The laboratory is a closed room or open room as a place for conducting experiments and research. One understanding when laboratory research is important to master is the management of samples, especially wet samples. One sample sample that requires special handling is a sample of pig. The management of samples, especially samples of unclean ingredients, do not yet have clear references so that they become a big dilemma and become uneasy with Muslims if they are not managed properly. The method used in writing this article is literature study, discussion and study. The results include laboratory layout, organizing laboratory management, and retrieval techniques as well as handling laboratory pig samples. In general, handling pig samples on a laboratory scale must be done with extra caution, detail, and aseptism
The good food for consumption by a human is the food halal and tayyib. Halal is free from haram raw material, and tayyib is free from chemical or biological contamination, etc. Thayyib food, in other words as safe food based on food safety standards. Meanwhile, meat-based food, food safety standards start from the Slaughterhouse. The Slaughterhouse that registered as a large government slaughterhouse and a center for slaughtering livestock to be applied to the community is one of the benchmarks for standardizing meat safety. The purpose of this study was to determine the feasibility of slaughterhouses in the city of Bandung. The results of the study show that there are two slaughterhouses that are registered as government slaughterhouses and are a source of halal meat and have national standards. This study uses a type of field observation, research conducted in real life. The conclusion Government Slaughterhouses, namely Cirangrang and Ciroyom slaughterhouses, are clarified as proper slaughterhouses and have operating permits from the local government. The enumerators and slaughterhouse employees have received training and are regularly monitored by the local government. So that the Slaughterhouse can be assumed as a slaughterhouse that has appropriate standardization based on food safety. Slaughterhouse has stable sales and has consumers who become regular customers. Several meat brokers and traders in wholesale and traditional markets source their meat for sale from these abattoirs. So based on the results of observations, the source of food used by snack producers circulating in the city of Bandung should not be contaminated by pork and appropriate based on the source of the meat.
Macodes petola (Blume) Lindl. has an attractive of leaves veins motif with letters pattern, so it has a high economic value. Tissue culture technique is reported as the best way of plant propagation in short time. BAP (6-Benzyl Amino Purine) has a role in stimulating shoot growth with a certain concentration. The purpose of this study was to determine the effect of Various Concentration BAP (6-Benzyl Amino Purine) on Orchid Growth (M petola (Blume) Lindl.) in vitro. This study used a completely randomized design (CRD) with 4 concentration BAP levels (0; 0.5; 1; 1.5 ppm) with 3 replication. Based on the results of the study, it showed that up to 60 DAP (Day After Planting) the composition of the media with a concentration of 0 ppm BAP had a higher average value for the increase in the stem height, number of shoots and number of roots, namely 1.77±0.798 cm, 2.4 ± 1,528 shoot and 2.4 ± 2,082 root. In contrast to the concentration of 1.5 ppm at this concentration it has a low average value the parameters of stem height, number of shoots and number of roots.
Sterilisasi merupkan salah satu faktor penting keberhasilan kultur in vitro. Tujuan dari penelitian ini adalah untuk menentukan metode sterilisasi yang optimum dan tepat untuk perbanyakan porang secara in vitro. Eksplan yang digunakan adalah umbi dan bulbil. Penelitian ini melakukan lima model perlakuan sterilisasi dengan eksplan berupa umbi dan bulbil. hasil penelitian menunjukkan bahwa sterilisasi umbi dan bulbil yang paling optimal adalah perendaman menggunakan fungisida 3 g/l + bakterisida 3 g/l (12 jam), kemudian clorox 30% (15 menit) ditambah perlakuan didalam LAF berupa perendaman alkohol 70% (1 menit), asam askorbat 100 mg/l (1 jam), alcohol 70% (5-10 detik), clorox 1% (10 menit), betadine 10% (10 menit), dan betadine 15 tetes (10 menit) berturut-turut, dengan eksplan yang digunakan berupa bulbil dengan dilakukan teknik pengupasan kulit dan pemotongan menjadi bagian yang lebih kecil sebelum perlakuan sterilisasi didalam LAF. Ditunjukkan hasil eksplan yang bertahan hingga ± 90 HST tanpa adanya kontaminasi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
