Abstract

Peat water in terms of quality cannot be used as a source of clean water or drinking water, so it needs to be processed. One alternative treatment that can be used is the adsorption process with a column system using a chitosan membrane (the content of amine groups contained in the chitosan membrane has a good ability to absorb metals). This study aims to remove Fe metal in peat water. Variations carried out were Fe concentrations of 2, 3 and 4 mg/L and flow rates of 2, 3, 4 and 5 mL/minute. The results obtained are the best Fe metal removal efficiency of 92.20% with a final concentration of 0.312 mg/L at an Fe concentration of 4 mg/L and a flow rate of 2 mL/minute. The results of the study have met the quality standards set by the Minister of Health of the Republic of Indonesia Number 32 of 2017 concerning Sanitary Hygiene

Abstract

Water pollution by heavy metals is a serious problem. One of the dangerous parameters that contaminate waters is heavy metals that come from metal industrial waste. Electroplating wastewater contains heavy metals that are harmful and toxic to the environment. Alternative treatment that can be used is the adsorption process with a column system using chitosan-clay beads. Chitosan has amine and hydroxyl groups which have ability to absorb heavy metals. The results of the characterization by FTIR (Fourier Transform Infrared) test on chitosan produced contained a chitosan functional group and obtained a DD value of 80.97%. This study aims to remove Cr (VI) in electroplating wastewater. The variations carried out were variations in the ratio of the composition of chitosan-clay beads (w/w) (1.5:1), (2:1), (2.5:1) and a flow rate 3 mL/minute; 3.5 mL/min; and 4.5 mL/min. The results of the water absorption test (DSA) obtained for each variation of chitosan-clay beads were 609.52%; 628.27%; 658.04%, and the results of the compressive strength test are 22.491; 10,653; 3,015 Kgf. The results obtained are the best Cr (VI) removal efficiency of 95.46% with concentration of Cr (VI) 1.1566 mg/L at the ratio of chitosan-clay beads composition (2,5:1) (w/w) and flow rate 3 mL/min.

Abstract

Ledakan dan kebekaran merupakan kegagalan proses yang tidak diinginkan apabila terjadi pada industri minyak. Kegagalan tersebut disinyalir dapat terjadi akibat kurangnya maintanance alat dan kelalaian kerja. Perlu adanya identifikasi serta pengecekkan pada setiap alur proses pengolahan minyak, guna membantu menentukan titik terbesar kemungkinan terjadinya kegagalan tersebut. Pada penelitian ini titik lokasi identifikasi berada pada area pengumpul minyak mentah di industri X (Gathering Station). Penelitian ini dilakukan karena terdapat area produksi minyak mentah (on shore) sehingga perlu dilakukannya proses identifikasi yang akurat. Metode identifikasi yang dipilih untuk diaplikasikan dalam menemukan kegagalan ini adalah metode Failure Mode and Effect Analysis (FMEA) dengan pengembangan konsep lean-waste serta dibantu dengan analisis penyebab kegagalan menggunakan Root Cause Analysis (RCA), serta pemberian data secara kuantitatif dengan menambahkan metoda diagram Pareto untuk memperoleh persentase kegagalan yang terjadi. Berdasarkan hasil identifikasi, diperoleh 2 jenis waste yaitu Defect dan Inappropriate processing. Defect waste terjadi pada penyambung pipa utama bocor dengan nilai Risk Priority Number (RPN) tertinggi yaitu 170,02 dan persentase Pareto adalah 17,9%, sedangkan Innapropriate processing waste terjadi pada arus listrik pendek di shipping tank dengan nilai RPN tertinggi 131,63 dan persentase Pareto sebesar 17,8%.

Abstract

Peat water is raw water which is used as a source of clean water by the people of Pekanbaru. However, after testing according to the Regulation of the Minister of Health of the Republic of Indonesia for clean water standards No. 416/MENKES/PER/IX/1990 the results of measuring the color and turbidity value of peat water are above the quality standards, namely 219 TCU and 15.1 NTU. This value is very far from the color and turbidity quality standards with respective concentrations of 15 TCU and 5 NTU. Therefore, in this research, an adsorption process was carried out using an adsorbent from Patin bone waste (Pangasius sp.) typical of Riau province by utilizing a physical activation process to open pores and help facilitate absorption. The variable used in this research were adsorbent mass and stirring speed. For adsorbent mass there was a variation of 0.1; 0.3; 0.5; and 0.7 grams while the stirring speed was 50, 100, and 150 rpm with a stirring time of 120 minutes and each sample had a particle size of 100 mesh. The results of this adsorption process obtain the best efficiency value at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm. The color reduction efficiency reached 96.35%, namely 8 TCU, while the turbidity reduction efficiency at Patin bone mass of 0.7 grams with a stirring speed of 100 rpm reached 92.72%, namely 1.1 NTU.

Abstract

Supercapacitors are increasingly developing energy storage devices because they have advantages over conventional batteries and capacitors, such as high power density and long cycle life. Electrolytes are solutions that contain ions and function as electrically conductive media. In chemistry, electrolytes usually consist of acid, base, or salt solutions. The electrolyte used in supercapacitors plays a crucial role in achieving the desired power and energy density. In general, electrolytes are divided into two types based on their phase form, namely liquid and solid or gel electrolytes. Liquid electrolytes can be acids, bases or salts. While gel electrolytes are electrolytes that are denser in nature so that they can reduce leakage.
