Abstract

The purpose of this work is to provide seminar needs (seminar kit) as compliments of seminar or symposium held by university including Universitas Sumatera Utara (USU). Method of this activity included launching of our main products, namely eco-print both on paper and on fabric. In this work, eco-print products on recycle papers was used as exclusive block-note covers while eco-print products on fabric were used as tote-bag materials. There were two advantages of using these products, firstly: they were made of natural ingredients without chemical synthetic materials; and secondly the products were designed specifically; one product was not similar with the others. This activity involved two partners, namely a recycle-paper producer and a tailor who make tote-bag. Result on progress of this activity was an order for seminar kit through exhibition. During the evaluation of this project it was found that Nauli Apik USU, as a seminar kit’s producer, still depends on workers whom working manually and having individual skill. In the future, management of production should be improved.

Abstract

In this study, surface modification of 2,2,6,6-tetramethylpiperidine-1-oxyl radical TEMPO-cellulose nanofibrils (TCNF) was obtained by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) and N–hydroxysuccinimide (NHS)-mediated system. The carboxylate groups on TCNF surface was replaced by conjugation of octadecylamine (ODA). The conversion of the carboxylate groups on CNF into amide I and II groups was confirmed by attenuated transform reflectance-infrared (ATR-FTIR) and elemental analysis study. Further, decarboxylation of TCNF at higher temperature was hindered by the presence of amide groups resulted in the higher thermal stability of TCNF as observed by thermogravimetry analysis (TGA). These results suggested the possibility of modifying surface negatively charged of TCNF with conjugated amine groups into thermally stable nanocellulose.

Abstract

Lubuk Kertang Village has the potential for mangrove ecotourism which is currently being developed as a source of income for the community's economy apart from fishermen and agriculture. Even the mangrove ecosystem in Lubuk Kertang Village has become a tourist icon for Langkat. Apart from mangrove ecotourism, Lubuk Kertang is also unique with its processed mangrove products in the form of foods such as mangrove dodol, jeruju crackers, and mangrove syrup. However, productivity is constrained by the availability of mangrove fruit which depends on the season. Moving on from this, it is necessary to carry out community service activities to provide education about the potential and benefits of mangrove waste in the form of stems, twigs, leaves, and fruit from other aspects. Namely that apart from being processed as food material, mangrove waste can also be processed into other high-value products, one of which is a natural dye. Activities carried out are in the form of socialization and education about the potential and benefits of mangrove waste as a natural coloring agent to the manufacturing process. Furthermore, the natural dyes that have been produced are applied in the coloring process through the ecoprint workshop/training. The media used are cloth/textiles, paper, sheepskin, and ceramics (mugs). The response of the community, represented by women from independent women farmer groups as well as some students of Madrasah Tsanawiyah and the Village Head was very good. Even some mothers from independent women farmer groups routinely continue to make ecoprints in the form of cloth, pashmina, and t-shirts. Their products have also been included in exhibition activities in Lubuk Kertang Village. The Head of Lubuk Kertang Village hopes that there will be sustainability from independent women farmer groups to make ecoprint products to increase income from the Lubuk Kertang community. Abstrak Desa Lubuk Kertang memiliki potensi ekowisata mangrove yang saat ini terus dikembangkan sebagai salah satu pemasukan sumber pendapatan ekonomi masyarakat selain nelayan dan pertanian. Bahkan ekosistem mangrove di Desa Lubuk Kertang menjadi ikon wisata Langkat. Selain ekowisata mangrove, Lubuk Kertang juga khas dengan produk olahan mangrovenya berupa makanan seperti dodol mangrove, kerupuk jeruju dan sirup dari buah mangrove. Namun produktivitasnya terkendala oleh ketersediaan buah mangrove yang tergantung dengan musim. Beranjak dari hal tersebut maka perlu dilakukan kegiatan pengabdian pada masyarakat untuk memberikan edukasi tentang potensi dan manfaat limbah tanaman mangrove baik berupa batang, ranting, daun dan buah dari aspek yang lain. Yaitu bahwa selain dapat diolah sebagai bahan pangan limbah tanaman mangrove juga dapat diolah menjadi produk bernilai tinggi lainnya, salah satunya sebagai pewarna alami. Kegiatan yang dilakukan adalah dalam bentuk sosialisasi dan edukasi tentang potensi dan manfaat limbah tanaman mangrove sebagai zat pewarna alami hingga proses pembuatannya. Selanjutnya pewarna alami yang telah dihasilkan diaplikasikan dalam proses pewarnaan melalui kegiatan workshop/pelatihan ecoprint. Media yang digunakan adalah kain/tekstil, kertas, kulit domba dan keramik (mug). Respon masyarakat yang diwakili oleh ibu-ibu kelompok tani wanita mandiri serta beberapa siswa Madrasah Tsanawiyah dan Kepala Desa sangat baik. Bahkan beberapa ibu-ibu dari kelompok tani wanita mandiri secara rutin terus membuat olahan ecoprint berupa kain, pashmina dan kaos. Hasil produksi mereka juga telah diikutserakan pada kegiatan pameran di Desa Lubuk Kertang. Kepala Desa Lubuk Kertang mengharapkan adanya keberlanjutan dari kelompok tani wanita mandiri untuk membuat produk-produk ecoprint dalam rangka menambah pemasukan dari masyarakat Lubuk Kertang.

