Betta fish (Betta splendens) are freshwater ornamental fish that is very popular because it’s beautiful colors and unique behavior. This study aims to determine the growth measuring weight and length as well as the survival rate of betta fish seeds by providing different types of food that was conducted in door at Tulungagung, East Java, Indonesia. The study was experimentally designed with completely randomized design consisting of 3 treatments and 4 replications. The treatments A was fed with Tubifex sp., treatment B with artificial food (pellets), and treatment C was consisted of a combination of Tubifex sp., and artificial food. The test fish were 30 days old with a stocking density of 5/plastic bucket, where feeding was done ad-libitum. The study was conducted for 42 days. The parameters measured in this study were the growth in absolute weight and absolute length and its survival rate. Observations were analyzed using One Way Analysis of Variance (ANOVA) and further tests were carried out using the Duncan test. The results show that different feeding strategies had a significant effect on the growth of absolute weight and absolute length, and had no significant effect on the survival rate of betta fish. Water quality parameters measured include an average temperature was valued at 25.01oC-25.87oC, while the average pH was 8.42-8.47, and average dissolved oxygen (DO) was 4.13-4.17 mg/L.

Seaweed is one of Indonesia's fishery commodities with great potential to be cultivated, the condition of seaweed produced in Indonesia is not optimal yet. This can be seen from the low productivity of seaweed in Indonesia which is caused by the low growth rate. The growth rate of seaweed can be supported by proper planting techniques and cultivation methods. Seaweed farmers generally use planting techniques and traditional cultivation methods called the monoculture system, which is planting one type of plant in an area. As the cultivation systems developed, a new cultivation system was found that supports increased growth of seaweed, namely the co-cultivation. This system is sustainable and environmentally friendly which combines species from various trophic in one system. This research was conducted for 6 weeks from December 2019 to January 2020 in the coastal area of Pandawa Beach, Bali. The data was analysed in Completely Randomized design with three treatments and three replications. The monoculture cultivation system which contain 100 gr of seaweed in a bag was treated as control and co-culture systems were added with 10 and 30 individuals of abalones. The results showed that the growth rate pattern as a measure of weight increased during the time of study. The weight of seaweed was highest in co-cultured treatment with 10 individual abalones. The highest specific growth rate of seaweed occurred in the co-culture system up to 4%/day compared to the monoculture cultivation system only 3.4%/day.

The research was conducted in Dreamland beach, Pecatu Village, Bali. The purpose of this research is to identify the potential and the tourism suitability index of Dreamland beach. The research was carried out from the start of January to the end of February 2021. The method used for this research is the descriptive quantitative method. Furthermore, the researcher uses the purposive sampling method to group the location into three location points. There are three points measured in the tourism suitability index, including depth, type of beach, the width of the beach, the base material of the water, slope of the beach, current velocity, brightness, beach land cover, dangerous species, and availability of freshwater. The research shows Dreamland has various potentials such as white sand, big waves, and moderate sloping cliff which enables visitors to enjoy the sunset. As a tourist destination, Dreamland is equipped with several facilities including restaurants, toilets, and kiosks. Moreover, visitors can rent umbrellas and surfing boards. Additionally, for safety purposes, there will be a lifeguard on duty. Access to Dreamland is easy, it has two parking spots. Parking spot 1 is designated for motorcycles, whereas parking spot 2 is designated for cars and buses. Based on this research, Dreamland achieved a good Tourism suitability index at 2.51 at locations 1 and 2.59 at locations 2 and 3. The parameters which act as the limiting factors are the current velocity and brightness. High-velocity current results in the mixture of sedimentation and seawater which leads to murky water, thus low visibility rate.

Sun Bear (Helarctos malayanus) is found in Indonesia such as in Sumatra and Kalimantan. Helarctos malayanus is the smallest bear in the world and listed as vulnerable animal. Baloo is a sun bear that is rescued and raised at Bali Animal Rescue Centre located in Tabanan Bali. Before it will be released to the natural habitat, it is important to understand its behaviour, so it will be survived in their natural habitat. This study aimed to investigate the daily activity of sun bear rais at Bali Animal Rescue Centre. Research has been conducted at Bali Animal Rescue Centre from 2nd – 26th January 2019. Observation o daily activities of sun bear was conducted from 08.00 – 16.00 local time. It has been found that most of daily time was spent on grooming (35%), followed by feeding/eating (27%), moving (26%), and stationary (24%). Baloo has hardly found vocalized or defacate/urinate. Baloo was resting around 11.00 am and active feeding/eating along the day as well as moving. She moved a lot at 08.00 am, as she was provisioned by the carer, less moving in the middle of the day (12.00 am) and before resting at 17.00 pm. The variation of time spent on the daily activities of the sun bear at the rescue center can be used as reference before she will be release to its natural habitat.
