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.

Abstract

Mushrooms are a source of antioxidants. Mushrooms can be processed into various products. Both raw materials and finished products from mushrooms must comply with established standards. The aim of this research was to determine the total plate count and total fungal count in Ganoderma lucidum and Pleurotus ostreatus samples. The method used is the Total Plate Count (TPC) and Total Fungal Count (TFC). The TPC value in G. lucidum was 6.4 x 106 CFU/g and TFC was 3.9 x 105 CFU/g. This value exceeds the BPOM maximum standard for tea products or herbal brews. The TPC value in P. ostreatus was 1.2 x 105 CFU/g and TFC was 4.9 x 105 CFU/g. The TPC value for P. ostreatus is less than the maximum standard set by BPOM, while the TFC value exceeds the maximum standard for powder or mixture of soup and broth. The conclusion of this research is that the TPC and TFC in the G. lucidum and P. ostreatus samples exceed the standards set by BPOM No. 13 of 2019 except for the TPC in the P. ostreatus sample.

Abstract

The donkey ear taro plant (Alocasia polly) is an ornamental Araceae family plant with broad leaves capable of absorbing air pollutants. This research examined the macroscopic and microscopic characteristics of A. polly leaves for botanical identification and pharmaceutical potential assessment. The research methods included sample preparation and macroscopic, organoleptic, and microscopic observations of fresh leaves and leaf powder. Macroscopic observations revealed shield-shaped leaves (peltatus) with pointed tips (acuminatus), ear-like lobed base (auriculatus), smooth glossy surface (nitidus), dark green upper surface, purplish lower surface, pinnate venation (penninervis), and wavy margins (repandus). The leaves averaged 33 cm in length and 16.5 cm in width. Organoleptic examination showed fresh leaves with dark green upper surfaces and purplish-brown lower surfaces, characteristic leaf aroma, and tasteless properties. The leaf powder exhibited similar dark green coloration, characteristic aroma, and tasteless qualities. Microscopic analysis of both fresh leaves and powder revealed epidermal cell structures, spiral-type vascular bundles, anomocytic stomata, multicellular and unicellular trichomes, and calcium oxalate crystals. These findings provide fundamental botanical identification data for A. polly leaves. Further research is recommended, including non-specific parameter testing and phytochemical screening, to explore the plant's pharmacological potential more comprehensively.

Abstract

Medicinal plants are a rich source of secondary metabolites, which have tremendous potential in the development and discovery of new drugs. Mint leaves are used to treat diarrhea and diarrhoea, hypertension, liver and spleen infections, asthma, rheumatic pain, joint irritation, sensitivity and jaundice. The menthol content in natural mint ointment is used in the medicine, perfumery and food businesses. This research aims to determine the yield and content of active secondary metabolite compounds in mint (Mentha arvensis) leaves with an emphasis on alkaloids, flavonoids, tannins, saponins, terpenoids and steroids. The examination strategy uses maceration (watering) techniques for 3 days. Then phytochemical screening was carried out on mint leaves using standard methods. The results showed that the yield of 96% ethanol concentrate from mint leaves was 5.75% and contained a mixture of secondary metabolites of alkaloids, tannins, saponins and steroids.

Abstract

Violces (Viola odorata) have been proven to have many pharmacological benefits as traditional medicine. Its leaves are traditionally used to treat headaches, coughs, colds, bronchitis, and asthma. This study aims to obtain scientific data on the pharmacognostic profile of fresh leaf and fine powder simplisia of violces, as well as to identify the secondary metabolite compounds of the methanol extract of violces leaves. The research method used is a pharmacognostic study (macroscopic, microscopic, and powder microscopy) and phytochemical screening using GCMS and analyzed descriptively qualitatively. Pharmacognostic observations on fresh leaf simplisia showed the presence of fibers, multicellular trichomes, spiral and ladder-type vascular bundles, stomata, covering hairs, and cork tissue. Fragments in the fine powder of violces leaves identified included fibers, multicellular trichomes, spiral and ladder-type vascular bundles, stomata, covering hairs, and stone cells. The results of GCMS analysis of the methanol extract of Violces leaves showed the presence of 27 identified chemical compounds It can be concluded that the pharmacognostic fragments and chemical compounds in this study will help in the identification and standardization of leaves from the Viola odorata species.
