Abstract

Mangrove forests in Indonesia has been declining and need rehabilitation efforts. The rehabilitation it self needs actual data af the site. Bulaksetra mangrove was destroyed because of tsunami disaster. Based on that condition the purpose of this research was to consider the typology of area and to explore the condition of mangrove vegetation at Bulaksetra, Pangandaran, West Java. Variabel to be measured in this research were stem diameter, tree hight, number of individual, and depth of inundiation. Data colection method was carried on using a combination of between strip method for trees inventory and strip square method for regeneration, totaled 34 unit transects. The depth of inundation performed at 27 sampled points spread at all research areas. Our result obtained showed that, mangrove vegetation at Bulaksetra consists of three classes of crown density: high mangrove density, medium mangrove density, and low mangrove density lead at 3 tipology catagories (A1 : high water inundation <2 cm area; A2: high water inundation 2–5 cm; A3: high water inundation > 5 cm). In this moment Bulaksetra area is covered by 19 mangrove species, in which 8 species are true mangroves. A1 and A3 land tipologyes dominated by Avicennia alba, meanwhile A2 land tipology dominanted by Nypa fruticans.Generally mangrove vegetations in Bulaksetra does not from a zonation but growing mixed in this area.Key words: Bulaksetra, mangrove, typology, water inundation, zonation.

Abstract

Soil as the affiliation of biotic and an abiotic components that support the living of soil microbe. Plants can grow well when it was supported by the available of soil microbes, one of them was arbuscular mycorrhizal fungi (AMF). AMF is a symbiotic mutualism between fungi and plant roots. AMF found almost 80% of plants kingdom, one of them is jabon (Anthocephalus cadamba). The research purposed to identify the diversity of AMF under the jabon plantation (Durenan dry soil, Sudimoroharjo dry soil and Sudimoroharjo wet soil ex rice field). The soil samples was obtained from three different jabon plantation location. The result of this research showed that there were three genus of AMF e.g. Glomus, Acalauspora and Entrophospora, found in jabon plantation planted in Durenan dry soil and Sudimoroharjo wet soil meanwhile jabon planted in Sudimoroharjo wet soil could only be found 2 genus, such as Glomus and Acalauspora.Key word: arbuscular mycorrhizal fungi, diversity, genus, jabon

Abstract

The policy on forest rehabilitation and reclamation have been implemented since 1950, but not effective decrease the extend of the critical forest and land yet. The objective of this research was to formulate option of effectiveness enhancement of forest rehabilitation and reclamation policy implementation. This research applied the theory that developed by Edward III and IDS’s policy process. The policy text (rule in form) of forest rehabilitation and reclamation has not been used effectively to solve the solve the problem on the ground because the lack of sufficient regulation on the pre-condition, maintenance and responsibility in regards to the asset lost, participation, empowerment and transparency. There is divergent in the implementation of forest rehabilitation and reclamation policy. The implementation of policy requires high transaction cost with limited participation and did not legitimate due to ineffective communication, structure of birocracy, disposition/attitude and resources. To increase the effectiveness implementation of policy and institution on forest rehabilitation and reclamation, the goverment have to improve the effectiveness of communication, structure of birocracy, disposition/attitude, and resources. Furthermore, the result of this research also recommends the importance of network development through social movement by using mass-media and social media, which will be usefull to provide pressure on the policy development process by addressing the counter policy narative.Key words: efectiveness, implementation, policy, rehabilitation, reclamation

Abstract

Ecosystem damage as a result of mining activity is very harmful to the environment. One of the strategy repairing the condition of post-mining land is to use legume cover crops, one type of legume cover crops is Desmodium spp., that has ability to form a symbiosis with AMF and rhizobium. The aim of this study was to determine the diversity of AMF from the four types of rhizosphere Desmodium spp. from PT. Cibaliung Sumber Daya, Banten with different types of host plants. The sampling technique of soil and roots were done by non propotional method. Soil samples were trapped with some types of host plants. Spores were isolated by wet-seaving and decanting technique, then the density of spores was measured and identified. The results showed an increasing number of spore and diversity of AMF. The number of spore before trapped was 10-89 spores per 20 g soil then increased to 16-114 spores per 20 g soil. While the AMF diversity before trapped found only 9 type of spores, consists of 8 type Glomus and 1 type Acaulospora. After trapped increased to 26 spores type AMF consists of 23 type of Glomus and 3 type of Acaulospoara. The root colonization was in range of 22.2 - 95.5%.Key word: Desmodium spp. , Cibaliung, Cover crops.

Abstract

A Survey in West Java shows that Mindi (Melia azederach Linn.) is frequently found on the community forest lands as part of a mixed cropping system. These community forest lands have a potential to support food security. Soybean is an important food crop as source of protein in Indonesian. This study aimed to observe the growth of Mindi and soybean in an agroforestry system. This study used a split plot design which consists of two factors. The main factors was Mindi which planted using shade and without shade and the second factors are soybean variety (Argomulyo, Anjasmoro, Grobogan, and Wilis) using four replication. The results showed that differences of Mindi cropping method did not significantly affect the Mindi growth (height and diameter) which has been observed for three months. Wilis had the highest survival rate than others varieties. Both factor shade and varieties giving a very significant effect on the kedelai height at the 3-7 MST age. In addition, it's also very significantly affected the number of leaves trifoleat at the age of 3, 4, and 5 MST. Soybean production in Mindi agroforestry system gaves the higher yield than monoculture system at three months age.Key words: Agroforestry, mindi, soybeans, shade, variety.

Abstract

System which integrating forestry and agriculture is known by agroforestry. Utilizing of unproductive land below the trees will be more optimum. Sentang (Azadirachta excelsa Jack) is one of the plants that can be used in agroforestry system. The aim of this research was to know the effect of agroforestry toward tree dimension and production of some soybean varieties. Research design that was used in this research is split plot design that consisted of 2 factors and three repetitions. Planting pattern as a main plot is a the first factor, consisted of planting pattern of agroforestry (S1) and monoculture (S0). The second factor that was a submain plot is some varieties of soybean which consisted of variety of Grobogan, Anjasmoro, Tanggamus, and Wilis.The results shows that accretion mean of tree height, stem and crown diameter of Sentang in agroforestry plot are bigger than in monocultural plot. Lateral root in monocultural plot is deeper than in agroforestry plot. The difference of plant growth in each planting pattern of agroforestry is affected by interaction among plant component. Utilizing of some soybean varieties in agroforestry of sentang one year old did not result significant production than in monoculture pattern. In this research, variety Tanggamus and Wilis on monoculturural plot has better growth and production than variety of Grobogan and Anjasmoro.Key words: agroforestry, tree dimension, sentang (Azadirachta excelsa Jack), soybean, varieties.
