Abstract

Infrastructure development of the freight transport system has a vital position in accelerating Indonesian economic growth. This study aims to analyze one of the dominant characteristics of freight transportation, namely freight transportation costs in South Sulawesi Province. A questionnaire-based interview survey of operators was conducted to determine operator characteristics, vehicle characteristics, trip characteristics, and commodity characteristics. They are analyzing data using a descriptive statistical approach, building a cost and distance relationship model using a regression model approach while analyzing the priority of freight transport selection using an Analytical Hierarchy Process (AHP). An AHP is a decision-making model with multiple criteria. The analysis shows that the high costs are the component costs of the operator’s salary, fuel costs, and vehicle maintenance costs. Operating cost modelling provides a good level of models, both in terms of modes and commodities transported. In contrast, the travel time model based on modes and types of commodities shows inefficient. Based on the results, the pickup mode is optimal in cost and travel time with a weight of 39.8% and 50.3%. Trucks 3-4-5 Axles are the optimal mode of transportation when viewed in terms of distance (58.8%) and transportation volume (65.5%). In contrast, the two Axles Truck has characteristics between Pickups and 3-4-5 Axles Trucks. This result is better developed for a more comprehensive model of the cost of freight transport in South Sulawesi Province, Indonesia.

Abstract

Sistem buka tutup pada pintu gerbang konvensional dilakukan secara manual dengan menggeser, membuka atau menutup. Seiring dengan perkembangan teknologi, pintu gerbang dapat dibuka dan ditutup secara otomatis. Pada penelitian ini dirancang sebuah sistem buka tutup pintu gerbang yang dapat dikendalikan menggunakan kode klakson berbasis arduino. Komponen yang digunakan untuk perancangan sistem ini adalah ardiuno nano, sensor suara, motor driver dan motor stepper. Pengujian dilakukan untuk mengetahui jarak maksimum sensor dapat merespon dan mengenali kode klakson yang diberikan. Hasil pengujian menunjukkan bahwa sensor dapat merespon bunyi klakson yang diberi kode khusus 3 bip dengan nilai kode klakson 121 24 106 22 97 pada jarak maksimum 150 cm. Respon sensor terhadap bunyi klakson akan diproses oleh arduino untuk memberikan perintah ke motor driver untuk menggerakkan motor stepper pada pintu gerbang. Sehingga pintu gerbang akan terbuka secara otomatis. Jika kode pada bunyi klakson tidak mencapai nilai dari kode klakson yang telah disimpan maka, pintu gerbang tidak akan bergerak.

Abstract

Penelitian ini dilatar belakangi masalah yang terjadi saat ini adalah faktor produksi rumput laut dipengaruhi oleh faktor suhu dan salinitas air yang harus diperhatikan oleh para petani rumput laut guna sebagai pertimbangan pengambilan keputusan. Tujuan dari penelitian ini adalah untuk untuk merealisasikan sebuah alat yang mampu memberikan notifikasi dan informasi kondisi suhu dan salinitas air pada lahan rumput laut secara realtime. Metode penelitian yang digunakan adalah penelitian kuantitatif deskriptif dengan pendekatan yang dilakukan adalah memonitoring data suhu dan salinitas air pada lahan budidaya rumput laut. Data suhu dan salinitias tersebut kemudian akan dideskripsikan berdasarkan hasil monitoring yang telah dilakukan.. Hasil penelitian menunjukkan bahwa alat yang telah dibuat bekerja dengan baik. Hal ini ditandai dengan presentase kesalahan dari alat yang di buat adalah 0,76%. Pengujian notifikasi menggunakan Aplikasi Blynk pada smartphone dapat berjalan dengan baik selama terhubung dengan koneksi internet. Dengan alat ini, petani dapat memonitoring suhu dan salinitasnya dengan jarak jauh secara real time. Dari hasil pengamatan dan analisis diperoleh bahwa pada bulan September yang berada Kec. Penrang, Kab. Wajo sangat cocok budidaya rumput laut. Hal ini ditandai dengan beberapa kali pengukuran telah menunjukkan hasil bahwa suhu pada ttitik pinggir tambak dan titik tengah tambak berada pada kisaran 26 ℃ s/d 30 ℃. Kondisi salintas pada titik pinggir tambak dan titik tengah tambak masing masing adalah 1100 ppm s/d 1200 PPM.

Abstract

Exhaust emissions from motor vehicles, especially freight transportation, are one of the main causes of air pollution in cities. This research aims to develop a portable and low-cost microcontroller-based vehicle emission measurement system. The system uses Arduino Uno with MQ-7 and MQ-2 sensors to detect carbon monoxide (CO) and hydrocarbons (HC) concentrations in real-time, with the measurement results displayed on the liquid crystal displays (LCD) screen. Validation is carried out by comparing the measurement results of the tool with a calibrated gas analyzer as a standard tool. The test results showed an error rate of 0.29%–1.79% for CO and 1.85%–3.84% for HC, as well as sensor stability after about 360 seconds of heating. With its compact design, easy to operate, and low cost, this system has the potential to be an alternative vehicle emission monitoring tool for field inspection and testing activities at vehicle workshops.

Abstract

Monitoring weather parameters in agricultural fields is essential for improving cultivation efficiency and supporting data-driven decision-making. Farmers often face limited access to real-time microclimate information, highlighting the need for an autonomous and accurate data acquisition system that can operate reliably in the field. This study aims to design and evaluate a sensor-based weather monitoring system that measures temperature, humidity, light intensity, and rainfall conditions, with an emphasis on supporting precision agriculture in rural areas. Field testing was carried out at the Paccoka agricultural site in Watang Suppa Village, where 15 sets of measurements were collected using digital sensors and an RTC module. The results indicate high sensor accuracy, achieving 97.92% for temperature, 94.03% for humidity, and 96.56% for light intensity, while the rain sensor consistently detected surface moisture variations based on incremental water droplets. The developed system demonstrated stable performance and effectively captured real-time microclimate dynamics, making it suitable for implementation as an IoT-based environmental monitoring solution in agricultural applications.

Abstract

The use of solar energy is increasingly important in addressing climate change. This study designed a real-time web-based solar panel performance monitoring system by monitoring voltage, temperature, and light intensity using Arduino Uno and ESP32 connected to Firebase. Testing was conducted for one day from 08.00-17.00 WITA. In the morning at 09.00, Panel 1 reached a maximum voltage of 22.43 V with a light intensity of 54,612.5 lux and a temperature of 38.4 ℃, while Panel 2 reached 21.67 V with an intensity of 54,612.5 lux and a temperature of 39 ℃, Entering the afternoon at 11.30, Panel 2 recorded the highest voltage of 22.82 V at an intensity of 54,612.5 lux and a temperature of 41 ℃, while Panel 1 showed a voltage of 22.6 V with the same light conditions and a temperature of 39.7 ℃. In the afternoon at 5:00 PM, both panels experienced a significant decrease, where Panel 1 dropped to 8.33 V with an intensity of 13,865 lux and a temperature of 28 ℃, while Panel 2 dropped to 8.45 V with an intensity of 10,918.3 lux and a temperature of 28 ℃. It can be concluded that high light is indeed important in producing electrical energy in solar panels but is not enough if it is not balanced with a relatively low temperature. Optimal conditions are achieved when maximum light is accompanied by a temperature that is not too high, with panel 2 showing slightly more stable performance than panel 1.
