ABSTRAK Pengeloaan Kebun Raya Baturraden di Kawasan Hutan Produksi terbatas dapat menimbulkan permasalahan surface run off apabila penanganan lokasi tidak dilakukan secara konservatif. Penelitian ini bertujuan untuk mengatasi problematika Perubahan ekositem Hutan Produksi Terbatas yang bersifat homogen menjadi Kebun Raya Baturraden merupakan hutan heterogen. Dengan cara membuat PU (Petak Ukur) di zona pemanfaatan keluasan 77,4 Ha, sebanyak 109 PU (Petak Ukur) dengan ukuran 20x20 m, intensitas 5,5, jarak antar PU 1, 3 m. Hasil pengamatan parameter yang menjadi pertimbangan ketinggian tanah antara 1076-760 Dpl, kelerengan tanah 12⁰-30⁰, kedalaman tanah < 85 Cm – 90<, erodibilitas tanah 0,43, jenis tanah Latosol Coklat dan curah hujan rata-rata 5.600 mm per tahun. Dari hasil pengamatan kawasan Kebun Raya Baturraden tanah mudah sekali terjadi proses surface run off. Mengatasi dan merubah ekosistem dari hutan homogeny menjadi heterogen (1) penjarangan harus bertahap sesuai lahan yang akan dikelola, (2) Dengan kondisi tegakan pohon sangat rapat untuk melakukan tebangan sebaiknya menggunakan tebangan penerangan atau penjarangan jangan sampai tanah terbuka mengingat mempunyai curah hujan rata-rata 5.600 mm per tahun. (3) pada lokasi tertentu yang rawan terjadi erosi harus dibuat terasering untuk mengurangi terjadinya surface run off. Kata Kunci: Kebun Raya, Hutan Produksi terbatas surface run off, ekosistem ABSTRACTManaging Baturraden Botanical Garden in the Limited Production Forest Area can cause problems of surface run off if the location is not handled conservatively. This study aims to overcome the problem of ecosystem changes of the homogeneous Limited Production Forest to become Baturraden Botanical Garden which is heterogeneous forest by making PU (sample plots) in the utilization zone of 77.4 hectares in breadth, a total of 109 PU (sample plots) with a size of 20x20 m, intensity of 5.5, the distance between PU’s 1, 3 m. The parameters taken into consideration, as a result of observation, are the height of land between 1076-760 above sea level, land slope between 30⁰ 12⁰, land depth <85 cm - 90 <, soil erodibility 0.43, Brown Latosol soil type and an average rainfall of 5,600 mm per year. From the observation of Baturraden Botanical Garden area, it was observed that land surface run off processes easily occur. To overcome and change the ecosystem of the forest, from homogeneous to heterogeneous: (1) thinning should be phased in accordance to the land to be managed, (2) with the condition of very tight tree stands to be felled, lighting felling or thinning should be done without exposing the land considering the rainfall average of 5,600 mm per year. (3) In certain locations that are prone to erosion terracing must be made to reduce the occurrence of surface run-off. Key words: Botanical Garden, limited production forest, surface run-off, ecosystem.Cara sitasi: Mandiriati, H., Marsono, D., Poedjirahajoe, E., Sadono, R. (2016).

Cajuput is a plant that plays an important role for forest industry development. Its leaves contain essential oil and become one of the non-timber forest products. The productivity of cajuput leaves is affected by certain factors, one of them are the level of land suitability. This study investigated the land suitability for cajuput establishment and its inference on silviculture strategy. Study location was situated in Forest Resort Gubugrubuh, Gunungkidul District. Data collection was conducted in 3 site that converted as the priority site of cajuput plantation namely site 75, site 78, and site 80. We used 6 indicator of land attributes including altitude, slope, rainfall, temperature, soil acidity, and soil organic carbon. The assessment of land suitability was determined by qualitative approach using storie and root square method. The result showed the level of land suitability was classified into N1 (currently not suitable) referring to the storie method, meanwhile it was categorized into S3 (marginally suitable) according to the root square method. This study also discovered the distinctive land attributes which became the limiting factors of cajuput growth in each site. The best silviculture strategies for supporting cajuput development in each site were terrace construction, plant distance management, and fertilization.

