Abstract

Termites (Coptotermes curvignathus) are considered more dangerous than other termite species as they can cause significant damage to plantation and agricultural crops, with widespread distribution. The use of chemical pesticides to control this pest can lead to resistance and have negative impacts on the environment and human health. An environmentally friendly solution involves utilizing natural plants/substances as botanical insecticides, such as rice washing water and local microorganism (MOL) water. The aim of this research is to evaluate the effects of these two substances on termite population control and determine the optimal formulation that can act as a termite repellent. and to determine the optimal formulation as an anti-termite. The research methodology involves determining formulations of botanical insecticides, namely 100% rice washing water, 100% MOL water, 50% rice washing water : 50% MOL water, 75% rice washing water : 25% MOL water, 25% rice washing water : 75% MOL water. Each test box is filled 5 soldier termites and 20 worker termites, then provided with test papers that have been soaked in the predetermined formulation. Each treatment is repeated three times and observed every 24 hours for 72 hours. The research results indicate that all formulations uses did not have a significant impact on termite mortality. It can be concluded that the use of rice washing water and MOL water in the tested formulations is not effective as an insecticide to control termite.

Abstract

Candida was a fungus that can cause candidiasis infection. Candidiasis could occur of the skin, nails, mucous membranes and the gastrointestinal. The study aims to examine whether Auricularia nigricans methanol extract has the ability to inhibit the growth of Candida albicans, C. glabrata, and C. parapsilosis. Soxhletation was used as the extraction method, and the inhibitory test method involved diffusion paper disk and wells methods. The concentration variations used were 0.2 g/ml, 0.25 g/ml and 0.3 g/ml with 10% DMSO as a negative control. The research results obtained were that no inhibition zones were formed at concentrations of 0.2 g/ml, 0.25 g/ml and 0.3 g/ml so that they were included in the inactive category. Keywords: Auricularia nigricans, Candida, soxhlet method, methanol extract, paper disc and wells method.   Abstrak Candida merupakan jamur golongan khamir yang dapat menyebabkan infeksi kandidiasis. Kandidiasis tersebut dapat terjadi pada kulit, kuku, membran mukosa dan saluran cerna. Penelitian ini bertujuan untuk mengetahui kemampuan ekstrak metanol Auricularia nigricans dalam menghambat pertumbuhan C. albicans, C. glabrata dan C. parapsilosis. Metode ekstraksi yang digunakan adalah sokletasi selama 10 jam dan metode uji daya hambat antifunginya secara difusi cakram dan sumuran. Variasi konsentrasi yang digunakan adalah 0,2 g/ml, 0,25 g/ml dan 0,3 g/ml dengan DMSO 10% sebagai kontrol negatif. Hasil penelitian yang diperoleh adalah tidak terbentuknya zona hambat pada konsentrasi 0,2 g/ml, 0,25 g/ml dan 0,3 g/ml sehingga termasuk dalam kategori tidak aktif. Kata kunci: Auricularia nigricans, Candida, metode sokletasi, ekstrak metanol, metode difusi cakram dan sumuran.
