Judul: Karakter Fisikokimia dan Kadar Pati Resisten Tapioka Hasil Modifikasi Heat Moisture Treatment (HMT) Menggunakan Oven
Abstrak: Tapioka dimodifikasi dengan heat-moisture treatment (HMT) pada suhu 120ºC dan 140ºC selama 16 dan 24 jam dengan kadar air 20% . Selama HMT, terjadi penurunan kadar air sekitar 73,38 - 85,95 %, sehingga kadar air HMT aktual hanya 3 - 4 % . Proses HMT menyebabkan hilangnya sifat birefringence di tengah beberapa granula tapioka, penurunan kristalinitas (kecuali untuk HMT tapioka 120-24) tetapi tidak mengubah tipe kristalin dari tapioka. Kandungan amilosa, kapasitas pembengkakan dan kelarutan tapioka HMT lebih rendah dari tapioka alami. HMT tapioka memiliki kadar RDS dan SDS yang secara signifikan lebih tinggi dari bentuk alaminya (kecuali tapioka HMT 120-24) sedangkan kadar RS tidak berbeda nyata . HMT menyebabkan perubahan karakteristik pasta pati . Viskositas puncak, suhu pasting dan viskositas breakdown relatif pasta dari tapioka HMT secara signifikan lebih rendah dibandingkan tapioka alami. Secara umum, perubahan dari semua parameter sangat dipengaruhi oleh kondisi proses .

Judul: Pengaruh Heat Moisture Treatment terhadap Sifat tekstural dan Retrogradasi Gel Pati Aren dan Tapioka
Abstrak: Heat Moisture Treatment (HMT) is one of physical modification techniques that uses limited moisture where heating process at high temperature is implemented for certain period of time. This research studied the effect of HMT modification on textural properties and retrogradation of aren and tapioca starch gel. HMT modification was done by using autoclaving method at 120 oC in 60 minutes for tapioca and 90 minutes for aren. Before autoclaving process, the water content of starch was adjusted into 20% (b/b, wb). The observation of retrogradation was done on starch gel with water content 10% (b/b, db) and refrigerated at 4 oC for 7 days. Textural analysis was done by doing compression using texture analyzer. Degree of retrogradation analysis was done by analyzing the changes of hardness from starch gel, and analyzing amylose hydrolisis using α-amylase enzyme. The result from textural analysis and degree of retrogradation analysis show that HMT modification could make starch gel become fragile, shown by decreasing breaking strain. From degree of retrogradation analysis, it is known that HMT modification increased hardness and degree of retrogradation of starch gel. According to this research, it can be concluded that HMT modification could make starch gel become fragile, increase hardness, and increase retrogradation of native starch gel.

Judul: Zoonosis yang baru muncul bersumber satwa liar dan tantangan kesehatan masyarakat veteriner
Abstrak: The objective of this scientific writing was to review the emerging infectious diseases (EIDs) which are zoonotic and originate in wildlife causing great negative impacts on public health, economy, social, politic, and national security. Furthermore, factors triggering the emergence and spread of emerging zoonotic diseases and global efforts in anticipating them were discussed in this review. It is recognized that EID are a significant burden on global economies and public health. Their emergence is thought to be driven largely by socio-economic, environmental and ecological factors. EID events are dominated by zoonoses (60.3% of EIDs) and the majority of these (71.8%) originate in wildlife, e.g., severe acute respiratory virus (SARS virus) and Ebola virus. The importance and recognition of wildlife as a reservoir of zoonoses are increasing. Emerging zoonoses (EZs) have been assumed increasing importance in public and animal health. Cost effective prevention and control of these zoonoses need an interdisciplinary and holistic approach and international cooperation. Surveillance, laboratory capability, research, training and education, and communication are key elements. Globalization has created many new challenges, particularly with regard to animal, human, and environmental health. New approaches in prevention, control, and eradication of zoonotic diseases have been developed and introduced worldwide, i.e., one health and ecohealth. The one health concept is a worldwide strategy for expanding interdisciplinary collaboration and communications in all aspects of health care for humans and animals, while ecohealth approach is to improve human health and well-being while simultaneously maintaining a healthy ecosystem.
