Abstract

Plastic is an essential material in our daily lives. This study identifies that among various types of waste, multilayer plastic and styrofoam are one of the most difficult to manage optimally. One alternative to reduce this problem is to use waste as a mixture material for paving blocks. The composition of multilayer plastic and styrofoam used in this study were 65%:35%, 55%:45%, 45%:55%, and 35%:65%.This research only produced paving block samples that passed the visual test, size test, and average water absorption test. However, none of the samples passed the compressive strength, abrasion resistance, and sodium sulfate resistance tests according to the SNI 03-0691-1996 standards. Meanwhile, the water absorption test results for the 65%:35% and 55%:45% multilayer plastic-styrofoam samples met the quality standard C (for pedestrian use), while the 45%:55% and 35%:65% samples met the quality standard B (for parking equipment use).

Abstract

Separation technology using membranes utilizes renewable materials using natural polymers such as cellulose. Cellulose in particular has great potential as an alternative material for membrane materials or its derivatives such as cellulose acetate. Mother-in-law's tongue (Sansevieria trifasciata) contains 50-60% cellulose. This research aims to be able to maximize cellulose fiber through the synthesis process. Cellulose acetate which is the main material for making membranes will be optimized into cellulose acetate membranes with variations in the addition of PEG composition. After the process is complete, the sample is filtered and then washed until the pH is neutral and dried at 45oC until cellulose acetate is produced in the form of dry powder. After that, tests were carried out using the Fourier Transform Infra-Red (FTIR) instrumentation to determine the functional groups formed in cellulose acetate from cellulose fibers of mother-in-law's tongue. Preparation of SA membrane using phase inversion technique with precipitation technique with solvent evaporation. Prepare a vial to add 4 grams of dissolved 10 mL of acetone, stir and add PEG 600 with variation 2; 4 and 6 mL until well mixed. Prepare a glass plate measuring 10×10 cm which has been taped on all sides and covered with clear plastic, after which the polymer solution is poured and leveled and then left to stand until the SA membrane is dry. The results of the SA membrane thickness test showed the highest value on the 6 mL SA/PEG membrane with a value of 2.225 mm. Analysis of the results of membrane morphology using Scanning Electron Microscope (SEM) instrumentation shows that on the surface of the 2 mL SA/PEG membrane with 1000x magnification no pores are visible, the 4 mL SA/PEG membrane begins to show pores, while the SA/PEG membrane 6 mL, it can be seen that the more number of pores that are formed

Abstract

Household liquid waste, which is the residue from the activities of soapy water or bathing water, detergent water from washing clothes, faeces, washing water from cooking utensils containing oil in the settlement. This liquid waste problem needs to get serious attention, because it has complex characteristics and can disturb the health of the environment. One of the efforts to manage the environment is the processing of household wastewater through a series of physical and biological treatments, namely the aerobic biofilter process and using plant bioindicators, namely apu wood (Pistia stratiotes) which is able to absorb various heavy metals such as Fe, Zn, Cu, Cr, and Cd. Domestic wastewater used in this study was greywater, it was from kitchen activities. The purpose of this study was to determine the efficiency of reducing BOD, TSS, and fat oil in residual waste resulting from household activities by processing aerobic biofilter using bioball media and apu wood plants. The process of this research included the process of bacterial culture (seeding) for ± 2 (two) weeks and then proceeded by replacing new waste in the reactor for 5 (five) days at the biofilter reactor in which there was a bioball media and apu wood plants with downward and upward flow using a reactor made of glass with certain dimensions with a discharge of 0.35 ml/sec. The process results in a reduction efficiency of BOD of 70.51% from an initial BOD concentration of 300 mg/L to 88.49 mg/L. The efficiency of reducing TSS was 74.97% from the initial concentration of TSS 321 mg/L to 80.33 mg/L. In addition, the efficiency of reducing fat oil was 73.20% from the initial concentration of fatty oil 300.36 mg/L to 80.51 mg/L, so it can be explained that processing with bioball and apu wood plants can reduce the parameters of BOD, TSS, and fat oil, but the value was still above the standard quality of Minister of Environment Regulation No. 68/Menlhk/Setjen/Kum.1/8/2016.

Abstract

ABSTRAK Limbah cair laundry menjadi salah satu masalah pencemaran lingkungan karena mengandung deterjen, fosfat, surfaktan, dan bahan kimia lain yang berpotensi menurunkan kualitas perairan. Aktivitas ini dilakukan setiap hari sehingga membutuhkan pengolahan secara tepat agar dapat mengurangi beban pencemar di badan air. Salah satu pengolahan limbah cair laundry adalah dengan metode koagulasi-flokulasi menggunakan koagulan aluminium sulfat dan flokulan poliakrilamida. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi flokulan poliakrilamida dan menentukan dosis optimum flokulan terhadap persentase penyisihan kontaminan pada limbah cair laundry. Proses koagulasi-flokulasi limbah cair laundry dilakukan menggunakan metode jar test pada 1000 mL air limbah dengan pengadukan cepat 120 rpm selama 10 menit dan pengadukan lambat 30 rpm selama 20 menit. Dosis koagulan aluminium sulfat yang digunakan sebesar 4 g/L dan variasi dosis flokulan poliakrilamida yang digunakan 0.1, 0.2, 0.3, 0.4, 0.5, dan 0.6 g/L. Penambahan flokulan poliakrilamida tidak berpengaruh pada perubahan pH karena penurunan pH lebih dipengaruhi oleh penambahan koagulan aluminium sulfat. Persentase penyisihan tertinggi pada parameter TSS, COD, fosfat, dan MBAS diperoleh dengan dosis optimum flokulan sebesar 0.6 g/Ldengan masing-masing persentase penyisihan sebesar 96.52%, 45.65%, -37.23%, dan 88.36%. Kata kunci: Aluminium sulfat, flokulan, limbah cair laundry, poliakrilamida ABSTRACT Laundry wastewater is one of the environmental pollution problems because it contains detergents, phosphates, surfactants, and other chemicals that have the potential to reduce water quality. This activity is carried out every day so it requires proper processing to reduce the pollutant load in water bodies. One of the laundry wastewater treatment methods is the coagulation-flocculation method using aluminum sulfate coagulant and polyacrylamide flocculant. The purpose of this study was to determine the effect of variations in polyacrylamide flocculants and determine the optimum flocculant dosage on the percentage of contaminant removal in laundry wastewater. The coagulation-flocculation process of laundry wastewater was carried out using the jar test method on 1000 mL of wastewater with fast stirring at 120 rpm for 10 minutes and slow stirring at 30 rpm for 20 minutes. The aluminum sulfate coagulant dosage used was 4 g/L and the polyacrylamide flocculant dosage variations used were 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 g/L. The addition of polyacrylamide flocculant did not affect the pH change because the decrease in pH was more influenced by the addition of aluminum sulfate coagulant. The highest removal percentages for TSS, COD, phosphate, and MBAS parameters were obtained with an optimum flocculant dose of 0.6 g/L with removal percentages of 96.52%, 45.65%, -37.23%, and 88.36%. Keywords: Aluminum sulfate, flocculant, laundry waste, polyacrylamide
