Abstract

Pada dasarnya industri pengrajin kasau bambu di pinggiran Kabupaten Malang tepatnya di dusun Krewe Gunungrejo Singosari Malang kurang lebih 75% dari jumlah penduduk 1 RW 303 KK dan 6 RT. Sebelum kemerdekaan silam sudah melakukan usaha kasau bambu, hanya berbekal alat palu, linggis, pahat, kapak, dan arit. Dengan bahan dasar bambu dapat dihasilkan kasau dan gedek.Pada dasarnya masalah yang dihadapi mitra ada dua aspek utama yaitu masalah produksi dan masalah manajemen adalah masalah proses perataan kasau bambu yang kurang bagus dan membutukan waktu yang lama, masih menggunakan sistem pemasaran konvensional yang ditawarkan dari desa ke desa atau door to door, masalah kontrol kualitas produk, kurangnya kontrol kualitas produk yang dapat menjamin kualitas produk, belum dilakukan pembukuan yang tertib, arus kas masih belum jelas, tidak ada neraca bulanan, dan sejenisnya, target luaran dan solusi dari program ini adalah memproduksi usuk bambu dengan kualitas yang lebih baik sehingga pengrajin lebih berkembang dan memiliki segmentasi pasar yang lebih luas, menghasilkan alat penghalus bambu yang dapat digunakan untuk menghaluskan bambu utuh menjadi satu usuk yang halus sehingga pembuatan kasau dari bambu tidak menjadi kendala dalam proses produksi, sehingga terjadi sistem pengelolaan keuangan pada perajin sehingga semua transaksi dapat tercatat dan ternalisa dengan baik.

Abstract

The agricultural sector plays a vital role in national food security; however, land scarcity due to rapid urbanization has encouraged the adoption of alternative methods such as hydroponics. This method enables plant cultivation in controlled environments, yet manual monitoring of key parameters—such as water temperature, pH, and water level—is often inefficient and error-prone. This study presents the development of an automated monitoring and control system based on the Internet of Things (IoT), utilizing a publish/subscribe architecture. The system is built using NodeMCU V3 and Arduino Uno, equipped with temperature, pH, and ultrasonic sensors, and implemented in a Deep Water Culture (DWC) setup. Testing results indicate that the system can accurately read environmental parameters and transmit data in real-time to Firebase, achieving a throughput of 7753 Bps, 0% packet loss, and an average delay of 0.197 seconds from NodeMCU to Firebase, and 2.226 seconds in the reverse direction. The heater, chiller, and water pump operate automatically based on predefined thresholds (±3°C for temperature and +2 cm for water level). All parameters can be remotely monitored and controlled via an Android application. The system has proven to be effective and efficient in supporting precision agriculture and offers a sustainable solution for optimizing hydroponic cultivation in limited land areas.

Abstract

Currently, the construction sector is increasingly developing among the community and business actors. There are various types or types of products on the market provided by concrete mixer manufacturers, such as double shaft mixers which are more efficient for mixing concrete mix so that homogeneity is well maintained. In concrete mixer products currently circulating on the market, there is no monitoring and controlling system for synchronization in the second gear-box rotation, which can prevent fatality damage from occurring. This research aims to create a synchronization monitoring and controlling tool for a double-axis concrete mixer to minimize damage due to use. In the second round, the gear box is corrected to maintain synchronization with the proximity sensor by sending information to the microcontroller which will be displayed on the LCD in the equipment operator's work area and can be accessed outside the operator's work area via a smartphone based on local WiFi network in the company area. If there is a difference in synchronization between the two gear-boxes, the microcontroller will automatically give a command to the relay to turn off the motor driving the two gear-boxes and it can be turned off directly via smartphone.

