Abstract
The health center is the first level public health service center that is run by the Indonesian government. Organizing quality health center services of health center is the hope and satisfaction of every patient. The dimensions of patient satisfaction vary greatly and the scope is very wide. Patient satisfaction can be used as an indicator of quality and service performance of health center. The purpose of this study was to measure the performance of health center services in order to determine the level of patient satisfaction and grouping the Patient Satisfaction Index. With the knowledge of the dimensions of performance and quality of health services provided by the health center, it will facilitate the government in carrying out the function of guidance and control of the health center. This study uses a Machine Learning technology approach with clustering techniques, by grouping the Patient Satisfaction Index with K-Means (Hard Clustering) and Fuzzy C-Mean (Soft Clustering) methods. Based on the subsets produced, clustering techniques can be divided into 2 methods, namely hard clustering techniques and soft clustering techniques. The K-Mean method is widely used in clustering techniques. K-Mean has advantages in computational speed and relatively easy process stages. While the Fuzzy C-Means method has advantages in terms of flexibility in determining clusters so that there is little possibility of converging failure. The experimental results of the Patient Satisfaction Index show that the K-Means method provides better performance with a value of 96% compared to the Fuzzy C-Means method with a value of 76%.

Abstract
This paper discusses how to predict students’ positive attitudes toward mathematics using mathematical anxiety and self-efficacy data. The dimension is rooted from many researchers concluding that mathematical anxiety, self-efficacy and positive attitudes towards mathematics have relationship each other. We also modelize form to predict students’ attitudes using a fuzzy model. 312 data for training and 68 data for testing models used is from 380 pairs of anxiety, self-efficacy, and positive attitudes data. Further analysis showed that the first fuzzy model within 13 fuzzy sets produces 61 fuzzy rule base and the fuzzy model with 16 fuzzy sets produces 82 fuzzy rule base. Every model is carried out by using MAPE for training and testing the data. The first fuzzy model, the second fuzzy model and regression model with training data successively produced MAPE of 7.35%, 7.06%, and 7.98%. Furthermore, using the testing data of the three models successively produced MAPE values of 7.43%, 7.16%, and 7.45%. Based on the MAPE, it can be concluded that the fuzzy model is better than the regression, and the fuzzy models with 16 fuzzy sets and 82 rules are the best models that can be employed to predict students’ positive attitudes toward mathematics.

Boreal tree-rings are influenced by temperature up to two years prior to their formation: a trade-off between growth and reproduction?
Authors: Tumajer Jan , Lehejček Jiří 
Published: October 2019

Abstract
Large spatial and between-tree variability has recently been observed in the response of boreal forests to ongoing climate change, spanning from growth stimulation by increasing temperatures to drought limitation. To predict future responses of boreal forests, it is necessary to disentangle the drivers modulating the temperature-growth interaction. To address this issue, we established two inventory plots (at a treeline and closed-canopy forest) and assembled site chronologies in Picea glauca stands at the transition between boreal forest and tundra in Northern Quebec, Canada. In addition to site chronologies, we established a set of chronologies containing, for each year, exclusive subsets of tree-rings with specific cambial age (young/old), tree dimensions (small/large) and tree social status (dominant/suppressed). All chronologies were correlated with climatic data to identify the course of climatic conditions driving variability in tree-ring widths. Our results show that the growth of P. glauca correlates significantly with summer temperature in tree-ring formation years and during up to two prior summers. Tree-ring width is positively influenced by summer temperatures in tree-ring formation year and two years prior to tree-ring formation. In addition, climate-growth correlations indicate a negative effect of summer temperature one year before tree-ring formation at the closed-canopy forest site. The pattern of climate-growth correlations is tightly synchronized with previously published patterns of climate-reproduction correlations of P. glauca, suggesting a growth-reproduction trade-off as a possible factor modulating the response of boreal forests to summer temperatures. Climatic signal does not differ between pairs of chronologies based on subsets of cambial ages, stem dimensions or tree competition status at the treeline site. However, the response to summer temperatures one year before tree-ring formation is significant only in mature (old, large and dominant) individuals at the closed-canopy site. The inverse pattern of temperature-growth correlations during a sequence of three years challenges predictions of how boreal forests respond to climate change.

