Abstract

Salah satu penyakit yang berbahaya dan dapat menyebabkan angka kematian tinggi yaitu virus Dengue yang di tularkan kepada manusia melalui gigitan nyamuk Demam Berdarah Dengue (Aedes aegypti) betina. Untuk mengurangi penggunaan pestisida sintetik maka diperlukan penggunaan pestisida nabati yaitu ekstrak daun patikan kebo (Euphorbia hirta L.) karena di dalam daun ini terdapat kandungan senyawa metabolit sekunder yang dapat berperan sebagai ovisida. Tujuan penelitian ini adalah untuk mengetahui apakah ekstrak daun patikan kebo (Eupborbia hirta L.) dapat digunakan sebagai ovisida terhadap telur nyamuk Demam Berdarah Dengue (Aedes aegypti), dan mengetahui konsentrasi yang paling efektif dari ekstrak daun patikan kebo (Eupborbia hirta L.) sebagai ovisida nyamuk Demam Berdarah Dengue (Aedes aegypti). Penelitian ini dengan menggunakan metode Rancangan Acak lengkap (RAL) yaitu terdapat empat pengulangan dengan enam perlakuan yaitu kontrol negatif (Aquades) dan kontrol positif (Tween 80) serta konsentrasi 0,125%, 0,25%, 0,5% dan 1 %. Hasil penelitian menunjukkan bahwa, ekstrak daun patikan kebo (Euphorbia hirta L) dapat digunakan sebagai ovisida terhadap telur nyamuk Demam Berdarah Dengue (Aedes aegypti) dari konsentrasi 0,125% - 1%. Semakin tinggi konsentrasi ekstrak daun patikan kebo (Euphorbia hirta L) yang digunakan maka semakin banyak telur yang tidak menetas.

Abstract

In this study, termite bait comprising pinewood of sawdust and a slow action insecticide, fipronil, was made and applied to control subterranean termite Macrotermes gilvus (Hagen) (Isoptera: Termitidae) in Bandung. Colony size was measured using capture-mark-release-recapture prior to the bait application, along with the measurement of wood consumption at each station.  Colony foraging populations at all stations were estimated to be 77,951 termites, with mean wood consumption rates ranging from 0.02 to 6.16 g/station/day. Observation at 18 stations installed with bait consisted of 40 ppm fipronil mixed with pinewood sawdust showed that number of foraging activity termites was effectively reduced in 40 days. It is concluded that fipronil-treated pinewood sawdust bait is effective in controlling the population of foraging M. gilvus workers in 40 days.

Abstract

Steamed cake is a type of cake that is enjoyed by all ages, both children and adults. This cake is usually made from wheat flour. Wheat flour causes dough to rise due to the gluten content. The use of excessive flour can be harmful to health. One alternative effort to replace wheat flour is to combine green bean sprout flour and Ambon banana peel flour. This study aims to determine the antioxidant level, the protein, fat, water, ash, and carbohydrate levels in steamed cakes made from green bean sprout flour and Ambon banana peel flour. This type of research is experimental. Antioxidants were analyzed using the DPPH method, protein was analyzed using the Kjeldahl method, and fat was analyzed using the Soxhlet method. The research results showed that the antioxidant activity in green bean sprout flour was 360.30 ppm which was classified as very weak, banana peel flour was 165.58 ppm which was classified as weak. The highest protein content was in sample T0 at 7.01%, the highest fat content was in sample T0 at 0.77%, the highest water content was in sample T2 at 43.95%, the highest ash content was in sample T3 at 1.15%, and the highest carbohydrate content was in sample T0 at 53.44%.
