“…It has been shown previously those vertical profiles of the metals in WFC and EFC showed differently, and no consistent correlation between metals and grain size. Commonly, the metal profiles in sediment are related to the environmental deposition and input of metals (Buccolieri et al, 2006;Duquesne et al, 2006 andSinolungan et al, 2008). This anomaly was very likely stimulated by the difference between two sampling locations in which EFC was located seawards direction making this location to be more exposed to seawater than WFC.…”

Semarang Flood Canals distinguished its merit to cope the flood, thus, the observation of sediment quality as one of environmental assessment is required. Those sediments hosted pollutants like heavy metals being a hazard to human. So, the aims of this study were to measure the concentration and to assess the sediment quality based on heavy metal in the flood canals. Responding to the objective, the sediment collection was carried out in April 2016. The collection core sediment samples were carried out up to 80 cm in depth and the sub-sample was collected within 5 cm interval. The laboratory analysis revealed the average concentrations of Cd, Cu, Fe, Ni, Pb, and Zn in the east flood canals were 0,1-0,43; 25,9-36,7; 40.933-76.942; 24,5-35,2; 5,8±13,4; 74,2±113,8 mg/kg dry, respectively. Meanwhile, the concentrations of Cd, Cu, Fe, Ni, Pb, and Zn in the west flood canals were 0,1-0,5; 25,6-59,5; 34.083-76.119; 24,3-33,2; 7,7±22,0; 75,5±173,4 mg/kg dry. East Flood Canal which hosted more intense anthropogenic activities was exhibiting higher metals concentration than West Flood Canal. Enrichment Factor (EF) was computed to assess sediment quality based on heavy metals and the result indicated no enrichment and minor enrichment of metals in the sediment except for Cd and Zn in east flood canal.

“…Secara umum, danau merupakan perairan umum daratan yang memiliki fungsi penting bagi pembangunan dan kehidupan manusia. Danau Tondano merupakan salah satu sumberdaya alam vital di Kabupaten Minahasa Provinsi Sulawesi Utara, yang memiliki berbagai peruntukkannya, antara lain: sebagai sumber air (air minum, lahan pertanian, budidaya ternak, perikanan), pariwisata dan sumber pembangkit tenaga listrik (Sinolungan, et al, 2008). Dengan adanya berbagai peruntukkan Danau Tondano yang diikuti dengan pertambahan jumlah penduduk, maka semakin bertambah pula kebutuhan masyarakat terhadap sumberdaya tersebut, sehingga terdapat berbagai permasalahan, antara lain: sedimentasi dan pendangkalan danau, yang terjadi karena adanya erosi lahan di daerah tangkapan air serta lahan sempadan danau yang terakumulasi oleh endapan/sedimen pada perairan danau (Wilar dan Mandagi, 2010).…”

Tondano Lake, one of vital natural resources at Minahasa Regency, North Sulawesi, has some functions and some problems, i.e.: sedimentation and lake shallowing. This research was conducted by using water hyacinth (Eichornia crassipes (Malt)) as compost/organic fertilizer and sediment of Tondano Lake as plant media for Packoy growth. This research has aimed to: 1) Test the composition of Tondano Lake sediment, 2) Test the composition of water hyacinth compost, and 3) Measure the growth of Pakcoy toward the given compost as a preliminary research (Pot Experiment). This was conducted: a) sediment sampling at the west part of Tondano Lake, b) sediment and compost analyses at Chemical and Soil Fertility Laboratory of Agriculture Faculty of Unsrat, c) planting Pakcoy in small pots with Group-Randomized Design for nine months in 2016. Results showed that, 1) sediment composition of Tondano Lake as the plant media has tested, 2) compost composition of water hyacinth has tested, and 3) Pakcoy growth toward the given compost as a preliminary research (Pot Experiment) has measured by height of plant, number of leaves, and freshedweight of crops, andso would applicable in further research due to the result of analyses was significantly different. ABSTRAKDanau Tondano merupakan salah satu sumberdaya alam vital di Kabupaten Minahasa Provinsi Sulawesi Utara, memiliki berbagai peruntukkannya dan terdapat berbagai permasalahan, antara lain: sedimentasi dan pendangkalan danau. Penelitian ini dilakukan dengan memanfaatkan tanaman eceng gondok (Eichornia crassipes (Malt)) sebagai kompos/pupuk organik dengan sedimen Danau Tondano sebagai media tanam bagi pertumbuhan tanaman Pakcoy.Penelitian ini bertujuan untuk: 1) Menguji komposisi sedimen Danau Tondano sebagai media tanam, 2) Menguji komposisi kompos dari tanaman eceng gondok, dan 3) Mengukur pertumbuhan tanaman Pakcoy terhadap pemberian kompos sebagai penanaman awal (Percobaan Pot). Penelitian ini dilaksanakan: a) sampling sedimen di bagian barat Danau Tondano, b) analisa sedimen dan kompos di Laboratorium Kimia dan Kesuburan Tanah Fakultas Pertanian Unsrat, c)penanaman tanaman Pakcoy ditanam di pot-pot kecil dengan Rancangan Acak Kelompok selama sembilan bulan di tahun 2016. Hasil penelitian menunjukkan bahwa, 1) komposisi sedimen Danau Tondano sebagai media tanam telah teruji, 2) komposisi kompos dari tanaman eceng gondok telah teruji, and 3) pertumbuhan tanaman Pakcoy terhadap pemberian kompos sebagai penanaman awal (Percobaan Pot) telah terukur melalui tinggi tanaman, jumlah daun dan berat segar tanaman sehingga penelitian ini dapat diaplikasikan lebih lanjut oleh karena hasil analisisnya berbeda nyata.

The purpose of this research was to determine the amount of waste in TPA Puuwatu and the volume of methane gas produced. It used a quantitative descriptive method with data obtained from related institutions, such as the Sanitation and Parks Office and the Central Statistics Agency. The survey location was TPA, which is a Final Waste Processing Site, Puuwatu in Kendari City.. The results showed that the average volume of waste from January to July 2018 was 5,278 m3, though the total was 32,667m3 with potential waste (Q) of 184.503,216 kg/day. The volume of methane gas produced was 15,360.3062 m3/day.
