Abstract

Indonesia, the fourth most populous country in the world with 275.5 million people, faces increasing human activity that can lead to negative impacts such as the spread of infectious diseases. One of these diseases is Dengue Hemorrhagic Fever (DHF), which is particularly susceptible in residential areas with poor environmental hygiene. The rising number of DHF cases on Lombok Island is a significant concern. This study employs a spatial analysis modeling approach, specifically the Spatial Autoregressive Poisson (SAR Poisson) model, which considers the spatial dependence of dengue cases assumed to follow a Poisson distribution. The objective is to model and map the potential distribution of DHF cases on Lombok Island in 2021. The analysis reveals spatial autocorrelation in the data based on Moran's I. Significant variables affecting DHF cases include the number of permanent sanitation facilities (X2) and the number of drinking water facilities (X3). Mapping results based on the SAR Poisson model indicate that the distribution of DHF cases is relatively uniform across most sub-districts, with the highest incidence suspected in Tanjung Sub-district

Abstract

The use of technology in the world of education is a must where digital technology is currently an important part in supporting teaching and learning activities. Professional teachers have the obligation to plan learning, carry out quality learning processes, as well as assess and evaluate learning outcomes, so to carry out these obligations the first step a teacher must take is to design all learning tools. To improve this, it is considered important to provide workshops or training on Android-based learning media design. The workshop was carried out for one full day with details of the provision of materials, practice of making electronic applications and mentoring of participants after the workshop activities were completed. With the aim of increasing teacher competence in designing and utilizing android-based learning media in the learning process in the classroom. The workshop will be held on Saturday, August 6, 2022 at SMAN 2 Selong. The results of the workshop illustrate that participants have been able to create android-based learning media applications.

Abstract

Accreditation is an acknowledgment from an accreditation body that an institution maintains a certain level of educational standards. Educational accreditation is a quality assurance process by which services and operating institutions, or educational programs are evaluated and verified by an external body to determine whether recognized and accepted standards are being met. If standards are met, accredited status is granted by the appropriate agency. To prepare for this it is considered important to provide assistance to every school that needs it, as was done by SDN 3 Suralaga. Assistance is carried out for 2 months, from April to May 2022. Assistance is carried out through 4 stages, namely 1) presentation of accreditation instrument material, 2) discussion and assistance on school readiness for accreditation, 3) physical evidence assistance, 4) preparation of physical evidence and 5) evaluation of sensitivity. The results of the assistance show that 1) the physical evidence prepared by each teacher who is given the task as the person in charge is ready and complete and 2) the school is ready for visitation.

Abstract

The uniqueness and cultural diversity of traditional communities as reflected in ideas, activities and artifacts can be studied and used as a source of learning mathematics. Most people view that mathematics is not related to culture or is culturally independent. The development of mathematics in society through cultural activities can be studied through ethnomathematics studies that can bring mathematics closer to student culture. Thus, this study aims to explore the number system and cultural meaning that developed in the Sasak people which can be used as a source of learning mathematics on the island of Lombok. This research is a research with ethnographic method. Research data was collected through observation, literature study, and interviews with cultural practitioners, traditional chief leaders, traditional leaders, Sasak cultural researchers and humanists. The results of this study indicate that the development of the number system has been developing for a long time in the Sasak people. Counting activities (bejinah) use arithmetic operations as is done in general but with local terms, namely total (rombok), less (sedik), times (kali) and divide (bagi). The developing number system is understood as a number in quantitative and qualitative form, in unit or set numbers. There are 5 types of unit or set numbers known by the Sasak people, namely bond units, measuring units for solid objects, measuring units for liquid objects, area units and length units. The mathematical concepts found in the activities of the Sasak people can be used as a source of learning and as a starting point in learning mathematics

Abstract

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

Abstract

In the context of cultural anthropology, people have known various mathematical activities, such as counting, measuring, and weighting, which have different terms based on each culture. We understand that mathematics emerges from people activities in responding to the existence of their environment. Sasak people conduct various cultural activities in their daily life. One of which is in agriculture and in the form of traditional arts, therefore, this study aims to build mathematical conceptions by exploring the activities of Sasak culture that can be integrated into mathematics learning contextually. This study was an ethnographic research. Data were collected through various literature studies, field observations, and interviews with savvy informants regarding Sasak culture, traditional farming system, and Sasak traditional arts. Research results indicated that the culture of Sasak people relevant with principles and characteristics of Realistic Mathematics Education (RME) is a learning approach that can be integrated, both explicitly and implicitly

Abstract

This preliminary study investigated the reproductive biology of three rabbitfish species Siganus doliatus, Siganus canaliculatus, and Siganus puellus collected from Sopura Bay, Kolaka Regency, Southeast Sulawesi. A total of 351 individuals were analyzed between September and November 2025 to determine sex ratio, gonad maturity stages, gonadosomatic index (GSI), and length at first gonad maturity (Lₘ). The results showed male-biased populations in S. puellus (1.53:1) and S. doliatus (1.82:1), while S. canaliculatus exhibited a balanced sex ratio (1.01:1). Most individuals were at gonad maturity stages III–IV, indicating active gonadal development during the sampling period, with the spawning peak estimated in late October to November. The Lₘ values differed between species and sexes, suggesting adaptive reproductive strategies, where males generally matured at smaller sizes than females. The highest GSI values were recorded in S. puellus, indicating higher reproductive activity. These findings provide essential baseline data for understanding reproductive patterns and support sustainable management of rabbitfish resources in Sopura Bay

Abstract

Pemetaan wilayah berdasarkan kondisi kesehatan penting untuk mengidentifikasi ketimpangan pelayanan dan menentukan prioritas intervensi. Provinsi Nusa Tenggara Barat menghadapi tantangan berupa distribusi fasilitas kesehatan yang belum merata serta peningkatan kasus penyakit menular. Penelitian ini bertujuan mengelompokkan Kabupaten/Kota berdasarkan ketersediaan fasilitas kesehatan dan prevalensi penyakit menular menggunakan metode Fuzzy Possibilistic C-Means (FPCM). Variabel yang digunakan meliputi jumlah puskesmas, rumah sakit, serta kasus tuberkulosis, HIV/AIDS, demam berdarah, dan diare. Evaluasi hasil klasterisasi menggunakan Partition Entropy (PE), Partition Coefficient (PC), dan Modified Partition Coefficient (MPC) menunjukkan konfigurasi optimal pada tiga cluster (PE = 0.6125239, PC = 0.9798644, dan MPC = 0.9697966). Profilisasi hasil klaster menunjukkan bahwa Cluster 1 terdiri dari daerah-daerah dengan ketersediaan fasilitas kesehatan yang relatif rendah serta tingkat prevalensi penyakit menular yang tinggi. Cluster 3 mencakup wilayah dengan fasilitas kesehatan yang lebih memadai, namun tetap menghadapi beban penyakit menular yang signifikan. Cluster 2 mencakup wilayah dengan fasilitas kesehatan yang tinggi sedangkan kasus penyakit menular yang rata-rata rendah. Temuan ini menunjukkan pentingnya pendekatan berbasis data dalam mendukung perencanaan intervensi kesehatan yang lebih terfokus dan responsif terhadap kebutuhan masing-masing wilayah di Provinsi Nusa Tenggara Barat.
