Agroforestry systems under rules of community-based forest management support local livelihoods inÂ the Jangkok watershed, Lombok Island. One of the conditions from the forest authoritiesfor allowingÂ agroforestry system is that it should maintain forest conditions. Since 1995 the Jangkok watershed has undergone rapid land use change, especially in the forest area. These changes led to a reduction of carbon stocks and thus to emission of CO2. This research aimed to: (1) Measure the carbon stocks in several land use system within the Jangkok watershed, (2) Assess the contribution of agroforestry systems in maintaining carbon stocks and reducing emissions. The assesment was performed based on the RaCSA (Rapid Carbon Stock Appraisal) method using three phases: (1) Classify land use change applying TM5 Landsat Satellite images for the period 1995-2009, (2) Measure carbon stock in the mainÂ land uses identified, (3) Quantify the contribution of agroforestry practices. Results showed that (1) The total amount of carbon stock at Jangkok watershed (19,088ha) was 3.69 Mt (193 Mg ha-1); about 23% of this stock found in the agroforestry systems (32% of the area),(2) Gross CO2 emission from the Jangkok watershed was 8.41 Mg ha-1 yr-1, but due to the net gain in agroforestry of 2.55 Mg ha-1 yr-1 the net emission became 5.86 Mg ha-1 yr-1 Â Keywords: Â agroforestry, carbon stocks, carbon emission rate

ABSTRACTThe area around Jangkok watershed has changed, dividing it into some land use systems. This research aimed to study the effect of plant species diversity onC-stocks, and to analyse the characteristics of land use systems based on their similarity. The observations were carried out on 18 plots representing six land use systems in Jangkok watershed (Lombok Island) i.e. primary forest (PF), disturbed forest (DF), Mahogany- woodlot (MW), candlenut- agroforestry (CA), multistrata- agroforestry (MA), and simple- agroforestry (SA).The species diversity level was measured using Shannon-Weiner diversity index, whileC-stocks according to the method of RaCSA (Rapid Carbon Stock Appraisal). Results showed that forest conversion to agricultural land usesreduced the number and density of the species, average wooddensity andtree basal area. The PF represented the highest biodiversity index (3.46), while the other land uses were categorised in medium and low. Largest C-stock wasfound inPF and in(30 years old) of MWaveraged of 500 Mg ha-1, while the lowest was in SAof 68 Mg ha-1, while in other land uses was 219 Mg ha-1.The quantity of C-stock was not related tospecies diversity and its density, but closely related (pof tree (R2=0.84), basal area of all sizes tree (R2=0.86), and with the basal area of big trees (diameter > 30 cm) (R2=0.71). Based on the number and species density, agroforestry system (MA and CA) resembled the characteristics of natural forest (DF and PF)./spanEN-GBspan style=

Fidusia merupakan pengalihan hak kepemilikan suatu benda atas dasar kepercayaan dengan ketentuan bahwa benda yang hak kepemilikannya dialihkan tersebut tetap dalam penguasaan pemilik benda. Objek jaminan fidusia dapat disita oleh negara jika digunakan untuk melakukan perbuatan melawan hukum. Seperti kasus yang menimpa PT Astra Sedaya Finance, sebagai perusahaan pembiayaan yang merasa telah dirugikan akibat benda jaminan fidusia yang disita negara dari tangan pemberi fidusia selaku debitur karena yang bersangkutan melakukan perbuatan hukun kejahatan llegal logging.yang mengakibatkan benda objek jaminan dirampas oleh negara. Perampasan yang dilakukan oleh negara terhadap objek jaminan dalam kasus illegal logging ini tidak bertentangan dengan droit de suite yang dimiliki penerima fidusia. Hal ini dikarenakan dengan adanya sifat droit de suite tersebut perusahaan pembiayaan sebagai penerima fidusia tidak kehilangan haknya untuk menuntut pelunasan utang pemberi fidusia apabila pemberi fidusia wanprestasi. Perlindungan hukum bagi kreditur dalam hal benda jaminan dirampas oleh negara, dapat diuraikan sebagai berikut bahwa, (1) debitur wajib menyediakan jaminan pengganti yang setara nilainya dengan barang yang dirampas oleh negara; (2) mewajibkan kepada debitur (pemberi jaminan fidusia) supaya melunasi utangnya.

