Abstract

This research aims to develop a monitoring and control system for catfish pond water quality based on the Internet of Things (IoT). This system uses an ESP32 microcontroller Arduino Integrated Development Environment (IDE) connected to a SEN0131 pH sensor, DS18B20 temperature sensor, and HC-SR04 ultrasonic sensor to monitor water quality parameters such as pH, temperature, and water level. Data obtained from these sensors is stored in a real-time database that can be accessed remotely via the Blynk application. This system is also equipped with a water pump and solenoid valve that automatically controls water filling and discharge based on detected water quality parameters. The test results show that the system has an average accuracy of 99.45% and high precision with an average relative standard deviation of 0.01% in detecting water quality parameters. System operation was carried out for 27 days. The system can run continuously or non-stop. data is input in real-time to blynk, so it can be monitored and controlled from anywhere.

Abstract

Soil fertility parameters, including macronutrients, micronutrients, and metal content, are very important for optimizing agricultural and plantation land management. Ultisol is a type of soil that is commonly used as a planting medium for oil palm plantations, rubber, and various types of vegetables. Continuous land use causes variations in nutrient and metal content. This change is also caused by the fertilization process and the characteristics of the plants grown in the area. In this study, an analysis of soil fertility parameters (macronutrients, micronutrients, and metal content) was analyzed using X-Ray Fluorescence (XRF) on Ultisol soil taken from Muara Jambi Regency, Indonesia. This analysis was conducted across land-use areas (Palm, Rubber, Vegetables, and Forest). Subsequently, the obtained measurements were used to model correlations with soil pH values to predict soil fertility parameters. The quantitative results showed that the metal content values were reasonably consistent across all locations regarding metal types and their percentage concentrations. However, locations 1 (T1) and 2 (T2) have higher aluminum (Al) content than locations 3 and 4 and lower magnesium (Mg) content. The modeling, when correlated with pH values, indicated that metal elements correlated 0.938, macronutrients 0.934, and micronutrients 0.767. From these correlations, it can be qualitatively inferred that there is a strong relationship between pH and the presence of metal content, macronutrients, and micronutrients. In the future, this can serve as a model for estimating the presence of soil fertility parameters.

Abstract

Fisika merupakan salah satu mata pelajaran yang berkaitan erat dengan kehidupan sehari-hari. Namun siswa sering mengalami pemahaman konsep yang berbeda dengan para fisikawan. Perbedaan pemahaman tersebut dapat memicu terjadi miskonsepsi, sehingga diperlukan upaya dan instrumen untuk mengukur miskonsepsi siswa yang biasa disebut tes diagnostik, salah satu diantaranya adalah berbentuk three  tier multiple choice. Penelitian ini bertujuan untuk mengetahui tingkat miskonsepsi peserta didik pada materi hukum Newton di kelas X ipa SMA Negeri 15 OKU. Dengan menggunakan rancangan Borg and Gall tujuh tahapan. Subjek penelitian sebanyak 34 siswa kelas X IPA SMA Negeri 15 OKU. Reliabilitas soal yang dikembangkan sangat tinggi, artinya soal tes reliabel. Produk akhir terdiri dari 2 soal kategori mudah, 10 soal kategori sedang dan 4 soal kategori sukar. Soal tes memiliki tingkatanyang berbeda: 4 soal sukar, 12 soal sedang dan mudah 12% siswa yang mengalami miskonsepsi yang termasuk dalam kategori rendah, dengan miskonsepsi (false positive) sebesar 2.5%, miskonsepsi (false Negative) sebesar 3.1% dan Miskonsepsi 6.4% dengan miskonsepsi tertinggi terdapat pada soal nomor 4 sebanyak 11 siswa. Hasil uji validitas oleh tiga validator ahli menunjukkan validitas yang tinggi dengan rata-rata 4,45 dengan kriteria valid dari tiga ahli validasi. Setelah melakukan semua rangkaian tahapan penelitian adapun hasil dari penelitian ini mengidentifikasi miskonsepsi pada materi hukum Newton pada kelas X di SMA N 15 OKU sebesar 12% dalam kategori miskonsepsi rendah. Dengan adanya penelitian ini guru dapat mendiagnosis miskonsepsi yang dialami peserta didik lebih mendalam, menentukan materi yang memerlukan penekanan lebih saat pembelajaran, dan merencanakan pelajaran yang lebih baik untuk membantu mengurangi miskonsepsi peserta didik.

