Abstract

The potential of natural resources and human resources (forest dwellers), occupy the same position in the importance of sustainable forest management. This study aims to determine the socio-economic conditions in order to protection and preservation of the population and habitat of endemic species Hopea celebica and Vatica flavovirens. This study examines some parameters of the social and economy (the level of community participation, the tendency of society to a certain type of behavior on the forest, people's behavior toward the tree species, the public perception of the type of endemic, people's incomes, land for a decent life, use of environmental services, history and culture area of each village). The results showed the Local Wisdom Society is closely linked to the protection and preservation program habitats and populations of endemic species. The level of participation of the two villages, including High. Society has a tendency towards certain commodities namely plant pepper. People's behavior toward forests affected by distance from the house very close to the forest so that almost every day in the woods, with the purpose of hunting, non-wood, wood (for the house, for sale, pole pepper), and gardening / open land. This type of wood is taken is the type that grow, with equipment such as axes, and are used for the manufacture of home. The level knowledge of public about the species endemic to Sulawesi (meranti, rode, and dama'dere) is very low. Welfare level is quite good, and the average land managed by the current wider than the minimum land area for a decent life, and land productivity is high, so the potential for farm expansion does not occur.

Abstract

The low infiltration rate causes most of the rainwater that falls to the ground to become surface runoff, and only a small portion of the water can enter the ground as groundwater storage. The infiltration in the Tandung Billa IUPHKm location includes the use of forest land, shrubs, and mixed gardens, and the management carried out by the community at the Tandung Billa IUPHkm location is the cultivation of agricultural/plantation crops under tree stands in hilly or slightly sloping areas. Land use in the Tandung Billa Community Forest Utilization Business Permit (IUPHKm) consists of forest land, shrubs, and mixed gardens; each land use affects soil and land conditions, which in turn will affect the infiltration rate of the land. Therefore it is necessary to know how the infiltration rate in forest land use, mixed garden shrubs. Measurement of the infiltration rate was carried out by taking soil samples for physical properties, and soil moisture content in three different land uses, namely forest, shrub, and mixed garden land use; the measurement was carried out using a double-ring infiltrometer. The results showed that the infiltration rate on forest land was classified as medium-fast, namely = 83 mm / hour, with clay texture, then the infiltration rate in shrubland was classified as moderate, namely = .62 mm / hour, with clay soil texture and clay. The infiltration rate in mixed garden land/agroforestry is classified as moderate, namely = 53 mm / hour with a dusty clay texture.

Abstract

The ecological feasibility of sago plants is not strong enough to determine sago as a commodity that can be developed in the upstream area. The research objective was to assess the community's perception of the strategy for water of sago land management in Salu Paku sub-watershed, the upper part of Rongkong watershed. The research begins with the socialization of the rainfed sago land water management strategy. The research consisted of two stages (before socialization and after socialization). The results showed that before the socialization, 100% of the community understood that sago land did not need water management, but after socialization, the community understood that sago could be developed in dryland conditions if there was water management. The community previously understood that it was not important to regulate the number of plants in one clump, after receiving additional information, generally, they wanted to regulate the number of sago trees by maintaining two tillers, one weaning plant, and two tillers during the weaning period. phase, and in the tree phase raise one tree plus one wean and two chicks. The public perception of water conservation measures before the socialization was doubtful 100%, after the socialization, the perception increased 95% (willing to make terraces and dead-end trenches), and 5% were still in doubt. Public perception about the addition of organic fertilizer to sago land before the socialization was doubtful 100%, after the socialization, 95% of the people agreed to add organic fertilizer, although 5% still had doubts

