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.

Guava fruit has a shelf life of 2-7 days. Therefore, it is necessary to do a good post-harvest handling effort to inhibit or delay the process of ripening and damage to the fruit so that the fruit has a longer shelf life so as not to reduce its selling value. One way to inhibit or delay the ripening process and fruit damage is to coat the skin of the fruit surface with a wax coating method. This study aimed to study the effect of beeswax coating and storage time on the quality of guava fruit (Psidium guajava L.) crystals. This study used a factorial Completely Randomized Design (CRD) with two factors. The first factor is the immersion time (W) consisting of three levels, namely W1 = 20 seconds, W2 = 40 seconds, and W3 = 60 seconds. The second factor is storage time (L) which consists of 3 levels, namely 3 days, 9 days, and 15 days, with 2 (two) replications for each treatment combination. The data obtained were analyzed using ANOVA (Analysis of Variance) analysis. The results of this study showed that guava fruit which was treated by immersion for 20, 40 and 60 seconds had a very significant effect on vitamin C levels, guava fruit. For water content, fruit hardness, and total soluble solids of guava fruit based on the results of the variance have a significant effect. The duration of storage of guava fruit that has been coated with a layer of beeswax has a very significant effect on water content, fruit hardness, vitamin C content, total acid and total dissolved solids, while weight loss and water content have a significant effect. While the interaction between beeswax immersion time and guava fruit storage time did not show any difference.

Coffee is one of the plantations that are usually consumed in the form of drinks. Currently coffee has become part of the habits and culture of the community both in rural and urban areas. There are many types of coffee on the market, but the common ones are Arabica, Robusta and Liberica coffee. One of the main and biggest problems in processing coffee fruit into seeds is handling coffee fruit waste both solid waste (coffee skin) and liquid waste (coffee washing water and coffee fruit skin mucus). The skin of coffee fruit contains water, as well as sugar, tannins, minerals, fats, volatile compounds and other compounds. This study was conducted to determine the effect of the ratio of coffee and water rind and the concentration of sugar used to the quality of coffee fruit skin syrup produced. This study uses a Completely Randomized Design (CRD) with a Factorial pattern consisting of two factors. The first factor is the ratio of coffee skin and water (R), which consists of 3 levels 1: 1 (R1), 1: 1.5 (R2) and 1: 2 (R3). The second factor is the concentration of sugar (K), which consists of 3 levels namely 90% (K1), 100% (K2) and 110% (K3). The treatment combination is 3 x 3 = 9. Each treatment is repeated 3 times to obtain 27 experimental units. Analysis carried out on coffee fruit skin syrup included analysis of viscosity, pH, total acid, organoleptic (hedonic) and antioxidant activity. The results showed that the ratio of coffee and water rind significantly affected the aroma of coffee fruit skin syrup. The concentration of sugar has a very significant effect on the pH of coffee fruit skin syrup.
