitoring system in greenhouses to improve the efficiency of automatic environmental monitoring. The method used includes the development of an ESP32 microcontroller-based system integrated with soil moisture sensors, temperature sensors, and air humidity sensors, as well as a GSM/GPRS wireless communication module for real-time data transmission. The system is also equipped with an alarm module to provide early warnings of unsuitable environmental conditions. Test results show that the system is able to operate stably and effectively in automatically monitoring microclimate changes in greenhouses. In conclusion, this IoT-based monitoring system can support more efficient shallot greenhouse management and reduce reliance on manual monitoring.
