Abstract

Keberadaan limbah rajungan dianggap sebagai permasalahan yang berpotensi mencemari lingkungan, salah satu limbah padat yang dihasilkan adalah cangkang dengan jumlah cukup banyak. Salah satu pemanfaatan limbah cangkang rajungan adalah dengan dijadikan sebagai tepung. Pemanfaatan limbah cangkang rajungan dilakukan sebagai upaya untuk mengurangi pencemaran lingkungan dengan cara mengolah limbah rajungan sebagai bahan tambahan pada ransum burung puyuh.Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif untuk mengetahui kandungan kalsium yang ada dalam pakan. Data yang didapat dari hasil penelitian disajikan dalam bentuk tabel kemudian dianalisis secara deskriptif untuk menarik sebuah kesimpulan hasil penelitian.Hasil penelitian menunjukkan kadar kalsium setiap formula pakan ternak burung puyuh yang berbahan cangkang rajungan menunjukkan nilai yang berbeda, perlakuan R2 (dengan tambahan tepung cangkang rajungan 25%) merupakan perlakuan dengan kadar kalsium tertinggi yaitu 0,45%, kadar kalsium untuk 2 perlakuan lain yaitu R0 (tanpa tambahan tepung cangkang rajungan) dan R1 (dengan tambahan tepung cangkang rajungaan 15%) masing-masing memiliki kadar kalsium 0,20% dan 0,28%. Pada penambahan tepung cangkang rajungan 25% diduga akan memenuhi nutrisi pada pakan burung puyuh, akan tetapi jika dibandingkan dengan nilai kadar kalsium pada SNI 01-3931-2006 yakni antara 2,50-3,50% maka semua perlakuan tidak ada yang memenuhi syarat. Penggunaan tepung limbah cangkang rajungan sampai level 25% belum memberikan perbaikan kadar kalsium pada pakan burung puyuh.Kesimpulan dari penelitian ini Pemberian tepung cangkang rajungan dengan level 25% tidak berpengaruh terhadap formula pakan ternak burung puyuh. Penggunaan tepung limbah cangkang rajungan sampai level 25% belum memberikan perbaikan kadar kalsium pada pakan burung puyuh. Adapun saran yang diberikan penulis adalah untuk penelitian selanjutnya bisa ditingkatkan level penggunaan tepung cangkang rajungan untuk perbaikan kadar kalsium pada pakan burung puyuh.

Abstract

Tuna fish has high content of protein. The purpose of food processing is to make a well preserve product, improving the taste and increasing economic value. Sterilization of canned tuna is an example of food processing to achieve the above purpose. A well preserve product must be free from the possibility of proliferation of microorganisms. The objective of this study was to investigate and evaluate the impact of medium used in canned tuna product on heat penetration speed during sterilization and to know the preference level by consumer.Determination of F0 value in this research refers to the protocol of Canadian Food Inspection Agency (CFIA) by using general method to analyse data, protein analysis followed Kjeldahl method and organoleptic examination used Friedman test. Analysis of effectiveness index was conducted to determine the best treatment. The experimental design used randomized single design with three kinds of treatments which were repeated 3 times for each observation. Results indicated that the fastest heat penetration was obtained by in brine product with 46 minutes sterilizatiion time, followed by in oil product with 62 minutes, then in brine + oil product with 65 minutes. Analysis of variance showed that treatment of medium usage provides a very significant impact on heat penetration (F count larger than F table 5 % and 1 %). Heat treatment also provides a significant impact on protein content (F count larger than F table 5 % and 1 %). Organoleptic examination showed that treatment gave significant effect on flavour and odor (F count larger than F table), but not significant on color (F count is smaller than F table). In conclusion, the fastest heat penetration was obtained by in brine product with 46 minutes sterilization time, followed by in oil product 62 minutes, then in brine + oil product with 65 minutes. Consumer preference and the best treatment in this research was obtained by in brine + oil product, followed by in oil product, then in brine product.

