Proporsi ruang terbuka hijau patut diperhitungkan karena perannya sebagai pembentuk dan keseimbangan struktur daerah. Menurut UUD No. 26 Tahun 2007 secara khusus mengamanatkan perlunya penyediaan dan pemanfaatan ruang terbuka hijau dengan proporsi luasnya ditetapkan paling sedikit 30 % dari luas wilayah suatu daerah. Adapun permasalahan yang terjadi menurut Kepala Dinas Lingkungan Hidup Kabupaten Kubu Raya pada tahun 2019 luasan ruang terbuka hijau di Kubu Raya belum mencapai 10% dari total luas wilayah. Berdasarkan proyeksi dari tahun 2015 – 2020 Kecamatan Sungai Raya tidak bisa menunjang kebutuhan daya dukung lingkungan (oksigen) karena ketersediaan RTH Publik tidak dapat diimbangi dengan kebutuhan laju pertumbuhan penduduk, kendaraan bermotor, kebun sawit, dan permukiman. Kecenderungan menurunnya kualitas dan kuantitas Ruang Terbuka Hijau (RTH) mengharuskan tata ulang dan penghitungan ulang terhadap luasan RTH.ABSTRACTThe role of green open space is currently less than optimal, the proportion of green open space should be taken into account because of it’s role in shaping and balancing the regional structure. According to the UUD No. 26 Tahun 2007 specifically mandates the need for the utilization of green open space, the proportion of which is set at least 30% of the total area. problems in 2019 the area of Green Open Space in Kubu Raya has not reached 10% of the total area, based on projections from 2015 – 2020 Kecamatan Sungai Raya cannot support the needs of environmental carrying capacity (oxygen) because the availability of public green open space cannot be matched with the need for population growth, motorized vehicles, oil palm plantations, and settlements. The tendency to decrease the quality and quantity of Green Open Space (RTH) requires a reorganization and recalculation of the area of green open space.","PeriodicalId":34848,"journal":{"name":"Rekayasa Hijau Jurnal Teknologi Ramah Lingkungan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48890686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bau tersebut berasal dari limbah atau sisa pengolahan ikan yang tidak dikelola dengan baik. Salah satu gas penyebab bau tersebut adalah gas hidrogen sulfida (H2S) yang dihasilkan dari proses penguraian protein didalam limbah ikan. Limbah ikan yang dibuang begitu saja dapat menjadikan bibit penyakit bagi masyarakat yang disebabkan dari gas H2S karena terjadi proses penguraian protein didalam limbah ikan. Penelitian ini bertujuan untuk menguji kemampuan karbon aktif dari tempurung nipah dalam menjerap gas H2S yang terkandung dalam limbah ikan dalam besaran penurunan konsentrasi H2S 􁈺Δ𝐶􁈻 dan dengan variabel berupa jumlah adsorben 20, 30, dan 40 gram. Gas H2S dari limbah ikan diadsorpsi menggunakan karbon aktif dari tempurung buah nipah teraktivasi NaOH dalam suatu rangkaian alat adsorpsi dengan kolom berisi karbon aktif dan dilengkapi dengan kolom larutan penjerap gas limbah ikan yakni larutan kadmium asetat di bagian sebelum dam setelah kolom adsorpsi. Penentuan konsentrasi gas H2S yang terjerap dalam karbon aktif dilakukan dengan metode titrimetri yakni titrasi iodometri pada larutan kadmium asetat. Hasil penelitian menunjukkan penurunan kadar H2S pada limbah ikan dengan jumlah adsorben 20, 30, dan 40 gram masing-masing adalah 33,497 ppm (71,15%), 33,452 ppm (71,05%), dan 34,381 ppm (73,03%). ABSTRACTThe fish processing industry plays an important role in the Cilacap economy, but on the other hand this also contributes negatively to environmental air quality because it produces a disturbing odor. The smell comes from waste or fish processing residue that is not managed properly. One of the gases that causes the odor is hydrogen sulfide (H2S) gas which is produced from protein decomposition process in fish waste. Fish waste that is thrown away can cause disease for the community caused by H2S gas because there is a process of protein decomposition in fish waste. This study aims to test the ability of activated carbon from nipah shells to absorb H2S gas contained in fish waste in the parameter amount of decreasing H2S concentration (ΔC) and with variables amount of adsorbent which are 20, 30, and 40 grams. H2S gas from fish waste is adsorbed using activated carbon from NaOH activated nipah shell in a series of adsorption devices with a column containing activated carbon and equipped with a column of fish waste gas absorbing solution, namely cadmium acetate solution in the section before and after the adsorption column. Determination of the concentration of H2S gas adsorbed in activated carbon was by the titrimetric method, namely iodometric titration in cadmium acetate solution. The results showed a decrease in H2S levels in fish waste with adsorbents of 20, 30, and 40 grams respectively 33,497 ppm (71.15%), 33,452 ppm (71.0","PeriodicalId":34848,"journal":{"name":"Rekayasa Hijau Jurnal Teknologi Ramah Lingkungan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44877226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
