Abstract

Mining activities affect the balance of the soil surface ecosystem, decreasing soil productivity which causes the chemical, biological, and physical properties of the soil to be disturbed, as well as environmental quality. The purpose of this study was to determine the effect and the best composition of a mixture of compost and former gold mine soil in the growth of suren seedlings. This study consisted of 4 (four) treatments and 5 (five) replications resulting in 20 experimental units. The treatment of compost fertilizer in this study can be seen as follows: D1 = no compost/control, D2 = 25% compost + 75% ex-gold mine soil, D3 = 50% compost + 50% ex-gold mine soil, D4 = 75% compost + 25% ex-gold mine soil. The observation parameters are the percentage of life, height increase, plant dry weight and seedling quality index (IMB). The results showed that the application of goat manure compost had a significant effect on the growth of suren seedlings. Treatment composition D4 (75% compost fertilizer + 25% gold mine waste soil) showed the best growth with 100% survival rate, 21, 27 cm height increase, 10.57 g plant dry weight and 0.99 IMB

Abstract

The lack of land preparation and trash bins in Pulau Kalimanting Village is one of the problems that has occurred so it is necessary to evaluate the prevention of problems that occur so as not to cause diseases that will make people sick. The purpose of this Kuliah Kerja Nyata (KKN) is to find solutions related to environmental pollution problems found in Pulau Kalimating Village at this time. Some of these places are at the State Elementary School 013 Pulau Kalimanting Village, Posyandu, and Lane House. Because of these problems, the right solution is to procure a trash can as a form of implementation to reduce the dirty environment in Pulau Kalimating Village. This report will describe how the trash can functions for the village community so that with these efforts it is hoped that it can increase public awareness about the importance of environmental cleanliness and understand the concept of sorting organic and anorganic waste. The method used is by directly handing over the bins to the school principal, the head of the posyandu, and the lane chairman who will later use the bins properly. This activity was well received and enthusiastic by the community because it was considered as an effort to improve environmental cleanliness in Pulau Kalimanting Village. Thus, this activity is quite effective in overcoming waste piles.

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.

Abstract

The decline in productivity of Acacia seedlings (Acacia crassicarpa) in Industrial Plantation Forests is caused in part by attacks of mealybug pests (Paracoccus marginatus). Using chemical insecticides in pest control can negatively impact health and the environment, so more environmentally friendly alternatives are needed, such as plant-based insecticides. This study aims to determine the concentration of noni leaf extract on the mortality of mealybug pests. A completely randomized design (CRD) was employed, consisting of four treatments with different concentrations of Morinda citrifolia leaf extract (30 g/l, 40 g/l, 50 g/l, and 60 g/l), each replicated three times. The observed parameters included the time of initial death, Lethal Time 50 (LT₅₀), and total mortality percentage. The results indicated that the use of Morinda citrifolia leaf extract of 60 g/l was the most effective, with an average time of 8,67 hours, LT₅₀ of 24,67 hours, and total mortality rate of 100% for Paracoccus marginatus.
