Abstract

To control quality of rainfed areas as well as improvement of farmers’ welfare is efforts already has been done by local government (Ponogoro) however it’sstill not success yet because it used to partial approach. Therefore, it is very important to research and develop model how to control quality of rainfed based on community empowerment with integrated (system) ap­proach.The location of research is in Ponorogo Districtwith 326 respondens, consist of 6experts, 20 linkage agencies staff and 300 farmers. Beside useAnalytical Hierarchy Process (AHP), Interpretative Structural Modelling (ISM), and System, this re­search also use univariat and bevariate analyze (Chi- Square and Structure Equation Model- SEM).Based on data and informa­tion that collected and analyzed, this research develop model that reflected the the real situation (fact), that can be simulated and validated. The model is established with system approach of population, local government services and ecology. The model vali­dated by absolute mean error (AME) and absolute variation error (AVE) that reflected variance between actual and value from model less than 10%, it show the model is a valid.This mean model able to simulate any changing of rainfed areas quality con­trol both in short or long term period.Other significant factors that related with rainfed areas quality control is farmers know­ledge (p-value= 0,030) and farmers behavior (p-value=0,040).The empowerment of farmers indicated by food and nutrition security (γ = 1), settlement and sanitation security (γ = 0.23), healthy security (γ = 0.01)and education security (γ = 0.24). The empowerment of farmers influenced by coping strategy (β=0.41), that reflected by how farmer survive in production, consump­tion and marketing of agriculture with respective of γ is0.59, 0.27, 037 and 0.42. In line with these statistic analysis AHP, ISM results and validation model, this research formulated empowerment policy focus on life skill development through farmer group. In the beginning process of life skill development focus on soft skill and then hard skill later on up to achieve sustainable self help group in managing their rainfed areas.Keywords: rainfed, quality, control, empowerment, model, system, coping strategy

Abstract

Community forest that privately owned at Kuningan Regency, West Java Province, have showed forest cover improvement at average of 5.86% during 2003 –2009. The main factor which contributes to this improvement was economic motivation of owners as a response to growing market of timber originated from community forest.  This forest potentially serves as protected area outside state forest in land use plan of Kuningan district. Due to its characteristic as common-pool resources in the context of its protection function, privately owned community forest requires certain institutional arrangement to enable sustainable forest management resulting sustainable benefit for public. The aim of this study is to assess policy framework and its implementation designed to promote sustainable community forest development. The framework for implementation analysis was applied in this research with emphasis on the policy variable. The result showed that existing policy framework is weak to support sustainable management of community forest. They were characterized by unclear formulation of concepts in policy documents, inappropriate causal theory, unbalance financial resource allocation, very much detail and almost rigid in technical guidelines thereby hindering the achievement of policy objectives. Keywords: community forest, sustainable forest management, policy variable, policy analysis

Abstract

Kapoposang Island and the surrounding waters has been appointed by Indonesian Governmet to be a part of waters tour park in South Sulawesi, implying the requirement of the marine resources, including seagrass ecosystems in this area, should be well managed in order to provide biodiversity protection and sustainable use of the seagrass ecosystems. For this purpose, one of basic required information is seagrass distribution and habitat structure. This study was aimed to 1) observe the location of continues seagrass beds, 2) identify the habitat structure in each site of continues seagrass beds. A combination of visual observation and transect method was applied to determine the sites of continues seagrass beds, while seagrass habitat structure was identified based on ecological habitat structure model. Study results revealed that continues seagrass beds were only found in five different sites of Kapoposang coastal waters. Seagrass habitat structure among the five sites were in variable and the highest seagrass cover was found in two sites, namely 1) site A in the north-west part of the island (S04o41'42.5"; E118o56'59.5") dominated by Thalassia hemprichii and 2) site E located in the north part of the island (S04o41'57.8"; E118o57'45.7") dominated by Enhalus acoroides. Both of these sites were different in heterogeneity but similar in complexity. Keywords: Thalassia hemprichii, Enhalus acoroides, continues seagrass beds, habitat structure

Abstract

As a company engaged in the industrial sector by producing certain components and localized in an industrial area, there will be an impact on the environment. These impacts can be positive in the form of employment, reducing dependence on imported heavy equipment, increase in foreign exchange due to reduced imports and increased exports, increased government revenue from taxes, public facilities improvement and supporting infrastructure, and opening up opportunities for other related industries. These impacts can also be negative in the form of environmental degradation such as noise disturbance, dust, and micro climate change, and changes in social and cultural conditions surrounding the industry. Data analysis was performed descriptively and with the Structural Equation Model (SEM). SEM is a multivariate statistical technique which is a combination of factor analysis and regression analysis (correlation), which aims to test the connections between existing variables in a model, whether it is between the indicator with the construct, or the connections between constructs. SEM model consists of two parts, which is the latent variable model and the observed variable model. In contrast to ordinary regression linking the causality between the observed variables, it is also possible in SEM to identify the causality between latent variables. The results of SEM analysis showed that the developed model has a fairly high level of validity that is shown by the minimum fit chi-square value of 93.15 (P = 0.00029). Based on said model, it shows that the company's performance in waste management is largely determined by employee integrity and objectivity of the new employees followed later by the independence of the employees in waste management. The most important factor that determines the employee integrity in waste management in the model is honesty, individual wisdom, and a sense of responsibility. The most important factor in the employee objectivity in waste management is the support of accurate data in each report of waste management by the company and transparency on reports of the company’s activity. While the factors that determine the employee independency is the company's interests, a sense of employee volunteering, and openness between the company and employees. Keywords : heavy equipment industry, management, environment, Structural Equation Model (SEM)

