Abstract

Intergrated Forest for Conservation Education of Wan Abdul Rachman (IFCE WAR) Great Forest Park is a conservation forest zone which has natural area and cultivated area.  The natural area in Wan Abdul Rachman Great Forest Park consists of secondary forest, whereas the cultivated area consists of agroforestry with cacao plants and agroforestry with coffee plants. The different land use in both areas caused the difference in carbon sink specifically in litter and soil. The research was aimed to study the difference of litter and soil carbon stock in natural and cultivated area in IFCE WAR Great Forest Park.  The observation plots included in the current study was determined using purposive sampling method. The research was conducted in June until August 2015. Data was analyzed using analysis of variance and continued with honestly significant difference test. The results showed that there was no difference of litter carbon stock in cultivated area and natural area in IFCE WAR Great Forest Park, whereas the soil carbon stock in natural area was higher than that in cultivated area.

Abstract

The purpose of this study was to develop a model of poverty eleviation in the buffer zone of National Park through the optimization of the impact of the fuel subsidiary reallocation (BLT), statrted from April to October 2013 in three villages which representent ethnic culture in Lampung, Java, and the mixture of both, selecting 50 poor households (RTM) who received BLT (direct cash assistance) in 2005. In-depth interview was conducted to capture the economy performance of each household. Qualitative probability model was applied to the response variable (Yi) that were scored 1 for those have been exited from the poverty and scored 0 if not yet. The predictor variables used (Xij) including: fuel prices (Rp/liter), total of BLT (Rp), demographics (age, sex, family head education, as well as the number of dependents), the value of productive assets (Rp million/household), revenue from damar resin, and other sources (Rp million/household), access to public services, the distance to the border of BBSNP, the availlability of PNPM (national project of community empowermnent that scored 1 if any and 0 if not), the performance of social capital and the extention program conveyed. The Minitab Version 16 was employed for exzamining the goodness to the model and the significancy of the parameters pursued at the level of 5% and 10%. The conclusions were the exit capability against poverty were significantly affected by: fuel prices, the ammount of the BLT, the exisistency of PNPM, gender & education of household, number of dependents, the distance to central districts, the presence of electricity, the power of social capital, land ownership of both damar agroforest and paddy field acreages, the owner of productive assets such as ruminants. Accordingly, there were no culturetribe significantly affected by the existing from of poverty, which means that the poverty in this region was more structural cause than that of the cultural one.

Abstract

Open Dumping and inadequate landfill management and waste management have negative impacts on the community. Failure to manage waste in Metro City is not only due to technical weaknesses, lack of financial support, inefficient management agencies, and inappropriate systems can cause Emotional Mental Disorders (GME) as well as densely populated settlements, slums, poor ventilation, damaged house buildings, damp and moldy walls of houses, to the presence of pests around the house can cause anxiety to mental disorders. Researchers evaluated the presence of landfills in 23 Karang Rejo Metro cities, so that the existence of landfill can be in accordance with the prevailing rules. The research method used is qualitative, researchers decipher words in the opinion of respondents descriptively. In addition to interviews, to strengthen the data sought, researchers took pictures and made observations to the community with inter-community interactions, how people live environmental and social lives. Garbage disposal technology has developed, one of the development of the waste disposal method is the Sanitary Landfill method, with the Reusable Sanitary Landfill (RSL) model. The way the supply method works is that the garbage is stacked in a land, then the garbage can is compacted as a ground liner. Ground liners are coated with geomembranes, this layer that will withstand the pervasiveness of lindi into the soil and contaminate groundwater. On top of the geomembrane layer is another geotextile that serves to hold the dirt so that it does not mix with lindi water. The limitations of perspective in the study because the study lies in the small sample, it is suggested it is necessary to do more research by comparing some cases with different concepts.

Abstract

DHF is still a serious problem, especially in children in endemic countries. An estimated 3,6 billion people are at risk and 21,000 deaths each year. Indonesia, in 2018 there were 65,602 cases (IR=24,75 per 100,000 population), with the death of 467 people (CFR=0,71%), and 85.6% of districts in Indonesia reported dengue cases. The climate becomes one of the environmental factors that play a role in the number of cases. Google scholar is used as the main source for finding articles related to DHF and climate published during 2015-2019. The inclusion criteria set forth, are articles that must be published in international journals, published in 2015-2019, must discuss Indonesia, and must assess the effect of climate change on DHF. A total of 52 articles were found, but only 6 articles met the inclusion criteria. Using various analytical methods, all articles obtain climate variability related to the incidence of DHF, through vector abundance. The dynamics of DHF is a very complex system, so it is necessary to combine additional factors other than climate to predict it. The development of an early warning and monitoring system is important, in addition to strengthening the role of households in controlling DHF.

