    Abstract: Dinoflagellates are one of the phytoplankton groups that an important role as primary producers in waters. However, in very abundant conditions (blooming) it can be dangerous for ecosystems and aquatic biota. This study aims to determine the composition and abundance of harmful dinoflagellates and environmental factors that influence the presence of dinoflagellates in coastal area of Mayangan and Binor, Probolinggo Regency, East Java. The method used in this study is a survey method by determining the sample point by purposive sampling. The research was conducted in March 2022. The result showed that the abundance of dinoflagellates in Mayangan waters 255 – 1511 cells/mL consisting of 10 genera namely Alexandrium, Ceratium, Dinophysis, Gambierdiscus, Glenodinium, Gymnodinium, Ostreopsis, Peridinium, Phyrodinium, and Prorocentrum . The abundance of dinoflagellates in Binor waters 716 – 2536 cells/mL consisting of 10 genera namely Alexandrium, Amphydinium, Bysmatrum, Cochlodinium, Gambierdiscus, Glenodinium, Gymnodinium, Peridinium, Protoperidinium , and Scrippsiella . The highest genus in Mayangan waters Ceratium 18% and Binor waters Protoperidinium 21%. The abundance of dinoflagellates in the Mayangan and Binor waters has no potential for blooming, but the presence of the dinoflagellate genus in the waters can still endanger coastal ecosystems because it can produce toxins. The presence of dinoflagellates is influenced by environmental factors such as salinity, nitrate, and phosphate.

    Abstract: The Lekok Coast is part of Pasuruan Regency which has various community activities. The condition of the waters is influenced by natural and anthropogenic factors which receive a lot of input loads from the mainland. These input load can come from human activities such as aquaculture, industry and domestic waste that enters through rivers and then empties into the coasts. These conditions can affect the fertility of eutrophic, mesotropic or oligotropic waters. This study aims to determine the conditions of the waters based on the abundance of phytoplankton and the physical and chemical parameters of the waters to see the fertility status of the waters. The descriptive method is the method used in this study and the determination of the sampling point uses the purposive sampling method, the research was conducted in April – May 2019. Based on the results of the abundance of phytoplankton in the coastal waters of Lekok, it is classified into waters that have oligotrophic fertility levels. The results of observations and measurements of physical and chemical parameters in the coastal waters of Lekok showed that several parameters that support the growth of phytoplankton are less than optimal, such as temperature, brightness and nitrogen elements.

    Abstract: Ocean waves are one of the renewable energy potentials for an archipelago country like Indonesia. The development of Wave Energy Converter presented in the research carried out is a system that uses a pontoon with a pendulum for energy extraction, which is called the Pendulum System Wave Power Plant (PLTG-SB). The shape of the pontoon uses a trimaran model with a cylindrical shape as the main body and support. The simulation of the response of the pontoon with multi pendulums shows the maximum RAO pitch value of 1.15° / cm in the 6 second wave period and the response to the change in deviation is the maximum value in the 6 second wave period with a deviation of 198.07°. The variation in the length of the pendulum arm gave the largest deviation value of 106.7 cm, while in the variation of the number of pendulums the largest deviation occurred on the pontoon with the number of pendulums n = 2.

    Abstract: The essential oils of Lavandula angustifolia (lavender) and Citrus aurantiifolia (lime), have been used in several applications such as food industry, pharmacy, and cosmetics industries. In this report, we examined the biological activities of lavender and lime essential oils through several studies using β-carotene bleaching assay, 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, antidiabetic assay, antibacterial assay, and also measure its total phenolic content (TPC). The functional group of lavender and lime was studied using Fourier transform infrared spectroscopy (FTIR), while the volatile compound was evaluated using Gas chromatography–mass spectrometry (GC-MS) analysis. The result showed that in DPPH assay, both of lavender and lime essentials oil have low activity with IC 50 of 1966.02 ppm and 4303.42 ppm, respectively, while in beta-carotene bleaching assay, lime has higher antioxidant activity of 39.03% compared to lavender as of 17.55%. Antibacterial activity against S. aureus showed that both lavender and lime have good activity as of 18.13 mm and 18.06 mm, respectively. The antidiabetic activity using α-glucosidase inhibitory activity presented that lavender and lime had high activity of 89.58 % and 88.30 %, respectively. Furthermore, the total phenolic content of lavender was slightly higher as of 480.00 mg GAE/g compared to lime as of 393.33 mg GAE/g. The GC-MS analysis of essential oils showed that lavender contains linalyl acetate (38.78%), linalool (36.12%), and 1,8-cineole (8.38%), while lime contains d-limonene (73.72%), beta-pinene (9.83%) and gamma-terpinene (8.24%), respectively. The present study showed the potential use of lavender and lime essential oils for antidiabetic, antimicrobial, and antioxidant agents.
