Burgo merupakan salah satu menu makanan dengan bahanbdasar tepungktapioka danktepung beras kemudian dibentuk dengan cara digulung. Penelitian ini bertujuan untuk menentukan perlakuan suhu dan waktu pengovenan terbaik pada pembuatan bumbu kaldu burgo instan. Penelitian ini menggunakan analisis Rancangan Acak Kelompok dengan 2 faktor. Faktor I suhu pengeringan terdiri dari 3 level (60?, 80?, dan 100?) dan faktor II lama pengeringan terdiri dari 3 level (6 jam, 9 jam, 12 jam). Parameter pengamatan meliputi warna, total padatan terlarut dan organoleptik. Hasil penelitian dengan perlakuan waktu dan suhu menunjukkan perbedaan signifikan terhadap nilai total padatan terlarut. Total padatan terlarut yang diperoleh mengalami peningkatan, sejalan dengan bertambahnya waktu dan suhu pengovenan dan berpengaruh nyata terhadap waktu dan suhu pengovenan. Berdasarkan tabel hasil pengamatan jumlah tanggapan yang benar untuk warna, rasa, aroma, dan kenampakkan adalah 18, 18, 18, dan 19. Sedangkan berdasarkan tabel binomial diperoleh minimum tanggapan yang benar pada taraf 5% adalah 18, sehingga sampel yang tidak berbeda nyata pada warna (suhu 80? selama 12 jam), rasa (suhu 80? selama 9 jam), aroma, dan kenampakan (suhu 100? selama 6 jam). Hasil penelitian terbaik terdapat pada perlakuan yang menggunakan suhu 80? selama 12 jam dengan rerata total padatan terlarut 42,35 mg/L, dan hasil organoleptik mendekati sampel burgo pasaran pada warna (kekuningan) dan aroma

Karakteristik Sensoris Chikuwa dengan Perbedaan Bahan Baku Surimi Ikan

Increased production of aquacultured freshwater fish, such as Pangasius pangasius, Oreochromis niloticus, and Clarias batrachus, wich have low commercial value as potential alternative raw materials for surimi. This study aimed to determine the sensory characteristics of chikuwa produced using different raw materials of surimi and increase the diversity of processed fishery products that are highly nutritious with recommended physical quality. This research used the randomized block design (RBD) method with three repetitions. The treatment used were the difference in raw materials of surimi, P1 (Pangasius pangasius), P2 (Oreochromis niloticus) and P3 (Clarias batrachus). Parameters in this research included physical analysis of surimi (gel strength), chemical analysis of surimi (protein content and moisture content), and chikuwa sensory analysis. The results showed that Pangasius pangasius had a significant effect on surimi gel strength, surimi protein content and surimi water content, but had no significant effect on Oreochromis niloticus and Clarias batrachus. Based on the chemical analysis results, all raw materials for surimi have met the standard of SNI 01-2694-2013 except for Pangasius pangasius surimi protein (11,94%). Different raw materials of surimi had a significant effect on the appearance, taste, color, and texture of the organoleptic test. However, it had no significant effect on the chikuwa aroma parameters. Chikuwa (P1) produced the best characteristics from an organoleptic.

Perendaman Pempek dengan Larutan Kitosan sebagai Edible Coating dan Pengaruhnya terhadap Umur Simpan

Pempek yang disimpan pada suhu ruangan memiliki umur simpan yang relatif singkat dan mudah mengalami kemunduran mutu produk. Pada penelitian ini pempek dilapisi oleh larutan kitosan 2% dengan perbedaan waktu perendaman (0, 10, 20, 30 menit) guna mengetahui pengaruh larutan kitosan sebagai coating pempek terhadap lamanya penyimpanan pempek pada suhu ruangan. Metode penelitian menggunakan rancangan split plot utama dengan 2 faktor perlakuan dan tiga kali pengulangan. Faktor perlakuan meliputi perbedaan waktu penyimpanan pada suhu ruangan (T0 = 0 hari, T1 = 2 hari, T3 = 3 hari, T4 = 4 hari) dan waktu perendaman pempek pada larutan kitosan (R0 = 0 menit, R1 = 10 menit, R3 = 20 menit, R4 = 4 menit). Untuk parameter pengamatan berupa kadar air, derajat keasaman (pH), kadar protein, Total Plate Count (TPC), Total Volatil Base (TVB), serta uji organoleptik. Hasil penelitian diperoleh nilai kadar air, pH, kadar protein, TPC dan TVB berpengaruh nyata terhadap kedua faktor perlakuan (T dan R). Begitu juga interaksi antara kedua faktor perlakuan berpengaruh nyata terhadap nilai pH, TPC dan TVB. Hasil Uji Kruskal Wallis waktu perendaman larutan kitosan sebagai coating pempek dengan nilai sensori pempek berpengaruh tidak nyata terhadap rasa pempek, namun berbeda nyata terhadap parameter tekstur, kenampakan, aroma, maupun warna pempek.

