Abstract

Identification of Volatile Fatty Acids from Palm Oil Mill Effluent for Polyhydroxyalkanoate Production by Ralstonia eutropha JMP 134 Abstract Polyhydroxyalkanoate (PHA) is a bioplastic which is derived from bacterial fermentation. In this study, PHA is produced by utilizing Ralstonia eutropha JMP 134 and volatile fatty acids (VFA) from palm oil industrial wastewater as a precursor. The aim of this research is to study the effect of carbon source, addition time, and VFA concentration on PHA production by fermentation using Ralstonia eutropha JMP 134 in batch. PHA and dry cell weight (DCW) concentrations obtained by adding VFA from palm oil industrial wastewater in batches at 20 and 40 hours were 0.014 g/L.hour, 2.76 g/L and 3.66 g/L, respectively. The results also showed that the time of adding VFA greatly affected cell growth, with the best addition time being after the 20th hour. Keywords: palm oil industrial wastewater, polyhydroxyalkanoate (PHA), batch, Ralstonia eutropha JMP 134, volatile fatty acids (VFA) Abstrak Polihidroksialkanoat (PHA) adalah bioplastik yang diproses melalui proses fermentasi dengan mikroba.

Abstract

Characterization of Distilled and Vacuum Distilled Liquid Smoke from Pine Litter WasteAbstractThe solid waste of pine litter in the form of leaves, strobilus, and pine sawdust in the gondorukem and turpentine factories is still minimally utilized and causes environmental problems. However, the presence of cellulose, hemicellulose, and lignin content makes pine litter potential to be used as liquid smoke through the pyrolysis process. Liquid smoke has many benefits, including as an antiseptic and food preservative, but the characteristics of liquid smoke from pine litter are not yet known, so it requires further study. This research aims to determine the characteristics of smoke from pine litter waste, especially the composition of its chemical components, so the possibility for wider utilization can be known. The manufacture of liquid smoke is carried out through pyrolysis on pine litter waste, then given vacuum distillation treatment as a purification attempt. Tests on both samples using yield parameters, pH, total acid value, color organoleptic properties, specific gravity, and analysis of chemical components using gas chromatography-mass spectrometry. The results showed that the yield of liquid smoke and charcoal from waste pine litter is low, but the yield of vacuum distilled liquid smoke is huge. The distilled liquid smoke had a darker color, lower pH, higher total acid, and higher specific gravity than vacuum distilled liquid smoke. In general, the chemical components identified in both groups are divided into carbonyl, aryl alkyl ether, alkane, organic acids, and phenolic compounds. The content of phenolic compounds and furfural as the dominant compounds opens opportunities for use as wood preservatives, food preservatives, topical analgesics, antiseptics, fungicides, and nematocides.Keywords: liquid smoke, pine litter waste, vacuum distillation, chemical compound, characterizationAbstrakLimbah padat serasah pinus berupa daun, strobilus, dan serbuk kayu pinus di pabrik gondorukem dan terpentin masih minim pemanfaatannya dan menimbulkan masalah lingkungan. Serasah pinus memiliki kandungan selulosa, hemiselulosa, dan lignin yang berpotensi untuk dimanfaatkan sebagai asap cair melalui proses pirolisis. Asap cair memiliki banyak manfaat, di antaranya sebagai bahan antiseptik dan pengawet makanan. Namun asap cair dari limbah serasah pinus masih belum diketahui karakteristiknya, sehingga membutuhkan pengkajian lebih lanjut. Penelitian ini dilakukan untuk mengetahui karakteristik asap cair dari limbah serasah pinus berdasarkan sifat fisik dan susunan komponen kimianya, sehingga dapat diketahui peluang pemanfaatannya secara lebih luas. Pembuatan asap cair dilakukan melalui proses pirolisis pada limbah serasah pinus, lalu diberikan variasi perlakuan distilasi vakum sebagai upaya purifikasi. Pengujian pada asap cair distilasi dan asap cair terdistilasi vakum menggunakan parameter rendemen, pH, nilai total asam, sifat organoleptik warna, bobot jenis, dan analisis komponen kimia menggunakan gas chromatography-mass spectrometry. Hasil penelitian menunjukkan bahwa asap cair dari limbah serasah pinus distilasi memiliki warna yang lebih gelap, pH yang lebih rendah, total asam yang lebih banyak, dan bobot jenis yang lebih tinggi daripada asap cair terdistilasi vakum. Secara umum, komponen kimia yang teridentifikasi pada keduanya terbagi dalam kelompok karbonil, alkana, aril alkil eter, senyawa asam, dan senyawa fenolik. Asap cair distilasi mengandung beberapa senyawa dari kelompok terpena dan terpenoid, sedangkan asap cair distilasi vakum mengandung senyawa dari kelompok alkaloid. Kandungan senyawa fenolik dan furfural sebagai senyawa dominan membuka peluang pemanfaatan sebagai pengawet kayu, pengawet makanan, analgesik topikal, antiseptik, fungisida, dan nematosida.Kata Kunci: asap cair, limbah serasah pinus, distilasi vakum, komponen kimia, karakterisasi

