Abstract

Salah satu masalah kesehatan untuk negara beriklim tropis dan subtropis adalah Demam Berdarah Dengue (DBD). Sepanjang 2021, ada 73.518 kasus DBD di Indonesia dengan 2.697 kasus terjadi di NTB dengan kasus kematian yang disebabkan oleh DBD sebanyak 21 kasus. Penyakit DBD dengan prediksi perkembangan jumlah penderita yang terinfeksi dapat dimodelkan dengan menggunakan model matematis epidemiologi yaitu model persamaan diferensial nonlinear SIR yang diklasifikasi ke dalam tiga kompartemen yaitu S (Susceptible), I (Infectious), dan R (Recovered) serta dapat disimulasikan dengan neural network. Dalam neural network, terdapat ide untuk melakukan pemetaan suatu fungsi pada konsep classifier yaitu pengklasifikasian objek dengan memanfaatkan persamaan linear, 𝑦 = 𝑓(𝑥) untuk meregresi data. Data yang digunakan adalah data sekunder yang bersumber dari Dinas Kesahatan Provinsi NTB. Data yang diperoleh kemudian dianalisis sehingga memperoleh titik keseimbangan. Dari hasil analisis model SIR penyebaran penyakit deman berdarah di NTB diperoleh dua titik keseimbangan namun hanya satu titik yang stabil asimtotik karena semua nilai eigen yang diperoleh bernilai negatif. Nilai dari , artinya titik keseimbangan bebas penyakit demam berdarah di NTB berangsur-angsur akan menghilang.

Abstract

The Agricultural Census 2023 (ST2023) is a large-scale activity carried out by BPS. The series of ST2023 activities consists of planning, preparation, data collection, data processing, presentation and data analysis. One of the data processing stages is inputting documents using the Document Management System (SIPMEN). The SIPMEN application is used by all work units at BPS throughout Indonesia which carry out ST2023 data collection using the Paper Assisted Personal Interviewing (PAPI) method. The purpose of using the SIPMEN application by BPS East Lombok Regency is to facilitate the management of ST2023 documents starting from the document distribution process, namely receipt from BPS NTB Province to the process of receiving documents from BPS East Lombok Regency data collection, namely batching (grouping) documents.

Abstract

Geometry is one of the fundamental topics in mathematics, playing a crucial role in understanding shapes, sizes, positions, and spatial relationships between objects. Mastery of this concept is essential; however, in practice, many students still struggle to grasp geometry material. This issue is also evident at SMA Negeri 1 Pujut, where several students demonstrate a low level of understanding of geometric concepts. In response to this problem, the aim of the research is a community service activity was carried out in the form of tutoring sessions focused on improving students' understanding of geometry. This activity employed a visualization approach through function graph sketches to help students better comprehend the interconnections between concepts in a more concrete way. Based on the evaluation results, data showed that 86.67% of students exhibited improved learning outcomes after participating in the activity. This achievement indicates that the instructional method used by the facilitators was quite effective and well-received by the majority of participants.

Abstract

Mastery of mathematical problem-solving skills based on logical reasoning is an important aspect in supporting students’ success in facing the Computer-Based Written Examination (UTBK). However, many students still encounter difficulties in understanding concepts and effectively solving UTBK-type questions. To address this issue, a community service program was conducted at SMA Negeri 1 Pujut with the aim of enhancing participants’ mathematical reasoning capacity. The activity began with an introduction to the Mathematics study program, followed by training sessions on strengthening concept mastery through logical reasoning and practice in solving UTBK questions, delivered by lecturers and students. The effectiveness of the training was evaluated through a comparison of participants’ pre-test and post-test results. This activity was attended by 30 students as training participants. The evaluation showed a significant improvement in post-test scores, with 83.33% of participants experiencing an increase in their scores, and the majority achieving above 60 in the post-test. These findings indicate that the applied training method was effective in improving students’ conceptual understanding of mathematics and their readiness to face the UTBK.
