The pandemic period forces all learning processes to be carried out online by utilizing internet facilities with a laptop. The position of using a laptop that is not ergonomic can cause musculoskeletal disorder. This study aims to determine the correlation between position and duration of student use of laptops during online learning with Musculoskeletal Disorders (MSDs). This research is analytic observational with a cross-sectional approach. The research was conducted on active students of the Medical Study Program, Muhammadiyah Palembang University, with 416 respondents. Primary data collection was taken using a questionnaire with a Nordic Body Map score. The analysis technique used the Chi-Square test. The results showed that the respondents had a high duration of laptop use (48.8%), with a not good position (42.3%).Most musculoskeletal disorders were felt in the neck (75.5%). There was a correlation between the position of using a laptop and musculoskeletal disorders (p 0.652). However, there was no correlation between the duration of laptop use and musculoskeletal disorders (p 0.002). It can be concluded that the position of using a laptop that is not ergonomic caused musculoskeletal disorders.

Soil-transmitted helminth (STH) prevalence is high worldwide. School-aged children are at risk of infection due to poor self-hygiene and contaminated soil and water. Anemia is caused by infection in children, and it affects cognitive development, physical development, and school performance. To ascertain the relationship and distribution of STH and anemia in elementary school students, as the cross-sectional objectives. Students from SDN 96 and 97 Palembang participated in the study. Using stratified random sampling, 84 students from grades 4, 5, and 6 were chosen at random. Anemia is diagnosed through a test using the Quick Check hemoglobin method. They discovered that 40.5 percent of students had intestinal worms, 15.5 percent were anemic, and 11.8 percent were both anemic and worm-infected. A p-value of 0.438 was obtained from the chi-square bivariate analysis. There is no link between STH and anemia.

Clean water reservoirs can become mosquito breeding grounds because water comes from rainwater, water wells, and taps, making them an ideal breeding ground for the Aedes aegypti mosquito vector of the dengue virus. This study aims to determine the hatchability of eggs and the growth of Aedes aegypti in three different types of brooding water in Sako Village, Palembang City. This study is experimental. The sample contains 1200 Aedes aegypti eggs collected from the Health Research and Development Center (Balitbangkes), the Ministry of Health of Indonesia in Baturaja, as well as three types of water collected from the homes of residents suffering from Dengue Hemorrhagic Fever in Sako Village, Sako District, Palembang City. Data was collected through direct observation for 5 days of egg hatching in the third water, which was repeated three times. The study's results were analyzed by the ANOVA, Honest Significant Difference test (BNJ), and R studio software version 4.1.2. The average number of mosquito eggs that hatched in well water was 77.67%, rainwater was 63,335, tap water was 54.67%, and control was 72.33%. There were significant differences in the effects of the three types of air on the larval and pupal stages of Aedes aegypti development. This study shows that Aedes aegypti mosquitos can breed into adults outside of clean water and water that contains soil, such as water wells. Abstrak: Tempat penampungan air bersih dapat menjadi sarang nyamuk, air berasal dapat berasal dari air hujan, sumur air dan ledeng sehingga menyediakan tempat yang baik bagi nyamuk Aedes aegypti vektor virus dengue untuk berkembang biak.  Penelitian ini bertujuan untuk mengetahui daya tetas telur dan perkembangan Aedes aegypti pada tiga jenis air perindukan di Kelurahan Sako Kota Palembang. Penelitian ini merupakan penelitian eksperimental. Sampel terdiri dari 1200 butir telur Aedes aegypti yang diperoleh dari Litbangkes Kemenkes Baturaja dan tiga jenis air yang diambil dari dari rumah warga yang menderita penyakit Demam Berdarah Dengue yang bertempat tinggal dan menetap di Kelurahan Sako, Kecamatan Sako, Kota Palembang. Pengumpulan data diperoleh dengan melakukan pengamatan langsung selama lima hari terhadap penetasan telur pada ketiga air tersebut yang dilakukan sebanyak tiga kali pengulangan. Hasil penelitian di analisis menggunakan ANOVA, uji Beda Nyata Jujur (BNJ) dan software R studio version 4.1.2. Hasil penelitian menunjukkan rata-rata jumlah telur nyamuk yang menetas di air sumur mencapai 77,67%, air hujan 63,335, dan air PDAM 54,67% dan kontrol sebesar 72,33%. Terdapat perbedaan yang siginfikan pengaruh tiga jenis air terhadap perkembangan stadia larva dan pupa Aedes aegypti. Penelitian ini membuktikan bahwa nyamuk Aedes aegypti mampu berkembang biak menjadi dewasa di luar media air bersih dan air yang dasarnya mengandung tanah seperti air sumur.

The Culex quinquefasciatus mosquito is the main vector of filariasis, various ways to control vector breeding is the use of insecticide from natural ingredients, one of which is basil containing essential oils and proven is effective as a repellent against the mosquito. The objective of this research was to determine the repellent potency of n-hexane extract of basil leaves and stems against the Culex quinquefasciatus. This study was a laboratory experimental study using a completely randomized design, with 3 replications at 7 times intervals. The extract concentrations were 15%, 25%, 35 % and ethanol negative control 96%, the positive control repellent X containing 13% DEET. The results showed that the n-hexane extracts of basil leaves and stems for 6 hours at all concentrations were able to repel mosquitoes up to 92.51%, the one-way ANOVA analysis showed that the value of p= 0.000 (< 0.05), meaning that there was a difference in the number of C. quinquefasciatus perching on the black cloth at various concentrations of n-hexane extracts of leaves and stems of basil, while the probit analysis showed that the effective extract concentration at 90% was 31.52%. The extract of n-hexane leaves and basil stems was effective as a repellent against the C. quinquefasciatus.