Abstract

Indonesia merupakan penghasil limbah plastik terbesar kedua setelah Cina, sehingga telah menjadi isu lingkungan. Salah satu kemasan plastik yang banyak digunakan adalah kemasan untuk pembibitan terbuat dari plastik atau dikenal sebagai polybag. Guna membantu mengurangi penggunaan polybag, telah dilakukan percobaan skala laboratorium pembuatan paper bag dari pulp tandan kosong sawit (TKS) sebagai pengganti polybag. Penelitian ini bertujuan untuk mendapatkan formula pembuatan paper bag yang dapat memenuhi persyaratan penggunaan akhirnya. Kegiatan dimulai dari penggilingan pulp TKS, dilanjutkan dengan pembuatan lembaran dengan variasi gramatur 90 g/m2 dan 125 g/m2 pada rentang pH 7-8. Dua jenis bahan kimia penguat basah yang digunakan yakni polietilen imin (PEI) dan poliamin epiklorohidrin (PAE), ditambahkan dengan variasi dosis 1,0 – 2,0 % terhadap berat kering serat. Karakteristik lembaran dievaluasi melalui uji ketahanan tarik, daya regang, daya serap energi (tensile energy absorption atau TEA), ketahanan retak, ketahanan sobek, persen rendemen kekuatan setelah mengalami pembasahan, dan porositas. Uji biodegradabilitas dilakukan untuk melihat tingkat afiliasi bahan kimia yang ditambahkan terhadap lingkungan dan rasio C/N (rasio karbon/nitrogen) untuk mengetahui kontribusinya terhadap proses pengomposan. Hasil percobaan menunjukkan bahwa lembaran memiliki rendemen ketahanan tarik di atas 10%. Gramatur berkorelasi positif terhadap sifat kekuatan, dan negatif terhadap porositas. PAE memberikan sifat kekuatan lebih tinggi dibanding PEI, namun PEI memberikan persen rendemen ketahanan tarik lebih tinggi dibanding PAE. Seluruh bahan kimia yang ditambahkan dapat didegradasi lebih dari 60% dalam kurun waktu 28 hari namun uji rasio C/N menunjukkan hasil yang belum memadai. Formula optimum diperoleh pada gramatur 125 g/m2 dengan penambahan PEI 2%. Paper Bag Based on Empty Fruit Bunches Pulp as an Alternative for Polybag Substitute in Pre-Nursery Palm Oil PlantationAbstract Indonesia is the second-largest plastic waste producer after China, so it has become an environmental issue. One of the plastic packagings which are large in consumption for nursery packaging is known as polybag. Therefore, to reduce the use of plastic bag, the laboratory scale experiment of paper bag made from oil palm empty fruit bunches (EFB) as polybag substitutes has been done. This study aims to obtain a formula for paper bags that can meet the end using requirements. Laboratory scale started from beating the EFB pulp, then continued with handsheet making at grammage variation of 90 g/m2 and 125 g/m2 with a pH range of 7-8. Two types of wet strength agents were used, namely polyethyleneimine (PEI) and polyamine epichlorohydrin (PAE) which were varied from 1.0 to 2.0% (%db of fiber). Sheet properties were evaluated through tensile and bursting strength, stretch, TEA tests, tearing resistance, % yield of strength after wetting, opacity, and porosity. A biodegradability test was conducted to determine the chemical’s affiliation level to the soil and the C/N ratio to know its contribution to the composting process. The results showed that the paper bag has a tensile strength yield above 10%. Grammage is directly proportional to strength properties and inversely to porosity. PAE gave higher strength than PEI but is lower in % yield of tensile strength. All added chemicals can be degraded by more than 60% within 28 days but the C/N ratio test showed inadequate results. The optimum formula was obtained at 125 g/m2 and PEI of 2.0%.

