Judul: Internal Organs Profile of IPB-D1 Chickens Fed Diet Containing Jack Bean Meal (Canavalia ensiformis L.) and Lactic Acid Bacteria in Drinking Water
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian tepung koro pedang (Canavalia ensiformis L.) dalam ransum dan bakteri asam laktat dalam air minum terhadap profil organ dalam ayam IPB-D1. Penelitian ini menggunakan rancangan acak lengkap faktorial (2x2). Faktor (1) tepung koro pedang (0%, 20% dalam ransum) dan (2) bakteri asam laktat (0, 107 CFU/ml). Peubah yang diamati adalah jantung, hati, ginjal, timus, bursa Fabricius, limpa, pankreas, empedu, proventrikulus, gizzard, duodenum, jejunum, ileum, sekum dan kolon. Tepung koro pedang nyata (p, This experiment was aimed to evaluation effect of providing jack bean meal (Canavalia ensiformis L.) in diet and lactic acid bacteria in drinking water on the internal organs profile of IPB-D1 chickens. This study used a factorial completely randomized design (2x2). Factors (1) jack bean meal (0%, 20% in diet) and (2) lactic acid bacteria (0, 107 CFU/ml). The variables observed were heart, liver, kidneys, thymus, bursa of Fabricius, spleen, pancreas, gallbladder, proventriculus, gizzard, duodenum, jejunum, ileum, cecum and colon.

Judul: The Use of Jack Bean (Canavalia ensiformis L.) in Feed and its Effect on Carcass Percentage, Non-Carcass Percentage, and Immune Organs in Broiler Chickens
Abstrak: Tujuan penelitian ini adalah menganalisis pengaruh pemberian ransum dengan kacang koro pedang terhadap persentase bobot karkas, non karkas, dan organ imunitas. Penelitian ini menggunakan ayam broiler betina CP dengan total 250 ekor. Ayam dibagi menjadi 4 perlakuan yang terdiri 6 kali ulangan, yaitu P0: Pakan komersial, P1: Pakan kontrol, P2 : Pakan dengan penggunaan 5% kacang koro pedang, P3 : Pakan dengan penggunaan 10% kacang koro pedang. Parameter yang diukur adalah persentase karkas, persentase non karkas, dan organ imunitas ayam broiler. Data dianalisis dengan analysis of variance (ANOVA), jika hasil berpengaruh nyata, maka dilanjutkan dengan uji Duncan. Hasil analisis ragam menunjukkan penambahan kacang koro pedang dalam substisusi bungkil kedelai dalam pakan tidak berpengaruh nyata (P>0,05) terhadap persentase karkas, kepala, kaki, organ imunitas, bursa fabrisius, timus, dan limpa ayam broiler. Disimpulkan bahwa pemberian pakan 10% kacang koro pedang olahan dapat mensubtitusi penggunaan bungkil kedelai dalam pakan ayam broiler dan memberikan hasil yang baik pada persentase karkas, kepala, kaki, bursa fabrisius, timus, dan limpa., This research aimed to analyze the effect of feeding a feed with jack bean on the percentage of carcass weight, non-carcass weight, and immune organs in broiler chickens. The study used 250 female CP 707 broiler chickens. There were 4 treatments with 6 replications: P0 - Commercial feed, P1 - Control feed, P2 - feed with 5% processed jack bean meal, and P3 - feed with 10% processed jack bean meal. The measured parameters included carcass percentage, non-carcass percentage, and broiler chicken immune organs. The data were analyzed using analysis of variance (ANOVA), and if the analysis results were statistically significant, Duncan's test was conducted. The analysis of variance showed that the addition of jack bean in soybean meal substitution did not have a significant effect (P>0.05) on the carcass percentage, head percentage of broiler chickens, leg percentage, immune organ weight percentage, bursa of fabrisius weight percentage, thymus weight percentage, and average lymph weight percentage. However, feeding with 10 processed jack bean yielded favorable results.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
