Judul: Kajian Pustaka Sifat Mekanik Bioplastik Pati Umbi Gadung sebagai Film Edibel Terkomposit Sabut Kelapa
Abstrak: Film edibel merupakan bioplastik yang digunakan sebagai kemasan produk yang dapat dikonsumsi bersama produk tersebut. Bahan utama dalam pembuatannya adalah pati. Berdasarkan penelitian sebelumnya, sumber pati yang digunakan ini merupakan bahan pangan yang banyak dikonsumsi oleh masyarakat. Oleh karenanya, karya ilmiah ini mengkaji sumber pati dari umbi gadung yang belum dimanfaatkan secara maksimal oleh masyarakat sebagai bahan pangan. Tujuan dari kajian ini ialah membuat pati dari umbi gadung dan selulosa dari sabut kelapa serta mengkaji sifat mekanik bioplastik pati-selulosa sebagai film edibel melalui kajian pustaka. Untuk memperoleh film edibel yang baik, pati ditambahkan gliserol sebagai pemlastis dan selulosa sabut kelapa sebagai penguat. Berdasarkan kajian pustaka, penambahan selulosa dari sabut kelapa pada bioplastik berbasis pati dapat meningkatkan nilai kuat tarik dan ketahanan terhadap airnya, tetapi menurunkan elastisitasnya.

Judul: Potensi Bioplastik Berbasis Pati Kulit Singkong dengan Pengisi Selulosa Sabut Kelapa berdasarkan Studi Literatur
Abstrak: Bioplastik merupakan jenis plastik yang mampu didegradasi oleh mikroorganisme. Tujuan penelitian ini adalah memperoleh pati kulit singkong dan selulosa sabut kelapa sebagai bahan baku bioplastik. Kulit singkong dipilih sebagai bahan baku karena memiliki kandungan pati yang tinggi. Rendemen pati kulit singkong segar yang dihasilkan pada penelitian ini mendekati 25%. Pengisi berupa selulosa sabut kelapa digunakan untuk memperbaiki sifat mekanik bioplastik dengan rendemen mendekati 15%. Penelitian ini dilanjutkan dengan studi literatur untuk mengevaluasi sifat mekanik bioplastik berbasis pati dengan pengisi selulosa. Hasilnya mengungkapkan bahwa kuat tarik bioplastik komposit pati-selulosa cenderung lebih tinggi dibandingkan tanpa selulosa. Pemanjangan bioplastik tersebut cenderung lebih rendah sedangkan hidrofobisitas cenderung lebih tinggi dibandingkan dengan bioplastik tanpa selulosa. Studi ini juga mengungkapkan bahwa interaksi yang terjadi antara pati dan selulosa merupakan interaksi fisik yang ditandai dengan tidak terciptanya gugus fungsi baru pada spektrum inframerah.

Judul: Dog Ticks Infestation and Its Correlation to Tick-Borne Diseases.
Abstrak: Ticks infestation on dog could lead to itchiness, anemia, skin disorders, and tick-borne diseases, such as Ehrlichiosis, Babesiosis, Anaplasmosis and Rocky Mountain Spotted Fever. Besides dogs, Ehrlichiosis were known to be zoonotic. Pre-mature stage tick life cycle that occur outside its host, will enhance contacts between ticks and human. The study of ticks infestation and tick-borne diseases on the dog is necessary, because it has not a lot of information about the diversity, prevalence and degree of ticks infestation in Indonesia. Ticks survey, included ticks sampling and dogs blood test were performed at Animal Police Directorate Security Agency (Baharkam) and Atang Sendjaja Air Force (ATS). Meanwhile ticks sampling also data of cases of ticks infestation and diseases transmitted obtained from 21 veterinary clinics in Bogor, Jakarta and Bandung. All ticks samples stored in bottles containing 70% alcohol for identification. Blood tests performed for Ehrlichiosis, Babesiosis and Anaplasmosis diagnosis. The identification results of the 950 ticks samples that obtained from 97 dogs of Baharkam, ATS and veterinary clinics in Bogor, Jakarta and Bandung, showed only one ticks species, Rhipicephalus sanguineus. This ticks belong to three-host tick, which require three hosts to complete its life cycle. Each ticks stage need a host, either same dog (if it is in place there is only one or a few dogs), as well as different dogs. Research in Baharkam conducted on 81 dogs (53 males and 28 females). The prevalence of dogs infested by ticks was 67.90%. The percentage of male dogs that infested by ticks are larger (69.81%) than female (64.29%). Based on Chi-Square test, there was no relationship between sex and breed of dog with degree of ticks infestation. Generally dogs infested with mild infestation category (41.98%), meanwhile moderate category was 18.52%, 2.47% high and 4.94% very high. The dog’s body region that the most infested by R. sanguineus was dog's back. Probably these body regions were be preferred because they are less accessible for the dog to remove them with its paws. Collection of ticks with tick-drag on Baharkam grass field showed positive results on the field that was more often used to practice by dogs. The samples that obtained was larvae stage ticks with density 152 larvae on 215m2 area of the field. Adult stage ticks and several adult females which laying eggs on the cage wall were obtained in the dog kennels. Whole of male and female ATS dogs infested with ticks (14 dogs). In general, dogs infested with very high infestation category was 64.29%, compared by high degree category (21.43%) and moderate (14.29%). Ticks predilection were found mostly on the dog’s head – neck. On ATS grass field did not reveal any ticks, but positively inside the kennels. It happens probably because dogs are rarely released from the kennel, so that the ticks was did drop-off inside the kennel. The total cases of ticks infestation of dogs at Bogor, Jakarta and Bandung veterinary clinics in 2008 until June 2013 as many as 731 cases. In general, there was an increases of the ticks infestation prevalence at three cities in that range
