The aim of this study was to evaluate the effects different extenders on motility, membrane and acrosome integrity of post-thawed bull sperm. Twenty ejaculates from four crossbreed bulls were collected. Within 5 min after sperm collection the fresh semen was divided into three groups based on types of extenders; (1) with Tris buffers, (2) with sodium citrate, and (3) with TALP extenders. A computer assisted semen analysis, hypo-osmotic swelling test, and fluorescence isothiocyanate labelled peanut agglutinin (FITC-PNA) techniques were used to determine motility, membrane integrity and acrosome integrity of spermatozoa, respectively, in both fresh ejaculate and frozen thawed semen. The percentage motility, membrane integrity and acrosome integrity in fresh ejaculate were higher than post-thawed. The sperm motility and membrane integrity were no significantly different (P> 0,05) among all extenders. Whereas, the membrane acrosome integrity of spermatozoa in post-thawed was significantly different (P< 0.05) when TALP extender was compared with sodium citrate, and Tris buffer extenders. In conclusion, all extenders resulted in a better sperm motility, membrane integrity after, while acrosome integrity was no significant after cryopreservation.

The use of electric current will be related to heat input. Enough heat input is needed to form a good nugget structure so that it can produce maximum connection strength. The nugget structure is influenced by electrode pressure, holding time and the electric current used. By adjusting the parameters of the amount of electric current, the best connection quality will be produced. The purpose of this study is to determine the effect of variations in electric current on the shear tensile strength of dissimilar welding Stainless steel (SS) and Aluminum (Al). The variation of electric current used is 60 A, 70 A and 80 A. The welding time used is 4 seconds. The test material uses stainless steel material with a thickness of 1.2 mm and aluminum with a thickness of 0.9 mm. This research was conducted at the Kotabaru Polytechnic Mechanical Laboratory and Malang State Polytechnic Material Test Laboratory. Tests carried out are shear tensile tests according to ASME (American Society of Mechanical Engineering) standards. The results showed that an increase in electric current from 60 A to 70 A had an impact on the increase in shear tensile strength. While the increase in electric current from 70 A to 80 A shows a decrease in shear tensile strength. The results of shear tensile testing indicate that the best conditions occur at 70 A electric current which gives a shear tensile strength of 44.109 kN / mm2. The increase in the electric current at the dissimilar welding between Stainless Steel and Aluminum is not directly proportional to the increase in shear stress that occurs. This is because the melting point of each material is different. If the heat generated exceeds the melting point of the material used, the welding results will be damaged.

Exploring information or new knowledge from existing data sets is an important point of the data mining process, such as a collection of course value data that has been stored, but its potential has not been raised to find new benefits. While on the other hand there is the problem of how to find the concentration of studies that are in accordance with the competencies of the students themselves. This study was conducted to find the concentration selection pattern, based on some of the best value data from the courses that have been taken using the Apriori Algorithma, where the rules in this method will be used to find the pattern in question. Using a minimum support value of 70% produces rules with 5 item sets, namely courses in logic and algorithms, system analysis, system design, web programming and software engineering. The pattern / rule produced can be a guide for students in choosing concentration.

Geoelectric resistivity method is one method that can be used to characterize water-bearing rock layers (aquifers). This method is based on the existence of differences in type resistivity in the layers of rock that are flowed electrically. The use of this method is based on easy application, faster data acquisition with broad data coverage (lateral and vertical), and lower costs. Data acquisition uses two configurations or electrode arrangement, namely sclumberger and wenner-schlumberger configurations. The number of trajectories for data acquisition uses one path with a total of 28 electrodes and the spacing between the electrodes is 20 meters. The data obtained in the form of data resistivity type of each underground layer and its depth will be further analyzed using AGISSAdmin software. The results are obtained in the form of a 2-dimensional (2D) cross-sectional value of underground layers laterally and vertically. The low resistivity value will be interpreted as a layer containing ground water, which was previously corrected against the geological and hydrological data of the area. From the cross section of the type resistors, values of 20 - 317 Ωm were obtained for the wenner and wenner-schlumberger arrangements. Selaru Village consists of two rocks unit, the first rock (≤ 120 Ohm.m) in the form of Tanjung Formation rocks, with large porosity and small permeability and groundwater potential in this unit is small (0 - 40 m depth). The second rock (≥ 120 Ohm.m) is Pre Tertiary, with very little porosity and permeability, except secondary porosity in rock fractures.
