Runner which consist of a number of blades is the main component on Pelton turbine when the turbine rotates because the force of water at high speed out of nozzle. Impulse reactions occur because the water jets hit the blades causing torque of turbine shaft causing runner will continue rotates for object hit the blades. Experimental assessment was conducted to investigate effect of nozzle diameter variations as a media to transmit water and runner diameter variations as the main media for generating mechanical energy in power and efficiency of the Pelton Turbine models in Fluid Laboratorium August 17, 1945 University of Surabaya as a prototype model of Micro Hydro Power Plant ( MHPP ). Stages of research was done by designing and planning some variation of the nozzle diameter and runner diameter with reference using head and flow capacity of available water pump. Specified parameters and variables used for experimental assessment is single nozzle with diameter 0,006 m and 0,009 m and runner with diameter 0,15 m, 0,17 m and 0,19 m. Blades used half cylinder shape with the specifications, width 0,036 m, length 0,027 m, depth 0,00081 m, blade gap width 0,001 m, and the distance of center water emmision to blade tip 0,00135 m. From the test results, variations of nozzle with diameter 0,006 m and runner with diameter 0,15 m produces the largest turbine power 49,53 watt, the best turbine efficiency of 87,97%, and the largest generator power 10,56 watt. Meanwhile, the variation nozzle with diameter of 0,009 m and runner with diameter 0,15 m, generating the best generator efficiency 52.43%. From the characteristics graph of Pelton turbines, found same trend with the theory that the efficiency of the turbine decreasing after reaching the maximum efficiency speed ratio of 0,46 and higher turbine efficiency directly proportional to turbine power produced.

Cardboard waste is one of the wastes that can be reprocessed into a useful handicraft. By empowering existing human resources in Jarak Village, Plosoklaten District, Kediri Regency, this Community Service activity is carried out by providing entrepreneurial insight, providing training to make handicrafts from cardboard waste. As a result of this activity, the community in the Jarak Village, Ploso Klaten District, Kediri Regency, got additional entrepreneurial insights which included how to obtain raw materials, production techniques, and product marketing.

The data collection done by distributing questionnaires to the respondents, that are auditors at the BPK was representative of the Province of East Java. Professional skepticism is measured using a scale of skepticism from Hurtt (2010), experience is measured from the length of service as an auditor, independence is measured by indicators of professional independence from Sawyer (2006), ability to detect fraud is measured by fraud symptoms from Fullerton and Durtschi (2004). Result of the regression analysis indicate that each independent variable, that are professional skepticism, experience, and independence, partially has an effect on ability to detect fraud. The implication of this study is that BPK auditors Representatives of the Province of East Java need to increase their professional skepticism, audit experience and a...
