Abstract

Until now there has not been a centralized Wastewater Treatment Plant (WWTP) in IPB, even though there are wastewater treatments in several locations that are scattered in the campus area. Various activities on the Dramaga IPB campus have the potential to produce wastewater, such as laboratory activities, especially chemical and biological laboratories, canteens, offices, and dormitories. The existence of scattered laboratories requires a centralized and integrated WWTP. For this reason, mapping of wastewater distribution is needed to arrange the location of the wastewater treatment plant, within the campus. Interviews with the perpetrators of activities, measurement of wastewater quality, and sampling, were carried out at the work units producing wastewater on the campus of IPB. The distribution of wastewater was grouped according to the location of the work units producing waste and identified the types of waste produced (B3-dangerous and toxic and non-B3), then presented in a map. The map was used as a reference in determining the location of wastewater treatment plants. The results showed that each work unit contributes organic waste that was not too different, the source of inorganic and B3 wastewater distribution followed the location of the laboratory which was also quite scattered in the Dramaga IPB campus area. Based on the distribution of available waste, the presence of wastewater in the campus environment of IPB was divided into two regional groups. Therefore, the location of the wastewater treatment plant was directed at two locations, namely on the Northeast side (IPAL I) and the West side (IPAL II) of IPB campus.

Abstract

Waduk Jatigede merupakan perairan daratan tergenang yang terbentuk dari pembendungan sungai Cimanuk. Waduk Jatigede, sebagaimana waduk umunnya, secara horizontal terbagi atas tiga wilayah, yaitu riverin, transisi, dan lakustrin. Perbedaan karakteristik setiap zona juga berdampak pada komposisi dan komunitas fitoplankton, status trofik, dan kandungan karbon. Penelitian ini bertujuan untuk mengalkulasi seberapa besar kandungan karbon pada fitoplankton di perairan Waduk Jatigede pada setiap zona dengan komposisi dan komunitas fitoplankton pada status trofik tertentu. Stasiun penelitian dipilih menggunakan purposive sampling dengan pemilihan stasiun berdasarkan zona dalam waduk, yaitu riverin, transisi, dan lakustrin. Analisis status trofik dan kandungan karbon digunakan untuk mengetahui kondisi dan keberadaan karbon di Waduk Jatiged. Status trofik Waduk Jatigede berdasarkan Indeks Nygaard dan TSI (Tropic State Index) dikategorikan ke dalam tingkat kesuburan eutrofik. Jenis-jenis dari Kelas Cyanophyceae memiliki kelimpahan tertinggi, tetapi kandungan karbon tertinggi berada di kelas Dinophyceae. Zonasi riverin, transisi, dan lakustrin memiliki status kesuburan yang sama, tetapi memiliki komposisi dan komunitas fitoplankton yang berbeda. Berdasarkan hasil penelitian, diperoleh kandungan karbon fitoplankton relatif tinggi di zona riverin dan lakustrin, dan rendah di zona transisi.

Abstract

Terumbu karang membutuhkan waktu yang lama untuk pulih dan rentan terhadap kerusakan. Penelitian ini bertujuan untuk menganalisis variabilitas spasial tutupan terumbu karang berdasarkan kategori pemanfaatan yang berbeda di Perairan Kepulauan Seribu Utara. Penelitian ini dilaksanakan pada bulan Agustus 2022 di enam stasiun pengambilan sampel di Perairan Kepulauan Seribu Utara. Pengambilan data tutupan karang diestimasi menggunakan metode Line Intercept Transect, sampel kualitas air yang diambil meliputi parameter kecerahan, nitrat, oksigen terlarut, pH, dan salinitas. Kategori pemanfaatan yang berbeda antar-stasiun pengambilan sampel tidak berpengaruh nyata terhadap besar persen tutupan karang hidup, kecuali pada stasiun yang berkategori dilindungi. Penyebab utama yang mempengaruhi nilai persen tutupan terumbu karang antar-stasiun pengambilan sampel diduga karena kerusakan fisik akibat benturan secara langsung dari aktivitas manusia, seperti kegiatan penangkapan, pariwisata, dan transportasi. Tutupan karang tertinggi dengan kategori baik terdapat pada Area Perlindungan Laut, sementara tutupan karang terendah dengan kategori rusak terdapat di Barat Pulau Pramuka sebagai stasiun yang paling terpengaruh oleh aktivitas manusia.

