Abstract

The research entitled "Primary Phytoplankton Productivity in the Mandalika Coastal Waters Special Economic Zone, Central Lombok Regency" was conducted from March to August 2023. This study aims to analyze the primary productivity of phytoplankton, physical and chemical parameters in Mandalika Coastal waters at three different station: station I (Kuta Beach), stasion II (Tanjung Aan), and stasion III (Gerupuk Bay) using dark and light bottles. The research results show that the Mandalika Coastal waters have phytoplankton primary productivity values ranging from 122,619 – 329,166 mgC/m2/day. The lowest productivity value (122,619 mgC/m2/day) occurs at station III these were classified as mesotrophic. Station III has also relatively lower physical and chemical parameter values such as an average pH of 7,7 mg/L and an average temperature of 29ºC compared to other stations. The highest productivity value accured at stasions II and I (329,166 mgC/m2/day and 189,285 mgC/m2/day) both were classified as eutrophic. These were supported by pH worth 7.8 mg/L and temperatures ranging from 29,3 – 29,7 ºC, where the value is relatively higher than in station III.

Abstract

The high level of construction and community activities at Kecinan Beach can affect the condition of the coral reef ecosystem. The health condition of the coral reef ecosystem can be assessed by the percentage of live coral cover within the ecosystem. North Lombok is one of the regencies on the island of Lombok that has experienced coral reef ecosystem damage, with this regency having the lowest percentage of live coral cover compared to other regencies. This study aims to determine the diversity of coral reef lifeform types and assess the health status of coral reefs at Kecinan Beach, North Lombok Regency. Data on coral reef lifeform types were observed using Coral Finder 2.0 Indo Pacific. Data collection was conducted using the UPT (Underwater Photo Transect) method at two different depths: 1-5 meters and 6-10 meters. The research results indicate that the coral reef ecosystem at Kecinan Beach is in poor condition. The percentage of live coral cover at depths of 1-5 meters is 3,58%, and at depths of 6-10 meters is 0,90%. There is ten types of coral reef lifeforms were found distributed across both depths: Acropora branching, Acropora tabulate, coral branching, encrusting, foliose, heliopora, massive, millepora, mushroom, and submissive. Diversity, evenness, and dominance indexs shows even distribution of lifeforms with no dominant species in the coral reef ecosystem at Kecinan Beach, North Lombok.

Abstract

The increasing amount of plastic consumption in Indonesia has an impact on the accumulation of plastic waste on land as well as water, with the nature of plastic that is difficult to decompose by microorganisms causing many organisms to be polluted by the waste. Therefore, research on microplastic content needs to be done to determine the safety of fish which is the food of the community. This study was conducted to find out how the abundance of microplastics as well as the characteristics of microplastics contained in Ikan Tongkol  (Euthynnus affinis) at PPI Tanjung Luar, through an isolation process using a 10% KOH solution added to fish meat, then incubated until both were homogeneous in a water bath at 70°C, 150 rpm. Furthermore, the homogenized sample was filtered using a 250 µm graded sieve. After filtering the sample will be put into a dryer at 40°C for 2 hours before being observed under a microscope. The results of this study indicate that microplastics have accumulated in fish with an abundance of 8.6 MP/Ind with the type of microplastics that most accumulates in the meat of Tuna (Euthynnus affinis) is fiber type microplastics as much as 81% of the total sample and the most dominant color is black. There are 4 microplastics found accumulated in the meat of Euthinnus affinis, namely 81% fiber, 11% fragments, 6% film, and 2% granules.

Abstract

Macroalgae are multicellular lower plant organisms that live in water, especially in marine waters. Macroalgae better known as marine algae are macroscopic algae that can reach several meters in length. Macroalgae are a highly diverse group of organisms in terms of morphology, level of structural complexity, and size. They play an important role in maintaining ocean water quality, reducing coastal erosion, and providing habitat for a wide variety of marine life. This study aimed to identify the macroalgae species present in the Sire Beach area and determine the ecological index of macroalgae in the Sire Beach area. This study was conducted from October to December 2024. Data collection was carried out using the transect method along the coastline with a transect size of 50 m perpendicular to the coastline. The macroalgae data found in this study are categorized into three classes, seven orders, seven families, nine genera, and 15 species of macroalgae. The macroalgae types found include eight species of the phylum Chlorophyta, four species of the phylum Phaeophyta, and three species of the phylum Rhodophyta. Chlorophyta (green algae) is the most common type of macroalgae in Shira Beach. The diversity index (H\') in this study was 2.47, indicating a moderate diversity of macroalgae. The evenness index value obtained is 0.91 which indicates that the evenness value is high. The dominance index in this study is 0.11 which indicates that the level of dominance is low. The obtained Margarev's wealth indicator is 3.69, indicating that the richness of the seeds is moderate.

Abstract

Terumbu karang memiliki peranan ekologis dan ekonomi yang sangat penting, khususnya bagi Pulau Lombok yang dikenal sebagai destinasi wisata bahari internasional sekaligus lumbung perikanan nasional. Namun, ekosistem ini terus mengalami penurunan kualitas, termasuk di wilayah pesisir Kabupaten Lombok Barat, salah satunya di kawasan Pantai Cemara. Kondisi tersebut menuntut adanya kesadaran kolektif dan partisipasi aktif dari berbagai pihak dalam menjaga serta merehabilitasi terumbu karang. Universitas Mataram, sebagai institusi akademik, turut berkontribusi melalui pemikiran dan implementasi program percontohan rehabilitasi. Salah satu metode yang dinilai sederhana, ekonomis, dan efektif untuk pemulihan terumbu karang adalah teknik transplantasi. Kegiatan ini bertujuan untuk membuat demplot percontohan rehabilitasi terumbu karang dengan menggunakan metode transplantasi di kawasan pesisir Pantai Cemara, Kabupaten Lombok Barat. Program dilaksanakan secara partisipatif selama tiga bulan pada tahun 2024 dengan tahapan meliputi survei lokasi, koordinasi dengan pemangku kepentingan lokal, pembuatan media transplantasi, penempatan media pada lokasi rehabilitasi, pemilihan induk karang, pengambilan fragmen karang, serta pemasangan transplantasi pada media yang telah disiapkan dan pemasangan tanda lokasi transplantasi. Diharapkan kegiatan ini dapat menjadi model percontohan sekaligus memberikan motivasi bagi masyarakat dan pemangku kepentingan dalam mendukung upaya konservasi dan rehabilitasi ekosistem terumbu karang.