Abstract

Erosion constitute one of constraint for dryland farming in Indonesia. In dryland farming in transmigration sites, almost all factors led to the high rate of erosion: high intensity of rainfall in a short period, steep slope, opening of forest landcover for cultivation, and the absence of conservation efforts. This research was conducted to determine the soil conservation measures according to spatially calculated erosion. The calculation of the erosion rate was first carried out spatially, so that appropriate conservation could be recomended. The study was conducted in Rantau Pandan SP-3, Jambi Province. The amount of erosion was calculated using the method of Universal Soil Loss Equation (USLE) (Wischmeier & Smith, 1978). The results of the research showed that the magnitude of the maximum erosion in transmigration site of Rantau Pandan SP-3 ranged from 0.004 tonnes/ha/year to 496.97 tonnes/ha/year. The magnitude of this erosion is the maximum erosion in some land use types in the settlement and other part of land. Lands in Rantau Pandan SP-3 have an erosion hazard rate which were classified as mild to very severe. Tolerable erosion at Rantau Pandan SP-3 ranged from 29.7 to 35.8 tonnes/ha/year, taking into consideration the 300 years lifetime of soil. Spatially, erosion calculation can be done using several assumptions in accordance with the observations of field conditions. In each land use polygon can be assigned a maximum amount of erosion, which can then be used for the determination of soil conservation techniques. As erosion considered is the maximum erosion, protection against erosion can be guaranteed. Key words: Dryland farming, erosion hazard, landuse planning, spatial

Abstract

One of the potency for development of Sangihe Islands is sea and the availability of fish resources which is relatively high, both in terms of quantity and diversity. One of the fish types with high quantity in this area are pelagic fish group. This research aims to analyze the management of small pelagic fishing in order to maintain its sustainability. The research result indicate that the average sustainable production of the small pelagic for 20 years (1988-2007) observation was 3,128.45 tons/year. Depreciation value has reduced the rents value received by fishermen. With the method of the present value, the revenues from the market at discount rate of 15% should be Rp 274.97 billion. However, due to depreciation, the amount received just Rp 118.59 billion only. For the optimal and sustainable fisheries management, the effort level for small pelagic capture should be 5,342 trips/year at discount rate of 15%. To maintain the sustainability, the level should be lowered down around 46% from the present level in small pelagic management. Keywords : Sangihe archipelago, CYP, MAPLE, development of the small pelagic fishes

Abstract

Landuse planning according to biophysical and economical land suitability as well as basic allocation for transmigration should be done in order to improve the well-being of transmigrants. Suitability should be analyzed for the selection of commodities which are the most appropriate biophysically and profitable economically. The study was done in the settlements unit of Rantau Pandan SP-1, Jambi Province. The study was conducted to determine the suitability of each part of land for cultivation of food crops, vegetables and perennial crops and to see the biophysical suitability and economical feasibility. The goal is to recommend the most appropriate type of cultivation. This study integrate the Arc-View GIS and Automated Land Evaluation System (ALES) in the analysis of land suitability. The results showed that four agricultural commodities were observed showing land suitability class domination of S3 (marginally suitable) with the most dominant limiting factors were erosion and nutrient retention. The results of the analysis have been used for the determination of land use recommendations in the transmigration sites, presented spatially. Recommendations given based on the results of the analysis were not always in line with the land use recomended by government on dry land transmigration. Nonetheless, these results was suggested to be applied, either by considerations of conservation land and the consideration of economic benefit and farmers welfare. Key words: Land evaluation, transmigration, dry land farming, geographic information system

Abstract

As a company engaged in the industrial sector by producing certain components and localized in an industrial area, there will be an impact on the environment. These impacts can be positive in the form of employment, reducing dependence on imported heavy equipment, increase in foreign exchange due to reduced imports and increased exports, increased government revenue from taxes, public facilities improvement and supporting infrastructure, and opening up opportunities for other related industries. These impacts can also be negative in the form of environmental degradation such as noise disturbance, dust, and micro climate change, and changes in social and cultural conditions surrounding the industry. This research was conducted to support increasing effectiveness and efficiency of corporate management, by determining alternative forms of managing the heavy industrial equipment components environment (PLIKAB)-based on participation and society partnerships. The determination of alternative uses analytical hierarchy process (AHP) with the help of the Criterium Decision Plus v3.04 software. These results indicate that according of experts, the environmental management of industrial waste heavy equipment components must consider the technological aspects of its management. This can be seen from the weighting of each element that indicates the technology element has the greatest weight, which is 0.456. Besides that, elements of human resources is also quite important (weight 0.289) as the manager and the supporting policies (0.140) as a boost to management regulations. Aspect Capital (0.075) and marketing (0.042) is currently not perceived as barriers. While the most influential actor in the management is the company (0.451), other stakeholders have enough role is the community (0.234). Jababeka (0.211) and cooperative business (0.104) has a smaller role in the management. The purpose element in relative management has a weight that is relatively balanced with elements of revenue (0.336) is the primary consideration in determining management strategies, although it should not ignore the aim of maintaining environmental quality (0.299), the purpose of minimizing conflict (0.194), and the purpose of increasing competitiveness (0.170). The best alternative for the management of industrial waste components of the heavy equipment is to form managers based on partnerships by different stock ownership (0.791). It is considered much better than by forming managers based on partnerships by the same stock (0.209). Key words : heavy equipment industry, management, environment, analitycal hierarchy process (AHP)
