Abstract

Tujuan penelitian adalah menganalisis respon para pemangku kepentingan di daerah terhadap kebijakan Hutan Tanaman Rakyat. Penelitian menggunakan metode pendekatan kuantifikasi data kualitatif. Lokasi penelitian ditentukan secara sengaja dengan pertimbangan tingginya potensi pengembangan kegiatan HTR, yaitu di Provinsi Kalimantan Selatan dan Riau. Hasil penelitian menunjukkan bahwa masyarakat di Kalimantan Selatan, khususnya mereka yang telah terlibat dalam pengembangan tanaman kehutanan memiliki minat yang tinggi untuk menjadi peserta program HTR. Sedangkan masyarakat di Riau kurang berminat terhadap program penanaman tanaman kehutanan, disebabkan adanya pengalaman buruk di masa sebelumnya. Para pemangku kepentingan di tingkat kabupaten yang terdiri dari pihak pemerintah daerah dan swasta menyambut baik program tersebut, dan mendukung terselenggaranya program sebagai upaya peningkatan kesejahteraan masyarakat sekitar hutan. Berdasarkan hasil analisis stakeholder diketahui bahwa terdapat sejumlah pemangku kepentingan di daerah yang memiliki posisi dan pengaruh penting untuk keberhasilan program. Hal ini berimplikasi bahwa para pengambil kebijakan di tingkat pusat harus mempertimbangkan aspirasi mereka untuk mewujudkan keberhasilan program HTR.

Abstract

Commmunity Plantation Forest is Indonesian government policy which needed participation and responsibility from local community to manage production forest sustainability. Studies on capacity of community as prominent agent are needed. The objectives of this study are: (1) to assess the physical capital, human capital and social capital of communities and to identify their participation in HTR program; (2) to analyze the correlation between physical capital and human capital with elements of social capital, and between social capital with their participation in HTR; and (3) to develop implementation strategy of HTR. Analysis of data used descriptive method, Spearman rank correlation, SWOT and QSPM. Necessary information for this study came from a survey of 81 households from Taman Bandung, Seko Besar and Lamban Sigatal villages in Sarolangun Regency, Jambi. The results showed that physical capital, human capital and social capital are included in medium category. No correlation between physical capital and social capital, but there are correlation between social capital and human capital and participation. The study also showed that selected strategy in HTR implementation are: (1) accommodate exiting community models in forest land as community motivation; (2) optimize local government support to accelerate license process, assistance, and intensive socialization about HTR; and (3) use timber scarcity issues and PT Samhutani as market opportunity issues to stimulating community to plant timber.

Abstract

The procurement of good quality seeds for the development of mindi (Melia azedarach L.) in the community forest is absolutely necessary. The purpose of this research is to investigate the diversity of the viability and seedling vigor of mindi from different populations with various treatments of dormancy breaking. The sample materials were mindi seeds that were collected from 6 locations (6 seed lots) or seed sources which were located in the community forest of West Java. There are 10 treatments of dormancy breaking that were applied in this study. The experiment design was Randomized Complete Design (RAL). The breaking dormancy  was focused to the delignification of hard seed coat.  Results showed that the most effective dormancy breaking for mindi seed was soaking in consentrated Sulfuric Acid (H2SO4) as long as 30 to 45 minutes. The first count for germination of mindi was on the 16 day and the final count was on the 31 day.The average value of germination percentage (DB) for all seed sources was 40 %, while the highest which is 60% was mindi from Sumedang seed source. The highest value of germination rate that is 6,543%/etmal was seed  from Sumedangand seed from Gambung was the lowest (1,400 %/etmal). Keywords : community forest, Melia azedarach L., variation, viability, vigor.

