Abstract

Every five years Public Health Research publishes a Public Health Development Index that describes public health in Indonesia. The Public Health Development Index is measured using data from the Public Health Research and the National Socio-Economic Survey, and the Village Potential Survey which is obtained by surveying from sampling data. In fact, the Provincial and City Health Offices have health profile data reports every year. For this reason, this study analyzes existing health profile data using data mining techniques to obtain indicator data that are very influential in formulating the City Health Development Index. This City Health Development Index was successfully formulated by adopting the Model of Public Health Development Index in 2013 and using indicators from annual health profile data which obtained from the data mining process, i.e., Random Forest algorithm. The proposed model can be used as the annual report of a city to describe the health condition of that city. For the future research, the model can be adopted to measure some specific aspects of city health condition.

Abstract

Pasangan laki-laki dan perempuan yang telah terikat dalam suatu perkawinan secara sah secara hukum agama maupun negara tentunya berharap mempunyai keturunan yang kelak akan melanjutkan garis keturunan mereka dan kelangsungan hidup umat manusia di dunia. Akan tetapi tidak semua pasangan suami isteri dapat mempunyai keturunan secara cepat bahkan didiagnosa tidak bisa mempunyai keturunan dikarenakan berbagai faktor medis maupun hal yang lain. Perkembangan teknologi pada bidang kedokteran khusunya reproduksi memungkinkan pasangan suami isteri yang mengalami ketidaksuburan ini untuk memiliki keturunan dengan menjalani program bayi tabung ataupun inseminasi buatan. Kedua teknologi ini melakukan pembuahan sel telur dengan sel sperma tidak secara alamiah. Hal ini menimbulkan pro dan kontra dilihat dari sudut pandang agama Islam. Penjelasan dan pertimbangan yang dikeluarkan dari MUI, NU, dan Muhammadiyah memperbolehkan bayi tabung dan inseminasi buatan secara Hukum Agama Islam tapi dengan syarat sel sperma dan sel telur berasal dari suami isteri yang sah dan sel telur yang telah dibuahi dititipkan pada rahim asal sel telur bukan isteri lain dari suami jika berpoligami.

Abstract

Solar modules are essential components of a solar power plant, that are designed to withstand scorching heat, storms, strong winds, and other natural influences. However, continuous usage can cause defects in solar modules, preventing them from producing electrical energy optimally. This paper proposes the development of a deep learning-based system for identifying and classifying solar module surface defects in solar power plants. Module surface condition are classified into five categories: clean, dirt, burn, crack, and snail track. The dataset used consists of 8,370 images, including primary image data acquired directly from the mini solar power plant at the Renewable Energy Laboratory of PLN Institute of Technology, and secondary image data obtained from public repositories. The limitation in the number of images in each category was overcome using data augmentation techniques. The proposed classification model combines Deep Convolutional Neural Networks (DCNN) with transfer learning models (DenseNet201, MobileNetV2, and EfficientNetB0) to perform supervised image classification. Training and testing results on the three models demonstrated that the combination of DCNN + DenseNet201 provided the best performance, with a classification accuracy of 97.85%, compared to 97.25% accuracy for DCNN + EfficientNetB0 and 94.98% for DCNN + MobileNetV2. This research shows that DCNN-based image classification reliably diagnoses solar module defects and supports using RGB images for surface defect classification. Applying the developed system to solar power plant maintenance management can help in accelerating the process of identifying panel defects, determining defect types, and performing panel maintenance or repairs, while ensuring optimal power production.
