Abstract

This study aims to analyze the effect of pineapple ripeness level on yield and peeling time using a semi-mechanical peeler. The experimental method used pineapple samples from three levels of ripeness: green, greenish yellow, and yellow. The results showed that the use of a peeler increased peeling efficiency compared to the manual method, with shorter peeling time and better yield in green and greenish yellow pineapples.

The results showed that the use of a peeler increased peeling efficiency compared to the manual method, with shorter peeling time and better yield in green and greenish yellow pineapples. Although in yellow pineapples, the yield tends to be lower due to fruit damage during the peeling process.

Abstract

This study aims to evaluate the effect of varying yeast concentrations on the sensory quality of cassava tapai (Manihot esculenta) and black glutinous rice tapai (Oryza sativa var. glutinosa). The yeast concentrations used were 0.25%, 0.5%, 0.75%, 1%, and 1.5% based on the substrate weight. The parameters observed included taste, texture, aroma, and color, which were assessed organoleptically on the first and second days of fermentation. The results showed that yeast concentrations of 0.5% to 0.75% produced the best quality tapai in both cassava and black glutinous rice, characterized by a balanced sweet-sour taste, soft texture, and the distinctive aroma of tapai. At low yeast concentration (0.25%), fermentation was not optimal, while at higher concentrations (≥1%), over-fermentation occurred, marked by a bitter taste, excessively soft texture, and unpleasant odor. This study highlights the importance of using the appropriate yeast concentration in the tapai fermentation process to achieve optimal sensory quality.

Abstract

Susu kambing merupakan sumber olahan susu yang kaya nutrisi seperti kalsium, protein, dan asam lemak esensial dalam susu kambing menjadikannya bahan baku yang potensial untuk diolah menjadi berbagai produk, salah satunya adalah es krim. Es krim digemari oleh berbagai kalangan karena rasanya yang lezat dan teksturnya yang lembut. Penelitian ini bertujuan untuk menganalisis faktor-faktor internal dan eksternal yang memengaruhi kelangsungan dan pengembangan usaha es krim berbahan dasar susu kambing. Metode SWOT digunakan untuk mengidentifikasi Strengths (Kekuatan), Weaknesses (Kelemahan), Opportunities (Peluang), dan Threats (Ancaman) yang ada dalam usaha es krim susu kambing, melalui proses wawancara dan observasi lapangan. Disimpulkan bahwa usaha es krim susu kambing memiliki potensi yang cukup besar di pasar, terutama dengan meningkatnya tren hidup sehat dan pencarian produk-produk unik oleh konsumen. Namun, keberhasilan usaha ini sangat tergantung pada strategi pemasaran, edukasi pasar, dan manajemen rantai pasok yang efektif.

Abstract

Biji Jambu biji (Psidium guajava, L.) yang biasanya hanya dibuang kemudian dilakukan diversifikasi pangan dengan cara memanfaatkan nya sebagai bahan minuman yang sedikit mengandung kafein yaitu kopi yang bisa di konsumsi oleh semua kalangan orang yang mengalami gangguan lambung.. Penelitian ini bertujuan untuk mengetahui lama fermentasi terhadap kualitas kopi bubuk dari biji jambu bangkok dan mengetahui lama fermentasi terbaik dalam menghasilkan kopi bubuk dari biji jambu bangkok. Penelitian ini menggunakan Rancangan Acak Kelompok dengan perlakuan lama fermentasi 48, 72, 96 dan 120 jam. Parameter yang diamati adalah kadar air, kadar abu, padatan tidak larut dalam air, dan organoleptik. Berdasarkan hasil penelitian menunjukkan bahwa lama fermentasi berpengaruh terhadap kadar air, kadar abu, padatan tidak larut dalam air, dan uji organoleptik kopi bubuk biji jambu bangkok. Perlakuan lama fermentasi P3 (96 jam) adalah lama fermentasi yang tepat untuk kopi biji jambu bangkok dengan nilai kadar air (0,93%), nilai kadar abu (2,12%), nilai padatan tidak larut dalam air (0,83%), nilai organoleptik (3,93 / suka).

Abstract

Penicillin refers to a group of β-lactam antibiotics with high commercial value because it is precursor for semi synthetic antibiotics such as amoxicillin and ampicillin. It also has high antibacterial activity. Penicillin production in industrial scale uses large fermentation reactor which require optimum agitation. The present study was conducted to investigate the effect of agitation speed on penicillin production using Penicillium chrysogenum L112, which have high antibiotics activity against some bacteria. P. chrysogenum L112 which regenerated at 30°C for 7 days was suspended with distilled water. The suspension was inoculated to vegetation media to reach 2% (v/v) final concentration. It was then followed by activation at 28°C for 60 hours with 120 rpm agitation speed. The activated culture was inoculated to fermentation media to give 10% (v/v) final concentration in a 1 L fermenter at pH 7 and 28°C, aeration of 1 vvm, for 240 hours. Agitation speed was varied at 100, 150 and 200 rpm. Sample was collected every 24 hours and checked for its pH, dry cell weight, and antibiotics activity. The results of the present study indicate that agitation speed and time of incubation affected the P. chrysogenum ability to produce penicillin. The crude extract showed different effect when tested against different bacteria, which indicate different amount of penicillin produced. The best antibiotics activity was found at 150 rpm agitation speed, incubation time of 192 hours. The highest inhibition was found for Escherichia coli which showed 37 mm clear zone.
