Pengaruh Penambahan Level Gula Merah pada Air Minum terhadap Konsumsi Pakan, Konsumsi Air, dan Pertambahan Bobot Badan Itik Pedaging Fase Starter
Authors: Winata Adi , Dahlan Mufid , Fadlilah Anik 
Published: January 2022

Itik peking merupakan satu dari temak unggas penghasil daging yang sangat berpotensi selain ayam. Gula merah merupakan sumber tambahan energi cepat tersedia bagi itik karna mudah diserap. Penambahan gula merah dalam air minum pada itik akan memperbaiki pertumbuhan maupun daya hidup, dan bertujuan memperbaiki konsumsi pakan, konsumsi air serta pertambahan bobot badan. Materi pada penelitian yakni day old duck (DOD) Peking pedaging berjumlah 80 ekor yang berjenis kelamin tidak dibedakan (Unsex). Metode pada penelitian yakni Rancangan Acak Lengkap (RAL) pola searah dengan 4 perlakuan serta 4 ulangan. Penambahan level gula merah pada air minum itik diberikan secara berturut-turut yakni P0 = (ransum basal + air minum dengan pemberian gula merah 0%), P1 = (ransum basal + air minum dengan pemberian gula merah 5%), P2 = (ransum basal + air minum dengan pemberian gula merah 10%) dan P3 = (ransum basal + air minum dengan pemberian gula merah 15%) pada itik berumur 0 hari sampai 14 hari. Hasil analisis ragam (ANOVA) memperlihatkan bahwa penambahan level gula merah pada air minum memiliki pengaruh nyata (P<0,05) terhadap konsumsi pakan serta pertambahan bobot badan, namun penambahan level gula merah pada air minum tidak berpengaruh nyata (P>0,05) terhadap konsumsi air. Hasil penelitian menunjukkan bahwa nilai rerata konsumsi pakan pada P0 (33,632 gr/ekor/hari), P1 (37,666 gr/ekor/hari), P2 (32,201 gr/ekor/hari) dan P3 (28,938 gr/ekor/hari). Nilai rataan konsumsi air pada P0 (209,393 ml/ekor/hari), P1 (194,955 ml/ekor/hari), P2 (192,670 ml/ekor/hari) dan P3 (196,607 ml/ekor/hari). Nilai rataan pertambahan bobot badan pada P0 (19,905 gr/ekor/hari), P1 (19,658 gr/ekor/hari), P2 (17,256 gr/ekor/hari) dan P3 (16,708 gr/ekor/hari). Berdasarkan uji DUNCAN kesimpulan pada penelitian ini bahwa perlakuan yang memberikan nilai terbaik terhadap konsumsi pakan dan pertambahan bobot badan adalah P1 yaitu dengan memberikan 5% gula merah dalam air minum itik.

Tujuan penelitian untuk mengetahui pengaruh umur terhadap pola pertumbuhan kambing Boerka jantan di UPT. Agri Science Technopark Universitas Islam Lamongan. Materi yang dipakai yakni kambing boerka jantan berjumlah 17 ekor (3 ekor kambing prasapih, 9 ekor lepas sapih, dan 5 ekor kambing dewasa). Variabel yang diamati meliputi berat badan, lingkar dada, tinggi pundak, serta panjang badan. Data yang didapat ditabulasi dan dianalisis secara kuantitatif dengan analisis regresi polynomial. Hasil penelitian menunjukkan bahwa pola pertumbuhan kambing boerka jantan mengikuti kurva sigmoid (S) dengan persamaan regresi polinomial berganda berturut-turut, yaitu : bobot badan y = 0,003x3 - 0,1226x2 + 2,748x + 2,1532; lingkar dada y = -0,1095x² + 3,8853x + 39,898; tinggi pundak y = -0,0358x² + 2,1436x + 41,699; dan panjang badan y = -0,0431x2 + 2,1206x + 43,398. Dengan nilai koefisien determinasi berturut-turut : bobot badan 98,47%, lingkar dada 89,25%, tinggi pundak 92,32%, dan panjang badan 59,88%. Pola pertumbuhan bobot badan serta ukuran tubuh lainnya pada kambing Boerka jantan di UPT. Agri Science Techopark UNISLA mengalami pertumbuhan yang terus meningkat mulai dari umur 0-18 bulan. Hal ini terjadi karena ternak belum mencapai usia tua. Apabila umur ternak semakin tinggi maka bobot badan maupun ukuran tubuh lainnya juga akan bertambah. Nilai koefisien determinasi paling tinggi pada bobot badan 98,47% dan terendah pada panjang badan 59,88%. Perihal ini menunjukkan bahwa adanya pengaruh umur terhadap pola pertumbuhan kambing Boerka jantan di UPT. Agri Science Techopark UNISLA.

