Caravan Awnings: a Geometrical Problem

Two questions regardingthe design of caravan awnings were posed by a company.The company wishes to produce awnings with a pretty appearance. When an awning is attached to a caravan, some wrinkles could appear. We developed some methods to avoid the wrinkles. The problem is restricted to awnings which are made from one piece of cloth

Pemodelan Tingkat Penghunian Kamar Hotel di Kendari dengan Transformasi Wavelet Kontinu dan Partial Least Squares

Multicollinearity and outliers are the common problems when estimating regression model. Multicollinearitiy occurs when there are high correlations among predictor variables, leading to difficulties in separating the effects of each independent variable on the response variable. While, if outliers are present in the data to be analyzed, then the assumption of normality in the regression will be violated and the results of the analysis may be incorrect or misleading. Both of these cases occurred in the data on room occupancy rate of hotels in Kendari. The purpose of this study is to find a model for the data that is free of multicollinearity and outliers and to determine the factors that affect the level of room occupancy hotels in Kendari. The method used is Continuous Wavelet Transformation and Partial Least Squares. The result of this research is a regression model that is free of multicollinearity and a pattern of data that resolved the present of outliers

The Occupancy Rate Modeling of Kendari Hotel Room Using Mexican Hat Transformation and Partial Least Squares

Partial Least Squares (PLS) method was developed in 1960 by Herman Wold. The method particularly suits with construct a regression model when the number of independent variables is many and highly collinear. The PLS can be combined with other methods, one of which is a Continuous Wavelet Transformation (CWT). By considering that the presence of outliers can lead to a less reliable model, and this kind of transformation may be required at a stage of pre-processing, the data is free of noise or outliers. Based on the previous study, Kendari hotel room occupancy rate was affected by the outlier, and it had a low value of R2. Therefore, this research aimed to obtain a good model by combining the PLS method and CWT transformation using the Mexican Hats them other wavelet of CWT. The research concludes that merging the PLS and the Mexican Hat transformation has resulted in a better model compared to the model that combined the PLS and the Haar wavelet transformation as shown in the previous study. The research shows that by changing the mother of the wavelet, the value of R2 can be improved significantly. The result provides information on how to increase the value of R2. The other advantage is the information for hotel managements to notice the age of the hotel, the maximum rates, the facilities, and the number of rooms to increase the number of visitors

Capillary-Gravity Waves on Depth-Dependent Currents: Consequences for the Wave Resistance

We study theoretically the capillary-gravity waves created at the water-air interface by a small two-dimensional perturbation when a depth-dependent current is initially present in the fluid. Assuming linear wave theory, we derive a general expression of the wave resistance experienced by the perturbation as a function of the current profile in the case of an inviscid fluid. We then analyze and discuss in details the behavior of the wave resistance in the particular case of a linear current, a valid approximation for some wind generated currents.Comment: Submitted to EP

Implementasi Program Nasional Pemberdayaan Masyarakat Mandiri Perdesaan Di Desa Kebumen, Kecamatan Pringsurat, Kabupaten Temanggung

PNPM-MP is one of the mechanisms of community empowerment program in an effort to accelerate poverty reduction and expansion of employment opportunities inrural areas. Guidelines for the implementation of PNPM-MP contained in the Decree of the Coordinating Minister for People's Welfare No. 25 of 2007. PNPM-MP implementation in various places showed varying results. Pringsurat District Temanggung Regency, is one of the districts that implement the PNPM Mandiri since the beginning of the name of the PPK in 2003. In this district, the biggest beneficiary in 2012 is Kebumen Village.Implementation of PNPM-MP at Kebumen Village has been good since it follows the stages of Directive Technical Operations. Constraints faced which are deteriorationof physical activities and clogged installment loans are now almost resolved. Planning should take into consideration in the implemention based on community activities, siteconditions and seasons. At the time of eligibility verification, character of the people who apply should be considered, as well as their ability and discipline to pay

Pengembangan Kapasitas Kelembagaan Pada Program Gerdu Kempling Di Kecamatan Pedurungan

Gerdu Kempling is a poverty reduction program in the Semarang city. Various problems such as lack of assistance on an ongoing basis to the recipient, not arranged organizational structure that handles the Gerdu Kempling program clearly and weak supervision in the implementation of the Gerdu Kempling program into the background in this study. Necessary institutional capacity building to enhance the ability of people, organizations, or systems in achieving the stated goals effectively and efficiently with the look of the variables of leadership, doctrine, programs, resources, and internal structure. This study aims to analyze the institutional of capacity building to program Gerdu Kempling in the Pedurungan district and to investigate the factors that support the institutional of capacity building. This research uses descriptive qualitative method. The results showed that the institutional of capacity building to Gerdu Kempling program in the Pedurungan district not run at max. The availability of resources is not accompanied by maximum utilization, sustainable professionals not accompany the recipient, the procedure does not run as expected, none specifically organizational structure to handle Gerdu Kempling program. Institutional capacity building will work well if done well supporting factors, which include participation, innovation, access to information, and accountability. Based on these conclusions, the researchers recommend the Pedurungan district organization can optimally enhance its ability to be a coordinator, facilitator, and implementing monitoring and evaluation, so as to achieve the set objectives effectively and efficiently
