Nitrate (NO3-) and phosphate (PO43-) are two parameters of water quality that are important for aquatic organism. Circulation of ocean currents can distribute nitrate and phosphate from one place to another. The current pattern in the waters of the Lombok Strait at the time of the tide moves from the north to the south by bringing the mass of water from the Pacific Ocean, while the movement of the current pattern at low tide moves from south to north by bringing the mass of water from the Indian Ocean. Therefore, this study aims to determine the fluctuations of Nitrate (NO3-) and Phosphate (PO43-) in Lombok Strait during one tidal period. This research was conducted on 3 - 5 November 2017 precisely at coordinates 116?1'18 "LS; -8?34'12 "BT. Sampling is done directly in the field. Seawater samples are taken on the surface and at a depth of 10 meters for 1 x 24 hours with an interval every 2 hours using a Vertical Water Sampler. Measurement of nitrate parameter using spectrophotometric method with Spectrophotometer SNI 6989 79-2011, while phosphate parameter using spectrophotometric method with UV-Vis Spectrophotometer, refer to SNI 06-6989 31-2005. The concentration of nitrate and phosphate at each time in the analysis and seen fluctuations. The concentration of nitrate and phosphate in Lombok Strait fluctuated during one tidal period. At high tide conditions, the concentrations of nitrate and phosphate are low and at low tide conditions high nitrate and phosphate concentrations.

Bali island has many magnificent underwater coral reef gardens that attract tourists. Besides Pemuteran and Menjangan island waters, Batu Sungu water has also potential to be a new tourist destination. Thus, to determine the potency and management plan in Batu Sungu waters, this research aimed to examine the overall coral cover, coral growth forms, other benthic forms, and each of their components in 5 and 10 m depths. The overall coral cover, coral growth forms, other benthic forms, and each of their components were counted by using the Line Intercept Transect (LIT) method. Before collecting data, study sites were observed by using the Manta Tow method. Data were collected in 2 depths (5 dan 10 m) with 5 sites each (replicates) that separates within 50 to 150 m. A 25 m LIT was spread parallel to the coastline above the reefs. Live coral colonies, other benthic forms below the transects were measured for the number, length, and growth forms. Water quality was measured in situ (temperature, current, and clarity) and ex situ (pH). Results showed that the category of coral coverage in Batu Sungu water is "good” in 5 m and "moderate” in 10 m whereas there was no significant difference among each component of the overall coral cover. The most dominant coral growth form among the 2 depths was Coral Massive whereas significantly abundant in 5 m. Moreover, the number of Coral Foliose was found significantly high in the same depth. Other coral growth forms were relatively similar in numbers in two depths. As likewise, the cover of other benthic forms and its component were not significantly different among two depths, except Dead Coral with Algae which significantly plentiful in 5 m. Sand was dominantly found in two depths with no significant difference. Furthermore, Coraline Alga was only observed in 5 m, however, there were no Macroalga and Alga Assemblages found at this depth. It is assumed that the similarity number of the overall coral cover, coral growth forms, other benthic forms, and each of their components is related to the alikeness of water quality among the two depths.

Benoa Bay is a highly regarded area by environmental conditions. Nitrate is important parameter for marine biota life. From previous research on nitrate contamination in Benoa Bay, the nitrate concentration has reached the standard condition of Bali Governor Regulation No. 16 of 2016 on Environmental Living Standard Quality and Living Standard Damage of 0,008 mg/L. Analysis previous researc still limited for surface water, so it is important to do more reasearch in water cloum of Benoa Bay. Research for nitrat constration can do whith observation data but the data observation need long time and many money. In this study using numerical modeling. The numerical modeler in this study is Finite Volume Coastal Ocean Model (FVCOM) which is modeled in 3-D. In the analysis of nitrate distribution in this study used the moemntum equations and advection-diffusion equations. From the model results for each condition the nitrate concentration at the surface of the Bay of Benoa is high in the western part of Benoa Bay and east of Benoa Bay. While in the water column of Benoa Bay the nitrate concentration tends to be influenced by the tidal elevation. The concentration nitrate is high in the low tide and the consectration nitrate is low in the high tide. The nitrate concentration from the surface to the bottom of the water have similar consentration.

Lombok Strait is a strait located between Bali Island and Lombok Island that has a strong current and crossed by the main trajectory of Indonesian Throughflow (ITF). ITF is a current system that connects the Pacific and Indian Ocean. When mass water ITF passes through Indonesian waters, it mixes with other water masses, resulting in a mix of two water masses from two different oceans. These differences in water mass characteristics include temperature, salinity, DO, chlorophyll, and other tracers that can be used as an indicator of productivity. This can be determined based on the availability of chlorophyll-a concentrations. Chlorophyll-a is an active pigment in phytoplankton cells that has an important role on photosynthesis process. It is essential to know the temporal fluctuations of the chlorophyll-a concentrations at both high and low tide, and the correlation between chlorophyll-a and the water quality in the Lombok Strait. This research used primary data on chlorophyll-a and water quality parameter (DO, temperature, and salinity) and secondary data regarding tides on Port of Lembar. This research used CTD SBE 911+ as a measurement of instrument. The concentration of chlorophyll-a on CTD measurement of 0 m (0.011mg/l and 0.005) and for 10m of chlorophyll-a concentration (0.014mg/l and 0.006). The fluctuations of chlorophyll-a pattern during the tides showed that at low tide, the chlorophyll-a concentration is high, and vice versa. The chlorophyll-a was situated on a depth of 0 m and 10 m and was not affected by the water quality.

