Judul: Karakterisasi fisiko kimia minyak goreng pada proses penggorengan berulang dan umur simpan kacang salut yang dihasilkan
Abstrak: Minyak goreng merupakan salah satu komponen penting dalam proses pengolahan pangan, khususnya dalam proses menggoreng bahan pangan, yaitu dengan fungsi utama sebagai media penghantar panas. Selama penggorengan, minyak dipanaskan pada periode yang panjang dengan suhu tinggi dan berada pada kondisi terdapat udara dan air. Hal ini menyebabkan terjadinya reakksi kimia yang kompleks seperti reaksi hidrolisis, oksidasi, dan polimerisasi. Terdapat hubungan yang erat antara kualitas minyak goreng yang digunakan dengan produk yang dihasilkan. Penurunan kualitas minyak goreng yang digunakan berdampak pada menurunnya kualitas produk yang dihasilkan. Adanya penurunan kualitas minyak goreng ini menyebabkan umur simpan produk berbeda antara satu proses penggorengan dengan proses penggorengan sebelumnya. Oleh karena itu, karakteristik minyak goreng erlu diketahui sebelum digunakan untuk menghasilkan produk dengan shelf life yang di inginkan sehingga perlu dicari uji kualitas minyak goreng yang dapat menggambarkan kualitas minyak goreng secara tepat.

Judul: Hubungan Kualitas Minyak Goreng yang Digunakan secara Berulang terhadap Umur Simpan Keripik Sosis Ayam
Abstrak: Minyak atau lemak pada industri makanan ringan (snack food) mempunyai fungsi utama sebagai media transfer panas. Selama proses penggorengan, minyak mengalami degradasi karena pengaruh panas, udara dan kadar air yang menyebabkan penurunan kualitas minyak goreng. Penurunan kualitas minyak akan mempengaruhi kualitas produk yang dihasilkan, karena minyak yang terserap dapat melebihi 45% bobot produk (Saguy dan Pinthus, 1995). Penelitian ini bertujuan untuk mendapatkan informasi tentang hubungan antara kualitas minyak yang dipakai secara berulang terhadap umur simpan keripik sosis dan kelayakan industri keripik sosis. Penelitian dibagi menjadi empat tahap. Tahap pertama adalah penentuan waktu penggorengan vakum untuk menghasilkan keripik sosis dengan kadar air yang minimal. Tahap kedua adalah proses penggorengan keripik sosis sampai 30 kali penggorengan dengan menggunakan minyak goreng yang sama (tidak diganti). Tahap ketiga adalah penentuan umur simpan keripik sosis yang dihasilkan pada masing-masing frekuensi penggorengan (ke-1, ke-15 dan ke-30), sedangkan tahap keempat adalah perhitungan analisa kelayakan pendirian industri keripik sosis ayam.

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
