Abstract

Research on antibacterial biodegradable plastic made from white sweet potato starch (Ipomoea batatas) has been carried out. The purpose of this study was to examine the effect of chitosan concentration on mechanical strength. The independent variables used were the concentration of chitosan, which was 0%; 0.01%; 0.03%; 0.05%; 0.07% (w/v). The mechanism of this research was carried out by dissolving various concentrations of chitosan in glacial acetic acid, with a concentration of 10% (w/v) white sweet potato starch dissolved in distilled water, then adding glycerol as a plasticizer at a gelatinization temperature between 80o-95oC, using a stirring speed of 75 rpm. The research results show that the addition of chitosan can increase the tensile strength value of the film mixed with chitosan and sweet potato starch, where the maximum tensile strength value obtained in this study is found in films with a concentration of 0.07% chitosan worth 0.0645 kgf/cm2 and a maximum value of % elongation of the starch mixture film white sweet potato and chitosan were obtained from films with a chitosan concentration of 0.07%, which is around 5.6%. Meanwhile, the white sweet potato plastic film without chitosan had tensile strength and elongation values of 0.0577 kgf/cm2 and 10.7%, respectively.

Abstract

Aromatherapy candles are one of the best-selling and popular products. Apart from being used as therapy by means of inhalers, it is also widely used as wedding souvenirs and souvenirs from certain areas by highlighting the distinctive aroma of that area. The Community Service Team chose an aromatherapy candle product as a product that has good business opportunities for mothers and young women in Mon Singet Hamlet, Kajhu Village, Aceh Besar District. Essential oils or essential oils used in making aromatherapy candles are lime and lemongrass, each of which has effectiveness for relaxation (anti-stress) and as a repellent or mosquito repellant. The results of the training show the enthusiasm of the participants in making aromatherapy candles with various attractive shapes and colors. In addition, the participants also understood the ingredients for making aromatherapy candles, their benefits and potential to be used as business opportunities.

Abstract

Manfaat minyak atsiri yang sangat banyak akan meningkatkan permintaan dalam jumlah yang banyak, sehingga untuk mendapatkan hasil yang optimal peneliti terus melakukan penelitian di bidang ini. Beberapa metode proses yang dapat digunakan untuk memperoleh minyak atsiri. Beberapa metode digunakan peneliti untuk mengetahui perolehan produk terbaik. Telah digunakan metode maserasi, dengan variasi beberapa pelarut sebagai pembanding, yang mana filtrat hasil maserasi selanjutnya distilasi untuk memperoleh minyak atsiri yang murni untuk mencari cara produksi minyak atsiri yang efisien dan menentukan pelarut terbaik untuk proses produksinya. Pelarut yang digunakan yaitu; Metanol, Etanol, n-Hexana dan juga Air. Tahapan metode maserasi, sampel sereh disiapkan 150 g dengan ukuran 1 cm, direndam oleh pelarut sebanyak 1 L dalam wadah tertutup selama 24 jam. Selanjutnya filtrat tersebut didistilasi untuk mendapatkan produk yang murni, kemudian dikarakterisasi menggunakan GC-MS. Hasil penelitian membuktikan bahwa minyak lebih banyak diekstrak oleh pelarut etanol dibandingkan pelarut yang lain, yaitu mencapai 23,31 g dan hasil uji GC-MS menunjukkan bahwa minyak sereh mengandung 25,75 % Geraniol. Sehingga disimpulkan Geraniol lebih larut dalam pelarut Etanol karena kepolaran senyawa -senyawa di dalam minyak sereh lebih dekat dengan kepolaran Etanol, sehingga jumlah rendemen yang dihasilkan lebih besar dibandingkan dengan ektraksi menggunakan selain Etanol.
