Abstract

Abstract   Red palm oil is source of p carotene and vitamin E, while Tuna fish is source of omega-3 and 6. Diversification of palm oil and tuna fish oil can be used as food supplement. The utilization of high concentration of minor vitamin is one of strategy to increase the additional value of both oil and also to provide minor vitamin from local product in order to increase the healthy of the society. There was some research conducted on micro encapsulation process of red palm oil which is rich of P carotene, provitamin A, and provitamin E. And there was also research subjected to microencapsulated fish oil which is rich of omega-3. In this research we combined the microencapsutaion of both red palm oil and tuna fish oil through enzymatic cytolysis process. From the cytolysis process, we will got type of fatty acid which is rich of omega 3 and P carotene . The objective of the research were to study the activity of rice bran lipase as biocatalisator in the conversion of palm oil fatty acid into fatty acid which is rich of omega-3, and to develop the bioreactor for the enzymatic cytolysis for fatty acid production. The research result showed that optimum condition for the cytolysis process was the ratio of red palm oil tuna fish oil 3:1, temperature 40oC; reaction time 4 hours, where the yield of fatty acid has EPA and DHA concentration 35,92% and 5,65%, respectively. While the rate of the reaction was 619,67 mol/hour. Red palm oil is an alternative source of fatty acid which is rich of omega 3 (EPA and DHA), and it can be produced by enzymatic cytolysis by using rice bran lipase. Lipase enzyme of R Meithei found to be a good biocatalyst in the red palm oil and tuna fish incorporation process of the fatty acid which is rich of omega-3.   Key words: citolysis, red palm oil, tuna fish oil

Abstract

Abstract   Oil production process with fermentation is one of method to produce virgin coconut oil (VICO). In this research, fermentation process done with coconut extract fermentation method as substrate, with biocatalysator, are Rhyzopus oligosporus, Rhyzopus orizae, body of crab and bromelin enzyme from raw pineapple. Design which used is a completed blocked random design. Source of variation is comparison of starter and substrate. From research which has done by biocatalysator, the most effective is Rhyzopus oligosporus with comparison starter and substrate 0,75 : 1, with velocity agitation 150 rpm, produce efficiency 90,23 % test of peroxide number until five weeks keep is 2,7-4,4, acid number 0,02, iod number 8,1, this result is comformable with food oil standard.   Key words : coconut extract – fermentation – Virgin coconut oil (VICO)

Abstract

Abstract Freezing is one way of preserving food for maintaining the quality before consumption. Frozen foods which are now circulating in the supermarket are not given yet a tool to monitor whether the food is never experienced thawing (melting) for some period. In the frozen product that has undergone uncontrolled thawing will increase microbial content rapidly at increasing temperature 10 0C. In this study the temperature-time estimator tool manufactured for frozen beef products and shrimp. This estimator tool consists of citric acid and blue litmus paper. The response will appear in blue litmus paper that changes the color becomes red when positioned at the undesired temperature. In this study, the temperature-time estimator tool is made from citric acid 1.1%, cotton and litmus paper packed in cellophane. The response is influenced by the position of estimator tool and this tool-time temperature estimator can be applied for frozen beef products and shrimp. Keywords: beef, frozen, indicators, shrimp

Abstract

Kegiatan Kuliah Kerja Nyata (KKN) merupakan kegiatan lapangan bagi mahasiswa yang menempuh bagian akhir dari program pendidikan S-1. Universitas mempercayai bahwa program ini mampu mendorong empati mahasiswa, dan dapat memberikan sumbangan bagi penyelesaian persoalan yang ada di masyarakat. Tambak Lorok adalah tempat penjualan ikan segar baik dalam jumlah besar maupun secara eceran. Pada umumnya ikan yang dijual merupakan hasil tangkapan pada hari itu. Untuk maksud memperpanjang penyimpanan dan memenuhi kebutuhan konsumen ikan yang cukup besar, beberapa ikan dijual dengan cara diasap. Ikan diasap menggunakan tempurung kelapa yang sudah tua. Masalah yang dihadapi kelompok pengasapan ikan ini adalah umur simpan ikan asap, sehingga apabila dalam waktu tersebut ikan tidak habis, sisanya sudah tidak memiliki nilai jual, sehingga produsen mengalami kerugian. Tujuan dari kegiatan ini adalah peningkatan produksi ikan asap melalui metode asap cair dan memanfaakan sisa arang tempurung kelapa. Metode yang digunakan oleh tim KKN PPM meliputi penyuluhan dan pendidikan untuk memproduksi ikan asap yang higienis. Hasil dari kegiatan ini memberikan banyak pengetahuan tentang bahaya asap yang melekat pada pengasapan ikan dan manfaat briket. Dengan antusias masyarakat sekitar Tambak Lorok memberikan respon positif untuk menggunakan alat yang digunakan untuk menghasilkan asap cair dan briket. Kegiatan KKN PPM ini juga didukung oleh berbagai pihak Kecamatan, Kelurahan dan Karang Taruna.

Abstract

Crafts copper and aluminum metal is well known as the only craft villages featured in Bambu Kuning  District Boyolali which is the center of industry UKM need to be given guidance and training , especially for UKM that there is little need of such a helping hand for community service programs ( IbM ). IbM basic selection service programs to improve the quality and productivity of  the aluminum craft in which the earlier process of making traditional , manually ( using hand -made) in order to become more mechanical craft aluminum kitchen equipment especially produced more precise form, include : Improvement of the manufacturing process of aluminum kitchen utensils mechanically, Design a simple hydraulic press tools according to their ability to operate and care for craftsmen improvement of more uniform product specifications in order to look more attractive.The method offered on IbM activities provide training and guidance to craftsmen on how to operate the hydraulic press tools properly and correct , also perfect the shape of the product so that the resulting shape kitchen tools more precise, more improved quality and can be sold at a higher price also to the wider marketing and export between islands .
