Abstract

The abundant natural potential in the Belawan coastal area has great opportunities for the development of various activities. In addition, the Belawan coastal area is also vulnerable to high pollution, especially because of its role in supporting the regional economy through sectors such as tourism, fisheries, transportation, and industry. Effective waste management is a special concern of the government along with maximum efforts in developing economic potential. Waste has become a global problem, especially in Indonesia with its increasing population growth. This research aims to analyze strategies for controlling pollution from waste in the Belawan coastal area. The method used is a Likert Scale to evaluate the community's perception of the issue of waste problems. On the economic aspect, the community assessed that waste management has not had a significant impact, but on the social aspect, waste management was rated positively with the highest score reaching 68,80 which was obtained on waste management activities that increased fraternal ties. The problem of low sanitation awareness is the main obstacle that requires solutions based on community participation in waste management.

Abstract

Jatigede Reservoir receives water masses and materials from the Cimanuk River, such as nutrients, sediments, and waste, including microplastics. This study aims to analyze the presence of microplastics in the digestive tract of caught fish in Jatigede Reservoir. Fish samples were obtained from fishermen, fish collectors, and fish farmers. Microplastic observations were carried out in the stomach and intestines of fish through the stages of observing fish eating habits, extraction, followed by FTIR analysis to determine the presence, abundance, and type of polymer. Carnivorous fish have the highest amount of microplastics. There is a marked difference between the amount of microplastics and the origin of fish intake. The shorter the fish's gut, the greater the amount of microplastics found. Based on their shape, the type of microplastic is dominated by fibers with a blue color. The most common polymer found is nylon. The digestive tract of fish in Jatigede Reservoir already contains microplastics of various types and colors, with varying amounts, according to the nature of eating fish.

Abstract

Coastal waters of Bojonegara in Banten Bay has a lot of pressure from the surrounding environment, including industry and sand mining. The high intensity and limited space encourage reclamation in coastal areas which can trigger changes in water quality. Research was conducted from October to December 2019, aims to analyze the phytoplankton biodiversity and pollution bioindicator of the waters. The phytoplankton was obtained through filtering 50 liters of water at a depth of 30 cm or surface waters. Observations were also made on water quality conditions including transparency, depth, color, temperature, pH, salinity, and dissolved oxygen (in-situ) and turbidity, Total Suspended Solid (TSS), nitrate, nitrite, and total phosphate (ex-situ). Data analysis was performed on abundance, diversity index, eveness and dominance, similarity index, and saprobic index. Based on observations, it is known that the phytoplankton found were in the class Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, and Chrysophyceae. The index values of diversity, eveness, and dominance of phytoplankton each ranged from 0.2223-1.0070; 0,1289-0,5664; and 0.1550-0.8181, respectively. According to these values, the Bojonegara waters were classifeied as mild to moderate ecological pressure. The similar conditions are also indicated by the saprobic index values. The result of Main Component Analysis (PCA) shows the first component with 53.726% variance represented by turbidity parameters, TSS, total phosphate, transparency, depth, temperature, pH, and DO. These parameters have the most influence on the presence of phytoplankton.

Abstract

Waduk Jatigede merupakan perairan daratan tergenang yang terbentuk dari pembendungan sungai Cimanuk. Waduk Jatigede, sebagaimana waduk umunnya, secara horizontal terbagi atas tiga wilayah, yaitu riverin, transisi, dan lakustrin. Perbedaan karakteristik setiap zona juga berdampak pada komposisi dan komunitas fitoplankton, status trofik, dan kandungan karbon. Penelitian ini bertujuan untuk mengalkulasi seberapa besar kandungan karbon pada fitoplankton di perairan Waduk Jatigede pada setiap zona dengan komposisi dan komunitas fitoplankton pada status trofik tertentu. Stasiun penelitian dipilih menggunakan purposive sampling dengan pemilihan stasiun berdasarkan zona dalam waduk, yaitu riverin, transisi, dan lakustrin. Analisis status trofik dan kandungan karbon digunakan untuk mengetahui kondisi dan keberadaan karbon di Waduk Jatiged. Status trofik Waduk Jatigede berdasarkan Indeks Nygaard dan TSI (Tropic State Index) dikategorikan ke dalam tingkat kesuburan eutrofik. Jenis-jenis dari Kelas Cyanophyceae memiliki kelimpahan tertinggi, tetapi kandungan karbon tertinggi berada di kelas Dinophyceae. Zonasi riverin, transisi, dan lakustrin memiliki status kesuburan yang sama, tetapi memiliki komposisi dan komunitas fitoplankton yang berbeda. Berdasarkan hasil penelitian, diperoleh kandungan karbon fitoplankton relatif tinggi di zona riverin dan lakustrin, dan rendah di zona transisi.

