Abstract

Sungai telah menjadi bagian yang penting bagi masyarakat di Indonesia. Namun kondisi sungai pada saat ini banyak yang tercemar dan mengalami pendangkalan. Pendangkalan diakibatkan oleh sedimentasi. Pertambahan sedimentasi dapat dilihat dari perubahan bentuk kontur tanah dan peningkatan volume tanah didalam air. Perubahan bentuk kontur tanah dapat dideteksi dengan menggunakan sensor ultrasonik. Sensor ultrasonik dapat mendeteksi keberadaan benda/objek didalam air. Pada prinsipnya, sensor ultrasonik bekerja menggunakan pantulan gelombang dari suatu benda/objek didepannya. Dalam hal ini, sensor ultrasonik ditempatkan sedikit masuk kedalam air dan lapisan tanah didalam air dapat dideteksi sebagai suatu benda/objek. Parameter yang akan diukur yaitu jarak deteksi yang dilakukan secara horizontal dan vertikal. Data hasil pengukuran seluruhnya akan ditabulasi dan dibuat dalam bentuk grafik 3D menggunakan matlab sehingga akan terbentuk seperti bentuk kontur tanah yang mendekati bentuk kontur tanah sebenarnya

Abstract

Pembangunan waduk dapat mendorong pemerataan ekonomi dan kesejahteraan, meningkatkan kedaulatan pangan serta untuk pengendalian banjir. Namun banyak waduk yang jebol di Indonesia disebabkan oleh wadah penampung (dead storage) waduk yang semakin kecil akibat dari sedimentasi sehingga naiknya permukaan air waduk dan keluar dari jalur tumpahannya (spillway). Pentingnya dilakukan monitoring terhadap naiknya permukaan air sebagai tindakan pertama untuk pencegahan bencana jebolnya tanggul waduk. Pendeteksian ketinggian air dapat menggunakan sensor ultrasonik. Dalam hal ini, sensor ultrasonik ditempatkan diatas permukaan air. Parameter yang diukur yaitu jarak deteksi terhadap permukaan air secara vertikal. Berdasarkan hasil pengukuran, sensor ultrasonik JSN-SR04T dapat mengukur sampai diatas 200 cm terhadap permukaan air. Pengukuran dilakukan sebanyak 10 kali dengan hasil rata-rata error rate 3,21%. Pembacaan data dilakukan dalam 5 level ketinggian air. Digunakan logika fuzzy untuk menentukan klasifikasi ketinggian permukaan air. Berdasarkan hasil penelitian, jarak deteksi rata-rata 209,14 cm α-predikat 1 status “Air rendah”, jarak deteksi rata-rata 181,17 cm α-predikat 0,2 status “Air rendah”, jarak deteksi rata-rata 154,83 cm α-predikat 0,2 status “Air agak rendah”, jarak deteksi rata-rata 128,05 cm α-predikat 0,2 status “Air sedang”, jarak deteksi rata-rata 102,29 cm α-predikat 0,2 status “Air tinggi”.

Abstract

The goods delivery service industry has emerged as a strategic business both during and after the pandemic. The shift towards online shopping, which became a norm during the pandemic, let’s continue post-pandemic, making it a promising sector for companies involved in goods delivery. However, the industry faces challenges, particularly related to security during shipment. One common issue is the inability to track vehicle positions, leading to unauthorized loading and unloading activities at incorrect locations, causing losses for business owners. Conventional mechanical locks are vulnerable to theft, duplication, key loss, and vandalism, making them inadequate for securing cargo. To address these issues, Smart Lock technology has been developed, offering enhanced security through modern, integrated features. This technology eliminates the need for physical keys, reducing the risk of loss, and allows for remote access management. Additionally, it enables cargo owners to monitor the vehicle's position and control the lock remotely. Given these advancements, there is a need to explore Tracking Systems for delivery vehicles, incorporating automatic locks controlled via Internet of Things (IoT) technology. Based on the measurement, the tracking system tool testing was carried out at 5 different locations. The distances are 2.9 km, 6.4 km, 3 km, 7.1 km, 4.7 km from campus. The GPS signal is sent to the cloud server Cloud of Jointech. Data transmission uses the GSM network. There is a delay difference of 2-3 seconds from the GPS time signal compared to the time data displayed on the website. The data provided from the GPS signal is updated every 20 seconds. Based on the 5 test locations that have been set, the on/off lock test has been successfully carried out.

Abstract

The demand for vegetables in Batubara Regency is extremely high. Currently, the supply of vegetables is still imported from Tanah Karo and Deli Serdang Regency. This is due to the geographical condition of Batubara Regency which is in a coastal area. The majority of their people work in the fisheries sector. This opportunity was taken by our partner from SMK T. Amir Hamzah Indrapura by building greenhouse to produce vegetables. However, there are obstacles, namely the partner does not have a cheap source of electricity to increase the production of hydroponic vegetables. Therefore, it is necessary to build an alternative electricity source in the form of a solar power plant. It saves monthly electricity costs at the greenhouse. An environmental monitoring system needs to be built at the greenhouse to maintain and monitor the parameters that affect the growth requirements of hydroponic vegetables such as temperature, humidity, and lighting.
