Abstract

Several activities affect the distribution of gastropods and bivalves, one of which is the activity of the community around the coast which is thought to affect water quality. The entry of organic and inorganic contaminants into coastal waters is thought to cause a decrease in water quality followed by changes in physics, chemistry and biology. The purpose of this study was to determine the diversity of gastropods and bivalves in the waters of Jukung Bay, Ujung Betok Hamlet, Pemongkong Village, Jerowaru District, East Lombok Regency. This research was conducted in Ujung Betok Hamlet (Tukung Bay Waters), Pemongkong Village, Jerowaru District, East Lombok Regency. the study was conducted from October 2022 to July 2023. The results showed that the highest species abundance was found in the Gastropoda class Nassarius sp with an abundance of 31 individuals/m2. The highest gastropod and bivalves diversity index value was obtained at point 3, namely 0.42 individuals/m2. The highest gastropod and bivalves uniformity index value was obtained at point 2 with a uniformity index value of 0.28. The dominance index value obtained was 0.1-0.56 individuals/m2 included in the moderate dominance category. Based on the results and discussion it is known that the abundance of gastropods and bivalves in the coastal waters of Jukung Bay which were analyzed totaled 108 individuals. The diversity index (H') obtained in this study ranged from 0.41-1.39 individuals/m2. The uniformity found ranged from 0.14 to 0.28 individuals/m2. The dominance index obtained ranged from 0.1 to 0.56 individuals/m2.

Abstract

Penurunan parameter kualitas air pada masa budidaya umumnya oleh bahan organik, dimana akan menyebabkan menurunnya system imun ikan terhadap penyakit. Untuk mengantisipasi penumpukan bahan organik di wadah budidaya maka diperlukan suatu system yang terintegrasi untuk mengurangi bahan organik. Tujuan penelitian ini adalah untuk melihat pengaruh penambahan kerang air tawar untuk meningkatkan kualitas air  dilihat dari nilai Amonia dan TSS dan mengetahui dampak lanjutan dari kondisi kualitas air tersebut terhadap pertumbuhan panjang dan berat ikan mas. Penelitian ini dilaksanakan selama 60 hari. Bertempat di laboratorium budidaya perairan Universitas Mataram. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL). Terdiri atas 4 perlakuan 3 kali ulangan. Perlakuan yang di uji cobakanya itu penambahan kerang air tawar dengan jumlah yang berbeda yaitu K1 (Kontrol), K2 (15 Ekor kerang air tawar), K3 (20 Ekor kerang air tawar), K4 (25 Ekor kerang air tawar). Parameter penelitian yang diukur yaitu parameter kualitas air yaitu suhu (27,1-27,9), Ph (7,1-8,4), DO (4,8-6,6), ammoniak (0,15-0,25) dan TSS terendah (54,04). Parameter pertumbuhan seperti tingkat kelangsungan hidup tertinggi pada perlakuan K2 (98,33%), laju pertumbuhan panjang tertinggi pada K2 dan K4 yaitu (3,41), pertumbuhan bobot mutlak tertinggi pada perlakuan K4 (16,03) dan laju pertumbuhan bobot spesifik tertinggi pada perlakuan K4 (0,70). Data dianalisis menggunakan sidik ragam (Anova) dengan tingkat kepercayaan 95%, kemudian dilanjutkan dengan uji Duncan. Hasil penelitian menunjukan bahwa penambahan kerang air tawar sebagai biofilter pada pemeliharaan benih ikan mas dapat mempengaruhi kualitas air pada parameter pH, DO, dan TSS serta berpengaruh nyata terhadap tingkat kelangsungan hidup, laju pertumbuhan panjang, pertumbuhan bobot mutlak dan laju pertumbuhan bobot spesifik.  Dapat disimpulkan bahwa penambahan kerang air tawar dapat menghambat penurunan kualitas air karena penumpukan bahan organik.

Abstract

Nutrition is a very important element in supporting the process of growth and development of marine organisms. The main source of natural phosphate and nitrate comes from the waters themselves through the process decomposition, the remains of dead organisms, wastedomestic, agricultural, animal husbandry, and feed residues which will be decomposed by bacteria so that they become nutrients. This research was conducted from September 2022 to July 2023 with 15 sampling points. The purpose of this study was to determine the nutrient content (ammonia, nitrate, and phosphate) and their distribution patterns in the waters of Swage Bay, East Lombok. The method of collecting data on samples and water quality directly and then the water samples were analyzed at the Marine Science Oceanography Laboratory, Mataram University. The water samples that have been described are then made a distribution pattern using the ArcGIS application with the IDW method. The content of nitrate concentrations in Swage Bay waters ranges from 0.172 – 1.624 mg/l, phosphate around 1.31 – 3.12 mg/l, and ammonia around 0.256 – 2.8 mg/l which exceeds the seawater quality standards set by Government Regulation No. 22 of 2021 and distribution pattern of nutrients nitrate, phosphate, and ammonia is quite varied. Factors that influence the distribution pattern are temperature, pH, DO, in the waters of Swage Bay, East Lombok.

Abstract

Mentigi Beach in North Lombok Regency has potential for coastal tourism; however, site-specific information on its tourism suitability based on physical beach characteristics and supporting water quality measurements remains limited. This study aimed to assess the suitability of Mentigi Beach for coastal tourism using the Tourism Suitability Index (TSI) and to describe water quality based on temperature, salinity, and pH. The study was conducted in August 2026 at three purposively selected observation stations in Mentigi Beach, Malaka Village, Pemenang District, North Lombok Regency. The TSI assessment covered ten parameters: beach type, beach width, seabed substrate, water depth, water clarity, current velocity, beach slope, coastal land cover, hazardous biota, and freshwater availability. Water quality was evaluated with reference to Government Regulation of the Republic of Indonesia No. 22 of 2021. The TSI values at Stations 1, 2, and 3 were 2.80, 2.59, and 2.79, respectively, with an average of 2.73, indicating the Highly Suitable category. Water temperature ranged from 28.7 to 28.8°C, salinity was 34 ppt, and pH ranged from 7.8 to 7.9. These measurements provide supporting environmental information for interpreting the physical suitability results. Overall, the three surveyed stations were classified as highly suitable for beach tourism based on the assessed TSI parameters. These findings apply to the surveyed stations and provide preliminary site-specific information for coastal tourism assessment at Mentigi Beach.
