Abstract

The utilization of land together between trees and crops is one of the strategies in land rehabilitation program in Indonesia. High pressure from people living surrounding the forest land required the forest managers to invite more participation from the people in managing the forest land. Agroforestry pattern with certain tree species chosen by forest managers together with certain crops preferred by the communities may become the solution for all stakeholders’ interests in a high-pressured forest area. One of the considerations in agroforestry development is economic aspect. This study aims to analyze the financial feasibility of agroforestry pattern auri (Acacia auriculiformis) and peanut, pigeon pea, and corn in Batulanteh forest management unit (FMU) in Sumbawa, West Nusa Tenggara. The feasibility assessment criteria used in this study were Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit Cost Ratio (BCR). The result of this study showed that agroforestry pattern of auri with paddy, peanut, pigeon pea and corn is financially feasible with the NPV, IRR and BCR values are IDR14.607.837.-, 53 % and 1.51 respectively. Keywords: agroforestry, paddy, peanut, pigeon pea, corn, dry land

Abstract

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.Keywords: Brachiaria decumbens, Gliricidia sepium, mining reclamation, nursery, Shorea leprosula

Abstract

Indonesia is estimated to have 14,5 million hectares of karst areas. The characteristic of karst vegetation is specific, one of which is the dominance of small trees. With all of the potency, their vegetation acts as a significant carbon sequester and store it in biomass. This study aims to estimate and discuss biomass estimation in the karst forest within the Nature Recreational Park of Beriat, a protected area in South Sorong, West Papua. A total of 28 plots were made in the forest using the purposive random sampling method. Tree biomass (DBH ≥10 cm) was estimated using five different allometric equations. The results showed that the biomass was estimated at ca. 264 Mg ha-1 (95 % CI: 135-454 Mg ha-1). While small trees (DBH 10 – 30 cm) only contribute 30 % of the total biomass, about 38 % of the biomass is the contribution of large trees (DBH >50 cm), where Pometia pinnata contributes ca. 39 % of the biomass at plot-level. The use of various allometric equations results in different biomass estimates and biases with deviations ranged from -14.78 % to +17.02 % compared to the reference equation. Therefore, the selection of allometric equations used must be considered carefully to reduce uncertainties in biomass estimation.Keywords: allometric model, carbon, climate change, REDD+, specific wood density

Abstract

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.Keywords: deterioration, Falcataria moluccana, invigoration, PEG 6000, UFB, viability, vigor

Abstract

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.Keywords : Bloom’s Taxonomy, knowledge transfer, Whatsapp Group, gender, blended learning, distance learning

Abstract

Medinilla is a tropical forest plant that has potential as an ornamental and medicinal plant. The diversity of medinilla in Bali is poorly studied. This study aims to determine the diversity, distribution and conservation activities of Bali’s medinilla at the Eka Karya Bali Botanical Garden. An observational study, documentation and literature were used in this research. Based on this research, it is known that there are six species of medinilla in Bali such as Medinilla crassifolia (Reinw.ex Blume) Blume, Medinilla alpestris Blume, Medinilla laurifolia (Blume) Blume, Medinilla radicans (Blume) Blume, Medinilla speciosa (Reinw.ex Blume) Blume and Medinilla quadrifolia (BI.) Bakh. F. M. quadrifolia is a new distribution record for Bali. All species were discovered in the districts of Buleleng, Bangli, Gianyar, Jembrana, Karangasem and Tabanan districts. Only four species have been conserved in the Bali Botanical Gardens, according to data from the Eka Karya Bali Botanical Gardens' collection, therefore exploration and collection activities are critical. Conservation activities carried out at Eka Karya Bali Botanical Garden are collecting and data collection, maintaining and propagating species of medinilla.

Abstract

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.Keywords: root cuttings, Kalappia celebica, Rootone-F, Kendari
