Abstract

Kelor (Moringa oleifera) is a kind of bush plant, which has a number of application potential, started from the leaf till the root. The seeds can produce 4-(alpha-L-rhamnosyloxy)benzyl isothiocyanate compound which can bind Cu(II). Besides, the seed also contains protein with cysteine and methionine components, which can bind Cu(II) from S-H group. In this research, copper adsorption by horse radish seed was measured, using complete powdered seeds (with epidermis skin part) and incomplete seeds (without epidermis). Two sizes of the powdered seed of 35/80 and 80/115 mesh sizes were applied. The initial concentrations of Cu(II) were 0; 0,25; 1; 5; 10 mg/L. The Cu(II) concentrations were analyzed using Atomic Absorption Spectrophotometer. In the batch process, the removal efficiency of Cu(II) was up to 97,07 % at initial concentration of 10 mg/L, using the incomplete seeds of 80/115 mesh size. In a continuous process with a flowrate of 0,5065 ml/minute Cu(II) removal was up to 96,2 %, and the adsorption capacity was 0,000149 mg adsorbate/mg adsorbant.

Abstract

The municipal solid waste (MSW) generation rate in Kediri was 697,768 m3 per day. The operation period of Kediri’s final disposal site (FDS) is 3-4 years. This condition provides an idea to excavate the FDS as an effort of rehabilitation, and to evaluate the fine material quality as compost. Four sampling sites were selected in the study area: site I (1 m, 3 years old), site II (2 m, 3 years old), site III (1 m, 1 year old), and site IV (2 m, 1 year old). Each sample was separated, air dried, and sieved. The highest fine material component (66,5%) was found in sampling site II. The colour of this fine material was brownish black and the odor was like soil. Characteristics of compost from all sampling sites met the compost quality standard according to SNI 19-7030-2004. Some parameters; however, exceeded the standards. These parameters werer volatile solid (> 80%), carbon (45-47%), C/N ratio (33 – 40), and faecal coli (>1000 MPN/gr). Therefore, the fine material from Kediri’s FDS could not be used as compost. The compost quality was best in FDS age of more than 3 year old and excavated from a depth of more than 2 m.

Abstract

Salah satu bentuk proses pengolahan air limbah secara fisik-kimia adalah adsorpsi. Pada pada proses adsorpsi digunakan adsorben untuk menyerap adsorbat. Sekam padi sebagai hasil sampingan pengolahan padi belum termanfaatkan dengan baik. Sekam padi dengan kandungan karbon dan SiO2 yang tinggi merupakan bahan yang baik untuk menghasilkan arang, Pemanfaatan sekam padi sebagai adsorben dengan menggunakan NaOH sebagai bahan aktifator untuk meningkatkan kapasitas adsorpsi dari arang yang dihasilkan. Untuk mengetahui kemampuan dari sekam padi dilakukan uji secara batch dengan variasi konsentrasi adsorben dan kecepatan agitasi dalam menurunkan warna limbah pencelupan tekstil. Hasil penelitian menunjukkan bahwa efisiensi penurunan warna tertinggi dengan adsorben sekam padi pada konsentrasi 100 mg/l sebesar 23 %.

Abstract

Limbah cair pabrik sarung tenun mengandung zat warna dengan kandungan COD, TSS yang tinggi dan logam berat Chrom (Cr) yang langsung dibuang ke sungai akan menimbulkan pencemaran. Dengan adanya uji toksisitas dapat diketahui nilai toksisitas limbah cair tersebut melalui prosentase kematian ikan Mujair (Tilapia mossambicus) sebagai salah satu biota uji. Metode penelitiannya adalah dengan prinsip acute toxicity test yang didahului dengan range finding test sehingga dapat ditemukan letal concentration-50 populasi biota uji, dimana nilai ini merupakan konsentrasi limbah yang bersifat toksik. Dilakukan pula uji untuk mengetahui kandungan Cr yang terdapat dalam tubuh biota uji dengan metode Ashing Furnice dan kerusakan pada insang dengan metode hispatologi insang. Berdasarkan penelitian yang dilakukan, LC-50, 96 jam pada ikan Mujair adalah 0,945%±0,045% dengan kandungan rata-rata COD 23,86 mg/l, TSS 33,28 mg/l, logam berat Cr total 0,06 mg/l dan zat warna 19,74 mg/l. Zat warna pada ikan Mujair tersebut mengandung senyawa azo = 1,55 mg/l, senyawa quinon = 1,44 mg/l dan senyawa naftol = 3,36 mg/l. Adanya kematian biota uji disebabkan adanya zat warna yang mengandung senyawa azo yang bersifat toksik. Adanya limbah pabrik sarung tersebut juga mengakibatkan perubahan histopatologi insang berupa hyperplasia lamella.

Abstract

The decrease in nitrogen concentration during the nitrification process of wastewater from the intensive shrimp ponds was observed by using the Horizontal Roughing Biofilter. The Horizontal Roughing Biofilter was run continuously with the low loadings and detention time variation of 1.0 , 1.5, 2.0 and 2.5 days. The waste water was taken from the effluent of shrimp ponds in Sidoarjo. The experiment showed that the average removal of nitrogen concentration was greater than 90%. The nitrification process followed the zero order reaction, and the reaction rate were influenced by the initial concentration of nitrogen and the detention time.
