The Effectiveness of Zakah, Infaq, Sadaqah (ZIS) Management by BAZDA to Improve the Welfare of Society in Central Java

The big potential of Zakah, infaq, and Sadaqah (ZIS) in Central Java is one of the instruments for reducing poverty and improving the welfare of the society. This study aims to assess the effectiveness of management ZIS optimally so as to make a significant contribution to poverty reduction and improved well-being. Regulation No. 23 of 2011 on the management of Zakah has provided the legal basis which is very strong in the management of Zakah, by collecting, distributing, and accountability of it.The unit of analysis in this study is the Bazda in Central Java Province. The sample is four districts/cities, including: the city and regency of Semarang, Jepara and Demak district. In addition, the study respondents aremanagers of Bazda, muzzaki, and mustahik in four districts/cities.The findings show that all Bazda have already had database on muzaki and mustahik, but still incomplete, so it cannot be done for the sake of collecting and mapping the distribution of ZIS effectively and efficiently. Moreover, the condition of the building, infrastructure and operational funds sourced budgets have not been able to support the operations and performance of the collection, distribution and reporting effectively and efficiently. Distribution and utilization of ZIS is dominated for the fulfillment of consumer needs and focused on the areas of health, education and social, while, empowering productive business activities is still slightly low, so that it is necessary to have a paradigm shift in the management of the ZIS to make mustahikbecome more productive. It is required a coordinated and integrated cooperation between Bazda District/City, Baz Districts, the regency/state, enterprises, SOEs and private agencies in order to collect ZIS effectively and efficiently and not only dominated merely by the civil servants. Reporting and accountability system, so far, has been conducted in a transparent and accountable through a written report to the District / City Government and Parliament, but some Bazdado not provide it to mustahikin detail, either in book form or through the WEB. Only the district of Jepara which has a complete reporting system, regular, detailed and printed in book form to be sent to the Government, Parliament, and the muzaki of related parties

Integrasi Budaya Jawa Pada Pengembangan Bahan Ajar Bumi Dan Alam Semesta

Kesulitan siswa dalam mempelajari IPA salah satunya disebabkan oleh sebagian besar materi IPA diadopsi dari sains Barat. Padahal budaya yang mendasari pengembangan sains Barat tidak sama dengan budaya Jawa, maka pembelajaran sains berpotensi menimbulkan kesenjangan (clash) dengan sains lokal. Kesulitan lain disebabkan oleh pembelajaran IPA selama ini dilakukan memisahkan antara konten IPA dan pedagoginya. Penelitian ini bertujuan untuk mengintegrasikan Budaya Jawa dalam pembelajaran IPA yang meliputi proses dan produk (materi) IPA menjadi satu kesatuan pengetahuan (Pedagogical Content Knowledge/PCK). Metode penelitian ini adalah penelitan pengembangan (R&D). Tahap-tahap penelitian meliputi (1) studi pendahuluan; (2) pengembangan PCK; (3) validasi PCK; dan (4) pengembangan produk. Hasil penelitian menunjukkan modul yang dikembangkan layak untuk diujicobakan pada tingkat yang lebih luas dalam perkuliahan Fisika Sekolah Menengah. Western-adoption of most material of science causes student's difficulties in learning science. Meanwhile, the culture base of Western science development is different from the Javanese one. This is why science learning causes potentially clash to local science. Other difficulty is caused by learning science which has been done by separating content from its pedagogy. This study aims to integrate Javanese culture into science teaching that include process and product to become a unified science knowledge (Pedagogical Content Knowledge/PCK). The research method used was a research & development (R & D), with the stages of (1) preliminary study, (2) development of PCK, (3) validation PCK, and (4) product development.

The Effect of Temperature and Addition of Cao to Hydrogen Production From Pattukku Coal Char Gasification

Hydrogen is an environment-friendly fuel and has a high caloric value. Hydrogen as a molecule is not found in nature, but it is found in compounds with other elements. Besides catalytic steam reforming of natural gas, hydrogen can also be produced from thermochemical processes such as combustion, pyrolysis, and gasification. The process of gasification using steam as gasification agent can increase the yield of H2 in the gas products. The objectives of this research are to study the influence of temperature and the addition of CaO on H2 production. This research was conducted in an up-draft reactor for 60 minutes with three different temperatures; i.e. 600, 700, and 800 oC and ratio of CaO:char of 0 and 0.5. Based on this study, the rise of temperature will improve the yield of H2 and CO2 in the gas products. At gasification temperature of 800 oC, the yield of H2 and CO2 is maximum. Moreover, the addition of CaO can improve the char conversion and reduce the concentration of CO2 in the gas products

The Synthesis of Glycerol Carbonate From Biodiesel by Product Glycerol and Urea Over Amberlyst 15

The growing utilization of biodiesel as a renewable fuel has generated a large surplus of glycerol as a major byproduct. The prices of glycerol continue to drop in such an oversaturated market. Therefore, new uses are being developed for glycerol to produce value-added chemicals. Among those chemicals, glycerol carbonate has many application in various fields. Glycerol carbonate is mostly used as a solvent in cosmetic and pharmacheutical industries due to its low toxicity, high boiling point, and low vapor pressure. The synthesis of glycerol carbonate from glycerol and urea using Amberlyst15 as a catalyst was being conducted in this study. The reaction was carried out using a batch reactor for 5 hours with the condition of the reaction temperature was around 120oC, mole ratios of reactant of urea:glycerol were 0.8:1, 0.9:1, 1:1, and 1.2:1 , catalyst concentrations were 2%, 2,5%, 3%, and 4%, and mixing speeds were 370 rpm, 525 rpm, and 700 rpm. It is found that the optimum conversion of glycerol was obtained at 120oC with 5 hours of reaction using an equimolar amount of glycerol and urea with catalyst load of 3%. Mixing speed did not affect glycerol conversion. Amberlyst15 as catalyst was also stable enough to be reused at least for three times
