Tujuan dari pembuatan strata ketika pengambilan contoh dalam survei adalah untuk menghasilkan penduga paremeter dengan varians kecil, sehinggapenentuan alokasi strata perlu diperoleh. Menentukanbanyaknya strata dan alokasi elemen strata dari suatu himpunan nilai respon akan menjadi fokus dari penelitian ini. Algoritma Genetik (AG) diaplikasikan untuk kasus ini dengan meminimalkan varians dalam strata pada himpunan yang tersedia, dari jumlah strata 2 sampai 6 strata. Studi empiris melalui simulasi dikembangkan dalam skema populasi yang telah diketahui banyaknya strata sebenarnya, kemudian dengan beberapa jenis banyaknya strata, AG diterapkan dalam data. Berdasarkan hasil simulasi, dapat disimpulkan bahwa AG dapat memberikan banyaknya strata yang sesuai dengan banyaknya strata sebenarnya, sehingga dapat menjadi metode alternatif yang baik untuk memilih banyaknya strata optimal dalam pengambilan contoh survei.

The growth of children under the age of three (toddlers) is one of the determinants of children's development in the future. One of the parameters of toddler growth assessment is determined by gender, age, height and weight. This research makes a system that can monitor toddler growth with web-based. The research method used is the System Life Development Cycle, which consists of planning, analysis, design, implementation and use. This system also uses the Tsukamoto fuzzy method to determine the membership set of each input variable. The gender criteria are divided into two classes, male and female, the age criteria are divided into three classes, the height criteria are three classes, and the weight criteria are divided into three classes. Based on the division of classes, the output of this study is the growth status of toddlers, namely poor growth, poor, normal and more. Based on the results of input data criteria and calculations using Tsukamoto fuzzy, the output obtained in the form of the status of the child's growth.

Provinsi DKI Jakarta memiliki kepadatan penduduk terbesar di Indonesia yang riskan dengan permasalahan lingkungan, salah satunya di sungai-sungainya. Sekitar 52.5% desa/kelurahan yang dilalui sungai memiliki kondisi sungai tercemar limbah. Penelitian ini bertujuan untuk melakukan eksplorasi kondisi sungai tercemar limbah yang disertai dengan identifikasi faktor-faktor yang diduga memengaruhinya berdasarkan data Potensi Desa (Podes) tahun 2018 (Badan Pusat Statistik, 2018). Eksplorasi data dilakukan dengan membuat plot tebaran dan ringkasan statistik, dengan hasil yang diperoleh adalah mayoritas sumber limbah berasal dari limbah rumah tangga. Selanjutnya, analisis regresi logistik beserta metode stepwise dilakukan untuk mengidentifikasi faktor-faktor dari segi kondisi lingkungan, alih fungsi, serta kondisi sosial ekonomi desa/kelurahan yang memengaruhi kondisi sungai tercemar limbah. Hasilnya, faktor yang memengaruhi sungai tercemar limbah meliputi adanya fungsi alih sungai dan banyaknya rumah tangga miskin dengan kategori tinggi. Selain itu, faktor adanya perawatan sungai dapat digunakan sebagai indikator bahwa sungai di desa/kelurahan di DKI Jakarta tercemar limbah.

Digital information media in this era has very good potential, especially in developing micro-businesses to introduce their products, besides that information media is also needed to provide education and information to socialize, this is very necessary for the government in the district to develop village results and information that can be conveyed clearly to the community. Community service carried out by the Computer Science Study Program of Pakuan University aims to provide training to village office staff and junior and senior high school students in Bantarsari Village to be able to apply Canva as a medium for promoting micro-business and related information media, socialization, disaster prevention, appeals and other notifications in Bantarsari Village

Pneumonia is an infection of the respiratory tract caused by bacteria, viruses, or fungi. The number of pneumonia cases in West Java is relatively high, therefore, it is necessary to identify some group of regencies/cities in which have a common characteristic, to make it easier to handle. The data used is data on the number of pneumonia cases in 27 regencies/cities in West Java in 2020. In this study, chi-squared test was applied to determine the characteristics of pneumonia spread in West Java. Then, a regression-based analysis by using the Irregular Graph Fused LASSO method was used to provide the cluster of regencies/cities, by considering the adjacent locations of regencies/cities as a penalty matrix. The results obtained that the cases spread unevenly. The number of cases for every 1000 people in each regency/city was relatively high in the eastern part of West Java. There were 6 clusters obtained from 27 regencies/cities, with Pangandaran regency as the location with the highest cases occurred. Depok City and Bekasi City were locations with the lowest number of cases even though they have relatively high population numbers.

Electric vehicles (EVs) are widely recognized as an environmentally sustainable alternative capable of reducinggreenhouse gas emissions; however, their adoption in Indonesia remains limited. Data from the IndonesianMinistry of Transportation, as recorded in the Type Approval Registration System (SRUT), indicate thatapproximately 195,084 Battery Electric Vehicles (BEVs) were registered nationwide by early 2024. This studyinvestigates public sentiment toward electric vehicles using social media data from X, Instagram, and TikTok,while also comparing the effectiveness of two text classification approaches: Bidirectional EncoderRepresentations from Transformers (BERT) and Long Short-Term Memory (LSTM). A total of 5,172Indonesian-language comments were collected through crawling and scraping techniques using electricvehicle-related keywords over the period January 2021 to January 2025. The comments were categorized intofive sentiment classes: very positive, positive, neutral, negative, and very negative. The analytical processfollowed the Knowledge Discovery in Databases (KDD) framework, including data preprocessing,transformation, classification, and evaluation using a confusion matrix. The results indicate that IndoBERTsubstantially outperformed LSTM, achieving an accuracy of 91% compared to 36% for LSTM. Sentimentanalysis reveals a dominance of negative and very negative opinions, primarily reflecting public concernsregarding cost, performance, and maintenance of electric vehicles. These findings offer important insights forpolicymakers and the automotive industry in designing targeted promotion strategies, improving publicawareness, and strengthening supporting infrastructure. Future research is encouraged to explore dataaugmentation techniques to improve model performance, particularly for deep learning models such as LSTM,in order to better support evidence-based electric vehicle adoption policies.
