The rural communities living around the National Park are generally farmers. They are less empowered and classified as poor. This is due to the relatively low capacity of farmers. In order to be more empowered, the farmers need to improve their capacity. This study aimed to analyze the factors that directly and indirectly affect the capacity building of agroforestry farmers around the National Park. This study was conducted in Kuningan and Majalengka districts of West Java Province for four months, from July to October 2017. Sampling technique used was random sampling with cluster location was agroforestry Forest Farmer Group (FFG) in the buffer zone of Gunung Ciremai National Park. The sample size was 310 members of agroforestry Forest Farmer Group. The results showed that the capacity of agroforestry farmers around the National Park was low. This is due to the low level of formal education, farming experience, cosmopolitan level, and narrow farmland of farmers. It is also caused by low environmental support factors (economic accessibility, ecological conditions, FFG role) and low participation of farmers in agroforestry both economically and socially.

Parkia timoriana (DC) Merr (popularly known as tree bean) is a leguminous tree species found distributed in several South-East Asian countries like Indonesia, Japan, Malayasia, Phillipines, Thailand, Vietname including the mid and foothills of eastern Himalayas. We identified the seed source of this species and grouped them into different agro climatic zones based on moisture index and precipitation. The resultant agroclimatic zones were analysed for significant influences on quantitative traits of seeds and seedlings of P. timoriana and their contribution to germination and growth. Analysis of variance showed significant variation (p humid > subhumid > perhumid. We recommend tree breeders to chose of P. timotiana from arid zone (MI = -20 to -60) for establishing seed orchard for optimum yield. Further, ARCGIS interpolation tool could be of use for predicting better seed source of this species in plantation programmes.

Perspective difference of users related to forest area utilization has caused tenurial conflicts, as well as, possible utilization conflicts. This study aimed to understand stakeholders’ interests and influences as exogenic factors that caused the non-optimal institutional performance. This study used an institutional diagnostic approach to understand how the situation and action arena is from inter-influencing institutional entities. Data collection used the convergent parallel mixed method (CPMM) approach, while analysis used the rapid land tenure assessment (RaTA) method. Further, this study used the Institutional Analysis Development (IAD) method to explain how the exogenic factors influence each other. The results showed that the characteristics of biophysical attributes, community attributes, as well as, rule in use were inter-influencing within the action arena. Besides, based on the post-prospective analysis result, policy decision opted by the government tend to not consider the community existence, who have been using the land for their livelihood. This situation has caused utilization conflicts between communities and concession holders. Thus, this study recommends: 1) the stakeholders to establish a communication forum for all parties to obtain clear information about forest utilization and to support institutional performance; 2) institutionalizing local community to govern forest utilization, and 3) determining management and concept of sustainable forest, as well as, policy making.

Soil macro fauna is one of the bio indicators in determining the quality of the land. The total soil macro fauna is influenced by the climatice condition and land utilization pattern. Agroforestry is one of type land utilization that is expected to improve the soil fertility. Land utilization changing from monoculture into agroforestry is predicted to influence the soils macro fauna. This study is aims to find out the population of soil macro fauna before and after applying manglid agroforestry. The research was conducted in Cukangkawung, Tasikmalaya District, West Java Province. Sample of macro fauna was taken from non-productive land of tea plantations and one year after the land was planted by manglid + corn + peanut by using agroforestry. Samples were taken in Feb-March 2015 and once more in Feb-March 2016. The observation land area is 1 hectare that is divided into 1 m x 1 m - 16 observation plots that was placed randomly. In each plot, a hole of 30 cm in depth was made and the dug out soil was placed on the plastic container. The collected macro fauna was counted and placed into a bottle that was filled with 70% alcohol. The macro fauna identification was conducted in LIPI zoology laboratory. The research shows that the diversity indexes for Shanon and Margalef on manglid agroforestry are higher than on the ex tea land. Factors that influence the soil macro fauna diversity improvement is pH, low temperature of soil and high soil moisture. Soil macro fauna becomes organic decomposer in agroforestry for about 56,25% and 20% in non-productive land of tea plants.
土壤大型动物是判断土地质量的生物指标之一。土壤宏观动物总数受气候条件和土地利用方式的影响。农林业是一种有望提高土壤肥力的土地利用类型。预计土地利用由单一栽培向农林业转变将对土壤宏观动物群产生影响。本研究旨在了解混耕前后土壤大型动物种群的变化情况。该研究在西爪哇省Tasikmalaya区Cukangkawung进行。在茶园非生产用地和农林业种植芒豆+玉米+花生1年后采集大型动物区系样本。2015年2 - 3月取样，2016年2 - 3月再次取样。观测用地面积为1公顷，随机划分为1 m × 1 m的16个观测地块。在每个地块上挖一个30厘米深的洞，将挖出的土壤放在塑料容器上。将收集到的大型动物群进行计数，并放入装有70%酒精的瓶子中。大型区系鉴定在LIPI动物实验室进行。研究表明，林下农林业中香农和玛格莱夫的多样性指数高于原茶地。影响土壤宏观动物多样性改善的因素是pH、土壤低温和土壤高含水量。在茶树非生产地，土壤大型动物成为农林业有机分解者的比例分别为56%、25%和20%。