Abstract

Waduk Jatigede yang berdekatan dengan daerah pemukiman dan kegiatan pertanian berpotensi menerima buangan limbah, yang diduga juga mengandung bahan pencemar nitrogen. Peningkatan kandungan nitrogen secara kontinyu dapat memberikan dampak buruk, seperti penurunan kualitas air dan terjadinya eutrofikasi. Analisis daya tampung beban nitrogen di Waduk Jatigede, Jawa Barat ini dilakukan berdasarkan data primer yang dikumpulkan. Pengambilan contoh air dan pengumpulan data perairan Waduk Jatigede dilakukan terhadap enam stasiun pengamatan dan dua sungai utama inlet Waduk Jatigede. Selanjutnya dilakukan penentuan beban nitrogen dari sungai (inlet) dan dalam waduk, sedimentasi nitrogen, serta daya tampung beban nitrogen. Beban nitrogen di Waduk Jatigede sebesar 24.374 ton telah melebihi batas maksimum menurut baku mutu perairan, sebesar 1.739 ton. Sementara, daya tampung beban nitrogen maksimal sesuai dengan baku mutu perairan di Waduk Jatigede adalah sebesar 595 ton. tahun-1. Dapat disimpulkan bahwa Waduk Jatigede sudah tidak mampu lagi menampung beban nitrogen yang masuk.

Abstract

Crown Golf merupakan danau hias dangkal yang berlokasi di Perumahan Cluster Crown Golf, Pantai Indah Kapuk, Jakarta Utara. Telah terjadinya eutrofukasi pada perairan tersebut menyebabkan berkurangnya fungsi danau hias. Tujuan penelitian ini adalah untuk menganalisis hubungan kandungan P yang terdapat di air dan sedimen di Danau Crown Golf. Analisis contoh air dan sedimen dilakukan di Laboratorium Produktivitas dan Lingkungan Perairan, Departemen Manajemen Sumberdaya Perairan, FPIK IPB University. Aplikasi STELLA 9.0.2 digunakan untuk simulasi pengelolaan pada Danau Hias Crown Golf. Berdasarkan hasil, terdapat 5 dari 13 parameter kualitas air yang tidak sesuai dengan baku mutu kelas II pada PP No. 82 Tahun 2001. Kandungan P di air selama pengamatan cenderung naik, sedangkan pada sedimen hasilnya cenderung turun. Berdasarkan hasil simulasi, jika dilakukan skenario pengelolaan dengan penggunaan empat buah kincir air selama enam jam pengoperasian menyebabkan kondisi P di air danau cenderung stabil. Keberadaan P di air tidak berkaitan erat dengan keberadaan P di sedimen, keberadaan P di sedimen dipengaruhi oleh DO dan suhu kolom air bawah.

Abstract

Danau Ebony merupakan danau hias buatan yang di sekitarnya terdapat aktivitas domestik yang menghasilkan limbah yang dapat mempengaruhi kualitas perairan dan biota yang ada didalamnya, salah satunya zooplankton. Danau Ebony dijadikan objek studi untuk melihat keterkaitan antara komunitas zooplankton dengan kualitas air. Penelitian dilakukan pada bulan April-Agustus 2014 pada 5 stasiun pengambilan contoh dengan interval satu bulan. Berdasarkan hasil, komunitas zooplankton di perairan Danau Ebony terdiri atas kelompok Rotifera (7 genera), Crustacea (3 genera), dan Protozoa (2 genera). Kelimpahan tertinggi adalah genus Brachionus dari kelompok Rotifera. Kelompok Rotifera berkorelasi negatif kuat dengan TSS, kekeruhan, ammonia dan berkorelasi positif kuat dengan pH. Hal ini menandakan tingginya TSS, kekeruhan, ammonia diikuti oleh rendahnya kelimpahan Rotifera, sedangkan tingginya pH diikuti oleh tingginya kelimpahan Rotifera. Kelompok Protozoa berkorelasi positif kuat dengan TSS dan berkorelasi negatif kuat dengan suhu.
