Abstract

The sandy beach where turtles lay their eggs is a natural incubator and has a suitable environment for the development of turtle embryos. Microclimate suitable for incubation of turtle eggs arises from interactions between physical characters, beach compilers, the local environment and eggs in the nest. One of the locations where sea turtles land and lay eggs in West Nusa Tenggara Province is on the beach of Lunyuk, Sumbawa Regency. Receiving sea turtles is a protected endangered species, it is necessary to carry out conservation activities to protect and save sea turtles. To support efforts to support, it is necessary to support locations where turtles lay their eggs. Like discussing research on landing sites and turtle nesting sites. The purpose of this study was to analyze the level of suitability of habitat characteristics for turtle nesting in the Lunyuk beach area. The research method uses the survey method. Survey activities include field observations and collecting primary data. Data analysis was performed using the weighting and scoring method. Based on observations it can be seen, the slope of the beach which is the location of spawning is 6.54 - 11.1%, substrate temperature 27 ° C - 32 ° C, humidity substrate 25% - 40%. While the percentage of vegetation is 40% - 57.1%. From the station visit, stations 1 and 2 are quite suitable, while stations 3, 4 and 5 are categorized according to the location of turtle nesting.

Abstract

The COVID-19 pandemic is a problem faced by almost all countries in the world including Indonesia which has implications for the fisheries sector. Fisheries sector players including vulnerable groups affected by COVID-19. This study aim is to analyze the application of health regulation that contain understanding and application of health regulations on fisheries and the impact of COVID-19 on commodity prices and fishing activities. The method used in this study is an online survey through a questionnaire using Google forms and in-depth interviews through the telephone network involving 45 respondents of fishermen. The survey results show that 93% of fishermen knew enough about the COVID-19 pandemic, 84% were quite worried, 7% were very worried and 9% had no effect. Most fishermen have implemented health protocol efforts including activities to wear masks, avoid shaking hands and washing hands with soap. Pandemic has an impact on the decline in fishery commodity prices by 10%. The impact of the pandemic on fishing activities is the delays in the delivery of commodity products, the decrease in the number of fishing, the decrease in the number of catches and demand for catches and the decrease in fishermen's income.

Abstract

This study aims to analyze the water parameters that support fresh fish cultivation in the Batu Bulan dam, Maman Village, Moyo Hulu District. The study used a survey method at three observation locations, inlet, center, and outlet of the dam on water quality, including temperature, brightness, substrate, pH, dissolved oxygen (DO), turbidity, salinity, ammonia, Phosphate, and depth. The results showed that the inlet temperature ranges from 29,32oC, in the middle ranges from 29,91oC, and the outlet is 29.11oC. The average brightness at the inlet is 41.04 cm, the middle is 48.20 cm, and the outlet is 34.16 cm. The substrate at the inlet and in the middle is muddy while the outlet is sandy. The pH average in inlet is 6,33, in the middle is 6,58, and outlet 6,53.  Dissolved oxygen (DO) in the inlet range is 5.34 mg/l, in the middle is 5.51 mg/l, and in an outlet, it is 5.85 mg/l. Turbidity in the inlet range is 2,44 NTU, in the middle 2,67 NTU, and an outlet is 3,26 NTU. Salinity in all locations is 0 ppt. Ammonia in the inlet range is 1,01 mg/l, in the middle 0,69 mg/l and outlet is 1,1 mg/l. The average Phosphate at the inlet is one mg/l, in the middle and outlet is 0 mg/l. The status of the water eligibility for aquaculture is that the inlet and middle of the dam are suitable for cultivation, while those at the outlet are less feasible.

Abstract

The COVID-19 pandemic necessitated a rapid shift from traditional face-to-face learning to online modalities, including student evaluations. This study delves into the disparity between the perceived effectiveness of online learning evaluations and actual student experiences during the pandemic, drawing insights from existing data that highlighted student disagreement regarding the ability of online evaluations to measure material mastery, foster creativity, and enhance thinking skills. While previous research often focuses on quantitative correlations, this qualitative-dominant analysis aims to explore the underlying reasons for student dissatisfaction. It investigates how factors such as technical issues, time pressure, and the design of online assessment tools contribute to these perceptions. By understanding the nuances of student perspectives, this paper seeks to provide valuable insights for educators and policymakers in designing more effective, equitable, and student-centric online evaluation strategies that move beyond mere digital replication of traditional methods.

Abstract

The COVID-19 pandemic necessitated an abrupt shift to online learning, including its evaluation, presenting both challenges and opportunities for innovation in higher education. This study, originally conducted at Universitas Samawa, explored lecturers' and students' profiles and perceptions of online learning evaluations during the pandemic. Findings revealed that WhatsApp was the most dominant platform (76.7%) due to its ease of use, practicality, and accessibility. However, significant obstacles emerged, primarily unstable internet connectivity, especially for students in rural areas, and suboptimal understanding of online learning materials often due to lecturers merely sharing content without in-depth explanations. While online evaluations were perceived as more objective and capable of fostering creativity and critical thinking, concerns regarding academic integrity due to insufficient supervision were also noted. This paper analyzes these identified constraints, juxtaposing them with potential avenues for innovation in online evaluation practices. It argues that addressing connectivity gaps, enhancing pedagogical design for online content delivery, and implementing robust integrity measures are crucial for developing a more effective, equitable, and sustainable online evaluation system in the post-pandemic era.
