Improving rice productivity requires proper crop management practices, including effective disease control. The objective of this study is to analyze the potential application of Score 250 EC®, with the active ingredient difenoconazole, for the growth of the IR 64 rice variety (Oryza sativa). The experiment was conducted using a Randomized Block Design (RBD) with seven concentration levels, namely S0 = 0 L (control), S1 = 0.075 L, S2 = 0.150 L, S3 = 0.225 L, S4 = 0.300 L, S5 = 0.375 L, and S6 = 0.450 L, where each concentration was diluted in 500 L of water per hectare (ha⁻¹). The 1,000-grain weight parameter showed a significant effect across treatments compared to the control. The treatment with a concentration of 0.300 L Score per 500 L water ha⁻¹ resulted in the highest average weight of 24.78 g. Meanwhile, for the milled dry grain parameter, the concentration of 0.300 L Score per 500 L water ha⁻¹ produced the highest average yield of 7.21 t ha⁻¹

Lung Anai Village, located in the mining buffer zone of Kutai Kartanegara Regency, experiences complex livelihood dynamics due to coal mining activities affecting economic, social, and environmental dimensions. This condition highlights the need for a development approach that emphasizes sustainable livelihoods beyond economic growth. This community service program aims to strengthen community capacity using the Sustainable Livelihood Approach (SLA). A participatory, community-based method was applied through three stages: initial assessment, program implementation, and evaluation. The results show that social, physical, and financial capital are relatively strong, while human and natural capital remain lower, indicating structural imbalance. Community perception improved significantly from 37% positive responses in 2023 to 100% in 2024, reflecting increased trust. The Social License to Operate (SLO) index reached 77.2%, indicating strong social acceptance. The program enhanced participation, strengthened institutions, improved economic access, and promoted sustainable livelihoods. The SLA approach proved effective and replicable for empowering mining-affected rural communities.

Peningkatan produktivitas padi memerlukan upaya pengelolaan budidaya yang tepat, termasuk pengendalian penyakit. Penelitian ini bertujuan untuk menganalisis potensi aplikasi Score 250 EC berbahan aktif Difenokonazol terhadap pertumbuhan padi varietas IR 64 (Oryza sativa). Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) dengan 7 taraf konsentrasi perlakuan, beberapa konsentrasi tersebut yaitu S0 = 0 L (kontrol), S1 = 0,075 L, S2 = 0,150 L, S3 = 0,225 L, S4 = 0,300 L, S5 = 0,375 L, S6 = 0,450 L, yang mana masing-masing konsentrasi berada dalam 500 L air ha-1. Parameter yang diamati meliputi tinggi tanaman, jumlah anakan, jumlah anakan produktif. Hasil penelitian menunjukkan bahwa aplikasi Score 250 EC memberikan pengaruh terhadap peningkatan tinggi tanaman pada umur 50 HST, 67 HST, dan pada saat panen. Pada parameter jumlah anakan produktif menunjukkan pengaruh nyata antar perlakuan dibandingkan kontrol. Perlakuan konsentrasi optimum pada konsentrasi 0,450 L Score/500 L air/ha, menunjukkan pertumbuhan vegetatif yang lebih baik. Peningkatan nilai pada parameter pertumbuhan vegetatif seiring meningkatnya konsentrasi ZPT menunjukkan masih adanya potensi peningkatan parameter petumbuhan dengan penambahan tingkat konsentrasi. Disimpulkan bahwa Score 250 EC berpotensi meningkatkan pertumbuhan vegetatif padi varietas IR 64 pada konsentrasi 0,450 L Score/500 L air/ha.

The red flour beetle, Tribolium castaneum (Herbst.) (Coleoptera: Tenebrionidae), is a secondary pest that commonly attacks products in storage warehouses. Plant-based insecticides derived from local knowledge, such as those used by the Dayak tribe. The use of Shorea macrophylla by the Dayak tribe offers an environmentally friendly approach to pest control. This study was conducted to evaluate the insect repellent activity of the fumigant extract of S. macrophylla with ethyl acetate solvent against T. castaneum. This study consisted of five treatment concentrations, the treatment concentrations used were 30 μL, 60 μL, 90 μL, 120 μL, and 150 μL. Observations were made at six different times, ranging from 60 to 360 minutes. Each treatment was repeated five times and arranged with a Randomized Block Design. The repellent test was carried out using a Y-Tube olfactometer. The results showed that the repellent index increased with increasing concentration and exposure time. After 360 minutes of exposure, the lowest repellent index was 9.4% at a concentration of 30 μL, while the highest percentage was 65.8% at a concentration of 150 μL. This study shows the potential of S. macrophylla extract with ethyl acetate solvent as a botanical pest repellent that is quite effective in repelling T. castaneum.
