Abstract

Fermented Virgin Coconut Oil (VCO) is a processed oil where the manufacturing process uses baker's yeast, is easy to make and has simple equipment. The high content of lauric acid and vitamin E is beneficial for skin health, so it is often used as a raw material for making soap. One way to improve the function of VCO is the fortification process with dragon fruit which contains high antioxidants. This activity aims to increase community entrepreneurial interest by utilizing local potential into health and beauty products so that it can improve the family economy. Coconut and dragon fruit are the main raw materials for VCO and VCO soap which are easy to find in Sabila Village, Mallawa District, Maros Regency. Community service activities (PKM) begin with counseling/lectures on sterilization techniques, packaging methods and online product marketing. Followed by training on how to make VCO by fermentation and VCO soap with fortified dragon fruit extract. The results of the activity showed the enthusiasm of the participants during the discussion and the results of the pre- and post-test evaluation showed an increase in participants' knowledge about VCO and VCO soap by 78.0% after the training.

Abstract

Cocoa (Theobroma cacao L) production in Indonesia based on data from the Central Statistics Agency (BPS) for 2020 reached 720.66 thousand tons and continues to increase every year. Increasing cocoa production can cause cocoa waste to increase as well. Cocoa waste handling can be overcome by producing bioethanol as a way to reduce the amount of waste produced. This study aims to utilize cellulose compounds from cocoa fruit waste in the production of bioethanol through several stages, namely delignification, enzymatic hydrolysis by cellulase enzymes and the fermentation process with the help of Zymomonas mobilis bacteria. The results showed that the lignin level decreased by 19.5%, the hemicellulose level decreased by 6.87% and the cellulose level increased by 27.45%. Hydrolysis and fermentation stages were analyzed using the response surface method (RSM) to obtain optimum conditions. Cellulose can be optimally hydrolyzed using a pH buffer of 2 and a temperature of 30°C with a glucose concentration of 21,703 mg/mL. The fermentation process can be carried out at optimum conditions using a fermentation medium pH 10 with an incubation time of 168 hours. The bioethanol level was analyzed using a refractometer and gas chromatography (GC) with a yield of 8.43% (v/v).

Abstract

Cassava is one of the most widely produced agricultural products in Indonesia with cassava peel waste of 20%. Cassava peel contains carbohydrates and stores a high cellulose content so that it has a potential to be a bioethanol. This study aims to utilize cassava peel waste for bioethanol production with an alkaline pretreatment process, cellulase enzyme hydrolysis and fermentation by using Zymomonas mobilis bacteria. Alkaline pretreatment with 14% NaOH is used to hydrolyze lignocellulose. The hydrolysis optimization process enzymatically applies the Surface Response Method (RSM) to determine the optimum conditions at hydrolysis pH in the range of 2-10 and hydrolysis temperature in the range of 30-70 °C by analyzing glucose levels using the Dinitrosalicylic Acid (DNS) method and UV-vis spectrophotometry instruments. Surface Response Method (RSM) is likewise implemented to decide the greatest conditions of the fermentation process. The pH measurement ranges 2-10, and fermentation time takes 6 to 168 hours. Based on the results of research, it results a lignin content of 6.68% (b/b), cellulose content of 58.4% (b/b), and hemicellulose content of 27.3% (b/b). The optimum conditions of the hydrolysis process obtained an optimum glucose level of 9.22mg/mL at pH 2 and a hydrolysis temperature of 50°C. The optimum conditions of the fermentation process use Zymomonas mobilis at pH 6 while fermentation time takes 168 hours analyzed using a refractometer produced a bioethanol content of 37.75% (v/v) and a gas chromatography produced a bioethanol content of 54.94% (v/v).

Abstract

Kabupaten Pinrang adalah salah satu kabupaten di Sulawesi Selatan yang terkenal akan kelimpahan kekayaan hayati seperti kacang tanah, kakao, dan kelapa. Ketiga komoditas ini bila diolah melalui tahap fermentasi maka dapat menjadi bioproduk pangan yang berpotensi tinggi dan berkualitas. Fermentasi adalah proses tranformasi kimia substrat organik dengan memanfaatkan aktivitas enzim dari mikroorganisme. Kacang kedelai dan kacang tanah yang difermentasi serta penambahan ragi Rhizopus sp. menghasilkan bioproduk pangan yang dikenal sebagai tempe kalangka yang bermanfaat mencegah penyakit kanker payudara dan jantung koroner. Larutan palape dari limbah air kelapa dan kakao menjadi media asam yang mempercepat pertumbuhan ragi tempe. Nata de coko tinggi kandungan serat dapat meningkatkan kesehatan pencernaan. Metode pembuatan produk tersebut mudah untuk diterapkan. Kegiatan ini bertujuan memberikan pengetahuan akan cara pembuatan tempe, larutan palape dan nata de coko skala home industry, serta menumbuhkan kesadaran berwirausaha yang dapat memperbaiki taraf ekonomi keluarga di Kelurahan Tiroang, Kabupaten Pinrang. Langkah awal yang dilakukan yaitu mensurvei lokasi dan pembuatan ketiga produk dalam skala laboratorium. Pelaksanaan kegiatan dimulai dengan sesi penyuluhan materi manfaat ketiga produk beserta cara pembuatan desain pengemasan yang baik, dan diakhiri dengan sesi diskusi. Kegiatan ini dihadiri oleh target PKM, yaitu kaum ibu rumah tangga serta perwakilan daerah setempat. Kegiatan berlangsung dengan lancar dimana para hadirin mengikuti dengan seksama dan penuh antusias baik dalam sesi diskusi dan praktik. Survei data kegiatan melalui uji pre-test dan post test yang menunjukkan peningkatan pemahaman peserta terkait pelatihan yang diberikan. Diharapkan, kegiatan ini meningkatkan pemanfaatan komoditi lokal secara optimal.
