Penelitian dilakukan dalam skala laboratorium selama 28 hari (500 gram) secara buatan. Bioremediasi tanah tercemar limbah oli menggunakan metode biostimulasi dengan pupuk NPK dan pupuk kompos sebagai nutrien. Variasi yang dilakukan adalah pemberian jenis pupuk sebagai nutrien kedalam tanah tercemar (kombinasi pupuk NPK 5% + pupuk kompos 5%, pupuk NPK 10%, pupuk kompos 10% dan sampel kontrol) dan waktu pengujian sampel (hari ke-0, ke-7, ke-14, ke-21 dan hari ke-28). Parameter yang diuji adalah kadar TPH. Hasil penelitian menunjukkan bahwa penurunan terbaik rata-rata di hari ke 14-hari ke 21 yaitu dengan rata-rata penurunan sebesar 8,25%, penambahan nutrisi pupuk NPK 22% + pupuk kompos 19% memberi hasil terbaik dalam penelitian ini yaitu penurunan kadar TPH sebesar 36%.","PeriodicalId":429294,"journal":{"name":"Jurnal Lingkungan dan Sumberdaya Alam (JURNALIS)","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126140313","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}

Detergent waste treatment needs to be done to minimize this impact, one of which is the adsorption method using coconut shell charcoal. The purpose of this study was to measure the efficiency of reducing the levels of COD, BOD, TSS and pH of detergent wastewater using the adsorption method by coconut shell charcoal. This study used a completely randomized design (CRD) with 1 independent variable factor (charcoal thickness) consisting of 4 levels of treatment, namely control (without charcoal), treatment 1 (100cm thick charcoal), treatment 2 (110cm thick charcoal), treatment 3 (120cm thick charcoal), each treatment was repeated three times. The test parameters (bound variable) in this study were COD, BOD, pH, and TSS. The results showed that the A120 treatment had the best reduction efficiency in reducing COD, BOD, TSS and pH levels to 197 mg/L (75%), 101 mg/L (86%), 35 mg/L (69%) and 7 mg/L. However, this grade value does not meet the quality standards of Permen LHK 68/2016. Based on U Mann Whitney's statistical analysis, it is known that there is no significant difference in the thickness variation of coconut shell charcoal on decreasing levels of COD, BOD, TSS and pH.","PeriodicalId":429294,"journal":{"name":"Jurnal Lingkungan dan Sumberdaya Alam (JURNALIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122108441","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}

Selama ini penggunaan flokulan dalam pengolahan limbah masih didominasi oleh flokulan sintesis, yang terbukti berdampak negatif terhadap lingkungan. Dengan ditemukannya Bioflokulan-DYT berpeluang menjadi alternatif pengganti flokulan sintetis. Potensi tersebut telah dibuktikan pada penelitian sebelumnya, yang menunjukkan kecenderungan penurunan nilai hantaran molar Bioflokulan-DYT seiring dengan kenaikan nilai konsentrasinya. Untuk memperkuat penelitian sebelumnya, maka dilakukan penelitian lanjutan terkait sifat fisik dari senyawa aktif Bioflokulan-DYT. Salah satunya yang dilakukan pada penelitian ini, yaitu menganalisis kemampuan senyawa aktif Bioflokulan-DYT dengan ion logam yang diukur dari harga konduktivitasnya. Larutan kristal senyawa aktif Bioflokulan-DYT direaksikan dengan larutan ion logam yaitu Ni(NO3)2, Co(NO3)2, dan Ca(NO3)2. Kemudian masing-masing campuran tersebut diuji nilai konduktivitasnya menggunakan konduktometer. Hasil pengukuran dan perhitungan konduktivitas campuran senyawa aktif Bioflokulan-DYT dengan larutan ion logam menunjukkan terjadinya interaksi. Pengaruh panambahan larutan Bioflokulan-DYT pada konsentrasi rendah (250 ppm, 500 ppm dan 750 ppm), mengakibatkan nilai hantaran molar pengukuran lebih tinggi dibandingkan dengan nilai hantaran molar perhitungan. Kondisi ini mengindikasikan senyawa aktif Bioflokulan-DYT dapat berperan sebagai polielektrolit. Sedangkan pengaruh panambahan larutan Bioflokulan-DYT pada konsentrasi tinggi (1000 ppm, 1250 ppm, 1500 dan 1750 ppm), menyebabkan nilai hantaran molar pengukuran lebih rendah dibandingkan dengan nilai hantaran molar perhitungan. Kondisi ini mengindikasikan bahwa senyawa aktif Bioflokulan-DYT berperan sebagai ligan yang dapat berinteraksi dalam pembentukan senyawa kompleks dengan ion logam.
