Abstract

A connected graph G is primitive provided there exists a positive integer k such that for each pair of vertices u and v in G there is a walk of length k connecting u and v. The smallest of such positive integer k is the exponent of G. A primitive graph is said to be odd primitive graph if it has an odd exponent. It is known that if G is an odd primitive graph then G contains two disjoint odd cycles. This paper discusses exponents of a class of primitivegraphs containing of exactly two disjoint odd cycles. For such graphs we characterize the odd and even primitive graphs.

Abstract

This study examines the fresh fruit bunch (FFB) yield and the effect of fruit storage on the quality of palm oil in Bangun Bandar Estate, Dolok Masihul, North Sumatra, with special reference to the physicochemical parameters. The quality of palm oil is mostly determined by the color, free fatty acids (FFAs), moisture, impurities, carotene content, and deterioration of bleachability index (DOBI). The palm fruits were stored in a refrigerator for 0, 7, 14, 21, and 28 days after harvesting before analyzing their carotenoid content, DOBI, FFAs, moisture, and impurities. The results showed that the potency of the crude palm oil (CPO) types, dura, pisifera, and tenera, were 23.5, 26.2, and 23.6%, respectively. The carotenoid content and DOBI of the palm oil types, dura, pisifera, and tenera, were decreased significantly by lengthy storage of the fruit. By contrast, lengthy storage of the fruit significantly increased the FFA, moisture, and impurity contents of these palm oil types, indicating that this reduced the quality of the palm oil. Oil processed from FFB has excellent quality with a high carotene content and DOBI, and a low concentration of FFA, moisture, and impurities. The present study contributes to palm oil stability and nutritional value.

Abstract

This study aimed to analyze the effect of leadership functions, work environment, and work motivation on personnel performance at the police station Pasaman Barat. Type of research is causative. The study population was all personnel at the police station Pasaman Barat. Sampling was based on stratified random sampling. Analysis of data used path analysis and hypothesis testing using the F test and t test. The results showed that: (1) The function of leadership a significant effect on work environment, (2) The function of leadership and work environment have a significant effect on work motivation, (3) The function of leadership, work environment, and work motivation have a significant effect on performance. (4) The function of leadership have a significant effect on performance through work environment, (5) The function of leadership have a significant effect on performance through motivation, and (6) work environment significant effect on performance through work motivation. This suggests that the function of leadership, work environment, and work motivation has a significant effect, directly or indirectly, to the performance of personnel at the police station Pasaman Barat. Keywords: leadership functions, work environment, work motivation, performance
