Rural areas play an important role in supporting the circulation of a people-based economy through equitable development. One form of development that villages need is infrastructure. Difficult access to infrastructure causes villagers to urbanize in the city. This condition was also experienced by ABC Village before the Nawa Cita program, which made the flow of infrastructure development run massively. The infrastructure development process requires support and cooperation between the village government and the village community. This research examines the impact of infrastructure development and its risks. The results of the study of village government policies and the role of the community have a positive effect on the success of infrastructure projects. Model measurement with the SEM method is fit. The results of the risk analysis showed that there were 5 high-category risks, 12 medium-category risks, and 14 low-category risks. Kawasan desa memegang peranan penting dalam mendukung perputaran ekonomi berbasis kerakyatan melalui pemerataan pembangunan. Salah satu bentuk pembangunan yang dibutuhkan desa adalah aspek infrastruktur. Sulitnya akses infrastruktur menyebabkan warga desa melakukan urbanisasi ke kota. Kondisi ini juga dialami oleh Desa ABC sebelum adanya program Nawa Cita yang membuat arus pembangunan infrastruktur berjalan masif. Proses pembangunan infrastruktur membutuhkan dukungan dan kerja sama antara pemerintah desa dengan masyarakat desa. Penelitian ini mengkaji terhadap dampak pembangunan infrastruktur dan risikonya. Hasil kajian terhadap kebijakan pemerintah desa dan peran masyarakat berpengaruh positif terhadap keberhasilan proyek infrastruktur. Pengukuran model dengan metode SEM bernilai fit. Hasil analisis risiko diketahui bahwa terdapat 5 risiko kategori tinggi, 12 risiko kategori sedang dan 14 risiko kategori rendah.

In the hydroponic deep flow technique (DFT) system, in general, the measurement of water quality parameters is still done manually and because of this it often results in delays in adding nutrients, causing yellowing of plants. This study aims to design and realize a prototype system for automatic monitoring and replenishment of water supply, pH (acidity), and nutrients in DFT hydroponics based on Arduino UNO and the internet of things. The system is built with Arduino UNO, pH sensor, TDS sensor, HC-SR04 sensor, DC water pump, NodeMCU, ThingSpeak and Blynk applications. The results showed that the system prototype was able to work well. The difference in the measurement results by the sensor compared to the reference measuring instrument is relatively small, namely the difference in pH 2.058%, TDS 0.835%, distance 0.255% and pH control 0.43%, TDS 0.404%, and volume 0.69%. The system prototype has succeeded in maintaining the pH level of the solution, the TDS of the solution, and the quality of the water in the system. Pada system hidroponik deep flow technique (DFT), secara umum pengukuran parameter-paramter kualitas air masih dilakukan secara manual dan karenanya sering mengakibatkan keterlambatan penambahan nutrisi sehingga membuat tanaman menguning.

In mushroom greenhouses at IKM Simbang Maros, watering is currently done manually using a hose and scheduled twice daily, without considering the optimal temperature and humidity for mushroom growth. This study aims to develop an automatic watering system for oyster mushroom cultivation using a DHT22 sensor to monitor temperature and humidity. The system is equipped with a NodeMCU ESP32 microcontroller and a mist sprayer, triggered by a relay to activate the water pump. An IoT platform using Thingspeak allows farmers to monitor temperature and humidity data in real-time on their smartphones. In a real case study, the device effectively maintained optimal humidity levels for mushroom growth, with the pump activating when humidity was below 85%. Data from 10 observations showed that the pump was active for 7 times. Data processing using R Studio showed the system's ability to stabilize humidity levels. The proposed system could help farmers optimize mushroom growth and reduce the labor required for manual watering.

The purpose of this study was to determine the relationship between road slope and total resistance to Dump Truck fuel consumption. Based on the calculations, the relationship between road slope and fuel consumption is obtained using the regression equation for when loaded Y = 0.0817X +1.831 and when empty Y = 0.0344X + 0.787. While the relationship between total resistance and fuel consumption when loaded with the regression equation Y = 0.0012X +1.8229 when loaded and Y = 0.001X + 0.5789 when empty. The recommended recommendation to reduce dump truck fuel consumption is by improving the road slope according to the standard, which is 8%. After repairing the road slope, the company can save fuel consumption of 87.07 liters/day for 14 dump trucks with an estimated savings of Rp.1,105,764.87 per day.

The Velocity Air Intake System is an important component in a motor vehicle engine, particularly in a 155cc engine. Its function is to optimize the airflow process to the throttle body or carburetor. However, many users or people tend to overlook the significance of improving engine performance by varying the model or replacing the velocity air intake system itself. One common issue is the diameter and shape of the airflow model, which can affect the power, torque, and exhaust emissions produced. Installing a velocity air intake system is one approach to achieve an efficient air delivery process into the combustion chamber. In our research conducted using a dyno test on a 155cc four-stroke engine, the results showed that using a 46 mm size yielded the highest power of 11.03 Hp and produced a torque of 12.39 N.m. Using a 47 mm size resulted in 11.02 Hp and decreased the torque to 12.28 N.m. With a 48 mm size, there was a decrease in power to 11.00 Hp and an increase in torque to 12.72 N.m, while using a 45 mm size led to a decrease in power to 10.09 Hp and produced a torque of 11.31 N.m.

Broiler chicken is a superior breed that has high productivity. Ammonia odor that pollutes the area around the cage is a problem in broiler management. Due to the activity of microorganisms in feces, unabsorbed protein amino acids, and other non-protein nitrogen (NPN) compounds break down into ammonia gas. In addition to damaging the environment, NH3 gas can interfere with animal performance, making them susceptible to disease. This research aims to solve the problem that comes from ammonia by measuring and designing an automatic ammonia gas controller based on Arduino using an MQ-135 sensor. If ammonia levels in the cage are greater than 5 ppm, ammonia levels are controlled by spraying liquid smoke to limit ammonia gas emissions. The results of this study show that the tool is able to reduce ammonia gas levels to 8 ppm. Ayam broiler adalah jenis ras unggulan yang memiliki daya produktivitas tinggi. Bau amoniak yang mencemari area sekitar kandang menjadi masalah dalam pengelolaan ayam broiler. Karena aktivitas mikroorganisme dalam feses, protein yang tidak diserap asam amino, dan senyawa nitrogen non-protein (NPN) lainnya terurai menjadi gas amoniak. Selain merusak lingkungan, gas NH3 dapat mengganggu performa hewan, sehingga rentan terkena penyakit. Penelitian ini bertujuan untuk mengatasi masalah yang berasal dari amonia dengan metode pengukuran dan perancangan alat pengontrol gas amoniak otomatis berbasis arduino menggunakan sensor MQ-135. Jika kadar amoniak di dalam kandang lebih besar dari 5 ppm, kadar amoniak dikendalikan dengan penyemprotan asap cair untuk membatasi emisi gas amoniak. Hasil dari penelitian ini alat tersebut mampu menurunkan kadar gas ammonia hingga 8 ppm.
