Abstract

Forests are important habitats that support an ecosystem consisting of various types of plants that have production potential and litter decomposition rates. This research aims to find out how to calculate the production and decomposition rate of litter in homogeneous forest and heterogeneous forest terrestrial ecosystems. The research was carried out in homogeneous and heterogeneous forest areas in the IPB University campus area, Bogor Regency, West Java Province. The sampling process seemed to be carried out using 1x1 m nylon mesh litter trap method for 5 weeks. The results of the research show that the composition of the species that grow in heterogeneous forest areas is Kisabun (Filicium decipien), Sawo kecik (Manilkara kauki), Bisbul (Diospyros blancoy), Water guava (Eugenia aduea), Matoa (Pometia pinnata), Pinus (Cupressus lusitanica), and Meranti (Shorea sp), while in the homogeneous forest ecosystem is the rubber tree (Hevea brasiliensis). The amount of waste collected in heterogeneous forest ecosystems is greater than in homogeneous forest ecosystems (Rubber forests), namely 98 grams and 5.2 grams respectively with results in heterogeneous forest ecosystems of 7.2 grams dry weight from 10 grams wet weight, whereas in homogeneous forest ecosystem (rubber forest 0.8 grams dry weight from 2 grams wet weight). The decomposition rate of litter in heterogeneous ecosystems is 0.21 grams/year, while in rubber forest ecosystems it is 0.17 grams/year.

Abstract

The vegetation profile is a vertical and horizontal description as well as the structure and species composition of a vegetation which includes the dominance of canopy cover, species diversity, species dominance, species frequency, species density and undergrowth. This research aims to obtain an overview of the composition, vertical and horizontal structure of vegetation so as to provide information about tree dynamics and ecological conditions as well as to view tree architectural models. The method for collecting community profile data is carried out in each sample plot measuring 20x20 m with data requirements such as: trunk diameter at DBH height, tree height, tree height, canopy limit, and tree canopy projection. Based on data on tree height and diameter, it was concluded that the trees in the research plot area were trees of the past because they had a total height of between 20-54 meters with a trunk diameter of ±1.63 meters. the results of drawing architectural profiles of tree canopy projections horizontally and vertically so that we can see models of canopy closure and competition for sunlight in homogeneous forest tree communities consisting of the Agathis loranthifolia species. The results of the horizontal and vertical projection of the architectural profile of the tree canopy can be seen so that the model of canopy closure and competition for sunlight in a homogeneous forest tree community consisting of the Agathis loranthifolia species can be seen. The ecological function of the Agathis loranthifolia type is very good in maintaining the environment, related to groundwater storage which can reduce the impact of soil erosion rates. Certain tree architectural models influence the transformation of rainwater into stem flow rate, water through the canopy, infiltration and surface flow rate in an area which is related to the role of vegetation as disaster mitigation.

Abstract

The development of the agricultural sector is the mainstay of economic development. Empowerment of land resources as a basis for agricultural activities should receive more emphasis and attention from the government and other related parties. For this reason, strategic steps are needed to build public opinion and the government that dry land is the hope for the future of agricultural development to increase food security. The study used a descriptive method. The data collection technique used a survey technique. This study was conducted in North Lombok Regency, precisely in Bayan District, which was determine4d by "purposive sampling" with consideration of Bayan District. The results of the study showed that there were 7 types of planting and livestock patterns applied by respondent farmers in the dry land area of ​​Bayan District, North Lombok Regency with a combination of plant types that varied quite a lot between planting patterns, namely corn, rice, peanuts and cassava. Each planting pattern is integrated with livestock. Of the 7 planting patterns, there are 3 dominant planting patterns carried out by farmers, namely, the corn + livestock planting pattern as much as 40%, then the rice + livestock planting pattern (26.25%) and 16.25% for the rice + corn + livestock planting pattern. The cropping and livestock pattern that provides the highest income at the research location is rice + corn + livestock (X6) of 10,995,510.00 per hectare per year and the lowest income is in the peanut + livestock planting pattern (X4) of 2,808,721.60 per hectare per year.
