Judul: Analysis Competitiveness of Rice Business in Rainfed Lowland and Irrigated Rice Field Business In Klaten
Abstrak: BIMOSENO SEPFRIAN. Analysis Competitiveness of Rice Business in Rainfed Lowland and Irrigated Rice Field Business In Klaten. Supervised by ANDRIYONO KILAT ADHI dan MUHAMMAD FIRDAUS. One of the strategic agricultural development programs is food self-sufficiency. This self-sufficiency is called rice self-sufficiency because rice is the main food ingredient in food self-sufficiency. Rice is a strategic food crop to creat self-sufficiency rice in Indonesia. The purpose of this study was to analyze competitiveness based on competitive, comparative, and sensitivity advantages in rainfed and irrigated rice fields in Klaten district. The method used in determining the sample was done by purposive sampling. Data analysis used the Policy Analysis Matrix (PAM) method and sensitivity analysis. The results showed that the rainfed lowland and irrigated rice fields in Klaten Regency had competitive and comparative advantages. Private profits from rainfed lowland rice farming and irrigation are IDR 2,825,597.13 and IDR 9,482,818.4, respectively. The social benefits of rainfed lowland rice farming and irrigation are IDR 13,208,071 and IDR 28,096,366, respectively. The PCR value of Irrigated Rice is 0.56 and the rainfed is 0.80. The DRC value in irrigated lowland rice was 0.30, lower than the DRC value in rainfed lowland rice, which was 0.50. The sensitivity analysis saw that when there was a 20% decrease in output in rainfed rice, it was no longer competitive because the PCR value became 1.01 from 0.80 while irrigated rice fields remained competitive with a PCR value of 0.71 from the previous 0 , 56. For rainfed lowland rice farming, it is necessary to have additional technology to increase production during a longer dry season or lower rain intensity so that production does not decrease due to water shortages in rainfed rice fields which make it unable to compete competitively and comparatively.

Judul: Analisis Pendapatan Usahatani dan Faktor-Faktor yang Mempengaruhi Produksi Padi Hibrida dan Inbrida (Studi Kasus Desa Suru, Kecamatan Doko, Kabupaten Blitar, dan Desa Clumprit, Kecamatan Pagelaran, Kabupaten Malang, Jawa Timur)
Abstrak: Food is a one of based necessary that must be completed by human. One of food that being a main necessary for Indonesia people is rice. In a row of total society improvement, necessary of rice will grow every years. Rice demand in Indonesia can not be completed all by a rice production in Indonesia. This problem make a goverment take a policy by making rice import in short term and innovation utilize of hybrid seeds for improving a rice production in long term. Blitar and Malang district were areas which have a wide land of hybrid rice at East Java. Suru Village - Doko sub district and Clumprit village - Pagelaran sub district were have hybrid rice land. First purpose of this research was to analyze the characteristic of hybrid and non-hybrid rice for agricultural business which use by farmers at Suru Village and Clumprit Village with descriptive analysis. Second purpose of this research was to analyze income rate of farmers which use hybrid and non-hybrid rice at Suru Village and Clumprit Village by using π = TR-TCdan R/C ratio method. Based on this research the farmers of hybrid rice get a higher income rather than farmers of non-hybrid rice. The business of hybrid and non-hybrid rice agriculture were suitable to do because R/C ratio of agricultural business based on total cost and cash cost were higher than one. Third purpose of this research was to know about factors that influenced hybrid and non-hybrid of rice production at Suru Village and Clumprit Village by using a linear regression. Based on result, factors that influenced rice production were seeds, organic fertilizer, solid pesticide, labour, and production difference between hybrid rice and non-hybrid rice.

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
