Pengaruh koreksi bias dan metode ensemble pada data curah hujan dari empat model luaran Regional Climate Model (RCM) CORDEX-SEA di Sumatera
Get PDFDrought is a natural disaster that occurs slowly and lasts longer until the wet season occurred. Drought occurred in expected time, so that preparations and preparedness can be made in dealing with drought disasters. Therefore, we need an overview of future drought events (or projections).In this study, Standardized Precipitation Index (SPI) was used as drought index. The occurrence of drought is closely related to weather factors and occurs repeatedly. Time-series weather data is needed to know the time-series weather conditions. Problems with data that often occur can be overcome by using numerical climate modeling which is currently widely used. Regional Climate Model (RCM) is a climate model that can be used to build long-term climate data, both time-series and projection data. The results showed RCM model data required bias correction in order to reduce bias in the CORDEX RCM model data. RCM rainfall models before correction were still biased. Thus, bias correction is needed to reduce bias in models data. Time series obtained from SPI baseline data for 2000-2005 in Lampung and West Sumatra provinces showed SPI value which smaller than the projection SPI value in 2021-2030. While SPI time series with RCP 4.5 and 8.5 scenarios showed different results. SPI with RCP 8.5 scenario have more negative value so that drought occurred more often than RCP 4.5. The negative SPI index that often occured in RCP 8.5 scenario appeared to be in RCM IPSL and MPI models year 2025-2030
Review: The ethnotaxonomy and bioecology of pasak bumi (Eurycoma longifolia Jack.)
Get PDFEurycoma longifolia (EL) is a species that have economical benefit as medicinal ingredients for human health. This species grows in tropical forest areas with high rainfall. Research on the ecology of EL has been done a lot, but research related to ethnotaxonomic, bioecology that includes morphology, ecology, and the association of EL with other plants hasn’t been done much. This study aim to analyze the bioecology of EL plant. The method is literature study, which is looking for literature on the results of research that has been carried out related to EL. The results showed that EL has long been known by the communities of Indonesia and other countries in Southeast Asia with several local names. This plant is also associated with other plants around where it grows, one of which is kempas (Koompassia malaccensis). Based on the results of literature review, research on natural regeneration of EL hasn’t been done much. Therefore, there is a need for research related to the natural regeneration of EL.

Hasil menunjukkan bahwa dispersi dioksin dimodelkan solusi persamaan adveksi-difusi non Gaussian dengan memperhitungkan kecepatan jatuh dan diposisi. Untuk MWPP dengan kapasitas 80 ton per hari menghasilkan konsentrasi dioksin 0.04 pg TEQ/Nm3 di wilayah masyarakat sekitar 200m dari cerobong. Paparan inhalasi yang diterima adalah 5.28 pg 1-TEQ/(kg-hari) pada orang dewasa dan 6.95 pg 1-TEQ/(kg-hari) pada anak-anak. Strategi yang dapat dilakukan supaya sesuai standar WHO sebesar 4pg 1-TEQ/(kg-hari) dilakukan dengan menaikkan kemampuan APC untuk mereduksi emisi 25%. Tetapi perhitungan emisi dengan proses pembakaran menunjukkan bahwa konsentrasi yang dihasilkan oleh MWPP masih memenuhi batas ambang yang disyaratkan WHO .We assess of environemental effect of the dioxin dispersion from municipal waste power plant (MWPP) covering, characteristic of the dispersion and health risk affected communities in Indonesia. The dispersion studies through modeling which is done with the following steps 1 ) estimate dioxin emissions from incinerator processing, 2 ) design the dioxin dispersion by literature review, 3 ) calculate health risk of communities based on the dispersion modeling. The results show that the dispersion of dioxin is represented in the form of a non-Gaussian solution of the advection-diffusion equation with taking into account the settling and deposition velocity. In the case of MWPP with capacity, 80 tonnes per day produce a concentration of 0.04 pg TEQ/Nm3 in residential areas which are located 200m from chimney. Inhalation exposure resulting is 5.28 pg 1-TEQ/( kg-day ) to adults and 6.95 pg 1-TEQ/( kg-day ) to children. The strategy took to adjust by WHO environmental quality standard 4 pg 1-TEQ /( kg-day ), we increase the reduction of APC 25%. The calculation of emissions based on combustion processes shows that the dioxin concentration of MWPP is still below the threshold required by WHO

Power Asymmetry : The Paradox of Collaborative Management in Management of Tempe Lake, South Sulawesi
