Abstract

Biosekuestrasi atau penyerapan karbondioksida oleh vegetasi merupakan salah satu pengelolaan cadangan karbon yang penting untuk digarisbawahi dalam setiap pertemuan internasional, tetapi ketersediaan data tersebut masih kurang lengkap dan tersebar. Data cadangan karbon dari vegetasi dan tanah gambut sangat penting untuk mengurangi variasi pendugaan stok karbon di hutan gambut. Tujuan penelitian ini adalah untuk memformulasikan persamaan alometrik dalam pendugaan biomassa pohon di hutan gambut primer dan bekas kebakaran serta untuk menganalisis cadangan karbon vegetasi di hutan gambut primer dan bekas kebakaran. Penelitian dilakukan di hutan gambut primer (HGP), hutan gambut bekas terbakar berulang tiap tahun (HG1), hutan gambut bekas terbakar setelah tiga tahun (HG3), dan hutan gambut bekas terbakar setelah delapan tahun (HG8). Klaster plot dibuat di setiap hutan gambut primer dan bekas kebakaran yang mewakili periode kondisi setelah kebakaran dan hutan gambut tidak terganggu. Setiap klaster terdiri dari empat subplot lingkaran (jari-jari 7,32 m) dan empat annular lingkaran (jari-jari 17,95 m). Jumlah total adalah 16 subplot lingkaran serta 16 annular lingkaran. Data cadangan biomassa karbon dikumpulkan dalam plot-plot tersebut.  Hasil penelitian menunjukkan bahwa untuk menduga biomassa total pada keseluruhan klaster, maka persamaan alometrik yang paling tepat adalah Y = 0,061 (DBHxρxT)1,464. Persamaan alometrik umum keseluruhan klaster tersebut digunakan untuk pengguna di lapangan dalam menghitung cadangan biomassa karbon tegakan.  Persamaan umum ini dapat digunakan karena semua klaster penelitian memiliki wilayah zona iklim curah hujan sebesar 2.621-3.339 mm/tahun yang termasuk dalam zona iklim moist 1.500-4.000 mm/tahun (Brown et al., 1989).  Masing-masing persamaan alometrik tiap klaster yang diperoleh dari hasil penelitian ini digunakan untuk menduga cadangan biomassa karbon tegakan tiap klaster.  Persamaan alometrik terpilih penduga biomassa total untuk hutan gambut primer adalah Y = 0,040 (DBHxρxT)1,524; untuk hutan gambut bekas terbakar berulang tiap tahun adalah Y = 0,098 (DBH)2,350; untuk hutan gambut bekas terbakar setelah tiga tahun adalah Y = 0,084 (DBHxρxT)1,376; untuk hutan gambut bekas terbakar setelah delapan tahun adalah  Y = 0,024 (DBHxρxT)1,667. Cadangan karbon total yang merupakan jumlah dari tumbuhan bawah, semai, pancang, tiang, dan pohon adalah sebesar 73,08 tonC/ha di HGP; 4,93 tonC/ha di HG1; 13,64 tonC/ha di HG3; dan 26,13 tonC/ha di HG8.

Abstract

Mount Rinjani National Park (MNRP) in the West Nusa Tenggara Province, popular as one of ectourism destinations for both international and domestic tourist. The number of tourist increases every year. However, MRNP was facing various problems including forest destruction which then becomes critical degraded lands, watersheds damaged, decreased of river water, garbage found at every ecotourism area due to lack of awareness and concern on the ecotourism resources value. This study aimed to analyze the willingness to pay (WTP) for MRNP ecotourism and determine the factors that affect it. The method was using contingent valuation method (CVM) to determine the value of ecotourism WTP and regression to determine the influenced factors to the value of WTP. The results showed that the mean of WTP was US $54.13 for international tourist, with MRNP ecotourism economic value and estimated revenue from entrance ticket of US $1,208,790/ year or Rp 14.50 billion/ year. While the mean of WTP for domestic tourist was Rp 40,650 with MRNP ecotourism economic value and estimated revenue from entrance fee were Rp 883,202,550. Factors that influenced the WTP both international and domestic tourists were education, income, family members, active in environmental organizations and knowledge on ecotourism.

