Leachate of solid waste disposal site contains organic material in high concentrations. The organic matter in the leachate can be reduced by phytoremediation using water hyacinth (Echhornia crassipes). The aim of this research was to determine the effect of coverage area, residence time, and their interactions in reducing the organic matter concentrations in the leachate. The method was a designed experiment, which was based on Completely Randomized Design (CRD) with Factorial Design. The first factor was the percentage of water hyacinth coverage area of 0; 25; 50; 75 and 100%, and the second factor was the length of residence time of 4, 5 and 6 days. Results of this research showed that the coverage area of 75% could remove the BOD and TSS levels up to 53.812 and 62.84% respectively. The coverage area of 100% showed COD removal efficiency of 29.215%, which was the highest when compared to the other variations. The residence time of 6 days was able to reduce the BOD, COD and TSS levels in the highest efficiencies of 49.44; 29.94 and 47.84%. respectively. The combined coverage area of 75% and residence time of 6 days showed the highest BOD and TSS removal efficiencies of 59.19 and 65.14% respectively. Whereas the combined coverage area of 100% and residence time of 5 day system was able to reduce the COD level up to 30.66%.

Waste water treatment is needed to avoid the impact of pollution to the aquatic environment. Techniques for treating waste water, among others, are through phytoremediation using the help of water lettuce (Pistia stratiotes).This research aims to determine the effect of the percent covering area of water lettuce, the length of exposure time, and interaction of both in reducing levels COD, and to determine the percent of covering area, the length of exposure time, and interaction of both that is the most efficient in reducing The result of this research showed that the percent covering area, and the length of exposure time had a very significant effect of decreasing levels of COD. The most efficient percent covering area in reducing COD was in treatment of 75%. The most efficient length of exposure time in reducing COD was in treatment 9 days. The most efficient interaction of both in reducing COD levels was at treatment of 100% coverage area with exposure time of 9 days.

Based on Law No. 6 of 2014, the establishment of village-owned enterprises (BUMDes) aims to encourage and accommodate all activities to increase community income man. The role of BUMDes is to become a pillar of community independence in accommodating community economic activities to improve community welfare, so this research uses a qualitative descriptive type of research. It is said to be qualitative because the main data source in this research is the words and actions of the people who are observed or interviewed. While it is descriptive, that is, the researcher describes an object, phenomenon, which will be written in narrative writing. In terms of place, this research is a type of field research with the hope that BUMDes will be able to create a more efficient society.

Leachate is liquid originated from organic waste. The substance consists of dissolved and suspended materials as a result of decomposition process by microorganisms. Leachate is waste consist of organic and high heavy metal. To manage leachate, heavy metal should be reduced by biosorption. Biosorption is heavy metal adsorbtion by inactive or death organism. The aims of the research were to examine the contact time, Sargassum cinereum biomass, combination of contact time and S. cinereum biomass to adsorb cadmium from the leachate. The experiments were based on Completely Randomized Design (CRD) with Spilt Plot Design. The treatments included contact time of Sargassum cinereum with leachate as main plot and S. cinereum biomass as sub plot. Contact time of S. cinereum with leachate consisted of three levels i.e., 1, 2 and 3 hours while S. cinereum biomass consisted of four levels, i.e., 200, 300, 400 and 500 mg. Data obtained were analyzed by analysis of variance (ANOVA) and followed by High Significant Difference (HSD) test. The results showed that S. cinereum biomass can adsorp cadmium from leachate. The level of adsorption of heavy metal was different in each treatment depending on contact time and S. cinereum biomass. The contact time of 3 hours was the optimum length in adsorping cadmium (39.168%) and 400 mg S. cinereum biomass was optimum amount in adsorping cadmium (38.936%). Combination of contact time 3 hours and 400 mg S. cinereum biomass was optimum treatment in adsorping cadmium (42.289%) from the leachate.

This study is designed to cultivate a primary school curriculum that is particularly related to entrepreneurship. It is vital for primary school students to recognize and be taught Entrepreneurial education earlier as a paramount component in enhancing their independence and competence to seize the opportunities in the era of free marketplace today. Not only is this research driven by the fact that the introduction of entrepreneurial-related professions has been low compared to other professions, but also conducted to explore and stimulate the entrepreneurship values of primary school students, empowering the human resources competence. Entrepreneurial-based curriculum can direct the learning process of both students and teachers possessing indispensable roles to cultivate concepts concerning entrepreneurial activities. This curriculum development, ultimately, becomes a challenge to encounter an economic crisis, as well as, an opportunity to prepare young generations that are not limited to be ready to work but open field work.

Law No. 23/2014 on the Local Government aims at fostering local governments in the country to nurture a culture of innovation to improve the quality of public services. This research attempts to discover paradoxes in the Surakarta City Government related to regulations governing local governments in Indonesia in developing public service innovation. This study uses a qualitative methodology with descriptive analysis related to the paradoxical evidence of public service innovation capacity in the Surakarta City government. Data were collected through in-depth interviews, observations, and literature studies of reputable journals. Furthermore, interviews were conducted with resource persons, from top management leaders to innovation actors, with a total of ten people. We utilised the analysis framework of Public Sector Innovation Capacity Management by Kim and Lee to analyse the results. We used SWOT analysis to devise a public service innovation capacity management strategy in Surakarta City. The results prove that the Surakarta City government has different characteristics in developing public service innovation. However, there is a paradox, which is a contradiction in the course of the local government in general. This paradox is evident in two main phenomena. First, there were no particular government regulations. Second, regional apparatus organisations (OPD) practice less collaborative mechanisms. By contrast, we found that entrenched innovation DNA and an external driver of innovation support the creation of public service innovations in the Surakarta City Government.
