ABSTRAKFisika merupakan salah satu ilmu pengetahuan alam (IPA) yang tidak hanya memahami secara teori, namun dibutuhkan pemahaman secara praktis juga. Praktikum adalah salah satu cara untuk dapat memberikan pemahaman secara praktis kepada siswa. Tujuan kegiatan adalah memberikan edukasi dan pendampingan praktikum kepada siswa untuk meningkatkan pemahaman secara teoritis dan praktis melalui program pengabdian kepada masyarakat (PkM). Kegiatan edukasi dan pendampingan praktikum pada alat ukur fisika menggunakan mistar, jangka sorong, mikrometer sekrup dan multimeter.Siswa memiliki rasa kepuasan dan keterampilan yang tinggi ditunjukkan dengan persentase hasil kuesioner untuk kedua aspek yaitu keterampilan dan kepuasan diatas 50%. Melalui kegiatan edukasi dan pendampingan praktikum dapat meningkatkan keterampilan dan kemampuan siswa khususnya pada  alat ukur fisika. Kata kunci: pendidikan; pendampingan; pengabdian masyarakat; fisika. ABSTRACTPhysics is one of natural sciences which is not only needed to understand theoretically, but it is needed practical comprehension. Lab work is a practical way giving  comprehension to students. The aim of this study is providing education and assistance in lab work to students for increasing their theoretical and practical comprehension through dedication to community (PkM). In this study focuses on measuring tools of physiscs, such as ruler, calipers, screw micrometer, and multimeter. The students have great satisfaction and skill which have been showed with percentage of questionnaire result in the both aspects, more than fifty percents. Through education and assistance have been able to improve the students’ skill and ability, particularly  in physics measuring tools. Keywords: education; assistance; dedication to community; physics.

The aim of study is to forecast global tourist visits and compare the forecasting methods to determine the best method using random forest, single exponential smoothing and double exponential smoothing, respectively. These methods are applied in global tourist visit data in West Nusa Tenggara Province. Random forest, single exponential smoothing and double exponential smoothing are familiar methods and are frequently utilized in forecasting. In addition, the three methods have great accuracy for time series data, such as data of global tourist visits. The data used in this study is data of global tourist visits from 2014 to 2021 in West Nusa Tenggara province. Applying the random forest, single exponential smoothing and double exponential smoothing methods in forecasting, the result shows that double exponential smoothing method is the best, based on the smallest value of Mean Absolute Percentage Error (MAPE) of 325.759. The forecasting result found out that tourist visits will increase from previous time, starting from August, 2021 to July, 2021 with an estimated 847 to 1045 lives

Pandemi COVID-19 sangat berdampak pada kehidupan masyarakat dunia khususnya dalam hal kesehatan dan pendidikan. Kurangnya kesadaran tentang pentingnya kesehatan oleh masyarakat di desa serta kurang optimalnya pembelajaran di sekolah membuat anak–anak usia sekolah dasar dan menengah menghabiskan waktu liburnya dengan banyak bermain tanpa menjaga jarak di masa pandemi. Kegiatan PKM ini bertujuan untuk mengurangi kebebasan berinteraksi dan mengoptimalkan pembelajaran anak usia sekolah dasar dan menengah di tengah masa pandemi dengan mengedukasi serta pendampingan pada masyarakat dusun Ketapang desa Menceh. Peserta pada kegiatan ini adalah peserta didik dari tingkat TK (30 orang), SD (50 orang) dan SMP (75 orang). Edukasi kesehatan dilakukan melalui program Posyandu, cuci tangan dan penyuluhan protokol kesehatan sedangkan pendampingan proses belajar–mengajar dilakukan dengan memberikan bimbingan belajar, mengajar TPQ dan pelatihan seperti pembuatan bros dan menggambar. Edukasi tentang kesehatan memberikan pengetahuan arti pentingnya menjaga jarak, kebersihan khususnya di saat pandemi. Bagaimanapun, kegiatan pendampingan pembelajaran dapat memberikan motivasi pentingnya pendidikan saat ini dan masa yang akan datang. Dengan memberikan edukasi tentang kesehatan dan pendampingan dalam pembelajaran kepada masyarakat bisa memahami tentang menjaga kebersihan, menjaga jarak dan juga dapat dijadikan motivasi untuk terus belajar meskipun terkendala khususnya di era pandemi ini.  COVID-19 influences the life of the population worldwide, especially in health and education aspects. Lack of awareness of the meaning of health and the importance of education makes primary and secondary school ages of children spend their time playing without keeping social distancing in this pandemic era. This community service aims to minimize social interaction and optimize their learning during this pandemic by providing education and accompaniment at Ketapang, Menceh village. Education of health was carried out through Posyandu, hand washing and health education programs, while accompaniment program was done by tutoring, teaching TPQ and skill training like drawing, make a brooch. Educating them about health gave them the knowledge of social distancing and hygiene crucial during the pandemic. However, the Accompaniment of education is also essential to motivate motivation that education is essential today, but it is also for the future. By giving education in health and accompaniment in a lesson, they understood that keeping hygiene and social distancing motivated them to continue learning although constrained, especially for this pandemic situation.

This study aims to cluster and visualize the earthquake data on a geographical map to determine earthquakes' characteristics using the k-means algorithm. Cluster analysis using the k-means algorithm was carried out on the earthquake data. K-means algorithm is familiar and is one of the well-known techniques to have been applied in cluster analysis. One of Its advantages in cluster analysis is scaling large datasets, for example, earthquake data. The data used in this study is earthquake data in the West Nusa Tenggara from 1991 to 2021. Applying the proposed k-means algorithm, the optimal number of clusters (k) used in this clustering is 2, based on the highest silhouette score of 0.749. The cluster analysis on the geographical map showed that the epicenters of the earthquakes were pretty spread out before 2018, and the number of earthquakes in the eastern region of West Nusa Tenggara is more than in the western area. However, in 2018, the clusters were all bunched in the northern Lombok region. There were a few earthquakes in the west region in 2018, but they happened before August 5. Even after 2019, most earthquakes continue to occur, with the epicenters clustered close to the northern Lombok region
