Abstract

Dunaliella salina is a green microalgae that has the ability to produce β-carotene used in various fields, such as food supplements, natural colorant, antioxidants, anti-cancer, and anti-aging. D. salina is capable of producing large amounts of carotenoids under stressful conditions, including light and nutrient. Light is the main factor that stimulate the production of carotenoid pigments and media composition plays an important role for growth, biomass, and β-carotene production. The accumulation of β-carotene in microalgae is closely related to the type and quality of light and the composition of the culture media. This study aimed to determine the production of β-carotene in microalgae D. salina using LEDs and different culture media to select the best culture conditions for producing high value compounds. The results showed that D. salina cultured using red LED light and technical Walne media was able to produce β-carotene with the highest amount of 767,499 mg/100 g. In blue LED light and Walne Pro-analysis media, the β-carotene content was 380,522 mg/100 g, while the ZA+NPK media has the lowest value. In this study, Walne Pro-analysis media became the best culture medium for D. salina. Therefore, natural sources of β-carotene can be obtained from D. salina, so it could reduce the use of synthetic carotene in meeting global demand.

Abstract

Macroalgae or known as seaweed is one of the potential resources and is responsible for primary productivity in marine waters. Macroalgae plays an important role in marine ecosystems, provides food, oxygen, and habitat for several types of marine biota. Moreover, macroalgae have been reported as renewable resources in marine environment and widely used in various fields. The biodiversity and abundance of macroalgae are strongly influenced by aquatic environmental factors. Lemukutan Island is the largest inhabited island located in Bengkayang Regency, West Kalimantan and has the potential natural resources, including macroalgae. This Island can become a center for producing macroalgae that can be used to meet food needs both locally and domestically. The main objective of this study were to determine the community structure of macroalgae and the condition of the environmental physico-chemical parameters. The sampling locations were carried out in-situ at three stations and the determination of the sampling site was done by purposive random sampling method, by selecting an area based on the presence of macroalgae. The sampling of macroalgae was carried out using a quadratic transect with size of 10x10 m2 and the water quality parameters were measured using the AZ 8603 of WQC instrument. The study found 6 genera of macroalgae, such as Caulerpa, Halimeda, Padina, Turbinaria, Sargassum, and Gracillaria. Among the identified macroalgae, Phaeophyceae have the highest per cent contribution (50%), and Padina had the highest abundance (29.84 ind/m2). Lemukutan Island waters had a moderate level of diversity, high macroalgae uniformity, and dominance index in the low category. The aquaatic environmental factors influenced the abundance of macroalgae in Lemukutan Island waters.

Abstract

A common problem faced by coastal communities is the lack of clean water. This issue also occurs in the coastal area of Sungai Nibung Village, Teluk Pakedai District, Kubu Raya Regency. The community relies on dug well water; however, this water is yellowish, murky, and has an iron odor. This activity, in Community Service (PKM), aims to collect data on the condition of water and existing clean water fasilities and infrastructure, and offer treatment solutions that consider the current situation. The method was carried out through field surveys, raw water sampling, simple water testing (pH, salinity, and coagulation-flocculation tests), and observation of clean water supporting facilities. High levels of in the water can be reduced through coagulation-flocculation using soda ash and PAC to precipitate the iron. If the sedimentation stage is skipped, the workload of the filters in te available facilities becomes heavier. One applicable solution for the community is to add aeration and sedimentation tanks to oxidize and precipitate the iron.

Abstract

Mangrove forests provide essential ecological and economic services; however, increasing human activities and natural disturbances have led to widespread degradation, highlighting the need for effective rehabilitation efforts. This study evaluated the success of mangrove rehabilitation in the concession area of PT Kandelia Alam, Kubu Raya Regency, Indonesia, using indicators of survival rate, plant height, leaf number, and environmental conditions. Data were collected under three site conditions (flooded, flowing-water, and unflooded areas) across two observation stations, each consisting of three measurement plots. Each plot measured 20 × 50 m and contained a 20 × 20 m subplot representing 100 individual plants, with observations conducted up to T₀ + 9. The results indicated that rehabilitation success at Stations I and II was moderate, with survival rates of 74.33% and 72.17%, respectively. Average plant heights were 50.60 cm at Station I and 53.66 cm at Station II, with an average of five leaves per individual at both stations. The Rhizophora  mucronata and Bruguiera gymnorrhiza species exhibited better adaptability in flowing-water and unflooded areas, whereas the Rhizophora apiculata species showed lower survival rates, particularly under flooded conditions. Environmental parameters at both stations were generally within suitable ranges for mangrove growth, including salinity of approximately 22 ppt, water temperature of 28°C, water pH of 7, soil temperature of 30–31°C, soil pH of 5.5, and substrates dominated by silty clay and silt. These findings suggest that while survival rates indicate moderate rehabilitation success, vegetative growth remains suboptimal, emphasizing the importance of site–species matching, hydrological suitability, and early-stage maintenance to enhance long-term mangrove rehabilitation outcomes.

Abstract

Mangrove ecosystems play a crucial role as coastal blue-carbon reservoirs, yet widespread land-use conversion has led to substantial degradation and carbon loss in many regions. This study estimates sediment carbon storage in mangrove ecosystems in Purun Kecil Village, Mempawah Regency, West Kalimantan, Indonesia, and identifies sediment factors influencing carbon retention. The research was conducted from June to August 2025, with sediment samples collected at a depth of 0–30 cm across natural mangroves, inactive fishponds, and coconut plantations. Organic carbon was analyzed using the Loss on Ignition (LOI) method, accompanied by measurements of bulk density, soil texture, pH, moisture, and salinity. The results show that natural mangroves stored the highest sediment carbon stock (614.7 Mg C/ha), followed by inactive fishponds (472.0 Mg C/ha) and coconut plantations (392.9 Mg C/ha). One-way ANOVA confirmed significant differences in sediment carbon stocks among land-use types (p < 0.001), and Tukey’s HSD post-hoc analysis indicated that all land-use categories differed significantly. Higher carbon storage in natural mangroves was associated with lower bulk density and finer sediment texture, which promote carbon stabilization under anaerobic conditions. These findings demonstrate that land-use conversion from mangroves to aquaculture and agriculture substantially reduces sediment carbon reserves and degrades soil quality. The study highlights the importance of mangrove conservation and restoration as effective nature-based solutions for climate change mitigation and coastal ecosystem management.
