Abstract

Forest fires cause the death of flora, soil damage and smoke disasters. The research was corected at the productivity forest and soil samples were taken through purposive sampling. The result of research show that forest fires cause the death of flora by 100% and erosion occurring at the dept of 5-10 cm. Forest fires cause a significant increase in pH, Ca and Mg mineral soils, and reduce organic C, total microorganisms, total fungi and soil respiration significantly. Forest fires increase soil pH and soil fertility due to ash remaining combustion. The residual combustion ash comes from organic material (natural forest biomass and organic matter) which is burned was which of nutrient needed fan the growth of the vegetation in the forest.Keywords: forest fires, mineral soils, soil fertility, soil properties

Abstract

Forest and land fires become serious problems in Indonesia that could not be well managed until today. This is then the reasons why there is so many activties being conducted in order to find the best solution including fire suppression method. Until today the suppresion methods mostly using water rather than other sources, which actually is not so effective and efficient. The research is proposed to make sure that Gel Pack Extinguishing Agent (GPEA) could be used for fire suppression. Three different fuels used were Pinus merkusii, Shorea leprosula, and Dicranopteris linearis at different of 55g, 65g, 75g, dan 85g. The results of research shown that GPEA with 5 small box per litter of water was the best dosage. The fastes suppression time based on the three fuels was Dicranopteris linearis, and the lowest was Pinus merkusii.Keywords: fuels, forest and land fires, Gel, suppresion methode, dosage

Abstract

Limestone mining activities are damaging soil and enviroment. Revegetation becomes an obligation on every mining sites. Paraserianthes falcataria is one of many species that suitable to be planted in revegetation site. Adding compost and NPK fertilizer can improve soil’s condition. This research objective is to analyze the effect of compost and NPK fertilizer on Paraserianthes falcataria seedlings growth and the exact appropriate dosage for limestone mining’s soil condition improvement. The design used in this research is completely randomized design with two factors. The result shows that addtion of compost on tailing media doesn’t give major effect or statistically not significant on seedling growth of height, diameter, the amount of root nodules, and shoot-root ratio, but statistically significant on wet and dry weight of the seedlings. NPK fertilizer addition on tailing media is statistically significant on the seedling growth of diameter, wet weight, and shoot-root ratio, but not significant different on height, dry weight, and the amount of root nodules. Interaction between compost and NPK fertilizer on media gives effect only at 95% of confidence level. K1N5 sample (with 100 gram composts and 5 gram of NPK fertilizer) gives the best respond on seedling’s growth. Very high levels of Ca in the soil medium will be toxic to the Paraserianthes Falcataria plant.Keywords: Compost, limestone mining, NPK fertilizer, Paraserianthes falcataria

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
