Abstract

Pertumbuhan industri dan kebutuhan masyarakat akan memberikan dampak seperti munculnya patogen seperti bakteri Escherichia coli dalam air. Hal ini akan berkontribusi pada penurunan ketersediaan air bersih. Proses desinfeksi diterapkan untuk mengurangi dan membatasi jumlah bakteri Escherichia coli di dalam air. Cuka kayu yang mengandung fenol merupakan salah satu bahan alternatif yang dapat digunakan sebagai disinfektan. Penelitian ini mengkaji penggunaan cuka kayu dalam proses desinfeksi. Proses desinfeksi dievaluasi berdasarkan variasi konsentrasi cuka kayu dan waktu kontak selama proses desinfeksi terhadap analisis jumlah bakteri (MPN) dan analisis residu fenol. Cuka kayu dari limbah serbuk gergaji telah memenuhi kualitas dari segi parameter pH, warna dan transparansi yang mengacu pada The Japan Pyroligneous Liquor Association. Cuka kayu memiliki kandungan fenol sebesar 1.022,456 ppm. Peningkatan konsentrasi fenol dapat meningkatkan daya hambat pertumbuhan Escherichia coli hingga 99,816% sedangkan peningkatan waktu kontak memberikan hasil yang fluktuatif. Proses desinfeksi menggunakan cuka kayu menghasilkan konsentrasi Escherichia coli dan fenol yang berada di atas regulasi jika dibandingkan dengan gas klorin.

Abstract

The Musi River's water is typically used to meet everyday needs. However, because of the current high population and activities, industrial and domestic garbage are being dumped straight into the Musi River. The purpose of this research was to study the variables that affect the processing of the Musi Riiver Water Samples to get the quality standard requirements of the third-grade river water. Water is filtered using a slow sand filter with a 50–70 cm sand height fluctuation and four different UV irradiation times 15, 30, 45, and 60 minutes. The results of this investigation showed that 2% DO was obtained for the filtration of Musi River water using a slow sand filter with a height of 70 cm sand. BOD5 and COD degradation were determined to be 82% and 93%, respectively. Meanwhile, 29/100 ml of E. Coli was discovered for the UV radiation therapy after a 60-minute irradiation period.

Abstract

Methylene blue is disastrous for the environment due to their high toxicity. This needs to be mitigated to ensure that the effects can be reduced. Pineapple peel waste (Ananas comosus) can be valorized as cellulose adsorbent and cellulose/PVA adsorbent is a potential solution to minimize the impact of these contaminants. The objective of this research is to investigate the performance of the cellulose/PVA composite in the methylene blue adsorption process and to evaluate its performance with a cellulose adsorbent. The adsorption process results showed that the percentage of MB removal reached 94.03% on the cellulose/PVA adsorbent with 9% NaOH delignification for 90 minutes. After adding PVA, there was a significant increase in the removal of methylene blue in the adsorbent was recorded. The results indicate that cellulose and cellulose/PVA composites are more effective adsorbents than cellulose alone for removing methylene blue.

Abstract

Pencemaran air merupakan masalah lingkungan yang sangat penting. Salah satu pencemar air adalah limbah minyak dan lemak dari industri minyak kelapa yang cenderung merusak lingkungan dan menurunkan kualitas hidup masyarakat. Pengolahan air limbah seperti elektrokoagulasi digunakan agar air limbah sesuai dengan peraturan dan menciptakan kehidupan yang berkelanjutan. Elektrokoagulasi digunakan untuk mengolah minyak dan lemak karena memiliki waktu proses yang singkat, memiliki efisiensi yang tinggi dan mudah dioperasikan. Penelitian ini mengevaluasi proses remediasi minyak dan lemak dalam reaktor elektrokoagulasi batch dengan berbagai kerapatan arus dan laju aerasi. Elektroda Al dan waktu kontak 30 menit digunakan dalam reaktor elektrokoagulasi. Minyak dan lemak dapat dihilangkan hingga 99.92% pada kondisi kerapatan arus 8.76 mA/cm2 dan laju aerasi 4.5 L/menit. Proses aerasi yang diterapkan pada proses elektrokoagulasi dipastikan dapat meningkatkan kinerja proses sebesar 13.22% bila dibandingkan dengan tanpa proses aerasi. Proses aerasi dapat memicu peningkatan mekanisme elektrokoagulasi melalui adsorpsi dan penjebakan oleh elektrokoagulan. Proses elektrokoagulasi dengan aerasi mencapai hasil yang meyakinkan meskipun kinerja sistem masih belum sesuai dengan peraturan yang berlaku.

