Abstract

Coastal areas have an important role and have high natural resources that can be utilized for human life. Over time, the increase in population is directly proportional to the activities and utilization of coastal areas, which puts great pressure on coastal areas. One of the pressures that occur in coastal areas is heavy pollution. This research aims to see the distribution of heavy metals especially Cd, Cu and Pb in the coastal areas of Jakarta Bay and Semarang Bay and to see the differences in heavy metal content from the two gulfs. The data used in this study is secondary data, which consists of data on heavy metals, current velocity, pH and water temperature. The period of data used in this research are from 2016 to 2019, The method used in this study is the GIS method with descriptive analysis. The comparison of concentrations from two bays shows a higher mean of concentration value of heavy metals cadmium (Cd) in Semarang Bay (2016, 2017, 2019) and heavy metals of copper (Cu) in Jakarta Bay (2016 and 2018). Meanwhile, the concentration value of heavy metal lead (Pb) was higher in Jakarta Bay (2016, 2017, 2018), yet in 2019, the two locations have the same concentration value of heavy metal lead (Pb). Keywords:Coastal areaDistributionHeavy metalsJakarta BaySemarang Bay

The Siak River used for bathing, washing, dumping industrial palm oil, plantation, domestic waste, and port so it has an impact on water quality changing. This study analyzed the water quality and distribution spatial physical and chemical parameters the river around in Pekanbaru city, using Principal Component Analysis (PCA), this study used laboratory in situ and ex situ water quality measurement instruments. Water sampling each station done three times in two weeks during October to November 2019. The results obtained from this study shows the water quality of these 6 stations in the category of bad and the water quality from headwaters to downstream river influenced by organic parameter as a dominant pollutant. The correlation of water quality characteristic was 74.4% main factor 1 (F1) 47.4% and main factor 2 (F2) 26.7% with main characteristics fecal coliform, phosphate, and nitrate. Grouping these characteristics through a dendrogram showed three levels of relationship based on the characteristic parameter. The first group stands for station 1,2, and 4 have higher brightness and Dissolved oxygen (DO) parameters than other stations. The second group stands for stations 3 and 5 that have relatively high in parameter phosphate and nitrate. The third group is station 6 (river estuary) which results in shows high of fecal coliform proportional to pollution. The study can be concluded that three groups heavily contaminated. Each group has different parameters that show influence upland and waters activities.Keywords: Distribution of spatial, The quality of water, Siak River, Physical and Chemical Parameters, PCA ABSTRAKSungai Siak merupakan salah satu sungai terbesar di Provinsi Riau dan terdalam di Indonesia, dengan kedalaman sekitar 20-30 meter dan panjang 300 kilometer. Sungai siak masih dimanfaatkan oleh masyarakat sebagai sarana Mandi Cuci Kakus (MCK), tempat buangan limbah industri kelapa sawit, perkebunan, rumah tangga dan pelabuhan, sehingga berdampak pada perubahan kualitas perairan. Penelitian dilakukan untuk menganalisa kualitas dan distribusi spasial karateristik fisik-kimia perairan Sungai Siak di sekitar Kota Pekanbaru, dengan menggunakan Principal Component Analysis (PCA). Kajian menggunakan instrument pengukuran kualitas air in situ dan ex situ di laboratorium. Pengambilan sampel air pada masing-masing stasiun dilakukan sebanyak tiga kali setiap dua minggu selama bulan Oktober hingga November 2019. Hasil yang diperoleh dari kajian ini adalah kualitas air di keenam stasiun masuk dalam katagori buruk dan mengalami penurunan kualitas dari hulu ke hilir yang disebabkan bahan organik. Korelasi karakteristik kualitas air sebesar 74,3%, faktor utama 1 (F1)  47,4% dan faktor utama 2 (F2) 26,7% dengan penciri utama fecal coliform, fosfat dan nitrat. Pengelompokan stasiun pada dendogram klarifikasi hierarki menunjukkan adanya tiga tingkat hubungan kekerabatan berdasarkan parameter pencirinya. Kelompok satu terdiri dari stasiun 1, 2 dan 4 memiliki hasil relatif tinggi pada parameter kecerahan dan oksigen terlarut (DO) dibandingkan dengan stasiun lainnya. Kelompok dua terdiri dari stasiun 3 dan 5 memiliki hasil relatif tinggi pada paramter nitrat dan fosfat dibandingkan dengan stasiun lainnya. Kelompok tiga adalah stasiun 6 (muara sungai sail) dengan parameter fecal coliform relatif tinggi yang berbanding lurus dengan tingkat pencemarannya. Berdasarkan hasil kajian dapat disimpulkan bahwa tiga kelompok sama-sama tercemar berat, namun masing-masing kelompok memiliki perbedaan parameter pencirinya yang memperlihatkan pengaruh berbagai aktifitas di darat maupun di perairan itu sendiri.Kata kunci: Distribusi spasial, Kualitas air, Sungai Siak, Parameter fisika dan kimia, PCA

