Abstract

Makanan pokok kaya akan karbohidaran dan dapat digunakan untuk berbagai macam olahan salah satunya adalah jagung. Produksi jagung yang meningkat juga akan berdampak pula terhadap peningkatan pendapatan atau ekonomi masyarakat di Indonesia. Akan tetapi sebagian besar produksi jagung sering mengalami kerusakan dan perlu diperbaiki ketika dipanen khususnya pada waktu musim hujan. Hal inilah yang dapat membuat petani jagung mengalami kegagalan dan penurunan kualitas jagung pada waktu masa panen. Agar petani jagung dapat menilai hasil atau kualitas pertanian jagungnya yang sesuai dengan Standar Nasional Indonesia (SNI), maka diperlukan sebuah sistem pakar untuk menentukan kualitas jagung menggunakan metode Naïve Bayes. Hasil penelitian menunjukkan bahwa penentuan kualitas jagung menggunakan metode Naïve Bayes tergolong sangat baik. Nilai persentase hasil akurasi sebesar 90% pada data testing sebanyak 30 dan data training sebanyak 60. Nilai hasil akurasi sebesar 94% pada data testing sebesar 90 dan 120, data training 100 dan 150. Hal ini menunjukkan bahwa metode Naïve Bayes dapat digunakan dalam menentukan kualitas jagung.

Abstract

Tobacco is a plantation commodity that is susceptible to pests and diseases, such as Phytophthora nicotianae (lanas disease), Myzus persicae (aphids), or Cercospora nicotianae (leaf spots). Lack of farmer knowledge in identifying early symptoms often leads to inappropriate handling and economic losses. This study aims to develop an expert system based on the Forward Chaining method to diagnose tobacco plant pests and diseases quickly and accurately. Symptom data are collected through field observations and literature and then represented as rule-based knowledge (for example, "IF leaves with yellow spots AND brown spots in the middle THEN Cercospora nicotianae"). The Forward Chaining method makes inferences by matching user input facts (symptoms) to existing rules to reach conclusions. The system was tested using 50 field cases with an accuracy of 85% compared to manual diagnosis by experts.

Abstract

In this study, Unisla's solar electric vehicles uses five 100Wp solar panels assembled in series so that it has a total power of 500Wp. The design of this solar cell power monitoring system uses ESP32 as a microcontroller with the concept of Internet of Things (IoT) so that the device can be connected to the internet in real-time. The sensors used to read the current and voltage flowing from the solar panel are the ACS712 sensor and the voltage sensor is a voltage divider circuit made from resistors with R1 66100 Ohm and R2 3200 Ohm values respectively. Of the 10 test samples, the average error value of the voltage sensor used had a fairly good accuracy, with an average error of only 0.301%. This shows that the measurement difference between the sensor and the multimeter is relatively small. Meanwhile, the measurement difference between the ACS712 sensor and the power supply is very small, ranging from 0.01 to 0.02 Amperes with an average error of 0.01%. This shows that the measurement deviation of the ACS712 sensor compared to the reference value is very small, making it reliable for current measurement applications. The power monitoring tool developed was successfully implemented on Unisla Solar Electric Vehicles in real-time. Tests show that the appliance can read the voltage, current, and power generated by 5 solar panels assembled in series with a total power of 500Wp. The highest rated voltage data is 73.12Volts at 14.00, while the lowest data is 65.22Volts at 17.00, the rated highest rated current is 7.11A at 12.00, while the lowest current is 1.10A at 17.00, the highest rated power is 505.65Watt at 13.00, while the lowest power is 71.74 Watts.

Abstract

Water is one of the primary needs essential for all living beings. In daily life, water is not only used for drinking but also for bathing, washing clothes, irrigating agricultural fields, and various other activities. However, current water resources, both in terms of quantity and quality, are increasingly unable to meet rising demands. The quality of water for daily use has also deteriorated significantly. The increasing annual demand for water is driven by population growth and the fact that almost every human activity requires water. The diversity of human activities has led to rising water pollution, which is one of the major factors contributing to the decline in the availability of clean water. To address this, a device capable of monitoring water quality is proposed. This tool is equipped with turbidity sensors, DS18B20 temperature sensors, and pH sensors, all controlled by an ESP 32 microcontroller and connected via the Internet of Things (IoT). Through this system, real-time water quality monitoring becomes feasible, enabling more optimal and efficient water utilization.

Abstract

Informasi ilmiah berkaitan dengan spesies invasif di Indonesia masih sangat minim terutama mengenai mikroalga. Kajian ini dilakukan pada bulan September – November 2023 di tiga pelabuhan Provinsi Aceh dengan tujuan untuk menganalisa faktor kualitas air, mengidentifikasi jenis mikroalga dan menduga ada tidaknya mikroalga invasif. Data mikroalga dikumpulkan dengan menyaring sampel air permukaan. Parameter suhu, pH, salinitas, kecepatan arus, kecerahan dan oksigen terlarut diukur secara in situ, sedangkan fosfat, nitrat dan ammonia diukur secara ex situ; serta karakteristik kualitas perairannya dianalisis dengan PCA. Sementara untuk menduga ada atau tidak adanya mikroalga invasif dilakukan dengan membandingkan hasil penelitian mikroalga para ahli lain di sekitar lokasi penelitian. Nilai fosfat, nitrat dan ammonia sudah melebihi baku mutu (1.07 ± 1.00 mg/L, 1.63 ± 0.95 mg/L, 0.47 ± 0.74 mg/L) yang mengindikasikan adanya peningkatan produksi mikroalga, kemudian komposisi mikroalganya ditemukan sebanyak 407 ind/ml, 21 spesies dan 5 kelas. Selanjutnya karakteristik kualitas perairannya menunjukkan adanya tiga pengelompokkan hasil dari analisis PCA dengan hasil identifikasi tidak menemukan spesies mikroalga invasif.  Scientific information relating to invasive species in Indonesia is still very minimal, especially regarding microalgae. This study was carried out in September – November 2023 at three ports in Aceh Province with the aim of analyzing water quality factors, identifying types of microalgae, and suspecting the presence or absence of invasive microalgae. Microalgae data was collected by filtering surface water samples. The parameters temperature, pH, salinity, current speed, transparency, and dissolved oxygen were measured in situ, while phosphate, nitrate, and ammonia were measured ex situ, and the water quality characteristics were analyzed using PCA. Meanwhile, to suspect the presence or absence of invasive microalgae, this is done by comparing the results of microalgae research from other experts around the research location. The values of phosphate, nitrate, and ammonia have exceeded the quality standards (1.07 ± 1.00 mg/L, 1.63 ± 0.95 mg/L, and 0.47 ± 0.74 mg/L), which indicates an increase in microalgae production. The microalgae composition was found to be 407 ind/ml, 21 species, and 5 classes. Furthermore, the water quality characteristics show that there are three groupings resulting from PCA analysis, with the identification results not finding invasive microalgae species.
