Diet on Egg Quality of Quail (Coturnix coturnix japonica).
Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas pemberian ransum yang disuplementasi vitamin D3 terhadap kualitas fisik telur puyuh. Percobaan dilakukan pada ternak puyuh yang berusia 22 minggu dan dipelihara sampai umur 27 minggu dengan jumlah 450 ekor. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 3 perlakuan dan 5 ulangan yaitu P0: Ransum tanpa suplementasi vitamin D3 (ransum kontrol), P1: P0 suplementasi vitamin D3 1,0 g kg-1, P2: P0 suplementasi vitamin D3 1,5 g kg-1. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan bila berbeda nyata. Hasil penelitian menunjukkan bahwa penambahan vitamin D3 dalam pakan sangat nyata (P, This study aimed to determine the effectiveness of feeding diets supplemented with vitamin D3 on the physical quality of quail eggs. The experiment was carried out using quail aged from 22 weeks and reared until the age of 27 weeks with a total of 450 quails. The research method used a completely randomized design (CRD) consisting of 3 treatments and 5 replications, namely P0: diet without vitamin D3, P1: P0 vitamin D3 1.0 g kg-1, P2: P0 vitamin D3 1.5 g kg-1. Data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan’s test if they were significantly different. The result showed that the addition of vitamin D

Judul: Evaluation of Vitamin D3 Supplementation in Diet on Quail (Coturnix coturnix japonica) Production Performance
Abstrak: Penurunan performa produksi pada puyuh akan berdampak secara ekonomis pada peternak. Rekayasa nutrisi pakan menggunakan vitamin D3 merupakan salah satu solusi yang dapat dilakukan untuk mengatasi masalah tersebut. Penelitian ini bertujuan mengevaluasi suplementasi vitamin D3 dalam ransum terhadap performa produksi puyuh. Ternak sebanyak 450 ekor dipelihara dari umur 22-27 minggu. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 5 ulangan, setiap ulangan menggunakan 30 ekor puyuh. Perlakuan terdiri atas P0 = ransum kontrol, P1 = ransum kontrol + vitamin D3 1,0 g kg-1 ransum, dan P2 = ransum kontrol + vitamin D3 1,5 g kg-1 ransum. Peubah yang diamati yaitu konsumsi pakan, quail day production (QDP), bobot telur, produksi massa telur, efisiensi pakan, mortalitas, dan income over feed cost (IOFC). Data dianalisis dengan sidik ragam (ANOVA) dan uji lanjut Duncan menggunakan SPSS 25 untuk hasil yang berpengaruh nyata. Hasil penelitian menunjukkan suplementasi vitamin D3 dengan dosis 1,5 g kg-1 ransum berpengaruh nyata (P<0,05) meningkatkan QDP, produksi massa telur, dan efisiensi pakan. Dapat disimpulkan bahwa vitamin D3 pada dosis 1,5 g kg-1 ransum dapat meningkatkan performa produksi puyuh., A decrease in laying quail performance will have an economic impact to the farmers. Modification in feed nutrition using vitamin D3 is one of the solution that can be done to overcome this problem. This study aimed to evaluate the supplementation of vitamin D3 in diet on quail production performance. A total of 450 quails were kept from age 22-27 weeks. This study used a Completely Randomized Design (CRD) with 3 treatments and 5 replications, each replication used 30 quails. The treatment diets consisted of P0 = control diet, P1 = control diet + vitamin D3 1.0 g kg-1 diet, and P2 = control diet + vitamin D3 1.5 g kg-1 diet. The variables observed were feed consumption, quail day production (QDP), egg weight, egg mass, feed efficiency, mortality and income over feed cost (IOFC). Data were analyzed using ANOVA and treatment that differed significantly were further tested with Duncan’s Test using SPSS 25 software. The results showed that the supplementation of vitamin D3 with dose 1.5 g kg-1 diet significantly (P<0.05) increased QDP, egg mass, and feed efficiency. It can be concluded that vitamin D3 at dose 1.5 g kg-1 diet can increase the quail production performance.

Judul: Sistem Pengklasifikasian Entitas pada Pesan Twitter Menggunakan Ekspresi Regular dan Naïve Bayes
Abstrak: The widespread use of social networks like Twitter encourages some institutions to find out the entities that are discussed and the sentiment toward the entities. This research aims to build a system that can extract entities in tweets and classify the sentiment from the tweets. Entity extraction process is done using regular expressions. Writing regular expressions can capture the diverse entities. Sentiment classification is performed using naïve Bayes classification with Multinomial and Bernoulli models. Sentiment in this research consists of three classes, namely positive, negative, and neutral. Before entering the classification, tweets are normalized by replacing the non-standard words with the standard ones. The test results show that regular expression is quite effective for the entity extraction process. As for the results of the classification, naïve Bayes method produces high accuracy (96.75% for Multinomial and 96.33% for Bernoulli). However, the accuracy obtained depends on the neutral class which amounts to 97.88% for Multinomial and 99.95% for Bernoulli, while the positive class are 85.66% and 33.13% and negative class are 33.67% and 0%.
