Abstract

The tongue-in-law plant (Sansevieria trifasciata Prain) contains saponins, flavonoids, steroids and triterpenoids which are natural metabolites that have the potential to control agricultural pests such as armyworms (Spodoptera sp.). Therefore, the aim of this study was to determine the mortality and LC50 value for 72 hours of giving in-law tongue plant extract to Spodoptera litura and the length of the life cycle of S. litura in the laboratory. The research method used a completely randomized design (CRD). The extract of the tongue-in-law plant is obtained from the maceration process of the tongue-in-law plant with ethanol and then concentrated using a rotary evaporator until the thick extract is obtained. The results of the research on the ethanol extract of the tongue-in-law plant on the mortality of S. litura, found that the highest mortality was 63.6% at a concentration of 800 ppm and the lowest mortality value was 36.4% at a concentration of 200 ppm for 72 hours.Tanaman lidah mertua (Sansevieria trifasciata Prain) mengandung saponin, flavonoid, steroid, dan triterpenoid yang merupakan metabolit alami yang berpotensi untuk mengendalikan hama pertanian seperti ulat grayak (Spodoptera sp.). Oleh karena itu, tujuan dari penelitian ini adalah untuk mengetahui mortalitas dan nilai LC50 selama 72 jam pemberian ekstrak tumbuhan lidah mertua terhadap Spodoptera litura dan lamanya siklus hidup S. litura di laboratorium. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL). Ekstrak tumbuhan lidah mertua diperoleh dari proses maserasi tumbuhan lidah mertua dengan etanol kemudian dipekatkan menggunakan rotary evaporator hingga diperoleh ekstrak kental. Hasil penelitian ekstrak etanol tumbuhan lidah mertua terhadap mortalitas S. litura didapatkan mortalitas tertinggi sebesar 63,6% pada konsentrasi 800 ppm dan nilai mortalitas terendah pada konsentrasi 36,4%. 200 ppm selama 72 jam.Kata kunci: mortalitas, Sansevieria trifasciata, Spodoptera litura DOI: http://dx.doi.org/10.23960/jbt.v8i3.21591

Abstract

After 2 years of pandemic which caused by corona virus and followed by Restrictions Towards Community Activities (PPKM) was issued by government, has caused negative impact on various sector of community life. The impact on economic sector of society was quite large. Hence, community economic wheels which disrupted by laid off / stay home policy, needs to be maintained by offering home business with low budget. One of community empowerment efforts that can be introduced to society is utilization of household waste / small scale / fresh market to keep maggot black soldier fly (BSF). This maggot BSF is kind of clean fly and not classified as disease vector, otherwise it has many benefits as chicken feed, fish feed, substitution for protein feed, bird feed etc. Maggot has become alternative protein as animal feed. After the participant satisfaction test was held, we got participant satisfaction average values, ranged from very good (rated as 5) 60.2 %, good (rated as 4) 38.6%, and fair (rated as 3) 1.2 %. Overall, all participants were greatly satisfied with our presentation about mentioned knowledge and technology.

Abstract

Knowledge of the diversity of dragonflies (Odonata) is very important for river management which is used for various purposes by humans. This research aims to determine the diversity of Odonata in the waters of Bendungan Lempake, Karang Mumus River, and Berambai River Samarinda. Sampling was done by using purposive sampling technique through insect net with transect method along with the river flow, 5 times at each location for one month in the morning and evening. The samples obtained were prepared, stored on triangular paper containing camphor, and identified using entomological guidelines. Environmental temperature, humidity, and acidity of the water are calculated using standard measurement tools. Data is displayed in the form of the number of types and a description of each type. The results showed that 1025 individual dragonflies were found belonging to 22 species and 4 families of Odonata. The diversity index value (H') of dragonflies in the waters of the Bendungan Lempake is 2.83, the Karang Mumus River is 2.52 and the Berambai River is 2.53, which are classified as a medium category. The conclusion of this research is that the waters of Bendungan Lempake, Karang Mumus River, and Berambai River are still supporting as habitat for dragonflies to live and breed.
