Abstract

One of the efforts to support the development of coastal areas, is through mangrove management. Besides having a role in the economic development of coastal communities, mangrove also has role as mitigation of carbon emissions. This study aimed to provide an overview of the perceptions and participation of the community and order of stakeholders in the mangrove management at the mouth of Musi River. The research was conducted at Musi River estuary, Banyuasin Regency, South Sumatra Province. Meanwhile, the data of stakeholders perception were derived through respondents' interviews. The results showed that more than 90% of the community knew mangrove existence and function and agreed to participate in various mangrove management policies. An effort is needed so that all stakeholders become key players in mangrove management as carbon reserves at the mouth of the Musi River. Management recommendations for carbon reserves enhancement include empowerment and improvement of community knowledge, forest rehabilitation and land, development of agroforestry cultivation techniques, development of non-timber forests, also soil and water conservation.

Abstract

This study aims to inform the initial data on water quality around the PSDKU IPB Sukabumi campus before the campus was built. Surface water is represented by the upstream, middle and lower reaches of the Cibeureum River. Residents' well water which represents the location of the planned construction of the PSDKU IPB campus in Sukabumi City, namely Babakan Village. Surface water quality parameters that do not meet the quality standards are BOD, COD, Nitrite, and Total Phosphate, while in well water quality, the parameter that does not meet the quality standards is Manganese (Mn). The pollution index indicates that the surface water quality is generally lightly polluted. For surface water, exceeding the quality standards of several parameters can be related to domestic waste and runoff from agricultural areas. The high value of Manganese in well water is a common phenomenon, which describes the natural characteristics of well water.

Abstract

The research aimed to determine the vulnerability level of the Cikeas watershed in terms of socio-economic and institutional aspects. The primary data collection method used purposive and snowball sampling. Secondary data were obtained from the Environmental Agency (DLH), Ciliwung Cisadane River Basin Center (BBWS) and Central Statistics Agency (BPS). Data analysis used quantitative descriptive analysis based on the formulation of watershed level characterization system. The vulnerability level of the Cikeas watershed in social aspects (population density and traditional values) was very high (very vulnerable). Conservation behaviour was classified as not vulnerable and somewhat vulnerable. On the economic aspect, most sub-districts in the Cikeas watershed were classified as somewhat vulnerable. The dominant economic sector was in the form of services. In terms of the institutional aspect, it was classified as not vulnerable and somewhat vulnerable because there were formal and informal institutions that have played an active role in the Cikeas watershed conservation activities. Watershed problems were related to the community's concern for environmental management. Thus, the involvement of the community and other relevant stakeholders in the planning, formulation, implementation of watershed policies was indispensable to achieve sustainable watershed management.

Abstract

The Batang Arau River is the second longest river in the city of Padang (West Sumatra). Many anthropogenic activities can reduce water quality. This study aimed to determine the correlation water quality with the hydrological parameters of the Batang Arau River (2013-2020). The data taken is secondary data from several agencies in the city of Padang. Data analysed was secondary data from various institution in Padang. Simple Linear Regression between water quality parameters towards velocity and river discharge was applied. River discharge correlated with DO (r = 0.68), and velocity is very closely correlated with TDS (r = 0.82) in the rainy season. Meanwhile, very close correlation between discharge and TDS (r = 0.98) and velocity with DO (r = 0.95) in the dry season.

Abstract

Given the emergence of several new regulations in the environmental sector, stakeholders need to understand these regulations well. Therefore, this article aims to provide a practical understanding of the mechanism for compiling and evaluating environmental documents to obtain environmental approvals contained in a number of new regulations. The issuance of Government Regulation No. 22 of 2021 requires the issuance of several new Minister of Environment and Forestry Regulations. There are several new requirements that must be met in submitting an application for an environmental feasibility test, namely: Letter of direction for the preparation of environmental documents, Statement letter that the proposed activity is still in the planning stage (for new activity plans), Technical Approval, Initial approval related to the business/activity plan, Evidence of conformity of the location of the business/activity plan with the spatial plan. The authority to assess environmental documents is based on the authority to issue business permits and the establishment of a Feasibility Test Team (TUK) to replace the role of the EIA Assessment Commission (KPA).

Abstract

Jakarta Bay is an active area and receives pollution from the mainland through 13 river systems in DKI Jakarta. This waste enters Jakarta Bay through 13 rivers. This study compared the distribution of dissolved heavy metals in the West and East Monsoons of Jakarta Bay to understand the processes and sources of heavy metals. Sampling was carried out once in each zone, and sea water samples stored in HDPE (high-density polyethylene) bottles were taken to the laboratory for analysis using AAS (Atomic Absorption Spectrophotometry), with a measurement accuracy of 0.001 mg/L. GIS was used to map heavy metal parameters. The concentrations of heavy metals found were mercury (Hg) 0.0002 to 0.0005 mg/L, copper (Cu) 0.0062 to 0.0089 mg/L, lead (Pb) 0.006 to 0.007 mg/L, zinc (Zn) 0.0247 to 0.0334 mg/L, and nickel (Ni) 0.0044 to 0.0088 mg/L. In summary, the study shows that the physical-chemical conditions of Jakarta Bay significantly affect the distribution of dissolved heavy metals such as Hg, Cu, Pb, Zn and Ni.

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

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

Lamun memiliki fungsi ekologis penting sebagai penyerap karbon dioksida (CO2), yang dikategorikan sebagai bagian dari blue carbon atau karbon biru. Gas CO2 tersebut diserap oleh tumbuhan lamun dan dikonversi menjadi biomassa melalui proses fotosintesis. Estimasi cadangan karbon dalam biomassa lamun dapat dihitung melalui pendekatan kuantitatif yang melibatkan hubungan antara kerapatan tumbuhan, total biomassa, dan konsentrasi karbon dalam jaringan vegetatifnya. Penelitian ini dilakukan pada ekosistem lamun yang berada di wilayah perairan Desa Kahyapu dan Desa Kaana, Pulau Enggano, Provinsi Bengkulu. Pengumpulan data menggunakan metode purposive sampling dengan teknik transek kuadrat berukuran 1 m × 1 m, sedangkan analisis kandungan karbon dilakukan berdasarkan metode Walkey dan Black (1934). Tujuan utama dari penelitian ini adalah untuk menganalisis besaran cadangan karbon yang tersimpan pada biomassa lamun, baik pada komponen di atas substrat (daun) maupun di bawah substrat (akar dan rimpang). Hasil penelitian mengidentifikasi tiga spesies lamun, yaitu Enhalus acoroides, Thalassia hemprichii, dan Cymodocea spp. Di antara ketiganya, Enhalus acoroides menunjukkan nilai cadangan karbon tertinggi dengan rata-rata 50,75 g C/m2, diikuti oleh Thalassia hemprichii dengan rata-rata 17,53 g C/m2, dan Cymodocea spp. dengan rata-rata 2,99 g C/m2.
