Abstract

Little known about the safety of natural water on enteric mikroflora population at Mojo Village Padang Distric Lumajang Regency. We assessed the population of enteric microflora i.e Salmonella and Eschericia coli in the wellspring. We performed a randomized sampling to evaluate the population of Salmonella and Eschericia coli of three natural water resource at Mojo Village. There were Jirun, Kali Tengah and Sumber Suko water resource. Medium to colony identification were used Salmonella Chromogenic Agar (SCA) and Enteric Hektoin Agar (HEA). SCA resulted blue colony for Eschericia coli and magentha or violet colony for Salmonella. While HEA resulted orange colony for Eschericia coli and green for Salmonella. 250 mL of natural water was used to growth the enteric microflora. We observed three water resource of Mojo Village contain enteric microflora. The enteric microflora population was up to 2 log10 CFU/mL (more than 10 CFU/mL). These was a fantastic population, because enteric population must no growth on drink water. Assuming the enteric microflora come from fish faecal, because at the surrounding of water resource growth the fish. Three water resource at Mojo Village were no safety to used as drink water if without water treatment. The enteric microflora can dextructed by using filtration and UV treatment or thermal process example water boiling.Keywords: Jirun, Kali Tengah, Sumber Suko, Salmonella, Eschericia coli, water resource

Abstract

This research deals with identification of potential hydrological drought at 15 watersheds in Eastern part of East Java Province. Hydrological drought events is indicated by water deficits at the main river of the watersheds during certain period of record. Discharge data from 15 watersheds in East Java are used as main input for this analysis. TLM modul based on HydroOffice platform is used to calculate the deficit. Deficit event is counted when the discharge during more than > 7 days is below the threshold level. The threshold level is set up using percentile 90% (Q90). The value of Q90 is determined from discharge times series. Furthermore, the discharge is rangked from high to low flow. Results from TLM are then imported to EXCEL for further analysis. Furthermore, GIS software package (Quantum GIS) is used for mapping the spatial variation of discharge values (avarage, maximum, Q90), frequency and duration of deficits events. This analysis produces the spatial maps of discharge value and deficit events ( averaged annually).Keywords: TLM, hydrological drougth, percentile 90 (Q90), discharge

Abstract

Prol Tape is one of the local traditional food products (cake) from Jember, made from fermented cassava. Quality improvement problems were still faced by producers of prol tape. This was due to limited information of consumers’ satisfaction factors of this product. Therefore the evaluation of consumers’ respon was strongly needed to know consumers’ needs in this product. Quality Function Deployment (QFD) was used in this research to reach factors or product attributes related to consumers’ needs of prol tape product. The result of this research found that there were 4 attributes of consumers needs consisted of taste, colour, aroma and texture. There were also five technical responses from producers (production acctivities) which have close relationship to product quality. Compared to other brands, it was found that consumers prefer to select Wika than other brands (Sumber Madu, Primadona and Purnama Jati). From QFD analysis, Wika could reach the target compare to others. It means that Wika has better condition to answer consumers’ needs using tecchnical response. Some of recommended strategies are also explained briefly in this research paper.Keywords: quality, traditional product, QFD
