Abstract

Nyamuk Island is located in the west part of the Karimunjawa islands where most of the local people are fishers who depend on fisheries as their main livelihood. Due to limited knowledge and facilities, many fisheries commodities are not utilized optimally. One of the basic needs of the local community is salt. Salt is an essential food ingredient in life. Community service activities through a creative business development program on salt production are offered as a solution to overcome the problem of the lack of salt quality.  Ideally, salt would be produced using Thread Filter Technology (TUF) with the addition of halophilic bacteria to speed the crystallization process. The quality of seawater influences the success of making salt using halophilic bacteria. Old seawater (with a salt content of at least 20° Be) is an ideal material for manufacturing salt using halophilic bacteria. One method for obtaining old water is salt production through the Thread Filter Technology (TUF) method. The project results are the salt demplots that produce high-quality salt and the availability of alternative livelihoods for the locals in Nyamuk Village. In the long term, alternative livelihoods such as salt making and fisheries product diversification will reduce pressure on the environment and prevent fishing from being carried out extensively. The availability of good quality salt for fish processing can extend fish marketing distribution chain quality and create new job opportunities for homemakers/widows so that they are provided an opportunity to have an income. The project results concluded that the Community Leading Commodity Strengthening activity carried out in the Nyamuk Village was beneficial for the community's welfare and the environment. --- Pulau Nyamuk adalah salah satu pulau di kepulauan Karimunjawa dengan sebagian besar masyarakat menjadi nelayan dan memanfaatkan laut sebagai mata pencaharian utama. Namun karena keterbatasan pengetahuan dan fasilitas banyak hasil tangkap tidak dimanfaatkan secara optimal. Salah satu kebutuhan pokok makanan masyarakat setempat adalah garam. Garam merupakan bahan pokok makanan penting dalam kehidupan, untuk itu perlu upaya pemberdayaan masyarakat tentang pembuatan garam. Kegiatan pengabdian masyarakat melalui program pengembangan usaha kreatif berbasis pembuatan garam ditawarkan sebagai solusi untuk mengatasi permasalahan ketiadaan garam berkualitas di Desa Nyamuk. Pembuatan  garam idealnya dilakukan dengan menggunakan penambahan bakteri halofilik yang bertujuan mempercepat proses kristalisasi garam. Keberhasilan pembuatan garam menggunakan bakteri halofilik dipengaruhi oleh kualitas air laut. Air laut tua (yang memiliki kadar garam minimal sama dengan 20° Be) merupakan bahan yang ideal untuk pembuatan garam dengan memanfaatkan bakteri halofilik. Salah satu metode untuk memperoleh air tua dalam pembuatan garam adalah melalui metode Teknologi Ulir Filter (TUF).  Hasil pengabdian ini merupakan alternatif tersedianya mata pencaharian bagi penduduk Desa Nyamuk. Hal tersebut merupakan upaya untuk mengurangi tekanan terhadap lingkungan jika terus-menerus dilakukan penangkapan ikan tanpa jeda buka tutup aktivitas penangkapan. Tersedianya garam berkualitas untuk pengolahan ikan diharapkan dapat memperpanjang kualitas ikan maupun rantai distribusi pemasaran ikan. Disamping itu juga tersedianya lapangan kerja baru bagi para ibu rumah tangga/janda sehingga memiliki peluang untuk memiliki penghasilan. Hasil pengabdian dapat disimpulkan bahwa kegiatan Penguatan Komoditi Unggulan Masyarakat (PKUM) yang dilaksanakan di Desa Nyamuk bermanfaatkan untuk kesejahteraan masyarakat dan lingkungan.

Abstract

Sekam padi yang merupakan limbah pertanian dapat menyebabkan pencemaran lingkungan apabila tidak ditangani dengan baik. Sekam padi mempunyai kandungan silika yang tinggi, sehingga berpotensi dimanfaatkan untuk berbagai aplikasi, salah satunya sebagai bahan pengisi barang jadi karet. Silika dari sekam padi dapat diperoleh dengan cara membakar sekam padi menjadi abu putih yang kaya kandungan silika dalam wujud amorf. Proses pembakaran dengan biaya murah, hemat energi dan dengan waktu cepat merupakan keuntungan dalam memproduksi silika amorf dari sekam padi. Fluidized Bed Combustor (FBC) merupakan alat yang bekerja dengan prinsip dasar hidrodinamika fluida yang mampu membakar sekam padi pada suhu pembakaran 600 0C untuk menghasilkan abu berwarna putih dengan kandungan silika amorf  mencapai 93% dengan cemaran karbon hanya sekitar 2,1%. Abu berwarna putih hasil pembakaran FBC dimurnikan dari ion-ion logam dengan proses pengkelatan dengan asam sitrat 5%, kemudian diekstraksi dengan larutan NaOH 1,5 N pada suhu 100 0C dan diendapkan dengan menggunakan larutan HCl 1 N pada suhu kamar. Silika amorf hasil dari proses pengendapan kemudian dikeringkan pada suhu 80 0C dan dicuci dengan air suling untuk memastikan ion-ion logam yang tidak diinginkan hilang.