Abstract

It is important to maintain a healthy marine ecosystem to support eco-friendly and sustainable fishery development. Implementation of Ocean Health Index (OHI) started globally in 2012, and it has been strongly recommended to be conducted at all levels: locally, nationally, and regionally. Indonesia has modified OHI for its national assessment, which its called Indeks Kesehatan Laut Indonesia (IKLI). IKLI has been estimated since 2020 and introduction applied at the sub-national level. This study is an attempt to implement IKLI in Maluku province with the main objective is to estimate score of a partial IKLI, based on clean waters (goal no. 9) and biodiversity (goal no. 10). Samples were taken from Ambon and Baguala Bays between June and September 2022. For clean water goals, the parameters used were concentration of phosphate, nitrate, silicate, dissolved oxygen (DO), pH, and the number of ports that implemented green principles. The parameters of water quality of silicate, DO and pH in those two bays are within the range of government-mandated standards, except for nitrate and phosphate concentrations which are not. For the biodiversity goal, the parameters used are the species composition of mangrove, seagrass, fish, and coral. The IKLI biodiversity score was low due to the high level of human activity pressure at the two selected study sites. This study demonstrates the applicability of the IKLI in a partial analysis, and its usefulness in highlighting existing data and knowledge gaps. The study suggests that a comprehensive IKLI assessment should be conducted in Maluku Province. Meanwhile to improve the national-level IKLI assessment, actions should prioritize improving water quality management, expanding marine protected areas, and monitoring coastal ecosystems, especially those heavily affected by human activities.KeywordsArchipelagonutrientOHIIKLI Maluku

Abstract

This study aimed to examine the influences of the Indian Ocean Dipole (IOD) on rainfall in three districts in South Aceh. The analysis was undertaken using Dipole Mode Index (DMI) data and five years of rainfall (2016 to 2020) in West Labuhan Haji, Tapak Tuan, and Bakongan areas. This research employed a correlation analysis and the Principal Component Analysis, followed by Cluster Analysis to investigate the relationship between IOD and rainfall at the study location. The negative IOD occurred in 2016, and the positive IOD occurred in 2017, 2018, 2019, and 2020. The strongest positive DMI was in October 2019 (1.123˚C), while the strongest negative DMI was in July 2016 (0.661˚C). Generally, the sub-districts of West Labuhan Haji, Tapak Tuan, and Bakongan always have high rainfall. The highest rainfall in West Labuhan Haji was recorded in January 2017 (1014 mm/month), in Tapak Tuan in November 2017 (1073 mm/month), and in Bakongan in July 2020 (605 mm/month). The correlation between DMI and rainfall in the three locations shows different findings. Although it was very small, the IOD affected the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. In West Labuhan Haji, the highest correlation was in lag 1 (0.188); in Tapak Tuan, the highest correlation was in lag 2 (0.156), while in Bakongan, the highest correlation was in lag 2 (-0.191). The correlations in these three locations are considered weak. Thus, the IOD is not the main factor affecting the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. As South Aceh is located in windward, the orographic effect may influence high rainfall in this region.Keywords:DMIRainfallPrincipal component AnalysisWest Labuhan HajiTapak TuanBakongan

Abstract

Chlorella sp. is a single-celled microalga that mostly grows in marine waters. Chlorella sp. can grow in heavy polluted waters and therefore it has potency as a bioremediation agent. This study aimed was to analyze the effect of coal on the growth of Chlorella sp. in plant isolation media and the quality of water in plant isolation media for Chlorella sp. The complete randomized design with 4 treatments of coal concentration was used in this study. Four concentration concentrations were tested namely, 0 ppt, 1 ppt, 3 ppt and 5 ppt. The results revealed that coal with different concentrations gave no significant effect on the growth of Chlorella sp. (p 0.05). The density among the concentrations of 0 ppt, 1 ppt, 3 ppt and 5 ppt were not significantly different. In addition, the coal concentration gave no significant effect on temperature, salinity and potential hydrogen (pH) (p0.05). The Chlorella sp. can grow in the polluted water by coal, and therefore this alga can be used as potential organisms for bioremediation of coal waste.Chlorella sp. merupakan mikroalga bersel satu yang banyak tumbuh di perairan laut. Chlorella sp. dapat tumbuh di perairan yang tercemar berat sehingga berpotensi sebagai bioremediator. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi batubara terhadap pertumbuhan Chlorella sp. dan kualitas air pada media kultur Chlorella sp. Metode yang digunakan dalam penelitian ini adalah metode eksperimen skala laboratorium. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan 4 perlakuan konsentrasi batubara 0 ppt, 1 ppt, 3 ppt dan 5 ppt. Hasil penelitian menunjukkan bahwa batubara dengan konsentrasi yang berbeda tidak berpengaruh nyata terhadap laju pertumbuhan Chlorella sp (P0,05). Kepadatan antara konsentrasi 0 ppt, 1 ppt, 3 ppt dan 5 ppt tidak terlalu jauh berbeda. Konsentrasi batubara juga tidak berpengaruh nyata terhadap parameter suhu, salinitas dan derajat keasaman (pH) (p0,05). Chlorella sp. dapat tumbuh pada lingkungan yang tercemar oleh batubara, sehingga dapat dipakai sebagai organisme yang berpotensi untuk bioremediasi batubara.