Get PDFTulisan ini bertujuan untuk menjelaskan asimetri kekuasaan sebagai paradoks dalam pengelolaan kolaborasi (co-management) sumber daya alam di Danau Tempe Sulawesi Selatan. Penelitian ini menggunakan metode penelitian kualitatif dengan pendekatan studi kasus eksplanatif. Pengumpulan data menggunakan pengamatan terlibat dan wawancara mendalam. Informan kunci yang berasal dari unsur Pemerintah Daerah, nelayan besar, nelayan tradisional, petani, pedagang, dan LSM. Hasil penelitian menyimpulkan bahwa pengelolaan Danau Tempe diwarnai oleh asimetri atau ketimpangan kekuasaan antar aktor. Aktor Nelayan besar bersama Pemerintah Daerah menguasai alat-alat produksi, mendominasi produksi kebijakan dan penentu utama penetapan aturan main pengelolaan Danau Tempe dibandingkan dengan nelayan tradisional. Asimetri kekuasaan antar aktor ini berdampak pada ketimpangan penerimaan manfat dan nilai alokasi sumber daya di Danau Tempe. Aktor Nelayan Besar dan Pemerintah Daerah mendapatkan manfaat dan nilai sumber daya alam lebih banyak. Sementara aktor Nelayan Tradisional mendapatkan manfaat dan nilai sumber daya alam lebih sedikit. Dalam tahap tertentu, aktor Nelayan Tradisional mengalami proses peminggiran.This paper aims to explain the power asymmetry as a paradox in collaborative management (co-management) of natural resources in Lake Tempe, South Sulawesi. This study uses a qualitative research method with an explanative case study approach. Data collection using participatory observation and indepth interviews. The key informants came from elements of local government, big-scale fishermen, traditional fishermen, farmers, traders, and NGOs. The results of the study concluded that the management of Lake Tempe was marked by asymmetry or power imbalances between actors. Big-scale fisherman actors together with the local government control the means of production, dominate the production of policies and determine the main determinants of the management of Lake Tempe compared to traditional (small-scale) fishermen. The asymmetry of power between these actors has an impact on the imbalance in the benefits and value of resource allocation in Lake Tempe. Big Fisherman Actors and Local Governments get more benefits and value from natural resources. Meanwhile, traditional fishermen actors get fewer benefits and value from natural resources. In a certain stage, the traditional fishermen actors experience a process of marginalization
Population dynamics of pronghorn spiny lobster (Panulirus penicillatus) in Palabuhanratu Bay, Sukabumi, West Java
Get PDFPronghorn spiny lobster (Panulirus penicillatus) is one of the dominant lobsters and has high economic value. The fishing activities are conducted continuously and put aside the preservation of these resources. This study purposed to analyze the population dynamics of pronghorn spiny lobster (Panulirus penicillatus) in Pelabuhanratu Bay, Sukabumi, West Java. The data were collected from January until December 2016 with samples from local fisherman. Lobsters were measured carapace length and total weight. Data analysis included the relationship between length and weight, growth parameters, recruitment patterns, mortality, exploitation rate, length at first maturity or incubating eggs (Lr), and length for first capture (Lc). Panulirus penicillatus from the Palabuhanratu Bay has growth pattern of a negative allometric in both males and females. The asymptotic carapace length (CL∞) of males is higher than females while the growth coefficient (K) of males is lower than females. The peak recruitment for males is expected to be in April and July, while for females in May and August. The total mortality rate of males is higher than the natural mortality rate and vice versa for females. The male lobsters have occurred overexploitation, while females have not occurred overexploitation. The female lobsters have an Lr <Lc value which indicates that the female lobsters are caught after incubating the eggs
Model Sistem Dinamik untuk Strategi Pasokan Air Berkelanjutan di Area Sentul City
Get PDFGood management of water resources is a requirement for an area that has a high population development. Sentul City, which is an independent city in Bogor Regency which has a high population, is in an area that lacks water, because of this Sentul City requires infrastructure and policies that are able to ensure the availability of water for its residents. One of the paradigms of water management in urban areas is a water sensitive city. One of the steps in this paradigm is wastewater management and rainwater harvesting. The dynamic system modelling method is used to predict the impact of implementing several policies that will be taken to manage water resources. The objectives of this study are to build dynamic models to predict water supply and demand and to analyze policies for wastewater management and rainwater harvesting. Sentul City water demand is estimated will reach 122 105 000 m3 and a water crisis will occur in 2027. The wastewater recycle policy can inhibit the water crisis until 2030 and the negative water balance will last until 2040. Combining wastewater recycle and rainwater harvesting can increase water availability by 240% and prevent a water crisis
