DIAGNOSING ANDROID-BASED VIRUS INFECTIONS IN CHILDREN USING NAIVE BAYES

KH, Musliadi, Kaharuddin, Kaharuddin, Syafrinal, Ilwan
Abstract: Abstract: Infectious diseases are one of the most common health problems in children because they have immature immune systems. Children are more susceptible to infections caused by bacteria, viruses, fungi, and protozoa.… . Some common infectious diseases in children include fever, acute respiratory infections (ARI), pneumonia, acute gastroenteritis (GAE), measles, chickenpox, and diphtheria. The limited number of pediatricians and the difficulty of accessing health facilities in remote areas hinder children's health services. To overcome this, an Android-based expert system is needed using the Naïve Bayes method to help diagnose infectious diseases in children earlier. The research method used is the Software Development Life Cycle (SDLC), where Black Box is used for internal testing, and PSSUQ is used to measure user satisfaction. The data set used was 1320 taken from a local hospital. The test results show that all the main features work as expected without any errors. The implementation of the system in diagnosing diseases went well and based on end-user feedback from 74 respondents, the system obtained a user satisfaction score of 6.40, where users felt that the system was easy to use, efficient, and provided clear and useful information.   Keywords: expert system; infectious disease; naïve bayes; PSSUQ; SDLC     Abstrak: Penyakit menular merupakan salah satu masalah kesehatan yang paling umum terjadi pada anak-anak karena mereka memiliki sistem kekebalan tubuh yang belum matang. Anak-anak lebih rentan terhadap infeksi yang disebabkan oleh bakteri, virus, jamur, dan protozoa. Beberapa penyakit infeksi yang umum terjadi pada anak-anak antara lain demam, infeksi saluran pernapasan akut (ISPA), pneumonia, gastroenteritis akut (GEA), campak, cacar air, dan difteri.

THE USE OF IOT IN WATER UTILIZATION STRATEGIES FOR SMART IRRIGATION SYSTEMS BASED ON MACHINE LEARNING

Junaidi, Junaidi
Abstract: Abstract: Water irrigation is a crucial aspect of agriculture that often becomes the primary concern for farmers, especially because suboptimal management can lead to decreased crop yields and reduced income. So far, farmers… mers have been practicing irrigation manually, where plants are watered twice a day, in the morning and evening, based on weather conditions without considering soil temperature or moisture levels. Based on the observations conducted, it was found that excessive water application increases water accumulation, resulting in nutrient loss from the soil and even root diseases. The objective of this study is to develop a system utilizing an ESP32 microcontroller and sensors to detect soil moisture, with a machine learning-based K-Nearest Neighbor (KNN) model, enabling farmers to remotely monitor and control their crops using an Android device. The testing results showed that with input data of 32°C temperature, 40% soil moisture, and 60% air humidity, the system produced a nearest distance of 0.000 and 0.541 from the closest k-nearest neighbors, with a status label of "needs water." As a result, the relay activates the water pump to irrigate the field. Meanwhile, for data with a nearest distance of 0.897, the system identified the status as "does not need water," indicating that the soil remains wet or moist. This study is expected to help reduce farmers' workloads by optimizing water usage according to plant needs and improving crop quality and yield.         Keywords: k-nearest neighbor (KNN); mikrokontroller ESP32; machine learning; water irrigation   Abstrak: Irigasi air merupakan aspek penting dalam pertanian yang menjadi perhatian utama petani, terutama karena pengelolaan yang kurang optimal berdampak pada penurunan hasil panen dan pendapatan. Selama ini, praktik irigasi oleh petani dilakukan secara manual, di mana penyiraman tanaman dilakukan dua kali sehari pada pagi dan sore berdasarkan kondisi cuaca tanpa memperhatikan suhu atau kelembaban tanah. Berdasarkan hasil observasi yang dilakukan, ditemukan masalah yaitu pemberian air secara berlebih menyebabkan akumulasi air meningkat mengakibatkan kehilangan nutrisi tanah dan bahkan penyakit akar. Tujuan penelitian ini menciptakan sistem yang dirancang menggunakan mikrokontroler ESP32 dan sensor untuk mendeteksi kelembaban tanah, dengan model K-Nearest Neighbor (KNN) berbasis machine learning sehingga memudahkan petani untuk mengontrol tanaman mereka dari jarak jauh menggunakan android. Hasil pengujian yang dilakukan dengan data inputan berupa suhu 32°C, kelembaban tanah 40% dan kelembaban udara 60%, sistem menghasilkan jarak terdekat sebesar 0.000 dan 0.541 dari k-nearest terdekat dengan label status "butuh air". Maka relay akan mengaktifkan pompa air untuk mengairi lahan. Kemudian, pada data dengan jarak terdekat 0.897, sistem mengidentifikasi status "tidak butuh air", menunjukkan bahwa kondisi tanah masih basah atau lembab. Penelitian ini diharapkan dapat membantu meringankan beban kerja petani mengoptimalkan penggunaan air sesuai dengan kebutuhan tanaman dan meningkatkan kualitas hasil panen.

Implementation of Labor Law in the Era of Industrial Revolution 4.0 - Challenges and Solutions

Bachrul Amiq, Wahyu Prawesthi, Noenik Soekorini, Hartoyo Hartoyo, Sri Astutik
Abstract: The Industrial Revolution 4.0 has drastically transformed global industries, introducing advanced technologies such as automation, artificial intelligence, and digitalization into the workplace. This rapid technological… shift has presented significant challenges for labor laws, which are often designed for traditional work environments. This study explores the implementation of labor law in the context of the Industrial Revolution 4.0, analyzing the challenges faced by both employers and employees in adapting to these new technological advancements. Using a qualitative methodology, this research employs a juridical review of existing labor laws, supported by an in-depth case study examining how these laws are applied in technology-driven industries. The findings indicate that labor laws often lag behind the technological advances, leading to gaps in legal protections for workers and ambiguities in employer obligations. The case study highlights specific instances where current labor regulations fail to address issues related to remote work, job displacement due to automation, and workers' rights in the gig economy. Solutions are proposed to modernize labor laws, ensuring they are adaptable to future technological developments while safeguarding workers' rights. The study concludes that there is an urgent need for legal reforms to balance innovation with fair labor practices in the era of Industry 4.0.
