Sistem Informasi Geografis dapat digunakan untuk memetakan lahan tambak garam yang juga dapat diisi oleh banyak informasi dari pemilik, produksi, serta luasan dari tiap petak tambak garam sehingga nantinya dapat menjadi suatu informasi yang lengkap untuk keperluan database pemerintah maupun instansi terkait. Penelitian ini bertujuan untuk memetakan potensi lahan tambak garam di wilayah Kabupaten Sidoarjo serta mengetahui cakupan luas lahan produksi tambak garam di Kabupaten Sidoarjo. Hasilnya menunjukkan bahwa luas lahan tambak garam di Kabupaten Sidoarjo adalah 351,59 Ha dengan 162,5 Ha diantaranya adalah lahan produktif. Analisa yang dilakukan terhadap trend produksi garam di Kabupaten Sidoarjo menunjukkan hasil yang berfluktuatif pada periode tahun 2000 hingga 2016. Fluktuasi produksi ini diakibatkan oleh perubahan kondisi cuaca. Rendahnya produksi garam pada tahun 2005 dan 2010 diduga sebagai akibat dari pengaruh adanya musim hujan dengan periode yang panjang.

ABSTRAKPemutihan karang merupakan salah satu dampak dari perubahan iklim global, kenaikan suhu tersebut memberikan dampak negatif bagi keseimbangan ekosistem terumbu karang. Terumbu karang yang memutih dan kehilangan zooxanthella nya akan rentan terkena infeksi dan penyakit. Populasi komunitas ikan karang pemakan hewan karang dan makrozoobenthos juga akan menurun. Tujuan dari penelitian ini adalah untuk mengetahui besar dampak kerusakan terumbu karang dan dampaknya bagi populasi ikan dan makrozoobenthos. Survey dilakukan pada 3 titik di wilayah perairan Tejakula dengan metode reefcheck. Hasil penelitian menunjukkan kematian terumbu karang sebesar 5-7.5%, jumlah alga yang menutupi 3.125%. Kondisi ikan kepe-kepe yang merupakan pemakan hewan karang juga sudah ditemukan dalam jumlah cukup banyak. Keberadaan ikan herbivora dan makrozoobenthos herbivore membantu mengurangi jumlah alga yang menutupi. Sedangkan keberadaan ikan pemakan terumbu karang dan ikan predator memperlihatkan bahwa sistem ekologi yang ada di terumbu karang tersebut hampir kembali normal. Kata Kunci: terumbu karang, komunitas ikan karang, makrozoobenthos.The Impact of Hard Coral Bleaching in Coral and Macrozoobenthos Fish Communities in Tejakula, Buleleng, Bali Water AreasABSTRACTCoral bleaching is one of the consequences of global climate change, as the rise of temperature negatively impacts the ecological balance of reef ecosystems. Bleached coral reefs lose their zooxanthellae, increasing vulnerability to infection and disease and consequently, causing population decline of macrozoobenthos and reef fish communities which prey on coral-consuming organisms. This research aims to determine the degree of coral reef damage and its impact on fish and macrozoobenthos population. The survey was conducted on 3 stations in Tejakula waters with the reef check method. Results show that coral reef death reaches 5-7.5%, with algal coverage of 3.125%. Kepe-kepe fish which prey on coral-consuming animals were also found in relatively high abundance. The presence of herbivore fish and macrozoobenthos help reduce algal cover. Meanwhile, the presence of coral-consuming and predator fish indicate that the coral reef ecological system has mostly returned to normal. Keywords: coral reef, reef fish community, macrozoobenthos

