Abstract

Ulin (Eusideroxylon zwageri T. & B.), mostly known as the Belian or Iron Wood of Borneo. The spread of ulin can be found in Sumatra and Kalimantan. Nowaday, growth of Ulin is very threatened from extinction due to excessive exploitation by humans and its potential significantly decreased. As a result, natural growth and regeneration of Ulin becomes very slow and limited in its habitat. The sustainability of the results will be achieved if the harvested yields do not exceed the forest growth capability. It is necessary to measure and calculate growth of ulin sprout. This study aims to analyze the growth of ulin sprout in 2014 and 2018 periods. Based on field observation data were 31 samples of ulin sprout studied in May to November 2014 shows the result that none of the ulin sprout suffered dying. Subsequent observations in January 2018 found 29.04% ulin sprout or there are 9 dead of ulin sprout. The results showed that the average growth rate per month (CAI) Ulin sprout ranges from 0.197 cm per month, and at the stake level and 0.300 cm per month at the pole level. While the annual growth (MAI), at the level of stakes of 0.463 cm per year and at the pole level of 1,147 cm per year.Keywords: Ulin sprout; Growth rate

Abstract

ABSTRACT. This study aims to determine the effect of age and time of interception of good rubber latex production. The benefits of this research can be used as a reference or guidance on the effect of age and time of interception on the production of good rubber latex. The method used is Completely Random Design 2x3 Factorial pattern as many as 5 replications with 30 units of experimental unit. Based on the calculation of Various Fingerprint Analysis it is known that the Treatment, Factor A (Age) and Interaction AB are very influential because the F value is bigger than F table 5% and 1%. While Factor B (Time wiretapping) has no significant effect. The results of the calculation of Continuous Difference Test The Smallest Factor A showed that the treatment A1 was very different with the treatment of A2 with different value greater than BNT 5% and 1% ie 2.89> 0.41 and 0.55. Treatment of A1 also differed very significantly with treatment of A3 because of different value more than 5% BNT value and 1% ie 3.61> 0.41 and 0.55. The results of the least significant difference in B-test (BNT) of factor A in Table 8 showed that the treatment of A3 was very different from that of A2. This happened because the different values between the two treatments were greater than the 5% and 1% BNT values of 0.71> 0 , 41 and 0.55 it occurs because the larger the age of the tree, the more rubber sap produced.  Keywords: Tapping, rubber sapABSTRAK.

Abstract

This study aims to calculate the density of stomata, identify the state of stomata and measure the length and width of the stomata of the leaves of the leaves (Ficus variegata Blume) of 3 different seed sources. The research was conducted at the Biology Laboratory of FMIPA ULM Banjarbaru and leaf sampling at Riam Kiwa KHDTK Lobang Baru Village, District. Mataraman, Banjar Regency, South Kalimantan, for 6 months. Data were analyzed using. Data were analyzed using RAL (Completely Randomized Design). The resulting density of stomata is known from South Kalimantan, East Kalimantan and Central Kalimantan seed sources on the underside surface with aninositic type, with a large average density of Central Kalimantan seed sources because of genetic influences. Stomata of life leaves are stomata that have open stomata and closed stomata. Most plants with low CO2 concentrations in the leaves, will make the stomata open. Conversely, high CO2 concentrations in leaves cause the stomata to partially close, with a percentage of seed sources from South Kalimantan at 12% open stomata, East Kalimantan 7.19% open stomata, and Central Kalimantan 13.8% open stomata and there are also closed stomata conditions . The length and width of the stomata with the average leaf source from South Kalimantan with a length of 11.68 µm and a width of 2.78 µm, the source of seeds from East Kalimantan is 11.87 µm long and 2.75 µm wide. And for the length and width of seed sources from Central Kalimantan, which are 12.3 µm and 3.61 µmPenelitian ini bertujuan untuk menghitung kepadatan stomata, identifikasi keadaan stomata dan Ukur panjang dan lebar stomata daun nyawai (Ficus variegata Blume) 3 sumber benih berbeda.

