Abstract

Marrango tree (Azadirachta excelsa Jack.) has been introduced as a shade tree for coffee plantations that also produces valuable timber for construction and energy. This paper analyzed the financial aspect of an agroforestry system of marrango tree and coffee plantations, including observations of land management, costs and revenues, financial feasibility and sensitivity analysis. The study was conducted in Rejang Lebong Regency, Bengkulu Province through field observations and interviews. Data was collected through direct observations, household surveys and in-depth interviews of several key actors to deepen the information and verify the collected data. Descriptive quantitative and financial analyses were employed to analyze the data. The results showed that the land management of marrango tree and coffee plant agroforestry in Rejang Lebong Regency was conducted in the traditional way. However, the agroforestry system of coffee plants and marrango tree was financially feasible at the level of 8% discounted rate (NPV = 76,250,582 IDR; BCR = 2.28 and IRR = 22%). This agroforestry system also has good resistance to changes in coffee price, coffee production and marrango tree price. The agroforestry system remained feasible although if coffee production declined by 50%, coffee price decreased up to 40%, and timber production declined up to 50%.  The changes in coffee production and price were the most influential factors on the feasibility of the agroforestry system. This agroforestry system is beneficial for the farmers. Hence, the local government should encourage the community to apply this system.

Abstract

Seed deterioration is the process of deteriorated seed in view of viability that has changed its physiological and nutritional  content.  This paper studies the effect of seed drying and seed storage to the viability and biochemical content of jelutung (Dyera polyphylla (Miq.) Steenis) seeds. Completely Randomized Design was used for different level of seed drying time, i.e.  0, 24, 48, 72, 96 and 120 hours, and Completely Randomized Factorial Design was used for the combination of  seed drying treatments of 0, 24, 48, 72, 96 and 120 hours in different rooms for seed storage (ambient room, air conditioned room, refrigerator) with variables of moisture content, germination percentage and nutritional content. Result shows that seed drying and seed storage treatments pursue  the change of seed viability and nutritional  content of jelutung seed. The period of time in seed drying and seed storage siginificantly influence the moisture content, germination percentage and nutritional composition (lipid, carbohydrate, protein). The longer time of seed drying will effect significantly to the moisture content and germination percentage, increasing the lipid and protein and decreasing carbohydrate. Jelutung seed that was stored in air conditioned room had  better viability compared to  ambient room and refrigerator.

Abstract

The welfare level of farmer in rural Sumbawa was steadily low although the potency of natural resources at their vicinity was high. This paper determines the consumption behaviour  as well as the welfare level a farmer households in rural Sumbawa, Indonesia. The household size, years of education, and farming incomes were used as indicators of on-farm performance. This research was carried out in February until April 2015 at two separate forest areas which were administratively under Labuhan Badas village, i.e.  community forestry (HKm) in the state production forest and private owned forests (POF). A number of 34 respondents perlocation were purposively selected. The multiple linear regression was implemented to analyze factors affecting farmer household consumption behaviour, while the exchange value for income earned by farmer (EVIF) was incorporated to measure the welfare level. The regression revealed that the consumption behaviour  at two groups of respondents were positively related with three indicators, i.e. household size, years of education, and farming incomes.  Meanwhile, the household size affected the consumption behaviour  of the HKm farmers but not the POF farmers.  Furthermore, the consumption is strongly affected by the income generated from both forest areas. The EVIF approach revealed that the welfare of whole farmers were still low (EVIF = 0.74-0.99). The government, therefore, should subsidize rain fed paddy and tobacco seeds varieties which are suitable with the local climate, while the farmers are trained to process the flesh of cashew fruit into wine or chips and encouraged to cultivate calliandra trees for apiculture development and wood pellet or charcoal production.

Abstract

To date, performance of  the management of  Indonesian production forests are discouraging. The concession areas, timber production and employment have been decreasing over time. concern on these matter and to improve management, a research was conducted for six years (2008-2013) and resulted in recommendations to implement the Multi-System of Silviculture (MSS) systems. Two products were generated in MSS; criteria and indicator to guide the selection of  appropriate silvicultural system and supersilvik, a model to develop the best business plans. This paper evaluates  and strengthens the recommendations through the simulation of  MSS products in PT. Sarmiento Parakantja Timber (Sarpatim), Central Kalimantan, Indonesia. Various data variables were used, such as thematic maps of  forest areas, data of  stand, materials, equipments, labors, finances and incomes. Data were processed in a variety of  formulations which were connected to each other in model systems to produce a variety of  outcomes, such as production, finance, employment and tax contributions. Results offer four options to improve PT. Sarpatim performance, one of  which is the best choice. Compared to the former business model under limited silvicultural systems, MSS  projected an increase in the use of  land, timber production and employment by 151-753%. Implementing MSS will provide a better and healthier finance for company with an increase of  NPV up to 193%; as well as for government tax revenues with an increase up to 308%. This MSS case study strongly suggests using the new theory that the management of  production forests is a land and plant-based enterprises, which should put the land as the major capital and silvicultural aspects as the driving engine for production. The policy makers should be able to use these results as a reference in implementing MSS widely as part of  Sustainable Forest Management (SFM) practices.

Abstract

The success of managing the natural environment by involving the community is strongly influenced by the local social conditions. This paper analyzes social capital inherent in the Muara Baimbai Community in Sei Nagalawan Village to manage the mangrove forest as an area valued for tourism. The study was conducted in Muara Baimbai Mangrove Area, Sei Nagalawan Village, Perbaungan District, Serdang Bedagai Regency on June until December 2014. Data were collected by observation, interview using a structured questionnaire, and in-depth interviews. The Muara Baimbai Community has strong social capital in managing the mangrove ecotourism area. An indicator of a strong social capital is a community institution which is run properly. The success of the community to rehabilitate the mangrove area in Sei Nagalawan and to utilise its resources in a sustainable manner is the result of high levels of participation of the members and the role of active cadres as symbolic power that encourage, drive, and motivate the community in their struggle. Strong motivation, fair work allocation and benefits among the members, strong internal connection, and wide external network are very important to strengthen social capital. Furthermore, the increasing welfare gained by the coastal community through increasing economic income, job opportunities, and knowledge are the benefits derived from the sustainable forest management that can maintain the existence of the community and their natural resource

Abstract

Nutritional deficiency is still a problem faced by many families in Indonesia. One of the important issues is the level of protein consumption that is still below the minimum required standard. Edible insects could be one alternative of protein sources  since their availability in the nature is quite abundant. This paper analyses six edible species of both cultivated and wild insects for its proximate compositions to measure their nutritional value. The cultivated insects consist of cricket (Gryllus sp.), giant mealworm (Zophobas morio F.), yellow mealworm (Tenebrio molitor L.), and silkworm (Bombyx mori L.), and the wild insects consist of javanese grasshopper (Valanga nigricornis Burm.) and paddy locust (Nomadacris succincta L.). Results shows that the nutritional composition of insects varies widely. Each 100g of dry weight contains of 32.59-76.69% of protein, 6.9-29.47% of fat, 0.92-30.76% of carbohydrate, 2.80-5.79% of ash, 407.34- 517.50 kcal of energy, and minerals about 24.82-31.22 mg of calcium (Ca) and 3.15-4.1 mg of iron (Fe). Some species such as grasshoppers, silkworm pupae and crickets have high protein content which potentially can be utilized as an alternate protein sources to fight against malnutrition and to increase nutritious food consumption. Efforts should be made to encourage the consumption of edible insects as an alternative source of protein. It is especially important to those who live in and around the forest, since the forest area is an excellent habitat for various species of insects.
