Abstract

Phytophthora sp. are pathogenic fungi that can cause plant diseases with symptomatic rotten or known as stem base rotten disease (BPB). Acacia leaf (Acacia mangium Willd.) has secondary metabolite content so that it can be used as a source of natural antifungal substitutes for synthetic antifungal This study uses a completely randomized design (CRD) with 4 treatment levels consisting of control, extract concentration of 2 %, 3 %, and 4 %. Antifungal activity test uses food poisoning method by adding acacia leaf extract to PDA media. The results showed that the extract of acacia leaves (Acacia mangium Willd.) had an effect on inhibiting the growth of isolate Phytophthora sp. (Im5) with the decrease of fungi colony diameter. Concentration of 4 % extract is the best concentration with the very strong level of antifungal activity in inhibiting the growth of Phytophthora sp. (Im5).

Abstract

Cycloseris vaughani is a mushroom coral from the stony coral group (Scleractinia). It is usually found free-living or colony-formed. C. vaughani can adapt to the environment through differences in body size that varies in each individual. The research aims to determine the variations in body size of C. vaughani in Kabung Island waters. Data were collected by using the belt transect method at 3 research stations. The average body size of C. vaughani individuals shown from 3 research stations was 1.1±3.7 cm, 7.1±1.3 cm and 6.3±1.2 cm. There was a significant difference in body size of the mushroom coral C. vaughani in Kabung Island waters.

Abstract

The cultivation of Namalycastis rhodochorde nypa worms is still experiencing obstacles due to the high mortality rate of larvae, which can be caused by unsuitable conditions for the maintenance media. This study aims to obtain data on the conditions of environmental factors during larval rearing in the laboratory. This study observed environmental factors in 5 larval rearing treatments, namely 50, 100, 150, 200, 250 individuals/L with the size of the rearing tub (37×26×14 cm3). During rearing larvae are given 0.3×10-3 Chlorella vulgaris feed and fermented palm fronds. Data were collected every 10 days for 3 months. The parameters for observing environmental factors were water pH, water temperature, air temperature and salinity.  The results showed that the average water pH was 7.6 with a range between 7.3-7.9, an average water temperature of 25.6 °C with a range between 24-28 °C, an average air temperature of 25.9 °C with a range between 24-29 °C, and the mean salinity of 13.7 ppt with a range between 13-16 ppt. The results of the research on water quality during maintenance were relatively standard, thus supporting survival and growth of N. rhodochorde nipah worms.

Abstract

Hortaea werneckii is a fungus causes of tinea nigra. Plants that are known to have antifungal compounds are bay leaves (Syzygium polyanthum). This study was aimed to determine the best concentration of the methanol extract from bay leaves (S. polyanthum) can inhibit the growth of Hortaea werneckii (T1) in vitro. This study used a completely randomized design (CRD) with treatment levels that consisted of concentrations of 20, 25, 30, 35 and 40%, negative control (sterile distilled water) and positive control (ketoconazole 2%). The antifungal activity test was carried out using the Kirby-Bauer method. Based on the results study showed that concentration 30% is the best concentration in inhibit fungal growth Hortaea werneckii (T1).

Abstract

Shorea leprosula has high economic and ecological value. Shorea leprosula population decreases due to increased illegal logging activities, especially in Gunung Palung National Park. This research aims to find out the density and spreading pattern of Shorea leprosula Miq. at Research Stasiun Cabang Panti, Gunung Palung National Park, West Kalimantan. The research was conducted from June to August 2020. The research method used is random sampling in 3 different locations, namely alluvial habitats, sandy rocks and freshwater swamps. Sampling using a squared method with a plot size of 20 x 20 m and made 10 plots on each habitat. The results showed that the density of S. leprosula is highest in freshwater swamp habitat of 170 individuals/Ha and the lowest in sandy rock habitat of 103 individuals/Ha. Spreading pattern S. leprosula is aggregate.

Abstract

The black nypa worm (Namalycastis cf. terrestris) has not been widely used as an object of research, but its habitat in mangrove waters has been converted into agricultural land and tourist attractions. The purpose of the study was to obtain data on the distinguishing morphological characteristics of the black nypa worm Namalycastis sp. with other Namalycastis worms in the same habitat. Sampling was carried out 12 times for 3 months with a total sample of 68 worms consisting of 8 male individuals, 58 female individuals, and 2 juvenile individuals. The morphological characters measured included color, body length and weight, parapodia type and setae type which were then analyzed by t-test. Black nypa worm N. cf. terrestris is blackish green with a body length of 15,2-57 cm and a weight of 1,18-16,25 g. The prostomium has a pair of palps and the peristomium is equipped with 4 pairs of peristomial features and a pair of jaws. Parapodia of sub-biramous type without notopods. Setae N. cf. terrestris is golden brown with black acicular. Notopodial setae consist of sesquigomph spiniger, supra-neuroacicular setae consist of sesquigomph spiniger and heterogomph falsiger, and sub-neuroacicular setae which are heterogomph spiniger and heterogomph types. Black nypa worms are distinguished from other worms in the same genus and habitat only by body color.

Abstract

The Malay people stilluse various types of plants as traditional medicine for the treatment of mothers before and after childbirth.The purpose of this study is to find out the types and parts of plants that are most widely used for the treatment of mothers before and after childbirth. This research was conducted from September to December 2020 in Sekura Village Sambas Regency. Determination of respondents using purposive sampling method. The results of the study obtained 38 types of plants classified in 21 families. The most widely used family is the family Zingiberaceae at 13%. Prenatal treatment is done pregnant 7 months until the end of the process of childbirth, namely drinking potions and pregnant bath ingredients. Traditional postnatal medicine is carried out for 44 days consisting of internal and external medication. The internal medication consists of herbs, sireh untalan, and sambal lade. The external medication consists of abdominal param, body param, bathing material and massage oil. These traditional drugs were taped, eaten, drink and applied as an ingredient for bathing. The most plant part in medicine is the leaves by 27% and the least is the stem by 2%.

Abstract

Water mimosa (Neptunia oleracea L.) is one of the aquatic plants (Leguminoceae) which had adaptive capabilities on water environment was exposed by heavy metal. This research purposed to know the morphology responses, biomass and chlorophyll contents of water mimosa (Neptunia oleracea L.) in water exposed by HgCl2. This research used Completely Randomized Designed (CRD) with 4 levels of HgCl2 treatment such as: control (A), 75 ppm (B), 150 ppm (C), and 225 ppm (D). The experimental plants used was N. oleracea L. from the treatment of HgCl2 concentrations give effects on morphology, biomass and chlorophyll contents, such as: chlorophyll a, chlorophyll b, total chlorophyll. N. oleracea showed the change of color, leaves become yellow, stems are thinner, brownish-look root with soft textures and curled up. The concentration of HgCl2 225 ppm, biomass of N. oleracea L, occurred decrease until 81.93%, and chlorophyll contents of N. oleracea L. occurred decrease until 93.11%.
