During the Covid19 pandemic, online learning platforms are solutions to sustain the English Language Teaching (ELT). It is an appropriate platforms option for lecturers to deliver the course materials amidst the covid19 outbreak. Some of the most frequently used platforms are Zoom and WhatsApp. The purpose of this study is to describe the EFL university students’ perceptions of the use of Zoom and WhatsApp in ELT. A virtual class in form of Zoom and WhatsApp was created to enable students to remotely attend the class and at the same time to keep in line with the covid19 health protocol. This study involved 53 students as respondents. The data were obtained through online-based questionnaire and were analyzed based on a mixed method approach by combining quantitative and qualitative method. The result revealed that the virtual class of ELT for EFL University students in form of Zoom and WhatsApp was considered positive by the learners. Although the availability and slow speed internet connection were being problems to use them in ELT, they were also rated effective and efficient in terms of time, place and expense. Moreover, learners agreed that those two online platforms can help them to improve language skills and to reduce shyness in virtual class interaction.

Coral reef restoration projects have been conducted worldwide to increase the viability of damaged coral reef ecosystems. Most failed to show significant results. A few have succeeded and gained international recognition for their great benefits to ecosystem services. This study evaluated reef restoration projects in North-west Bali from the perspective of the local community over the past 16 years. As community participation is a critical support system for coral reef restoration projects, the contributing factors which led to high community participation and positive perceptions are examined. Social surveys and statistical analysis were used to understand the correlations between community perception and participation. The findings showed a positive correlation between community perception and participation. The level of community participation also depended on how their work relates to coral reef ecosystems. They supported this project in many ways, from project planning to the religious ceremonies which they believe are fundamental to achieve a successful project. Several Balinese leaders became 'the bridge' between global science and local awareness. Without their leadership, this study argues that the project might not have achieved the significant local support that has restored both the environment and the tourism sector in North-West Bali.

Larasati RF, Suadi, Setyobudi E. 2018. Short Communication: Population dynamics of double-spined rock lobster (Panulirus penicillatus Olivier, 1791) in Southern Coast of Yogyakarta. Biodiversitas 19: 337-342. The southern coast of Yogyakarta, Indonesia, near to the Indian Ocean borders is a preferable habitat for lobster. Double-spined rock lobster (Panulirus penicillatus) is one of the prevalent species caught by fishermen. However the increased number of capture activities had an effect on the sustainability of global lobster fisheries. In order to sustain these fisheries resource, the preservation management of lobster should include wild stock assessments. Currently, the effect of fishing pressures on populations of P. penicillatus is limited. The objective of this research was to identify several factors affecting lobster population in terms of growth (carapace length (CL) and mass), recruitment, mortality rates, and exploitation rates in this species. Results showed that double-spined rock lobster had a longer size (CL) (45.2-55.1 mm) than that of females (55.2 mm-65.1 mm). While the growth rate (K) of males lobster is 0.85 year-¹ and its CL reached an asymptotic point at 125 mm (12 years old). Growth rate of females double-spined rock lobster was 0.55 year-¹ and its CL reached an asymptotic point at 125.5 mm (15 years old). The total estimation of mortality rates of double-spined rock lobster was 2.46, wherein 2.56 year-¹ for males and females, respectively. The estimated values of M were 1.08, 0.81 year-¹ for males and females, respectively while the respective values of F were 1.38 year-¹ and 1.75 year-¹ for males and females. The exploitation rate of males was 0.56 and females was 0.68. It has exceeded the optimal level (0.5) and reached overfishing value. Based on these results, it suggest that the time management of fishing activities such as by several approaches including the restricted time of fishing activity in spawning and recruitment season, the management of catching effort by the development of environment-friendly fishing gear, and the development of the lobster hatchery to reproduce and maintain their population naturally.

The aims of this research were to know the history and development of fisheries activity and its contribution to coastal community welfare at South Coast of Yogyakarta Special Territory Province. To examine these issues the research was conducted by combined survey and descriptive analytic methods. Fisheries in area could be categorized as new activity and historically community does not have a high dependency on marine capture fisheries. Fishers were  farmers who become fisherman due to several reasons such as limitation of land and lack of other job opportunity. Since the activity began in the end of 1970’s at Baron, marine capture fisheries have altered income sources, improve community houses, and attracted young people as well as provide productivity activity for rural women. In the recent time, marine capture fishery has dispersed to all of Yogyakarta South Coastal area at 19 fish-landing places with vary intensity of resources exploitation. Marine capture fisheries are still limited in the coastal zone. Although CPUE tend to increase, the activity should be extended to province management zone and ZEEI. The integrated policy and management are needed to solve these problems and to avoid the tragedy of the commons.
