Rearing of Local Earthworms in The Mixed Media of Bagasse and Fish Waste

This study aims to determine the preference of earthworms to a media, their population growth in the media, and their ability to produce vermicompost. This study was designed with a completely randomized design consisted of three (3) treatments and each treatment consisted of 7 replications. The treatments in this study were 3 species of local earthworms (Pheretima javanica, Pheretima asiatica, and Pontoscolex corethrurus). The rearing media used was the mixture of bagasse and fish waste. The parameters studied were the time needed by the earthworms to enter the media, the earthworms population growth rate, and the time needed by the earthworms in producing vermicompost. The results showed the three species tested could be lived on mixed media of bagasse and fish waste. The worm's preference to the media was determined based on the time of earthworms entering media. The fastest was Pheretima javanica (0.23 minutes), followed by Pheretima asiatica (3.09 minutes) and Pontoscolex corethrurus (6.94 minutes) (p<0.05). The population growth rate between Pheretima javanica (5.85) and Pheretima asiatica (5.71) was not significantly different, but both significantly higher than Pontoscolex corethrurus (0.29 individual/month). The time for vermicompost formation in Pheretima javanica (6 weeks) and Pheretima asiatica (6 weeks) was not significantly different, but they were significantly lower from the time for vermicompost formation in Pontoscolex corethrurus (8 weeks)

Enhancing oral communication skills using mobile phones among undergraduate english language learners in Malaysia

The study introduced the use of mobile phones in an English language learning course to second-language learners studying at a higher-education institution in Malaysia. Mobile phones have multifunctional capabilities that can be used anytime and anywhere at the convenience of the learners; therefore, the study aimed to investigate the possibility of using mobile phones as tools to improve the oral interaction skills of the learners. The study explored the basic functions built into mobile phones relevant for an oral communication skills course. A class of 50 learners was assigned as the treatment group and another class of 26 learners as the no treatment group. The treatment group was introduced to the audio recording devices in mobile phones and encouraged to practice the tasks assigned before the evaluation. This study adopted a quantitative research design, and the tools employed were a survey questionnaire and the course assessments. Data in the classroom were collected over a 10-week period. The findings demonstrated an increase in the performance of the learners at the end of the semester; nevertheless, the results must be interpreted with caution as use of mobile phones only started in week 5 of the 10-week semester which may not have given learners sufficient time to master the skills required to use them optimally for language learning.