Abstract

The Siamang, Symphalangus syndactylus, an arboreal black-furred gibbon member of the family Hylobatidae is listed as an endangered species by IUCN since 2008. The main threat to Siamang is the degraded habitat in term of quality and extent due to fragmentation. Protected forest Register 28 Pematang Neba located in Kabupaten Tanggamus is an example of the Siamang habitat threatened by the surrounding land conversion. This study aimed to determine the vegetation structure and profile of the Siamang habitat and to determine the diversity and abundance of plants the diet of Siamang. This study was a survey, and the observation was conducted from July to August 2017 applying three belt transect in the Protected Forest Register 28 Pematang Neba. The vegetation structure and profile of the Siamang habitat showed the distance between trees was more than 4 m that influence the Siamang activity in foraging, resting, and playing. The IVI showed a moderate category at the level of 130.813%, 135.948%, and 122.98% for habitat 1, 2, and 3 accordingly. The diversity index showed a moderate category at the level of 2.905 and 2.762 for habitat 1 and 2 respectively, and a high category for habitat 3 at the level of 3.066. The similarity index values among habitats were considered high (69-81%) allowing Siamang to migrate between habitats. The variety of Siamang diet was composed of leaves, fruits, and flowers.

Abstract

Rice is is one of the food crops sub-sector commodities that are most affected by climate change. The negative impact of climate change on lowland rice is the decline in production and productivity due to changes in planted area and harvested area. The purposes of this study is to analyze the adaptation strategies of irrigated and rainfed farmers in facing climate change. The study was conducted in Palas District, Candipuro District, and Sidomulyo District, South Lampung Regency from June to September 2020. The sample in this study consisted of 100 farmers with details of 50 irrigated rice farmers and 50 rainfed rice farmers. Data were analyzed descriptively, presented in percentage form and then narrated. The results showed that the adaptation strategies adopted by irrigated and rainfed rice farmers in the face of climate change include adapting the use of rice varieties, adjusting planting time, using boreholes, diversifying income outside the agricultural sector, and participating in agricultural insurance programs. The majority of irrigated and rainfed rice farmers have the same pattern in implementing adaptation to climate change, but irrigated rice farmers apply more adaptation strategies in the form of adapting the use of rice varieties, using boreholes, diversifying income outside the agricultural sector, and participating in agriculture insurance program.

Abstract

Air is an important component for the survival of living things, especially humans. However, air quality has decreased due to pollution. The harmful elements that enter the atmosphere are Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Particulates (PM10), and Ozone (O3). Noise is defined as unwanted sound or sound so that it disturbs and endangers health. Sources of noise are divided into moving and stationary noise sources. The method used in this research is grab sampling by installing an air sampler impinger to capture particles or pollutants as well as taking noise data using a simple method with a Sound Level Meter with a reading every 5 seconds within 10 minutes for one measurement. The results showed that the air quality in residential and workspace areas was still within quality standards. The noise level in residential areas is still acceptable, but the noise level in the production room surpasses the acceptable limit.

Abstract

Recycling metal scrap is an effort to save The earth from pollution, meanwhile in the process of recycling metal scrap usually it took a lot of water in the process to cooling it from such a high temperature. The purpose of this study was to identified water quality from the water in the reservoir and the water quality of the river that indicated receiving overflow from reservoir water when in the rainy season. The study was conducted from October to November 2020 at the Melting Scrap Factory and the river around the industrial zone. The study was conducted by taking a water sample for analysis in the spot (in-situ) and in the laboratory (ex-situ). The water sample was taken by a field technician laboratory. The result from laboratory analysis counted to indicate the water quality using Pollution Index methods (PI).and then in order to detect pollution from the fish that lived inside the pond using nutrition value coefficient (NVC). After the analysis data was counted the result showed that the water-saving pond had 3,20 values for pollution index(PI) and the river had 3,71 values for pollution index(PI), both of the results indicated that status water quality was classified as lightly polluted if it referred to the policy KEPMEN LH NO 11 Tahun 2003 for standard water quality class 3. Based on the data that has been counted for NVC the result was 1,84, it showed that the fish could live healthily but for further analysis laboratory on the fish meat, it showed that the fish meat was contained a high amount of a heavy metal compound such as iron (Fe) which had value over the standard (1953 mg/kg), from that value it showed how polluted the fishes in the reservoir. The fish should not be eaten by humans because of the high amount of heavy metal compound