The Sesaot forest area has been managed by the community through the Social Forestry scheme with an agroforestry system. The objectives of the study were to identify the diversity of agroforestry patterns, analyze incomes on various agroforestry patterns, analyze the amount of carbon stock and analyze the most optimal agroforestry patterns. The method used is descriptive through a series of observations, interviews and Focus Group Discussions, to 42 respondents and measurement of carbon stocks in 18 farmer locations. Analysis of agroforestry patterns was carried out by making clusters based on plant dominance, analyzing the amount of carbon using allometric equations and analyzing the optimal value of agroforestry patterns using scoring. Based on the results of the study, it can be concluded that: there are four agroforestry patterns in the Sesaot Forest Area, namely, candlenut dominant agroforestry, mahogany dominant agroforestry, mixed agroforestry and simple agroforestry. The largest income was obtained in the mixed agroforestry pattern and the smallest was in the mahogany dominant. Meanwhile, the largest amount of carb on stock was found in the mahogany dominant and the smallest was in the simple agroforestry. The results of the scoring analysis show that mixed agroforestry practices are in the most optimal category compared to other agroforestry patterns.

This research was intended to find Contribution of Non-Timber Forest Products Candlenut (Aleurites Moluccana) to Farmer’s Income of Tangga, supporting and inhibiting factors, and income improvement strategy of business non-timber forest products candlenut. The research location in Tangga hamlet, Selengen Village, Kayangan District, North Lombok Regency, West Nusa Tenggara Province. This research used interview method with questionnaire tool to 36 respondents was carried on February 2018. The results showed Contribution of Non-Timber Forest Products Candlenut from region farmer community to farmer’s income was 63.2% /area of arable land or 63% /hectares, which support farmers to cultivate candlenut because it is very easy to develop, does not require intensive maintenance, harvest activities were very easy to do, technology tools used were traditional, and marketing process was easy to do. As well as barriers in the miscellaneous management of the lack of capital and the availability of limited tools in the processing of candlenut so that farmers can only sell candlenut in the form of logs that will reduce the income it receives, as well as the lack of knowledge and skills possessed by farmers. Income-generating strategy of the candlenut can be done with SO strategy (Strenght-Opportunity) that is developing the potency of candlenut with skill owned by farmer by utilizing simple tool technology. As well as increased cultivation and intensive candlenut intensive maintenance by utilizing the existing land area.

This research aims to (1) analyze the pattern of ecotourism management in Gili Lawang based on the concept of CBT (Community based tourism) according to Demartoto (2009) and (2) analyze supporting and inhibiting factors that affect the involvement ofcommunity in managing ecotourism. The research was located in Gili Lawang ecotourism area, Sugian Village, Sambelia, East Lombok Regency. This research used descriptive qualitative method, by using literature reviews data collection method,interviews, and observations. The number of respondents involved were 14 respondents. Data analysis that was used is descriptive analysis. The result of this research showed that the management pattern of community based ecotourism in Gili Lawang has not fully implement CBT (Community based tourism) concept since the involved community has not been included in evaluator aspect. Supporting factors that affect the involvement of the community in managing ecotourism is the potential of tourism that can be developed into tourism attraction, the desire of the community to preserve the nature, and to grow the economy surrounding the tourism area. Meanwhile, the inhibiting factor that affect the involvement of the community in managing ecotourism is the lack of education of the community regarding the development of ecotourism area and the lackof awareness of the community regarding the importance of their involvement in developing tourism area. Besides that, another inhibiting factor is the lack of government’s concern to make approach to the native community to show how importantcommunity based tourism is.Keywords: Ecotourism, management pattern, involvement factor
