Penyakit busuk pangkal batang merupakan penyebab kerugian paling besar pada tanaman kelapa sawit dibandingkan dengan organisme penganggu tanaman (OPT) lainnya. Penyakit tersebut disebabkan oleh cendawan patogen Ganoderma boninense. Upaya pengendalian infeksi G. boninense menggunakan Agen Pengendali Hayati (APH) merupakan metode yang paling baik karena bersifat efektif, efisien, ramah lingkungan dan berkelanjutan. Agen Pengendali Hayati (APH) merupakan organisme yang dapat digunakan untuk keperluan pengendalian hama dan penyakit atau organisme pengganggu tumbuhan (OPT) dalam proses produksi dan pengolahan hasil pertanian. Cendawan tanah dan endofit diketahui memiliki kemampuan antagonis terhadap G. boninense, sehingga berpotensi dimanfaatkan sebagai APH untuk tanaman kelapa sawit. Isolat cendawan tanah dan endofit diisolasi dari sampel tanah dan akar tanaman kelapa sawit dengan metode spread plate pada media PDA (Potato Dextrose Agar). Isolat cendawan tersebut kemudian diuji keamanan hayati menggunakan benih mentimun dan padi, sehingga diperoleh 18 isolat bersifat nonpatogen yang tidak menimbulkan gejala kerusakan pada benih dan kecambah uji. Penelitian dilanjutkan dengan uji antagonis isolat cendawan terhadap G. boninense secara in vitro, dan diketahui 12 isolat cendawan mampu menghambat pertumbuhan G. boninense. Dari penelitian ini diperoleh enam isolat cendawan yang memiliki kemampuan daya hambat terhadap G. boninense di atas 50% yaitu CE-8: 53,5%; CR-16: 61,5%; CR-1:61,9%; CE-3: 64,0%; CR-10: 65,2%; dan CE-4: 85,1%. Enam isolat cendawan tersebut merupakan isolat yang berpotensi digunakan sebagai APH untuk tanaman kelapa sawit.

Asparagus beans (Vigna unguiculata subsp. Sesquipedalis) have high economic and nutritional potential, but their yield has declined due to suboptimal land fertility. Inorganic fertilizers pose adverse influence on the environment, so more eco-friendly organic materials, such as coffee grounds and rice husk ash are necessary. This study aims to evaluate the effect of coffee grounds and rice husk ash on the growth and production of asparagus beans. It was conducted in the experimental garden of the Faculty of Agriculture, Universitas Borneo, Tarakan City, using a Randomized Block Design (RBD) with five treatments: no coffee grounds and rice husk ash (P0), 1.5 ton/ha of coffee grounds (P1), 4 ton/ha of rice husk ash (P2), 0.75 ton/ha of coffee grounds + 2.0 ton/ha of rice husk ash (P3), and 1.5 ton/ha of coffee grounds + 4 ton/ha of rice husk ash (P4). The results corroborated that using 1.5 ton/ha of coffee grounds (P1) yields the highest outcome with respect to plant height (113.4 cm), the number of leaves (38 strands), the number of pods to the control (4 pieces), the length of the pods (4.01 cm), and the weight of the pods (140.65 g), compared to other treatments and control. Coffee grounds are proven a more effective material than its combination with rice husk ash in elevating the growth and yield of asparagus beans in red-yellow podzolic soil.

Cendawan merupakan mikroorganisme eukariotik yang dapat terbawa oleh benih padi dan bersifat patogenik, menurunkan kualitas, daya tumbuh, dan hasil panen. Spora atau hifa cendawan dapat bertahan dalam kondisi dorman pada benih. Identifikasi morfologi seperti warna koloni, hifa, dan konidia penting untuk deteksi awal. Penelitian ini bertujuan mengidentifikasi morfologi cendawan terbawa benih padi di Kalimantan Utara sebagai dasar pengendalian penyakit sejak tahap perbenihan. Penelitian dilakukan di empat kecamatan sentra padi Kalimantan Utara: Tanjung Selor, Tanjung Palas, Tanjung Palas Tengah, dan Tanjung Palas Utara pada tahun 2020 menggunakan metode snowball sampling hingga mencapai 75% petani. Dari tiap responden diambil 200 gram benih padi. Deteksi cendawan menggunakan blotter test dan diinkubasi selama satu minggu. Identifikasi dilakukan dengan mikroskop stereo (400x dan 1000x) berdasarkan hifa dan konidia. Kabupaten Bulungan, Kalimantan Utara, merupakan sentra produksi padi dengan 14 varietas benih yang digunakan petani. Dari sampel benih di empat kecamatan, ditemukan empat genus cendawan, yakni Alternaria, Aspergillus, Mucor, dan Rhizopus. Cendawan tersebut memiliki karakteristik morfologi berbeda dan dapat bersifat patogen maupun bermanfaat. Fungi are eukaryotic microorganisms that can be seed-borne in rice and act as pathogens, reducing seed quality, germination rate, and yield. Fungal spores or hyphae can remain dormant within seeds. Morphological identification—such as colony color, hyphae, and conidia—is crucial for early detection. This study aims to identify the morphology of seed-borne fungi in rice from North Kalimantan as a basis for early disease control during the seed phase. The research was conducted in four rice-producing subdistricts of North Kalimantan: Tanjung Selor, Tanjung Palas, Tanjung Palas Tengah, and Tanjung Palas Utara in 2020, using a snowball sampling method covering 75% of farmers. From each respondent, 200 grams of rice seed were collected. Fungal detection was carried out using the blotter test and incubated for one week. Identification was done using a stereo microscope (400x and 1000x magnification) based on hyphae and conidia characteristics. Bulungan Regency in North Kalimantan is a major rice-producing area with 14 seed varieties used by farmers. From seed samples across the four subdistricts, four fungal genera were found: Alternaria, Aspergillus, Mucor, and Rhizopus. These fungi have distinct morphological characteristics and may be either pathogenic or beneficial.
