Abstract

Apem is a traditional Indonesian food known to the public as a snack made from rice flour. This study aimed to determine the effect of partial substitution of rice flour with cilembu sweet potato flour on the characteristics of apem cake and to know the best partial substitution to produce the best characteristics of apem cake. The design used in this study was a completely randomized design with a partial substitution treatment of rice flour and cilembu sweet potato flour which consists of 6 levels such as: 0%:100%, 10%:90%, 20%:80%, 30%:70%, 40%:60%, and 50%:50%. The treatment was repeated 3 times to obtain 18 units of the experiment. The data were analyzed by analyzed of variance and if the treatment affected on the variable significantly, then continued with the Duncan Multiple Range Test (DMRT). The result showed that partial substitution of rice flour with cilembu sweet potato flour had a significant effect on the content of moisture, ash, protein, fat, carbohydrate, crude fiber, swelling power, criteria hedonic of color, aroma, taste, and overall acceptance and criteria skor of color, aroma, texture and taste. The partial substitution of 50% produced apem cake with the best characteristics with moisture content 29.12%, ash content 0.51%, fat content 3.13%, protein content 2.85%, carbohydrate content 64.43%, crude fiber content 6.29%, swelling power 55.30%, score of color yellow, strong cilembu sweet potato scented, soft texture, sweet taste and overall acceptance liked.

Abstract

This study aimed to determine the effect of okara flour and rice flour ratio on the characteristics of apem cake and to determine the right of okara flour and rice flour to produce apem cake with the best characteristics. The experimental design used in this study was a Completely Randomized Design (CRD) with treatment that is the ratio of okara flour with rice flour which consist of 5 levels there is ( 0% : 100%; 10% : 90%; 20% : 80%; 30% : 70%; 40% : 60% ). The treatment was repeated 3 times to obtain 15 experimental units. The data obtained were analyzed by variance test and if the treatment had a significant effect with observed parameters, it was continued with Duncan Multiple Range Test (DMRT). The result showed that the ratio of okara flour with rice flour had significant effect on water content, ash content, protein content, crude fiber content, swellability, hedonic test color, aroma, texture, taste and overall acceptance and scoring test such as color and texture. The addition 30% of okara flour with 70% rice flour ratio produces apem cake with the best characteristics with water content 38.42%, protein content 6.04%, crude fiber content 9.99%, ash content 0.71%, swellability 3.47%, the color was brown and liked, the aroma liked, the texture was soft and liked, the taste liked and the overall acceptance liked.

Abstract

This study aimed to determine the effect of breadfruit flour and pumpkin flour composition on the characteristics of brownies, and to get the best composition which resulting in the best characteristic of the brownies. The experiment was designed as a completely randomized design with breadfruit flour and pumpkin flour composition used as the treatments, those consisting of 5 treatment levels, namely: P0 (100%: 0%), P1 (90%: 10%), P2 (80%: 20%), P3 (70%: 30%), and P4 (60%: 40%). Each treatment was repeated 3 times to obtain 15 experimental units. The data were analyzed by using analysisof variance and for the treatment showed significant effect, it continues analized by using Duncan Multiple Range Test. Theresults showed that ratio of breadfruit flour and pumpkin had a significant effect (P<0,05) on ash content, protein content,fat content, crude fiber content, beta carotene content, aroma, taste, texture, color, and overall acceptability, however it did not affect the moisture content. The ration of breadfruit flour (60%) and pumpkin flour (40%) produced the best characteristics of brownies with water content of 24.42%, ash content of 2.28%, protein content of 9.54%, fat content of 21.09%, carbohydrate content of 42.29%, crude fiber content of 4.06%, beta carotene content of 6.27 mg/100g. Thesensory characteristics were hedonic color of color 0f 4.35, aroma of 4.70, texture of 4.50, and taste of 4.75. Scoring color of 2.80, aroma of 2.90, texture of 2.85, and taste 0f 2.90.

