Abstract

Aromatic citronella contains highly bioactive components that are easily degraded during processing and storage. Their stability decreases due to heat, light, and oxygen exposure. Encapsulation is one method to maintain the stability of bioactive components. This study aims to determine the content of protein, solubility, and water holding capacity (WHC) of aromatic citronella extracted and encapsulated by various maltodextrin concentrations and foam mat drying temperatures of catfish bone powder. The experimental design in this study used a completely randomized design (CRD) with two factors. Temperature variations in this study were 70°C and 80°C, and maltodextrin concentrations were 10% and 15%. Statistical analysis was performed with two-way ANOVA and continued with the DMRT (Duncan's Multiple Range Test) test at the significance level α = 5%. Total protein of encapsulated aromatic citronella extract on catfish bone powder ranged from 17.24-27.34%, solubility ranged from 34.53-55.64%, and WHC ranged from 4.49 – 43.03%. Maltodextrin concentration significantly affected protein content and WHC. Drying temperatures significantly affected the solubility of catfish bone powder with the addition of encapsulated aromatic citronella.

Abstract

Natural dyes are alternatives to synthetic dyes as batik dyes. However, color results produced by natural dyes were not as good as synthetic dyes, hence mordant compounds were required. As a substitute for metal mordant, it was essential to have another alternative mordant, such as chitosan. This research was intended to analyze the color produced by various sources of natural dyes, betel nut; spurred mangrove (tingi) bark; baheda (jolawe) peel; mangrove bark; mahogany bark; and copperpod (jambal) bark, quantitatively by testing the value of color differences (ΔE) on variations of  the chitosan concentration and fabric dyeing. In conclusion, the use of chitosan could enhance the absorption of dye into the fabric. In a chitosan concentration of  10 g/L, betel nut reached an  ΔE value of 15.40; spurred mangrove 16.26; baheda peel 18.97; mangrove 10.87; mahogany 14.01; and copperpod 19.33. Furthermore, the test of fastness to sunlight with greyscale showed the value in range of 4-5 (good).

Abstract

The strategic plan for the development of the Semaki area is to develop regional-based economic, social and cultural communities with various training programs. One of which is handmade batik craftsmen who is in UKM Balai Agung Cendana Batik Tulis. The problems are high production costs and the length of production time in making batik. The purpose is to increase the knowledge and capacity of partners in producing batik with natural dyes by introducing natural dyeing technology so as to reduce the stages of the process so as to reduce production costs. Methods and approaches in implementing this activity are counseling and training. Community service activities at Balai Agung Cendana Batik Tulis were able to increase participants' knowledge in drawing motifs, wax painting, dyeing processes, and pre-mordanting with chitosan up to 100%. The batik training provided to the community was also able to improve the community's skills in drawing and painting batik up to 92% and the skills of dyeing fabrics with natural dyes and chitosan mordanting up to 98%.
ANALISA KARAKTERISASI BIO-OIL HASIL PIROLISIS LIMBAH BANNER DAN CAMPURAN DENGAN LIMBAH SERBUK GERGAJI Firmansyah, Lutfi; Mufrodi, Zahrul; Maryudi, Maryudi; Astuti, Erna; Ismanto, Deny

Abstract

Peningkatan limbah banner berbahan PVC dan serbuk gergaji dari industri kayu menimbulkan masalah lingkungan. Namun timbulan masalah tersebut terdapat potensi sebagai sumber energi alternatif. Penelitian ini bertujuan mengonversi kedua limbah tersebut menjadi bio-oil melalui proses pirolisis. Produk bio-oil kemudian diuji  karakteristik fisik serta kimianya. Proses dilakukan menggunakan jenis reaktor fixed-bed pada temperatur operasi 300–500 °C dengan interval 50°C. Analisis TGA digunakan untuk mempelajari dekomposisi bahan, sedangkan GC–MS untuk mengidentifikasi senyawa penyusun bio-oil.Hasil menunjukkan dekomposisi utama limbah banner terjadi pada 285 °C dan serbuk gergaji pada 338 °C dengan rentang optimum pirolisis antara 300–400 °C. Yield bio-oil menurun dari 22,34% menjadi 1,12% seiring kenaikan suhu, sedangkan syngas meningkat dari 10,47% menjadi 38,44%. Komposisi kimia bergeser dari senyawa ester pada suhu rendah menjadi fenolik dan aromatik kompleks pada suhu tinggi. Kondisi optimum tercapai pada 400 °C dengan densitas 1,07 kg/m³, viskositas 1,15 cP, dan nilai kalor 23,5 MJ/kg.Bahan baku dengan campuran 75% banner dan 25% serbuk gergaji menghasilkan bio-oil lebih stabil dengan dominasi senyawa aromatik oksigenat. Secara keseluruhan, pirolisis limbah banner maupun campuran dengan serbuk gergaji berpotensi sebagai solusi pengelolaan limbah. Baik berjenis plastik maupun biomassa yang memberikan hasil berupa bahan bakar alternatif.