Pengaruh Waktu Penyangraian Beras terhadap Komponen Bioaktif pada Bekasam Ikan Nila (Oreochromis niloticus)

The objective of this research was to determine the effect of rice roasting time on bioactive compounds in bekasam from tilapia. This research used a Randomized block Design with four treatments. The treatments were the production of bekasam used rice (as a control) and rice with roasting time (0, 5, 10, 15 minutes). The parameters observed were acidity level (pH), lovastatin, peptide, and n-amino contents. The results of this study indicate that, roasting rice had a significant effect on the lovastatin content (54.35-57.73 ppm), where the highest lovastatin content was bekasam was produced by rice treatment (control). Rice roasting gived no significant affect to the pH value (6.12-6.35), peptide (9.24%-14.28%), and n-amino (0.014%-0.028%). Based on results of the research, fermentation bekasam process of tilapia fish with rice and rice roasting in the vacuum packaging has not been perfect.

Evaluasi Fisik Sediaan Krim Tabir Surya dari Bubur Rumput Laut Kappaphycus alvarezii dan Turbinaria conoides

Seaweed is one of the aquatic commodities which has many bioactive compounds. This bioactive compound is widely used in the cosmetic industry. In the cosmetic industry, usually has only one species of seaweed was used. The use of a combination of two seaweeds has not been widely used, therefore this study aims to determine the best sunscreen cream from the physical evaluation results of Kappaphycus alvarezii and Turbinaria conoides. The stages in this study were the making of seaweed porridge, formulation of sunscreen cream, and physical evaluation which included homogeneity, consistency of cream, cycling test, and organoleptic. In the homogeneity observation and cycling test, it was found that all treatments (cream concentration 0%, 10%, 20%, and 30%) had homogeneous and stable properties. The best cream consistency results were found in cream with 30% concentration (370x10–1). In organoleptic observations (appearance, color, and aroma) all creams with the addition of seaweed (cream concentration 10%, 20%, and 30%) were not significantly different. However, when compared to cream with 0% concentration, the results were significantly different. In this study, the sunscreen cream with the addition of 30% concentration of the combination of K. alvarezii and T. conoides is the best cream.

Pengaruh Lama Presto dan Konsentrasi Natrium Bikarbonat (NaHCO3) terhadap Karakteristik Tepung Tulang Ikan Tenggiri (Scomberomorus commerson)

Most fish processing industries only use fish meat as raw material for industry. Whereas fish bones are contain high mineral content needed by the human body and can be utilized as high calcium fishbone meal. Fishbone meal in this reaseach was made from waste from the fishery industries in Tanjungpinang, Riau Islands. Mackerel fishbone meal was made in several steps consist of preparation of raw materials, boiling of fishbones, washing and cleaning of the bones, presto processing of fish bones with the addition of sodium bicarbonate (NaHCO3), drying, siege and sieving. The purpose of this study is to determine the effect of presto duration and concentration of NaHCO3. This research was conducted by the factorial randomized block design method (RAKF) with two factors: duration of presto (2 hours (P1) and 4 hours (P2)) and concentration of NaHCO3 (0% (N1), 1% (N2) and 2% (N3)). The results showed that the duration of presto treatment and the concentration of sodium bicarbonate (NaHCO3) had a significant effect on the 5% level of yield but not significant on calsium content. The best results showed on 2 hours presto with addition NaHCO3 1%. The best treatment was used as a sample to measure the chemical characteristics of mackerel fish bone meal. Fish bone meal obtained 4.86% water content, 69.84% ash content, 3.72% protein content, 17.21% fat content, 12.56% phosphorus content, and 0.46% crude fiber. The chemical content of fishbone meal has been appropriate with Indonesian Nasional Standard.
