Conversion of Degradable Solid Waste into Alternative Energy using Local Wastes as a Binder, Case of Southwestern Ethiopia
Abreham Bekele Bayu Jimma University Jimma Institute of Technology JIMMA ETHIOPIA , Ketema Beyecha Hundie Jimma University, Jimma Institute of Technology, School of Chemical engineering Jimma Ethiopia EthiopiaThe objective of this research is to produce high quality of charcoal from the most known local wastes as a binder. The solid waste was collected from Bonga city and the production of charcoal briquette based on different binder preparation. The local wastes like sawdust and paper were used as a binder comparing with starch as a standard binder. Since the result obtained by using sawdust shows better burning time and less smoke comparing with using paper as a binder. The proximate analysis result obtained for degradable solid waste was its density, percentage of moisture, volatile matter, ash, fixed carbon, and caloric value of 16.73 kg/m3,17.81%, 67.56%,4.78%, 9.85% and 18.39MJ/kg respectively. In the same way, fuel briquette using sawdust as a binder was characterized for its density, percentage of porosity, weight index, shatter resistance, moisture content, volatile matter content, ash content, fixed carbon content, and caloric value which is 750.06Kg/m3,29.05%,92.38%,9.87%, 29.6%, 3.56%, 56.97% and 27.38 MJ/kg respectively. Using sawdust is better than using paper as a binder since the briquette produced by using sawdust as a binder shows less smoke and higher burning time. This shows that it is possible to convert solid wastes into fuel briquettes using local wastes as binders.

Muhammad Abduh Abduh Tamansiswa University Indonesia , Dedik Budianta , Arinafril Arinafril , Lili ErinaTo simplify the description of the damage phenomenon to the earth, the concept of ecological footprint can be used. This concept is not specifically built to calculate the destruction of the earth. This concept calculates how much space (on land and water) humans need to produce the resources they need including absorbing the waste they produce. This study calculates the ecological footprint in Palembang and its surroundings according to demographic factors and local government.  To investigate the general pattern of ecological footprint and its determinants based on the respondents’ reports, a survey was launched in October 2017. As a result, the average ecological footprint in Palembang Metropolitan and its surroundings is 0.591 global hectares (gha). The ecological footprint in Palembang Metropolitan and its surroundings is formed by 4 things, namely: diet and food choices, shelter/home life, transportation and lifestyle choices. The largest portion is given by diet and food choices (26.8 percent), while the smallest contribution is contributed by transportation (24.1 percent).   Taking into account demographic factors, a high ecological footprint is owned by a group of male individuals, aged 30-39 years, highly educated, working, and after hearing and understanding climate change and ecological footprint. Finally, if observed according to the type of government, metropolitan cities have a high ecological footprint than others. Finally, the ecological footprint of Palembang as a metropolitan city is higher than the others.Pages: 142-150Views: - Downloads: -Production Area (Concessions) Role on Landscape Environment Management in South Sumatra
Edwin Hermawan Graduate Program Sriwijaya University Indonesia , Moh. Rasyid Ridho , Muhammad YazidGap existing in the landscape are partial practices on environment management and social programs from each of landscape stakeholders which cause cumulative duplication or incontinuity between programs. The objective of this research is to analyze production area role in the landscape environment management in South Sumatra particularly Musi Banyuasin and Banyuasin Districts. Using survey method and purposive sampling, 8 companies representatives are interviewed regarding current environment management system and the relation with external factors with landscape approach overview. The results: (1) Land-use planning should be in place prior the development of concession permit and concessions as implementer of provincial and national agendas on local investments; (2) Concession monitoring efforts could give input on the conformity towards the law enforcement in environment management which should be expressed through the year.; (3) Concessions ideally have the role as connector to community and protected areas, connecting to government programs, raising awareness as well as providing assistance in economic empowerment to the community, reducing dependency towards forests; (4) The report from wildlife and its habitat monitoring (buffer area) surrounding concession should also be shared with Environmental Agency (DLH), Forest Management Unit (KPH), National Park and Natural Resource Conservation Center (BKSDA) for potential or existing wildife corridors or ecosystem essentials area; (5) Concession could collaborate with conservation area as well as other governmental programs to maximize the impact and efficiency of the programs. Together with community and protected areas, concessions have significant area size and have the capacity and resources to also take part in the landscape management. Joint monitoring and programs would be tremendous achievement for the landscape approach.Pages: 151-155Views: - Downloads: -Effect of Family, Community and Education Environment on Prevention of Drug Abuse in High School Students