Abstract

Pemanfaatan gadung (Dioscorea hispida Dennst) sebagai bahan baku dalam produksi makanan memiliki keterbatasan berkaitan dengan sifat fisikokimia tepungnya. Asetilasi merupakan salah satu metode modifikasi pati yang dapat digunakan untuk meningkatkan sifat fisikokimia pati, yakni swelling power, solubility, dan derajat substitusi. Tujuan dari penelitian ini adalah untuk mengetahu pengaruh rasio reaktan (asam asetat:tepung), waktu, dan pH reaksi terhadap nilai swelling power, solubility, dan derajat substitusi tepung gadung terasetilasi,serta mengetahui apakah nilai derajat substitusi berkorelasi dengan nilai swelling power dan solubility atau tidak. Asetilasi dilakukan dengan mendispersikan 20 gram tepung gadung ke dalam 100 mL akuades. Kemudian pH diatur hingga nilai tertentu (8, 9, dan 10) dengan penambahan NaOH 1 M. Slurry diaduk selama 30 menit. Setelah itu, asam asetat dengan rasio tertentu 1:3, 1:4, dan 1:5 (b/b) ditambahkan secara perlahan ke dalam campuran reaksi. pH campuran dijaga ke kondisi awal dengan penambahan NaOH 1 M. Reaksi dibiarkan berlangsung sesuai dengan waktu yang diinginkan (10, 20, 30, 40, 50, dan 60 menit). Reaksi dihentikan dengan penambahan HCl 1 M sampai pH 5,5. Tepung terasetilasi kemudian disaring dan dicuci dengan air suling sebanyak 3 kali dengan rasio berat tepung : air pencuci sebesar 1:3 (b/v). Tepung dikeringkan pada suhu 50oC dan digiling halus hingga 80 mesh. Kemudian dilakukan analisis terhadap nilai swelling power, solubility, dan derajat substitusi pada tepung gadung terasetilasi.

Abstract

The presence of glucomannan in Konjac (Amorphophallus oncophyllus) tuber flour has promoted its various applications, especially in the food, drink, drug delivery and cosmetics. Starch is the main impurity of Konjac tuber flour. Although the common wet refining method may result in a high purity Konjac tuber flour, it is very tedious, time consuming and costly. This research aimed to study the kinetics of starch degradation in the extrusion cooking process of dry refining method to produce high quality Konjac tuber flour. In this research, Konjac tuber flour with 20% (w/w) moisture was extruded in a single screw extruder by varying screw speeds (50, 75, 100, 125, 150 and 175 rpm) and barrel temperatures (353, 373, 393, 413 and 433 K). The results showed that the starch extrusion cooking obeys the first reaction order. The reaction rate constant could be satisfactorily fitted by Arrhenius correlation with total activation energy of 6191 J.mol−1 and pre-exponential factor of 2.8728×10−1 s−1. Accordingly, thermal degradation was found to be the primary cause of starch degradation, which shared more than 99% of the energy used for starch degradation. Based on mass Biot number and Thiele modulus evaluations, chemical reaction was the controlling mechanism of the process. The results of this research offer potential application in Konjac tuber flour refining process to obtain high quality flour product. Copyright © 2020 by Authors, Published by BCREC Group.

Abstract

Starch is a potential substrate for this purpose, but the extra cost is needed to hydrolyze it into reducing sugar. As an alternative to the expensive and energy demanding conventional hydrolysis process, the low-temperature hydrolysis is being studied. Granular Starch Hydrolysing Enzyme (GSHE) was used in the process to degrade starch into reducing sugar at 30°C and pH 4. The substrates included bitter cassava flour, sweet cassava starch, and gadung flour. Starch concentrations studied were 50, 100, 150, 200, 250, 300, 350, and 400 g/L, respectively, while concentration of enzyme was 1.5 % (w/w). The optimum condition of the process was hydrolysis using 200 g/L of substrate concentration and enzyme  concentration of 1.5% for 12 h. It was found that the reducing sugar was  49.3  g/L and the productivity of reducing sugar (Qrs) was 4.11 (gL-1 h-1).   Lineweaver-Burk plot of Michaelis-Menten equation was used to study the inhibition kinetics. The Michaelis-Menten constants (Km)  for these three substrates were determined as 141.64 g/L, 137,64 g/L and 140.84 g/L for bitter cassava flour, sweet cassava starch, and gadung flour, respectively. The value of  Vm/Km, which denotes the affinity of the enzyme to the substrate, were determined and compared, and the result showed that the affinity (Vm) to the enzyme to this substrate followed  the order of sweet cassava starch˃ bitter cassava flour˃ gadung flour, and all are non-competitive inhibitor, while the  Ki value was 0.022 h -1.

