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.
