Dengue Hemorrhagic Fever (DHF) is a significant health problem in Semarang, Indonesia. A Certain type of insecticides has been widely applied beginning in the last decade as an effort to control the mosquito vectors of dengue virus. This practice could lead to increased resistance in mosquito populations toward these types of insecticides. This research aimed to describe the resistance status of Aedes sp. populations in Semarang. A cross-sectional design study was conducted in 2015, with Aedes sp. populations sampled in several villages of Semarang. Field strains of Aedes sp. eggs were collected using ovitraps and larvae from entomological surveys. Mosquito adults were raised from the collected eggs and larvae under standard conditions and used for biochemical assays. ELISA examined Aedes sp. resistance status. The results showed that there was monooxygenase activity in Aedes sp. populations. In quantitative terms, 77.8% of mosquito samples showed an Optical Density (OD) more than the cutoff point (0.165). Resistance to synthetic pyrethroid insecticide in Aedes sp. mosquitoes population in Semarang may be caused by the mechanism of monooxygenase detoxification enzymes in particular. This case indicated that Aedes sp. has a high capacity as a vector to transmit the dengue virus in Semarang.

INTISARI: Latar Belakang: Tikus merupakan hewan liar yang sering dikaitkan dengan kehidupan manusia dan merugikan di berbagai bidang, salah satunya adalah kesehatan. Di bidang kesehatan, tikus dapat menjadi reservoir beberapa patogen penyebab penyakit pada manusia, salah satunya adalah urine tikus yang dapat menyebabkan leptospirosis. Berdasarkan data Dinas Kesehatan Kota Semarang, populasi tikus tertinggi di Kecamatan Tembalang pada tahun 2019 terdapat di Desa Tandang dengan jumlah tertangkap 164 ekor. Selain itu, pada tahun 2018 terdapat 4 kasus Leptospirosis di Desa Tandang dan Leptospirosis merupakan penyakit infeksi tertinggi di Desa Tandang, Kecamatan Tembalang, Kota Semarang. Tujuan: Menghitung kepadatan populasi tikus hasil perangkap yang berhasil dilakukan dan mengidentifikasi spesies tikus yang ditangkap di Desa Tandang Kota Semarang. Metode: Jenis penelitian yang digunakan adalah penelitian deskriptif dengan metode cross sectional. Sampel dalam penelitian ini adalah seluruh mencit yang ditangkap di RW 03 Desa Tandang Kecamatan Tembalang Kota Semarang dengan menggunakan 100 perangkap hidup selama 2 hari berturut-turut. Hasil: Kepadatan relatif tikus (keberhasilan perangkap) di Desa Tandang adalah 28,1%. Jenis tikus yang paling banyak ditangkap di Desa Tandang adalah Rattus tanezumi yaitu 10 (55,6%) dan Rattus Norvegicus yaitu 8 (44,4%). Sepuluh tikus jantan (55,6%) ditangkap dari 8 tikus betina (44,4%). Kesimpulan: Keberhasilan perangkap di desa Tandang sebesar 28,1% atau termasuk dalam kategori padat.

Dengue Hemorrhagic Fever (DHF) is a disease caused by Dengue virus. In 2016, the number of DHF patients in areas of Health services of Rowosari was 247 cases, IR 289.6/100.000 populations and the highest number of the patients was from Meteseh Village. The most usual mechanism happened in the vertical transmission, transovarial infection, from adult mosquito to the egg. The study was conducted to describe of entomological status of House Index (HI), Container Index (CI), Breteau Index (BI), House index (HI), Ovitrap Index (OI) of larvae as well as transovarial infection in Aedes sp. The research method was descriptive method by conducting test to the entomology status of DHF incidence. Based on the survey in Meteseh sub-village (XVI), a result found that average House Index 8.99%, Container Index 2.88%, Breteau Index 16.40%, HI 8,99 Ovitrap Index 35.46% with the egg density at 1.023 eggs. The identified mosquitoes were 30, and from the identification result of Aedes sp., two Aedes species were found, 28 Aedes aegypti,and only 2 Aedes albopictus. The transovarial infection in Aedes sp. using ELISA method was found 6 mosquito samples which were positive of dengue virus, with the detail in neighborhood 01 (1 sample), neighborhood 02 (2 samples), neighborhood 03 (3 samples). DHF in Meteseh Sub village in Semarang City was probably happened because correlated with transovarial infection.

Ovitrap has been developed and used in many countries as a monitoring tool of dengue vector. The aim of this study was to compare the effectiveness of modified ovitrap and standard ovitrap, as well as measuring the population of Aedes sp. This study was performed in Sidorejo Lor Village Central Java. A pair of conventional and modified ovitrap was put in 100 houses each. Ovitraps were placed indoor and outdoor, in the distance of 100 meters. The results of the study showed that modified ovitrap collected significantly larger numbers of Aedes sp than standard ovitrap. Numbers of Ae. aegypti (68.61%) was higher than Ae. albopictus (30.78%). Mixed breeding outdoor (11.21%) were higher than indoors (3.57%). The value of Area Ovitrap Index (AOI) and Monthly Ovitrap Index (MOI) of modified ovitrap was greater than standard ovitrap. Modified ovitrap can be recommended as a tool for monitoring population of Aedes sp.

The prevalence of hypertension in Indonesia has increased every year. Hypertension does not only affect the elderly but also young people. There is no research yet about description of the knowledge and attitudes related to hypertension prevention among Diponegoro University students The aim of this study was to describe the knowledge and attitudes of students related to hypertension prevention. This type of study is descriptive observational with cross-sectional study design. The sample of this study amounted to 425 respondents obtained using accidental sampling technique. The variables studied were gender, type of study, family history of hypertension, and level of family support.The results showed that majority of the respondents were female (76,5%), the type of study was non-health (50,6%), did not have a family history of hypertension (60%), had a family that supported the prevention of hypertension (50,6%). A total of 51,5% of respondents have a good level of knowledge, 52% of respondents have a good attitude. From the result was concluded that the majority of students already have a good level of knowledge and attitudes related to hypertension prevention. It is necessary to increase student awareness about hypertension, especially related to hypertension prevention.
