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.

Abstract

The objective of the present study was to analyze the community structure of mangrove vegetation in Pidie District, Aceh Province and to plan its management strategies. The study was conducted from August to November 2014 in three subdistricts namely Batee, Kota Sigli, and Simpang Tiga. A total of three sampling stations were determined purposively at every subdistrict where every station has two substations and every substation has three sampling plots of 10 m x 10 m. In addition, a total of 297 respondents as representative of the fish farmer, fishermen, and other stakeholders were interviewed to collect data to plan the management strategies using the SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis. The results showed that there were six species of mangrove found in Pidie District namely Avicennia alba, A. officinalis, A. marina, Rhizophora mucronata, R. apiculata and Sonneratia alba. For seedlings and saplings categories can be classified into very good condition, except in Kecamatan Batee  where S. alba for seedlings was classified into moderate damage and the saplings was in highly damaged condition. The mangrove of trees category was classified into heavily damaged condition. The management strategies of mangrove ecosystem in Kabupaten Pidie can be done by maximizing the function of mangrove ecosystems by replanting the species of mangrove that match with the habitat for their life so that can produce the specific functions; improve the role of government and society in controlling and monitoring the mangrove ecosystems; and establish the local regulations about the management of mangrove ecosystems in Kabupaten Pidie.Penelitian ini bertujuan untuk menganalisis struktur komunitas vegetasi mangrove dan menetapkan strategi pengelolaannya di Kabupaten Pidie Provinsi Aceh.

Abstract

Sembilan Island was one of the 17 islands located in the East Coast of North Sumatra. This island is surrounded by mangrove with varying thickness and density. Information on the identification and potential of mangrove in this island already reported but limited to a narrow area. Information about the value and status of mangrove ecology in this island have not been written, so it was needed to carry out for a study of mangrove ecological analysis. This information could be used later as a reference in sustainable mangrove management. The objective of the study was to determine the value and ecological status of mangroves. The research was conducted in September 2015. The data were collected at 9 sampling points namely; 4 points in the east, 2 points in the south and 3 points in the west part of the study areas. The spot check method was used in the study. The results showed that there were 28 species of mangrove belonging to 13 families. It's divided into  26 species of true mangrove and two species of associated mangroves. Mangrove’s zonation was Avicennia/Sonneratia on the front and ferns (A. Aureum and A. speciosum) in the section near the mainland. Mangrove thickness reached 134 - 1683 m. The density of mangrove was 333 - 4601 individuals/ha with the cover area of 2522 - 5810 cm2/ha. The results of the importance index value of mangrove showed that A. marina has a great influence and role in the community of mangrove vegetation, especially in the eastern part. Therefore, the mangrove in Sembilan Island was categorized into damage to good condition. The good category was recorded in the western part of the island, while the damaged category was found in the east part of the island.Pulau Sembilan merupakan satu diantara 17 pulau yang terdapat di wilayah Pantai Timur Sumatera Utara. Hampir sepanjang pantai di Pulau Sembilan di tumbuhi oleh mangrove dengan ketebalan yang bervariasi. Informasi tentang identifikasi dan potensi mangrove di Pulau Sembilan sudah ada dilaporkan, namun terbatas pada areal yang sempit. Informasi tentang nilai dan status ekologi mangrove di Pulau Sembilan belum dilaporkan, sehingga perlu adanya kajian tentang analisis ekologi mangrove. Informasi ini nantinya dapat dijadikan sebagai acuan dalam pengelolaan mangrove yang berkelanjutan. Penelitian ini bertujuan untuk mengetahui nilai dan status ekologis mangrove di Pulau Sembilan. Lokasi penelitian dibagi menjadi tiga area dengan 9 titik pengamatan yaitu timur 4 titik, selatan 2 titik, dan barat 3 titik. Penelitian dilaksanakan pada September 2015. Pengambilan contoh mangrove, dilakukan dengan menggunakan metode spot check. Hasil penelitian didapatkan bahwa jenis mangrove yang sebanyak 28 jenis dari 13 famili yang terdiri dari 26 jenis mangrove sejati dan 2 jenis mangrove ikutan. Zonasi mangrove di Pulau Sembilan yaitu, Avicennia/Sonneratia pada bagian depan dan paku-pakuan (A. Aureum dan A. speciosum) pada bagian yang dekat daratan. Ketebalan mangrove mencapai 134 - 1683 m. Kerapatan mangrove yang ditemukan mencapai 333 - 4601 ind/ha. Penutupan mangrove mencapai 2522 - 5810 cm2/ha. Hasil analisis nilai penting jenis mangrove di Pulau Sembilan menunjukkan bahwa A. marina memiliki pengaruh dan peran yang besar dalam komunitas vegetasi mangrove, terutama pada bagian timur. Mangrove di Pulau Sembilan termasuk kategori rusak - baik. Kategori baik pada bagian barat dan rusak pada bagian timur.
