Abstract

The fish processing and marketing group (poklahsar) in the Gili Matra Marine Protected Area has received intervention from the central government through Bappenas in the COREMAP-CTI III program. This intervention involves improving human resource capacity and providing grants for fish processing equipment. However, the limited duration of the program has resulted in suboptimal assistance in utilizing the donated fish processing equipment. Therefore, the involvement of universities in assisting the community is deemed necessary. This assistance activity aims to inform and educate the poklahsar about the use of fish processing equipment, particularly machines, to enhance production capacity in the Gili Matra Marine Protected Area. The assistance activities were carried out in July 2023 at the respective production locations of each poklahsar. The educational method for adults in this assistance activity involves lectures and hands-on practical training. The outcome of this assistance activity is an increased understanding and knowledge among poklahsar in the Gili Matra Marine Protected Area regarding the functions and uses of various machine-based fish processing equipment. Additionally, it was identified that some obstacles hinder optimizing machine-based equipment utilization, including a lack of understanding in using such equipment and limited market demand for processed fish products. In conclusion, the poklahsar have diverse views on using machine-based equipment, enabling them to optimize the use of such equipment despite the limited demand for processed fish products.

Abstract

Coliform bacteria are a group of bacteria that originate from human and animal feces in large numbers, so they are often used as indicators of food and water quality. This study aims to determine the condition of the aquatic environment based on biological indicators such as the abundance of coliform bacteria in river water and wells in Hu'u sub-district, Dompu district. Data on coliform bacteria and water quality were sourced from PT STM based on the survey results of PT Intertek and PT Sucofindo in several rivers and wells in 2021. The results of data analysis show that most rivers have coliform bacteria density values exceeding the quality standards set by the Ministry of Environment and Ministry of Health. This is probably because many residents and cattle still dispose of their feces in the river.

Abstract

Coral reefs are under pressure from climate change and various factors, putting them at risk of a decline in resilience. This heightened vulnerability increases the likelihood of reaching a tipping point with the next shock or stressor. Identifying early warning indicators for tipping points is crucial for proactive coral reef management. Therefore, this study aims to comprehend the coral reef health parameters considered important and feasible for collection by local stakeholders, as well as identify factors facilitating the implementation of a community-based monitoring and early warning system in a fishers-dominated community. The approach used was Participatory Action Research. The results reveal twelve priority parameters deemed necessary by the local community and feasible for collection by local stakeholders, including the local community, university, and non-governmental organization. The identified parameters are: coral bleaching, visibility, temperature, pH, dissolved oxygen, salinity, current, coral percent cover, fish community, macroalgal canopy cover and composition, benthic composition, and plankton. Interpretive structural model and MICMAC analysis show nine enabling factors supporting the development of a community-led coral reef health monitoring and early warning system. These factors include team motivation, training and team capacity, connection with government, connection with university, facilitation by NGOs, supporting regulations, operational funds, access to equipment, and operation and maintenance of equipment. Team motivation stands out as the most influential factor, with strong driving power and dependence, making it crucial to manage as actions on it will have ripple effects on other factors.

Abstract

Cempi Bay is an important water area with a rich and diverse ecosystem. One crucial component of marine ecosystem that plays a major role in maintaining the balance of the marine environment is seagrass. The objective of this research is to provide critical insights into the dynamics of seagrass populations in Cempi Bay and offer an overview of the broader coastal ecosystem's condition. The research, conducted in June-July 2021 at 5 research stations, employed the transect method. At each data collection point, three transect lines were created perpendicular to the coastline. The distance between transect lines was 100 m, and each transect consisted of 10 quadrants measuring 1x1 m with a 5 m distance for each quadrant. Four seagrass species were identified: Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Cymodocea serrulata. These species were found on sand substrates, with the highest total density and percentage cover observed at Station 5 (1135.22 ind/m2 and 40.74%). The results highlight the necessity for routine monitoring, mapping, and further research to comprehend seagrass population dynamics and support effective conservation policies. Implementation of recovery strategies, water quality management, and continued research support is imperative to ensure the sustainability of seagrass ecosystems and marine resources in Cempi Bay.

