The yellowing disease on pepper plant (Pipper nigrum L) caused by plant-parasitic nematodes and F. oxysporum infection is a major disease in Bangka island. The wound that caused by plant-parasitic nematodes will facilitate infection into roots by the pathogen of F. oxysporum easily. This caused the plant sensitive to drought and nutrient deficiency. Utilization of endophytic microbes is one of biological control that environmental friendly and to support sustainable agriculture. The aim of this study was to explore endophytic isolates can inhibit the growth of F. oxysporum in vitro. The endophytes were isolated from bamboo root and selected their antagonistic potential against F.oxysforum by dual culture methods. The study resulted an endophytic bacteria and 13 isolates of endophytic fungi that inhibit mycelium growth of F. oxysforum. The antagonistic activity of endophytic bacteria to F. oxysforum is 28.25% by antibiosis mechanism and endophytic fungi, about 11.00-58.25% by space colonization and nutrition competition on substrate.

Pleurotus ostreatus merupakan jenis jamur tiram putih yang mempunyai manfaat dari segi kesehatan, lingkungan dan ekonomi. Permintaan pasar tinggi sementara petani jamur tiram putih di Pulau Bangka masih sedikit. Desa Pagarawan, Bangka dengan ikon jamur tiram putih mencoba menjawab tantangan tersebut, namun terkendala dengan keterbatasan keterampilan masyarakat terutama dalam produksi bibit dan baglog jamur. Kegiatan Program Kemitraan Masyarakat (PkM) melalui kegiatan budiaya jamur tiram putih skala rumah tangga dengan konsep budidaya dari mulai pembuatan bibit sampai produksi menawarkan alternatif solusi untuk mewujudkan ikon tersebut di Desa Pagarawan. Metode yang dilakukan dalam kegiatan ini adalah pelatihan pembuatan bibit F0, F1, F2 jamur tiram putih dan baglog. Media F0 menggunakan agar kentang, media F1/F2 menggunakan jagung sementara media baglog terdiri atas serbuk kayu, kapur pertanian, gipsum, dedak, dan dekomposer EM4. Hasil pembuatan bibit F0 dari 500 mL media agar kentang adalah 7 buah bibit, namun semua hasilnya mengalami kontaminasi. Dari media jagung 1,2 kg dihasilkan 8 buah bibit F2 jamur tiram. Baglog yang dihasilkan dari 116 kg serbuk kayu adalah 119 baglog dengan komposting dan 97 baglog tanpa komposting. Keberhasilan pembuatan bibit dan media produksi (baglog) jamur tiram putih ditentukan oleh pemahaman terkait teknik sterilisasi. Peningkatan keterampilan masyarakat terkait teknik budidaya jamur tiram terutama pada pembuatan bibit dan baglog sedikit demi sedikit mengalami kemajuan, yang terbukti dengan adanya inisiatif tinggi dari mitra produksi untuk membuat bibit jamur tiram secara mandiri

