Abstract

The Mandalika Coastal Area, located in Central Lombok Regency, is a row of beaches and bays that have a large coral reef ecosystem and intertidal zone area. The increasing growth of activities on the Mandalika coast will affect the life of the coral reef ecosystem, one of which is the concentration of heavy metals that exceeds the quality standard limits which will be very dangerous for coral reefs. This study aims to determine the concentration of the heavy metals lead and cadmium in Porites lutea coral reefs in Kuta, Tanjung Aan and Gerupuk beaches. Research data collection (field and laboratory) was carried out in May 2023. Coral reef preparation was carried out at the Advanced and Analytical Biology Laboratory, FMIPA, University of Mataram and measurements of heavy metal content were carried out at the Environmental Laboratory, the West Nusa Tenggara Province Environment and Forestry Service. Measurement and calculation of heavy metal content using Atomic Absorption Spectrophotometry (AAS). The results showed that the concentrations of the heavy metals lead and cadmium in Porites lutea coral reefs are < 0.0005 mg/L and < 0.0001 mg/L, which are still below the quality standards (PPRI No.22 of 2021 concerning Sea water Wuality Standards on Marine Biota). The Bioaccumulation Factors (BAF) value in all samples of P. lutea coral in Mandalika coastal waters is 0.00 mg/L, this shows that there is no accumulation of heavy metals in P. lutea coral.

Abstract

The Sasak tribe, who are the indigenous inhabitants of Lombok Island, use banten (Lannea coromandelica (Houtt.) Merr.) leaves as a medicinal plant to reduce fever. Fever is a physiological response to infection, characterized by a body temperature above the normal range of approximately ± 37 ℃. If left untreated, fever can cause dehydration, lack of oxygen, nerve damage, dizziness, decreased appetite, weakness, and muscle pain. To minimize these effects, antipyretics such as paracetamol can be used. However, prolonged or excessive use of paracetamol can cause hepatotoxicity, hepatic necrosis, renal tubular necrosis, and hypoglycemic coma.  Therefore, it is necessary to develop alternative herbal medicines to treat fever. The aim of this study is to determine the content and antipyretic effect of banten leaf extract, which was obtained through ethanol extraction. The antipyretic ability test utilized five groups: the negative control group, positive control group, and test groups receiving doses of 1 mg/25gBB, 3 mg/25gBB, and 10 mg/25gBB of ethanol extract of banten leaves. Fever induction was induced using the DPT-HB vaccine. The study found that the ethanol extract of banten leaves contained flavonoids (572.38 mg QE/gram extract), phenols (200.82 mg GAE/gram extract), and antioxidants (2.5063 mg GAE/gram extract with DPPH). The percentage of antioxidant inhibition in banten leaves between 9.68-47.16 %. Additionally, all test groups of the ethanol extract of banten leaves exhibited antipyretic activity. The antipyretic effect of the 3 mg/25gBB dose was equivalent to that of paracetamol. Similarly, the antipyretic effect of the 10 mg/25gBB dose was almost identical to that of paracetamol at 5 hours after treatment.

Abstract

The West Sekotong coastal area, which includes mangrove, seagrass, and coral reef ecosystems, is rich in marine biota, particularly phytoplankton communities. These ecosystems have been designated as conservation areas; however, increasing exploitation and disturbances in the region have impacted the presence and distribution of phytoplankton. This study aimed to assess the distribution, abundance, and species diversity of phytoplankton across these three ecosystems. Using purposive sampling, phytoplankton communities were identified microscopically, revealing a total of 742 phytoplankton cells, with 264 cells in the mangrove, 258 cells in seagrass, and 220 cells in the coral reef ecosystems. The class Bacillariophyceae dominated across all ecosystems. Specific species dominance varied, with Skeletonema costatum prevailing in mangroves, Nitzschia sigmoidhea in seagrass, and Coscinodiscus radiatus in coral reefs. The highest similarity index (35.89%) was observed between mangrove and seagrass ecosystems, while the lowest (30.87%) occurred between mangrove and coral reefs. The species richness index (R) was high in all ecosystems, ranging from 6.45 to 10.26, and dominance indices were low, indicating a balanced community structure. Environmental parameters measured across the ecosystems showed no significant differences and met the quality standards for marine biota as per KEPMENLH No 51 2004.

Abstract

Kegiatan pengabdian kepada masyarakat dengan tema “Sosialisasi dan Pelatihan Transplantasi Karang” telah dilaksanakan pada Jumat, 5 September 2025, di pesisir Pantai Sire, Kabupaten Lombok Utara. Kegiatan ini bertujuan untuk meningkatkan pengetahuan, kesadaran, dan keterampilan masyarakat pesisir dalam menjaga ekosistem terumbu karang melalui penerapan teknologi transplantasi karang yang sederhana, murah, dan ramah lingkungan. Program dilaksanakan secara partisipatif melalui dua sesi utama, yaitu penyampaian materi melalui ceramah dan diskusi interaktif mengenai ekologi terumbu karang dan teknik rehabilitasi habitat, serta demonstrasi dan praktik langsung transplantasi karang menggunakan rak besi sebagai media tanam yang melibatkan seluruh peserta secara aktif. Hasil kegiatan menunjukkan respons positif dan antusiasme tinggi dari peserta, yang tercermin dari keterlibatan aktif dalam diskusi serta munculnya ide-ide baru dalam pengelolaan kawasan pesisir ke depan. Selain memberikan manfaat ekologis, kegiatan ini juga membuka peluang peningkatan ekonomi masyarakat melalui pengembangan wisata bahari. Rencana tindak lanjut meliputi monitoring pertumbuhan karang hasil transplantasi, pelatihan lanjutan, pembentukan kelompok masyarakat peduli lingkungan, dan penerapan inovasi berkelanjutan. Diharapkan kegiatan ini dapat menjadi langkah awal yang berkelanjutan dalam mendorong partisipasi masyarakat dan pemangku kepentingan lokal untuk bersama-sama mendukung upaya konservasi dan rehabilitasi ekosistem terumbu karang di kawasan pesisir Lombok Utara.
