Wastewater produced by the tempeh industry contains a high organic content, so it requires serious handling so as not to cause pollution in water bodies. One method that can accelerate the decomposition of the organic substance process is to use Lactobacillus sp. bacteria as effective microorganisms (EM). The material used to manufacture EM is sourced from kepok banana peel waste, which has a carbohydrate content of 9.8%. This study aims to examine the effect of EM concentration and residence time on reducing pollutants in tempeh wastewater using EM made from kepok banana peel waste. The EM concentrations were 0%, 10%, 20%, and 30% successively, with residence times of 0, 4, 8, 12, and 16 days. The researchers used a batch system in a 5-litre plastic tube reactor with an aeration system. The results demonstrated the effectiveness of adding EM from kepok banana peel waste in reducing Chemical Oxygen Demand (COD) levels. Specifically, a 20% dose of EM resulted in a 78.13% removal, a 30% dose of Biological Oxygen Demand (BOD) led to a 78.01% reduction, and a 10% dose of Total Suspended Solid (TSS) resulted in a 66.81% removal over an optimum residence time of 16 days., Wastewater produced by the tempeh industry contains a high organic content, so it requires serious handling so as not to cause pollution in water bodies.

This research is proposed to identify marketing strategic of Samarium ethylenediaminetetramethylene phosphonic acid (Sm 153-EDTMP) that is used for palliative treatment of bone metastasis towards utilization policy by the Nuclear Medicine Doctors. The data is obtained from the questionnaire that were spread out to Nuclear Medicine Doctors in a number of Hospital in Indonesia as respondents. The respondents were 35 of Nuclear Medicine Doctors. This number represents 80 % of Nuclear Medicine Doctors population in Indonesia. The research methodology is accomplished by descriptive explorative analysis. The results are: (1) dose, side effect of Sm 153-EDTMP that is more tolerating than morphine, (2) according to the local product promotion, Sm 153-EDTMP is able to be delivered more effectively to the user through detailing, symposium, internet (3) the price of the local product of Sm 153-EDTMP that is way more cheaper than morphine. By paying attention to marketing strategies through product advantages, promotional forms and prices SM 153-EDTMP shows that these products can be used by Nuclear Medicine specialists (SpKN) as a palliative treatment for cancer that spreads to the bones.

In the coming year, it is estimated that holiday activities will continue to be part of the lifestyle of the Indonesian people. Traveloka with unicorn status is present in Indonesia as an online travel agent which in 2014 entered the hotel reservation business. Competition is very tight from competitors, Traveloka continues to strive to provide the best for its consumers. Traveloka provides services in the form of reviews, ratings and hotel facilities. The purpose of this study was to determine the effect of: consumer trust on hotel booking decisions, reviews of hotel booking decisions both directly and through trust, ratings on hotel booking decisions both directly and through trust, facilities on hotel booking decisions both directly and through trust. The increasing competition requires each retailer to strive to maintain and even win the competition between retailers by understanding consumer behavior, for online shopping consumers, as much as possible can be used as input or consideration in online shopping, and of course as a reference for future researchers. The population is an unknown number of consumers who have booked hotels on Traveloka. The sample data of 200 were obtained by purposive sampling using google form to obtain primary data. The research design used explanatory research. Data were analyzed using path analysis, where data quality tests were previously carried out. The results showed that reviews had no significant effect on trust, reviews had no significant effect on hotel booking decisions, rating had a significant effect on trustworthiness, rating had no significant effect on hotel bookings, information on facilities had a significant effect on trust, facilities information had no significant effect on hotel booking decisions. and trust has a significant effect on hotel booking decisions.
