The research studied the robust regression estimation-S on Tukey-Bisquare and Welsch weighting function. Due to the data contains outliers, we therefore used robust regression to handle outliers. The purpose is to find the best model between the Tukey Bisquare or Welsch. The mean square error (MSE) and adjusted is then used. The simulation data is a human development index (HDI) in Papua in 2021. The result showed that the robust regression model on the S-estimation between Tukey Bisquare and Welsch are similar (close). However, the adjusted weighting function Welsch is greater than the Tukey Bisquare, and the MSE of the Welsch is smaller than the Tukey Bisquare, so we recommended the robust S-estimation Welsch is a little better.

Least Square Method is one of methods for estimating of parameters of regression model. Model of least square methods is not valid if there are some disobeydiance in classical assumptions, for example, there are outliers. To resolve the problem, robust regression method is usually used. The method is used because it can detect the outliers and give stable results. In this research, data used is data for human development index of districts in Central Java from 2019 to 2020. Estimation for robust regression method chosen is estimation-M and estimation-s with Tukey Bisquare as a weight function. Criterions for choosing the best model are based on adjusted R-Squared value and mean square error (MSE). The result shows that robust regression model with estimation-M is a better model since it has adjusted R-Squared value tending to one and the least MSE.

In this research, PLS method is applied to analyze which factor are affect employee performance in PT. Kereta Api Indonesia (Persero) DAOP 5 Purwokerto based on variables that are research factors that is employee performance, work motivation, leadership, training, work enviroment and corporate culture through the indicator which are then analyzed. From analysis using a PLS method with 6 variables of research, it was found that R-square value work of motivation variables of 77,00% with good assessments defined by construct variable of leadership, training, work enviroment and corporate culture while another 23% is described by other variables outside this research. The value of R-square on employee performance variables of 66,00% with good enough assessment criteria described by the work of motivation, where as another 34% is described by other variables outside this research model.

An effort to develop village tourism potential is not a simple issue. This development requires careful planning and proper management. The purpose of this research is to formulate a synergy model that engages the village government and village consultative agency elements in the development of village tourism potential. This study takes Baturraden Sub-District, Banyumas Regency, as its research location. Baturraden Sub-District boasts a famous tourism destination, Baturraden Tourist Attraction, and 12 (twelve) villages with tourism potential in its surroundings. In this case, the village government (Pemdes) and Village Consultative Agency (BPD) play a vital role in building synergy to arrange a village tourism potential exploration policy. This legal research employs a qualitative approach, combined interview to collect the data, FGD, a document study, and observation. The research results find that BPD, which takes its role in village discussion, attempts to explore and develop village tourism potential by engaging all stakeholders.

Janggolan village is a village with limited locally generated revenue. In Sumpiuh sub-district there are 14 villages, 3 of which are the village of Janggolan. Village Fund Provision Policy in Law Number 6 Year 2014 on Villages affect on the performance of village apparatus and the quality of village community participation, while the Village Consultative Board (BPD) is expected to be an institution capable of playing role in village development. The problem is how the role of BPD in the implementation of Village Governance in the Janggolan village. The research was conducted by applying qualitative method with action research strategy. The results show that the Village Funds assisted the physical village development and work scheme but did not change the people attitude. BPD makes use of rembug warga (deliberation), selapanan (a traditional ceremony to commemorate a 35-day-old baby), and village meetings to accommodate aspirations and control the village. Yet they do not solve the village problems. The role of BPD in Janggolan village more focused on the absorption of people's aspirations. The internal constraints are low quality of members of BPD while the external constraints that BPD has not effectively performed. Keywords : deliberation, governance, societal participation.

Increasingly strong competition in intercollegiate and students who increasingly selective and knowledgeable require universities to continue to improve his ministry. Matter requires a knowledge of the conditions for this service, that has adapted to student expectations or not . This study aimed to determine the extent to which level the match between the expected service quality and perceived student at Department of Mathematics and Natural Sciences Unsoed and explain the influence of the five dimensions of service quality that is tangibles, reliability, responsiviness, assurance and empathy for student satisfaction and loyalty. Results of the study was assessment of the quality of student services at the Department of Mathematics and Natural Sciences Unsoed is perceived service quality is still below the expected service quality , perceived still not satisfactory. Five dimensions of service quality consisting of tangibles, reliability, responsiveness, assurance, and empathy, positive effect on student satisfaction. Satisfaction indirect influence on student loyalty and there is a direct influence of the five dimensions of service quality on loyalty through student satisfaction. Student loyalty translated in expressing positive things about the Department of Mathematics and Natural Sciences to others , recommending courses at the Department of Mathematics and Natural Sciences to the others, recruiting new employees from alumni, and ready to provide assistance if needed.

Tuberculosis prevention in Banyumas which still become problem is the owness of case finding of positive Tuberculosis victims. It is caused by lack of supporting aspect from community. For 2007 there are 4229 cases and 367 of them are active patients who take medical treatment. This research aim to for: a). to making a map of thematic which good for knowing pattern spreading of disease of TB in Banyumas, b). knowing factors having an effect on to spreading of disease of TB in Banyumas, and c). knowing subdividing pattern (regional clustering) pursuant to spreading of disease of TB in Banyumas. This research uses method of fuzzy set with approach of Geographical Information System.Results which are obtained from this research are: a) Tuberculosis event is significantly related to poverty. It is caused by low education level and occupation of Tuberculosis victim. b) Tuberculosis spreading is not related directly to population density, age, disease status of Tuberculosis victims and distance from medical facility. Spatial distribution pattern of Tuberculosis does not follow a certain pattern and c) Tuberculosis clustering tend to cluster at poor area in the city and spread follows the river flow.
