Detection of Porcine DNA Residue in Various of Collagen Supplements
Collagen is the main protein that makes the connective tissue structure of vertebrates and can be found in interstitial tissue in almost all parenchymal organs with a function as a stabilizer and maintains the shape of these organs. Collagen can be divided into three major categories based on the source, collagen from cows, pigs and marine animals. Collagen derived from cows is extracted from skin and bones, but type of collagen derived from cows is takes of concern because of BSE or mad cow problems and is also reported to cause allergies in about 3% of the population. The alternative is using collagen from pork and marine animals. However, the use of pork collagen or contamination of pork collagen is prohibited for Muslims. The aims of this study to detection the residue DNA in collagen supplements and to identified the origin of DNA residue from non-halal materials.

The Effect of Storage Duration on Fruit Juices Made With or Without the Addition of Yeast Towards Its Alcohol Content
Fruit juice is a healthy beverage. However, we must be careful in handling or consuming such juice, especially in relation to its storage time. The Prophet of Muhammed PBUH in his hadith prohibits to drink fruit juices that have been stored for more than 3 days, as its legal status changes from Halal into Haram.In accordance with the development of science and technology, many methods could be used to measure alcohol content in a sample; such as Gas Chromatography-Mass Spectroscopy method (GC-MS). Therefore the objective of this research was to analyze the alcohol content of various fruit juices made with or without the addition of yeast and being stored within 1, 2, and 3 days using GC-MS, as well as its relation to the hadith Matn of the Prophet Muhammad PBUH regarding its law. Results showed that alcohol (ethanol) content of various fruit juices : red grapes, green grapes, dates, pomegranate and durian, made without the addition of yeast which stored for 3 days, in consecutive order were 0.524; 0.144; 0.214; 0.143 and 0.314% v/v. While alcohol (ethanol) content of various fruit juices : red grapes, green grapes, dates, pomegranate and durian, made with the addition of 10 g/L yeast were and stored for 3 days were 0.618; 0.921; 0.901; 0.575 and 1.202% v/v constitutively. Alcohol content of red grapes fruit juices of 0.524% v/v was the highest alcohol content (in juices) which is still Halal to be consumed
PENINGKATAN KESADARAN MASYARAKAT TERHADAP PRODUK HALAL DAN THAYYIB
Halal products generally can be seen from the Halal Certificate and or Halal Label on the product packaging. However, halal products often are sold with products that have not been guaranteed to the Halal in one place of display such as in supermarkets or the market, so it can’t be known the halalness of the product. To know halal and thayyib products, knowledge of foodstuffs are classified as halal and thayyib is needed. The purpose of this Community Service (PKM) activity is to socialize and educate related halal and thayyib products, the ingredients used in the product manufacturing process, and the halal critical point of each ingredient and or product. This form of activity is in the form of education and socialization about halal and thayyib materials and or products that enter, circulate, and be traded in the territory of Indonesia. To see the success rate and satisfaction of participants in this PKM activity are done through pretest, posttest, and questionnaire. The result of this PKM is that the participants can understand that the products that enter, circulate, and are traded in the territory of Indonesia are syubhat, so they must be halal certified. In addition, the participants of the PKM program can know and or distinguish what ingredients or products are halal or haram, as well as which are thayyib and which are not thayyib.Produk halal umumnya dapat dilihat dari Sertifikat Halal dan atau Label Halal di kemasan produk. Namun, produk halal seringkali masih dijual bersama dengan produk yang belum dijamin kehalalannya dalam satu tempat pajangan seperti di supermarket atau di pasar, sehingga belum dapat diketahui kehalalan dari produk tersebut. Untuk mengetahui kehalalan dan kethoyyibanan dari produk tersebut tentunya diperlukan pengetahuan tentang bahan–bahan makanan yang tergolong halal dan thayyib. Tujuan dari kegiatan Pengabdian Kepada Masyarakat (PKM) ini adalah mensosialisasi dan mengedukasi terkait produk halal dan thayyib, bahan-bahan yang digunakan dalam proses pembuatan produk, serta titik kritis kehalalan dari masing–masing bahan dan atau produk. Bentuk kegiatan berupa edukasi dan sosialisasi tentang kehalalan dan kethayyibanan bahan dan atau produk yang masuk, beredar dan diperdagangkan di wilayah Indonesia. Untuk melihat tingkat keberhasilan dan kepuasan peserta kegiatan PKM ini dilakukan melalui pretest, posttest dan kuesioner. Hasil dari PKM ini adalah para peserta dapat memahami bahwa produk-produk yang masuk, beredar dan diperdagangkan di wilayah Indonesia banyak yang syubhat, sehingga wajib bersertifikat halal. Selain daripada itu, para peserta program PKM tersebut dapat mengetahui dan atau membedakan bahan atau produk apa saja yang halal atau yang haram, juga mana yang thayyib dan mana yang tidak thayyib
DETEKSI DNA BABI PADA PRODUK SOSIS MENGGUNAKAN REAL TIME–POLYMERASE CHAIN REACTION (RT–PCR)
Sosis adalah salah satu produk olahan daging yang saat ini di Indonesia sudah diperjualbelikan sampai ke pinggiran kota bahkan ke desa-desa. Bahan baku sosis adalah daging sapi, ayam, ikan dan babi. Sampai saat ini harga daging sapi dirasakan oleh banyak konsumen masih sangat mahal. Namun, ternyata produsen sosis banyak yang menjual produknya dengan harga yang sangat murah. Kondisi tersebut dapat menimbulkan kecurigaan dari konsumen jangan-jangan ada penggantian atau pencampuran daging sapi dengan atau oleh daging babi. Berdasarkan hal tersebut, maka tujuan penelitian ini adalah untuk menguji kandungan daging babi (DNA babi) pada produk sosis yang dijual di pasar-pasar tradisional di Jakarta dan di gerai-gerai frozen food di perkampungan sekitar Jakarta. Pengujian DNA babi menggunakan metode Real Time Polymerace Chain Reaction (RT-PCR). Hasil penelitian menunjukkan bahwa semua sampel uji (10 sampel uji) dengan merek yang berbeda baik yang mencantumkan atau tidak mencantumkan logo halal MUI, semuanya tidak terdeteksi mengandung DNA babi
