Judul: Performance of Broiler Chicken which Feeded Ration Containing Energy Source for Corn Substitute
Abstrak: Penelitian ini bertujuan untuk mengevaluasi bahan pakan lokal sorgum, gaplek, dan sagu utuh sebagai pengganti jagung dalam ransum terhadap performa ayam broiler. Peubah yang diamati adalah bobot badan akhir, pertambahan bobot badan, konsumsi pakan, konversi pakan, dan mortalitas selama pemeliharaan pada umur 7-35 hari. Rancangan percobaan yang dilakukan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan yaitu ransum komersial (P0), ransum berbasis sorgum (P1), ransum berbasis gaplek (P2) dan ransum berbasis sagu parut kering (P3). Setiap perlakuan terdiri atas 3 ulangan dengan kepadatan 16-17 ekor m-2 pada tiap ulangan dengan jumlah ayam sebanyak 200 ekor. Hasil penelitian menunjukkan bahwa rata-rata bobot badan akhir, pertambahan bobot badan, dan konversi pakan berbeda sangat nyata (P<0,01) lebih rendah dibandingkan perlakuan kontrol, sedangkan konsumsi pakan tidak berbeda nyata. Performa ayam broiler pada perlakuan P1, P2, dan P3 tidak berbeda nyata. Pemberian ransum berbasis sorgum, gaplek, dan sagu parut kering sebagai substitusi jagung ransum pada ayam broiler menghasilkan performa yang lebih rendah dibandingkan pakan komersial., This study aimed to evaluate local feed ingredients such as sorghum, cassava, and whole sago as an energy source to replace on the performance of broiler chickens. The variables observed included body weight, body weight gain, feed consumption, feed conversion ratio and mortality from 7 to 35 days of age. The experimental design carried out was a completely randomized design (CRD) with 4 treatments, namely commercial ration (P0), complete ration based on sorghum (P1), complete ration based on cassava (P2), complete ration based on dry grated sago (P3). Each treatment consisted of 3 replications with a density of 16-17 m-2 in each repetition with total of 200 chickens. The results showed that the average final body weight, body weight gain, and feed conversion ratio were very significantly different (P<0.01) lower than the control treatment, while feed consumption was not significantly different. The performance of broiler chickens in treatment P1, P2, and P3 was not significantly different. The diet contain sorghum, cassava, and dry grated sago as a substitute corn in broiler chicken rations resulted in lower body weight gain compared with the commercial feed.

Judul: Performance of KUB chicken that were given a zea mays subtitution as energy source of native chicken ration
Abstrak: Penelitian ini bertujuan menguji bahan pakan lokal sumber energi yang diperkaya sehingga memiliki komposisi nutrisi yang setara dengan jagung dalam ransum ayam kampung. Penelitian ini menggunakan 200 ekor DOC ayam KUB yang diberi pakan 4 perlakuan ransum yang memiliki sumber energi yang berbeda. Keempat Perlakuan tersebut terdiri dari: P0(ransum berbasis jagung), P1 (ransum berbasis gaplek), P2(ransum berbasis sorghum), dan P3(ransum berbasis batang pohon sagu). rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL) 4perlakuan dan 3 ulangan dengan masing masing ulangan terdiri dari 15 ekor. Peubah yang diamati meliputi konsumsi ransum, bobot badan, pertambahan bobot badan, konversi pakan dan mortalitas ayam. Data yang diperoleh dianalisis menggunakan anova dan uji jarak DUNCAN. Hasil penelitian menunjukkan bahwa pengaruh perlakuan subtitusi jagung berbasis gaplek, sorghum dan batang pohon sagu yang diperkaya dalam ransum ayam kampung tidak berpengaruh nyata (P<0,05) dibandingkan dengan ransum kontrol berbasis jagung terhadap performans ayam kampung umur satu sampai delapan minggu., This study aimed to test local feed ingredients as energy sources which were enriched so that they have a nutritional composition equivalent to corn for native chicken chicken rations. This study used 200 DOC native chickens which were fed with 4 ration treatments which had different energy sources. The four treatments consisted of: P0 (corn-based ration), P1 (cassava-based ration), P2 (sorghum-based ration), and P3 (sago stem-based ration). The research design used was a completely randomized design (CRD) with 4 treatments and 3 replications, each replication consisted of 15 chickens. The observed variables included feed consumption, final body weight, body weight gain, feed conversion and mortality. The data obtained were analyzed using ANOVA and the DUNCAN distance test. The results showed that the effect of treatment on cassava, sorghum and sago of the diet based on did not had any significant effect (P<0.05) compared to the diet based corn on the performance of native chickens aged 1-8 weeks.

Judul: Asymptotic Distribution of Estimator for the Intensity Function of a Doubly Periodic Poisson Process
Abstrak: In this manuscript, estimation of the intensity function of a doubly periodic Poisson process is discussed. It is assumed that only a single realization of the Poisson process is observed in a bounded window [0,n]. It is also assumed that the period of the intensity function is known. The rate of consistency and asymptotic normality of the estimator are formulated. Finally, a confidence interval for the local intensity function is also formulated.
