Abstract

Teak is a high value wood. The tree trunk has a high economic value because it provides multipurpose wood products. Tree trunks have distinctive biometric characteristics, including teak trunks. The biometric characteristic of a tree species is a problem in the science of forest planning, because the growth of tree trunks is influenced by many factors, including differences in age, location and site. This research will be arranged biometric model of teak tree that grows in Batulanteh Forest Management Unit, beginning with collecting physical data of tree through measurement of tree dimension. This study uses 75 sample trees grown in the Batulanteh Forest Management Unit area. The data used were tested outlier with boxplot method and calculated ratio and correlation. The regression equation was done by using SPSS version 23 program. Different ratios between tree dimensions at different ages were tested using complete randomized design. The results of this study indicate that the growth model of base diameter, diameter at breast height, and total height are characteristic of trees that are highly correlated with other tree biometrics characteristics. So in the management of teak forests Batulanteh Forest Management Unit can make these three characteristics as a reference in looking at the characteristics of other trees. The results also show the ratio Dp / Dbh, Tt / Dbh still fluctuate throughout the age of 10 to 22 years. Keywords : Teak, growth model, inter-dimensional ratio, age

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

Wood preservation aims to enhance durability against environmental degradation and extend its service life. Conventional methods often use synthetic chemicals that negatively impact the environment. This research develops a wood coating and impregnation technique using waste plastic melted in used cooking oil as a penetration medium, offering an eco-friendly and economical solution. The five types of wood tested are bengkirai, glugu, teak, sengon, and melinjo, each with different physical characteristics and porosity. Evaluation was conducted on specific gravity (SG), porosity, expansion, and shrinkage of the wood. The results showed that soaking in the plastic-oil solution increased SG and reduced porosity, particularly in highly porous woods such as sengon and glugu. The rate of plastic impregnation into the wood followed an exponential model with significant variation between wood types. ANOVA analysis confirmed that wood type and soaking duration significantly influenced changes in the physical properties of the wood. The low-carbon development concept is applied by utilizing waste plastic and used cooking oil, reducing carbon emissions from waste incineration, and supporting the circular economy. This method can become a more sustainable, recycled-based wood preservation alternative that supports environmental sustainability

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 has practiced land management in their yard with simple agroforestry as a form of intensification. For the younger generation to understand the practice of agroforestry from an early age, it is necessary to introduce it so that they are motivated to practice it as part of the family income. There are 4 forms of agroforestry, namely trees planted regularly with non-tree plants, there are 2 compositions, namely sengon trees with kimpul, Japanese papaya, sissy. Trees were planted around the land and non-tree trees, such as mahogany, cassava, sweet potato, chili, papaya, ginger, turmeric, galangal, and sissy were planted inside. Mixed trees with 2 trees, namely the composition of mahogany trees, coffee, and mahogany trees, wadang, melinjo, coffee, sissy. Mixed trees next to it are land planted with non-tree 1 composition of mahogany, melinjo, ketapang, johar and the land next to it is banana, papaya, moringa, ginger, chili, spinach, tomato, eggplant, sissy. 2 plants are trying to be more popularized, namely the Sissy plant and Cassava or Cassava. The sissy plant is popularized because it is easy to grow in various conditions, can help treat intestinal and digestive disorders, and is easy to consume like spinach. Cassava or cassava plants for added value, one of which is used to develop Samia silkworm silk.
