Applying Value Creation Framework to Offer Public Transport Improvement

Public Transportation in urban areas is expected to be main choice for people's mobility. The aim of this research is apply value creation framework based on S-D Logic and Trans Jogja from Yogyakarta and Värmlandstrafik AB Sweden are the case study. This research use direct observation and interview to the related person/ company as the primary data, and to support them use group discussion with the users. This research also use secondary data from some journals, reports, documentations, etc. From the analysis and discussion Värmlandstrafik AB is address the value creation service and opportunity more than Trans Jogja. From conclusion, the need of applying value creation framework in Trans Jogja is to offer public transport improvement as has been illustrated by Trans Jogja. Although the achievement of value creation opportunities are not as high as that achieved by Värmlandstrafik AB, but Trans Jogja should learn about what needs should be improved

Identifikasi Dan Uji Potensi Bakteri Lipolitik Dari Limbah Sbe (Spent Bleaching Earth) Sebagai Agen Bioremediasi

Limbah minyak kelapa sawit yang terbanyak adalah SBE (Spent Bleaching Earth), limbah ini mengandung residu minyak tinggi yang dapat mencemari lingkungan, 30% residu minyak pada limbah SBE dapat digunakan bakteri untuk pertumbuhannya, sehingga adanya bakteri mampu menjadi agen bioremediasi pencemaran SBE. Penelitian dilakukan untuk mendapatkan bakteri lipolitik sebagai agen potensial bioremediasi pada limbah SBE. Metode pengambilan sampel limbah SBE secara random sampling. Sampel tanah diambil secara acak dari beberapa titik area limbah SBE. Bakteri diisolasi dari sampel limbah SBE, kemudian dilakukan tahapan yaitu : pemurnian, seleksi, uji potensi, bakteri berpotensi mereduksi lipid dikarakterisasi dan diidentifikasi genusnya. Hasil penelitian menunjukkan bahwa Aktivitas enzim lipase yang tinggi menandakan bahwa bakteri lipolitik bekerja optimal merombak zat pencemar. Bakteri yang memiliki potensi sebagai agen bioremediasi terdiri dari genus Citrobacter (B1), Enterobacter (B2) dan Acinetobacter (B3). The most palm oil waste is SBE (Spent Bleaching Earth), this waste had many reduced lipid that got pollution for inviroments, Bacteria can use lipid from SBE as much as 30% for growed. So that consist of bacteria in SBE as a potensial agent for remediation. This study aims to obtain lipolytic bacteria as a potential agent of bioremediation. The method of sampling soil were taken at random from SBE waste, Bacteria were isolated from the SBE waste, then they were selected into steps : performed purification, selection, potential test, then characterized and identified it's genus of potential bacteria. The results showed that the higest activity enzyme of lipolytic indicated that the lipolytic bacteria worked optimal for reduce polution. Bacteria had potential as a bioremediation agent consisting of genus Citrobacter (B1), Enterobacter (B2) and Acinetobacter (B3)

Analisis Hubungan Ketidakpastian Lingkungan Dan Kinerja Manajerial Melalui Sistem Akuntansi Manajemen

The purpose of this study is to analyze environmental uncertainty relationship and managerial performance with Management Accounting Systems as an intervening variable. The data used in this study were obtained from the manager's perception of marketing, production and finance are functionally involved in managerial performance in manufacturing companies in Banten. The number of questionnaires returned was 41 questionnaire from 150. The data analysis approach Partial Least Square (PLS) using software SmartPLS. This study was conducted at a Manufacturing Company in Banten Province, with the object of study is the manager of marketing, production and finance. This study uses survey research with primary data collection using questionnaires. Selection of the samples tested in this study using purposive sampling, 41 respondents was selected as the study sample. hypotheses testing research with the inner model. The results of this study were (1) A significant positive relationship was observed between and  management accounting system (dimensions of scope, aggregation, integration and timeliness), (2) there aren’t significantly negative between environmental uncertainty with managerial performance, it does not support the hypothesis, and (3) management accounting system is (dimension aggregation and integration) significantly positively related to managerial performance, while management is Accounting System (scope and time dimensions) does not significantly negatively related to managerial performance, it does not support the hypothesis

Synthesis and biological evaluation of benzylideneamino-5H-thiochromeno[2,3-b]pyridin-5-one

Various benzylideneamino-5H-thiochromeno[2,3-b]pyridin-5-one derivatives were synthesized by the reaction of 7-amino-5H-[1] benzothiopyrano[2,3-b]pyridin-5-one and different benzaldehydes. Their structures were confirmed on the basis of Mass, 1H NMR, IR spectra and elemental analysis. These compounds were screened for their antioxidant and antibacterial properties. The results reveal that some compounds have pronounced antioxidant and antibacterial activities.Colegio de Farmacéuticos de la Provincia de Buenos Aire

The Use of Earthworms and Household Organic Waste Composting Length of TIME

Composting with earthworms is composting process by involving earthmacroorganism. Cooperation between earthworms and microorganisms may impact on decomposition process done by the microorganisms as assisted by the existence of earthworms. Because any materials to be decomposed by microorganisms had been decomposed by earthworms earlier, microorganisms would work more effectively and quickly. This study aimed to determine effects of using earthworms toward household organic waste composting length of time by using experimental design of study. The object of study was all organic waste taken randomly from one household. Variable of study was composting length of time measured after addition of earthworms and composting process completed. Tools used in this study were measuring tape, calendar, hygrometer and smelling sensory (organoleptic). Statistical analysis used differ test. Results of study showed data was normally distributed, equality of variance and no difference found between composting length of time with or without using earthworms. In conclusion, there is no relation found between the use of earthworms and the household organic waste length of time
