Abstract

ABSTRACT[Acclimation of Siebenrockiella crassicollis in Conservation Area Ex Situ at Bengkulu University].  This study aims to determine the effect of pool water composition on the growth rate of S. crassicollis, which will be conservated in ex situ area of Bengkulu University campus. The turtles initially acclimated in the Sumber Belajar Ilmu Hayati (SBIH) Ruyani Bengkulu. The result of this research shows 50% of well water + 50% of pond water has the highest growth rate of S. crassicolis, but the difference of growth rate in each treatment group does not look different significantly. Thus, the pond water in the ex situ area of Bengkulu University can be recommended for use as an Ex situ Conservation site for S. Crassicollis.  Keywords: S. crassicolis; water pond; student work sheet.(Received August 10 , 2018; Accepted January 9, 2019; Published February 27, 2019) ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh pemberian komposisi air kolam terhadap laju pertumbuhan S.crassicollis, yang akan di konservasi di area ex situ Universitas Bengkulu. Penelitian ini telah dilakukan pada Maret 2017  – April 2017, diaklimasi di Sumber Belajar Ilmu Hayati (SBIH) Ruyani Bengkulu. Hasil penelitian ini adalah pemberian 50% air sumur + 50% air kolam memiliki tingkat laju pertumbuhan S. crassicolis paling tinggi,namun perbedaan rata-rata laju pertumbuhan pada setiap kelompok perlakuan tidak terlihat berbeda signifikan/tidak berbeda nyata. Sehingga, air kolam di area ex situ Universitas Bengkulu dapat direkomendasikan untuk digunakan sebagai lokasi konservasi Ex situ bagi S. crassicolis.Kata kunci : S. crassicolis; air kolam; lembar kerja siswa.

ABSTRACT[Adaptation study of Pipi Putih (Siebenrockiella crassicolli) sexes in conservation pond at University of Bengkulu]. This study aims to compare the adaptability of Pipi Putih turtles (Siebenrockiella crassicollis) of males and females in the conservation pond area of University of Bengkulu (UNIB). Nine S.crassicollis were kept individually in a cage, consisting of three space at three different point. S.crassicollis were fed with kangkung (Ipomea aquatica) as much as 10% of  their body weight. Growth parameters was collected every week for six weeks : (a) weight gain (WG); (b) thick growth of body (TGB); (c) growth of carapace length (GCL), (d) growth of carapace width (GCW); (e) growth of plastron length (GPL)  and (f) plastron width growth (PWG)  The measurement results show: (a) WG: male = 3.50%, female = 2.01% (b) TGB: male = 0.30%, female = -0.05%; (c) GCL: male = 0.16, female = 0.26%, (d) GCW : male = 0.566%, female = 0.47% (e) GPL: male = 0.28%, female = 0, 27% and (f) PWG: male = 1.25%, female = 1.16%. Mean turtle growth percentage of all indicators: male S. crassicollis = 0.01% and 0.69% for female S. crassicollis. We concluded that the adaptability of male S. crassicollis turtles was higher than for female S. crassicollis. Keywords: Conservation; Siebenrockiella crassicollis; turtle; adaptation.(Received August 16, 2018; Accepted January 19, 2019; Published February 26, 2019) ABSTRAKPenelitian ini bertujuan untuk membandingkan kemampuan adaptasi kura-kura pipi putih (Siebenrockiella crassicollis) jantan dan betina di area kolam konservasi Universitas Bengkulu (UNIB). Sembilan ekor S.crassicollis dipelihara secara individu di dalam kerambah. Terdapat tiga kerambah yang diletakkan pada tiga titik berbeda. Kangkung (Ipomea aquatica) merupakan pakan yang diberikan sebanyak 10% dari berat badan. Pengambilan data dilakukan sekali seminggu selama enam pekan.

Hasil pengukuran menunjukkan: (a) PBB: jantan = 3,50 %, betina = 2,01% (b) PTB: jantan =  0,30 %, betina = -0,05% ; (c) PPK : jantan =  0,16, betina = 0,26 %, (d) PLK : jantan = 0,566%, betina = 0,47%  (e) PPP: jantan = 0,28%, betina = 0,27%  dan (f) PLP: jantan = 1,25%, betina = 1,16%. Rata-rata persen pertumbuhan kura-kura dari seluruh indikator: S.crassicollis jantan = 0,01% dan 0,69% untuk S.crassicollis betina. Berdasarkan data yang diperoleh,disimpulkan bahwa tingkat adaptasi kura-kura S.crassicollis jantan lebih tinggi daripada S. crassicollis betina. Kata kunci: Konservasi; Siebenrockiella crassicollis; kura-kura; adaptasi.