Coastal areas are dynamic and vulnerable to environmental changes, both due to natural processes and human activities, the coastal waters in Kupang City are strategic in supporting the development of the economic sector. Coastal areas have unique characteristics, both in terms of bio-geophysics and social, economic and cultural aspects. Some have a high level of vulnerability to global warming. The high value of vulnerability is inseparable from the geomorphological conditions of Kupang City in the form of sandy beaches and coastal erosion. This condition caused Kupang City to become one of the areas affected by tidal flooding. This research is a preliminary study which aims to determine the potential for rob in the coastal city of East Nusa Tenggara that occurred in February 2014. The impact of the tidal floods submerged residents' houses above the knees of adults as high as 70 cm.. The results of this study were to determine the potential for tidal reoccurrence in the city of Kupang, NTT based on tidal forecasting data. Based on the results of the analysis using the Admiralty method, it was found that the Formzhal (F) value for the coast of Kupang City was 25.82, the position of the lowest water level at Oesapa 2 Beach was 206.9 cm, while the sea level elevation position reached the highest peak on Kelapa Lima 2 Beach, namely 478, 5 cm. The value of the harmonic analysis results from the coastal area of Kupang City has HHWL (Highest High Water Level) which is 340.09 cm, the MSL (Mean Sea Level) value is 212.07 cm, and LLWL (Lowest Low Water Level) is 73.36 cm based on these results. The Kupang coast has the potential for tidal flooding.

Nutrien merupakan material kimia yang penting bagi kelangsungan hidup organisme perairan. Keberadaannya di kolom perairan dapat dijadikan sebagai penentu apakah perairan berada dalam kondisi subur atau tidak. Sumber nutrien di perairan dapat berasal dari aktivitas manusia seperti pemukiman dan pertanian yang terdapat di darat dan masuk ke kawasan muara melalui aliran sungai. Meskipun demikian, masuknya nutrien dalam jumlah besar dapat menurunkan kualitas perairan karena dapat memicu terjadinya eutrofikasi. Penelitian ini bertujuan untuk mengetahui kondisi nutrien di air dan sedimen serta TSS dan karakteristik sedimen di sekitar Perairan Pulau Payung. Pengambilan sampel dilaksanakan bulan September 2022 pada 5 stasiun penelitian, analisis nitrat dan fosfat pada sampel air mengacu pada metode brusin sulfat SNI 06-2480-1991 dan SNI 6989.31-2015. Analisis nitrat pada sedimen menggunakan metode bruan dan analisis fosfat merujuk pada metode SNI 19-2483-1991. Analisis tekstur sedimen menggunakan metode ayak kering dan analisa TSS dengan metode penyaringan. Hasil penelitian menunjukkan konsentrasi nitrat di kolom perairan Pulau Payung berkisar 1,7-2,8 mg/l (telah melebihi baku mutu, 0,008 mg/L berdasarkan Kepmen LH (2004) dan 0,07 mg/L berdasarkan US-EPA (1973), sementara fosfat berkisar 0,25-0,48 mg/l (tidak melebihi baku mutu 0,2 – 1,0 mg/L berdasarkan Kepmen LH PP RI No.22 Tahun 2021). Konsentrasi nitrat sedimen Pulau Payung berkisar 24,69-40,41 mg/kg (tergolong perairan dengan kandungan nitrat tinggi) dan fosfat berkisar 1,15-1,54 mg/kg (tergolong perairan dengan kandungan fosfat sangat rendah). Sedimen Pulau Payung sebagian besar didominasi substrat lempung dan sebagian kecil lempung berpasir. Adapun nilai TSS yang ditemukan berkisar antara 115,22 – 212,97 mg/l.

The increase in anthropogenic CO2 emissions has induced significant physical and biogeochemical alterations in oceans worldwide, including warming, acidification, and oxygen depletion. Coastal areas are particularly vulnerable due to intensified human activities and terrestrial influences, resulting in increased coastal ocean acidification driven by atmospheric CO2 absorption and regional biological and anthropogenic processes. However, research on the collective impact of land-sea interaction and air-sea CO2 exchange on coastal ocean acidification in severely disturbed areas, such as the small islands of Lombok and Pari in Indonesia, remains limited. This study aims to investigate the daily fluctuations in marine carbonate systems and aragonite saturation (Ωarag) levels in the vicinity of seagrass and coral reef habitats in Pari Island and Sire Bay, Lombok. Seawater samples were collected from Sire Bay, Lombok, and the coastal waters of Pari Island to analyze the carbonate systems, CO₂ flux, and metabolic processes. The findings indicate that Pari Island's coastal waters are more susceptible to ocean acidification than Sire Bay, Lombok, showing significantly lower pH values and Ωarag (P<0.05), ranging from 7.60 to 8.00 and 1.04 to 2.54, respectively. This disparity arises from the decreased temperature and salinity in Pari Island's coastal waters during the northwest monsoon, coupled with the deteriorated state of the seagrass and coral reef ecosystems, altering the equilibrium of ecosystem productivity and calcification. The study underscores the necessity of adopting specific coastal management tactics to lessen the effects on fragile ecosystems, highlighting the urgency for additional studies to evaluate adaptive and conservation strategies to preserve coastal biodiversity and ecosystem services.
