Abstract

The study, in 2012, has successfully formulated with the MCDM for each allocation of  space in KKPD allotment (core areas, sustainable fisheries zone, used zone, and other zones). This weighting techniques need to be tested and  be implemented in identifying and designing the KKPD in the study area. This study aims to identify and map the biophysical conditions and the potential of coastal and marine natural resources in marine conservation area candidate, North Luwu Regency; to identify the areas suitable for the KKPD based on weighting technique with the MCDM method; and to evaluate potential candidates for marine protected areas in the coastal region. This study used a survey method to perform in  situ measurements of physico-chemical parameters, conducted a survey of coastal ecosystems using the transect method. The socio-economic data of coastal communities were collected using the questionnaire. The biophysical conditions and marine resources were analyzed using descriptive statistical methods. The results showed that the candidate region has a rich diversity  of coastal ecosystems, but the ecosystem, particularly seagrass beds and coral reefs have been in damaged category. Only the mangrove ecosystem that was still in a good condition category with moderate-to-heavy levels of density. There were 6 species of seagrasses and 6 species of mangroves and 71 species of reef fish. It was discovered 2 regions  corresponding to the allotment of the Core Zone, which is in the Region I and III with the total area of 654.22 hectares. For sustainable fisheries zone, Region  II and IV would be the first choice with the total area of 620.27 hectares. The Used Zone was identified in the Region V with total area of 480.66 hectares. The total area of the region was equal to 1755.15 hectares. Marine protected areas of was suggested to the protection of coastal ecosystems including mangroves, seagrass beds, and coral reefs and its associated biota, especially the protection of local feeding ground of several species (sea turtles and dugongs).

Abstract

Determination of the geochemical fractionation of metals is also important to identify sources of metal pollutants in waters, whether they originate from natural processes or originate from human activities. This study aims to analyze the potential availability of Pb metal in sediments for biota and analyze the relationship between sediment grain size and total organic matter with the geochemical characteristics of Pb metal. The research was carried out in the North Maluku Waters Region in March 2023. consisting of 4 stations namely Ternate Island (Bastiong Harbor and Waters around Pertamina Jambula), Tidore (PLTU Waters) and Halmahera (Waters around the NHM Gold Mining area). And each station consists of 3 points. Sample testing was carried out at the Chemical Oceanography Laboratory, Faculty of Maritime Affairs and Fisheries, Hasanuddin University. And metal analysis was carried out at the Agency for Standardization and Industrial Services Policy Testing Laboratory BBSP JIHPMM Makassar City. Metal concentrations in the sediment fraction were determined by the BCR Sequential Extraction method (Based on Sarkar et al., (2014) The results showed that the total fraction was unstable at station 1, 2 and 3 were higher than the non-labile fraction, while at station 4 it was found that the total non-labile fraction was higher than the labile fraction.

Abstract

Perairan pantai Kota Makassar, termasuk dua muara sungai yang mengapit, yaitu Sungai Jeneberang dan Sungai Tallo banyak mendapat inputan logam dari badan sungai dan dari daratan utama, berupa limbah industri dan limbah perkotaan.  Penelitian ini bertujuan untuk menentukan distribusi spasial konsentrasi Pb, Cd, Cu, dan Zn serta fraksi bioavailable di sedimen perairan pantai Kota Makassar. Penelitian dilakukan di wilayah perairan pantai Kota Makassar, mulai dari muara Sungai Jeneberang hingga muara Sungai Tallo. Pengukuran logam dilakukan pada sedimen berukuran < 63 μm. Spesiasi logam pada fraksi sedimen ditentukan dengan metode Community Bureau of Reference (BCR) Three-steps Sequential method yang menghasilkan fraksi exchangeable dan acid soluble, reducible, serta oxidisable. Interpolasi sebaran spasial logam di sedimen dilakukan dengan menggunakan teknik Sistem Informasi Geografis (SIG) yaitu block kriging (BK) dengan  program Arc View.  Sebaran logam sangat ditentukan oleh input atau sumber dari daratan dimana sebaran spasial logam Pb, Cd, Cu, dan Zn di sedimen meningkat ke arah utara pantai Kota Makassar.  Sebaran spasial fraksi 1 (terlarut dalam asam, acid reducible) logam Pb dan Cu tidak berbanding lurus dengan sebaran konsentrasi totalnya  di sedimen. Sedangkan sebaran spasial fraksi 1 logam Cd dan Zn berbanding lurus dengan sebaran konsentrasi totalnya di sedimen.
