Pleurotus cytidiosus has the advantage of long endurance, body texture and moisture content slightly thick. Peurotus ostreatus Grey oyster variety has the advantage of long endurance, wide body shape and also a little water content. To obtain superior variety of both species of fungus, it is necessary to cross using the monocaryon fusion mycelium. The purpose of this study to determine whether the mycelium monokaryon fusion methods can be used to cross P. cytidiosus with P. ostreatus Grey oyster variety. The results showed that the mycelium monokaryon fusion method can be used to cross P. cytidiosus with P. ostreatus Grey oyster variety marked with contact zones mycelium makroscopically, while microscopically there is a connection structure of the wedge. The characteristics of mycelium of the cross appear to be attached or united, uneven and smoother. Growth of mycelium dikaryon, faster than monokaryon mycelium.Keywords: Monokaryon Mycelium Fusion, Pleurotus. cytidiosusy, Pleurotus ostreatus Grey oyster Variety ABSTRAK Jamur tiram coklat (Pleurotus. cytidiosus) memiliki keunggulan daya tahan lama, tekstur tubuh yang tebal, dan kadar air sedikit. Jamur tiram putih (Pleurotus ostreatus varietas Grey oyster) memiliki keunggulan daya tahan lama, bentuk tubuh lebar, dan kadar air sedikit. Untuk mendapatkan varietas unggul dari kedua spesies jamur, maka perlu dilakukan persilangan menggunakan metode fusi miselium monokarion. Tujuan penelitian ini untuk mengetahui apakah metode fusi miselium monokarion dapat digunakan untuk persilangan P. cytidiosus dengan P. ostreatus varietas Grey oyster. Tahap awal dalam penelitian ini yaitu pembibitan, kemudian dilanjutkan persilangan menggunakan metode fusi miselium monokarion hingga terbentuk zona kontak kedua miselium dan struktur sambungan apit. Hasil penelitian menunjukkan bahwa metode fusi miselium monokarion dapat digunakan untuk persilangan P. cytidiosus dengan P. ostreatus varietas Grey oyster yang ditandai dengan zona kontak miselium secara makroskopik, sedangkan secara mikroskopik terdapat struktur sambungan 11
Red palm is ornament plant which potentially to be cultured. The scarcity of red palm made it has high market value and need to be preserved. However, the germination growth of red palm is slower than other kinds of palm, so the best way to germinate the red palm seed is needed. The aim of this research is to determine the effect of apliccation some young coconut water concentration and kascing fertilizer to red palm seed germination. The research used factorial completely randomized design with 5 replication, the first factor is young coconut water concentration (0%, 25%, 50%, 75%, and 100%) and the second factor is germination media (steril sand and kascing fertilizer). Variables measured were live germination percentage, speed germination rate, radicula length, and plumula height. Results of this study showed that the best germination media is steril sand and 0% concentration of young coconut water.
Limbah peternakan, seperti kotoran hewan, jika tidak dimanfaatkan dengan bijaksana dapat menimbulkan dampak negatif bagi lingkungan berupa pencemaran udara, air dan tanah, menjadi sumber penyakit, dapat memicu peningkatan gas metan dan juga gangguan pada estetika dan kenyamanan lingkungan. Oleh karena itu, diperlukan upaya untuk memanfaatkan limbah peternakan menjadi produk yang berguna, di antaranya menjadikannya sebagai pupuk organik. Penelitian ini bertujuan untuk mengetahui apakah pupuk organik berbahan dasar kotoran hewan memiliki karakter sesuai dengan pupuk organik SNI (Standart Nasional Indonesia-2011). Penelitian ini menggunakan rancangan penelitian deskriptif. Data penelitian diperoleh melalui analisis laboratorium beberapa sampel pupuk organik berbahan dasar kotoran hewan dan membandingkan hasilnya dengan standart pupuk organik SNI-2011. Berdasarkan hasil penelitian menunjukkan bahwa pupuk organik yang dihasilkan pada penelitian ini telah sesuai dengan SNI-2011, kecuali pada kadar air dan unsur hara makro (N, P, dan K). Kadar air masih harus diturunkan agar sesuai dengan SNI-2011. Selain itu, masih perlu upaya untuk meningkatkan kandungan unsur hara makro pada pupuk organik berbahan dasar kotoran hewan agar sesuai dengan SNI-2011.
The food production process uses a lot of synthetic dyes. Processing of salted quail eggs using natural dyes is still limited. Secang wood (Caesalpinia sappan L.) is a natural coloring agent and its use is still limited. This study aimed to explain the effect of adding secang wood to the sensory characteristics of salted quail eggs. This study used a 3 x 3 factorial completely randomized design (CRD) with 3 replications. Factor A was the level of addition of secang wood powder: 10%, 20% and 30%, respectively. Factor B curing time was 3 days, 6 days and 9 days. The parameters measured were sensory characteristics: color, scent of egg, taste and texture of salted quail eggs. The results showed that the level of addition of secang wood powder and different curing time had no significant effect (P>0.05) on color. Thus, the level of addition of secang wood did not show a significant effect on the scent of egg, taste and texture of salted quail eggs. However, the duration of curing showed a significant effect (P<0.05) on the scent of egg, taste and texture of the resulting salted quail eggs. The addition of 20% secang wood powder and curing 6 days improved the sensory characteristics of salted quail eggs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