Abstract

Combination of cultivated plants conducted in RHLP program in Cikanyere village enable for differences response occurrence to main plant growth. The purpose of this research is to examine the main plant growth of Gmelina arborea Roxb. in several agroforestry patterns in Cikanyere Village, Sukaresmi District, Cianjur Regency. Main plant growth parameters (height, diameter and crown projection) measured in the census in each agroforestry patterns. Physical and chemical soil analyzed from each agroforetsri patterns in the laboratory. Traced the history of land management by conducting interviews with managers of farmers each selected agroforestry patterns. The data obtained were analyzed descriptively. Agroforestry pattern wasa developed by the farmers is AF 1 (Gmelina, corn, cassava, banana), AF 2 (Gmelina, corn, coffee, bananas), AF 3 (Gmelina, mahogany, cassava, petai), AF 4 (Gmelina, mahogany, corn, chili peppers) and AF 5 (Gmelina, mahogany, dry land rice, cassava, corn). The pattern of AF 3 has the lowest of growth, while the pattern of AF 1  and AF 4 showed the most growth compared with other patterns. The pattern of AF 3 have small LCR and LAI, while the pattern of AF 1 and AF 4 have the largest LCR and LAI so that photosynthesis function optimal and main plant growth are better than the other patterns. The phosphorus (P) on the pattern of AF 3 suspected to be a limiting factor for plant growth gmelina. P and K needed cassava plants in sufficient numbers to form the root and tuber enlargement so that suspected as the cause of the low content of P elements in AF 3 pattern. Basic plant growth G.arborea Roxb. influenced by the interaction between components and land management systems that do farmers in each agroforestry patterns.

Abstract

Previous study found thar Jarak pagar  has potency for fuel break in forest fire control. There are some requirements for vegetation to be fuel break. One of the requirement as fuel break is decomposition race in which the higher decomposition rate may be suitable for fuel break in order to prevent surface fuel accumulation. A study was conducted to analyze decomposition rate of Jarak pagar in the field. Some sample plots were established in forest plantation area of Gunung Hambalang Bogor managed by Perhutani under agroforestry system. The study revealed that Jarak Pagar in the study area has higher decomposition rate when compared to other tree sppecies. Therefore, Jarak Pagar meet the requirement for fuel break from decomposition rate point of view.

Abstract

One of Forest and Land Participatory Rehabilitation Program (RHLP) is the implementation of agroforestry system. Agroforestry chosen as the solution of optimal land utilization so it would provide additional output value of either physical or financial results.This research aims to study more the growth of Sandalwood (S. album) as primary tree in some agroforestry.  Field activities done at Sanirin Village, Balibo Sub District, and Bobonaro District. The observed dimensions of main crop were height, diameter, length and width of the tree canopy. Biophysical environmental conditions of soil properties and tree canopy closure were also observed. Data was taken from several agroforestry patterns. The data then analysed descriptively to the growth parameters of main crops associated with the pattern of developed agroforestry and its management techniques. There are there types of agroforestry pattern, named AF1, AF2 and AF3. Each of AFs has combination of crops such as AF1 combination of S. album,Tectona grandis L., Sweteniasp., Aquilarium sp., Cajanus cajan, Zea mays, Cucurbita pepo, AF2 combination  S. album,Sesbania sp., Cajanus cajan, Zea mays, Cucurbita pepo and AF3 is combination of S. album, Tectona grandis L., Swetenia sp., Zea mays, Manihot utilisima. The AF3 has worst performance in height and diameter growth, while AF2 is having best performance in height and diameter growth. In the crown covered, the AF2 type is gained highest percentage compared to the others. The results showed that the growth of primary tree in agroforestry pattern to produce cassava is the lowest thanto the others .The availability of P and K elements suspected to be the cause of low growth of primary crop. Land management activities are only focused on the productivity of agricultural crops caused the crops and the main crop is uneven.

