Abstract

There is a lot of coal ash waste in Indonesia because most power plants in Indonesia still use coal. And Indonesia produces quite a lot of plastic waste because most people use plastic in their daily lives. Plastic waste and bottom ash can be used as raw materials in the manufacture of paving blocks. The objective of this study is to find out the quality of paving blocks, comply with SNI 03-0691-1996, and find out whether the composition of the bottom ash and plastic waste affects the compressive strength and water absorption. The paving blocks to be made are 10 cm X 10 cm X s10 cm with 5 (five) different types of composition, each composition will have 2 (two) paving blocks, and the drying time is 14 days. This final project uses experimental methods, and T-test, analysis of variance (ANOVA). T-test testing is carried out on each type of quality, namely the quality of A, B, C, and D. 5 different types of compositions produce different qualities, namely the average compressive strength of composition 1 to 5 in order are, 4.76 MPa, 11.56 MPa, 11.4 MPa, 7.65 Mpa and 10.13 MPa. And for water absorption the average water absorption in composition 1 to 5 in order are, 2.08%, 2.16%, 2.18%, 3.12%, and 4.14% . From the T-Test result, paving blocks with compositions 2,3, and 5 have D quality because their compressive strength has complied with D quality even though the water absorption has met A quality. It means paving with compositions 2,3, and 5 can be used as building materials for the garden. And paving blocks with compositions 1 and 4 have A quality, so people can be used as materials for roads. Based on the ANOVA result, the factors of plastic waste and bottom ash significantly influence the compressive strength and water absorption quality.

Abstract

Abstract. The economic and environmental sectors often have differences and tend to be contradictory. Ecotourism is one solution in resolving the conflict between the economy and the environment. However, if it is not managed properly, it tends to cause inequality in one of its dimensions. Purpose: to examine the sustainability status of Boonpring ecotourism through several dimensions. Methods and Results: The method for assessing sustainability status uses MDS (Multi Dimensional Scaling) with Rapfish (Rapid Apprasial Index) which is modified into Rapecotourism. The value is obtained from the attribute assessment on each dimension consisting of the ecological dimension, the economic dimension, and the human resource dimension. Sustainability parameters consist of (0-25.00%) not sustainable, (25.01-50.00%) less sustainable, (50.01-75.00%) moderately sustainable, (75.01-100%) very sustainable. Then proceed with leverage analysis to determine the sensitive attributes that play a role in determining the sustainability of a dimension. Result: The sustainability analysis of Boonpring Ecotourism shows that the ecological dimension (54.46%), the economic dimension (63.79%), and the human resource dimension (61.03%) all have sufficient sustainability values. Conclusion: Boonpring ecotourism is quite sustainable, with a note that there are several lever attributes that must be improved, such as regulations related to ecotourism management which must be ratified immediately, so that ecotourism can become very sustainable.

Abstract

In Indonesia, the waste bank is an urban infrastructure that is a solution to reduce the volume of waste that goes to the landfill (TPA). Various types of concepts that develop in the waste bank, make local residents more skilled in processing waste and can increase family income. In relation to concept innovations that have developed in several regions in Indonesia, one of the influencing factors is the perspective of the initiators who form the basis for the development of these concepts. The waste bank initiators have a perspective in responding to the concept that has been formed from the beginning of the emergence of the waste bank. The initiators aim to innovate in order to attract more customers in new ways.

Abstract

Production of organic waste that is dominating waste generation becomes a problem for the environment. Eco enzyme is a solution made from brown sugar, water, and fermented fruit waste. Eco enzyme can become one of solution to reduce waste generation. Eco enzyme utilize organic waste recycling and brown sugar as the fermentor. This solution can be utilized into multipurpose cleaning liquids, eco enzyme also can reduce the wastewater contaminant, it can reduce effect of wastewater after dispose to the environment. This research has purpose on determines the characteristic of the guava eco enzyme and the correlation on the reduction of NH3, pH, and PO4 in water. The research results show that the guava eco enzyme is acidic with pH 3.36, it also containing 1.4 ppm of NH3, 11.2 ppm of PO4, and 116800 mg/l of COD. From the observation in the variation of time eco enzyme can reduce NH3 and PO4 also pH value. With 2% of guava eco enzyme concentration, it can reduce 27.5 % of NH3 with eight hours observation and 20% of PO4 contaminant in the water in 6 hours observation. From the analysis of guava eco enzyme, resulted that a higher concentration of an guava eco enzyme can reduce higher contaminant. With higher concentration of eco enzyme which 5%, 7%, and 10% it can reduce 28.3%, 30.1%, and 31% of NH3. From correlation analysis there is strong correlations between NH3 and pH reduction percentages with a concentration of eco enzyme added to the water.  A small amount of guava eco enzyme also effective in reducing the pH of the water. It can reduce until 50% of pH by 2.4% eco enzyme concentration. This finding may contribute as the baseline for further improvement of household wastewater pre-treatment.