Abstract

Seblat Natural Tourism Park is substantial for the well being of Sumatran Elephant which provides suitable habitat in Bengkulu Province. The conversion of former production forest area with Particular Function of Elephant Training Center of Seblat into Convertible Production Forest Area of Seblat as wide as 710 hectares in 2011, and forest enroachment activities resulted in fragmentation of Sumatran Elephant habitat. This fragmentation led to the isolation of Seblat Natural Tourism Park and separation from surrounding forest area, which affects the species abundance of Sumatran Elephant. A study is required to understand the relationship between land cover change and dynamics of species abundance of Sumatran elephant during the period of 2011-2020. The study was conducted in the TWA Seblat with the area of ​​±7,768.36 hectares. Data used in this study were secondary data, particularly inventory data of Sumatran Elephants from the BKSDABengkulu which was obtained using the path transect method from patrol activities as many as ±228 patrols for ±1596 days, and land cover data which was obtained from the Directorate of Forest Resources Inventory and Monitoring, Directorate General of PKTL. Spatial analysis was carried out by performing topology test using ArcGIS 10.4 software and land cover classification based on SNI 7645:2010. Topology test resulted in 1 forest cover class and 6 non-forest cover classes. Statistical analysis carried out was multiple linear regression using the IBM SPSS 26 application by performing the Anova test or F test, and T test. The results of multiple linear regression analysis showed the correlation value (R) 0.753 indicated that there was close relationship between secondary dryland forest (X1) and shrubs (X2) with the dynamics of the species abundance of Sumatran elephant (Y). The contribution of variable X1 and variable X2 in influencing variable Y was56.7%, and 43.3% was influenced by other variables which unincluded in this study. The calculated F value is 3.935 with p value 0.081, andbecause the p value is higher than 0.05, simultaneously secondary dryland forest (X1)  and shrubs (X2) did not influence the dynamics of the species abundance of Sumatran elephant (Y). The calculated T value is 1.776 with value of p=0.126, because value of p is higher than 0.05, partially there is no significant influence between secondary dryland forest (X1) on the dynamics of the species abundance of Sumatran elephant species (Y). Determining the influence of shrubs (X2) on the dynamics of the species abundance of Sumatran elephant (Y) resulted in T value of 2.579 and value of p=0.042, with value of p is lower than 0.05 means that there were significant effect between the two variables.

Abstract

Vegetation establishment is considered as a critical step of mined land rehabilitation. The growing plants do not only prevent soil erosion, but also play important roles in soil ecosystem development. Their litterfall is the main process of transferring organic matter and nutrients from aboveground tree biomass to soil. Thus, its quantification would aid in understanding biomass and nutrient dynamics of the ecosystem. This study was aimed to investigate the litter production and its decomposition rate in a reclaimed mined land using albizia and sesbania, and theireffects on some soil properties. The litter under each stand was biweekly collected for four months. At the same time litter samples were decomposed in mesh nylon bags in soils and the remaining litters were biweekly measured. Soil samples were taken from 0-15 cm depths from each stand for analyses of soil organic C, total N, and cation exchange capacity (CEC). The results demonstrated that total litter production under albizia (10.58 t ha-1 yr-1) was almost twice as much as that under sesbania stands (5.43 t ha-1 yr-1). Albizia litter was dominated by leaf litter (49.26%) and least as understory vegetation (23.31%), whereas sesbania litter was more evenly distributed among litter types. Decomposition rates of all litters were fastest in the initial stage and then gradually decreased. Sesbania leaf litters decomposed fastest, while albizia twigs slowest. Differences in the litter production and decomposition rates of the two species had not sufficiently caused significant effects on organic-C, total N, and CEC of the soilsafter one year of revegetation.Keywords: Albizia (Paraserianthes falcataria), decomposition rates, litter, mined land, Sesbania grandiflora
