Abstract

Pola penyebaran anakan jenis pohon emergent (Shorea sp.), kanopi (Maduca malaccensis) dan toleran naungan (Aglaia tomentosa) telah diamati pada hutan dataran rendah luapan banjir di Berau, Kalimantan Timur. Hasil penelitian menunjukkan bahwa, penyebaran anakan ketiga jenis pohon tersebut sangat dipengaruhi oleh agen dispersal buah. Anakan Shorea sp., yang mana memiliki buah tipe samara, sebagian besar tersebar pada bagian Utara-Barat pohon induknya, mengikuti arah angin yang menerbangkan buahnya. Anakan dua jenis lainnya, yang mana buahnya yang bertipe berry sangat disukai oleh binatang mamalia, menyebar secara lebih merata. Struktur populasi anakan ketiga jenis tersebut menunjukkan kecenderungan yang berbeda. Shorea sp. menunjukkan struktur populasi berbentuk huruf J terbalik yang sangat tajam, sedangkan struktur populasi anakan dua jenis lainnya cenderung berbentuk garis horizontal. Perbedaan struktur populasi tersebut terkait dengan toleransi jenis-jenis tersebut terhadap naungan. Buah Shorea sp. yang jumlahnya melimpah segera berkecambah setelah jatuh, namun pertumbuhan anakan selanjutnya tertahan oleh naungan kanopy hutan yang sangat rapat.

Abstract

The allelopathic substances are organic agents which are produced and released by a plant that cause alteration on the neighboring plants. The characteristics of allelochemicals usually inhibit germination of other species and sometime will reduce growth of the other species which associate with the producer of allelochemicals. The mechanism of allelochemicals can be used to suppress a germination of Echinochloa colonum L. and Amaranthus viridis L. These plants are weeds species of rice. The aims of this research were to study the allelochemicals effect from the leaf of pines (Pinus merkusii Jungh. et de Vriese) on germination of Echinochloa colonum L. and Amaranthus viridis L.. The experimental design used Completely Randomized Design with five replicates for each concentration (0, 250, 500, 750, 1000 ppm). The result which was analyzed with One-Way Analyze of Varians (ANOVA) indicated that giving a pine leaf extracts had an inhibitor effect on germination of E. colonum L. and A. viridis L. Keywords: Pinus merkusii Jungh. et de Vriese, allelopathy, weeds, Echinochloa colonum L., Amaranthus viridis L. References

Abstract

Production of cocoon and raw silk in South Sulawesi have decreased in recent years. One of the problem is misleading policy formulation and implementation. The purpose of this studies is to know the policy of sericulture that have implemented in South Sulawesi. The method of analyses are discourse analysis/narrative, actors/network, and politics/interest. The result indicated that three factors ie. narrative, actors and interests among stakeholder in sericulture development disturb the policy implementation so it wouldn’t achieve the goal. Incorrect problem formulation also disrupt the sericulture development so it didn’t increase cocoon and raw silk production in South Sulawesi. Key words: policy, process, sericulture, South Sulawesi

Abstract

Sub watershed of Latoma has to be considered as an area of the important regions in South East Sulawesi, because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which has been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Latoma sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Run-off Curve Number (CN) model based on Geographical Information Systems (GIS). The result of the research revealed that the run-off curve number is 70,34. It showed that maximum potential water retention or infiltration rate is 107,10 mm. Restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability objectives. Keywords : Watershed, land use, run-off curve number (CN), GIS

Abstract

Design of agroforestry has the objectives of improving the system which has been existing and providing directives for agribusiness on the basis of physical, economical, and socio-cultural condition. Design of a system is inevitably related with pre-diagnosis and diagnosis activities which are aimed at discovering the existing constraints and problems inside the system, followed by technological intervention for system improvement and determining the best agroforestry system in critical land condition. Method used in this study was identifying the existing agroforestry system, followed by evaluation of land suitability, financial analysis and community social analysis. This study found three agroforestry systems based on the existing components, namely agrisilviculture, silvopasture, and agrisilvopasture. Evaluation of land suitability showed that in general, land suitability ratings for woody crops and perennial crops were categorized as moderately suitable (S2), while those for annual crops / non rice food crops were categorized as marginally suitable (S3). Results of financial analysis showed that all existing agroforestry system are feasible to be practiced, with highest benefit cost ratio 2.7 was found in agrisilvopasture system. On the basis of landscape consideration, species of Non-MPTs were more adapted if they were planted in hill ridge, while that of species of MPTs and perennial crops in slope and valley, and that of annual crops in valley. Key words: agroforestry, land suitability, critical land, design

Abstract

This study was conducted in the area of Intensive Silviculture/ TPTII of PT Sari Bumi Kusuma in Central Kalimantan. Research purposes to analyze the impact and build social economic activities from TPTII silvicultural systems in the scope of carbon trading. The results of the analysis showed that the increase of TPTII activities lead to the increasing recognition of indigenous people and make condusive certainty of the business. However, the employment negatively correlated to the size of planting area, the minimum life needs are still at least low compared with the poverty standard of the World Bank. Based on the results of the analysis and projections indicate that scenario increasing community development/ PMDH and implementation of a continuous TPTII can press shifting cultivation growing rate of deforestation and degradation in the year to 50, as compared to no guidance of other parties and TPTII activities. In term of Carbon Conservation that community love to plant attractively is rubber, meranti and tengkawang. Compensation value for carbon conservation feasible for the community of Rp. 380.000/month/family. To involve the community directly in conservation activities in the carbon framework of REDD, then suggested to the program within the community, increasing the number and skills of communities and local labor, desimination activities of TPTII to the community, and providing a compensation fund can be derived from the DR/Reforestation Fee or other source of funds. Key words: Customary recognition, conflict, business certainty, carbon conservation, compensation
