Judul: Performa Ayam Broiler Yang Diberi Air Minum Dengan Penambahan Kunyit (Curcuma domestica Vahl.)
Abstrak: Kunyit merupakan salah satu tanaman obat yang dapat dijadikan sebagai feed additive pada ayam broiler. Penelitian ini bertujuan untuk mengevaluasi air minum yang ditambahkan kunyit terhadap performa ayam broiler. Ayam yang digunakan yaitu strain Ross sebanyak 200 ekor. Penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri dari 4 taraf perlakuan (K0 = kontrol, K1 = air minum + kunyit 8 g L-1, K2 = air minum + kunyit 16 g L-1, dan K3 = air minum + kunyit 24 g L-1) dengan 5 kali ulangan. Peubah yang diamati yaitu konsumsi pakan, konsumsi air minum, bobot badan, pertambahan bobot badan, konsumsi kurkumin, konversi pakan, mortalitas, indeks performa, dan Income Over Feed and Chick Cost (IOFCC). Data yang diperoleh dianalisis ragam (ANOVA) yaitu konsumsi pakan, konsumsi air minum, bobot badan, pertambahan bobot badan, konsumsi kurkumin, dan konversi pakan, dilanjutkan dengan uji Tukey dan uji Polinomial Orthogonal. Hasil penelitian menunjukkan bahwa penambahan kunyit pada air minum berpengaruh sangat nyata (P<0.01) terhadap konsumsi air minum dan konsumsi kurkumin, berbeda nyata (P<0.05) terhadap konsumsi pakan, bobot badan, pertambahan bobot badan, dan konversi pakan. Penambahan kunyit dalam air minum dapat menurunkan angka mortalitas, menaikan indeks performa, dan nilai IOFCC

Judul: Effect of Adding Turmeric Flour (Curcuma Domestica Val) as Feed Additive on Broiler Chicken Performance
Abstrak: Penggunaan feed additive dalam ransum menjadi alternatif efisiensi pakan pada ayam broiler. Kunyit (Curcuma domestica) merupakan tanaman herbal yang memiliki kandungan zat aktif berupa kurkumin sebagai antioksidan dan minyak atsiri sebagai pemusnah bakteri serta mengandung sifat antiinflamasi atau antiradang, sehingga berpotensi untuk dijadikan feed additive alami. Penelitian ini bertujuan mengkaji efek penambahan tepung kunyit pada pakan sebagai feed additive terhadap performa ayam broiler dengan metode studi pustaka dan pendekatan model matematis regresi linear sederhana. Terdapat 17 studi terindeks scopus, garuda dan sinta (science technology index) yang dipublikasikan tahun 2006-2020 ditabulasi pada Microsoft Excel. Parameter studi pustaka yang digunakan yaitu meliputi bobot akhir (g ekor-1), konsumsi pakan (g ekor-1 hari-1), PBB (g ekor-1 hari-1), FCR, mortalitas (%) dan hemoglobin (g dL-1). Data yang telah ditabulasi, dianalisis menggunakan IBM SPSS versi 20. Hasil analisis menunjukkan bahwa penambahan tepung kunyit pada pakan secara signifikan (P<0,01) berpengaruh terhadap peningkatan pertambahan bobot badan dan bobot badan akhir. Penambahan tepung kunyit tidak berpengaruh (P>0,10) terhadap konsumsi pakan, Feed Conversion Ratio, angka mortalitas ayam broiler, dan hemoglobin. Berdasarkan hasil penelitian, penambahan tepung kunyit dengan level 0,50% merupakan dosis paling optimal yang dapat meningkatkan pertambahan bobot badan dan bobot akhir ayam., The use of feed additives in the ration is an alternative to feed efficiency in broiler chickens. Turmeric (Curcuma domestica) is an herbal plant that contains active substances in the form of curcumin as an antioxidant and essential oil as a bacteria destroyer and contains anti-inflammatory or anti-inflammatory properties, so it has the potential to be used as a natural feed additive. This study aims to examine the effect of adding turmeric flour to feed as a feed additive on the performance of broiler chickens using a literature review method and a simple linear regression mathematical model approach. There are 17 scopus, garuda and sinta indexed studies (science technology index) published in 2006-2020 tabulated in Microsoft Excel. The literature study parameters used included final weight (g head-1), feed consumption (g head-1day-1), PBB (g head-1 day-1), FCR, mortality (%), and hemoglobin (g dL-1). The tabulated data were analyzed using IBM SPSS version 20. The results of the analysis showed that the addition of turmeric flour to the feed significantly (P<0,01) had an effect on increasing body weight gain and final body weight. The addition of turmeric flour had no effect (P>0,10) on feed consumption, Feed Conversion Ratio, broiler mortality rate, and hemoglobin. Based on the results of the study, the addition of turmeric flour with a level of 0,50% is the most optimal dose that can increase body weight gain and final weight of chickens.

Judul: Pengembangan Bagian Offline pada Shapefile Encryption System (SES)
Abstrak: Geographical Information System (GIS) data are classified as expensive and sensitive data. The biggest threat to be dealed by GIS data at the moment is the spread of illegally accessed and distributed by unauthorized party. Currently, most of protection methods that are applied on GIS data focused on the use of digital watermarking. But, this method does not restrict GIS data from being accessed and distributed illegally. This research intends to develop a protection system for GIS data in shapefile form by combining Advanced Encryption Standard (AES) algorithm, Rivest Shamir Adleman (RSA) algorithm, and image steganography technique Least Significant Bit (LSB) which can provide confidentiality and authentication service. As a result, a standalone application is built using the security life cycle development method. The application is being tested on five different shapefile data to measure the effect from four different RSA key lengths towards the execution times needed to perform encryption and decryption process.
