Abstract

Thinning is one of silvicultural management actions in maintaining and increasing growth and quality of standing stands. This study aims to determine growth response of selected teak clone to several intensities of thinning and intercropping. The method was a factorial completely randomized block design (RCBD) with thinning intensity (4 levels): 0% (control = A1), 25% (A2), 50% (A3) and 75% (A4) as the main plot, while intercropping (2 levels), as the sub plot. The results showed that the Current Annual Increment (CAI) of diameter at breast height (CAI DBH), volume/tree (CAI vol/tree) and volume/hectare (CAI vol/ha) of stands gave a significant positive response to thinning intensity treatment. CAI DBH one year after thinning were 0.79 cm, 1.47 cm, and 2.46 cm; increased by 32%, 145% and 310% at the thinning intensity of 25%, 50% and 75% when they compared with the control (0.59 cm). CAI vol/ha of stand in the first year, namely 11.88 m/ha, 14.04m3/ha, and 16.78 m3/ha or with an increase of 9%, 29% and 54% respectively at an intensity of 25 %, 50% and 75% compared to the control.

Abstract

Teak clone number 97 and 110 have been developed by Perum Perhutani and Fakultas Kehutanan Universitas Gadjah Mada year 2004 / 2005. The aim of this research is to know survival rate, stand density, growth; and relation between level of stand density within growth of teak clone number 97 and 110 at the age of 10 years in BKPH Begal KPH Ngawi, Perum Perhutani East Java. Research is committed through making 32 checks measure permanent of the size 60 m x 50 m. The result of research indicated that after age 10 years, teak clone number 97 and 110 have survival rate 69,77 % or with stand density 581 trees/ha. There are 252 trees/ha experience death in range. Growth data indicate that there is relationship of negativity between growth of diameter with stand density, that is with value of correlation (r) = ˗ 0.6598. The relationship is explainable through y's regression equation= ˗0.008x+25.46, with value R² = 0.435.

Abstract

This study aims to determine the effect of seed soaking temperature in room temperature water (240C) and (600C), determine the effect of soaking time at the level of 0 hours (control), 6 hours, 12 hours, 18 hours, determine the effect of the type of soaking water, namely Kahayan River water, Peat water, PDAM water, Aquades water, and determine the effect of all the best interactions on the germination of Trembesi tree seeds. The research method used a complete randomized design (CRD) Factorial A x B x C, each factor A = 2 levels namely A1 (240C) and A2 (600C), factor B = 4 levels namely B1 (0 hours) without control, B2 (6 hours), B3 (12 hours), B4 (18 hours), factor C = 4 levels namely C1 (khayan river water), C2 (peat water), C3 (PDAM water), C4 (distilled water) with 3 replicates. The results showed that water with a temperature of 600C for a soaking time of 6 hours and soaking in peat water produced the best germination of Trembesi tree seeds because the temperature can help the process of breaking down food reserves so that enzymes work well and soaking for 6 hours can absorb water so that the softening of the seed coat and the development of the seed coat and the soaking water used has a high content of organic matter and carbon substances that are acidic with a pH of 3.8 which can soften the seed coat so as to accelerate the germination process. The interaction factor of temperature, soaking time, and soaking water (AxBxC) at a temperature of (600C) for 6 hours using peat water produces the best germination of Trembesi tree seeds.

Abstract

This study aims to describe the techniques of rattan processing and the production process of rattan handicrafts, analyze the income of rattan artisans, and identify the challenges faced by artisans in Tumbang Habangoi Village. The research employed a saturated sampling method (census) and collected data through observation, interviews, and questionnaires. Data were analyzed using revenue and income analysis, as well as qualitative descriptive methods. The findings indicate that the rattan processing and crafting stages typically involve soaking the rattan, drying the stems, cleaning the stems (locally known as maruntih and mangalingking), processing, cutting, and splitting the rattan stems and strands, skinning, thinning, and weaving. The resulting woven products include mats, bags, lanjung (traditional backpacks), baskets, tangok, embung, tampi, pot coasters, and bubu (fish traps). The average annual production cost is IDR 449,875, with an average annual revenue of IDR 1,522,500 and an average annual income of IDR 1,246,750. The primary challenges identified include limited market access and a lack of product innovation, which hinder the development of rattan handicrafts in the community.