Abstract

Pengabdian kepada masyarakat yang diselenggrakan oleh tim dosen Program Studi Fisika, Universitas Jambi bertujuan untuk meningkatkan softskills mahasiswa semester satu yang ada di Program Studi Fisika untuk dapat bersaing di era revolusi industry 4.0 dan society 5.0. Sasaran kegiatan pengabdian masyarakat yaitu seluruh mahasiswa semester satu angkatan 2022 di Program Studi Fisika yang berjumlah 29 orang. Kegiatan dilaksanakan dalam bentuk webinar yang berlangsung pada tanggal 15 Oktober 2022. Metode kegiatan berupa penyampaian materi oleh tim dosen Program Studi Fisika dan pendampingan dalam bentuk diskusi kelompok di kelas, dan evaluasi. Hasil dari kegiatan pengabdian masyarakat ini yaitu dapat meningkatkan pemahaman mahasiswa tentang jenis-jenis softskills yang harus dikuasai untuk hidup di era revolusi industry 4.0 dan society 5.0 dan dapat mempraktikkan softskills dalam bentuk diskusi kelompok di kelas. Kemudian berdasarkan hasil evaluasi dalam bentuk kuisioner menunjukkan bahwa terdapat 39,6% mahasiswa mempunyai softskills dengan kategori sangat baik, 40,9% mahasiswa mempunyai softskills dengan kategori baik, 17,5% mahasiswa mempunyai softskills dengan kategori cukup, dan 1,9 mahasiswa mempunyai softskills dengan kategori kurang.

Abstract

Arduino uno microcontroller is an open source based integrated circuit device that can be easily obtained, relatively cheap, accessible, and low power consumption. It can be applied to design practicum kits related to electronics and electricity. Our community service activity was holding a workshop on making practicum kits based on the Arduino Uno microcontroller for teachers at SMK Negeri 9 Muaro Jambi. The program was carried out through three stages, firstly, observation and survey, next was planning and preparation, and the last one was training. The themes of the chosen practicum kits were the LED turning-on program, distance measuring program, fire detection program, and temperature and humidity measurement. Each of the kits was equipped with the sets needed for practicum, such as Arduino Uno, jumper cables, LEDs, breadboard/protoboard, resistors, USB cables, sensors, etc. The practicum guide book contained the objectives of the practicum, tools and materials used, programming language commands to be uploaded, as well as work steps and evaluations. Workshop was carried out by a lecture about arduino uno microcontroller and demonstration of how to operate practicum kits. During the demonstration activity, the teachers were enthusiastically discussed and asked questions about Arduino Uno microcontroller as a practicum kit.

Abstract

Penyakit tuberkulosis disebabkan oleh bakteri Mycobacterium tuberculosis yang menyerang organ tubuh manusia. Tujuan dari penelitian ini adalah untuk menemukan senyawa dari tanaman Eukaliptus lemon, yaitu Linalool, Isopulegol, Farnesan, dan Citronellol yang paling berpotensi sebagai obat tuberculosis melalui metode molecular docking. Pada penelitian ini digunakan 2 jenis protein yaitu 4KM2 dan 4KL9 yang ditambatkan dengan senyawa Eukaliptus lemon. Hasil docking dievaluasi berdasarkan parameter dari nilai konstanta inhibisi (ki) dan nilai energi afinitas (ΔG). Senyawa Farnesan menunjukkan hasil terbaik dengan energi afinitas (ΔG) terendah, yaitu 5,3 kcal/mol, dan ki sebesar 0,9144 µM. Hasil ini menunjukan Farnesan memiliki potensi sebagai kandidat resistensi obat untuk menyembuhkan penyakit tuberculosis.
