Abstract

Household organic waste can be used as material for organic fertilizer for supporting urban farming activities. Organic fertilizer is beneficial as an effort to reduce waste’s negative impact to environment, and to minimize the use of chemical fertilizers. This research aimed to study the macro nutrient content of fruit peel based-liquid organic fertilizer (LOF) and its effect on the growth of Pakcoy (Brassica chinensis L.). Several fruit peels from household organic waste such as banana, mango, orange, dragon fruit, and papaya peels were used as material for LOF preparation. The research was conducted with completely randomized design (CRD) method with 5 treatments and 5 replications, namely the K- (without fertilizer, only water), K+ (0.2 mL commercial LOF), P1 (0.1 mL fruit peel based-LOF), P2 (0.2 mL fruit peel based-LOF) and P3 (0.4 mL fruit peel based- LOF) for 56 days of observation. The obtained data were analyzed using one-way ANOVA. Results showed that macro nutrients of fruit peel based LOF did not yet meet the quality standards set by the Ministry of Agriculture, and the dose of 0,4 ml fruit peels based-LOF showed the best effect to support the growth of the Pakcoy plant in all Pakcoy growth parameters. Keywords: Fruit Peels, eco enzyme, macro-nutrients, pakcoy

Abstract

Forests are one of the living environments that are directly related to humans. The biggest problem in the forestry sector is the rate of deforestation and degradation. Management of forest resources with the community is a system of resource management that is carried out. Social forestry is a system of managing forest resources in state forest areas or private forests, which provides opportunities for local communities as main actors and partners to improve their welfare and realize forest sustainability. The results of the research reveal that forest management with the community is an example of social forestry implementation. The aim of forest management with the community is to encourage the management of forest resources through a combination of economic, ecological and social aspects in a proportional and professional manner. Keywords: Forest management, environment, social forestry

Abstract

Coffee (Coffea spp.) consumption increased faster than five years ago. However, coffee production availability declined due to the limited field, soil nutrient deficiency, and chemical fertilizer. The aimed research was to obtain a bacteria-producing IAA hormone isolate and to evaluate its density and diversity in improving soil quality and fertility for coffee growth. The rhizosphere soil samples were collected around the coffee plantation in UBF at Sumberwangi, Malang. The sample was isolated using serial dilution on 0.85% NaCl and spread on a Tryptic soy agar medium. The result revealed that the total number of bacteria-producing IAA was 36 isolates, and two isolates (TAS1.2 and TAS 2.6) had higher IAA hormone production at 60 ppm. The selected bacteria can be optimized for a candidate of bacteria-based fertilizer coffee production. Keywords: IAA, density, diversity index, PGPR