Abstract

Pisang kepok merupakan salah satu makanan yang populer di Indonesia. Pisang kepok memiliki kecenderungan untuk menghasilkan limbah padat yang berdampak negatif terhadap lingkungan. Pemanfaatkan kulit pisang kepok sangat penting untuk mengurangi dampak negatifnya dan memberikan nilai tambah untuk memastikan kehidupan yang berkelanjutan dan ekonomi sirkular. Salah satu cara pemanfaatannya adalah dengan mengembangkan koagulan pektin alami dari kulit pisang kepok. Koagulan alami memiliki keunggulan seperti dapat terurai secara hayati, tidak beracun, tidak korosif, menghasilkan lebih sedikit lumpur namun memiliki nilai gizi yang tinggi dan biaya pengolahan lumpur yang minimal jika dibandingkan dengan koagulan kimia. Pektin digunakan sebagai koagulan alami untuk mengontrol total padatan tersuspensi dan chemical oxygen demand dalam industri laundry skala kecil. Pektin diekstraksi menggunakan asam klorida dan dikarakterisasi. Karakterisasi pektin menggunakan Fourier-Transform Infrared Spectroscopy, kandungan pektin, berat ekuivalen, kandungan metoksi, kandungan asam galakturonat, kandungan air, dan derajat esterifikasi. Proses koagulasi dan flokulasi dilakukan dengan memvariasikan dosis koagulan-flokulan dan waktu pengendapan. Kulit pisang kepok telah berhasil dimanfaatkan untuk mendapatkan pektin sebagai koagulan alami. Pektin terbukti efektif dalam menurunkan chemical oxygen demand dan total suspended solid dalam air limbah industri laundry skala kecil. Meningkatkan dosis pektin dan waktu pengendapan meningkatkan efisiensi penyisihan parameter polutan.  Kepok banana is one of the popular foods in Indonesia. It has tendency to create solid waste that has a negative impact on the environment. It is crucial to utilize kepok banana peel to mitigate its negative impact and add value to a circular economy. One way of utilization is by developing a natural pectin coagulant from kepok banana peel. Natural coagulants have advantages such as being biodegradable, non-toxic, non-corrosive, producing less sludge but high nutritional value and minimal sludge treatment costs when compared to chemical coagulants. Pectin is used as a natural coagulant to control total suspended solids and chemical oxygen demand in the small-scale laundry industry. Pectin was extracted using hydrochloric acid. Characterization of pectin using Fourier-Transform Infrared Spectroscopy, pectin content, equivalent weight, methoxy content, galacturonic acid content, water content, and degree of esterification. The coagulation and flocculation process were performed by varying the coagulant-flocculant dosage and settling time. Banana kepok peel has been successfully utilized to achieve pectin as a natural coagulant. Pectin proved to be effective in lowering chemical oxygen demand and total suspended solid pollutant characteristics in small-scale laundry industry wastewater. Increasing pectin dosage and settling time enhanced the removal efficiency of pollutant parameters.

Abstract

Chitosan, an environmentally friendly adsorbent, is derived from the deacetylation of crab shell chitin. In this study, the chemical and physical properties of chitosan were enhanced through the direct compositing process of magnetic chitosan (Chi) with fly ash powder particles (FA). This research is of considerable importance in the development of environmentally friendly adsorbent materials for the treatment of wastewater contaminated with synthetic dyes, particularly azo dyes such as congo red. The utilization of crab shell waste as a source of chitosan, in conjunction with fly ash and Fe₃O₄ to form Chi-FA-Fe₃O₄ magnetic composites, has been demonstrated to exhibit considerable promise in enhancing adsorption efficiency. The magnetic composite of Chi-FA-Fe₃O₄ was characterized by XRD and SEM. The present study investigated the effect of adsorption process parameters on CR dye removal. The parameters that were investigated included contact time (30-150 minutes) and initial concentration of CR dye at an adsorbent dosage of 0.06 grams in 100 milliliters and a pH of 4. The maximum removal efficiency of the Chi-FA-Fe₃O₄ composite for CR dye was recorded as 99.82% at an initial concentration of 100 parts per million (ppm) CR dye for 150 minutes. Pursuant to the analysis of XRD, it has been confirmed that the compositing process was successfully executed, thereby yielding 2θ values indicative of Fe₃O₄ and FA. Additionally, an enhancement in the intensity of the Chi-FA-Fe₃O₄ composite was observed following the adsorption of CR dye. Concurrently, SEM analysis revealed that the Chi-FA-Fe₃O₄ composite and the Chi-FA-Fe₃O₄ composite exhibited an augmented intensity.

Abstract

Many areas in Indonesia still have water sources that are unsuitable for daily use. One such area is the vicinity of Sungai Geneng Mosque, Kembang Bahu District, Lamongan Regency. In this area, the water source contains high levels of lime and organic materials, making it unsuitable for consumption. To address this issue, the Corporate Social Responsibility (CSR) Team from Politeknik Perkapalan Negeri Surabaya (PPNS) implemented a water filtration application in the area. The filtration method used is the anaerobic filtration system. Based on the filtration results, high levels of lime were successfully reduced to meet health standards, making the water clean and safe for consumption. Additionally, the organic materials in the water were converted into biogas, which serves as an alternative energy source for cooking and environmentally friendly vehicles.

