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 Feed on the Physical Quality of Eggs from Lohmann Layer Hens Aged 91-94 Weeks
Abstrak: Penelitian ini bertujuan untuk mengevaluasi efek suplementasi Vitamin D3-500 dalam pakan terhadap kualitas fisik telur dalam upaya mempertahankan kualitas telur ayam petelur Lohmann di umur tua. Penelitian ini menggunakan 108 ekor ayam petelur dengan strain Lohmann Brown umur 91 minggu hingga umur 94 minggu dan rataan bobot badan 1801-1840 g ekor-1. Penelitian ini menggunakan Rancangan Acak Lengkap yang terdiri atas 3 perlakuan dan 4 ulangan serta tiap ulangan menggunakan 9 ekor. P0=Pakan kontrol (tanpa suplementasi Vitamin D3), P1=Pakan kontrol + suplementasi Vitamin D3 1,0 g kg-1, P2=Pakan kontrol + suplementasi Vitamin D3 1,5 g kg-1. Peubah yang diukur meliputi bobot telur, tebal kerabang, warna kuning telur, indeks telur, haugh unit, persentase bobot telur, konsumsi kalsium, dan konsumsi fosfor. Data dianalisis menggunakan ANOVA. Hasil penelitian menunjukkan suplementasi Vitamin D3-500 tidak berpengaruh nyata terhadap bobot telur, tebal kerabang, warna kuning telur, indeks telur, haugh unit, persentase bobot telur, namun kualitas fisik telur masih termasuk dalam standar yang baik. Kesimpulan peneletian ini adalah suplementasi Vitamin D3 sampai dosis 1,5 g kg-1 pakan tidak berpengaruh terhadap kualitas fisik telur, karena kandungan Ca da P dalam ransum serta konsumsinya sudah mencukupi kebutuhan ayam Lohmann umur 91-94 minggu., This study aimed to evaluate the effects of Vitamin D3-500 supplementation in feed on the physical quality of eggs, focusing on maintaining the quality of older Lohmann Brown laying hens. The study involved 108 hens aged 91 to 94 weeks with an average body weight of 1801-1840 g each. It utilized a Completely Randomized Design with 3 treatments and 4 replications, each consisting of 9 hens. The treatments were: P0 = Control diet (no Vitamin D3 supplementation), P1 = Control diet + Vitamin D3 supplementation at 1.0 g kg-1, P2 = Control diet + Vitamin D3 supplementation at 1.5 g kg-1. Variables measured included egg weight, shell thickness, yolk color, egg index, haugh unit, egg weight percentage, calcium consumption, and phosphorus consumption. Data were analyzed using ANOVA. Results indicated that Vitamin D3-500 supplementation did not significantly affect egg weight, shell thickness, yolk color, egg index, Haugh unit, or egg weight percentage. Despite this, the physical quality of the eggs remained within acceptable standards. The conclusion of this study is that supplementing Vitamin D3 up to 1.5 g kg-1 in the diet did not influence egg quality, as the dietary calcium and phosphorus content met the requirements for Lohmann hens aged 91-94 weeks.

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%.
