Abstract

Ministry of Environment and Forestry launched a flood prevention program in Garut regency with 3 rehabilitation programs namely conventional tree planting (Conventional Crops), Air Nurseries, and agroforestry forests. Choice of type is the key to success of agroforestry. The most widely planted species in the Cimanuk watershed are cultivars combined with vegetable crops. This study aims to analyze the soil chemical fertility status on eucalyptus-based vegetable agroforestry patterns in some age classes and to analyze changes in soil fertility status after harvest. The soil fertility status is chemically classified in all plots either monoculture or under eucalyptus age 2, 4, and 6 years.. Agroforestry planting patterns can improve the soil fertility status chemically into high categories. Prior to cultivation the mean value of CEC was 24.72 me / 100gr (moderate), Saturation Base 64.19% (high), P2O5 35.57 me / 100gr (very high), K2O 213.48 me / 100gr (very high), and C-org 3.54 % (high). After harvest the average value of CEC is 25.36 me/100g (high), Saturation Base 66.04 % (high), P2O5 77.05 me/100g (very high), K2O 652.83 me/100g (very high), and C-org 3.84 % (high).Key words: agroforestry, Cimanuk watershed, vegetable

Abstract

Peat fire prevention activities conducted by farmers as a form of they role in realizing sustainable agriculture. Sustainable agriculture can be run as to maximizing internal factors such as age, formal education, income, land area, land status, distance of land location and exsternal factors such as interaction with instructor or instructor instructors, community leaders, involvement in farmer groups, information media, and government roles. Using SPSS 25 with validity in order test to test the level of relationship and validity, validity by looking at r count > r table which called then valid and if r count < r table then called invalid and reliability tests to know reliable, if the reliability coefficient is Alpha Cronbach is more than 0.70 (ri> 0.70) and should not be more than 0.90 (ri <0.9). Result of research shown that The Internal and external factors still have a relatively low level connection, because the facilities and infrastructures are not maximized to support sustainable agricultural development. Meanwhile internal factors that have a real relationship are age and formal education while external factors that have a real relationship are involvement in farmer groups, information media, and communication and the role of government. Key words: exsternal factors, internal factors, peat fire prevention, sustainable agriculture

Abstract

Samama (Anthocephalus marcophyllus Roxb.Havil) is a tree with a canopy like a large umbrella so that if planted at any distance it will not affect the shape of the stem (Halawane et al. 2011). This type can flourish in tropical forests with an altitude of 50-1000 mdpl. This is including native Indonesian plants that have the potential to be developed in the development of plantation forests and for other purposes, such as reclamation of ex-mining land, reforestation and shade trees (Mansur and Tuheteru 2010). This is because samama can grow on various types of soil, do not have serious pests and diseases (Pratiwi 2003). In accordance with the permit for the implementation of silvopatura activities in production forest areas which are explained in full in the regulations of the Ministery of Environment and Forestry of the Republic of Indonesia No. P.14/Menlhk-11/2015 concerning procedures for granting business licenses for the utilization of silvopastura areas in production forests with the aim of ensuring sustainable forest management by applying the principles of good governance. In the framework of sustainable production forest management to support food sovereignty programs. Provision of sufficient light space, fertilize and selection of tolerant grass species under stands are the key to the success of silvopastura. Based on the results of the study, it was found that the density of trees with 2 tree/plot with light intensity in the morning was 70.48% and 95.29% during the day. Addition of nitrogen to grass is not needed if the soil used has good fertility. Pennisetum purpureum Cv. Mott has the best tolerance under the same stand as a source of cut grass (intensive retention) and Stenotaphrum secundatum a coarse, hardly perennial grass in the management of silvopastura extensive. Key words: silvopasture, density of tree, shade, samama

Abstract

Gold mining is a human activity with high environmental risk through its tailing, due to the heavy metals content. Lead (Pb) is one of dangerous heavy metals in the world, because its toxicity to organism and environment. Phytoremediation is a method to remove hazard pollutant from environment by using plant. Acacia mangium is fast growing and pioneer tree species which mostly grow on the secondary forest as well as marginal land. Usually, this species is used for revegetation on postmining land. Study on Pb effect to A. mangium is an important issue to support phytoremediation advancement as well as for forest restoration. This study aimed to analyze the effect of Pb with several levels toward the growth and adptability of A. mangium on the gold tailing. The results showed that Pb increment on tailing were significantly effect on the growth and adaptability of the plants. A. mangium showed a well performance even on 900 mg Pb/kg tailing with high tolerance index (TI > 100%). Moreover, this species had ability to accumulate Pb in the root higher than shoot tissue. A. mangium had a good potency as phitoremediant plant, also as revegetation plant on the marginal land, such as on the gold mining tailing. Key words: Acacia mangium, heavy metal, lead, phytoremediation, Pb