Abstract

This study investigates the design and implementation of an off-grid solar photovoltaic (PV) system for a meatball cart as a renewable energy solution for small mobile food businesses that still commonly rely on conventional energy sources for lighting and heating. The developed system integrates a 120 Wp monocrystalline PV module, a 12 V 100 Ah LiFePO4 battery, a PWM solar charge controller, a 1000 W inverter, and an automatic soup-heating subsystem based on a DS18B20 temperature sensor, thermocontroller, and solid-state relay. Field testing was conducted on a meatball cart in Pakis District, Malang Regency, for two weeks of operation. The results show that the system was functionally able to operate the supporting loads and maintain soup temperature within 85–95°C through automatic switching control. However, the total daily load of 3810 Wh was still higher than the available daily energy of about 1920 Wh. This finding indicates that the current configuration is feasible as an implementation prototype but has not yet achieved fully autonomous full-load operation. Overall, the study demonstrates the potential of integrating off-grid PV and closed-loop thermal control to reduce dependence on fossil energy and improve the operational flexibility of micro-enterprises.

Abstract

This study aims to analyze the impact of radiator leakage in the main transformer on the power generation performance at the Ampelgading Hydroelectric Power Plant, Malang. Radiator leakage reduces the volume of insulating oil, leading to increased operating temperatures and degradation of insulation quality. A quantitative descriptive method with a case study approach was employed by analyzing temperature data, Breakdown Voltage (BDV), Dissolved Gas Analysis (DGA), and energy production data before and after the disturbance. The results indicate that radiator leakage caused a significant increase in winding and oil temperatures, along with a decline in insulation oil quality marked by elevated dissolved gas levels. Operationally, the disturbance resulted in a power output reduction of 18.27%. Corrective actions, including cold welding, load reduction, and oil purification, were effective in restoring transformer performance, as evidenced by an average BDV value of 68.1 kV categorized as very good, and improved energy production after maintenance. This study concludes that the reliability of the transformer cooling system, particularly the radiator, plays a crucial role in maintaining operational stability and efficiency in hydroelectric power generation.

Abstract

High population mobility requires travel services that are fast, transparent, and able to provide reliable vehicle position information. However, many travel service providers still use manual booking and reporting mechanisms, so customer service, data management, and vehicle monitoring are not yet optimal. This study aims to design and implement a web-based travel booking system integrated with real-time vehicle tracking using Internet of Things technology. The system was developed using the Adaptive Software Development method through the stages of speculation, collaboration, and learning. Vehicle position data were acquired using a Global Positioning System NEO6MV2 module connected to a NodeMCU ESP8266 microcontroller, then transmitted to a server through a web-based application programming interface and displayed on the booking dashboard. System testing showed an average data transmission delay of 1.8 seconds, a data delivery success rate of 98%, and coordinate accuracy within ±3–5 meters. These findings indicate that the proposed system can improve booking data management, accelerate vehicle location monitoring, and increase service transparency for users and administrators. In conclusion, the integration of Internet of Things-based tracking and Adaptive Software Development provides an effective approach for developing adaptive, responsive, and integrated telematics applications for travel service operations.

Abstract

Growing energy demand and the depletion of fossil fuel resources have increased the need for sustainable alternative energy sources. Solar energy is suitable for tropical regions and can be applied to small-scale charging systems. This study designs and implements a temperature monitoring and control system for a solar-powered mobile phone charging box to maintain internal temperature stability and support battery charging performance. The system uses a NodeMCU ESP8266 microcontroller, DHT22 sensor, cooling fan, lighting load, Wi-Fi communication, and Blynk Internet of Things platform for real-time smartphone monitoring. Temperature and humidity data are collected inside the box and transmitted to Blynk, while the fan is activated automatically when the temperature exceeds the predefined threshold. Test results show that the system detected changes in operating conditions. When the fan was off and the lamp was on, the temperature was 28°C with 68.40% humidity. When the fan was on and the lamp was off, the temperature reached 30°C with 78.50% humidity. Solar panel output varied from 19.9 V, 0.393 A, and 7.834 W in the morning to 16.02 V, 0.16 A, and 2.563 W in the afternoon. These findings indicate that the proposed system can support real-time monitoring and automatic thermal control.