The coastal area of the Madura Strait stretches from Surabaya City to the east to Situbondo Regency and includes the southern part of Madura Island. The aim of this research is to map the suitability of the waters and coastal areas of the Madura Strait using GIS modeling. Mapping of the designation of the waters and coastal areas of the Madura Strait was carried out by overlaying spatial data covering bio-physical parameters including water transparency, pH, water substrate, temperature, salinity, and depth. The designation of water areas is divided into three classes, namely capture fisheries, tourism and conservation purposes. The spatial data used comes from several sources, namely the results of water quality surveys, Landsat 8 satellite imagery, bathymetry data / sea depth and Rupa Bumi Indonesia (RBI) maps at a scale of 1: 25,000. For water quality data comes from the results of a survey by the Marine and Fisheries Service of East Java Province in 2019 at 78 observation points in the waters of the Madura Strait. Water quality parameters used in GIS modeling are pH, salinity, brightness and temperature. The data for each observation point were then interpolated using the Kringing method. Landsat 8 satellite imagery is used to map the condition of the bottom substrate waters. Meanwhile, the depth data was downloaded from GEBCO (General Bathymetric Charts of the Oceans). The result of overlaying thematic maps shows that 37.69% (8586.69 km2) of the area of the Madura Strait is suitable for capture fisheries activities, then 10.28% (2341.02 km2) is suitable for marine tourism areas and 19.06 % (4343.4 km2) suitable for conservation areas. Meanwhile, 32.97% (7511.94 km2) can be used as conservation and tourism areas.

The abundant biodiversity at Jemeluk Beach does not guarantee that all marine tourism activities and activities do not damage and have a negative impact on the environment. The tourism potential of Jemeluk Beach is the existence of coral reefs and many types of reef fish so that it is suitable to be used as marine tourism, one of which is diving and snorkeling. This research aims to analyze the suitability index and carrying capacity of diving and snorkeling tourism at Jemeluk Beach in order to become a well-managed tourist attraction and develop in the sustainability corridor. The analysis used in this research is the analysis of the suitability and carrying capacity of the area, namely by comparing the characteristics and quality of land against land use requirements for certain tourism activities while still paying attention to the capacity of the area to accommodate tourism activities in order to maintain environmental sustainability and natural preservation. The method of measuring coral reefs using the UPT (Underwater Photo Transect) method which is based on the shape of coral growth. Measurement of the type and number of reef fish was studied using the UVC (Underwater Visual Census) method by taking data along 50 meters at the same depth as the data collection of coral reef cover. The condition of the suitability of diving tourism at points I, II and III has the same value of 1.6 and is classified as unsuitable. In contrast to diving tourism, the condition of the suitability of snorkeling tourism at points I and II has the same value of 2.1 and is classified as suitable category, while point III has a value of 2.48 and is classified as suitable category to be used as an object of marine tourism development. The results of the calculation of the carrying capacity of the area for diving tourism that can be accommodated as many as 404 people/day while snorkeling tourism is 31 people/day.

Reef fish associated with artificial reefs are one indicator of success for artificial reef applications. This research was carried out in February 2023. Reef fish data was collected in three tidal conditions. Data of Coral fish was collected using the Underwater Visual Census (UVC) method. The data that collected includes abundance of species, individual abundance and fish size from 3 categories namely major, indicators and targets. From the results, the community structure at each location obtained the same diversity index and uniformity index which were classified as moderate to high and the dominance index was classified as low. For each tidal condition the diversity index obtained was classified as medium to high, the uniformity index is relatively high and the dominance index is low. The total abundance of species at each point ranges from 26 species represented by 13 families to 63 species represented by 19 families, and for each tidal condition it ranges from 11 species represented by 7 families to 42 species represented by 16 families. The total abundance of individuals at each point overall ranged from 1333-20,048 Ind/Ha, each tidal condition it ranges from 20- 980 individuals. The total biomass at each point overall ranged from 102,844- 1353,119 Kg/Ha, each tidal condition ranges from 2,154 to 63,780 kg. Based on the results, the species similarity index values at each point were categorized as medium, except for Les II and Galeri, which were classified as high, while the test results for each tidal condition ranged from medium to high at each point. Test results (Mann-Whitney) for each point based on individual abundance values and coral reef fish biomass generally showed significant differences except between the Gallery and Les II points, whereas for each tidal condition there were no significant differences. Based on the results of the Correspondence Analysis, it was found that there was a relationship between several types of fish with each research point and at each tidal condition, this shows that the artificial reef structure at each point and each tidal condition was successful in attracting fish populations.