Published: January 2022

Bimbingan Belajar (Bimbel) adalah suatu bentuk bantuan untuk peserta didik agar mampu melakukan penyesuaian diri, membuat beberapa pilihan, memecahkan masalah-masalah pendidikan, pengajaran dan pembelajaran yang sedang dihadapinya. Untuk siswa yang ingin melakukan pembelajaran di bimbel, orang tua harus memenuhi pembayaran perbulannya. Maka munculah permasalahan dibimbel khususnya pada pembayaran, yaitu pendataan masih menggunakan manual yaitu tulis tangan di dalam buku besar, banyak orangtua siswa yang mengajukan pembayaran dengan menyicil sehingga pihak bimbel kesulitan menentukan siapa yang layak mendapat cicilan dan bimbel memberikan cicilan tanpa melihat kemampuan orang tua dan ekonomi yang mengakibatkan pemberian cicilan ke orang tua siswa tidak sesuai targetnya dan pembuatan laporan juga memerlukan banyak waktu karena harus mengecek buku besar dan rekapan. Sehingga tujuan dari penelitian ini adalah membuat sebuah sistem komputer yaitu untuk meringankan pekerjaan admin dalam pendataan admin, pendataan siswa, pendataan wali siswa, pendataan permohonan cicilan, menghitung proses penentuan kelayakan cicilan agar mendapat hasil yang lebih akurat dan pembuatan laporan dari prosesnya agar dapat menjadi lebih cepat dan tepat dimana metode pengambilan keputusan menggunakan SAW dan dirancang menggunakan flowchart. Sehingga didapatkan solusi untuk permasalahan di bimbel bintang cemerlang yaitu dengan membuat perhitungan kelayakan penerima cicilan dengan hasil yang akurat.

OBJECTIVE
Magnetic resonance imaging (MRI) is the gold-standard tool for diagnosing lumbar spinal stenosis (LSS), but it is difficult to promptly examine all suspected cases with MRI considering the modality’s high cost and limited accessibility. Although radiography is an efficient screening technique owing to its low cost, rapid operability, and wide availability, its diagnostic accuracy is relatively poor. In this study, the authors aimed to develop a deep learning model with a convolutional neural network (CNN) for diagnosing severe central LSS using radiography and to evaluate radiological diagnostic features using gradient-weighted class activation mapping (Grad-CAM).

METHODS
Patients who had undergone both spinal MRI and radiography in the period from May 1, 2005, to December 31, 2017, were screened. According to the formal MRI report, participants were consecutively included in the severe central LSS or healthy control group, and radiographs for both groups were collected. A CNN-based transfer learning algorithm was developed to classify radiographic findings as LSS or normal (binary classification). The proposed models were evaluated using six performance metrics: area under the receiver operating characteristic curve (AUROC), accuracy, sensitivity, specificity, and positive and negative predictive values.

RESULTS
The VGG19 model achieved the highest accuracy with an AUROC of 90.0% (95% CI 89.8%–90.3%) by training 12,442 images. Accuracy was 82.8% (95% CI 82.5%–83.1%) by averaging 5-fold models. Feature points on Grad-CAM were reasonable, and the features could be categorized into reduced disc height, narrow foramina, short pedicle, and hyperdense facet joint. The AUROC in the extra validation was 89.3% (95% CI 88.7%–90.0%). Accuracy was 81.8% (95% CI 80.6%–83.0%) by averaging 5-fold models. Multivariate logistic regression analysis showed that a combination of demographic factors (age and sex) did not improve the model performance.

CONCLUSIONS
The algorithm trained by a CNN to identify central LSS on radiographs showed high diagnostic accuracy and is expected to be useful as a triage tool. The algorithm could accurately localize the stenotic lesion to assist physicians in the identification of LSS.
