Abstract

Gracilaria verrucosa merupakan jenis alga merah (rhodophyta) yang terdapat di pesisir Banten. Gracilaria verrucosa selain bermanfaat sebagai bahan pembuatan agar namun juga memiliki kandungan senyawa aktif antioksidan, nanopartikel perak maupun emas. Gracilaria verrucosa banyak terdapat di pesisir pantai Banten namun belum dimanfaatkan dengan baik maupun menjadi produk budidaya. Penentuan metode ekstraksi sangat penting untuk mengekstrak komponen aktif yang diinginkan. Ekstraksi berbantu gelombang ultrasonik  membutuhkan waktu dan jumlah pelarut yang lebih sedikit dibandingkan dengan ekstraksi konvensional sehingga diharapkan memiliki efektifitas yang lebih baik dibandingkan metode konvensional. Tujuan dari penelitian ini adalah untuk mengidentifikasi kandungan nanopartikel perak Gracilaria verrucosa dari pantai Anyer, serta mengetahui pengaruh ekstraksi berbantu gelombang ultrasonik dan maserasi terhadap kandungan total fenol. Waktu ekstraksi sonikasi divariasikan 15, 20, dan 25 menit. Hasil penelitian menunjukkan keberadaan kandungan nanopartikel perak yang ditunjukkan dengan perubahan warna ekstrak menjadi coklat gelap. Kadar total fenolik berbantu gelombang ultrasonik didapatkan sebesar 896,0722 mg GAE/g ekstrak dan untuk metode maserasi sebesar 834,2133 mg GAE/g ekstrak. Ekstraksi berbantu gelombang ultrasonik memiliki efektifitas lebih baik dibandingkan dengan metode maserasi.

Abstract

Tomat (Solanum lycopersium L) merupakan buah yang memiliki kandungan air yang tinggi, sehingga mudah mengalami kerusakan dan mengurangi masa simpan tomat. Coating film pada tomat dapat berfungsi untuk melindungi tomat dari kerusakan fisik dan kimia. Kitosan jamur tiram sebagai bahan dasar pembentukan coating film memiliki kelebihan yaitu bersifat kuat dan fleksibel, namun kitosan memiliki kelemahan, yaitu bersifat hidrofilik sehingga perlu penambahan bahan lain untuk memperbaiki karakteristiknya, yaitu dengan penambahan rice bran wax. Penelitian ini dilakukan melalui tahapan pelarutan kitosan dalam asam asetat, penambahan rice brand wax 20-50% (w/v), pembentukan coating film menggunakan metode grafting dengan bantuan gelombang ultrasonik pada temperatur 90°C selama 10-60 menit, dan pengaplikasian coating film pada tomat. Dari penelitian yang dilakukan diperoleh hasil tomat tanpa coating yang dianalisis selama 7 hari menunjukkan tanda pembusukan, sedangkan tomat dengan coating film tetap segar. Penambahan rice brand wax berpengaruh pada penurunan susut bobot tomat. Pada konsentrasi rice bran wax 1-5% menunjukkan bahwa coating film mampu mengurangi penyusutan berat tomat dibandingkan tanpa coating. Penurunan susut bobot tertinggi berturut-turut sebesar 7,88%; 7,71%; 5,8%; 4,57% dan 4,33%. Penambahan rice brand wax juga berpengaruh pada banyaknya gas etilen yang dihasilkan. Kadar gas etilen yang dihasilkan pada hari ke 7 dengan dan tanpa adanya pelapisan berturut-turut sebesar 7,89 dan 1,95 ppm.

Abstract

This study examines the effect of UV irradiation on the yield and physical characteristics of biodiesel from candlenut oil using a TiO2-K2O/natural zeolite composite. Natural zeolite was activated with KOH and impregnated with TiO2. The formed composite was analyzed with an X-ray diffractometer. Biodiesel was synthesized with candlenut oil to methanol molar ratio and catalyst loading (w/w oil) 1:4, 1:6, 1:8, and 2, 4, and 6%, respectively. The XRD analysis shows peak patterns of anatase and rutile TiO2, K2O, and zeolite. UV light can increase biodiesel yield, with the highest yield at 82.08% at oil to methanol molar ratio of 1:8 and a catalyst loading of 2%. The physical properties of biodiesel are in accordance with national standard SNI 7182:2015. GCMS results shows that the main components of fatty acid methyl ester from biodiesel are methyl oleate, methyl palmitate, and methyl linoleate.

Abstract

The study investigates the impact of surfactant concentration and mixing time on the physical properties and stability of emulsions in non-baffle mixing systems. Surfactants, known for their ability to reduce interfacial tension, play a pivotal role in enhancing emulsion stability by promoting uniform droplet dispersion and reducing coalescence. Experiments were conducted using varying surfactant concentrations (0, 5, and 10 mL) to evaluate their effects on key parameters such as density, viscosity, Reynolds number, emulsion height, and stability over time. The results revealed that higher surfactant concentrations significantly improved emulsion uniformity and stability, with the 10 mL concentration yielding the most consistent outcomes. However, the absence of baffles introduced challenges, including prolonged mixing times and stratification tendencies, underscoring the need for optimized mixing configurations. These findings have practical implications for industries reliant on stable emulsions, highlighting the importance of balancing surfactant concentration and mixing dynamics to achieve efficient and cost-effective processes.

Abstract

Chitosan, a biopolymer derived from chitin-rich biomass such as crustacean shells, has garnered attention for its biodegradability, biocompatibility, and wide-ranging applications. However, conventional chemical extraction methods relying on strong acids and bases pose significant environmental and safety concerns, often leading to molecular degradation and low product quality. This study explores the use of deep eutectic solvents (DESs) as a green alternative for chitosan extraction. DESs, formed from combinations of hydrogen bond donors and acceptors, offer tunable properties, lower toxicity, and recyclability. The article highlights the structural advantages, extraction efficiency, and environmental benefits of DESs over conventional methods. It also examines the integration of process intensification technologies, such as microwave and ultrasound-assisted extraction, to enhance yield and reduce energy consumption. The findings underscore DESs’ potential to produce high-purity chitosan while supporting sustainability goals and industrial scalability, offering a viable pathway toward eco-friendly biopolymer processing.