Trema is one of tropical forest trees that has many advantages such as wood for building, pulp and charcoal, leaves for medicine and bark for dye material. The constrain of the development of this species is the difficulties of the seeds to germinate and the rapid deterioration of the seeds after being stored. Therefore, there should be a right method to solve the problems. The aim of the study is to determine the proper method of priming to enhance the viability and vigor of trema seeds after storage. Randomized Complete Design was employed in this trial by priming the seeds before and after storage. The treatments werepriming methods including: control (no priming), matriconditioning with ash, osmoconditioning by soaking of 5% H 2 O 2 , humidify with water and hydrated-dehydrated process. The observed parameters were thepercentages and speed of germination. The results showed that the treatment method of priming the best for this type of Trema, both before storage and after storage hydration is the treatment of dehydration. Before storage, can increase the value of germination percentage and speed of germination respectively 15% and 0.9% /Etmal. After the storage, treatment hydration dehydration can increase 17% germination and speed of germination of 1.25% / Etmal.

Community Based Forest Management program through Pengelolaan Hutan Bersama Masyarakat (PHBM) scheme has been implemented in Perhutani forest in Java since 2001. The program has been developed to alleviate rural poverty and deforestation as well as to tackle illegal logging. However, there was very limited information and evaluation on activities of the program available especially in remote area/regencies, including Ciamis. This paper studies the socio-economic, geographical and perceptional factors influencing farmers decision to join PHBM program, farmers selection criteria for the crops used in the program, and farmer decision to allocate their time in the program. It also examines the costs and income related to the program and how the program land was allocated between different farmers groups and within the farmers groups as well as the perceptions of the state company’s (Perhutani) staff members on the program. Deductive approach was used with quantitative and qualitative methods. Quantitative data were collected through questionnaires from 90 respondents at three farmer groups from 3 villages, 30 respondents of each group respectively. Cross tabulation and descriptive statistical analysis were used to analyse quantitative data. Qualitative data were collected through interviewing of 9 key informants, three informants of each farmer group respectively, and two Perhutani’s staff. Results showed that PHBM program contributed to about 26.9% to community’s monthly income. The program introduced benefit-sharing system and accommodated community initiatives. Perhutani’s support was illustrated by freedom of choice of community in selecting the sharing area (land allocated for farmer to manage) and the planted crops. Factor influencing farmers’ decision in selecting the sharing area was geographic conditions, in selecting the crops was farmer skills, and in allocating working time was farmers’ priority.
自2001年以来，通过Pengelolaan Hutan Bersama Masyarakat (PHBM)计划实施的以社区为基础的森林管理方案已在爪哇的Perhutani森林实施。该计划旨在减轻农村贫困和森林砍伐，并打击非法采伐。但是，关于该方案活动的信息和评价非常有限，特别是在包括Ciamis在内的偏远地区/县。本文研究了影响农民加入PHBM计划决策的社会经济、地理和感知因素，农民对计划中使用的作物的选择标准，以及农民在计划中分配时间的决策。它还检查了与该计划相关的成本和收入，以及如何在不同的农民群体之间和农民群体内部分配计划土地，以及国有公司(Perhutani)工作人员对该计划的看法。采用演绎法，定量与定性相结合。通过对3个村3个农民组90名回答者进行问卷调查，每组30名回答者。定量资料采用交叉表法和描述性统计分析法进行分析。通过对9名关键举报人、每个农民组分别对3名举报人和2名Perhutani工作人员的访谈，收集了定性数据。结果表明，PHBM项目对社区月收入的贡献约为26.9%。该计划引入了利益分享制度，并接纳了社区的倡议。Perhutani的支持体现在社区在选择共享区域(分配给农民管理的土地)和种植作物方面的选择自由。影响农民选择共享区域决策的因素是地理条件，影响选择作物决策的因素是农民技能，影响分配劳动时间决策的因素是农民优先考虑的因素。

FUNGI AND MACROFAUNA COMMUNITY IN POST-FIRE PEATLAND IN CENTRAL KALIMANTAN. Peat soil with its unique physical and chemical character is host to various microbe and fauna. In the peat, the existence of microbe and macrofauna influenced by several environmental parameters. This paper investigates the fungi and macrofauna community in the post fire degraded peat swamp soil with emphasize on two points: the abundance of soil fungi and soil macrofauna and to describe the environmental parameters (e.g. understory and chemical properties) on the existence of fungi and macrofauna community. Soil dilution and pitfall trap methods were used to collect soil fungi and macrofauna in four different plots based on the revegetation time which are: no revegetation (A), 12 months after revegetation (revegetated in December 2016) (B), 21 months after revegetation (revegetated in April 2016) (C), and 24 months after revegetation (revegetated in December 2015) (D). Result showed that abundance of soil fungi obtained during this study is 4×105 to 11×105 cfu/ml. While the macrofauna abundance is 353–1038 ind/m2. Soil fungi and macrofauna community in peatland affected by understory cover which was related with revegetation activity. There is a trend of increasing the abundance of soil fungi and macrofauna on the post-fire peatland along with the increase of the percentage of understory cover.

