Abstract

Medang wood (Chinnamumum sp) and Bintangur wood (Calophyllum sp) was used for timber construction even they have low quality on the durability. The efforts need to improve their durability, especially against subterranean termites, the most destructive wood organism. One methods of preservation which can improve the durability was fumigation. Fumigation can be processed with traditional methods and modern methods.  The aim of the study was to improve the durability of Medang wood (Chinnamumum sp) and Bintangur wood (Calophyllum sp)with modern fumigation methods and evaluation the durability against subterranean termites Coptotermes curvignathus Holmgren. Wood sample was measured 2 cm x 2 cm x 1 cm. The fumigation treatment was conducted with oven. The oven size was 1 m x 1 m x 50 cm. Treatments of fumigation consits of 12 hours and 24 hours. The treatment of evaluation the durability agaisnt termites was conducted for 21 days. The wood sample was put on the bottle and 50 termites consist of 45 workers and 5 soldiers were put in the wood sample. The parameter of indicator was termite’s mortality and wood weight loss. Result of the research showed that average termites mortality was reach 100% at wood sample with fumigation method for 24 hours, and 89.2% for wood sample with fumigation method for 12 hours. Meanwhile in control wood the termite’s mortality only 8.6%. The level of termites mortality with fumigation methods for 24 hours was classified very strong and for fumigation methods for 12 hours was classified as strong. The average wood weight loss was 1.21% - 1.30%. This wood weight loss was classified as very low. From the research it is concluded that fumigation method can increased the durability of wood, both on Medang wood and Bintangur wood against the subterranean termites Coptotermes curvignathus Holmgren. The optimal fumigation methods was on 12 hours, both on Medang wood and Bintangur wood.Keywords: Calophyllum sp, Chinnamumum sp, Coptotermes curvignathus, fumigation, wood preservation

Abstract

The study uncovers the promising anti-termite properties of Eucalyptus pellita bark extract, a resource often discarded as industrial waste in the pulp and paper manufacturing industry. It investigates the anti-termite efficacy of various extracts from E. pellita bark and identifies the extract with the highest activity, followed by a comprehensive phytochemical analysis. Samples of E. pellita inner bark, outer bark, and mixed bark were ground into 40–60 mesh powder and subjected to extraction using soxhletation techniques with successive extraction in increasingly polar solvents (n-hexane, ethyl acetate, and methanol solvents). The anti-termite activity of these extracts was evaluated using no-choice bioassays to determine the termite antifeedant activity through the weight loss percentage of test samples and the mortality rate of Coptotermes sp. Furthermore, Py-GCMS analysis was conducted on extracts exhibiting the highest anti-termite activity to elucidate their chemical composition. The findings revealed that methanol extracts from all three parts of E. pellita bark exhibited the most potent anti-termite activity against Coptotermes sp., as evidenced by the highest mortality rate (100%) and cellulose paper weight loss of 9.57 ± 6.66 mg. These methanol extracts were predominantly composed of phenolic compounds, particularly condensed tannins, suggesting a potential breakthrough in termite control. The findings indicate that E. pellita bark may be a sustainable and eco-friendly alternative to chemical pesticides for termite control. Furthermore, its utilization may facilitate waste valorization in the pulp and paper industry, thereby supporting environmental sustainability and economic efficiency.

Abstract

Kegiatan pengabdian kepada masyarakat berupa penanaman pohon dan pembersihan sungai adalah upaya dalam melindungi kelestarian sumber daya air. Kegiatan ini dilaksanakan pada 31 Agustus 2024 dan bertempat di Sungai Karang Mumus, Kelurahan Lempake, Samarinda. Pelaksanaan kegiatan ini diawali dengan penanaman 100 bibit pohon dengan jenis yang berbeda dan dilanjutkan dengan pembersihan sampah plastik dan styrofoam. Kegiatan ini berlangsung dengan lancar dan menyebabkan dampak positif terhadap penghijauan Kembali wilayah bantaran Sungai Karang Mumus dan peningkatan kesadaran bagi Masyarakat di sekitarnya.

Abstract

Penelitian ini bertujuan untuk mengkaji dinamika populasi, aktivitas makan, serta laju konsumsi (feeding rate) rayap tanah Coptotermes curvignathus pada pengujian keawetan kayu menggunakan umpan kayu sengon dan kayu karet di laboratorium. Sampel kayu dikondisikan sesuai standar SNI 01.7207-2006 dan diuji selama 6 minggu dengan pengamatan berkala terhadap jumlah rayap hidup, berat kayu, dan aktivitas makan. Hasil menunjukkan bahwa rayap lebih aktif mengonsumsi kayu karet dibandingkan kayu sengon, namun nilai feeding rate tertinggi justru tercatat pada kayu sengon sebesar 61,03 μg/ekor/hari. Mortalitas rayap meningkat signifikan setelah minggu ke-4 dan seluruh koloni diperkirakan mati pada hari ke-57. Berdasarkan penurunan jumlah rayap dan berat kayu, minggu ke-4 ditentukan sebagai waktu pengujian paling efisien. Penelitian ini memberikan dasar ilmiah dalam pengembangan metode uji keawetan kayu yang lebih efisien dan terstandarisasi