Abstract

Organic matter entering through the inlet and activities in the Koto Panjang Reservoir body is feared to be the main source of nutrient contribution in the form of nitrogen (N) and phosphate (P) for reservoir waters. Nutrients N and P are utilised by phytoplankton in the photosynthesis process. If this condition continues, it is feared that it will affect water quality (blooming algae) which has an impact on aquatic biota. This study aims to determine the type and abundance of phytoplankton along with the distribution of chlorophyll a in reservoir waters. This study used descriptive, qualitative and quantitative methods and analysed the distribution of chlorophyll a using surfer software. Based on the results of the study, it is known that water quality is relatively good with temperatures ranging from 26-310C, brightness ranging from 0.69-1.96 m, dissolved oxygen (DO) is 5.60-6.80 mg/L and turbidity is 1-6 NTU. The results showed that phytoplankton composition was composed of 5 classes consisting of Euglenophyceae (1 species), Cyanophyceae (3 species), Conjugatophyceae or Zygnematophyceae (4 species), Chlorophyceae (4 species) and Bacillariophyceae (10 species). The dominating class in the reservoir zonation is different. In the riverine zone the Bacillariophyceae class dominates by 60.06%, in the transition zone the Cyanophyceae class by 91.60% and in the lacustrine zone the dominating class is Conjugatophyceae or Zygnematophyceae by 78.69%. Phytoplankton abundance ranged from 166.5-2,193 sell/m3. The highest abundance was located in the lacustrine zone and the lowest abundance in the riverine zone. The distribution of chlorophyll a in Koto Panjang Reservoir is varied, the highest distribution is located in the transition zone to the lacustrine zone.

Abstract

The genus Cyperus is widely recognized as decorative flora. Empirically, Cyperus plants have been utilized to treat wounds, inflammation, and digestive disorders. While the genus is reported to exhibit antioxidant properties, scientific data regarding Cyperus involucratus remains limited. This research aimed to identify antioxidant compounds in C. involucratus using Ultra-High-Performance Liquid Chromatography-High Resolution Mass Spectrometry (UHPLC-HRMS). The C. involucratus methanolic extract was obtained through maceration using a 70% methanol solvent. Separation was performed using a UHPLC gradient system with a flow rate of 0.3 mL/min , while compound identification was conducted using a Quadrupole-Orbitrap MS detector in positive mode. The radical scavenging activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The analysis identified 175 metabolites within the methanolic extract. Based on mzCloud library matching with confidence scores of 97.4–100%, 12 primary bioactive compounds were identified: oleamide, α -linolenic acid, kaempferol, scutellarin, hexadecanamide, 1-linoleoyl glycerol, 1-stearoy-rac-lglycerol, adenine, adenosine, L-tyrosine, stearamide and nootkatone. The extract possessed a moderate radical scavenger with an IC50 value of 57.94 μg/mL. These findings provide a scientific foundation for further investigation of C. involucratus as a potential natural antioxidant, although further in vivo studies are required to validate its broader pharmacological outcomes.

Abstract

Zooplankton, particularly Daphnia sp., play a key role in aquatic food webs and exhibit strong life‑history plasticity in response to predation risk mediated by chemical cues (kairomones). Aquatic macrophytes such as water spinach (Ipomoea aquatica) are often assumed to provide refuge that may mitigate these effects. This study examined the influence of catfish (Clarias sp.) kairomones and the potential moderating role of I. aquatica on reproduction and survival of Daphnia sp. using an individual‑based bioassay with a randomized block design. Four treatments were applied: control, I. aquatica, kairomones, and kairomones + I. aquatica, observed in 15 days. Parameters measured included neonate number, age at first and second reproduction (AFR, ASR), Second Clutch/First Clutch ratio (C2/C1 ratio), and mortality. Kairomone exposure significantly reduced first‑clutch offspring production and delayed AFR, and induced compensatory reproduction in the second clutch, reflected by the highest C2/C1 ratios (K = 2.30; H = 2.11). Mortality was also highest in kairomone treatments (>42%). The presence of I. aquatica did not significantly mitigate kairomone effects and was associated with increased mortality relative to the control. These results indicate that chemical predator cues dominate over physical shelter in shaping Daphnia sp. life‑history strategies, with important implications for zooplankton dynamics in vegetated freshwater ecosystems.

Abstract

A financial feasibility analysis in mariculture activities is necessary to ensure the business can provide economic benefits and operate sustainably. The Dampier Strait Conservation Area has the potential to develop seaweed and pearl oyster cultivation businesses. However, as a conservation area, its utilization must consider environmental carrying capacity. This study aims to assess the financial feasibility of seaweed and pearl oyster cultivation in the Dampier Strait Conservation Area as a basis for optimal, environmentally friendly business planning that provides economic benefits for the local community. Financial feasibility is measured using a cost-benefit analysis method. The first step is to determine the efficiency of component use and cost structure in the aquaculture business planning scheme. The results of the cost and benefit calculations are used to determine the capacity for developing the aquaculture business, which includes an assessment of several aspects of future investment. Based on the results of the cost-benefit analysis, the marine aquaculture business for both commodities is feasible for development, having met business feasibility requirements based on the comparison of cost and benefit values, the percentage of profit, the rate of return on assets, the difference and comparison between expenses and revenues, and the payback period. All stages of the analysis have been able to produce comprehensive results to achieve optimal and sustainable utilization of the area through the development of mariculture activities. This has taken into account the continuity between environmental potential and human demands for utilizing ecosystem services in an integrated manner.
