Abstract

Kayu jelutung (<i>Dyera costulata</i>) merupakan salah satu jenis tanaman endemik di Kalimantan yang mulai langka. Tujuan penelitian ini adalah untuk menganalisis karakteristik pertumbuhan kayu jelutung yang dibudidayakan oleh masyarakat di Kalimantan Tengah di lahan gambut. Pengolahan lahan dengan tanpa bakar menjadikan hutan tanaman rakyat (HTR) ini ramah lingkungan. Sebanyak 38 pohon jelutung dari 1 blok HTR diukur diameter dan tinggi pohonnya, selanjutnya dikelompokkan dalam kategori pertumbuhan cepat, sedang, dan lambat. Dari masing-masing kelompok diambil 1 pohon yang memenuhi persyaratan. Sampel setebal 2 cm diambil dari ketinggian 1,3 m dari permukaan tanah dan setiap 2 meter ke arah ujung pohon untuk pengukuran kadar air (KA), berat jenis (BJ), anatomi kayu, nilai turunan serat, dan kandungan kimia kayu. Hasil pengujian menunjukkan bahwa kayu jelutung memiliki BJ rendah dan serat pendek sehingga termasuk kelas 2 untuk pembuatan pulp dan kertas. Kandungan kimia kayu jelutung menunjukkan kandungan ektraktif larut alkohol benzena yang cukup rendah dan bisa digunakan sebagai bahan baku pulp dan kertas. Selain itu, kayu jelutung juga sesuai untuk digunakan sebagai bahan kayu lapis. Characteristics of Jelutong Wood ((<i>Dyera costulata</i>) from Community Forest in Central KalimantanAbstractJelutong wood (<i>Dyera costulata</i>) is one of the endemic tree species in Kalimantan which is starting to become scarce. This research aims to analyze the growth characteristics of jelutong wood planted by the community in peatland in Central Kalimantan. Land processing without burning makes this community plantation forest environmentally friendly. Thirty-eight trees of jelutong from one block were measured diameter and three height, end then categorized to fast, medium, and slow-growing. One tree from each category was harvested. Two centimeters of the disk were collected from each harvested trees from a 1.3 meter height and continued every 2 meters to the peak of trees to measure water content, specific gravity, anatomical properties, derived wood, and chemical content of jelutong wood. From the analyses, jelutong has low specific gravity and short fibers, categorized into class two for pulp and paper raw materials. Extractive content in alcohol benzene from jelutong wood was low that preferable for pulp and paper. On the other hand, jelutong wood is suitable for plywood raw materials.

Abstract

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

Biodiesel is a fuel derived from renewable sources, wich can be used efficiently in petrodiesel engines. This study aims to produce biodiesel from tamanu oil enzymatically using the lipase enzyme. This enzimatic method has a high value product made during the production of biodiesel. Biodiesel production through the transesterification process with methanol reactant and alkaline catalysts has many weaknesses, namely the presence of a saponification reaction and it is difficult to separate because the catalyst is homogeneus. The result of this study indicate that tamanu oil has been seccessfully converted into biodiesel with an optimum oil : methanol molar ratio of 1:5 and a yield precentage of 87,67% with a methyl ester content of 97,37%

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.

Abstract

Effectiveness of Liquid Smoke Purification of Sawdust by using Distillation Method, Zeolite and Active Carbon AdsorptionAbstractLiquid smoke is a product resulting from the pyrolysis of biomass under conditions of minimal oxygen. The compounds of liquid smoke is influenced by the type of biomass, water content, process temperature and the length of pyrolysis time. In general, liquid smoke is dark brown in color with an acidic and has a unique aroma and taste, depending on the type of biomass. Liquid smoke chemical compounds characterize organoleptic, antimicrobial and antioxidant, in addition to functional compounds sometimes also produce harmful compounds such as a group of polycyclic aromatic hydrocarbon compounds, and 2-propanone, 2-butanone, cyclopentanone which are toxic or carcinogenic. Crude liquid smoke may contain several mixtures of hazardous compounds depending on the process conditions, so it cannot be directly applied to food products. To get quality liquid smoke, it is necessary to carry out a purification process to reduce or eliminate harmful compounds. Methods that have been widely applied include distillation and adsorption processes. This study aims to measure the effectiveness of zeolite and activated carbon in the purification of liquid smoke with mixed sawdust biomass as raw material. Liquid smoke is purified by distillation, and adsorption with several adsorbents. The results obtained indicate that the liquid smoke still contains 2-propanone ,2-butanone and cyclopentanone. Zeolite ZG2 showed the best effectiveness in removing the three harmful compounds, while ZK1and Cca still left 2-propanone in liquid smoke. Thus zeolite ZG2 is effective as an absorbent in the purification of liquid smokeKeywords: Liquid Smoke, Adsorption, Biomass, Sawdust Abstrak Asap cair adalah produk yang dihasilkan dari pirolisis biomassa pada kondisi minim oksigen. Komposisi senyawa asap cair dipengaruhi oleh jenis biomassa, kadar air, dan suhu proses serta lama waktu pirolisis. Pada umumnya asap cair berwarna cokelat tua dengan pH asam dan memiliki aroma serta rasa yang unik, tergantung dari jenis biomassanya. Senyawa kimia asap cair mencirikan sifat organoleptik, antimikroba dan antioksidan, selain senyawa fungsional terkadang juga menghasilkan senyawa berbahaya seperti kelompok senyawa Polycyclic aromatic hydrocarbon, dan 2-propanone, 2-butanone, cyclopentanone yang bersifat toksik atau karsinogenik. Asap cair crude dimungkinkan terdapat beberapa campuran senyawa berbahaya tergantung dari kondisi prosesnya, sehingga tidak dapat secara langsung diaplikasikan untuk produk pangan. Untuk mendapatkan asap cair berkualita perlu dilakukan proses pemurnian untuk mengurangi atau menghilangkan senyawa berbahayanya. Metode yang telah banyak diaplikasikan antara lain dengan proses distilasi dan adsorpsi. Penelitian ini bertujuan mengukur efektifitas zeolite dan karbon aktif dalam pemurnian asap cair dengan bahan baku biomasa serbuk gergaji campuran. Asap cair di lakukan pemurnian dengan destilasi, dan adsorpsi dengan beberapa adsorben. Hasil yang diperoleh menunjukkan bahwa asap cair masih mengandung 2-propanone ,2-butanone dan cyclopentanone. ZG2 menunjukkan efektifitas yang paling baik mampu menghilangkan ketiga senyawa berbahaya tersebut sedangkan ZK1 dan Cca masih menyisakan 2-propanone dalam asap cair. Dengan demikian zeolite ZG2 efektif sebagai absorben dalam pemurnian asap cair Kata kunci : Asap  Cair, Adsorpsi, biomassa, serbuk gergaji kayu
