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

Lamun merupakan tanaman air yang memiliki bunga dan kemampuan beradaptasi untuk hidup dan tumbuh di laut seperti tanaman terestrial. Kelangsungan hidup lamun sangat dipengaruhi oleh parameter fisik dan kimia perairan, seperti pH, suhu, dan salinitas. Intergovernmental Panel on Climate Change (IPCC) melaporkan pada akhir abad 21, CO2 di atmosfer selalu meningkat seiring dengan perkembangan industri. Peningkatan CO2 di atmosfer menyebabkan terjadinya asidifikasi laut sehingga dapat mengubah struktur kimia dan pH air laut. Rendahnya pH air laut berpengaruh terhadap fisiologi tumbuhan seperti terhambatnya proses fotosintesis dan pertumbuhan. Tujuan penelitian ini adalah untuk menguji pengaruh pH terhadap pertumbuhan dan laju fotosintesis lamun Thalassia hemprichii. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 3 perlakuan yaitu kontrol (8,10-8,50), pH sedang (7,76-8,00) dan pH rendah (7,50-7,75) dalam 5 ulangan. Hasil penelitian menunjukkan bahwa laju pertumbuhan, laju fotosintesis dan kandungan klorofil memiliki nilai lebih besar pada kontrol dibandingkan dengan perlakuan pada pH sedang dan rendah. Hasil uji ANOVA tidak signifikan untuk semua variabel perlakuan dan memiliki dampak negatif pada kelangsungan hidup lamun.

Abstract

Penggunaan bahan bakar fosil yang terus berlangsung akan meningkatkan konsentrasi karbondioksida (CO2) di atmosfer. Asidifikasi laut terjadi akibat CO2 yang berada di atmosfer berdifusi ke lautan. Lautan mampu menyerap CO2 di atmosfer sebanyak 35 % lebih yang menyebabkan terjadinya penurunan pH laut. Lamun Cymodocea rotundata merupakan salah satu jenis lamun yang banyak ditemukan tumbuh di perairan tropis. Keadaan ini menimbulkan kekhawatiran tentang kemungkinan terjadinya dampak pada pertumbuhan lamun C. rotundata. Penelitian ini bertujuan untuk menganalisis kandungan nitrat, fosfat dan kalium dan pertumbuhan lamun C. rotundata yang meliputi pertumbuhan daun, rhizoma, dan akar C. rotundata terhadap perbedaan pH. Penelitian menggunakan metode eksperimen dengan rancangan acak lengkap menggunakan tabel acak. Sebanycak 15 toples dengan ukuran diameter 20 cm dan tinggi 25 cm digunakan dengan 3 perlakuan, masing-masing perlakuan 5 kali pengulangan. Hasil uji regresi linier menunjukkan pH berpengaruh terhadap konsentrasi nitrat, dan berpengaruh kuat terhadap konsentrasi fosfat dan kalium. Laju pertumbuhan daun lamun C. rotundata tertinggi pada kontrol berkisar antara 0,50–1,29 mm/hari sedangkan yang terendah pada pH rendah berikisar 0,07–0,73 mm/hari. Laju pertumbuhan rizhoma lamun secara horizontal dan vertikal tertinggi pada pH rendah sedangkan yang terendah pada pH kontrol. Laju pertumbuhan akar lamun tertinggi pada pH rendah berkisar antara 0,20–0,90 mm/hari. sedangkan yang terendah pada kontrol berkisar antara 0,13–0,43 mm/hari. pH juga memengaruhi laju pertumbuhan daun, rhizoma dan akar lamun C. rotundata. Semakin rendah pH maka laju pertumbuhan daun juga semakin rendah, berbeda dengan rhizoma dan akar semakin rendah pH maka semakin tinggi laju pertumbuhan.

Abstract

Studi ini menilai keberhasilan Amdalnet menggunakan Model Keberhasilan Sistem Informasi DeLone dan McLean, dengan fokus pada enam dimensi: kualitas sistem, kualitas informasi, kualitas layanan, kegunaan, kepuasan pengguna, dan manfaat bersih. Survei online terstruktur dilakukan dengan 125 pengguna konsultan, pengulas, dan administrator yang menggunakan skala Likert dengan lima poin. Pemodelan Persamaan Struktural Kuadrat Terkecil Parsial digunakan untuk menganalisis data (PLS-SEM). Lima dari delapan hipotesis didukung. Khususnya, kualitas informasi tidak secara signifikan memengaruhi kepuasan pengguna atau penggunaan sistem, dan kepuasan pengguna tidak berdampak signifikan pada manfaat bersih. Temuan ini menunjukkan bahwa keterlibatan pengguna dalam platform digital wajib seperti Amdalnet lebih didorong oleh kepatuhan daripada nilai yang dirasakan. Studi ini menyoroti perlunya desain berorientasi pengguna dalam sistem informasi peraturan untuk meningkatkan kinerja dan legitimasi dalam tata kelola lingkungan.

Abstract

The coastal areas of Karawang Regency are at risk of being affected by oil spills originating from oil pipelines leaking. The purpose of this research is to develop an environmental sensitivity index based on the assessment standards of the National Oceanic and Atmospheric Administration, with research locations in the Karawang Coast. The results showed that the resources in the Karawang coastal area that sensitive to oil spills are shoreline type of mangrove  with a total length of 34.76 km of shoreline; consist of dense mangrove forest with an area of 173.14 ha; capture fisheries with 6,832 fishermen with a production of 9,319.38 tons/year; and aquaculture involving 5,643 fishing households with a production of 43,389.45 tons/year. The environmental sensitivity index value was concluded as very sensitive for mangrove beaches, mangrove forests in all locations and aquaculture in the Tirtajaya & Batujaya areas, while the capture fisheries and the capture aquaculture were concluded as sensitive. The environmental sensitivity index maps of the three themes indicated that the socio-economic component is the most sensitive component compared to other components. Specifically, the socio-economic components that were the most sensitive to the impact of oil contamination were aquaculture and capture fisheries areas.

