Abstract

ABSTRACT. Minyak pala (Myristica fragrans Houtt) telah diketahui memiliki kemampuan antimikroba. Komponen dominan di dalam minyak pala adalah α-pinene dan sabinene. Daging sapi merupakan salah satu bahan pangan yang mudah rusak dan mudah terkontaminasi bakteri patogen. Oleh karena itu, bioaditif seperti minyak pala diperlukan agar daging sapi tidak mudah rusak dan terhindar dari cemaran bakteri patogen. Penelitian ini bertujuan mengetahui kemampuan antimikroba minyak pala (Myristica fragrans Houtt) dan komponen dominan (memiliki persentase tinggi) di dalam minyak pala (α-pinene dan sabinene) terhadap kualitas daging sapi. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial yang terdiri dari 2 (dua) faktor yaitu jenis bioaditif (minyak pala, α-pinene, sabinene, dan campuran α-pinene + sabinene) dan lama penyimpanan (1 hari dan 7 hari). Data yang diperoleh dianalisis menggunakan Analysis of Variance (ANOVA) dan uji Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa sabinene memiliki nilai TPC lebih tinggi yaitu 4,19 Log CFU/g pada lama penyimpanan 7 hari, dibandingkan dengan daging sapi yang direndam dengan α-pinene memiliki nilai TPC 3,19 Log CFU/g dan 3,55 Log CFU/g untuk minyak pala. Daging sapi yang direndam dengan menggunakan α-pinene dan minyak pala serta disimpan selama 7 hari, dapat menekan pertumbuhan Salmonella sp menjadi negatif, namun belum bisa menekan pertumbuhan bakteri patogen Coliform, Escherichia coli dan Staphylococcus aureus di bawah jumlah yang telah ditetapkan SNI 3932:2008. Secara organoleptik, daging sapi yang direndam menggunakan α-pinene memiliki aroma khas daging dan masih dapat mempertahankan warna kemerahan daging sapi. Bioaditif α-pinene dan minyak pala berpotensi untuk dikembangkan menjadi bioaditif alami pada daging sapi.  (Application of nutmeg essential oil (Myristica fragrans Houtt) and its major components (α-pinene and sabinene) as Bio-additives in Beef) ABSTRAK. Nutmeg essential oil (Myristica fragrans Houtt) has been known to have antimicrobial properties. The major components in nutmeg oil are α-pinene and sabinene. The addition of nutmeg oil in beef could protect beef from bacterial contamination. This study aims to determine the antimicrobial properties of nutmeg oil (Myristica fragrans Houtt) and its major components (α-pinene and sabinene) on beef quality. This study used a factorial Randomized Block Design consisting of two factors namely the types of bio-additives (nutmeg oil, α -pinene, sabinene, and a mixture of α-pinene and sabinene) and storage time (1 day and 7 days). The data was analyzed using Analysis of Variance (ANOVA) and the Duncan Multiple Range Test (DMRT). The results showed that sabinene had a higher TPC value of 4.19 Log CFU/g at 7 days of storage than α-pinene having TPC value of 3.19 Log CFU/g and 3.55 Log CFU/g for nutmeg oil. In addition, beef soaked using α-pinene and nutmeg oil and stored for 7 days, can suppress the growth of Salmonella sp to negative, but has not been able to suppress the growth of pathogenic bacteria Coliform, Escherichia coli and Staphylococcus aureus below the amount set by SNI. 3932:2008. Based on the results of organoleptic test, beef marinated using α-pinene has a more distinctive aroma of meat and could maintain the reddish color of the beef. Overall, α-pinene and nutmeg oil are potential to be developed as natural bio-additives in beef.

Abstract

This research aims to utilize of tofu liquid waste (Whey) into a more economical product in the form of nata de soya . This research uses a complete randomized design, which is consists of two factors, namely sugar (6% , 8% and 10%) and ammonium sulfate (0.3% , 0.5% and 0.7%). The observed parameters included yield, thickness, compressive strength analysis, crude fiber and organoleptic. The analysis results showed that sugar concentration and ammonium sulfate concentration significantly different to the yield, thickness, crude fiber, compressive strength and organoleptic. This research results showed that sugar and ammonium sulfate concentration influence significantly different to the thickness, crude fiber, compressive strength and organoleptic and not significantly different to the yield of nata de soya. The higher the sugar concentration and ammonium sulfate are used, the higher the yield, thickness, compressive strength, crude fiber produced. The best results obtained in the treatment of 10% sugar concentration and 0.7% ammonium sulfate.