Small-scale Privately-owned Forest (SSPF) has various patterns identification, based on the stand structure and species composition. The recognition and classification of the SSPF cropping patterns are required for further planning and policy development. Therefore, this study aims to classify the cropping pattern of SSPF in Ciamis Regency, West Java Province, Indonesia. The data were collected by observing the stand structure and species composition of 150 plots of land, encompassing three Sub-districts representing the central, northern, and southern regions of Ciamis Regency. The four categorical variables include tree species composition, age, spatial distribution, and intercropping pattern. While the two continuous variables were stand density and basal area. The patterns obtained were classified based on a Two-Step Cluster algorithm with log-likelihood distance measure, and auto clustering using Schwarz's Bayesian Information Criterion, validated by silhouette index. In addition, a multicollinearity test was conducted to reduce redundancy in using variable sets. The results showed that, the improvement of the cluster quality based on the silhouette index value, was achievable by excluding the tree spatial distribution variable, which exhibits multicollinearity. The cropping patterns were classified into three categories, namely tree crops, mixed-tree lots, and agrisilviculture for group-1, group-2, and group-3, respectively. Group-1 consisted of stands with one or two commercial tree species, and in several cases, were intercropped. Group-2 contained uneven-aged mixed-tree stands without any crops. While Group-3 consisted of an intercropping system of uneven-aged mixed-tree stands and crops. The results suggest further analysis, in order to relate the cropping patterns with the socio-economic characteristics of the landowners, as well as the strategies for the development of a sustainable SSPF.

A precise and accurate energy production quantification, particularly at the individual tree level is needed to understand the potential contribution of eucalyptus plantations to renewable energy development. However, measuring energy storage with a destructive method is inefficient because it requires a large amount of resources. The development of allometric equations is a realistic solution to solve this problem as it facilitates the efficient estimation of energy production from trees. Therefore, this study aims to develop an allometric equation for estimating the energy production of Eucalyptus urophylla in dryland ecosystems in East Nusa Tenggara. The destructive sampling was carried out on 25 sample trees which are evenly distributed from small to large dimensions, while the calorific value of each tree component was analyzed using the bomb calorimeter method. Furthermore, the energy production of each tree was counted by multiplying the calorific value with the total biomass accumulation. To develop an allometric equation, the analysis of regression was applied using several independent variables, such as diameter at breast height (D), combined squared diameter of breast and tree height (D2H), as well as D and H separately. The results showed that the energy production of E. urophylla at the study site varied from 252.56 to 7,813.30 MJ tree-1 with more than 90% accumulated in the stem, followed by foliage (4.62%) and branches (4.05%). The higher the tree dimension, the greater the energy production. Moreover, the equation lnŶ = lna + b.lnD + c.lnH was the best allometric model to estimate energy production with an accuracy of 95.2%. Based on the results, the allometric equation provides an accurate estimation of energy production in E. urophylla.

Vegetation is one of the important biophysical components of ecosystems in landscape-based conservation area management. The purpose of the study was to identify the composition and structure of the vegetation in the Upper Cisanggarung watershed area of the Mount Ciremai National Park. Data were collected through vegetation analysis using the double plot method with systematic sampling on various types of land cover. Data analysis was done by quantitative descriptive. The results showed that the composition of the number of species in the plantation forest land cover type was higher than the natural forest and shrub land cover types. The total number of species found in all research areas is 94 species. Based on the horizontal stand structure, all land cover types approach the shape of the inverted J distribution (negative exponential), with the horizontal stand graph of plantation forest being at the top position, followed by natural forest and at the bottom being shrubs. Furthermore, plantation forest cover has the highest species diversity index and species richness index at the growth rate of seedlings to poles compared to other land covers, while for the tree level the species diversity index and the highest richness index are owned by natural forests.

Crown Model on Several Family of 9 years old of Teak (Tectona grandis L.f) Progeny TrialCrown plays an important role in regulating the rate of tree growth through the photosynthesis process. Furthermore it can be used to measure stand density and to determine the availability of growing space. Because of the difficulty and time consuming in direct crown measurement, the development of crown model is needed. The objectives of this study were to develop crown models of teak (Tectona grandis) of 9 years old from selected open pollinated families and to identifi) the variations of crown models among them.The study was conducted in an open pollinated progeny test located at the compartment 49a, RPH Sidowayah, BKPH Kedunggalar, KPH Ngawi. The experimental unit was family. Five families with the best average of stem diameter at breast height were selected as samples. Crown models were developed and variations of crown model were tested with analysis of variance.The crown model of teak can be divided into two sections. The upper crown representing the light crown section followed parabolic model while the under crown representing the shaded crown section followed linear model. No differences in crown model were found among families. The proposed models are:light crown section, paraboloid : Rl =1.91 * hl0.33shaded crown section, linear .. Rs = -0.75 + 0.57 hswhere Rl is light crown radius (m), hl is the height of light crown section (m), Rs is shaded crown radius (m) and hs is the height of shaded crown section (m)
