Abstract

The parameters of color change zone and color darkness level are affected by the treatment of screw deepthness. The parameter of fragrant level is also affected by treatment of screw deepthness. The treatment of screw deepthness (1,54 cm) is the best, then screw deepthness 1,27 cm and screw deepthness 1 cm respectively. The parameter of terpenoid content is significantly affected by interaction of treatment screw deepthness and giving etepon. Treatment combination of etepon concentration 1,.5% and screw deepthness 1 cm is the best to give terpenoid content value (1,266). Keywords : Mechanical treatment, Etilen, Terpenoid

Abstract

Agroforestry, the practice of growing trees and crops in interacting combinations, has a pivotal role to reduce the CO2 concentration in the atmosphere, and it subsequently sequesters the carbon in part of stems, branches, roots, and crowns of the trees composing their vegetation communities. The objective of the research is to know the carbon sequestration in the three agroforestry practices; those are multilayer tree garden, taungya, and home garden. The research was carried out from April 2017 to March 2018 at Sragen and Karanganyar regency central Java Province. Plot method, with the plot size of 20m x20m for trees, 10m x10 m for pole, and 5m x5m for sapling, was used in the sampling. The carbon sequestration was measured by Chave's allometric equation. The carbon sequestration of above ground the trees planted at taungya was 265.18 kg C ha-1 y-1, in home garden was 236.29 kg C ha-1 y-1, and in multi layer tree garden was 290.14 kg C ha-1 y-1. Seasonal fluctuation of the higest carbon sequestration in home garden occurs on October-December; in multilayer tree garden occurs on January-March; and in taungya occurs on July-September. Key words: Agroforestry practices, G.versteegii, seasonal fluctuation, Carbon sequestration

Abstract

Agarwood is one of non wood forest products that has very good prospect to be developed. Right now, the market demand of agarwood products is become more increasing, so study of artificial agarwood  production  is necessary to be expanded. At process of agarwood plant inoculation, the suitable inoculant with proper volume and distance between inoculation holes, will effect against inoculation result. Purpose of this study were to know effect of inoculant volume and distance between inoculation holes against response of Aquilaria malaccencis after three month  inoculated. Results of the research showed that percentage of inoculation success at A. malaccensis that inoculated with 2,5 ; 5 and 7,5 ml inoculant volume and distance between inoculation holes 5 x 5 and 10 x 10 cm were 100%, its meaned all inoculated plant were infected with fungus. Inoculant volume did not give  significant effect against length of  fungal infection, but there was tendency that 7,5 ml inoculant volume resulted higher length of fungal infection than 2,5 ml  and 5 ml volume. The distance  between inoculation holes 5 x 5 cm resulted higher length of  fungal infection than 10 x 10 cm, i.e 7.82 cm  and 1.89 cm. Fragrance level of Aquilaria malaccensis inoculation result after 3 months inoculated was classified in the fragrant criteria.  Keywords : distance between inoculation holes; inoculant volume; test response

Abstract

ABSTRACT The concept of sustainable tourism which prioritizes environmental, natural and cultural preservation is known as "ecotourism". Mangroves are a unique ecosystem that has a lot of diversity and beauty. The presence of mangrove ecotourism in the community can have a positive impact and play an important role in ecosystem life. Therefore, community perception, motivation and participation are important factors that determine the existence of ecotourism in an area. Positive perceptions can encourage active community participation in conservation activities, environmental education and ecotourism development. On the other hand, negative perceptions or lack of understanding can become obstacles in environmental conservation efforts. This research was carried out for 3 months in the Kano Maritim Baros Mangrove Ecotourism area, Bantul Regency, Special Region of Yogyakarta. This research aims to see and analyze the perceptions, motivations and participation of communities involved in mangrove ecotourism in Kano Maritim Baros. To process respondent data, this research uses a Likert scale and correlation analysis. The number of respondents in this study was fifty. The results of this study show that the three variables tested for correlation do not have a significant correlation with each other. Apart from that, the perception, motivation and involvement of the community towards the existence of the Kano Maritim Baros mangrove ecotourism is categorized as "Good".

Abstract

The people of Widodomartani mostly have agricultural land that is managed independently. One of the agricultural land management practices carried out is sengon and cassava agroforestry. Cassava in addition to being taken from the tubers and leaves for vegetables can also be used for the cultivation of samia ricini silkworms. Cassava is usually planted on the sengon path on the guludan path. The planting distance of sengon is 2m x 2m while the distance between yams is 2m x 0.7 m or between sengon there are 3 cassava. This study aims to determine life cycle of Samia ricini silkworms, the production of cassava leaves and their potential for the cultivation of Samia ricini silkworms. The method used was to take samples of cassava plants to calculate the number of stalks, calculate the weight of the leaves and convert the feed needs of Samia ricini caterpillars and to known life cycle of Samia ricini silkworms. The results of the study obtained for life cycle of Samia ricini silkworms 53-61 days (eeg fases 7 days, 21-30 days caterpillars/larva, 17 days cocoon/pupae, and 8 days imago/silkworms) and an average leaf production per cassava plant of 123,466 leaf stalks. The number of plants per ha is around 7,142,857 plants. The potential production of the number of thigh leaves is 881,899,982 stalks. The average weight of 1 petiole is 4.06 grams (average 2.786 grams without stalk). The feed requirement of 1 large caterpillar is 15.3097 petioles / 62.157 gr (42.6528 gr without stalk). One hectare of sengon and cassava agroforestry land can support the cultivation of 57,603,348 samia ricini caterpillars. The average weight of one cocoon is 2.10 grams and silk (cocoon not pupae) 0.28571 gr (13,6%). One ha of land can support the production of silk cocoon as much as 120,967,030 gr or 120,967 kg.

Abstract

Agarwood agroforestry represents a land management system that combines agarwood-producing plants with food crops as a strategy for diversifying community food security sources. This study aimed to analyze the composition and species diversity of agarwood agroforestry components and evaluate their contribution to food security through food crop diversification. The research was conducted in Parangtritis Village, Kretek Sub-district, and Sawo Hamlet, Banguntapan Sub-district, Bantul Regency, Special Region of Yogyakarta, using systematic sampling method with 10 plots sized 20×20 m² (7 plots in Parangtritis, 3 plots in Sawo). Parameters measured included species composition, vegetation structure, and plant utilization for food security. Parameters measured in this study were: species, number, and plant benefits. Plant species identification used Steenis (1988) reference book. Species diversity index employed Shannon's index formula. The research findings revealed 24 tree species within 22 genera and 18 families with a total of 296 individuals. Of this number, 17 species (70.8%) contributed directly to food security, comprising: 15 fruit-producing species, 1 vegetable species, 1 oil-producing species, and 4 medicinal plant species. Shannon diversity indices in Parangtritis and Sawo were 1.46 and 1.87 respectively (moderate category), with evenness indices of 0.59 and 0.65 (moderate category). Species richness in Sawo (R=4.12) was higher compared to Parangtritis (R=2.02). The agarwood-based homegarden agroforestry system proved capable of providing sustainable food diversification with varied harvest seasons ensuring year-round food availability, thus having potential as a community-based food security model.