Abstract

Land use affects changes in peak discharge so that it has the potential to cause or prevent flooding. Sago has morphological characteristics that have the potential to absorb more water. This study aimed to determine the magnitude of the change in peak discharge in the upstream watershed after sago planting. Observations were made on the three growth phases of sago palms (initial, middle, and mature phases). The research stages included calculating the runoff coefficient value under sago stands at three growth phases. Peak discharge of the existing conditions (settlements, rice fields, mixed gardens, shrubs, sand dunes, forests, and water bodies) was estimated after three scenarios of sago land use. The scenarios consisted of 25% of the land area planted with sago (scenario 1), 50% for scenario 2, and 100% for scenario 3. The data were analyzed quantitatively by comparing peak discharge in the existing conditions with scenario results. The results showed that the peak discharge in the existing conditions was 52.36 m3 hour-1. Peak discharge in the initial phase of scenario 1 was 18.94 m3 hour-1, scenario 2 was 37.88 m3 hour-1, and scenario 3 was 75.77 m3 hour-1. Peak discharge in the middle phase of scenario 1 was 19.01 m3 hour-1, scenario 2 was 38.02 m3 hour-1, and scenario 3 was 76.04 m3 hour-1. Peak discharge in the mature phase of scenario 1 was 6.38 m3 hour, scenario 2 was 12.76 m3 hour-1, and scenario 3 was 26.55 m3 hour-1. The peak discharge in the upstream watershed decreased after the scenarios with the use of sago land for all growth phases, except for scenario 3 of the initial and middle phases.

Abstract

One of the products that can be created from the micro industry is processing palm sap into granulated sugar, commonly known as ant sugar. In the forestry sector, sugar palm is one of the plants included in the category of Non-Timber Forest Products. NTFPs are non-timber forest products that have economic value and benefit many people. This activity aims to determine the capacity of forest farmer groups in processing palm sap into palm sugar using modern technology in the form of crystallite and sorting machines. The methods used are socialization, counselling and using tools for the product packaging. The result of this activity is that public knowledge regarding processing palm sugar using modern technology is still lacking and not used to it. After practising the use of tools accompanied by a team and technicians, community knowledge of the use of modern technology tools in the form of Crystallator and Sorting machines also increased from not knowing to know. Likewise, in terms of product packaging, people who initially used ordinary tools and even used leaves have now expanded to tofu and can use modern packaging tools. However, it is necessary to provide continuous assistance. This activity concludes that the community has been able to use modern tools and package products properly even though they still need help for marketing and stock.

Abstract

Bitti (Vitex cofassus) is one of the most important tree species in Sulawesi, or in some areas, it is also known as gofasa. Bitti wood is also widely used for other uses, such as building timber and carpentry wood. This study aimed to determine the potential source of beetroot (Vitex cofassus) seeds in the Community Forest of Burau Village. This study used the exploratory method by making plots using purposive sampling on a 100m x 100m plot with 38 sampling plots.. Data analysis of potential beetroot seed sources includes measuring diameter, tree height, tillering potential, and determining scoring based on the presence of seeds to determine the possibility of Bitti tree seeds. The results of this study showed that the phenotypic characteristics of the 18 plots that had been selected were a total diameter of 524.44, an entire tree height of 272 m, and a branch-free height of 50.5 m of the 18 parent trees that have been identified, then selected with the criteria of having fruit and saplings. Bitti trees have the most significant tillering potential, found in plot 21 with 0.005% of tillers and 0.0097% of the fruit. Other results obtained the highest value in the parent tree with a score of 73 with a potential class of 5. Genetic and environmental factors can affect plant growth, so the selection of seed source trees to get Bitti mother plants with good phenotypic quality will produce quality seeds.

Abstract

The inflitration capacity is the soil’s ability to accommodate water that seeps into the soil, reducing surface runoff that will cause flooding, such as in the downstream area of Palopo city. This study aimed to determine the influence of dominant vegetation and soil physical characteristics on infiltration in the upstream area of the Latuppa Sub-Das, Mungkajang District, Palopo city. Data collection was carried out by direct observation in the 2yumnaunanda588@gmail.com field in a purposive manner in 10 plots, which represent the condition of vegetation in the upstream area of the Latuppa watershed, and each plot consisted of 3 replications to observe infiltration and soil samples. The data were analyzed via the rational method, the Horton method, and vegetation index analysis. Additionally, the data were analyzed via simple linear regression and multiple regression analysis to determine the influence of the dominant vegetation and physical characteristics of the soil on the infiltration capacity. The highest infiltration capacity was found in plot 10, with an infiltration capacity of 107.5 mm/minute (6,450 mm/hour) and an average infiltration rate of 0.4 mm/minute (24 mm/hour). The dominant vegetation cover is Cananga odorata, with a vegetation index value of 78.41%. Plot 10 has a height of 362.79 masl, a gentle slope, a crumbly soil structure, a clay sand texture, a very high soil density and 2.10% organic matter. Based on observations and data analysis, the factors that influence the infiltration capacity in the upstream area of the Latuppa subwatershed are vegetation conditions, altitude, slope and physical properties of the soil.