Abstract

Abstract Roasted Pig is a Balinese dish that is highly popular in the tourist area of Ubud, Gianyar. Although Roasted Pig can be found in various regions of Bali, Ubud is known as one of the most prominent places for serving this dish. However, variations in the implementation of hygiene and sanitation practices in each restaurant may affect the safety and quality of the food, potentially leading to contamination by pathogenic microbes such as Escherichia coli and Staphylococcus aureus, which can pose risks to consumer health. This study aimed to assess hygiene and sanitation conditions and to identify the presence and quantify the levels of E. coli and S. aureus contamination in Babi Guling meat. The research employs a descriptive design presented in tabular form, using a interview method and purposive sampling method from the ten highest-rated eateries on Google Review by 2024. The parameter includes the implementation of hygiene and sanitation practices by food handlers and on eating utensils, total microbial count, coliforms, Escherichia coli, and Staphylococcus aureus. The results showed that sanitation practices at roasted pig restaurants include 70% of producers using groundwater as the water source, with none conducting accredited water quality testing. Swab tests on the hands of the food handlers and on equipment from five producers revealed that 100% were positive for E. coli. Additionally, 30% of vendors handled roasted pig without wearing gloves, and 80% did not use clean work clothing. All roasted pig samples exceeded the maximum allowable limit for total microbial count set by the Indonesian Food and Drug Authority (BPOM) (< 1 × 10⁶ CFU/g) and 100% did not meet the requirement for E. coli in heat-treated meat products (< 1 × 10² CFU/g). However, all babi guling samples were still within the safe threshold for S. aureus (< 1 × 10⁴ CFU/g).These findings highlight the importance of supervision and education on the implementation of hygiene and sanitation practices in the traditional culinary business sector. Keywords: Babi Guling, E. coli, Hygiene and Sanitation, S. aureus Abstrak Babi Guling merupakan-salah satu pangan tradisional khas Bali yang sangat populer di kawasan wisata Ubud, Gianyar. Meskipun babi guling dapat ditemukan di berbagai daerah di Bali, Ubud dikenal sebagai salah satu tempat yang paling menonjol dalam menyajikan hidangan ini. Namun, penerapan higiene dan sanitasi yang berbeda di setiap rumah makan dapat memengaruhi kualitas dan keamanan makanan yang berpotensi tercemar oleh mikroba patogen seperti Escherichia coli dan Staphylococcus aureus, yang dapat membahayakan kesehatan konsumen. Penelitian ini memiliki tujuan untuk mengetahui kondisi higiene dan sanitasi, serta mengidentifikasi keberadaan dan jumlah cemaran E. coli dan S. aureus pada daging Babi Guling. Penelitian ini menggunakan Rancangan Deskriptif yang disajikan dalam bentuk tabel dengan pengambilan sampel menggunakan Teknik wawancara dan metode purposive sampling dari sepuluh warung makan dengan rating tertinggi di Google Review pada tahun 2024. Parameter yang diamati adalah penerapan higiene dan sanitasi pada menjamah dan alat makan, Total Mikroba, Koliform, Escherichia coli, dan Staphylococcus aureus. Hasil penelitian menunjukkan bahwa praktek sanitasi pada rumah makan penjual Babi Guling diantaranya 70% produsen menggunakan sumber air tanah, dan semua produsen tidak melakukan pengujian kualitas air yang terakreditasi, lalu hasil swab pada tangan penjamah makanan, dan peralatan untuk sampling lima produsen menunjukkan 100% positif E. coli, 30% pedagang mengambil Babi Guling tanpa menggunakan sarung tangan, dan 80% pedagang tidak menggunakan pakaian kerja yang bersih. semua Babi Guling melebihi prasyarat maksimum Total Mikroba yang ditetapkan BPOM (< 1 x 106 koloni/g) dan 100% tidak memenuhi persyaratan E.coli pada daging olahan dengan perlakuan panas (<1x10² koloni/g), namun semua Babi Guling masih dalam ambang aman persyaratan S. aureus (< 1 x 104 koloni/g). Temuan ini menegaskan pentingnya pengawasan, dan edukasi tentang penerapan higiene dan sanitasi di sektor usaha kuliner tradisional. Kata kunci: Babi Guling, E.coli, Higiene dan Sanitasi, S.aureus
