Drone for a Cleaner Coast: Monitoring and Analysis of Marine Debris at Sindulang Beach
Get PDFThis research aims to evaluate the capabilities of the DJI Phantom 4 Pro unmanned aerial vehicle (UAV) in monitoring the accumulation points and analyzing the characteristics of marine debris stranded at Sindulang Beach. The research methodology employed a descriptive approach with a survey method, including data collection through observation, documentation, and direct field surveys. Aerial photos were obtained from the drone, along with ground photography using a GPS map camera and the drone itself. Data analysis was conducted using Agisoft Metashape Professional and ArcGIS 10.8 software to map the distribution of marine debris accumulation points. The drone monitoring results allowed us to describe the characteristics and variations in types of marine debris, with plastic waste dominating, followed by glass, rubber, and fabric debris. The DJI Phantom 4 Pro unmanned aerial vehicle produced high-resolution aerial photos, enabling the identification of the distribution of marine debris accumulation points at Sindulang Beach and the creation of distribution maps along the Sindulang coastal area. The mapping results provide valuable information about the distribution of debris on Sindulang Beach. Based on the monitoring results using the unmanned aerial vehicle (UAV) or drone, it was found that approximately 80% of the intertidal area at Sindulang Beach was covered by debris, indicating a significant level of pollution.

Penelitian ini bertujuan untuk mengevaluasi kemampuan pesawat tanpa awak DJI Phantom 4 Pro dalam pemantauan titik kumpul sebaran marine debris serta menganalisis karakteristik marine debris yang terdampar di Pantai Sindulang. Metode penelitian yang digunakan adalah pendekatan deskriptif dengan metode survei lapangan, termasuk pengumpulan data melalui observasi, dokumentasi, dan survei langsung. Foto udara diperoleh dari drone dan pemotretan darat menggunakan kamera GPS Map serta drone. Data dianalisis menggunakan perangkat lunak Agisoft Metashape Professional dan ArcGIS 10.8 untuk memetakan sebaran titik kumpul sampah laut. Hasil pemantauan dari drone memungkinkan kita untuk mendeskripsikan karakteristik dan variasi jenis sampah laut, dengan dominasi sampah plastik diikuti oleh sampah kaca, karet, dan kain. Pesawat tanpa awak DJI Phantom 4 Pro menghasilkan foto udara dengan resolusi tinggi, yang memungkinkan identifikasi sebaran titik kumpul sampah di Pantai Sindulang serta pembuatan peta sebarannya di sepanjang pesisir laut Sindulang. Hasil pemetaan ini memberikan informasi yang berharga tentang penyebaran sampah di pantai Sindulang. Berdasarkan hasil pemantauan menggunakan Unmanned Aerial Vehicle (UAV) / Drone, ditemukan bahwa sekitar 80% area pasang surut di pantai Sindulang telah tercakup oleh sampah, menunjukkan tingkat pencemaran yang signifikan.

Exploring Metabolites Of Green Algae Caulerpa Spp. To Discover Putative Inhibitors Of Dpp-4, A New Antidiabetic Target Protein: Molecular Docking Compounds from Marine Green Algae
No full textDiabetes mellitus (DM) remains a serious global health threat, claiming a million lives every year and affecting nearly 9% of the adult population who suffer from this impaired insulin sensitivity disease. The Dipeptidyl peptidase-4 (DPP-4) enzyme has recently attracted attention because of its crucial role in insulin signaling, making this enzyme an interesting and emerging target for antidiabetic drug discovery. This study aimed to explore reported metabolites from marine algae of the genus Caulerpa as DPP-4 inhibitors through computational studies using CB-dock 2, Protein-Ligand Interaction Profiler, SwissAdme, and pkCMS. Molecular docking allowed the identification of 7 hit compounds with strong binding affinities (8.4 kcal to 9.3 kcal/mol) against DPP-4 target enzyme PDB ID: 3G4I. Four hits showed stronger binding affinity than two DPP-4 specific inhibitors and FDA-approved antidiabetic drugs, sitagliptin (8.4 kcal/mol) and linagliptin (9.0 kcal/mol). Following a molecular modification of the hit compounds using a bioisosterism-like approach and ADMET evaluation with pkCMS, three putative DPP-4 inhibitors were identified. They showed either stronger binding affinities or better ADMET profiles than sitagliptin and linagliptin, suggesting their promising potential as DPP-4 inhibitors. However, further optimized bioisoterism, in silico and in vivo studies, and clinical-based trials are required to confirm their antidiabetic activity.

