K-Means Clustering for Determining Quality of Outdoor Temperature Based on BMKG Datasets: K-Means Clustering

The purpose of this study was to determine the quality of outdoor temperatures that are good for conducting activities. One of the factors that cause the body's healthy or not human temperature, either indoors or outdoors. The data used is the BMKG weather dataset. BMKG weather dataset is a type of quantitative data because it is numeric or nominal and can be calculated. At each day, BMKG also provides information about the temperature according to the state of each area. It is starting from the minimum temperature, maximum, average humidity, to the maximum wind speed. The method used is clustering using the k-means clustering with centroid value. This research resulted in outdoor temperature clustering, which is good, INTERMEDIATE, and bad quality. In the range of values 124.7 indicate good temperature, range values 133.1 indicate moderate temperature, range of values 146.8 indicate bad temperature. Based on research in 32 days produced 28 days of moderate temperature quality, two days of good temperature quality, and two days of poor quality

Perancangan, Pembuatan dan Instalasi Pompa Hidram di Desa Cikiray Kabupaten Sukabumi

ABSTRAKDesa Cikiray memiliki potensi sumber air yang sangat besar karena desa ini berbatasan langsung dengan Taman Nasional Gunung Halimun di sebelah utara sehingga sumber mata airnya sangat terjaga. Ironisnya, potensi air yang melimpah ini belum bisa termanfaatkan oleh warga desa secara maksimal. Bahkan warga desa yang tinggal di perbukitan mengalami keulitan mendapatkan air bersih, terutama untuk keperluan air minum dan memasak. Pemasangan pompa air listrik tidak mungkin dilakukan karena jarak yang jauh dari sumber listrik. Salah satu solusi yang dapat dilakukan untuk membantu warga desa Cikiray memecahkan masalah ini adalah dengan memasang pompa hidram yang dapat dioperasikan tanpa tenaga listrik. Pompa hidram yang dipasang di desa Cikiray memberikan kinerja yang cukup memuaskan walaupun belum mencapai target yang diinginkan. Setidaknya 72% dari kebutuhan air minum warga di 2 RW di desa Cikiray sudah dapat terpenuhi dengan adanya instalasi pompa hirdram ini.Kata kunci: pompa hidram, air bersih, desa CikirayABSTRACTCikiray village has a very large potential for water resources because this village is directly adjacent to the Mout Halimum National Park that the springs are very well presrved. Ironically, this abundanr water potential has not been fully utilized by the villagers. Even villagers in hilly areas have difficulty getting clean water, especially for dringking and cooking purpose. Installation of an electric pump is not possible due to the long distance from the electrical power source. Solution that can be done to help the villagers is to install a hydraulic ram pump that can be operaqted without electricity. The hydraulic ram pump that installaed in the Cikirya Village shows a fairly good performance even though it has not yet reached the desired target. At least 72% of drinking water needs in 2 RWs in Cikiray Village can be met with the installation of this hydraulic ram pump,Keywords: huraulic ram pump, clean water, Cikiray villag