AbstrakPagarawan merupakan salah satu desa di Kabupaten Bangka dengan ikon jamur tiram putih, sehingga berpotensi mengembangkan usaha budidaya jamur tiram skala rumah tangga. Disamping itu, desa ini selalu membeli baglog jamur dari luar dan belum berani memproduksi sendiri dikarenakan belum mempunyai pengetahuan dan keterampilan mengenai budidaya jamur tiram skala rumah tangga. Kegiatan ini dilaksanakan di salah satu rumah warga Pagarawan sebagai mitra produksi yang bersedia menyediakan tempat budidaya. Tahap awal yang dilakukan sebelum melakukan budidaya adalah persiapan sarana, prasarana dan kegiatan sosialisasi. Persiapan yang telah dilakukan adalah pembuatan kumbung pembibibitan, kumbung inkubasi, kumbung budidaya, dan kumbung pengomposan. Kegiatan sosialisasi budidaya jamur juga sudah dilaksanakan termasuk sosialisasi penggunaan sarana prasarana kepada masyarakat Pagarawan. Hal tersebut menunjukkan antusiasme dari masyarakat desa sehingga siap melangkah ke tahapan berikutnya, yaitu pelatihan budidaya jamur tiram putih skala rumah tangga agar dapat melaksanakan kegiatan budidaya jamur tiram secara mandiri di PagarawanÂ Kata kunci: Bangka, Jamur Tiram Putih, PagarawanÂ Making Kumbung as a Preparation for Mushroom Cultivation in an Effort to Realize the White Oyster Mushroom Icon in Pagarawan Village, BangkaAbstractPagarawan is one of the villages in Bangka Regency with an white oyster mushroom icon, thus increasing the dvevelopment of the household scale oyster mushroom busines. In besides, this village always buys baglog mushrooms from outside the village and has not succeeded in producing it by themselves because they have not the knowledge and skills about household-scale oyster mushrooms. This activity was carried out in one of the houses of the citizens of Pagarawan as a production partner that provided a cultivation place. The initial stage carried out before conducting cultivation is the preparation of facilities, infrastructure and socialization activities. Preparations that have been made are making kumbung of nursery, incubation, cultivation and composting. Mushroom cultivation socialization activities have also been carries out including the socialization of the use of infrastucture for the poeple of Pagarawan. This Shows the enthusiasm of the village community so that they are ready to go to the next stage, namely training on the cultivation of white oyster mushrooms at a household scale can be carried out oyster mushroom cultivation activities independently in PagarawanÂ Key words: Bangka, white oyster mushroom, Pagarawan

Colletotrichum capsici infection in chilies significantly affected the yields. The use of chemical fungicides to control this pathogen has negative effects on health and the environment. The use of botanical pesticides is one alternative to control C. capsici. This study aims to determine the effect of a type of plant extract with a certain concentration to effectively inhibit the growth of the C. capsici The study used a completely randomized design (CRD) with five levels of treatment and five times replication. The treatments were no treatment/negative control, chemical fungicide (contains 70% propineb)/positive control, papaya leaf extract (20%), betel leaf extract (25%), and galangal rhizome extract (30%). Each experimental unit was repeated three times, each repetition using duplo petridishes. The results showed that the treatment had a significant effect on the inhibition of C. capsici in the PDA medium. Botanical fungicide treatment with galangal rhizome extract (30%) was able to significantly inhibit the growth of C. capsici compared to betel and papaya leaf extracts, although it was not as effective as chemical fungicides (contains propinep 70%). The inhibitory abilities of galangal rhizome extract (30%) and chemical fungicide (70% propineb) were 8,34% and 19,91%, respectively.

Deteksi awal penyakit kuning yang disebabkan oleh nematoda parasit Radopholus similis dan Meloidogyne incognita serta cendawan patogen Fusarium oxysporum dan Fusarium solani relatif sulit, tanaman dapat diduga terinfeksi setelah menampakkan gejala menguning pada bagian daun. Perubahan struktur anatomi daun lada yang terinfeksi penyakit kuning sejauh ini belum ada laporan tertulis. Penelitian ini dilakukan untuk membandingkan struktur anatomi daun lada yang tidak terinfeksi dan terinfeksi penyakit kuning. Penelitian ini menggunakan dua metode yaitu whole mount untuk membuat sayatan paradermal dan free-hand technique untuk membuat sayatan transversal. Pengukuran kadar klorofil menggunakan spektrofotometer pada panjang gelombang 649 nm dan 665 nm. Hasil pengamatan menunjukkan bahwa kerapatan stomata dan panjang sel epidermis berbeda nyata antara tanaman lada yang terinfeksi penyakit dengan yang sehat dan tidak berbeda nyata pada karakter indeks stomata, tebal kutikula atas dan bawah, tebal epidermis atas dan bawah, tebal bunga karang, tebal palisade, panjang dan lebar sel stomata, panjang dan lebar sel penjaga, lebar sel epidermis, tebal hipodermis atas dan bawah, tebal daun, luas daun, dan kadar klorofil. Daun tanaman lada terinfeksi memiliki stomata lebih rapat dan panjang sel epidermis lebih pendek dibandingkan dengan daun pada tanaman tidak terinfeksi.