Abstract

Tingginya beban pencemaran logam berat Cu(II) di badan air dapat diatasi dengan proses adsorpsi menggunakan adsorben. Abu ampas tebu dapat menjadi alternatif bahan baku pembuatan adsorben karena memiliki kandungan silika yang melimpah. Kelemahan dari silika adalah memiliki sifat keasaman yang rendah serta memiliki oksigen sebagai atom donor yang bersifat lemah. Hal ini menyebabkan kemampuan adsorpsi silika menjadi kurang baik. Dalam rangka memperbaiki sifat tersebut maka, dilakukan modifikasi dengan menggunakan kitosan. Pada penelitian ini bertujuan untuk mensintesis serta mengkarakterisasi adsorben dari silika yang dimodifikasi dengan kitosan. Penelitian dilakukan untuk menganalisis dosis penambahan kitosan optimum dalam penurunan kandungan Cu(II) pada proses adsorpsi. Metode adsorpsi yang digunakan pada penelitian ini adalah sistem batch, yaitu dengan memasukkan setiap adsorben pada larutan Cu(II) 50 ppm selama 50 menit. Dosis penambahan kitosan yang ditambahkan sebanyak 0,5 gram; 1 gram; 1,5 gram; dan 2 gram. Hasil XRD menunjukkan adsorben yang disintesis bersifat amorf. Analisis FT-IR menunjukkan munculnya gugus fungsi –OH, Si-O-Si, Si-OH, Si-O-C, -NH, dan NH2. Uji BET menunjukkan bahwa adsorben memiliki luas area spesifik sebesar 2,33 m2/g. Morfologi dari silika berubah ketika dimodifikasi dengan kitosan dari yang sebelumnya adalah heterogen menjadi partikel-partikel besar yang teraglomerasi. Pada analisis EDX dapat diidentifikasi adanya unsur C, N, O, dan Si. Hasil penelitian menyatakan bahwa penambahan massa kitosan yang optimum adalah 2 gram dengan efisiensi removal logam berat Cu(II) sebesar 99,85%.ABSTRACTThe high concentration of Cu(II) in the water cause several diseases to the human being. It can be dealt with by the adsorption process using adsorbents. Bagasse ash can be an alternative raw material for making adsorbent due to its abundant silica content. The weakness of silica has low acidity and oxygen as a weak atomic donor. It causes a bad adsorption ability on the adsorbent. In order to improve those characteristics, modifications are needed, for example, by using chitosan. This research aims to synthesize and characterize the adsorbent from silica-chitosan. The research was conducted to analyze the optimum dosage of chitosan and reduce Cu(II) content in the adsorption process. The adsorption method used is a batch system by entering each adsorbent in a 50 ppm of Cu(II) solution for 50 minutes. The dosage of chitosan addition are 0,5 gram; 1 gram; 1,5 gram;and 2 gram. XRD results show that the synthesized adsorbent is amorphous. The presence of -OH, Si-O-Si, Si-OH, Si-O-C, -NH, and –NH2 groups are shown in FT-IR analysis. BET analysis shows that the adsorbent has an area of 2,33 m2/g. The morphology of silica changes when modified with chitosan from a heterogeneous form into agglomerated large particles. EDX analysis can identify the elements of C, N, O, and Si. The results of the research stated that the addition of the chitosan mass optimum is 2 grams with the ability to remove heavy metals Cu(II) of 99,85%

Abstract

The population growth rate has been demonstrated to have a direct impact on the increase in pollutant concentrations released into water bodies. One of the pollutants that has been identified in water bodies is congo red. This necessitates the implementation of effective management strategies to mitigate the adverse effects of pollutants. A methodology that has been demonstrated to be effective in mitigating the impact of congo red is the coagulation-flocculation process. The objective of this study is to employ biocoagulants and magnetic biocoagulants derived from moringa oleifera as mass separation agents to mitigate the adverse effects of congo red. The effectiveness of the mass separation agents was evaluated with varying initial concentrations of congo red. The augmentation of the initial congo red concentration yielded consistent results for both biocoagulants and magnetic biocoagulants. The highest results were obtained at an initial congo red concentration of 100 ppm, with a value of 97.34% for the magnetic coagulant. The coagulation-flocculation process can occur through several mechanisms, including charge neutralization, floc formation, and sedimentation.

Abstract

The mangrove crab (Scylla serrata) represents a notable component of the Indonesian marine biota. The utilization of mangrove crabs as a food source results in the deposition of shell waste. The shells of these crustaceans contain chitin, which can be synthesised into chitosan. One of the advantages of chitosan is that it can be utilized as a coagulant to reduce congo red dye. This study aimed to evaluate the potential of mangrove crab shell-based chitosan and its performance in the coagulation and flocculation process using the jar test method. The chitosan derived from mud crab shells exhibited a degree of deacetylation (DD) value of 74%. The operating parameters for the coagulation and flocculation process were a coagulant dosage of 25-150 mg/L and a congo red concentration of 100-250 mg/L. The results of the study demonstrate that an increase in coagulant dose results in enhanced treatment performance, reaching a point of saturation where performance declines or stabilizes. Similarly, elevated initial Congo red concentrations also influence the effectiveness of higher coagulation. The removal of congo red dye with the effect of coagulant dose and initial concentration of congo red resulted in a percent removal of up to 99.9% at a coagulant concentration of 150 mg/L and a congo red concentration of 250 mg/L
