Daftar Isi:
- Pembibitan kakao (Theobroma cacao L.) merupakan salah satu upaya untuk mempertahankan agroforestri dan menjaga fungsi hutan. Penelitian bertujuan menganalisis kombinasi antara jamur endomikoriza, kompos, dan Trichoderma spp. terhadap pertumbuhan bibit kakao serta menentukan konsentrasi yang terbaik untuk meningkatkan pertumbuhan bibit kakao. Penelitian dilakukan di laboratorium taksonomi tumbuhan (mikologi) dan green house Persemaian Permanen Suwung, Badan Pengelolaan Daerah Aliran Sungai dan Hutan Lindung Hutan Anyar. Perlakuan disusun secara RAK (Rancangan Acak Kelompok) dengan 5 perlakuan yang terdiri dari 5 ulangan dan 3 unit tanaman untuk setiap ulangan. Perlakuan pertama menggunakan tanah steril (kontrol negatif), perlakuan kedua dengan tanah steril + kompos 10 g + Trichoderma spp 10 mL (kontrol positif), perlakuan ketiga dengan tanah steril dan inokulasi endomikoriza Glomus sp 100 butir + kompos 10 gram + Trichoderma spp. 10 mL, perlakuan keempat dengan tanah steril dan inokulasi endomikoriza Glomus sp 150 butir + kompos 10 g + Trichoderma spp. 10 mL, dan perlakuan kelima dengan tanah steril dan inokulasi endomikoriza Glomus sp 200 butir + kompos 10 g+ Trichoderma spp. 10 mL. Hasil penelitian menunjukkan bahwa perlakuan kelima (200 spora endomikoriza, 10 mL Trichoderma spp., dan 10 g kompos) merupakan kombinasi terbaik untuk pertumbuhan bibit kakao dilihat dari nilai parameter tinggi tanaman sebesar 29,03 cm, berat kering tanaman 3,55 g, berat kering akar 1,83 g, dan persentase kolonisasi endomikoriza sebesar 6,33 %.

- Quality of cacao seedlings (Theobroma cacao L.) is one of the effort to maintain agroforestry and forest functions. This study aimed to identify the effects of the endomycorrhizal spores, compost, and Trichoderma spp. for cacao seedlings and to investigate the best concentration of media combinatioins on growth of cacao seedlings. The study was carried out in plant taxonomy laboratory (mycology) and the green house of Suwung Permanent Nursery, BPDASHL. Treatments were set up on RCBD (Randomized Complete Block Design) with five treatment combinations and 5 replications and 3 units of experiment. The first treatment was application of sterile soil only (negative control), the second treatment was with sterile soil+10 g of compost+10mL of Trichoderma spp (positive control), the third treatment was sterile soil+100 spore of endomycorrhizal Glomus sp. +10 g of compost+10mL of Trichoderma spp, the fourth treatment was with sterile soil+150 spore of endomycorrhizal Glomus sp. +10 g of compost+10mL of Trichoderma spp, and the fifith treatment was with sterile soil+200 spore of endomycorrhizal Glomus sp. +10 g of compost+10mL of Trichoderma spp. The result showed that combination of the fifith treatment (sterile soil+200 spore of endomycorrhizal Glomus sp. +10 g of compost+ 10mL of Trichoderma spp.) was the best combination cacao seedlings for plant heights (29,03 cm), plant dry weight (3,55 g), root dry weight (1,83 g), and the percentage of endomycorrhizal colonization (6,33%).
