Abstract

Green leafhopper (GLH), Nephotettix virescens, is the most efficient vector of rice tungro virus disease. The disease is endemic in some provinces of Indonesia and commonly con-trolled using resistant varieties. Resistance of rice varieties to tungro could be classified into resistance to a virus and a vector. The history of GLH resistant varieties adoption affected the GLH adaptation in an area. The study was conducted in the period of 2009-2011 to evaluate the resistance status of five GLH resistant rice variety groups (T0-T4) using survival and transmission test. The GLH populations were collected from 15 tungro endemic provinces in Indonesia. The GLH was then reared in the greenhouse before used for the test. The degree of resistance to tungro viruses was calculated by adding the value of survival (weight x score of survival rate) and virus transmission rate (weight x score of transmission rate). The weights for survival and transmission rate were set to 40 and 60, respectively. The results showed that the rank of resistant variety groups in decreasing order of resistance were T4, T1, T2 and T3. Five variations in GLH transmission efficiency were identified, i.e. 170, 070, 050, 030 and 010. GLH populations from Bali and West Nusa Tenggara were the most efficient vector for rice tungro virus. We concluded that there were diversities in the degree of resistance among GLH resistant varieties. Variation in virus transmission efficiency (biotype) among GLH populations collected from various tungro endemic areas closely related to the history of adoption of rice varieties.

Abstract

This study aims to develop the character of early childhood by using cultural malay-based traditional games. The children's world is synonymous with the playing world so that learning is more easily absorbed by children through play. Traditional games are very important to be introduced so children can find out games that have been around for generations. Children are introduced to traditional games that elevate Malay culture. The Malay culture is a characteristic of the Lancang Kuning earth, so that it became the Riau Vision and Mission in building its territory in reference to Malay Culture. In addition, through Malay culture children are educated in character building. The character of children is shaped according to Malay culture which is full of morality and religion. Child character development is very important to be formed early because character is permanent and inherent in children to adulthood. This study belongs to the category of descriptive research which describes the data relating to the formulation of the problems examined in this study. Data collection used in this study was carried out by total sampling technique. This research uses a Likert scale, namely from the results of observations and interviews. Then, the data analysis technique used is descriptive technique.

Abstract

Research suggests that child independence is more popular in countries with greater wealth and a higher percentage of the educated population. Various research implications expect children's independence and compliance to increase over time in developing countries. This study aims to describe the independence of early childhood who comes from low-income families or at low socioeconomic environment. Using quantitative descriptive, data collection techniques are carried out through a questionnaire. The study population was 30 respondents from the ECE institution who were included in the list of low-income families in 2018, using an area sampling technique. Overall, the teacher stated that all indicators of dependence on children from low-income families had reached the high category, which was 75%. The implication of further research is that aspects of independence in physical abilities, self-confidence, responsibility, discipline, sociability, sharing, and independence in terms of emotional control in early childhood can develop better in a low socio-economic environment.
