Abstract

The existence of mangrove vegetation in Bangkir Village, Dampal Selatan District, Tolitoli Regency has decreased due to the conversion of mangrove forests into ponds. This study aims to determine the structure and composition of mangrove species in the village of Bangkir. This study uses two methods, namely the qualitative descriptive method through the survey method and the line transect method. Determination of the transect line amounted 1 line and plot placement by purposive sampling amounted to 6 plots. Parameters salinity, pH and soil texture. Data analysis was performed by calculating the relative density, relative frequency and relative dominance to obtain the Importance Value Index (IVI). The results showed that the forest structure consists of three layers, namely layer C and D which are dominated by Avicennia marina, layer E is dominated by Bruguiera cylindrica, while the type Sonneratia alba does not dominate the three layers. The composition the types of constituents are 3 types of mangroves and 3 families. The species that had the highest Importance Value Index (IVI) at all growth stages trees, saplings and seedlings was Avicennia marina and the lowest was Sonneratia alba. The growth salinity level Avicennia marina species has a salinity of 38%, then a pH of 5.14-6.18, the soil texture is a dusty clay substrate, the Sonneratia alba species has a salinity level of 33%, a pH of 5.20-6.62, the texture of clay sand, and Bruguiera cylindrica species have a salinity level of 26%, pH 6.17-7.23, texture of clay substrate.Keywords: Structure, Composition, Mangrove

Abstract

Forests are one of the natural resources that have important meaning for human life. Forests with various functions and benefits have a very large influence both directly and indirectly on ecological, economic and social aspects. The purpose of this study was to determine the value of the diversity of plant species that make up the vegetation. This study uses the observation plot/plot method to see the diversity of the types of vegetation constituents in the Protected Forest Area of Uwemanje Village, Kinovaro District. The Important Value Index is used to determine the dominance of one species over another in a stand. Significant values were obtained from the sum of the Relative Density (KR), Relative Frequency (FR) and Relative Dominance (DR) for the level of stakes, piles and trees. The species diversity index was used to determine the species diversity of forest stands. Based on the results of research that has been carried out the types of plants that make up the vegetation in the protected forest area at the tree level found 16 species of trees from 14 families, at the pole level found 16 species from 16 families, at the sapling level found 10 species from 9 families, and at the seedling level found 10 types from 9 families. The level of Species Diversity (H¹) for each level is at the tree level H¹ = 3.81. Pile level H¹ = 3.35. The sapling level H¹ = 3.45 and at the seedling level H¹ = 3.54 belong to the high criteria.Kata Kunci: hutan, vegetasi, keanekaragaman jenis

Abstract

Maholo Village is one of the villages in East Lore District, Poso Regency, located at an altitude of 1000-1700 meters above sea level. This village is suitable for coffee plantation development activities. However, the development of coffee plants is hampered due to low soil fertility. One way to overcome this problem is by adding organic matter. The addition of organic matter to the soil is known to contribute nutrients that can increase soil fertility, improve the chemical, physical and biological properties of the soil. The lack of public knowledge about this is the goal of conducting counseling activities regarding the benefits of organic materials and their processing technology. The results achieved from this activity are that community service gains knowledge and understanding of the function of organic matter on soil fertility and the community is able to carry out the manufacture and application of organic fertilizers, both independently and in groups.

Abstract

Babyrousa togeanensis is an endemic wildlife of Sulawesi Island, Indonesia. Government development programs and the increased activities of local communities in the Togean Islands National Park area are causing this animal habitat to be narrowed. Monitoring the Babyrousa togeanensis population is crucial to updating their numbers in protected areas to avoid extinction. This study used direct and indirect observation methods to investigate the Babirusa population at Urulepe Point, Togean Island. Our study showed that the total population of Babirusa individuals in the study coverage area was 58 individuals per km2, higher than the number reported in the previous year. The increase in the number of Babirusa populations can be assumed to have occurred due to increased awareness of local people about the importance of protected wildlife, as well as a piece of evidence that conservation by the government through the TNKT has been successfully implemented. Environmental conditions in TNKT are good enough to support the habitat and needs of life and breeding of Togean Babirusa. The most effective method of monitoring Babirusa was camera traps because the wildlife avoids humans, making the direct transect strip method less effective for encountering Babirusa.

Abstract

The aim of this study is to assess the mangrove habitat condition in Mapane Village, Poso Coastal District, Poso Regency. Field surveys were conducted to determine representative mangrove habitat conditions (physical and chemical) in Mapane Village. Soil and water samples were collected to assess mangrove habitat conditions, using purposive sampling method with 3 repetitions. The soil and water quality in the research area is still conducive for mangrove growth, with suitable soil texture for Rhizophora sp. and stable salinity at 34‰. Although soil pH is slightly below standard, it remains suitable for mangrove growth (pH 6-7). Water quality parameters approach quality standards, albeit some below, remaining productive according to previous studies. The optimal pH for mangrove growth is neutral (pH 6.6-7.5). In conclusion, the soil and water quality in the research area strongly support mangrove growth. Despite slightly below-standard soil pH, it remains suitable for mangrove growth. Previous studies indicate the optimal soil pH for mangroves ranges from 6-7, while water pH approaches quality standards, remaining productive despite some below, and below pH levels.

Abstract

Moringa plants have high ethnobotanical value for the Kaili tribe in Porame village, Kinovaro district, Sigi Regency, Central Sulawesi. In this village, some MSMEs focus on producing organic moringa leaf products. However currently facing some problems, for example; the production of organic moringa leaves is still low both in terms of quality and quantity, and availability of raw materials for organic moringa leaves is still lacking due to the absence of moringa cultivation. Therefore, the empowerment program aims to find solutions to solve that problem. The approach method used in the form of education and training for partners by using counseling, training, and assistance methods in the form of technical guidance and community development in the production process of moringa leaves and their cultivation from seed to harvest, as well as the manufacture of organic fertilizers made from livestock manure. The results of the program that have been carried out are that there are organic moringa plantations covering an area of 0.5 Ha, products of organic moringa flour, etc, 20 sacks of organic fertilizers, and increasing in the knowledge and skills of farmer group members, especially in terms of organic moringa cultivation, post-harvest handling and diversification of its products.