Abstract

Asam sunti is a product of bilimbi (Averrhoa bilimbi L.) fermentation, traditional ingredient from Nanggroe Aceh Darussalam, used as flavor, particularly to provide sour taste and specific aroma in Acehnese cuisine. Scientific studies of asam sunti are relatively limited, while study of change on physical and chemical characteristics of asam sunti does not exist. The objective of this research was to study the change of physical characteristics of bilimbi during fermentation. This study used explorative laboratory design. Asam sunti was produced in laboratory scale with three times repetition and sample was taken three times in stages, i.e., before sun-drying and salting (stage 1), after repeated sun-drying and salting (stage 2), and fermentation for 1 month (stage 3). Parameters analyzed on physic characteristics included aw, texture and color. Significant change on physic characteristics were found during the processing of bilimbi to become asam sunti. The value of aw of the bilimbi was found to decrease after processing (sun-drying and salting) and fermentation for 1 month. Texture of the bilimbi increased at stage 2 and decreased at the last of fermentation. The colour of the bilimbi changed from green to brown after the whole processing (salting, drying and fermentation).

Abstract

Abstrak.  Masam keueng (asam pedas) merupakan masakan tradisional khas daerah Aceh, namun tiap daerah memiliki komposisi yang berbeda-beda. Penelitian ini bertujuan untuk mengetahui cara pembuatan bumbu masam keueng instan dalam bentuk bubuk dan untuk mendapatkan kondisi pengeringan dan formulasi bahan yang tepat. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK Faktorial) dengan 2 faktor. Faktor pertama yaitu kondisi pengeringan (P) dengan 3 taraf yaitu P1 (T = 50 oC; t = 9 jam), P2 (T = 60 oC; t = 6.5 jam), P3 (T = 70 oC; t = 4.5 jam). Faktor kedua yaitu formulasi bahan (F) dengan 3 taraf yaitu F1 = Formulasi bahan lengkap (asam sunti, cabai rawit, bawang merah, bawang putih, kunyit, dan lada), F2 = Formulasi bahan tanpa bawang putih (asam sunti, cabai rawit, bawang merah, kunyit, dan lada), dan F3 = Formulasi bahan tanpa lada (asam sunti, cabai rawit, bawang merah, bawang putih, dan kunyit). Setiap perlakuan diulang sebanyak 3 kali ulangan sehingga diperoleh 27 satuan percobaan. Hasil penelitian menunjukkan bahwa kondisi pengeringan (P) berpengaruh nyata (P≤0,05) terhadap kadar air, uji hedonik warna dan rasa masam keueng (P≤0,05) yang dihasilkan. Sedangkan interaksi keduanya berpengaruh tidak nyata (P0,05) terhadap kadar air, kadar abu dan hedonik aroma masam keueng. Perlakuan terbaik diperoleh pada perlakuan bumbu masam keueng dengan kondisi pengeringan dengan suhu pengeringan 50ᵒC dan lama waktu pengeringan 9 jam serta menggunakan variasi formulasi bahan lengkap (P1F1). Abstract. Masam keueng is a traditional cuisine typical of Aceh, but each region has a different composition. This study aimed to find out how to make instant masam keueng powder and to get the right drying conditions and ingredients formulation. This research used a Randomized Block Design (Factorial Random) with 2 factors. The first factor was the drying condition (P) with 3 levels which was P1 (T = 50 oC, t = 9 hours), P2 (T = 60 oC, t = 6.5 hours), P3 (T = 70 oC; t = 4.5 hours). The second factor was ingredients formulation (F) with 3 levels which was F1 = complete ingredients formulation (sunti acid, cayenne pepper, onion, garlic, turmeric, and pepper), F2 = non-garlic ingredients formulation (sunti acid, onion, turmeric, and pepper), and F3 = non-pepper ingredients formulation (sunti acid, cayenne pepper, onion, garlic, and turmeric). Each treatment was repeated 3 replicates so that 27 units of experiments were obtained. The results showed that drying condition (P) had a significant effect (P≤0,05) on water content, hedonic color and taste test of masam keueng. While the interaction of both effect had no significant effect (P0,05) on the water content, ash content, and hedonic flavour of masam keueng. The best treatment was obtained on the treatment of instant masam keueng powder made with drying condition 50 ᵒC and 9 hours and using complete ingredients formulation (P1F1).
