Judul: Residu Antibiotika pada Susu di Malaysia : Sebuah Tinjauan
Abstrak: Antibiotic residue in milk products is a major public health concern as it can pose a risk to human health and contribute to antibiotic resistance. Milk from cows treated with antibiotics may contain residues of the drugs, which can persist through the milk production process and end up in the final milk products. The consumption of these products can lead to adverse health effects, including allergic reactions and the development of antibiotic-resistant bacteria in humans. There are regulatory frameworks in place in many countries, including the establishment of Maximum Residue Limits (MRLs) for antibiotics in milk, withdrawal periods for antibiotics, testing and surveillance programs to detect and prevent antibiotic residues in milk products. However, challenges remain in enforcing these regulations and ensuring compliance among dairy farmers and milk processors. There is also a need for further research to better understand the long-term health effects of consuming milk products with antibiotic residues, as well as the development of new methods for detecting and monitoring antibiotic residues in milk. Overall, the prevention and control of antibiotic residue in milk products is essential for protecting public health and combating the spread of antibiotic resistance.

Abstrak: Antimicrobial drugs have been used in dairy industry for more than five decades. Dairy herd health is closely associated with milk production and economic sustainability. Therefore, maintenance of herd health is closely dependent upon disease prevention and therapeutic drug use for a range of diseases. The presence of antibiotic residues in milk is a public health issue. The purpose of the present study ware to know the relationships of farmer characteristics and antibiotic residues presence in raw milk, wich used as cheese production. Farmer characteristics (age, education, breeding time, training, and number of lactating cows) were used to find the relationship between the farmer’s knowledge and the presence of antibiotic residues in raw milk. The yoghurt tests method was used to figure out the existence of antibiotic residues in raw milk as the basic material for making cheese. Eighteen raw milk samples were taken from three farmer groups that supply the milk to the cheese factory in Sukabumi. Yoghurt test showed that the milk from group A did not contain antibiotic residues, while the milk from group B and C contained antibiotic residues. Farmer characteristics indicating significant correlation with antibiotic residues presence were farmer’s education and number of lactating cows.

Abstrak: Kapal SV Vivian merupakan kapal pariwisata yang terbuat dari kayu solid. Kapal SV Vivian terdiri dari bagian lunas, linggi haluan dan linggi buritan, gading-gading, wrang, galar kim, galar balok, balok geladak dan lutut-lutut, kulit luar, geladak, pagar, sekat kedap air. Pembuatan kapal hanya didasarkan pada pengalaman, sehingga perlu diteliti untuk mengetahui karakteristik komponen kayu yang digunakan. Penelitian mengukur karakteristik atau sifat-sifat dasar komponen kayu yang digunakan pada bagian gading-gading, linggi dan lunas. Standar pengujian yang digunakan yaitu BS-373: 1957. Jenis kayu yang digunakan untuk pembuatan lunas dan linggi yaitu kayu Ulin (Eusideroxylon zwageri) dan gading-gading menggunkan kayu kempas (Koompasia malacensis). Kayu ulin memiliki karakteristik yang lebih baik dibandingkan dengan kayu kempas. Kayu ulin masuk kedalam kelas kuat I dan tahan terhadap serangan marine borers sehingga tergolong kedalam kelas awet I. Kempas tergolong kedalam kayu dengan kelas kuat II dan ketahanan terhadap marine borers masuk kedalam kelas awet V. Bagian lunas kapal disambung dengan menggunakan baut dan jenis sambungan yang digunakan yaitu plain scarf.