Abstract

Mangroves play a crucial role in maintaining environmental balance, including wave attenuation, preventing erosion, providing habitat for various species, and storing carbon to mitigate climate change. However, mangrove ecosystems are currently facing serious degradation threats due to human activities and climate change, necessitating protective measures, rehabilitation, and active community participation to ensure their preservation. This community service initiative aims to conserve mangrove ecosystems through nursery activities (nursery) and mangrove planting (out-planting) in potential areas not yet populated by mangroves in Siung Village, Sekotong, West Lombok. The nursery activities include techniques for collecting seedlings from the wild, selecting and sorting healthy seedlings, placing them in planting media, and caring for the seedlings. Meanwhile, the out-planting activities involve planting the seedlings in the wild and monitoring the planted mangroves to ensure their survival. Over approximately two months, this project has produced 3,200 mangrove seedlings of Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa, and Ceriops tagal species, with a survival rate of 87.5%. As for the out-planting activities, 2,700 mangrove seedlings have been successfully planted in areas near the nursery site. Challenges encountered during seedling collection and care include tidal fluctuations, the presence of pests and predators. In the out-planting activities, ongoing monitoring and maintenance are required to maintain a high survival rate for the seedlings planted in the wild.

Abstract

Mangrove ecosystems are a vital form of aquatic ecosystem that significantly contribute to maintaining carbon balance in the atmosphere and support climate change mitigation efforts. Their ability to absorb and store carbon in both biomass and soil makes them among the most effective carbon sinks. This study aims to estimate the carbon storage of mangrove stands in the Gita Nada Mangrove Area, Sekotong, West Lombok. The research was conducted at three stations: Station 1 (Berambang), Station 2 (Siung), and Station 3 (Bangko-Bangko). Data collection involved a 10 x 10 meter transect, where species and diameter at breast height (DBH) data were recorded. Allometric equations were then applied to calculate biomass and carbon reserve values. The results identified four mangrove species: Rhizophora mucronata, R. stylosa, R. apiculata, and Avicennia marina. The average mangrove density at each station fell within the moderate to dense category, with values ranging from 1000 to 4666.66 individuals per hectare. The estimated carbon stocks of the mangrove stands were as follows: Station 1 had 149.33 tons per hectare, Station 2 had 28.38 tons per hectare, and Station 3 had 476.36 tons per hectare. These findings indicate significant differences in estimated carbon stock values across the stations. Overall, the results of this study provide crucial information to support conservation and restoration efforts for mangrove ecosystems in West Lombok, enhancing understanding of the role of mangroves in mitigating climate change.

Abstract

Pantai Pandanan yang terletak di Desa Malaka kecamatan Pemenang merupakan salah satu destinasi wisata pantai yang terletak di Lombok Utara. Pantai Pandanan memililiki ekosistem terumbu karang yang mendukung keanekaragaman hayati lokal dan merupakan bagian penting dari ekosistem laut setempat. Penelitian ini bertujuan untuk membandingkan pertumbuhan karang Acropora yang ditransplantasi menggunakan dua jenis media, yaitu blokmars dan meja, di perairan Pantai Pandanan, Lombok Utara. Penelitian dilakukan selama empat bulan, dari Mei hingga Agustus 2024, dengan pengamatan pertumbuhan panjang karang setiap bulan. Hasil penelitian menunjukkan bahwa karang yang ditransplantasi pada media blokmars mengalami pertumbuhan yang lebih signifikan dibandingkan dengan media meja. Rata-rata pertumbuhan karang pada media blokmars meningkat lebih cepat pada awal periode transplantasi, sedangkan pada media meja pertumbuhannya lebih lambat. Media blokmars terbukti lebih stabil dan efektif dalam mendukung pertumbuhan karang, karena memiliki struktur yang memfasilitasi perlengketan dan penyediaan nutrisi yang optimal. Berdasarkan hasil ini, media blokmars direkomendasikan sebagai pilihan yang lebih baik untuk kegiatan rehabilitasi terumbu karang