Abstract

The need for teak wood processing in Indonesia is still high both for domestic demand and export wood demand. But the shortage of teak wood demand can give opportunities for people to cultivate teak on their privately land. The purpose of this research is to examine the main plant growth of teak (Tectona grandis Linn F.) in small scale private forest and compare it with teak’s growth from monoculture forest at Perum Perhutani KPH Sumedang in same ages. The main data of plant dimensional were taken with census method from teak plants in each of the selected land such as height, canopy diameter and canopy projection. In this research, soil parameter observed consist of physical and chemical content of soil  samples  from  each  selected  land  then  analyzed  in  laboratory.  Crown  closure  data  taken  by  using  a  spiracle     densiometer. The history of land management known by interview with farmers in each selected land. Those data were analyzed descriptively.            The results showed that the observed forest have 3 (three) different age classes of teak plantation. They are teak plant with  class  age  of  3  years,  6  years,  and  12  years  whom  the  growth  of  teak  are  different  in  those  parameter  such  as diameter, height, crown closure and basal area. Growth of teak plantation in the village of Babakan Asem is a plant with  the best teak growth among the other villages. Their growth maybe influenced by several factors, that is  the condition of the site or soil condition factors and cultivation activities. The result of crown closure show that the majority of sunlight blocked  by  the  crop  canopy  of  teak,  so  less  than  40%  of  sunlight  can  reach  the  soil  surface.  That  condition  maybe affected by size crop of teak and the distance between teak plantation it self. The result of soil analysis indicated that  physical and chemical soil content in Conggeang District are impact on teak growth which bulk density, water storage, KTK, pH, and other chemical substance are related to teak diameter’s  growth.             Growth  of  teak  plantation  between  small  scale  private forest  and  Perum  Perhutani  were  significantly different  in class  ages of  3 and 12 years  and didn’t  different  at  class ages of  6 years  in diameter.  The difference in  teak growth between  small  scale  private  forest  and  Perum  Perhutani  are  caused  by  a  factor  of  using  teak  seed  and  the  forest management.

Abstract

The Influence of the Mahogany Stands (Swietenia macrophylla King.) On The Growth and Production of Jatropha curcas (Jatropha curcas Linn.)Agroforestry of mahogany and jatropha in Babakan Madang RPH was established. Jatropha were planted under mahogany stands of 3 years old (young mahogany stands), and 17 years (old mahogany stands). The difference of ages of mahogany may give influence on the growth and production of jatropha. The purpose of this research was to determine the influence of the mahogany stands (S. macrophylla) on the growth and seed production of Jatropha (J. curcas).The growth parameters of jatropha consisting of height, diameter, length, width tree crown were measured. These growth parameters were used to determine the tree crown width, as well as root length.  Jatropha curcas plant height measurement was done by using graft-scale, while for measuring the widht, length and width of the crown, band meter was used. In this case, census method was applied. In every mahogany stand, 15  J. curcas trees  were chosen for sampling. Root length of jatropha was measured by digging method. Horizontal and vertical roots were measured. The result showed that the growth of jatropha was significantly affected by the stand age of mahogany. Young mahogany stands produced better effect on height, diameter, length, width, and crown width of Jatropha than in old mahogany stnads. It was also strengthen by the results of the t-test (p

Abstract

Light Intensity, Temperature, Humidity and Rooting System of Mahogany (Swietenia macrophylla King.) in RPH Babakan Madang, BKPH Bogor, KPH BogorPlanting space in agroforestry system was one of important tree rooting was one of important factor that determine tree rooting. It was caused by the relation between planting space and light availability that could penetrate into main plant canopy and space availability for rooting. One of commonly used plant in agroforestry was mahogany which has deep rooting system and has a single main root thus could be combined with shallow rooting system plants as its understory. This research was supposed to know the light intensity, temperature and humidity in mahogany stands and to know the length and depth of mahogany horizontal root as a reference to determine suitable crop plants for that rooting condition. Observed parameters in this research were light intensity, crown coverage percentage, temperature, humidity, and length and depth of mahogany horizontal root. Research results show that light intensity value in young mahogany stands was 24.62% and in old mahogany stands was 19.17%, while crown coverage percentage in those two stands was respectively 36.50% and 84.38%. Value of that light intensity wasn’t compared caused of its different time in data collecting. Temperature in sample plot in young mahogany stands and the old ones was 28,53o C and 28,07o C, while its humidity was 75.12% and 75.23%, respectively. Length of horizontal root in young mahogany stands and the old ones was 0.68 m and 1.68 m, while its horizontal depth was 9.95 cm and 12.58 cm, respectively. Other observed parameter was tree dimension (diameter, height, and crown area), that supposed to know the growth quality of observed mahogany. Research results show that mahogany stands could be combined together with crop plant if it seen from light intensity, temperature and humidity aspects. Higher crown coverage along with the increasing of main plant (mahogany trees) has to be combined with suitable and high economic value crop plant. Some recommended crop plant for young mahogany stands are ginger and pandan, while for old mahogany stands were tuberous plant and kapulaga.