Abstract

Cellulose and chitin are two of the most abundant biopolymer on earth, have been attracted a lot of interest from many researchers, especially related to their nanoparticles form. Recently the method to extract them into nanoscale materials mostly by mineral or liquid acid hydrolysis, such as sulfuric and hydrochloric acid. Despite their high yield production, many disadvantages are produced by their use as a hydrolysis catalyst, such as low thermal stability and are difficult to be functionalized due to the presence of sulfate groups, tendency to be aggregated due to the bare surface charge density, the potential excessive degradation of cellulose; and large amounts of effluent will be produced due to the neutralization stage and corrosion hazards to the equipment and environment. To overcome the drawback of those acids, solid acid can be used to produce cellulose (CNC) and chitin nanocrystals (ChNC). Their ability to recrystallize and recycle makes them more environmentally friendly, furthermore, most of the acid can do esterification on the surface of cellulose and chitin. The purpose of this paper is to provide a critical review of recent progress related to solid acid hydrolysis since they have interesting characterization even some of their attribute is better than the conventional method.

The Effect of Gamma Iradiation Dosage Variation on The Separation of Coconut Coir Lignocellulose Biomass ComponentsAbstractIndonesia has the potential for lignocellulosic biomass in the form of coconut coir, which is very abundant. The components of coconut coir are lignocellulosic biomass, which consists of cellulose, hemicellulose, and lignin and can be separated from one another. This study was conducted to determine the effect of variations in the dose of gamma-ray irradiation on the structure of each component so that it was expected that the utilization of coconut coir lignocellulosic biomass could be more comprehensive. The separation was carried out using wet irradiation with a 5% H2O2 solution as the initiator, where 15 grams of coco coir sample was dissolved in 60 ml of 5% H2O2 solution. Gamma irradiation dose variations were 0 kGy, 50 kGy, 100 kGy, 150 kGy, and 200 kGy. Based on the research, the optimal dose to obtain glucose was obtained at an irradiated dose of 100 kGy with a glucose level of 5.09 mg. The optimal gamma irradiation dose for lignin separation is 50 kGy with a lignin separation percentage of 34.95%. Based on the FTIR analysis, it can be seen that as a result of the chemical bond resulting from the separation, there is a decrease in the effect of the gamma IR radiation. This study showed that the separation of lignocellulosic coconut coir biomass using gamma irradiation could produce higher levels of glucose and lignin separation and affect the chemical structure of cellulosic biomass

Abstract

Use of Modified Chitosan and Cationic Starch as Wet Strength Agents on Interleave PaperAbstractWet strength resins commonly used in the paper industry to date are formaldehyde-derived resins, epichlorohydrin polyamide resins, and epoxide resins. These conventional resins have weaknesses such as containing monomer groups that are toxic, difficult to degrade and harmful to health and the environment. Therefore, it is necessary to innovate to overcome these weaknesses, one of which is the development of biopolymer resins. One type of biopolymer is chitosan modified with maleic anhydride so that it has the characteristics of being non-toxic, biodegradable, anti-bacterial, and odorless. With the addition of cationic starch, modified chitosan will work more effectively to produce good strength properties on interleave paper. This laboratory scale study aims to determine the effect of the addition of modified chitosan and cationic starch on the wet and dry strength properties of paper. The test results showed that the addition of 0.7% modified chitosan and 1% cationic starch gave the highest strength properties. The addition of modified chitosan and cationic starch affects the physical properties of the paper such as wet and dry tensile strength index, tearing strength index, bursting strength index, water absorption, and surface pH.Keywords: maleic anhydride, cationic starch, wet strength, interleave paper, modified chitosanAbstrakResin-resin penguat basah yang umum digunakan di industri kertas hingga saat ini adalah resin turunan formaldehid, resin poliamida epiklorohidrin, dan resin epoksida. Resin-resin konvensional ini memiliki kelemahan diantaranya mengandung gugus monomer yang toksik, sulit terdegradasi, berbahaya bagi kesehatan dan lingkungan. Oleh karenanya perlu dilakukan inovasi untuk mengatasi kelemahan tersebut, salah satunya adalah pengembangan resin biopolimer. Salah satu jenis biopolimer adalah kitosan dimodifikasi dengan anhidrida maleat sehingga memiliki karakteristik tidak beracun, dapat terurai secara hayati, anti bakteri, dan tidak berbau. Dengan penambahan pati kationik, kitosan modifikasi akan bekerja lebih efektif untuk menghasilkan sifat kekuatan yang baik pada kertas interleave. Penelitian skala laboratorium ini bertujuan untuk mengetahui pengaruh penambahan kitosan yang dimodifikasi dan pati kationik terhadap sifat kekuatan basah dan kering kertas. Hasil pengujian menunjukkan bahwa penambahan 0,7% kitosan yang dimodifikasi dan pati kationik 1% memberikan sifat kekuatan paling tinggi. Penambahan kitosan modifikasi dan pati kationik berpengaruh pada sifat fisik kertas seperti indeks tarik basah dan kering, indeks sobek, indeks retak, daya serap air dan pH pada permukaan.Kata Kunci: anhidrida maleat, pati kationik, kekuatan basah, kertas interleave, kitosan modifikasi