Abstract

Acetylation is one of the common methods of modifying starch properties by introducing acetil (CH3CO) groups to starch molecules at low temperatures. While most acetylation is conducted using starch as anhidroglucose source and acetic anhydride or vinyl acetate as nucleophilic agents, this work employ reactants, namely flour and glacial acetic acid. The purpose of this work are to study the effect of pH reaction and GAA/GF mass ratio on the rate of acetylation reaction and to determine its rate constants. The acetylation of gadung flour with glacial acetic acid in the presence of sodium hydroxide as a homogenous catalyst was studied at ambient temperature with pH ranging from 8-10 and different mass ratio of acetic acid : gadung flour (1:3; 1:4; and 1:5). It was found that increasing pH, lead to increase the degree of substitution, while increasing GAA/GF mass ratio caused such decreases in the degree of substitution, due to the hydrolysis of the acetylated starch. The desired starch acetylation reaction is accompanied by undesirable hydrolysis reaction of the acetylated starch after 40-50 minutes reaction time. Investigation of kinetics of the reaction observed that the value of mass transfer rate constant (Kcs) is smaller than the surface reaction rate constant (k). Thus, it can be concluded that rate controlling step is mass transfer. © 2015 by Authors, Published by BCREC Group.

Abstract

Membrane technology has gained attention in wastewater treatment due to its great potential for producing high-grade water products for reuse. The membrane also effectively removes persistent pollutants in water effluent. However, their application is constrained by low productivity due to fouling formation. Incorporating functionalized nanoparticles into polymeric membranes has attracted much attention due to the improved membrane performance and additional features. Metal-organic frameworks (MOFs) incorporated into polymeric membranes have been widely applied in reverse osmosis (RO), forward osmosis (FO), nanofiltration (NF), and microfiltration (MF) for water and wastewater treatment. This short review presented recent findings, fabrication methods, and a systematic understanding of transport mechanisms under various operating conditions. This study also focused on several important parameters, such as improving physicochemical properties, membrane features, and performance enhancement in wastewater treatment. The reported studies show that MOFs incorporated membranes have reached >95% organic pollutants and 100% suspended solids. The membrane durability was also enhanced up to 140%, and the flux recovery can be maintained at 98% after several cycles. Even some MOFs, such as ZIF-8 and UiO-66, exhibited excellent performance in harsh conditions (pH < 4). The prospects and challenges of MOFs-incorporated membranes in industrial applications were also provided in this study.

Abstract

The daily abundant generation of fruit peel waste potentially triggers environmental problems if no appropriate management is performed. Besides, fruit peel waste can be a valuable source for functional enzyme production. This study aims to investigate the use of molasses and palm sugar as sugar source during anaerobic fermentation of banana and papaya peel waste to produce functional enzymes. The fermentation was subjected to biomass at various banana peels to papaya peels mass ratio for 3 months. The feed consisted of sugar:biomass:water, and their mass ratio was kept constant at 1:3:10. Both brown functional enzyme cocktails obtained from the fermentation using palm sugar and molasses as carbon source were acidic with pH of 3.7 and 4.4, respectively. The amylase, protease, and lipase activities of the functional enzyme cocktails was maximum when the biomass mixture contained four portions of banana peel and one portion of papaya peel. In addition, molasses was found to be the better sugar source than palm sugar for producing functional enzymes from aerobic fermentation peel fruits comprises banana and papaya peels. This study proved that fruit peel waste can be converted to valuable functional enzymes as one of the solutions of fruit peel waste management Keywords: anaerobic fermentation; carbon source; enzyme activity; functional enzyme; organic waste

Abstract

Alkaline Polymer Electrolyte Fuel Cells (APEFCs) have emerged as a promising candidate for clean energy production. Anion exchange membrane (AEM) is an essential element of alkaline polymer electrolyte fuel cells for its role in facilitating hydroxide ion conduction. The objective of this study is to investigate the effect of a glutaraldehyde-based crosslinker solution on the performance of anion exchange membranes (AEMs) fabricated using quaternary ammonium poly (vinyl alcohol) (QPVA) as the backbone polymer and polyquaternium-7 as the second polymer. The introduction of a glutaraldehyde-based crosslinking agent was purposed to enhance membrane stability and reduce excessive swelling. The study evaluates the impact of varying glutaraldehyde concentrations on membrane performance. FTIR analysis confirms the presence of key functional groups of QPVA, polyquaternium-7, and the crosslinking agent. SEM images reveal that the membranes demonstrate dense and homogeneous physical structure. The results show that water uptake, swelling degree, ion exchange capacity (IEC), and hydroxide conductivity are influenced by the concentration of the glutaraldehyde solution. The QP-GA-13 AEM exhibited the best overall performance, achieving the highest tensile strength of 31.1 MPa and the highest hydroxide ion conductivity of 4.15 mS cm⁻¹ at 70°C. In single-cell tests, this membrane delivered a maximum power density of 85 mW cm⁻² and a current density of 350 mA cm⁻² at 80°C under humidified oxygen conditions.