Abstract

Microplastics are one of the pollutants that threaten aquatic ecosystems and have become the focus of research in recent years by environmentalists worldwide. In addition to harmful base materials, microplastics have hydrophobic characteristics, so chemicals such as Persistent Organic Pollutants can stick to microplastics and cause chemical pollution in aquatics. Siombak Lake is located in the coastal area of Medan City, and it is predicted to be a microplastic distribution channel to the aquatics. This study aimed to analyze the abundance of microplastics in water, sediment, and fish in Siombak Lake. Sampling was conducted from November 2021 – January 2022 at Siombak Lake. Water samples to be analyzed were added with 90 g NaCl, then filtered and separated visually using a microscope. Microplastic in the sediment is separated by drying, volume reduction, density separation, filtration, and visual sorting. Fish samples were dissected, and then the digestive tract content of fish was diluted with 10 ml of saturated NaCl. The abundance of microplastics obtained in waters ranged from 93-519 particles/m3, and the Number of microplastics in sediment ranged from 521-1481 particles/kg dry sediment, while the abundance of microplastics in fish samples ranged from 0-6 particles/individual.Keywords: Microplastic, Abundance, Coastal, Pollutant, Siombak Lake

Abstract

The waste product left over from pressing or extracting oil palm trunk (OPT) for sugar purposes is known as oil palm trunk bagasse (OPTB). This residue contains mainly vascular bundles and small amount of parenchyma. These materials are potentially utilized for making panel products such as particleboard (OPTBparticleboard). Objective of this study was to evaluate physical mechanical properties of OPTB-particleboard. For preserving the durability, this work was intended to apply 15% mixture of methyl methacrylate (MMA) cured with Styrofoam as the binder with a ratio (w/w) of 3:1. OPTB-particleboard was made according to the Japanese Industrial Standard (JIS A5908: 2003) with a target density of 0.75 g/cm3 and dimensions of 25 x 25 x 1 cm3. Hot pressing was a condition set at a pressure of 30 kg/cm2 and a temperature of 160 °C for 15 minutes. Physical and mechanical properties were tested according to JIS A 5908:2003 standard. The results showed that physical and mechanical properties of the OPTB-particleboard did not meet the standard. The characteristics of OPTB still easily absorb water even though MMA-Styrofoam should hinder water ingress. Additionally, the poor quality of the OPTB-particleboard was primarily due to the binder's inadequate composition. Optimum values reached when IB, MOR, and MOE were 0.026 MPa, 6.69 MPa, and 892 MPa, respectively. Based on the analysis of variance, it can be concluded that there is no influence on the bottom, middle and upper parts of the origin of the OPTB except for the MOR.

Abstract

This editorial is an opening remark of the first edition Journal of Sylva Indonesiana (JSI) containing the growth and development of the journal managed by Faculty of Forestry Universitas Sumatera Utara (“Fahutan USU”). In the first stage, “Jurnal Ilmiah Pertanian Kultura” published by Faculty of Agriculture USU has been targeted by faculty member of “Fahutan USU” for dissemination of their research results. This journal has been accredited by Directorate General of Higher Education in 2003 consequently its scope become specific, forestry science did not include therein. Hence, at that time, Program Study of Forestry Science under management of Faculty of Agriculture USU initiated the issuing of Peronema Forestry Science Journal in 2005 in order to accommodate scope of forestry science. Unfortunately the service and production of this journal become stagnant because most of the editorial staff pursued higher education in outside Medan city and the funding for publishing and printing vanished. In 2012, with the new spirit, Program of Forestry Science re-issued the new journal called “Foresta” Indonesian Journal of Forestry. It was a pity, the production process of this journal discontinued regarding to no submission of the manuscripts. All of the research results of undergraduate students of Program Study of Forestry Science have been uploaded into Peronema Forestry Science Journal in online version since 2014. In connection with establishment of organization structure of Faculty of Forestry completely, the publishing of JSI has been started in 2018 even though the editorial works of this journal has been begin since 2017, comprise call of paper, blind-review process, correspondence with the authors, layout and editing, including upload in the journal website. Supply of the manuscripts is provided not only from undergraduate research results of Faculty of Forestry’s students but also from the outside. With the commitment of the funding from the Faculty of Forestry USU, hopefully JSI can reach the target as the national accredited journal and it can achieve the status to be a reputation journal in the field of forestry in the future.