Analysis Of Particle Content In Kappaphyccus alvarezii Seaweed In The Waters Of Arakan Village Using Scan Electron Microscopy–Energy Dispersive X-ray Spectroscopy (SEM-EDX)
Get PDFKappaphycus alvarezii seaweed is widely cultivated in Indonesia and has important economic value. Nevertheless, this seaweed is easily attacked by diseases. This study was to determine the ice-ice triggers in seaweed farming locations. This research study was conducted at Arakan Village, South Minahasa, North Sulawesi. We performed the bacteria isolation on the infected thallus of Kappaphycus alvarezii and found Staphylococcus arlettae caused the infection. Staphylococcus aureus used to be found on the skin and mucous membranes of healthy humans, while Staphylococcus epidermis inhabits only the skin of healthy humans. Approximately 30% of the normal healthy population was affected by Staphylococcus aureus as it asymptomatically colonizes human hosts. How this Staphylococcus arlettae (mainly found in pork farms) infected Kappaphycus alvarezii which is in a high salinity environment requires an in-depth study. We completed the experiment by using Scan Electron Microscopy–Energy Dispersive X-ray Spectroscopy (SEM-EDX), analysis on infected thallus Kappaphycus alvarezii, and a series of bacteria isolation to observe the morphology and the element contents of Staphylococcus arlettae bacteria has successfully attached to the surface of Kappaphycus alvarezii and caused an infection. This proves that environmental changes have stimulated pathogenic bacteria Staphylococcus arlettae in the area where Kappaphycus alvarezii is cultivated. The mechanism of biosorption by microbes that can live in environments that are contaminated with Pb metal is active uptake. This mechanism occurs simultaneously in line with the consumption of metal ions for the growth of microorganisms. Staphylococcus arlettae are resistant to heavy metals due to the ability to detoxify the influence of heavy metals in the presence of protein or granular material. From the results of the study using SEM-EDX of algae and bacteria Staphylococcus arlettae, it can be concluded that the content of the particle of metal in thallus triggers bacteria to live on the seaweed as an energy source.

Application Of Pes Fertilizer To The Growth Of Kappaphycus alvarezii Plantlets
Get PDFThis study aims to determine the growth of Kappaphycus alvarezii plantlets applied with different PES fertilizers. This research was conducted at Blitok Installation, brackish water aquaculture center, Situbondo. This study began with the preparation of water as a maintenance medium, acclimatization of plantlets in the greenhouse, maintenance of plantlets in the greenhouse (plantlet cleaning, fertilization), and checking water quality. The application dose of PES fertilizer given as treatment was 15 ml, 20 ml, and 25 ml which was repeated 3 times. The rearing design used a completely randomized design (CRD) model. The results obtained showed that the average absolute weight gain of planlets from the 15 ml treatment was 0.249 g - 0.271 g, the 20 ml treatment was 0.35 g - 0.432 g, and the 25 ml treatment ranged from 0.306 g - 0.372 g. For the specific growth rate from the first to the fifth week of rearing, the 15 ml treatment ranged from 3.162-1.693, the 20 ml treatment ranged from 3.922-4.21 and the 25 ml treatment ranged from 2.899-3.904. From the results of the study, it can be concluded that the application of a PES fertilizer dosage of 20 ml gave better growth than the 15 ml and 25 ml doses.
