Study on the identification of the potential Harmful Algal Bloom (HAB) species in coastal waters of Tarakan. The objectives of this study were to identify the types of potential HAB species, which cause red tide event in the coastal waters of Tarakan. Furthermore, this study was to determine the cell density of HAB species in the study area. Sampling was conducted from April to July 2012. Two sampling locations were chosen: Station 1 was located in the Port of Tengkayu 2, Tarakan and Station 2 was situated in the coastal waters of Amal. The results of the study showed that five potential HAB species were identified in Tarakan coastal waters. The species were Chaetoceros sp (class Bacillariophyceae), and four species of class Dinophyceae, which consists of Ceratium furca, Ceratium fusus, Dinophysis caudata and Protoperidinium depressum. The mean cell densities of the five HAB organisms ranged between 150-600 cells. L , 25-125 cells. L -1 . 25-150 cells. L -1 . 25-100 cells. L -1 and 25-50 cells. L -1 respectively. Chaetoceros sp dominated the area with the mean cell density of 322 ± 92 cells. L -1 compared to four other HAB species. Nevertheless, this study did not find any fish mortality events or a human illness caused by HAB species at Tarakan waters.Key word : Harmful Algal Bloom (HAB), Fitoplankton, Waters of Tarakan.

Pengembangan penelitian-penelitian mengenai ekologi plankton sangat diperlukan, karena mengingat organisme ini memiliki peranan penting sebagai produsen primer di perairan, mengetahui tingkat kesuburan perairan dan sebagai indikator dalam menentukan suatu daerah penangkapan ikan. Permasalahan yang terjadi dalam melakukan penelitian plankton khususnya untuk mengidentifikasi jenis plankton adalah tidak efisiennya dari aspek waktu. Hal ini karena pada umumnya dalam melakukan identifikasi jenis plankton para mahasiswa dan dosen di lingkungan Universitas Borneo Tarakan menggunakan buku panduan identifikasi yang cukup tebal, sehingga membutuhkan waktu yang lama untuk mengidentifikasi jenis plankton. Penelitian ini bertujuan untuk merancang program basis data, yang digunakan sebagai sistem pengklasifikasian atau mengidentifikasi jenis-jenis plankton dengan lebih efektitif dan efisien dalam pengoperasiannya. Perancangan program basis data ini menggunakan perangkat lunak aplikasi pengakses basis yaitu program Delphi dan juga MS. Access.Kata kunci : Program basis data, Identifikasi plankton

The hospital wastewater contains high organic matter and can cause the quality of water to deteriorate and affects aquatic ecosystems. The objective of this study was to design a wastewater treatment unit using aerobic-anaerobic biofilter system by examining the content of turbidity, TDS and TSS. This research was conducted from January to March 2016 at Pertamedika Hospital Tarakan. The results of study showed that the concentration of turbidity, TSS and TDS decreased 48%, 56% and 11% respectively. It can be concluded that the wastewater treatment unit by using anaerobic-aerobic biofilter system was quite effectively to reduce the concentrations of turbidity and TSS. However, the concentration of TDS has not shown a significant decrease after treatment. Keyword : Wastewater Treatment unit, Aerob-Anaerob Biofilter

Bunyu Island in the North Kalimantan province has abundant and economically valuable marine aquatic ecosystem resources, where Bunyu Island communities utilize the potential of marine aquatic ecosystems to be used as fishery potential in terms of fishing using bottom fish pots. Fishing catch is economically valuable in the form of red snapper and grouper fish found in the marine ecosystems of Bunyu Island. The research objective was to analyze the growth and size structure of the Red Snapper fish (Lutjanus argentimaculatus) and Grouper fish (Epinephalus malabaricus) originating from the waters of the island of Bunyu. Retrieval of data in the form of growth parameters are the total length and standard length, total weight, gender, gonad maturity level, and gonad weight. The results of the study of most snapper caught the length of 40,49-47,61 cm and a weight of 990,05-1.451,68 grams. While the results of the grouper study most caught were 43,73-50,13 cm in length and weights of 800,94-1.308,70 grams. The nature of growth of Red Snapper fish (Lutjanus argentimaculatus) are negative allometry. The condition index value is skinny of Red Snapper fish (Lutjanus argentimaculatus). Grouper fish (Epinephalus malabaricus) of total length and total weight is positive allometry and on the standart and fork length with total weight is negative allometri.

Macrozoobenthos are organism that can be used as bioindicators of water quality because of their population changes influenced by environmental factors. The research was conducted in the coastal flow area of Karang Anyar Pantai Tarakan City, because this area is suspected to be a source of pollutants with varying environment conditions. The purpose of research is to know the physical chemistry of the water-chemical physics area from Karang Anyar Pantai with the index diversity (H ) of macrozoobenthos as bioindicators. The Sampling methods was purposive sampling. Calculation of diversity index (H'), similarity (E), and Dominancy (D) use the Shannon-Wienner index. The variables measured include physics (temperature, brightness, current velocity, and turbidity) and chemistry (pH and DO). The results showed an abundance of macrozoobenthos ranging from 2045-4129 ind/m. The value of the Diversity index (H) of macrozoobenthos ranges from 0.19 to 0.24.Keywords: DAS Karang Anyar Pantai, diversity, Macrozoobentos
