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

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

Salah satu vegetasi yang dijadikan sebagai alternatif dalam revegetasi lahan adalah anaman Trembesi (Samanea saman). Tumbuhan trembesi dapat tumbuh dengan baik jika diberikan unsur hara yang baik yaitu dengan campuran tanah dengan bahan orgnaik. Bahan organik yang berpotensi untuk perbaikan sifat fisik tanah adalah serbuk gergaji. Tujuan penelitian ini dilakukan untuk mengetahui pengaruh pemberian kompos serbuk gergaji gaharu sebagai media tanam dan untuk mengetahui komposisi optimal media tanam kompos serbuk gergaji gaharu terhadap pertumbuhan semai trembesi. Metode pengamatan ini dilakukan dengan memperhatikan persentase hidup, pertambahan tinggi semai dan diameter batang, nilai kekokohan, berat kering total, nisbah pucuk akar dan indeks mutu bibit. Data yang didapatkan kemudian dianalisis sidik ragam secara statistik menggunakan software SPSS versi 17.0. Kesimpulan dalam penelitian ini yaitu bahwa pemberian kompos serbuk gergaji gaharu berpengaruh terhadap persentase hidup, tinggi, diameter, dan kekokohan semai terhadap semai trembesi dan Komposisi optimal kompos serbuk gergaji gaharu terhadap pertumbuhan semai trembesi yaitu perlakuan P3 dimana rata-rata persentase hidup 60%, pertambahan tinggi 2,98 cm, pertambahan diameter 1,13 mm, nilai kekokohan semai 8,46, nisbah pucuk akar 1,56, dan indekd mutu bibit 1,86.

Abstract

Mangrove species exhibit variations in leaf functional traits that reflect differences in resource-use strategies; however, information on the coordination of these traits during the seedling stage remains limited. This study aimed to evaluate leaf functional trait variation among four mangrove species (Avicennia alba, Bruguiera gymnorrhiza, Bruguiera parviflora, and Rhizophora apiculata) by analyzing leaf economic traits, leaf morphological traits, and their interrelationships. A total of 120 seedlings grown under relatively uniform nursery conditions were evaluated. The measured traits included Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC), Aspect Ratio (AR), and Shrinkage Index (SI). Data were analyzed using descriptive statistics, one-way analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT), and Principal Component Analysis (PCA). The results showed that all measured traits differed significantly among species (P < 0.05), with effect sizes ranging from moderate to very large. PCA revealed that the first two principal components explained 73.75% of the total variation in leaf traits, indicating that interspecific variation was driven by the coordination of multiple leaf traits rather than by a single trait. These findings demonstrate that a multivariate approach provides a more comprehensive understanding of leaf functional trait variation among mangrove seedlings.

Abstract

This community service activity aimed to improve the knowledge of residents of Kuala Tolam Village regarding drought control, flood management, peatland ecosystems, and riverbank landslide mitigation in areas vulnerable to hydrometeorological hazards. The education program was conducted through material delivery, discussions, and pre-test and post-test evaluations using a questionnaire. Data were analyzed using IBM SPSS Statistics 20 to describe respondent characteristics and to examine knowledge improvement using a paired sample t-test. The results showed that 66.67% of participants were initially in the low knowledge category; however, after the intervention, all participants improved to the moderate and high categories. The mean knowledge score increased from 47.33 to 69.73, with a statistically significant difference (p 0.05). This improvement was supported by the relevance of the materials, including peatland hydrology, drought control, flood mitigation, and riverbank bioengineering. Participatory education is therefore important for strengthening community capacity and village preparedness in managing environmental risks in peatland ecosystems.