THE UTILIZATION OF Merremia peltata FOR LIVESTOCK FEED TO CONTROL AN INVASIVE ALIEN PLANT SPECIES IN BUKIT BARISAN SELATAN NATIONAL PARK. Mantangan (Merremia peltata) is a plant species which invades the habitat of herbivorous animals such as elephants and rhinos in Bukit Barisan Selatan National Park (BBSNP) Sumatera, Indonesia. One possible way to overcome the problem is by providing M. peltata as livestock feed. This paper observes potential use of mantangan for goat feed. The study was conducted at Tampang Tua Village, a buffer zone of BBSNP where most of communities are farmers. The study and treatment were given to 6–7 months old goat breeders with an initial weight of 7–8 kg. Additional forage feed data were collected during March to June 2014. The research was designed as Latin Square Design with four treatments and four replications. The treatments consisted of four formulations: treatment A (field grass), B (field grass + 200 g mantangan), C (field grass + 400 g mantangan), and D (field grass + 600 g mantangan). Field grass is available continuously (ad-libitum). Result shows that the treatments significantly affect feed consumption level (P <0.05), but it did not have significant effect to body weight (P> 0.05). In other words, mantangan is potential for animal feed. This research was conducted as an effort to manage invasive alien plant species by utilizing mantangan as feed for livestock.

Result shows that the treatments significantly affect feed consumption level (P <0.05), but it did not have significant effect to body weight (P> 0.05). In other words, mantangan is potential for animal feed. This research was conducted as an effort to manage invasive alien plant species by utilizing mantangan as feed for livestock.","PeriodicalId":13482,"journal":{"name":"Indonesian Journal of Forestry Research","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67602323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BIODEGRADATION OF PULP SLUDGE BY Phanerochaete chrysosporium, Penicillium oxalicum and Penicillium citrinum AFTER SIX MONTHS INCUBATION. The rise of pulp and paper production due to market’s demand will increase both main and secondary products of pulp. Secondary products such as pulp sludge have low economic value, but high environmental cost. Therefore, improved technology is needed to raise its value. This study aims to evaluate the ability of Phanerochaete chrysosporium, a combination of Penicillium citrinum and P. oxalicum and a mixture of those three fungal species in decomposing pulp sludge after one and six months incubation. The pulp sludge was collected from pulp company in North Sumatera, Indonesia and it was pre-treated prior to composting. The composting was conducted by inoculating P. chrysosporium, a combination of P. oxalicum and P. citrinum or a mixture of those fungal species with a density of 107 spores/ ml into 15 kg treated sludge. The inoculated sludge was then incubated for one and six months. Analysis was held for the non-inoculated and inoculated sludge regarding pH, cation exchange capacity (CEC) (me/100 g), macronutrients (N, P, K, Ca and Mg) (%), micronutrients (S, Zn) (ppm) and heavy metals (Pb, Cd) (ppm). After one month incubation, P. chrysosporium was leading in enhancing sludge’s macro and micronutrients. After six months incubation, a combination of P. oxalicum and P. citrinum generated higher P, K, CEC and reduced lead content of the sludge. Meanwhile, a mixture of the three fungus species produced the highest N and Mg.

Seed deterioration is the process of deteriorated seed in view of viability that has changed its physiological and nutritional content. This paper studies the effect of seed drying and seed storage to the viability and biochemical content of jelutung (Dyera polyphylla (Miq.) Steenis) seeds. Completely Randomized Design was used for different level of seed drying time, i.e. 0, 24, 48, 72, 96 and 120 hours, and Completely Randomized Factorial Design was used for the combination of seed drying treatments of 0, 24, 48, 72, 96 and 120 hours in different rooms for seed storage (ambient room, air conditioned room, refrigerator) with variables of moisture content, germination percentage and nutritional content. Result shows that seed drying and seed storage treatments pursue the change of seed viability and nutritional content of jelutung seed. The period of time in seed drying and seed storage siginificantly influence the moisture content, germination percentage and nutritional composition (lipid, carbohydrate, protein). The longer time of seed drying will effect significantly to the moisture content and germination percentage, increasing the lipid and protein and decreasing carbohydrate. Jelutung seed that was stored in air conditioned room had better viability compared to ambient room and refrigerator.
