Abstract

Most of the people who own community forests in Gunung Kidul, in their management, have formed Forest Farmers Groups (KTH), which aim to improve living standards and the economy through businesses in the forestry sector. Member participation in activities carried out by KTH is one of the approaches for KTH in generating ideas/ideas/programs in the context of solving problems for its members, increasing social awareness, improving human resources, and regeneration. This research aims to determine the extent of participation of KTH members in Kedungpoh village, Nglipar Gunung Kidul District in their activities and determine the correlation with their sociodemographic conditions. The method used in this research is a survey method which is analyzed using correlation analysis and crosstab. This research shows that the level of participation of members of the Forest Farmers Group in their activities in planning is 78.30%, implementation is 89.88% and evaluation is 66.39%, while the socio-demographic condition of the members of the Farmers group which has a correlation in participation in activities organized by the Forest Farmers Group is age. and years of farming, which is closely related to members' motivation in participating in activities, namely to increase knowledge, receive agricultural assistance, gain experience, develop personal potential, increase enthusiasm and obtain agricultural training. This research also shows that there is a relationship/correlation between activity stages, namely between the stages of activity planning, activity implementation and activity evaluation.

Abstract

Macroinvertebrates from the EPT group (Ephemeroptera, Plecoptera, and Trichoptera) are known as sensitive bioindicators of aquatic pollution. This study aims to assess the ecological health of the Opak River in the Special Region of Yogyakarta using biomonitoring based on the presence and diversity of EPT taxa. Sampling was conducted at three observation sites—upstream (Leses Village), midstream (Bawuran), and downstream (Sriharjo)—using kick sampling and jabbing methods. The results showed that EPT were only found at the upstream station, represented by two families (Psychomyiidae and Polycentropodidae), while no EPT were detected at the midstream and downstream stations. Based on the Biotilik index and supporting parameters, the water quality in the upstream area was classified as moderately polluted, whereas the midstream and downstream areas were classified as heavily polluted. The decline in river quality correlates strongly with anthropogenic activities such as agriculture, livestock farming, industrial waste, and household sewage discharge. This study emphasizes the importance of river conservation and management through biological indicators to support the sustainability of freshwater ecosystems.

Abstract

One of the problem in using wood species with low natural durability such as   Anthocephalus cadamba is their susceptibility to various wood-destroying organisms, including wood-staining fungi (blue stain). These fungi tend to attack wood with high moisture content, causing discoloration into bluish, brownish, or blackish tones, which in turn reduces the quality and usability of the wood. Wood preservation using extracts from sawdust of naturally durable wood species such as Eusideroxylon zwageri and Dalbergia latifolia can serve as an alternative to chemical preservatives. The purpose of this study was to know the effect of wood extract type and preservative solution formulation on the absorption, retention, and the intensity of blue stain fungal attack on A. cadamba wood. The wood was treated using E. zwageri  and  D. latifolia  sawdust extracts at   10%, 20%, and 30% solution formula, and then exposed to blue stain fungi for 1.5 months. The results of the study showed that the two type of wood extracts were effective as wood preservatives against blue stain fungal attacks on A. cadamba wood. The preservative formulation had a significant effect on absorption, retention, and intensity of fungal attack. The highest preservative retention and the lowest intensity of fungal attack were found at the 30% solution formula, with values of 21.020 Kg/m³ for retention and 1.04% for fungal attack intensity.

Abstract

Plantation quality assessment is very important for evaluating the success of seedlings in growth, especially in industrial plantations. This study aims to determine the most effective and accurate plot sampling method for assessing the survival and stocking of Acacia crassicarpa. Two types of sampling plots were compared, namely line plots and circular plots, by recording the number of alive and dead plants, as well as measuring the time required for each plot. Statistical analysis was conducted to present statistical descriptions (mean, standard deviation, standard error, and sampling error). Additionally, an independent samples t-test was performed between plot types, preceded by a Levene's test for homogeneity of variances. The results showed that plant density assessments differed between line plots and circular plots. For survival, there was no significant difference between the two plot types. In terms of time efficiency, line plots were superior because the sample area consisted of straight lines, while circular plots took longer to implement, especially during moving from one to another plot. Therefore, the choice of method depends on the assessment objective. For assessing the success of the plants under study, the strip plot is more stable for assessing plant density

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.

Abstract

The Widodomartani community cultivates some of their land for forest plants, generally sengon  is liked community because fast growing species and harvested quickly. Generally, the planting used is seedling, for efisiensi budgeting tried with coppice sistem. This research aims to determine the growth of second rotation at the age 1-years old sengon with coppice sistem. The growth data taken is sum coppice at every sengon, and height, diameter for each coppice at individual sengon. The results research showed that coppice after first rotation used seedling at the age 1-years old sengon there is a tendency that the larger the diameter of the stump or stump, the more shoots there are. The growth of sengon (Falcataria moluccana) plants in the second rotation, aged 1 year, originating from coppice shoots (coppice system) from a 5 years old stand, with an average height of 5.193–7.596 m and an average diameter of 3.396–5.656 cm per shoot, showed better results than sengon growth in the first rotation. The disturbance found was tumor rust caused by Uromycladium tepperianum.
