OVERVIEW OF VACCINE-PREVENTABLE DISEASES SURVEILLANCE AND COMPLETE BASIC IMMUNIZATION COVERAGE AT CAMELIA POSYANDU
Full text linkVaccine-preventable diseases (VPDs) remain a global health challenge. In Indonesia, immunization coverage has not yet reached the national target, particularly in East Nusa Tenggara Province, which recorded only 79.04% coverage in 2024. This study aimed to describe VPD surveillance and immunization coverage at the Camelia Integrated Health Service Post, involving 30 toddlers, through examination of health cards and interviews. The study used a qualitative approach with a retrospective descriptive analytical design. Surveillance was conducted through five stages: data collection, monthly data processing, analysis, ACER reporting, and follow-up in the form of catch-up immunization. The results showed that 33.3% of children were fully immunized on time, 30% experienced delayed immunization, and 36.7% had incomplete immunization status. DPT-HB-Hib (32.8%) and oral polio vaccine (23%) were the most frequently delayed vaccines due to parents’ lack of knowledge, concerns about side effects, child illness, busy schedules, limited access to services, and insufficient family support. The study concluded that although immunization coverage was not yet optimal, the implementation of VPD surveillance and a consistent catch-up immunization program effectively prevented VPD cases in the Camelia Posyandu area. Recommendations include strengthening digital recording systems, continuing health education, implementing digital reminder systems, optimizing home visits, and conducting periodic evaluations

OVERVIEW OF MALARIA SURVEILLANCE IN THE ELIMINATION PHASE AT THE OESAPA COMMUNITY HEALTH CENTER
Full text linkMalaria remains a significant public health challenge, particularly in regions that have achieved elimination but remain vulnerable to imported cases due to high population mobility. This study describes the malaria surveillance system at the Oesapa Community Health Center during the elimination phase, specifically assessing its readiness to detect, report, and respond to cases in a timely. Employing a qualitative descriptive design, the study involved five key informants through in-depth interviews and document reviews, followed by a narrative analysis of planning, implementation, monitoring, and evaluation. The results indicate that all surveillance stages align with national guidelines, including data-driven planning, early detection via laboratory testing, travel history recording, and routine reporting.

