Oneself prevention in using communication on the  internet of a student Rajamangala University of Technology Lanna Nan
Oneself prevention in using communication on the internet of a student Rajamangala University of Technology Lanna Nan

The aim of this research was to determine the effects of gender faculty and academic performance on the prevention of students to use to communicate on the Internet. Four hundred and thirty-three (male=225 and female=208) undergraduate students from 3 faculties including faculty of business administration and liberal arts science and agricultural technology and engineering in Rajamangala University of Technology Lanna Nan were used to fill in survey questionnaire. The results found that the gender had effected on the prevention oneself in the communication on the Internet. The male could prevent oneself more than female. In addition the student from engineering and science and agricultural technology could prevention oneself in the communication on the Internet more than faculty of business administration and liberal arts. However the academic performance had not affect on prevent oneself in the communication on the Internet. This study concluded that the prevention oneself in the communication on the Internet is affected by the gender and faculty but not the academic performance.

Community-based tourism management case study “palm paddy sea” community cultural way.  sa-ting phra district, songkhla province
Community-based tourism management case study “palm paddy sea” community cultural way. sa-ting phra district, songkhla province

The purpose of this research was to study community-based tourism management case study “Palm Paddy Sea” cultural way community Sa-Ting Phra district Songkhla province. The study was conducted by data collection interview people who involved in tourism management and tourists who traveled to the communities using questionnaire with 5 rating scales estimation. The data was analyzed according to the content and presented by descriptive analysis and tables. The study found that “Palm Paddy Sea” cultural way community has the potential to support eco-tourism. The tourism development of both natural and cultural resources within the communities encourage for being learning sources about community way and folk wisdom The community has participated in the development and wants to join in tourism management meetings with the Sub-district Administrative Organization. In addition the community requires that a community representative must have a chance to present ideas in a meeting in order to be developed in the same way. The guidelines for tourism development need to have cooperation from involved organizations in order to develop tourist attractions tourism facilities and promotions.

The development of a clear and fat separator of the jatropha oil
The development of a clear and fat separator of the jatropha oil

This research objectives are to develop a clear and fat separator of the Jatropha oil and to evaluate the performance. A machine consisted raw materials tank reactor clear and separated tank and control set. The reactor has diameter and the capacity of 50 cm and 90L and heated by electrical heater (3000 W). Flat blade agitator is driven by 0.25 HP of motor with 150 rpm and cooled by the water tube coil in diameter of 2.5 cm inside reactor tank. The clear and fat separated tank has a diameter and the capacity of 50 cm and 110L. From the evaluation of the machine performance raw jatropha oil (40 L) properties are viscosity and flash point of 42.66 cP and 240oC. After esterification process at temperature of 60oC at 150 rpm agitation for 60 min washed five times with water oil ratio is 1: 2 at a time for 20 min and then boiled to remove water for 60 min. The oil is reacted in tranesterification process at temperature of 60oC 150 rpm for 60 min and precipitated glycerol for 90 min and then washed and boiled to remove water. The products are glycerin (15 L) and ester oil (25 L) with the viscosity and flash point are 42.16 cP and 150oC and the color changed to clear yellow. The machine cost is 39690 THB. and payback period is 75 days

Teaching-learning models on acceptance and learning development in food processing of  agro-industry student, RMUTSV
Teaching-learning models on acceptance and learning development in food processing of agro-industry student, RMUTSV

Student satisfactory survey in Food Processing courses held at Rajamangala university of Technology Srivijaya was carried out. Twenty four undergraduate students in the program of Food Science and Technology were selected and evaluated the questions based on course content course material teaching techniques; lectures and practical part report and presentation and field trip.The satisfactory on the course content was found to be very high level. Teaching techniques were found to be no statistically significant (p<0.05). However students had the most preference toward the lectures giving by using Power Point Presentation as a teaching technique. On the other hand practical part of the course was found to be very useful appropriate in daily life and important skill for a professional food scientist. Notablyreport and presentation was very useful to improve English reading Thai editing and presentation skill. Field trip study was suggested to be significantly additional learning experience as well as course assignment presentation. In addition good relation between lectures and students had highly significant important for enhancing learning process.

The development of rotary dryer for paddy  using Hot Air recovery system
The development of rotary dryer for paddy using Hot Air recovery system

This research’s objectives were to develop an energy saving rotary dryer for paddy using hot air recovery system and to evaluate the energy using. Rotary dryer divided rotating cylinder made of 304 stainless steel 2 mm of thickness 39 cm and 200 cm of diameter and length. The inverter was used to control speed of gear motor of 0.5 HP and rotating speeds of 1-3 rpm. The inside of cylinder composed screw and capture flights. The cyclone system was used to dust separating from the system. The moisture trap contained silica gel the outlet hot air was reduced moisture and recovered using. The fiber glass insulator was applied for reducing energy loss. The heating box composed 3 set of 1600 W heaters and blower motor power was 0.5 HP. In the experiment the drying temperature was varied of 50 60 70 and 80oC and cylinder speed was varied of 1 2 and 3rpm (15.66 10.66 and 5.66min of drying time). The initial moisture content of 10 kg paddy was 29.7?0.6 %wb. The result show that the optimum conditions drying temperature and cylinder speed were 70-80oC and 1 rpm (15.66 min) and final moisture content was 9.2-11.8 %wb. From the save energy testing found that the reducing of SEC was 0.4-0.6 MJ/kg water per drying cycle. There for this developed dryer can save energy using
