Acclimatization is an attempt to conditioning the plantlets or micro shoots propagated by tissue culture to the environment outside the bottle. This study aims to know the effect of rooting and media acclimatization on the growth of tembesu plantlets in vitro cultures. Two experiments were conducted, these were (1) rooting (in vitro and ex vitro), and (2) type of acclimatization media (100% sand, cocopeat + rice husk, sand + cocopeat , sand, rice husk, and sand + cocopeat + rice husk). Based on the data analysis rooting significantly affects the variables growth (percentage of survival and the number of roots) at the acclimatization stage of tembesu.The percentage of planlets survival in the acclimatization are 80percent for in vitro rooting and 75percent for ex vitro rooting, while on stage after acclimatization percentage of survival are 75 percent for in vitro rooting and 67 percent for ex vitro rooting. In vitro rooting have a better growth than ex vitro rooting, but the plants grown from ex vitro rooting are more resistant to stress. The best acclimatization media for tembesu is 100 percent of sands.

Establishing the Cempaka forestry partnership agroforestry demonstration plot in the Batutegi Forest Management Unit, Lampung Province, should increase small-scale farmers’ participation in planting and enhancing their welfare. They need facilitation and supporting programs to evolve continuously, grow business rapidly, and enable forest sustainability. From previous research, the existing training and the extension supporting programs focus on technological improvements in agroforestry demonstration plots, such as modern nurseries training and incentives awarding. There is minimal understanding of small-scale farmers about the broader market chain beyond their direct market. However, improving the market chain will be sustaining the process of innovation and environmental empowerment. The upscale market chain has an impact on poverty alleviation by enhancing institutional capacity and market linkages. Therefore, integrating a market chain perspective is a crucial priority for planning the demonstration plot capacity program. This research intends to design the procedures for linking small-scale farmers to the market chain using a three-sequence phase usually elaborated in the Participatory Market Chain Approach (PMCA). The data were collected by applying a questionnaire, and then they were described by using a narrative-based qualitative method. The emerging results from this study are the policy implications for improving the performance of the market chain in a standard timeline, namely the assessment phase, the innovation phase, and the action phase. Ideally, policy leaders should pay attention to the assessment phase that identifies interactions among market chain actors. The innovation phase develops on-site learning exercises and tests shared innovation. The action phase promotes in topic meetings and action groups.

Biofuel production as an alternative energy source has been promoted and spread worldwide, but there is actual potential. Malapari (Pongamia pinnata) is a forestry-based biofuel. This paper aims to determine community perception and attitude towards malapari as a biofuel. The research was conducted in August - October 2018 in Patutrejo Village, Grabag District, Purworejo Regency, Central Java. This research was conducted using a survey method. Determination of respondents used a purposive sampling method. Respondents consisted of 38 people. The result showed respondents had poor to feeble perceptions and attitudes towards malapari. It is presumably because public knowledge of the use of malapari as a biofuel is low due to lack of socialization from related parties. There is no evidence of the utilization/processing of malapari seeds as a biofuel.

The existence of the muna teak (Tectona grandis L.), is currently threatened with extinction, so a muna teak replanting program is needed. Micropropagation techniques can be one solution for the supply of high quality seedlings. The purpose of this study was to obtain the optimum sterilization technique to get the sterilize explants of muna teak and to get the suitable media for in vitro multiplication. The study was conducted in a tissue culture laboratory of the Forest Tree Seed Technology Research and Development Centre in Bogor. This study consisted of two stages and the experimental design used was a completely randomized design. The first phase of the study was the treatment of sterilization techniques consisted of soaking explants in various concentration of clorox solution and the second stage of the study was the treatment of multiplication media. The results showed that the proper sterilization technique to obtain sterilize explants of muna teak seedlings was immersed in 20% chlorox solution for 10 minutes, then immersed in 15% of chlorox for 15 minutes. The best medium for the induction stage and multiplication of Muna teak buds which are modified media plus Benzyl Amino Purine (BAP) hormone as much as 0.1 mg.l -1

Sengon known as forest product with high market demand. Tissue culture is one multiplication method to get seeds in large quantities. One factors that support the success of reproduction is the health of the plant material. The purpose of the study is to determine the influence of pre-sterilization treatments towards the successful initiation of sengon organogenesis. The research method was done by spraying the seedlings with Pyraclostrobin 50 g.kg-1 + Metiram 550 g.kg-1 of 2,500 ppm every week for 3 months. Each explant was grown on MS medium.The observation was carried out done every 1 week for 12 weeks, including the amount of contamination (bacteria, fungi), browning and the appearance of buds, roots and callus. Data were analyzed by t-test. The next stage is multiplication by using treatments of 24D 0.1 mM, 24D 0.5 mM, BAP 0.5 mM, BAP 2 mM, K 0.1 mM, K 0.5 mM, TDZ 0.1 mM, TDZ 0, 5 mM, and control. Completely randomized design was used and analyzed by using one way ANOVA, and tested with Duncan for the differences at 0,05 significant level. The results showed that pra-sterilization treatment was capable of supporting the successful initiation of sengon shoots characterized by low levels of contamination, increased number of callus and number of sengon shoots explants. Kinetin 0.01 mM in the multiplication media of sengon shoots was able to increase the number of adventitious shoots.
