Judul: Nilai Gizi Daging Squab Burung Merpati Lokal dan Homer pada Jenis Kelamin yang Berbeda
Abstrak: Daging merupakan salah satu komoditi asal ternak yang penting sebagai sumber protein hewani bagi manusia. Daging squab (piyik) burung merpati mempunyai kekhasan yang berbeda dibandingkan dengan daging unggas yang lainnya. Daging burung merpati memiliki warna daging yang merah, serat daging yang halus, kandungan kolesterol yang rendah dan mempunyai kandungan protein yang cukup tinggi. Produksi daging squab burung merpati di Indonesia belum banyak seperti daging unggas lain, sehingga harga daging squab burung merpati cukup mahal. Masyarakat belum banyak mengetahui informasi mengenai nilai gizi dari daging squab burung merpati, sehingga konsumen daging squab jumlahnya terbatas. Penelitian ini bertujuan untuk mengetahui nilai gizi (kadar air, kadar protein, kadar lemak dan kolesterol) daging squab burung merpati Lokal dan Homer baik jantan maupun betina. Selain itu memperoleh informasi tambahan mengenai berat hidup akhir squab, berat dan persentase karkas squab termasuk kepala, leher dan kaki, berat dan persentase karkas squab.

Judul: Sifat fisik dan organoleptik daging squab burung merpati homer dan burung merpati lokal pada jenis kelamin yang berbeda
Abstrak: This research was conducted to study the physical caracteristic and organoleptic of Homer and Local pigeon squab meat in different sex. The results of the experiment showed that there was no irteraction in strain and sex on all variables. The slaughter weight of the Homer pigeon squab was 376.41e44.368 higher than Local pigzon squab was 330.96f40.27g. The slaughter weight male pigeon squab was 385.88e39.69g higher than female pigeon squab was 321.50rt28.76. The carcass percentage of Homer pigeon squab was 56.99+4.40% lower than Local pigeon squab was 62.23+7.99'%. The carcass percentage male and female pigeon squab between 56.33+5.09% and 66.91*7.03%.

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.