Abstract

The cultivation of Alabio ducks (Anas Platyrynchos Borneo) so far is still natural and only involves one parameter; furthermore, each location has different characteristics. The hierarchical structure constructed has a ranking of importance as an alternative option for ducks' development in peatland ecosystems. This research aims to formulate a strategy for duck production in the Hulu Sungai Utara Regency. AHP (Analytical Hierarchy Process) method in this study is used to structure the decision-making flow from goals and alternatives and weigh the variables. Data collection was carried out with duck farming experts from academia, farmer groups, and policymakers. This study found that the availability of feed, both sago (0.254) and bran (0.218), is a significant component from an ecological perspective. Distance to market (0.307) and hatchery location (0.287) is an economic variable. The social part consists of distance from the settlement (0.443) and labor availability (0.247). Meanwhile, the availability of feed (0.282), hatchery technology (0.269), and Mina ducks (0.251) are the development strategies for duck cultivation in swamp areas, and economic stimulus (0.93) is the final contributor.

Abstract

Small islands face unique sustainability challenges in domestic wastewater management (DWM) due to limited resources, confined space, and high ecological vulnerability, yet comprehensive multi-dimensional assessments remain scarce. This study addresses this gap through a multi-aspect assessment of the DWM system on Tidung Besar Island, Indonesia, integrating technical, institutional, environmental, and social dimensions in a densely populated tourism-based small island. An exploratory-descriptive approach was employed, combining field observations, stakeholder interviews, questionnaires, and secondary data analysis from March 2024 to August 2025. Data were analyzed through triangulation methods, descriptive statistics, and qualitative synthesis. The study reveals a critical paradox that despite strong community acceptance and established infrastructure comprising four wastewater treatment plants serving 831 house connections, the system faces severe environmental challenge. Ammonia and total coliform exceed quality standards by up to 163 and 137 times. Technical challenges include overcapacity in high-demand zones, equipment failures, and incomplete service coverage, while institutional monitoring remains weak. Socially, most residents lack wastewater knowledge yet report high satisfaction based on visible improvements. This reveals that community acceptance alone cannot serve as a reliable indicator of system success. The study also demonstrates that small island wastewater management requires integrated solutions addressing interconnected challenge across all dimensions simultaneously.

Abstract

Waste pollution into the Citarum River (main water source of Jatiluhur Reservoir) was dominated by the manufacturing industry sector (textile, chemical, metal, pharmaceutical). Industrial was the most common contributor to heavy metal waste. Heavy metal contamination into waters will cause any problems, one of which was the emergence of various diseases both short and long term. Based on the issues, the study of heavy metal contamination and also water quality parameter conditions in the Jatiluhur Reservoir was necessary. The heavy metals (Cu, Zn, Hg, Pb, Cd) contents were determined using the X-Ray Fluorescence (XRF) Spectrometry method (for sediment) and Atomic Absorption Spectrometry (AAS) method (for water). The other water quality parameters were analyzed using the methods from the Indonesian National Standard (SNI). Furthermore, the data were compared to the Canadian Sediment Quality Guidelines (for heavy metal in sediment) and water quality standards from Government Regulation of the Republic of Indonesia Number 82 of 2001 (Class 3) (for water quality parameters). Concerning the discussion, Jatiluhur Reservoir was divided into three zones i.e. the inlet area, main inundation area, and outlet area. Conditions in the sedimentary layer, mercury (Hg) have accumulated throughout the Jatiluhur Reservoir area with conditions exceeding the maximum limit, while Cu metal tends to accumulate in the inlet area with conditions exceeding the minimum limit. For other heavy metals, exceed the minimum limit at some locations, but more results were below that. Although all heavy metals have not been detected in water, this was a warning that the presence of heavy metals in sediments can potentially dissolve into the water, the most extreme thing that can happen was upwelling. If this happens, the heavy metals can be contained excessively in water, harmful to and possibly consumed by aquatic biota and human. Considering these conditions, the biota that was most likely to be exposed was benthic organisms. In general, the water quality parameters in Jatiluhur Reservoir meet the quality standards. Only ammonia that does not meet the quality standards for sensitive fish life, regarding the massively of aquaculture activity in this reservoir.

Abstract

This study aims to analyze garbage waste data by day in a week at the Cituis Fish Landing Base (PPI Cituis), identify the causes of waste issues, and provide recommendations for waste management and handling. The research was conducted over two weeks of observation. Data were collected through waste characterization, total and average garbage waste volume measurements, the number of waste containers, and waste type composition from several source points. The results show that waste volume tends to increase at the end of the month, on weekends, and during holidays, following higher visitor numbers and fishing activities. Inorganic waste, especially plastic was the most dominant type across all port zones. The 3 kg container representing the harbor area had the highest percentage of waste bins compared with the 4 kg and 10 kg containers. Proper waste management is necessary to minimize pollution impacts at PPI Cituis and the surrounding environment. Recommended actions include improving waste facilities, strengthening governance and regulations, and enhancing community awareness and participation.