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

The development of herbaceous species according to the time of monitoring at certain sample locations in the PT Adaro Indonesia reclamation area has never been published. The purpose of the study was to compare the diversity of species and the similarity of plant communities growing in certain locations in two consecutive monitoring periods. Four locations that have been revegetated were sampled. At each location, 13 measuring plots (20 m x 20 m) were made and placed systematically. In each of these plots, 2 sub-plots (5 m x 5 m) were placed in 2 angles in opposite positions. From each sub-plot data in the form of herbaceous species names and number of individuals were collected. In one location, the number of plots changed because part of this location turned out to be active mining areas. The number of remaining plots (6 plots) was considered to not affect the results. Data is processed to obtain the density of each species at a certain location (Ki), the relative density of certain species (KRi), the frequency of each species at a certain location (Fi), the relative frequency of certain species (FRi), the importance value index (IVI), the index of species diversity Shannon-Wienner (H'), and the similarity index of the Dice community (IS). The number of species varies at each sample location and shows an increase from first monitoring to second monitoring. The species diversity index also increases. Community similarity index varies, both with calculations based on the presence or absence of species and based on the IVI. Both methods of calculation can be used but it is recommended to use calculations based on IVI.Keywords: Diversity, Monitoring period, Reclamation area, Similarity

Abstract

The plant kamalaka (Phyllanthus emblica) belongs to plants that are fire resistant and are pioneer plants or grow first after forest fires.The plant has function as a medicinal plants. The purpose research was to analyzepresence phytochemical from kamalaka plants based on the differences in growing altitude. This research was carried in three different locations, namely in high altitude of growing location which in Mandiangin, medium altitude of growing location which in Pelaihari and low altitude of growing location which in Landasan Ulin. The method used was by observing and sampling in the field and also identifying the presence phytochemicalthrough lab tests with the Harborne method. The results showed the alkaloid test with Mayer reactor wasn’t detected or negative results, whereas in Wagner and Dragendorff reactors the presence alkaloids were varied which showed positive results ranging from weak positive (+), medium positive (++) and strong positive(+++). The flavonoid testalso were obtained variedpositive results,ranging from weak positive (+), medium positive (++) and strong positive (+++). The characteristicsof growing locations towards the presence alkaloids and flavonoids on each locations were different. This wascaused by such as light intensity, temperature and humidity, tree diameter, altitude locationsand also dominant soil types. In high altitude and in medium altitude of growing location were found that the presence alkaloid compounds were weak and the presence flavonoids were strong, while in low altitude of growing location the presencealkaloid compounds were strong and the presence flavonoid were weak.Keywords: Kamalaka; Alkaloids; Flavonoids and Altitude of Growing Location

Abstract

This study aims to analyze erosion and the level of erosion hazard in the Banyuirang watershed in the Maluka watershed. The method used in this study is the USLE (Universal Soil Loss Equation) method. The results showed that the value obtained from the erosion rate calculation was the highest in the reed with a value of 399.44 tons / ha / year and the lowest value in the plantation with a value of 1.64 tons / ha / year. This shows that the absence of vegetation affects the soil which will be damaged and affects the rate of erosion, especially on steep slopes. The level of erosion hazard varies from very light class (0-SR), mild class I (IR), moderate class 2 (II-S), heavy class 3 (III-B) and very heavy class 4 (IV-SB), class which is very heavy in the reed and bush land. While the level of erosion hazard is very mild located in reed, bush, plantations and secondary forests. The value of erosion hazard level is obtained from the value of erosion rate with erosion hazard class and soil solum depth.Penelitian ini bertujuan untuk menganalisis erosi dan tingkat bahaya erosi di Sub DAS Banyuirang DAS Maluka. Metode yang digunakan dalam penelitian ini adalah metode USLE (Universal Soil Loss Equation). Hasil penelitian menunjukkan bahwa nilai yang diperoleh dari perhitungan laju erosi adalah yang tertinggi ada di lahan alang-alang senilai 399,44 ton / ha / tahun dan nilai terendah di perkebunan dengan nilai 1,64 ton / ha / tahun. Ini menunjukkan bahwa tidak adanya vegetasi berdampak pada tanah yang akan menjadi rusak dan berpengaruh pada laju erosi, terutama pada lereng yang curam. Tingkat bahaya erosi bervariasi dari kelas sangat ringan (0-SR), kelas I ringan (I-R), kelas 2 sedang (II-S), kelas 3 berat (III-B) dan kelas 4 sangat berat (IV-SB), kelas yang sangat berat berada di lahan alang-alang dan semak belukar. Sedangkan tingkat bahaya erosi sangat ringan berada pada lahan alang-alang, semak belukar, perkebunan dan hutan sekunder. Nilai tingkat bahaya erosi diperoleh dari nilai laju erosi dengan kelas bahaya erosi dan kedalaman solum tanah.
