Abstract

Climate Change and global warming have brought some policy to reduce the impacts by adaptation and mitigation strategies. One adaptation strategy is to increase land use size in agriculture area base on community participation. On the other hand, sustainable development needs cooperation mainly on common investment. The aim of the study is to identify the land utilization process, role model and level of participation on customary land. We use observation and deep interview method to analyze this study. The result shows that the customary land utilization process has realized through public deliberation with local Fig.s. The agriculture programs operated with Wanatani concept or agro-forestry by housewives where multi-level strategy is mutually beneficial. Around 30 housewives have been participating in producing agriculture products, i.e., coffee, milk candy, palm sugar, and ginger powder. The level of participation especially for female farmers at RW 01, which shows a percentage of 16.6%. Generally, community participation has encouraged the gotong-royong model while has to contribute in their time, tools and materials to develop the communal shed. In conclusion, the land tenure system has taken with sharing benefits between local government & farmers. The customary tenure has recognized as one of the tenure systems in Indonesia, especially on Adat land management.

Abstract

Simple and complex agroforestry systems can be implemented simultaneously in the cultivation area within the Upper Kampar River Basin. Based on the ArcSWAT simulation results, the surface runoff (Qsurf) was estimated to be 37.20 mm, which is significantly lower than the existing land use runoff in 2014, which was 102.12 mm. This forms the basis for implementing simple agroforestry and complex agroforestry systems in the Upper Kampar River Basin. The plant species that can support these agroforestry systems are selected based on the principles of land conservation and the suitability of local plants in the Upper Kampar Watershed environment. Four types of filler plants are considered: coffee and cocoa for the simple agroforestry system, and gambier and ambon bananas/kepok bananas for the complex agroforestry system. These plant species are the most dominant filler plants in the Upper Kampar Watershed. To optimize the land with these filler plant species, analysis is conducted using Quantitative Methods (QM) for Windows 4 software based on objective functions and constraint functions. The analysis determines that coffee is suitable for the simple agroforestry system, while gambier is suitable for the complex agroforestry system. Before land optimization with the planting of coffee, cocoa, gambier, and ambon bananas/kepok bananas, the net profit is estimated to be IDR. 359,113,963,811.06. After optimizing the land and developing it with the suitable filler plant species, only coffee and gambier are planted, while cocoa and ambon bananas/kepok bananas are planted according to the available area. As a result, the net profit increases to IDR. 951,426,300,000, with an economic value increase of IDR. 592,312,336,188.94 per year.
