Abstract

Fruit peel waste was one of carbohydrate feedstock for producing bioethanol. The research main purpose was analyzing the impact of yeast mass addition in fermentation process of pineapple and papaya peels mixture (PPPM) for making of bioethanol. The procedure was carried out by adding 10 grams of glucose for each treatment, the yeast Saccharomyces cerevisiae mass varied from 1 to 4 % w/v, and the fermentation time were 24, 48, 72 and 96 hours at temperature 30 0C. The initial sugar containment was tested by Brix refractometer and the bioethanol composition was characterized using Gas Chromatography-Mass Spectrometry. The initial sugar content of the PPPM starter was range from 3 – 5 %. By addition of yeast weight (1 - 4% w/v), the comparison of bioethanol yield were in range 2 to 5% using hydrometer alcohol and in the range of 3,013–3,403% while using GC-MS. In conclusion, the sugar content of PPPM substrate and yeast starter percentage have significant effect on bioethanol earning

Abstract

Limbah kulit durian yang menumpuk akan menjadi sumber pencemar jika tidak diberdayakan dengan benar. Salah satu upaya untuk memberdayakan limbah kulit durian adalah mengolahnya menjadi produk bioetanol. Kulit durian mengandung 5% elemen zat tepung dan lignin yang mengandung 50-60% selulosa. Selulosa merupakan karbohidrat utama yang disintesis oleh tanaman dan hampir 60% penyusun struktur. Karbohidrat adalah bahan dasar dalam pembuatan etanol. Penelitian ini menggunakan limbah kulit durian untuk produksi bioetanol melalui proses fermentasi dengan penambahan Saccharomyces cerevisiae (ragi). Penggunaan enzim alphaamilase dan enzim glukoamilase untuk pemecahan selulosa dalam limbah kulit durian sehingga produksi bioetanol semakin meningkat. Sampel limbah kulit durian ini menunjukkan hasil dimana pH 4.5  dan suhu 35°C merupakan pH dan suhu fermentasi sampel limbah kulit durian yang memiliki persentase maksimum produksi bioetanol. Hal ini membuktikan bahwa konsentrasi etanol dalam air secara bertahap meningkat seiring dengan meningkatnya pH dan mencapai persentase maksimum produksi bioetanol pada pH 4,5 dan menurun pada pH 5. Melalui penelitian ini diharapkan mampu mengurangi pencemaran lingkungan dari penumpukan limbah kulit durian dan menjadi bahan bakar alternatif baru produksi bioetanol.

Abstract

Abstrak -  Sungai Krueng Daroy merupakan perairan yang terletak di kawasan kabupaten Aceh Besar dan Kota Banda Aceh. Hulu sungai Krueng Daroy berada di kawasan pegunungan Mata Ie, air sungai Krueng Daroy digunakan sebagai sumber pembuangan dari penduduk berupa limbah rumah tangga, dan sampah. Penelitian ini bertujuan untuk mengetahui kemampuan biofilter sarang tawon untuk menurunkan kadar parameter pH, TDS, DO, TSS, BOD dan COD. Sampel diambil dari air sungai Krueng Daroy sebanyak tiga titik sampel yaitu: Jembatan Peuniti, Jembatan Geuce dan Jembatan Keutapang. Hasil penelitan menunjukkan bahwa kadar pH terendah pada titik Peuniti dan titik Keutapang yaitu 7. Parameter TDS nilai terendah pada titik Peuniti yaitu 98,0. Parameter DO terendah pada titik Keutapang yaitu 1,7. Parameter TSS terendah pada titik Geuce dan titik Keutapang yaitu 3,4, parameter BOD terendah pada titik Geuce yaitu 1,00 dan parameter COD nilai terendah terletak pada titik Peuniti dan titik Geuce yaitu 11,04. Setelah perlakuan dengan kombinasi biofilter terjadi penurunan parameter kualitas air sungai pada semua parameter kecuali COD yang belum memenuhi Peraturan Pemerintah RI. No. 82 Tahun 2001 kelas 1, untuk itu diperlukan pengolahan menggunakan media biofilter lainya dalam mengolah air sungai, agar semua baku mutu dapat diturunkan.Kata kunci : Air sungai, biofilter media plastik dan kualitas air.                         Abstract –  Krueng Daroy River is a water located in the district of Aceh Besar and Banda Aceh City. The headwaters of the Krueng Daroy river are in the Mata Ie mountain area, the water of the Krueng Daroy river is used as a source of disposal from residents in the form of household waste and garbage. This study aims to determine the ability of a honeycomb biofilter to reduce levels of parameters pH, TDS, DO, TSS, BOD and COD. Samples were taken from the water of the Krueng Daroy river as many as three sample points, namely: Peuniti Bridge, Geuce Bridge and Keutapang Bridge. The results showed that the lowest pH level at the Peuniti point and the Keutapang point was 7. The lowest value TDS parameter at the Peuniti point was 98.0. The lowest DO parameter at the Keutapang point is 1.7. The lowest TSS parameter is at the Geuce point and the Keutapang point is 3.4, the lowest BOD parameter is at the Geuce point is 1.00 and the lowest COD parameter is at the Peuniti point and the Geuce point is 11.04. After treatment with a combination of biofilters, there was a decrease in river water quality parameters in all parameters except COD which did not meet the Indonesian Government Regulations. No. 82 of 2001 class 1, it is necessary to process using other biofilter media in treating river water, so that all quality standards can be lowered.­Keywords: River water, plastic media biofilters and water quality

Abstract

Increase in science and technology development today has spurred environmental pollution in water, soil and air. Water pollution caused by the impact of industrial development must be controlled as quickly as possible. The study aimed to investigate the effect of Eichhornia crassipes plants at given metal concentrations. The Eichhornia crassipes plant was used as an observation material with varying concentrations of metal (Cr, Hg, and Pb). The method used in this study was Randomised Block Design (RBD) and continued with Duncan's Multiple Range Test analysis, or better known as the DMRT test. The study observations showed that the increase in Eichhornia crassipes seedlings was 3cm, 2cm and 2cm, respectively with the recorded concentrations of 20%, 40%, 60%, and 80%. Meanwhile, the leachate concentrations of 20%, 40%, 60%, and 80% could also increase the roots of Eichhornia crassipes plants by 3.5cm, 1.5cm and 1cm, respectively. However, the leaf growth of Eichhornia crassipes plants at concentrations of 20% and 40% recorded as much as three and two leaves only. Additionally, it can be noted that at leachate concentrations of 20% and 40%, there was an increase in the number of Eichhornia crassipes leaf petals during observation. Overall results showed that low concentrations could increase the Eichhornia crassipes plants. This was evident in the statistical test analysis, where the leachate concentration in the Eichhornia crassipes plant affected the overall test results.