Abstract

Ecotourism in Mount Rinjani National Park (MRNP) faces various environmental problems that lead to conflicts. Therefore, an analysis of sustainability status of MRNP ecotourism management is carried out. The method for evaluating the sustainability status of MRNP ecotourism management is MDS (multi-dimensional scaling) with Rap-fish or Rapid Appraisal Index modified to Rap-ecotourism. The index value to determine the sustainability status is obtained from scoring value of dimensions’ attributes studied. Then, a leverage analysis is performed to observe the leverage's attributes and fall into the sensitive category as a driver for determining the sustainability of a dimension. These attributes need to be intervened by developing policies so that the index value goes into a sustainable level. The results show that the economic dimension (58.49%) is in quite sustainable level, while the ecological dimension (35.94%), social dimension (45.81%), ecotourism service dimension (39.58%), and technology and infrastructure dimension (35.29%) are in less sustainable stage. While institutional and policy dimension (23.76%) is in not sustainable status. On institutional and policy dimensions, the main lever attributes are (1) local institutions (5.53%), (2) partnerships and collaborations (5.53%), and (3) MRNP ecotourism management and control regulations (5.36%).

Abstract

Tenebrio molitor L is one of the alternative feed ingredients because it is rich in nutrients, namely protein, vitamins, minerals (calcium), energy, and fat. Tenebrio molitor L also contains 33.64±0.22% omega-3, so it is hoped that the eggs produced contain omega-3. In this study 300 Lohman Brown laying hens of 20-week-old were used. Completely randomized design (CRD) was applied in this study with 3 treatments and 10 replications, each replication contained 10 laying hens. Treatments were: P0= Feed containing 5% MBM, P1= Feed containing 2.5% MBM + 2.5% Tenebrio molitor L, and P2= Feed containing 5% Tenebrio molitor L. This research was conducted for 6 months. The variables observed were egg production, egg weight, egg shape index, shell weight, shell thickness, Haugh unit, yolk index, and omega-3. Treatment had no influence on egg physical quality but had a significant influence on egg weight. Treatment P0 prodeced the lowest egg weight that was 59.02±0.53 g. Treatment P2 had higher omega-3 contents than P0 and P1 that was 88±0.12 mg 100 g-1. It was concluded that Tenebrio molitor L could replace MBM up to 5% in laying hens feed, improve eggs quality, and omega-3 content in eggs.

Abstract

Land  cover  changes will affect the ecological condition of  the watershed.  Currently, the  conversion of  natural forests into agricultural land has been one of  the main  causes of  deforestation  in  Indonesia. The  changes  could  give impact to  erosion,  increased  run off  and  sedimentation,  loss of  biodiversity,  change of micro  climate,  the release of carbon and Green House Gas (GHG) into the air, etc. This problem has been going on in Watershed Ciliwung.  Forest area, as sources of carbon deposits and carbon absorbents, has limited area along with increasing extents of build up areas. Therefore, it’s estimated the ecological changes will be extended, then will affect the amount of carbon  stocks in Watershed Ciliwung. The objectives of research are  to determine  land cover changes during  the  last twenty years,  to analyze actual carbon stocks in watershed Ciliwung, and to analyze the effect of land cover changes in over twenty years of greenhouse gases, especially CO2. This research used three samples plot on each of the existing land cover. Biomass approach was used in order to estimate carbon stock. Changes in carbon stocks were calculated by using interpolation based on  the actual  carbon  stocks  in 2011. The  research  results  showed  that build up areas was  increased  153,36% during twenty years. The highest potencial carbon stocks was  found in pines forests, which is 144,99 tons/ha. Over the last twenty years, carbon stocks in watershed Ciliwung is declined 42.329,75 tons carbon or 155.350,182 tons CO2e.

Abstract

Water demand should be balance with water availability. The population of Bogor City was increased every year, so that water demand become increased. Currently, Government of Bogor City only utilizes the Cisadane river as a source for drinking water, but Bogor City has 2 rivers there are Cisadane river and Ciliwung river. So, Ciliwung river can be solution for this problem. Water discharge and rainfall influence water availability. Distribution log pearson type 3 used to predict the water discharge and rainfall and linier regression analyzed the relationship between water discharge (dependent variable) with rainfall as X1 and water level as X2 (independent variable). The result of distribution log pearson type 3 every return period 2, 5, 10, 25, dan 50 years is water discharge and rainfall were increased. Average increase of water discharge every return period is 1.6 m3/s and average increase of rainfall every return period is 251 mm. Partially, water discharge influenced by water level 97.7% and 2% by rainfall. But, = 0.000 < = 0.05. it is mean rainfall and water level cannot be ignored because it can influence water discharge with regression model = -3.01 + 0.000 X1 + 0.202 X2.
