Abstract

Acacia crassicarpa is one of the Fabaceae family which has been widely recommended for planting in the context of rehabilitation of critical lands as well as HTI development, due to its fast growth, wide adaptation, and resistance to unfavorable conditions. Acacia crassicarpa in the nursery is often attacked by various pests, one of which is the Paracoccus marginatus. Efforts to the use of Annona muricata leaf control Paracoccus marginatus currently carried out generally use chemical methods. extract is an alternative that can be used as an environmentally friendly pesticide. This study aims to determine the utilization of Annona muricata leaf extract to control Paracoccus marginatus in Acacia crassicarpa nursery and to determine the best concentration of Annona muricata leaf extract for the mortality rate of Paracoccus marginatus. This study used a completely randomized design method (CRD) consisting of 4 treatments and 4 replications with concentrations of vegetable pesticide solutions. P0 = control (without Annona muricata leaf extract), P1 = 10 g/l of water, P2 = 20 g/l of water, P3 = 30 g/l of water. The results showed that the botanical pesticide from Annon muricata leaf extract concentration of 30 g/l of water is the best concentration in controlling Paracoccus marginatus with the fastest initial time of insect death is 2.5 hours (2 hours 30 minutes), 50% fastest time of death (LT50) is 8.5 hours (8 hours 30 minutes) and total mortality amounted to 90 %.

Abstract

Cellulase enzymes are widely used in textile, food, detergent, pulp and paper industries and biofuel, so the need for enzymes continues to increase every year. One of many biomass wastes found in Indonesia is empty fruit bunches (EFB) that can be used as a carbon source as a substitute for expensive pure cellulose (CMC) and Bacillus subtilis isolates. This study aims to obtain the optimum conditions the production of cellulase enzymes with variations in the pre-treatment of EFB and pH variations of the medium using Bacillus subtilis. Pre-treatment was carried out to hydrolysed lignocellulosic biomass was more easily and increased glucose levels which would enter the next production stage. Variations in pre-treatment were carried out by adding acids, bases and organosolv process, as well as variations in pH at 6.5; 7.0 and 7.5, respectively. Enzyme activity was calculated using the Nelson-Somogyi method. When using acid, the enzyme activity is 0.041, while using organosolv, it is obtained 0.057 each at pH 7. The results showed that the highest enzyme activity was obtained at a pH of 7.0 and a temperature of 40 ºC on EFB substrate pretreated with a base of 0.204 U/ml. These findings emphasize the potential benefits of using EFB waste as a substrate for cellulase enzyme production, by providing an alternative approach to decrease raw material expenses and mitigate environmental pollution.

Abstract

Management actions through rehabilitation activities can restore mangrove ecosystems by involving community participation. This study aims to determine the involvement and effectiveness of community-based rehabilitation activities. This study was conducted in Teluk Pambang Village, Bengkalis Regency. The method used is qualitative, with a purposive sampling technique based on certain criteria. The data analysis used is qualitative descriptive and data processing using nvivo 12 plus software. The research findings explain that the dominant factors that encourage people to carry out mangrove rehabilitation activities are based on additional income, strengthening the issue of carbon trade economy, kinship elements, and easy access to financing through donors. The level of program understanding, target accuracy, activity management, and real changes are the most effective rehabilitation activities for the community. At the same time, the indicators for achieving goals are still considered ineffective.

Abstract

Background: Acacia is a top priority plant in developing industrial forest plantations, especially in Sumatra, because it meets the requirements as raw material for the pulp and paper industry. PT. Sekato Pratama Makmur (SPM) is a company that cultivates this plant. Constraints often encountered in developing pulpwood plantations include pests, diseases, and seedlings that fail to adapt to the field. It is essential to analyze the health of acacia seedlings in the PT. SPM nursery, as a basis for pest and disease control and plant protection measures. This study aims to determine the intensity of pest and disease attacks and the health condition of acacia plants. Methodology: The scoring method used in this study was used to determine the attack score on acacia seedlings. Data from this study were analyzed descriptively and quantitatively using the formulas of survival rate, intensity of pest and disease attack, and percentage of health. Findings: The results showed that the percentage of pest and disease attack intensity was 1.90% in sowing 1, 6.16% in sowing 2, and 5.88% in sowing 3, with mild damage. The percentage of acacia plant health was 95.10% in sowing 1, 89.38% in sowing 2, and 89.20% in sowing 3. Damage to leaves included leaf curling, leaf holes, leaf yellowing, leaf spots, and blight. This indicates that the acacia seedlings in the nursery are in good condition. The low intensity and minor severity of pest and disease attacks demonstrate that the control measures implemented by PT. SPM are effective. Contribution: This research contributes to the development of effective pest control strategies by providing initial information on the health condition of acacia seedlings and supports the long-term success of field planting.
