Strategi Pengelolaan untuk Pengembangan Hutan Rakyat di Kecamatan Rancakalong, Kabupaten Sumedang (Management Strategy for Private Forest development in Rancakalong District, Sumedang Regency)

Wood is one of the natural resources needed by humans. The high growth rate of the human population causes an increase in demand for wood.  Currently, one of the largest timber producers in West Java is private forests. Fulfillment of high demand for wood should be balanced with good management, so that is not to threat private forest sustainability. One of the areas with the private forest that is still actively undertaking private forest management activities is in Rancakalong District, Sumedang Regency. This study aims to identify the current management practice of private forests and to formulate sustainable development strategies. The data was collected through questionnaires and interviews, field observation, and secondary data collection. The respondent number of private forest farmers was 98 respondents. Snowball sampling techniques were used to interview government officials, middlemen or wood dealers. The analysis results at the input have an internal total score of 2,7, which shows the condition is at the medium stage and external total score of 3,17, which shows the public response to threats and opportunities are strong enough. At the matching stage, the result is that the management of private forest is the second quadrant, which means that the private forest is entering the growth stage. The study result shows that the first priority to be implemented in the Rancakalong private forest is to establish farmer organizations.Keywords: private forest, management, strategic, Rancakalon

Designing Wildlife Corridor Along Cikapundung River in Bandung Urban Area (Indonesia) based on Comparation with Kamo River in Kyoto (Japan)

Cikapundung is a river connecting wildlife habitat in two open green space areas; there are Tahura Djuanda and Bandung Zoo. Now, these habitats are fragmented due to intervention by urban activities in the Cikapundung River boundary. One of the proposed solutions is to develop a wildlife corridor along the Cikapundung River. The purpose of this study is to identify the landcover of the Cikapundung River, analyze the potential area which can be developed into a wildlife corridor, designing the landscape of the corridor tailored to the needs of the wildlife, and comparing the condition of the Cikapundung River boundary with Kamo River in Kyoto, Japan. Primary data is landcover of Cikapundung River boundary obtained through on-screen digitizing from satellite imagery using ArcMap. Secondary data are the biodiversity list in Cikapundung River riparian area and its ecological description. Cikapundung River border has several land cover types; the highest percentage of the landcover is tree canopy 62.2%, followed by buildings 31.0%. As a result of the comparison Cikapundung River has a more significant vegetation species; however, Kamo River has a more significant number of wildlife species. In the design planning, 14 vegetation species have been selected according to 26 target wildlife species' needs.&nbsp

Metode Survei Kayu Rakyat Berdasarkan Karakteristik Sosial Ekonomi dan Biofisik Kawasan: Studi Kasus di Kabupaten Bogor (Survey Method for Timber Stand of Private Forest based on Socio-economics and Biophysical Characteristics: a case study in Bogor Dis

The objective of this research is to determine the appropriate survey method for timber stand of private forest, based on its important characteristics. There were three methods used in this research, namely, method according to basic data i.e social-economics and biophysic data; method based on image, approached by vegetation transformacy using NDVI; and method based on integration of basic data and image. The result showed that basic data method is the best method for stratification of the village (desa), as a primary sampling unit of the private forest population (district). The second ones is basic data and image-integration method and last ones is image method.Keywords : basic data, coefficient of variation, image, NDVI, private forest, survey method, timber

Estimation Model of Ramin (Gonystylus bancanus) Standing Stock in Peat Swamp Forest: Case Study in Sumatra and Kalimantan

Multiple sampling technique was applied to estimate ramin (Gonystylus bancanus) standing stock in peat swamp forest by combining imagery analysis (phase I) and field measurement (phase II). The objectives of this research were to obtain (1) estimation model of stand volume, (2) estimation model of G. bancanus standing stock, and (3) volume of standing stock of G. bancanus in Sumatera and Kalimantan peat swamp forests. The research was conducted in peat swamp forest of Sumatera and Kalimantan Island. ALOS AVNIR image interpretation was completed to obtain crown density and used as independent variable for developing stand volume model. Cluster sampling was used to obtain field data from circle sample plot of 0.1 ha and square sample plot of 0.25 ha. Spatial analysis was conducted to map and calculate standing stock of G. bancanus for Sumatera and Kalimantan Island. Estimation model of stand volume was V bf = 0.1851 C field1.05234 (R 2 =0.62) for Sumatera peat swamp forest and V bf = 3.1163 e 0.041 Cfield (R 2 = 0.62) for Kalimantan peat swamp forest, respectively. We estimated that standing stock of G. bancanus of peat swamp forest in Sumatra and Kalimantan was 5% and 2.3% of the total stand volume, respectively. Base on both the estimation models, standing stock of G. bancanus in Sumatera peat swamp forest was 15,351,063 m 3 and in Kalimantan peat swamp forest was 6,004,874 m 3

KELAYAKAN USAHA BUDIDAYA IKAN NILA DI DESA CIBUNAR KABUPATEN SUMEDANG: SEBUAH ANALISIS KEBERLANJUTAN

Tilapia from small-scale farms has a low level of business sustainability due to high energy and financial investment. This study aims to analyze the business feasibility and sustainability status of tilapia cultivation in Cibunar Village, Sumedang Regency, This study uses a survey method for 100% of the existing population (16 respondents). Business feasibility is determined by calculating the investment feasibility analysis (NPV; IRR; PP and B/C Ratio) and the sustainability status analysis is carried out using the RAPFISH-MDS method. The results showed that the tilapia fishery business was feasible to run as a business seen from the NPV (Net Present Value) of Rp36.297.168; IRR of 27.70%; Net B/C Ratio 1,51; and PP (Payback Period) at 3 years 11 months 24 days, BEP/BEP production (units) of 151,65 kg and BEP (Sales) of Rp 4.549.373,48. The value of the sustainability index of tilapia cultivation based on the ecological dimension is 75,37 (very sustainable); economic dimension 55,27 (sufficiently sustainable); institutional dimension 33,49 (less sustainable); social dimension 46,94 (less sustainable) and technological dimension 13,7 (unsustainable). The sustainability status of tilapia aquaculture in Cibunar Village, Sumedang Regency, in a multidimensional manner is 44,85 (less sustainable)