Indonesia , Jun Harbi Forestry Economics and Management Department, Faculty of Economics and Management, Northeast Forestry University, Harbin, China IndonesiaCalculation and estimation of carbon stocks in various types of forests and ecosystems in Indonesia has been widely practiced. However, the availability of carbon stock information for some locations in the remaining forest area in South Sumatra Province is still very limited. This study aim to measuring the carbon storage potential and the ratio between the carbon storage value derived from the interpretation of satellite imagery and the storage of carbon stock from the field calculation. The method used is to calculate the estimation of carbon stock through satellite imagery interpretation and field measurement. The largest estimation of carbon stock through satellite image interpretation was found in secondary forest cover type with yield 896,234 ton/c/ha, followed by plantation land type with a yield of 147.104 ton/c/Ha and the smallest is open land cover with value yield of 2.883 tons/c/ha. While carbon stocks through field measurement yield 429,181 ton/c/ha of secondary forest cover type, followed by plantation land type with 41,169 ton/c/ha and 4,283 ton/c/ha for open land type. A comparison of carbon stock estimates of the two approaches used, yielding a reference value of 220%. These comparative values can be used to assist in carrying out initial estimates of carbon stocks in some types of land cover, especially for lowland forest types.

Nofriya Nofriya Sekolah Tinggi Teknologi Industri Padang Indonesia , Ahmad Fadhly Sekolah Tinggi Teknologi Industri Padang IndonesiaOne of the development missions of Padang Pariaman Regency is to increase the potential for regional competitiveness through the development of tourism, transportation, trade, spatial planning, and environmental management. However, in the tourism policy has not seen the synergy of developing tourist destinations with environmental sustainability. This study evaluates physical integrity indicators in tourism activities in Padang Pariaman Regency to achieve environmentally sustainable development. This research uses a qualitative approach. Data were collected using in-depth interviews, document reviews, and observation of tourism objects. Data analysis was carried out by analyzing the themes and contents by triangulating the interviews' results, observing the results, and reviewing the documents. The results showed no special permit regarding environmental sustainability for tourism activities. However, each tourist attraction had its policy to protect the surrounding environment. The community is empowered to manage tourist objects and have local wisdom as a code of ethics in safeguarding the tourist area. The regional landscape is still preserved, but the beach's tourist objects are vulnerable to abrasion disturbances. It is recommended that the government make a policy to defend the physical integrity of the tourist attraction sites so that the concept of environmental sustainability can be achieved.

Dwi Wahyuni Sriwijaya University Indonesia , Dewi Ratna Sriwijaya University Indonesia , Saloma Saloma Sriwijaya University IndonesiaSoil reinforcement method is one of attempt to improve technical characteristic from the soil, such as soil bearing capacity, compressibility and permeability. The Soil Column Method is one of alternatives to enhance physical characteristic by way of stabilization to improve soil bearing capacity. Rice Husk Ash (RHA) contains high silica element, Calcium Carbide Residue (CCR) contains high calcium which is able to form pozzolan when mixed upon silica. This research aims to improve soil bearing capacity by using column soil method with a mixture of soft soil, 3% Calcium Calbide Residue (CCR) and 12% Rice Husk Ash (RHA). Soil column in this research applied a single column variation with a diameter of 3,2 cm which each has 40 cm, 46 cm, and 53 cm in length and each column with diameter of 3,2 cm, 4,2 cm, and 4,8 cm. Based on the research, ultimate Bearing Capacity (qu) of soft soil without soil column was 54,03 kPa and after being given reinforcement had increased the bearing capacity value (qu). The greates increase in soil bearing capacity of the soft soil occurred in soil column variation of 53 cm in lenght with 4,8 cm in diameter where the soil bearing capacity had increased to 75,58 kPa and the percentage increase in BCR was 39,90%. Meanwhile the least of soil bearing capacity occurred in soil column that had 53 cm in length and diameter of 3,2 cm while the soil bearing capacity had increased to 64,47 kPa and BCR only increased to 19,33%Pages: 172-177Views: - Downloads: -Carbon Storage Estimation in Mangrove Sediment at Payung Island, South Sumatera
Septi Hermialingga Sriwijaya University Indonesia , Rujito Agus Suwignyo , Tengku Zia UlqodryMangrove is a plant generally located in tropical regions. It grows in areas with salinated to fresh water and affected by tidal along with anaerobic soil conditions, where many grow in areas that are filled with mud and contain organic material. In the process of photosynthesis, mangrove captures carbon in the atmosphere and are stored in biomass and sediment. Sediment can store carbon greater than biomass and is rich of organic matter. Research regarding carbon storage in mangrove sediment on Payung Island has never been carried out which made this research aimed to estimate carbon storage in mangrove sediment on Payung Island. This research was conducted in October 2020 on Payung Island, South Sumatra and sediment samples were analyzed by the Walkley-Black oxidation method and the sediment texture was analyzed by the Shepard triangle method. The calculation results show the dominant sediment texture was in the clay category, the average value at each station for % C organic is 5,04% and % organic matter is 8,18% and carbon deposits in sediment are 129,6 tonC/ha.
