Abstract

Jeneberang watershed is one of the watersheds in the MAMMINASATA area (Maros, Makassar, Sungguminasa and Takalar). The watershed, upstream, is now in a critical condition. This study aims to identify and map land use patterns, carbon stock emissions, both in the present condition and after rehabilitation condition. The data and information used in this research are Landsat 7 ETM+ in 2006 and 2010, the Jeneberang watershed boundary map, critical land map, forest area map, rainfall data, population data, and land capability class map. The method used is the interpretation of land use or land cover, biomass calculation, and analysis with REDD ABACUS. The results showed that land use was dominated by plantations and then followed by low density forest, agricultural dry land, rice fields, water bodies, plantation forests, vacant land, shrubs, settlements, high density forests, and savannas. The direction of land cover/land use that can increase carbon sequestration is the conversion of barren land, shrubs and savannas into plantation forests and agroforestry. Potential carbon stocks for plantations, dry land agriculture and rice fields will increase to 2.295.626,32 tons in 2026.

Abstract

Wood industry waste in Indonesia is very abundant, the percentage based on yield produced can reach 50% for sawdust, 70% for plywood industry waste, and 70% of forest harvesting waste. Wood pellets can be an alternative energy source and the availability of raw materials is very easy to find. Wood pellets are the main concern at this time because of the ease of use in raw materials and have environmentally friendly characteristics. The aims of this research was to investigate the characteristic of wood pellets from three types sawdust of wood waste from furniture industry on Palangkaraya city and compare the propreties of wood pellet with Indonesian National Standard (SNI 8021: 2018). This study used material from the sawdust waste of benuas (Shorea laevis Ridl), melur (Dacrydium spp), and jelutung rawa (Dyera polyphylla). Particles from those materials were made on 40-60 mesh, and to reduce the of extractive substances, the particles were extracted in hot water at 100°C for 3 hour. Pellets are made using single-pelletizer at room temperature with a pressure of 30 MPa for 4 hour. The target density of wood pellet was 1 g/cm³ with a diameter was 0.9 cm and length weas 4.5 cm. The results showed that the quality of Benuas, Melur and Jelutung Rawa wood pellets based on SNI 8021: 2018 wood pellet quality standards showed that the testing of wood pellets in general met the Indonesian National Standards except density. Based on the characteristics of the three types of sawdust waste studied based on specific gravity that the type of wood pulp with medium density as raw material for wood pellets that have the best quality because it has a lower water content of 3.72%, higher density 0.75 g / cm3, lower ash content 0.6%.

Abstract

Acclimatization is an indicator of success in tissue culture techniques. Without acclimatization, the plant will remain in the bottle and have no value. Acclimatization is the transfer of plantlets from the microenvironment (in the bottle) to the external environment (soil, sand). The dendrobium orchid is a very popular type of orchid traded, but its growth rate is slow. Atonic ZPT and root most are ZPT which contain a lot of auxin. The purpose of the study was to compare the types and concentrations of PGR that were appropriate for the acclimatization of Dendrobium orchids in order to increase plant growth. The study was conducted experimentally using a non-factorial Completely Randomized Design (CRD) consisting of 7 treatment levels. The levels of treatment were as follows: control, atonic PGR 2 ml/l, atonic PGR 3 ml/l, atonic PGR 4 ml/l, PGR root most 2 ml/l, PGR root most 3 ml/l, and PGR root most 4 ml/l. Each treatment level was repeated 9 times. The results showed that giving atonic PGR and root most had a significant effect on the variables of plant height increase, leaf number increase and primary root length increase and had no significant effect on the increase in stem diameter. The best results were shown by giving atonic PGR at 3 ml/l in all variables except for the increase in primary root length, which was indicated by the treatment with PGR root at most 3 ml/l.
