Judul: Morphometric Relationship of FH Dairy Cow Body Digital Image with Milk Production in Cijeruk District Bogor
Abstrak: Produktivitas susu sapi perah disebabkan oleh beberapa faktor. Ukuran linear tubuh sapi perah menjadi salah satu faktor yang berpengaruh terhadap produktivitas susu. Tujuan penelitian adalah menganalisis hubungan morfometrik tubuh sapi perah Friesian Holstein secara citra digital dengan produksi susu di peternakan rakyat sapi perah Desa Tajurhalang, Kecamatan Cijeruk, Kabupaten Bogor, Jawa Barat. Bagian tubuh yang diukur adalah panjang badan, tinggi pinggul, dalam dada, dan lingkar dada. Pengukuran morfometrik dilakukan dengan mengambil foto tubuh sapi FH menggunakan kamera DSLR kemudian diolah menggunakan perangkat lunak ImageJ. Data diolah menggunakan perangkat lunak Minitab 18 dengan mencari persamaan regresi dan koefisien korelasi terhadap produksi susu. Hasil penelitian menunjukkan koefisien determinasi terkoreksi antara panjang badan, tinggi pinggul, dalam dada, dan lingkar dada dengan produksi susu rendah. Dalam dada dan lingkar dada memiliki hubungan yang rendah namun dapat berpengaruh terhadap produksi susu. Penelitian ini sangat efisien untuk mengukur tubuh sapi dalam jumlah yang banyak., Dairy cow milk productivity is caused by several factors. The linear size of the body of dairy cow is one of the factors that affect milk productivity. This research aims to analyze the morphometric relationship between the body of Friesian Holstein cow using digital images and milk production in the dairy farm Tajurhalang Village, Cijeruk District, Bogor Regency, West Java. The body part measured were body length, hip height, chest depth, and chest circumference. The morphometric measurements were carried out by taking a photo of the FH cow body using a DSLR camera and then processing with ImageJ software. The data was processed using Minitab 18 software by looking for the regression equation and the correlation coefficient on milk production. The results showed that the adjusted Rsquared between body length, hip height, chest depth, and chest circumference with milk production is low. Chest depth and chest circumference has a low relationship but can affect milk production. This research very efficient to measure the body of cows in large number.

Judul: Implementation of Digital Image as a Method of  Morphometric Relationship of Dairy Cow FH Body with Milk Production in  KUNAK Bogor
Abstrak: Kawasan Usaha Peternakan (KUNAK) merupakan kawasan peternakan sapi perah yang terletak di Kecamatan Cibungbulang dan Kecamatan Pamijahan Kabupaten Bogor. Tujuan penelitian adalah menganalisis hubungan morfometrik tubuh panjang badan, tinggi badan, dalam dada dan lingkar dada sapi perah Friesian Holstein terhadap produksi susu di Kawasan Usaha Peternakan sapi perah Kabupaten Bogor menggunakan metode citra digital. Pengukuran dilakukan menggunakan Software Image J kemudian ditabulasi ke dalam Microsoft Excel. Data diolah menggunakan Minitab 19 dengan mencari persamaan regresi linear terbaik kemudian dibandingkan dengan koefisien korelasi antara panjang badan, tinggi badan, dalam dada dan lingkar dada dengan produksi susu. Hasil penelitian menunjukan bahwa persamaan regresi linear terbaik diperoleh dari panjang badan, dalam dada dan lingkar dada yang dikategorikan sangat kuat. Nilai korelasi antara panjang badan, dalam dada dan lingkar dada dengan produksi susu adalah 0,857, 0,823 dan 0,850. Parameter ukuran tubuh panjang badan, dalam dada dan lingkar dada merupakan parameter ukuran tubuh yang dapat mempengaruhi produksi susu.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
