The purpose of this study is to evaluate the texting, sharing, and mentoring (TSM) method as an innovative method of community empowerment applied in 'Go-Honey' program. This method is mixed offline and online with the use of Whatsapp groups connecting program participants, resource persons, and local mentors. Using the Bloom's Taxonomy approach, this study compares the knowledge level of the 'Go-Honey' program participants implementing TSM with other sitngless beekeeping program participants who use the single-face-to-face (TTM) method as a control. The total participants involved in this study were 20 people, half of whom were female members of 'Go-honey', while the other half were not. Participants were asked questions related to cognitive, affective and psychomotor aspects by direct interviews. Observations were also done on the results of the work performance. The results show that the 'Go-Honey' participants have a higher level of knowledge about stingless beekeeping compared to the control model in these three aspects of knowledge. The results of the Mann Whitney test shows that the cognitive, affective and psychomotor scores are significantly different at 1 % alpha. This method has the potential to be applied after the pandemic ends with the principle of distance learning as long as there is the internet connection and the presence of local mentors.

Kalapi (Kalappia celebica Kosterm.) is endemic in Sulawesi and Endangered species. Plant propagation needs to be done but is constrained by limited seeds. Vegetative propagation of plants can be an alternative method such as using the root cutting technique that has been done previously on other types of species. This study aims to determine the success of vegetative propagation of kalapi (K. celebica), an endangered tree species by root cuttings using Rootone F. as root growth regulator. The research took place from March to June 2019 conducted at the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch, Kendari. This study used a Randomized Block Design (RBD) consisting of 6 treatments of Rootone-F concentration: (a) 0 ppm, (b) 100 ppm, (c) 200 ppm, (d) 300 ppm, (e) 400 ppm and (f) 500 ppm. Each treatment was repeated three times and three units of the plant so that the total experimental unit used was 54 units. The results showed that the provision of Rootone-F could increase the success of the growth of kalapi root cuttings. Rootone-F concentration of 500 ppm gives the best results on the percentage of cuttings, percentage of sprouts, percentage of roots, number of shoots and shoot dry weight. The results showed that kalapi can be propagated by root cuttings.

Utilization of seeds storage results in decreased plant productivity. The increase can be used by treating seeds before planting through the technique of invigoration. This purpose of the study is to assess the effectiveness of invigoration methods using polyethylene glycol (PEG 6000) and ultrafine bubbles (UFB) to improve viability and vigor of sengon seeds (Falcataria moluccana). Seed agieng using 96 % ethanol was carried out to obtain the diversity of seedlot viability as the materials for testing the effectiveness of invigoration treatments. A complete random design was used to test the effectiveness of 5 invigoration treatments, i.e., seed without invigoration treatment, soaking in PEG 6000 -0.8 MPa, soaking in PEG 6000 -1.2 Mpa, soaking in UFB water injected by environmental air, and soaking in UFB water injected by oxygen 99 %, with soaking time is 24 hours for each treatment. Seed agieng resulted three classes of seed viability, i.e. 62 % (initial seed), 83 % (seed agieng for 30 minutes) and 57 % (seed agieng for 60 minutes). In the condition of seed germination before treatment (DBA) 57 % and DBA 62 %, invigoration treatments were significantly affected on seed germination capacity, but not significantly different in DBA 83 %. The soaking treatment of UFB injected by oxigen 99 % was able to improve the germination parameters (germination capacity, germination rate, and vigor index) on the sengon seeds with DBA 57 %. For seeds with DBA 62 %, the soaking treatment in UFB injected by environmental air was provided the best germination capacity, T50, and vigor index. The treatment of UFB injected by oxygen 99 % was more effective to improve the seed with very low viability and vigor (DBA 57 %). In general, improving of seed viability and vigor is more effective by using UFB than PEG 6000.

Social Forestry at Java island or known as IPHPS (Permit for the Utilization of Social Forestry) is part of the agrarian reform of the forestry sector which expected to solve tenurial problems and improve forest governance. The successful implementation of this program could not be separated of the roles of stakeholder involved. This study aimed to 1) identified stakeholders and their roles in the implementation of IPHPS, and 2) analyzed the relationships between stakeholders in the implementation of IPHPS. This research was conducted in the KPH Telawa area of Boyolali Regency, Central Java. This research uses a combination of qualitative and quantitative approaches. Data collection was done by observation, interviews, and literature studies. Data were analyzed based on the research objectives at stakeholder analysis conducted by identifying stakeholders and their roles as well as the relationships between them in the implementation of IPHPS. They involved in the implementation of IPHPS at the Telawa KPH included Perhutani (KPH) Telawa, KTH IPHPS holders (Wonomakmur 1, Wonomakmur 2, Wonolestari 1, and Wonolestari 2) LMDH Participants PHBM, BPKH IX, BPDASHL Pemali Jratun, Field Companion, BDK Kadipaten, Forestry Foundation, NGO Rejo Semut Ireng, PSKL, LHK Office of Central Java Province, BPSKL Jabalnusra, Forest Development Financing Center Public Service Agency (P3H-BLU). Each of the above stakeholders has their respective strengths and interests. This affects the pattern of relations between the stakeholders which in turn will determine the results of the program. A good relationship will support the successful implementation of the program while a bad relationship can hamper the implementation of the program.

Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.

Muara Kaman Sedulang Nature Reserve in East Kalimantan has been damaged due to anthropogenic activities and natural fires. The study aims to explore the floristic composition and soil characteristics in the rehabilitation and protection block to provide plant species information for the restoration activity. Vegetation data were collected in each block with a purposive random sampling method, in a total of 0,36 ha plot sample in rehabilitation block and 0,32 ha in protection block. Soil characteristics samples for physical and chemical measurement were collected in each plot with a composite technique at the soil surface (0 – 30 cm). There are 15 species recorded in rehabilitation block and 30 species in the protection block. The diameter distribution indicated that there are differences in the regeneration process after periods of destruction on each block. The diversity index in the rehabilitation block is low, while in the protection block is low to middle. Mallotus sumatranus is a dominant species in the rehabilitation block, whereas in the protection block is Lagerstroemia speciosa. Lepisanthes alata always presents in all research plots indicated suitability for all type of habitat in the area. Soil type is Endoaquepts Dystrudepts with silt clay loam texture and acid soil.
