Abstract. Marjenah, Kiswanto, Purwanti S, Sofyan FPM. 2016. The effect of biochar, cocopeat and saw dust compost on the growth of two dipterocarps seedlings. Nusantara Bioscience 8: 39-44. Good growing media contains enough nutrients, light textured, and have the capacity to hold water to create conditions that can support plant growth. The growing media used for propagation has several requirements, that is firm and dense to enhance the growth of stems, has the capability to hold water, guarantee the plant life, and moderate humidity. This study attempts to evaluate the effect of biochar, cocopeat, and saw dust compost on the growth of Dryobalanops aromatica and Shorea balangeran seedlings. An experiment was conducted by using completely randomized block design (CRBD) in factorial with two factors, namely growing media (top soil 100%; top soil 80% + saw dust compost 20%; top soil 80% + biochar 20%, top soil 80% + 20% coco peat ) and two species of dipterocarps seedlings (D. aromatica and S. balangeran). The experiment was carried out in a Forestry Faculty nursery during 3 months. To determine the best growth media, the vegetative parameters of seedlings were measured and the data were statistically analyzed. Survival rates of both of seedlings showed good specification in all types of growing media. The survival rates of D. aromatica for 100% top soil (control); 80% top soil+ 20% sawdust compost; 80% topsoil + 20% biochar; 80% top soil + 20% cocopeat are 100%; 100%; 97.78% and 97.78%; respectively. S. balangeran are 93.33%; 100%; 100%; 97.78%. Quality Index of D. aromatica 100% top soil (control); 80% top soil+ 20% sawdust compost; 80% topsoil + 20% biochar; 80% top soil + 20% cocopeat that are 0.15; 0.14; 0.10; and 0.10; and for S. balangeran 0.09; 0.38; 0.05 and 0.07 respectively.

Biochar enriched with organic fertilizer improves the survival and growth rate of Anthocepalus cadamba seedlings planted on degraded spodosols

“…However, all treatments gave high survival rate, more than 90%, including that of 100% biochar treatment. Biochar application on growth media in nursery also gave high survival for Dipterocarps seedlings (Marjenah et al 2016;Syahrinudin et al 2018). These demonstrate that the use of biochar as main media for raising seedlings in nursery is of interest for the replacement of the conventional media as the availability of these conventional media (topsoils) becoming scarce lately and the use of these conventional media subject to ecological degradation of its originremoving fertile topsoil from the system may lead to nutrient cycle disruption and nutrient shortage of the system.…”

“…Nutrient enriched biochar promoted higher survival rate at all rates of biochar treatment (Table 2). These results suggest that the application of biochar soil amendment coupled with other materials such as fertilizer, sludge and composted organic wastes would further enhance the favorable conditions of plant growth media (Alburquerque et al 2013;Schimmelpfennig et al 2014;Marjenah et al 2016). The addition of these materials into biochar application may further improve nutrient availability, i.e.…”

Biochar Application on Spodosols Soils Promotes Higher Plant Growth and Survival Rate

“…However, all treatments gave a high survival rate, more than 90%, including 100% biochar treatment. Biochar application on growth media in the nursery also showed high survival for Dipterocarps seedling [13,58]. This demonstrated that biochar's use as the primary media for raising seedlings in the nursery is of interest.…”

Komparasi Agribisnis Jamur Tiram (Pleurotus ostreatus) Media Tanam Limbah Sabut Kelapa dan Serbuk Gergaji

“…Begitu juga pada usahatani jamur tiram ada beberapa kendala yang dialami oleh para petani jamur tiram. Kendala yang dialami para petani jamur yaitu kendala dalam bahan baku media tanam, kendala pada tingkat keberhasilan pembuatan baglog atau media tanam, kendala pada proses sterilisasi, lambatnya perkembangan miselium dan lain-lain (Sunandar et al, 2018) (Fatmawati, 2017;Hasriani et al, 2013a;Prasetyawan, 2009;Rambey et al, 2018) Penelitian media limbah serbuk sabut kelapa dan limbah serbuk gergaji secara teknis cukup banyak dilakukan seperti untuk pertumbuhan padi (Antoro & Nelvia, 2018;Yulia et al, 2018), bibit kakao (Hasriani et al, 2013b;Saputra et al, 2019), kelapa sawit (Andri et al, 2017, pembibitan meranti (Marjenah, 2016), kentang (Putra et al, 2019), hidroponik (Hasriani et al, 2013a;James et al, 2010), tanaman hias chrysanthemum (Singh et al, 2015), bahkan sebagai peredam dan bahan konstruksi bangunan di lahan basah (Danley-Thomson et al, 2016).…”
