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: Analysis of Rice Farming Income and Technical Efficiency (Case Study of Warungkondang Sub-District, Cianjur Regency and Cibungbulang, Bogor Regency)
Abstrak: Kecamatan Warungkondang dan Cibungbulang memiliki potensi lahan yang luas untuk ditanami padi, namun produksi padi rendah. Peningkatan produksi padi menjadi hal yang sangat penting mengingat pertumbuhan penduduk meningkat setiap tahun sehingga kebutuhan terhadap padi sebagai sumber pangan meningkat. Jumlah produksi yang lebih banyak akan meningkatkan pendapatan petani. Produksi padi yang tinggi belum tentu menunjukkan proses produksi yang efisien. Penelitian ini memiliki tujuan untuk: (1) menganalisis pedapatan usahatani padi, (2) mengidentifikasi faktor-faktor yang memengaruhi produksi padi, dan (3) menganalisis efisiensi teknis usahatani padi di Kecamatan Warungkodang dan Cibungbulang. Pendapatan usahatani padi akan dianalisis menggunakan analisis penndapatan dan R/C Ratio. Faktor-faktor yang memengaruhi produksi padi akan dianalisis dengan analisis linear berganda. Efisiensi teknis usahatani padi akan dianaisis menggunakan Stochastic Frontier Analysis. Hasil penelitian menunjukkan bahwa R/C ratio petani Kecamatan Warungkondang dengan luas lahan sempit dan luas adalah 1,20 dan 1,30 dan petani padi Kecamatan Cibungbulang yang memiliki lahan sempit dan luas memiliki nilai R/C ratio adalah 1,10 dan 1,12. Pada kedua kecamatan faktor-faktor yang memengaruhi usahatani adalah jumlah benih dan tenaga kerja. Kecamatan Warungkondang dan Cibungbulang memiliki nilai efisiensi teknis sebesar 0,86 dan 0,65. Faktor inefisiensi Kecamatan Warungkondang adalah pendidikan petani dan pada Kecamatan Cibungbulang adalah pedidikan dan tanggungan keluarga., Warungkondang and Cibungbulang Sub-District have potentially spacious land to be planted by rice, however their rice production are low. Increasing rice production become important considering there’s increasing population every year. Efficient rice farmers will produce more rice than others who don’t efficient. That is why the purposes of this study are: (1) to analyze income of rice farming, (2) to identify the factors that influence the production of rice, (3) to analyze the technical efficiency of rice farming in Warungkondang and Cibungbulang Sub-District. The method for income analysis is R/C ratio. The factors that influence rice production will be analyzied with Ordinary Least Square. Technical efficiency will be analyzed with Stochastic Frontier Analysis. The results of this study showed that rice farmers of Warungkondang Sub-District with narrow land and wide land R/C ratio are 1,20 and 1,30 and rice farmers of Cibungbulang Sub-District with land narrow wide R/C ratio are 1,10 and 1,12. The factors that influence rice production in both SubDistrict are seed and labor. Warungkondang and Cibungbulang Sub-District efficiency values are 0,86 and 0,65. Factors that influence technical inefficiency in Warungkondang Sub-District are farmers’ education and for Cibungbulang SubDistrict are farmers’ education and family members.

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.
