Abstract

Mangrove is a type of plant that can survive on muddy substrates and at relatively high levels of water salinity. Information about the ecological value of mangrove is very important, in order to provide an overview of the current condition of mangrove. The purpose of this study is to determine the structure of mangrove community in regional marine conservation area Gili Sulat. This study used quadratic transect method measures are 10 m x 10 m (tree category), 5 m x 5 m (sapling category), 2 m x 2 m (seedling category). Based on the results this study obtained 8 true mangrove species and 2 association mangrove species in regional marine conservation area Gili Sulat. Mangrove species that have the highest frequency value is Rhizophora mucronata (0,57 ind/m²) while the lowest is Avicennia marina (0,03 ind/m²). The density for the tree level is in the rare category, while the sapling and seedling levels are in the very dense category. Bruguiera gymnorrhiza and Rhizophora mucronata species had the highest cover values in the tree and sapling category. The highest INP values in the category of tree, sapling, and seedling were 114,93% (Bruguiera gymnorrhiza), 82,32% (Rhizophora mucronata), and 69,87% (Rhizophora mucronata). Dominance index values are classified as low to moderate and the diversity index obtained is moderate.

Abstract

The effect of shallot peel (Allium ascalonicum L.) as a natural growth regulatory substance on root growth of cassava stem cuttings (Manihot utilissima). This study aims to determine the effect of shallot peel extract on root growth of cassava stem cuttings and determine the most effective treatment for root growth of cassava stem cuttings. This study used a completely randomized design consisting of 1 factor, namely the treatment of shallot peel extract concentration which had 10 levels (concentration 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80 %, 90% and 100% of shallot peel extract) and 3 replicates. The variables observed in this study were the number of roots and the longest root length from the roots of cassava stem cuttings. The data obtained were analyzed using the ANOVA test and the HSD (Honestly Significance Different) follow-up test with an error rate of 5%. The results showed that the treatment of shallot peel extract had a significant effect on the root growth of cassava stem cuttings. The most effective concenstration of shallot peel for root number growth was 20%, while for root length growth the most effective concentration was 30%.

Abstract

Seagrass has high productivity so it is said to be a complex shallow marine ecosystem. The role of seagrass ecosystems is very important, especially in terms of ecological and economic functions. The purpose of this research is to reveal the existing condition of the seagrass ecosystem. Data collection used the line transect method with a square measuring 1m x 1m. The sampling technique uses a systematic random sampling method. The results of the study obtained 4 species and 2 families, among others: Hyddrocharitaceae including Enhalus acoroides, and Thalassia hemprichii. The Potamogetonaceae family consists of Cymodocea rotundata, and Syringodium isoetifolium. Seagrass species that have a high enough influence on seagrass ecosystems in Gili Sulat waters are Thalassia hemprinchii, with an important value index (INP) of 184.74, a density value of 65.59% (rather dense status), a frequency of 48.21% (wide enough distribution), and 70.84% coverage (rich/healthy status).

Abstract

This research was used to determine the number of plant species used in traditional medicine, the parts of the plants used, the method of processing, and their properties for treating diseases used by the Sasak Bayan Tribe in Anyar Village, North Lombok. The subjects in this study were the Sasak people living in Bayan, Anyar Village, North Lombok. Respondents in this study consisted of 10 people with an age range of 40-102 years. Techniques in collecting data consists of 3 ways, namely interviews, observation, and documentation. The technique in analyzing data consists of 3 techniques, data reduction, data display, and conclusions. The data information obtained shows that there are 36 species from 26 families that are used to cure diseases in Anyar Village, North Lombok. The parts of the plant used as medicine include flowers, roots, tubers, rhizomes, fruit, leaves, stems, and mucus. There are various ways to process plants as medicine, including boiling, grating, pounding, pressing, cooking vegetables, using directly, squeezing, slicing, anointing, brewing, dripping, smearing, chewing and pasting. Various diseases can be treated by utilizing plants by the Sasak Tribe in Anyar Village, North Lombok which consists of 32 diseases.

Abstract

This research aims to; 1) obtaining a comprehensive and accurate description of the type, composition, and nutritional content of Philemon buceroides food in its natural habitat, 2) the basis for preparing pellets, and 3) input for conservation efforts. Identification and analysis the types of materials that birds eat using a light microscope and a scanning electron microscope (SEM). The composition and chemical content of food nutrients were analyzed using the Kjedhal Gunning Method (AOAC, 1970). As a result, there are two kinds of food for Philemon buceroides, sourced plant parts and insects. Food in the form of plant parts is nectar and fruit from 9 species, 7 species providing food in the form of fruit and two species providing nectar. It eats seven types of insects, that is Diptera, Cryptotympanus accuta, Hymenoprera, Kampi neurobasis, larvae, Orthoptera and Oecophyla samaradigna. The composition and nutritional content of the food consists of 4 types, namely protein 36.8%, carbohydrates 29.6%, fat 20.73%, fiber, vitamin A, vitamin B, vitamin C, and various minerals and water 10 - 76%.

Abstract

Long beans are plants of the Leguminoceae family that grow on vines. Long bean growth rate is influenced by various factors. Some of the external factors that determine the growth rate of long beans are the availability of nutrients and the application of mulch on agricultural land. Research on the vegetative growth response of long bean due to different types of mulch and doses of vermicompost fertilizer has been carried out in Mertak Umbak Village, Central Lombok. This study aims to analyze: (1) the vegetative growth response of long bean due to different types of mulch, (2) the vegetative growth response of long bean due to different doses of vermicompost, (3) the effect of a combination of types of mulch and vermicompost dosage on long bean growth. Research data were analyzed using Anova. The research results show that: (1) the vermicompost treatment significantly affected the increase in total leaf and plant height, but did not have a significant effect on the length and width of long bean leaves, (2) the application of mulch had a significant effect on all observed growth parameters, the highest growth parameters were observed in the application of plastic mulch black silver, (3) the interaction of mulch type and vermicompost dosage had a significant effect on plant height but did not have a significant effect on other growth parameters.
