Judul: Evaluasi Aspek Teknis dan Strategi Pengembangan Sapi Perah Rakyat di Kabupaten Karo Sumatera Utara
Abstrak: Animal husbandry of dairy cattle is one effort in the field of a farm that has strategic role in meet the needs of food. The development of dairy cattle encourages the creation of animal husbandry is sustained. One of the areas animal husbandry of dairy cattle the people in North Sumatera are Karo District which until now are still experiencing stagnation. The Central Bureau of Statistics Karo year 2014 noted the population of dairy cattle years 2009-2011 down by 35.46%. In the 2012-2013 back increased by 29.07% of the population of 2011 but in general the data the last five years showed that the decrease in the population as much as 16.70%. A trend of decreasing is greatly affected by the condition of management and environment. Farm productivity of dairy cattle the people low was also affected the environment of the internal and external research so that aims for the evaluation of the technical aspects of animal husbandry and animal husbandry development strategy of dairy cattle the people according to the principle of good dairy farming practices (GDFP). The method used is the survey. The sample collection farmers use the survey respondents with a total of sampling as many as 18 peoples. The use of expert respondents research aimed to obtain relevant information in the preparation of the strategy the development of dairy cattle the people. The determination of purposively sampling done as many as 4 peoples. Data processing using chi-square test the results of research . The preparation of strategies carried out by classifying two enviroment factors which is external factors and internal analysis and training. The result showed the value of GDFP highest on the management aspects of as much as 3.05 (good category) and the lowest is at the health aspect of livestock 1.52 (category less good). The total score weights the internal environment factor of 2.502 the score and the total weight of the external environment factor 2.525. The position of internal external matrix be on a cell 5 shows the development of animal husbandry of dairy cattle the people who fit in karo district use strategy growth through horizontal integration.

Judul: Evaluasi Good Dairy Farming Practices pada Peternakan Rakyat di Karangploso dan Jabung Kabupaten Malang Jawa Timur
Abstrak: Dairy farm is one of the livestock sub sector that can help sustain the development of national economy and contribution to fill the nutritional needs of the community. The production to meet the needs of the national milk was still not optimal. So need to increase productivity through genetic improvement, environment, population increase and management of maintenance. The study was conducted by survey method at Karangploso and Jabung, Malang, in May to June 2013. The purpose of the research is to study the technical aspects of dairy cattle raising. The materials were used as many as 34 farmers at Karangploso and 38 farmers at Jabung who have <20 dairy cows, with using multistage stratified random sampling technique and descriptive analysis. The results showed the average of the study on the application of Good Dairy Farming Practices (GDFP), the maintenance aspect of dairy at Karangploso was applying 2.81 or included in the category of enough, whereas the application of the maintenance aspects at Jabung at 3.05 which is included in good categories. Jabung which has contributed in providing information related to continue aspects of dairy farming. Based on the results of the review can be concluded that the GDFP at Karangploso’s members need improvement for better maintenance management than Jabung’s members.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
