Judul: The Addition of Antioxidants to The Ratiom Contains PUFA Against Nulliparous Hematology and Blood Metabolites in The Folliculogenesis Phase
Abstrak: Penelitian bertujuan untuk mengevaluasi gambaran darah calon induk kambing betina pada fase folikulogenesis dengan pemberian ransum mengandung PUFA dan penambahan antioksidan. Penelitian menggunakan 10 ekor kambing Boerja betina yang dibagi menjadi 2 perlakuan dan 5 kelompok. Perlakuan terdiri dari A0= ransum mengandung PUFA tanpa antioksidan dan A1= ransum mengandung PUFA dengan penambahan antioksidan 200 ppm asal ekstrak daun nangka. Peubah yang diamati pada penelitian yaitu konsumsi bahan kering, protein kasar, lemak kasar, karbohidrat, TDN, hematologi, dan metabolit darah. Data yang diperoleh dianalisis menggunakan software SPSS dengan t-test independent. Simpulan dari penelitian adalah kombinasi pemberian ransum mengandung PUFA dengan penambahan 200 ppm antioksidan asal ekstrak daun nangka menunjukkan hematologi dan metabolit darah yang lebih baik yang dapat dilihat dari meningkatnya kadar PCV, eosinofil, basofil, dan kadar trigliserida dibandingkan kambing Boerja betina yang tidak diberi penambahan antioksidan pada fase folikulogenesis., This study aimed to evaluate the blood picture of nulliparous in the folliculogenesis phase by giving rations containing PUFA and the addition of antioxidant. This study used 10 nulliparous Boerja divided into 2 treatments and 5 replicates. The treatment consisted of A0= ration containing PUFA without antioxidants and A1= ration containing PUFA with the addition of 200 ppm antioxidant from jackfruit leaves extract. The variables observed included dry matter intake, crude protein, crude fat, carbohydrate, TDN, hematology, and blood metabolites. The data obtained were analyzed using SPSS software with an independent t-test. The conclusion of this study is that the combination of PUFA containing rations with the addition of 200 ppm antioxidant from jackfruit leaves extract showed better hematology and blood metabolites which can be seen from increased levels of PCV, eosinophils, basophils, and triglyceride levels compared nulliparous Boerja that were not given the addition of antioxidants in the folliculogenesis phase.

Judul: Hematology and Blood Metabolites of Boerja Goats in Premating Phase with Rations Containing Protected PUFA
Abstrak: Pemberian PUFA menjadi salah satu upaya untuk mengoptimalkan potensi prolifik pada kambing Boerja fase dara. PUFA yang dinilai dapat memberikan dampak positif terhadap proses reproduksi adalah omega-3 dan omega-6. Penggunaan PUFA tersebut rentan mengalami biohidrogenasi dalam rumen, sehingga diperlukan proteksi dalam bentuk sabun kalsium. Penelitian ini bertujuan mengevaluasi hematologi dan metabolit darah kambing Boerja fase dara yang diberi ransum mengandung PUFA terproteksi. Rancangan percobaan yang digunakan adalah rancangan acak kelompok dengan 2 perlakuan dan 5 kelompok. Perlakuan terdiri dari P0 yang merupakan ransum mengandung PUFA tanpa proteksi, dan P1 merupakan ransum mengandung PUFA terproteksi. Peubah yang diukur adalah konsumsi zat makanan, hematologi, dan metabolit darah. Hasil penelitian menunjukkan bahwa perlakuan PUFA terproteksi tidak menghasilkan perbedaan nyata (P>0,05) pada konsumsi zat makanan, hematokrit, hemoglobin, BDM, BDP, limfosit, neutrofil, eosinofil, monosit fase luteal, basofil fase luteal, kadar glukosa, trigliserida, dan albumin. Perlakuan PUFA terproteksi memberikan pengaruh yang berbeda nyata (P<0,05) pada persentase monosit dan basofil pada fase folikuler, serta kadar kolesterol. Kata kunci: hematologi, kambing, metabolit, PUFA terproteksi, Providing PUFA can be an effort to optimize the prolific potential of heiferstage Boerja goats. PUFAs that are considered have positive impact on reproductive system are omega-3 and omega-6. The use of PUFA is susceptible to biohydrogenation in rumen, so protection in calcium soap form is needed. This research aimed to evaluate hematology and blood metabolites of heifer-stage Boerja goat fed a rations containing protected PUFA. The experimental design used was randomized block design with 2 treatment and 5 groups. The treatment consisted of P0 (ration containing PUFA without protection), and P1 (ration containing protected PUFA). The observed variable were nutrient consumption, hematology, and blood metabolites. The result showed that treatment of protected PUFA had no different significant (P>0,05) on nutrient consumption, hematocrit, hemoglobin, erythrocyte, leukocyte, lymphocytes, neutrophils, luteal phase monocytes, luteal phase basophils, glucose levels, triglycerides, and albumin. Treatment of protected PUFA had different significant (P>0,05) on percentage of monocytes and basophils in follicular phase, as well as cholesterol levels.

Judul: Formulasi TSP (Traveling Salesman Problem) menggunakan ILP (Integer Linear Programming)
Abstrak: TSP is a journey of salesman f?om his origin town (place) to visit n-cities (places) only at once, then return to his origin town (place) with a minimum total distance. Its purpose is to minimize the operating expense that is released by the company. Vehicle route at TSP in the form of a Hamiltonian cycle, that is closed path containing all nodes at the graph which representing a network walk. Its problem is to determine a journey route which is feasible (possibly can be passed by) in such a way the vehicle travelled distance passed the route is minimum.