Abstract

Fish is a source of high protein and is a commodity that is prone to spoilage. One method to inhibit the decay process is by smoking. Smoking aims to reduce the water content of smoked fish so that the smoked fish can have a longer shelf life. One of the commonly smoked fish is mackerel (Rastrelliger brachysoma). This method of smoking mackerel in this study is using traditional smoking method with coconut shells as fuel. The purpose of this study was to determine the difference in water content in smoked mackerel based on different fish size according to SNI 2725:2013 regarding smoked fish. This type of research is quantitative experimental with the independent variable being the size of mackerel (A = size of mackerel 10 cm – 12 cm and B = size of mackerel 16 cm – 18 cm), the independent variable is water content, while the controlled variable is the type of fish and length of smoking time. Each treatment was repeated 5 times. The result of this study is that there are differences in water content of smoked mackerel based on different fish sizes, where Fcalculated (82,73) > from Ftable 5% (5,31) and small (A = size of mackerel 10 cm – 12 cm) and medium size (B = size of mackerel 16 cm – 18 cm) smoked mackerel meet the SNI 2725:2013 quality standard on smoked fish for the water content parameter, which is below the maximum value of 60% water content.

Abstract

Catfish (Clarias sp) is one type of fish that lives in fresh water and is widely cultivated because it has economic value. Several processing industries derived from catfish produce waste in the form of bones, heads, entrails, scales, and skin. Fishery waste can be used as a product, one of which is collagen. Collagen can be derived from the bones of freshwater fish such as catfish (clarias sp). Collagen is a fibrous protein that gives strength and flexibility to tissues and bones and plays an important role in other tissues including skin and tendons. Currently, care products containing collagen are in great demand by the public. Soap is a cleanser with water media. Soap is made in two ways, namely the saponification process and the oil neutralization process. This study aims to determine the effect of bone collagen substitution of catfish (Clarias sp.) on moisture content, pH, and foam stability and the effect of substitution of bone collagen of catfish (Clarias sp.) on transparent solid soap on organoleptic test results. The method in this study used RAL with variations of 0g catfish bone collagen substitution; 2g; 4g; 6g; 8g substituted in 100g transparent solid soap. The results of the catfish bone collagen soap were tested by analysis of water content, pH, foam stability, and organoleptic tests (color, aroma, foam, rough impression, and itching reaction). The research data were analyzed using Analysis of variance (ANOVA) followed by Tukey's test and nonparametric statistics, namely Kruskal Wallis, while the organoleptic test data were analyzed using the Friedman test with a significance level of 5%. The best treatment uses the De Garmo method. The results showed that the addition of catfish bone collagen had a significant effect on water content, pH, and stability of transparent solid soap foam, and the effect of the treatment of catfish bone collagen substitution on transparent solid soap, there was a significant difference in the organoleptic results of color, aroma, foam and a rough impression but there was no significantly different to the organoleptic results of itching reactions. The best treatment for adding catfish bone collagen to transparent solid soap was obtained in treatment P2 (4 grams of Catfish Bone Collagen) with organoleptic test parameters including color 7.20 (like), aroma 6.80 (like), foam 8.12 (very good). like), bad impression 7.00 (like), itching reaction 7.00 (like).

Abstract

Catfish (Clarias sp) is one of the freshwater fishery commodities that has superior value compared to other freshwater fish species, which have relatively fast growth, strong survival, and adaptability to their habitat. Feed is an important factor in fish farming. Mocaf flour is processed cassava flour that has been fermented and produced cassava flour. Black Soldier Fly (BSF) maggot larvae are omnivores (eating everything) such as fruit waste, vegetable waste, food scraps, bones, and meat, to animals that have become carrion. This study aims to determine the effect of mocaf flour and BSF maggot flour on pellet feed on the growth of catfish (Clarias Sp.) and to determine the best formulation between mocaf flour and BSF maggot flour on the growth of catfish (Clarias Sp.). The method used in this study was Completely Randomized Design (CRD) with 3 treatments and repeated 3 times. The results of the feed will be tested with variance using ANOVA at a 95% confidence interval and further tested using the Tuckey test and the de Garmo effectiveness index. Results Mocaf flour gives a good effect when mixed with maggot flour. A good percentage of feed in a mixture of mocaf flour and maggot flour is found in P1 treatment, namely by mixing 25% mocaf flour + 75% maggot flour produces an efficient feed composition and is used to grow in length and weight of catfish.