MARKET REACTION TO THE RATIFICATION OF “RUU IBU KOTA NUSANTARA”
Full text linkResearch Purposes. This study aims to analyse the Indonesian capital market’s reaction to the ratification of the “RUU Ibu Kota Nusantara” using abnormal return (AR) and trading volume activity (TVA) on IDX30 companies.
Research Methods The study applies an event study approach using the market model and a paired-samples t-test to secondary data from 2022, including daily stock prices, the composite index (IHSG), and trading volume.
Research Results and Findings. The findings indicate a significant market reaction on the tenth day prior to the event, characterized by positive AR, suggesting the market's positive anticipation of the bill's ratification. However, during other periods, the market reaction was not significant, implying that the announcement's impact was temporary. For TVA, the paired-samples t-test results reveal a significant difference between the pre- and post-enactment periods, indicating an increase in stock trading volume following the announcement. This study concludes that the enactment of the Nusantara Capital City Bill had a temporary impact on market reaction and increased stock trading volume activity. These findings provide empirical evidence for investors and the government to better understand how significant policies influence the capital market and support more informed investment decision-making
PROTOCOL OPTIMIZATION OF RT-qPCR FOR NF-ΚB DETECTION IN CARDIAC TISSUE FROM HFHS-FED MICE
Full text linkAccurate detection of gene expression in challenging tissues requires methodological optimization to ensure reproducibility. Cardiac tissue, with its low cell density and variable RNA yield, presents particular difficulties for RT‑qPCR analysis. This study aimed to refine NF‑κB detection in HFHS‑fed C57BL/6 mice by comparing a standard 2‑ΔΔCt approach with an optimized protocol incorporating individualized calibrators adjusted for RNA concentration. Six male mice were divided into standard-diet (STD) and high‑fat, high‑sucrose (HFHS) groups, and cardiac RNA was extracted after 8 weeks of feeding. While relative NF‑κB expression trends were higher in the HFHS group, differences were not statistically significant; however, the optimized method consistently reduced variability and improved measurement reliability compared to the generalized approach. These findings highlight the value of individualized calibration as a protocol refinement for RT‑qPCR, offering a more rational framework for gene expression analysis in heterogeneous or technically demanding tissue samples
Meningkatkan Kemampuan Membaca melalui Kegiatan Peningkatan Kosakata (Vocabulary) untuk Siswa Kelas Delapan Di SMPN 1 Jabon
No full textEnglish is considered one of the most difficult subjects to learn, leading to students’ low learning motivation. At SMPN 1 Jabon, despite ample study hours and easy assignments and materials given by the teacher, many students have difficulty learning English. Students in class VIII, especially VIII-E, still face obstacles in understanding reading. Although they have been given exercises to answer questions related to the passage, they still have difficulty answering them. A very limited understanding of vocabulary contributes to this issue. The researcher conducted a classroom action research related to students' vocabulary mastery to help improve students' reading ability and English language mastery. This research was conducted in several cycles. Each cycle consisted of Plan-Do-Look-Reflect activities. The researcher planned two cycles to provide two treatments to the students. Cycle 1 presented the treatment using Vocabulary Self-Collection Strategy (VSS). For the second cycle, the researcher applied the word clustering strategy as a vocabulary development activity. Based on the data from the posttest in cycle 1 and cycle 2, students' reading comprehension developed in general. This can be seen from the results of the posttest of cycle 2. 67% of students met the minimum reading comprehension score standard (75 points).Dibandingkan dengan mata pelajaran lainnya, Bahasa Inggris dianggap salah satu yang paling sulit dipelajari sehingga menimbulkan kurangnya motivasi siswa untuk belajar. Di SMPN 1 Jabon, banyak siswa yang kesulitan belajar bahasa Inggris walaupun mereka memiliki banyak jam belajar dalam seminggu dan guru juga memberikan tugas dan materi yang mudah kepada siswa. Siswa kelas VIII khususnya VIII-E masih menghadapi kendala dalam memahami bacaan. Walaupun mereka telah diberikan latihan untuk menjawab pertanyaan-pertanyaan yang berkaitan dengan bagian tersebut, mereka masih kesulitan untuk menjawabnya. Salah satu penyebab yang mendasari permasalahan ini adalah pemahaman kosakata yang sangat terbatas. Peneliti melakukan penelitian tindakan kelas terkait dengan penguasaan kosakata siswa untuk membantu meningkatkan kemampuan membaca dan penguasaan bahasa Inggris siswa. Penelitian tindakan kelas ini dilaksanakan dalam beberapa siklus. Setiap siklus terdiri dari kegiatan Rencana-Lakukan-Lihat-Renungkan. Peneliti merencanakan dua siklus untuk memberikan dua perlakuan kepada siswa. Siklus 1 menyajikan perlakuan menggunakan Vocabulary Self-Collection Strategy (VSS). Untuk siklus kedua, peneliti menerapkan strategi pengelompokan kata sebagai aktivitas pengembangan kosakata. Berdasarkan data yang diambil dari posttest pada siklus 1 dan siklus 2, pemahaman membaca siswa berkembang secara umum. Hal ini terlihat dari hasil posttest siklus 2. 67% siswa telah memenuhi standar skor minimum pelajaran Bahasa Inggris yaitu 75 poin

Synthetic Earthquake Accelerogram of Kupang City Based on SNI 8899:2020
Full text linkIn order to make it a sustainable and safe city as a settlement, Kupang City requires the availability of earthquake-resistant buildings because its location on Timor Island is in an earthquake-prone area. In designing earthquake-resistant buildings, there is a method, namely the time history analysis method, which better shows the actual conditions at the time of the earthquake because it includes earthquake load parameters in the time function (dynamic load). This method requires an earthquake accelerogram as an earthquake load in the analysis process. Not all areas have earthquake accelerogram recordings, so it is necessary to create a synthetic earthquake accelerogram as a substitute for the earthquake accelerogram at the location where a building will be planned. In this paper, eleven pairs of synthetic accelerograms were created for the Kupang City location for the medium soil site class (SD) by referring to SNI 8899:2020 and the Indonesian Earthquake Hazard Deaggregation Map for Earthquake Resistant Infrastructure Planning and Evaluation which is a derivative of SNI 1726:2019. The creation of synthetic earthquake accelerograms in this paper uses the Amplitude Scaling Method using a period range of 0.2 seconds - 2 seconds for three earthquake source mechanisms, namely the Benioff earthquake source, the Shallow Fault earthquake source, and the Megathrust earthquake source. From each earthquake source, eleven pairs of horizontal earthquake accelerograms were taken that met the location criteria and then selected based on the significant duration of each pair of accelerograms. The results of the study are eleven pairs of synthetic earthquake accelerograms for the Kupang City location which can be used as dynamic earthquake loads in time history analysis. The eleven synthetic accelerograms are modifications of the original earthquake accelerograms on the earthquake accelerogram database website with the following Regional Seismic Network (RSN) numbers: RSN 9, RSN 36, RSN 51, RSN 4007390, RSN 4017018, RSN 4017032, RSN 4017055, RSN 4032461, RSN 4028440, RSN 4028606, and RSN 4032589