Published: October 2019

Abstract
Pasundan cattle is a local livestock that has lived and well adapted in West Java. In 2015, the population declined by 20.96% caused by the high selling prices and changes in land functions. The impact of declining of the population can causes genetic degradation indirectly. One of the efforts to increase the population is selection of cattle based on luteinizing hormone receptor gene polymorphism that can used as molecular selection for reproductive traits. Thirty seven heads of Pasundan cattle with artificial insemination calving records was used in this study. The exon 11 of LHR gene was amplified and subsequently analysed by sequencing method. The sequencing result were found three genotypes of CC, CT and TT in SNP g.1337C>T. The frequency of T allele (0.527) shows more dominant over C allele (0.473). The chi square test showed that Pasundan cattle were in Hardy-Weinberg equilibrium. The heterozygosity value of Ho (0.513) indicating that the heterozygosity value of the LHR gene belongs to high category (>50%). The high genetic diversity of the Pasundan cattle population indicates that there has not been selection program yet. The results of this study can be used as a reference to continue the selection program improving genetic quality in the reproductive traits of Pasundan cattle.

Authors: Setiawan R , Priyadarshana C , Tajima A , Ishikawa N , Asano A 
Published: October 2019

AbstractCalcium ions play important roles in several cellular processes including signalling pathway, membrane fusion and cell adhesion. In sperm, it is known that intracellular calcium concentration ([Ca2+]i) regulates acrosome exocytosis and flagellar motility. [Ca2+]i is generally regulated by influx and efflux of calcium ion. Plasma membrane calcium ATPase (PMCA) pumps the [Ca2+]i excess, providing a fine-tuning of [Ca2+]i concentration for sperm functions. To date, information related PMCA family in chicken sperm is still not documented yet. Therefore, this study was subjected to characterize expression and localization of PMCA family in chicken sperm. In this study, we selected PMCA2 and PMCA4 as representative to a specific tissue and a housekeeping isoform, respectively. Immunohistochemistry of PMCA2 and PMCA4 in chicken testis showed that both transmembrane proteins are expressed at the edge adluminal of the seminiferous tubule, indicating that these proteins are present in morphologically matured sperm that completed spermatogenesis. This was confirmed by immunocytochemistry, showing that PMCA2 and PMCA4 are highly enriched in the midpiece of chicken sperm. Furthermore, sub-cellular fractionation, combined with western blotting, showed that both isoforms are exclusively found in the membrane fraction of the sperm, together suggesting both PMCA are localized to the plasma membrane overlaying midpiece.

Published: October 2019

Abstract
The Cisangkuy sub-watershed area, West Java is mostly up land farming. In the dry season the region often experiences drought. Efforts to anticipate regional drought can be done by calculating the balance of water availability of the region. One of the most important water balance calculation parameters is evapotranspiration. Direct evapotranspiration measurements in the field represent actual circumstances, but for large areas require large and long-term costs. One way to get regional evapotranspiration data is by reducing evapotranspiration information from remote sensing data. LANDSAT 8 OLI / TIRS satellite imagery is one of the resource satellites commonly used in agriculture. This study aims to determine the estimated value of evapotranspiration in the sub area of Cisangkuy watershed using LANDSAT 8 OLI / TIRS satellite imagery. The method used in this research is the energy balance model with descriptive analysis. The results showed that the highest value of evapotranspiration on August 17 in Cisangkuy Sub-Basin area in mixed forest was 4,190 mm / day. The results of data reliability analysis using root mean square (RMS) error indicate that satellite image can be used to identify evapotranspiration in Cisangkuy sub watershed with RMS error value of 1.124. The RMS value is still smaller than the average evapotranspiration field measurement difference, so it can be said that the evapotranspiration estimation is accurate.

Abstract
Fluctuations in rice production due to conversion of paddy field to other various land use defected the rice production in Indonesia, and in turn it may endanger the food security. Efforts to utilize hydroponics as a technology of vegetable production in limited land availability has developed. However, the practice of hydroponics in rice plants is still limited due to the availability of special nutrient. This study aims to determine the benefits of silicate rice husk extract on the growth of rice hydroponics. The research design used was complete randomized block design. The observed growth parameters are : plant height, electrical conductivity of nutrients and pH. The observed data were analyzed using variance analysis. If the results of variance analysis are significant, the analysis will be proceed with Duncan multiple range test. The results showed that application of rice husk silica extract of 20 ml/L through leaves gave the same response with sodium silicate (Na2O3Si) application through nutrient solution, but had significant effect on the change of electrical conductivity value and pH of nutrient solution. The results showed that silicates derived from organic materials can replace the role of silicates derived from inorganic materials on paddy hydroponic.
