Abstract

There is no data on diameter increment of non-legume plants growing, especially in the reclamation and revegetation areas of the former mining area. This study aimed to calculate the diameter increment, current average increment (CAI), and annual average increment (MAI) of non-legume plants in the reclamation and revegetation area of PT Adaro Indonesia, which operates in Kalimantan Selatan Province, Indonesia. The results of this study can be used by this company to regenerate or embroider vegetation so that vegetation can provide ecological functions in a sustainable manner. In 10 (10 x 20) m2 measuring plots, the circumference of the breast height of woody plants at the pole and tree levels was measured in three measurement periods (December 2016, May 2017, and December 2017). The circumference was converted so that a diameter at breast height was obtained. From this measurement the increment and diameter growth obtained are as follows. Of the six non-legume plant species found and meeting the criteria of poles and trees, only gmelina and jabon could be calculated for increment and diameter growth. The increment and growth of diameter of balik angin, kapok randu, eucalyptus, and alaban were not counted by species because the number of individuals each species was very small, but it was calculated in a combined form with gmelina and jabon so that it become increment and growth of non-legume diameter. The diameter increment over the three measurement periods and the current annual increment (CAI) of gmelina are lower than that of jabon and also non-legume. On the contrary, according to its mean annual increment (MAI), gmelina is higher than jabon and non-legume.Keywords : diameter increment; growth; non-legume; reclamation; coal-mining

Abstract

ABSTRACT. Leaves are the primary feeding source of proboscis monkey (Nasalis larvatus), Borneo endemic primates and protected by Indonesian law. The objective of the study was to inventory the plant species of feed sources and to determine the part of the plant that became the main feed for bekantan in the swamp forest. The number of species occurrences and parts of plants eaten by proboscis was calculated by the IARF method. The density of feeding source plant (pole level) was calculated in 5 (10 m x 10 m) plot and the sapling level in 5 (5 m x 5 m) subplots. The selection ratio of IARF/K and its relative selection ratio was determined. The feeding source plants were galam (Melaleuca leucadendron), mangium (Acacia mangium), and karamunting (Melastoma affine). The leaves were part of the plant that was the main source of feed. Karamunting was a plant that has the greatest selection ratio in the bekantan diet. Keywords: proboscis monkey; leaves; diet; swamp forestABSTRAK.Daun adalah sumber pakan utama bekantan (Nasalis larvatus), primata endemik Borneo dan dilindungi peraturan perundang-undangan Indonesia.Tujuan penelitian adalah menginventarisasi spesies tumbuhan sumber pakan dan menentukan bagian tumbuhan yang menjadi pakan utama bagi bekantan di hutan rawa. Jumlah kejadian spesies dan bagian tumbuhan tersebut dimakan oleh bekantan dihitung dengan metode IARF. Kerapatan tumbuhan pakan tingkat tiang dihitung dalam 5 plot yang luas setiap plotnya (10 x 10) m2 dan tingkat pancang dalam 5 subplot yang luas setiap subplotnya (5 x 5) m2. Rasio seleksi IARF/K serta rasio seleksi relatifnya ditentukan. Bekantan memakan galam (Melaleuca leucadendron), mangium (Acacia mangium), dan karamunting (Melastoma affine). Daun adalah bagian tumbuhan yang menjadi sumber pakan utama. Karamunting merupakan tumbuhan yang rasio seleksinya terbesar dalam pakan bekantan.Kata kunci:bekantan; daun; pakan; hutan rawa

Abstract

The four locations in the PT Adaro Indonesia reclamation area have never been investigated before, so the herb-liana species were also unknown. The purpose of this research was to identify herb-liana species in the reclamation area of the former coal mine and analyze the diversity of species and similarity of the community. Ten plots were made at each location. On a virtual line that extends at a location, one point was randomly determined and used as the initial angle to make a plot (5 m x 5 m). Plot was placed on the left part of the virtual line and one of the plot sides was aligned with the virtual line. At a distance of 20 m from the starting point, the second point was placed, which then become the starting angle for the second plot (5 m x 5 m). Plot was placed on the right part of the virtual line and one of second plot sides was aligned with the virtual line. And so on until 10 plots were formed alternately on the left and right of the virtual line. From these plots, all species of herb-liana were identified and the individual number of each species was accounted. The data was processed so that the Shannon-Wienner diversity index (H ') and the Jacard similarity index (SJ) were obtained. Thirty-four species (15 families) of herb-liana were identified and 1 species was not identified. Species spread differently between certain locations and other locations. Centrosema pubescens dominates 3 locations whose revegetation age is under 5 years, while Asystasia gangetica is only 1 location whose revegetation age is around 5 years. Although the community similarity index values calculated according to the number of species differ from those calculated according to the INP, the results remain the same that the lowest similarity index occurs between Location 1 and Location 3, while the highest is between Location 1 and Location 2.

Abstract

Revegetation with woody plants is a strategic effort to avoid the negative impacts of coal mining and at the same time improve the utilization of ex-mining land. This study aimed to analyze the dominance, diversity, and evenness of woody plant species planted in the reclamation area of PT. Adaro Indonesia. At 4 locations of reclamation area, paths consisting of 10 plots were made. In each plot (20 x 20) m, only 1 plot (10 x 10) m, only 1 plot (5 x 5) m, and only 1 plot (2 x 2) m were successively made. The plot (20 x 20) m was used to record tree level, (10 x 10) m for the pole level, (5 x 5) m for the sapling level, and (2 x 2) m for the seedling level. Dominance was determined by important value index, while diversity and evenness were based on the Shannon index. Fourteen of the 21 woody plant species were intentionally planted and the remaining 7 species grew spontaneously. Of the 14 species, 64.29% were legumes and 35.71% non-legumes. The dominance, diversity and evenness vary according to their level of growth and location. The highest species diversity does not always coincide with the highest species evenness.Keywords: diversity, dominancy, evenness, reclamation area, woody plant

Abstract

Coco Palm-nypa fruit leather (Nyfa fruticans Wurmb) were usually dumped away and not utilized. This research aims to get a Palm fruit flour composition variations as extender on urea adhesive formaldehyde; and physical and mechanical properties of the tested particle board that it generates. Particle board raw materials used 100% of the Coco Palm fruit leather. The adhesive used is urea formaldehyde with a Palm fruit flour composition variations as extender is A = 100% flour nypa, B = 75% of Palm starch and wheat flour, 25% C = 50% flour nypa and 50% wheat flour, D = 25% nypa flour 75% wheat flour , and e. 100% wheat flour. To test the influence of the treatment to physical mechanical properties, the Complete Random Design was applied. The results showed that variations of the extender composition Palm fruit flour to urea formaldehyde adhesive has no significance effect to the water content value, but have significant effect to firmness of broken (MoR) and supple dependability (MoE).
