Abstract

Abstrak. Plastik sebagai bahan pengemas mempunyai berbagai kelebihan namun tidak dipungkiri telah menyebabkan pencemaran terhadap lingkungan. Berbagai upaya untuk mengatasi pencemaran tersebut dan salah satunya adalah usaha menggantikan plastic dengan bahan yang ramah lingkungan. Edible film banyak diformulasikan dari berbagai bahan yang biodegradable. Polimer alam berbasis karbohidrat banyak dilirik sebagai sumber pembuatan film karena jumlahnya yang melimpah. Glukomanan merupakan polisakarida yang terdapat dalam umbi porang. Untuk pembuatan edible film, glukomanan dimodifikasi memjadi karboksi metIl glukomanan sebelum dicampur dengan karagenan. Sejumlah gliserol ditambahkan sebagai plastisizer. Pengamatan terhadap kesetimbangan adsorpsi uap air dilakukan dengan metode gravimetri pada kisaran kelembaban relatif 6,1 – 97%. Hasil menunjukkan bahwa film dengan konsentrasi gliserol yang lebih tinggi menunjukkan nilai kesetimbangan kandungan uap air yang lebih tinggi. Model kesetimbangan adsorpsi uap air yaitu persamaan Oswin digunakan untuk menggambarkan perilaku penyerapan air. Abstract. Various efforts have done to overcome the enviromental pollution and one of them is to replace plastic with environmentally friendly materials. Glucomannan is a polysaccharide found in porang tubers that can be a source for biodegradable edible film.. For the production of edible film, glucomannan was modified into carboxy methyl glucomannan before it was mixed with carrageenan. Glycerol was added as a plasticizer. The film was made by casting method. Gliserol was added to a mixed solution of carboxy methyl and carrageenan and then poured onto a mold before drying in an electrical oven. Observation of the equilibrium adsorption equilibrium was carried out by gravimetric method for different level of water activity (0.06 – 0.97) and temperature (30, 40 and 50 oC). The results showed that film with higher glycerol concentrations showed higher equilibrium moisture content. The equilibrium adsorption model, the Oswin equation, is used to describe the water absorption behavior with average error at 20,947 – 75,271%. Keywords: Carboxymethyl glucomannan-carrageenan film, water vapor equilibrium, Oswin equation.

Abstract

Abstrak. Pada penelitian ini, matrik hidrogel berbasis karagenan dibuat dan diaplikasikan untuk mengontrol pelepasan urea. Tujuan penelitian ini adalah mempelajari pengaruh konsentrasi glutaraldehid terhadap kecepatan pelepasan urea dan menyusun model kecepatan pelepasan urea. Film karagenan dimodifikasi secara kimiawi menggunakan ikatan silang atau crosslinking dengan glutaraldehid. Larutan karagenan 7 g/100 mL dicetak menjadi lembaran dan kemudian dikeringkan sehingga diperoleh lapisan film. Film direndam dalam larutan glutaraldehid dengan konsentrasi tertentu selama 2 menit dan dilanjutkan dipanaskan pada suhu 110oC selama 20 menit. Film yang dihasilkan dicuci dengan etanol dan dikeringkan. Pengisian urea ke dalam matrik film menggunakan metode difusi. Film kering direndam dalam larutan urea 0,074 g/mL selama satu jam dan selanjutnya dikeringkan. Kecepatan pelepasan urea dari film ke dalam media air dievaluasi berdasarkan data konsentrasi urea dalam cairan sebagai fungsi waktu. Berdasarkan hasil penelitian didapatkan bahwa semakin besar konsentrasi glutaraldehid (1-5%) menyebabkan urea yang tersimpan di dalam film semakin rendah. Model matematika yang diusulkan dapat mewakili peristiwa pelepasan urea dari film. Film berbasis karagenan yang dihasilkan berpotensi sebagai matrik pengontrol pelepasan urea. Kata kunci: crosslinking, glutaraldehid, hidrogel, karagenan, urea. Abstract. Controlled Release Matrices of Urea from Carrageenan: Effect of Glutaraldehyde Concentration. In this study, carrageenan-based hydrogel matrices were prepared and applied for urea controlled release. The aim of this work was to study the effect of glutaraldehyde concentration on the rate of urea release in water. Carrageenan films were chemically modified by crosslinking with glutaraldehyde. The films were prepared by casting the aqueous carrageenan 7 g/100 mL and then followed by drying. The films obtained were immersed in certain glutaraldehyde concentration for 2 min and then heated in the oven at 110oC for 20 min. The crosslinked films were washed using ethanol and then air-dried until the weight is constant. The dried films were immersed in a urea solution (0.074g/ml) for 1 hr and then dried. The rate of urea release was determined by measuring the urea concentration in water as a function of time of release. Results showed that higher glutaraldehyde concentration (1–5%) produced films with less urea content. The proposed mathematic model of urea release from the film can represent the rate of urea release. The prepared carrageenan-based film has the potential for controlling of urea release. Keywords: carrageenan, crosslinking, glutaraldehyde, hydrogel, urea. Graphical Abstract

Abstract

The availability of ruminant feed in terms of amount and nutritional adequacy is a common problem during the dry season. This condition is worst at the peak of the dry season (July - October) such as that faced by the Kelompok Tani Rukun Binantu of Rejosari in Bantul Regency - Yogyakarta. Pre-survey shows that the cost of feed in the dry season is uncompetitive to the price of cattle. This problem was solved by Program Kemitraan Masyarakat (PKM – UNS) 2020 with workshop in cattle feed preservation using silage and fermentation techniques. The silage technique is used in conventional-local forage, while the fermentation technique is aimed at preserving low-nutrient animal feed as well as improving digestibility and nutritional adequacy of the feed. Product’s monitoring and evaluation are carried out after 7 days for fermentation technique and 21 days for silage technique. The program is success in solving of Mitra’s problems and it is also one of Tri Dharma Perguruan Tinggi in technology transfer for rural communities.

CV Plantanesia is a home industry that produces nyamplung (Calophyllum inophyllum) seed oil known as Tamanu oil. The oil is usually used for skin care products and traditional medicines such as wounds, skin diseases, rheumatism, massage oil and itching medicine. Tamanu oil production leaves solid waste from the pressing process, which is cake/seed dregs and shells/skin of nyamplung fruit. This waste is generated in large quantities and has not been utilized, so it is only disposed of as garbage or just burned. Nyamplung seed shells contain resin phenolic compounds which is used as antioxidant, anti-inflammatory, anti-cancer and anti-microbial properties. It can be used for medical treatment. This project aims to provide training on processing waste nyamplung seed oil, especially the seed shells and their processing to become resin. This activity is carried out at CV. Plantanesia which is located in Tasikmadu, Jaten, Karanganyar. The project was implemented in various activities, such as counseling, focus group discussions and workshop for extracting resin from nyamplung shells. The resin extraction and optimization process condition were developed at the Chemical Engineering Laboratory, Faculty of Engineering, Sebelas Maret University. The experimental results are implemented in the workshop at the industry. From this activity, partners gain increased insight into the use of nyamplung seed shells. The resin product is expected to be useful as a high value by-product to increase the benefit of the industry, as well as to overcome the waste problem.Keywords: nyamplung seed shell, resin, tamanu oil
