“…There are three island clusters known as Gili Matra (Meno, Trawangan, and Air), marine tourism areas that are very well known to foreign nations as a beautiful and enchanting tourist destination. Besides being used as marine tourism, North Lombok coastal marine resources' potential is partly utilized as aquaculture and capture fisheries areas (Junaidi et al, 2018).…”

“…However, the problem occurs is the placement of mariculture locations is predictive, so needs an accurate description criterion and avoiding non-supportive environmental influences (Radiarta et al, 2005). Therefore, by extending the work by Junaidi et al (2018) and Szuster and Albasri (2010), the current study identifies the site selection criteria for marine cultivation development in North Lombok Regency followed by its evaluation.…”

“…According to Utojo and Mansyur (2007), the location can carry out the development of mariculture businesses such as coastal areas (bays) because they can protect from the influence of strong currents, large waves, strong winds, and free of pollution. Mariculture has a lively and bright prospect to be developed to increase coastal communities' income, raise local revenue, increase country foreign exchange, and avoid environmental damage (Junaidi et al, 2018). Pearl shells, seaweed, lobster, and grouper are marine fishery commodities that are frequently exported, and these four commodities are primarily developed in North Lombok Regency (see Table 1).…”

Identifying the requirements for selecting water locations for marine cultivation requires identifying and objectively selecting cultivation locations. The study aims to identify site selection criteria to develop marine cultivation in Indonesia’s North Lombok Regency, followed by their prioritization based on perceived significance. The selection criteria are through extensive review of literature, and are evaluated based on primary data. Grey Absolute Decision Analysis (GADA) model was used to evaluate the criteria. Comparative analysis with the Simple Additive Weighting (SAW) and TOPSIS methods confirmed the soundness of the results obtained through GADA. It was found that oceanographic conditions are most essential criterion for site selection for marine cultivation development. The results are important for marine cultivation businesses looking for suitable site in North Lombok Regency.

“…Activities involving marine aquaculture are indirectly or directly linked to the sea [8]. There are essentially no barriers between cultured biota and the external environment, and this connection is very intense [9]. Coastal private marine aquaculture in Bali's Buleleng Regency typically lacks a waste disposal area.…”

The highly dynamic nature of marine waters can create unique characteristics for bacterial communities. The purpose of this study was to quantify the number of bacteria present in the beach sand and coastal waters of three marine aquaculture centers in Bali, Indonesia. Two locations that have developed were selected (Patas Village and Candikusuma Village). While an advance centre was located in Sumberkima Village Bay. Sampling was done in March-April 2021. Seawater and beach sand from the three locations were collected and analyzed for total plate count bacteria, Vibrio sp., halotolerant bacteria, rod-shaped gram-negative bacteria and anaerobic facultative bacteria. Sampling of sea water was carried out at 4-5 points around floating net cages and beach sand around the location. The sampling results showed that the total plate count bacteria and halotolerant bacteria in coastal waters from the three locations were less varied. While number of Vibrio sp. in Candikusuma Village lower than the Vibrio sp. in two centre. Rod-shaped gram-negative bacteria were found in advance centre (Sumberkima Village). Sand beach bacteria from Sumberkima Village and Patas Village have similar number of total plate count bacteria, Vibrio sp., halotolerant bacteria and rod-shaped gram-negative bacteria. However, the number of these bacteria were significant different with the same bacterial on the beach sand of Candikusuma Village, except anaerobic facultative bacteria. These results indicate that the bacterial population is influenced by development of aquaculture activities in coastal waters.

Tidal Current Influence on Distributing Submarine Groundwater Discharge (SGD) Area in the North Lombok Waters, Indonesia <i><br>[Pengaruh Arus Pasang Surut dalam Distribusi Keluaran Air Tanah Lepas Pantai (KALP) di Perairan Lombok Utara, Indonesia]<i><br>

Submarine Groundwater Discharge (SGD) has been found in the North Lombok Island. This phenomenon is strongly related to the watershed from Rinjani Mountain permeated in the form of underwater seepages. The largest seepage was observed in Krakas Beach. The emergence of these seepages may affect water quality and nutrient pollution in the surrounding by which the distribution is mainly induced by the tidal current regime. This study aimed to determine the influence of tidal current on low-temperature groundwater distribution and to analyze the environmental issues resulted from this phenomenon. Flow model and statistical analysis were employed to determine the transport pattern of SGD. The tidal current moved southwestward during the high tidal condition ranging from 0-0.15 cm/s. While tidal current flowed northeastward during the low tidal condition ranging from 0-0.3 cm/s. The temperature fluctuation follows the changes of surface elevation around SGD in which the correlation value between those two parameters reached 63 percent. This proves that the cold-water transportation depends on the fluctuation of tidal current (tidal pumping), resulting in the imbalanced ecosystem, especially during the high tidal condition when a greater water mass transport takes place.AbstrakKeluaran Air Tanah Lepas Pantai (KALP) telah ditemukan di utara Pulau Lombok. Fenomena ini sangat dipengaruhi oleh daerah aliran air Gunung Rinjani yang meresap dalam bentuk rembesan bawah air. Rembesan terbesar diketahui berada di Pantai Krakas. Kemunculan rembesan ini mungkin berdampak pada kualitas perairan dan polusi nutrien di sekitarnya yang mana distribusinya sangat dipicu oleh pengaruh arus pasang surut. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari arus pasang surut terhadap distribusi air dingin dan menganalisis masalah lingkungan akibat dari kondisi tersebut. Arus pasang surut bergerak menuju barat daya saat kondisi pasang berkisar antara 0-0,15 cm/s, sedangkan arus pasang surut bergerak menuju timur laut pada kondisi surut berkisar antara 0-0,32 cm/s. Fluktuasi suhu mengikuti perubahan elevasi muka air di lokasi KALP dimana nilai korelasi dari kedua parameter tersebut mencapai 63 persen. Hal ini membuktikan bahwa transpor air dingin bergantung pada fluktuasi arus pasang surut, menyebabkan ketidakseimbangan ekosistem, khususnya pada kondisi pasang ketika mekanisme transpor masa air yang lebih besar sedang berlangsung.
