Judul: The Effect of Partnership on Production and Income of Sugarcane Farmers in Malang Regency
Abstrak: Krebet Baru Sugar Factory has entered into a partnership with sugar cane farmers in Malang Regency. Partnerships have a role in technical services and a separate sugarcane purchasing process which causes differences in the production and income of sugarcane farmers. Therefore, this research aims to analyze the effect of partnerships on the production and income of sugar cane farmers in Malang Regency. Respondents in this study were 70 sugar cane farmers consisting of 45 partner sugar cane farmers and 25 non-partner sugar cane farmers with a sampling method, namely random sampling for partner farmers and snowball sampling method for non-partner farmers. The analytical methods used are Income Analysis and Multiple Linear Regression Analysis. The research results show that partnerships do not have a significant effect on the production and income of sugar cane farmers in Malang Regency. However, farmers who enter into partnerships have higher average values for sugarcane production per hectare and income per hectare than farmers who do not enter into partnerships., Pabrik Gula Krebet Baru telah melakukan kemitraan dengan petani tebu di Kabupaten Malang. Kemitraan memiliki peran pada pelayanan teknis dan proses pembelian tebu tersendiri yang menyebabkan perbedaan pada produksi dan pendapatan petani tebu. Oleh karena itu, penelitian ini bertujuan untuk menganalisis pengaruh kemitraan terhadap produksi dan pendapatan petani tebu di Kabupaten Malang. Responden dalam penelitian ini berjumlah 70 petani tebu yang terdiri dari 45 petani tebu mitra dan 25 petani tebu non-mitra dengan metode penentuan sampel yaitu random sampling untuk petani mitra dan metode snowball sampling untuk petani non-mitra. Metode analisis yang digunakan yaitu Analisis Pendapatan dan Analisis Regresi Linier Berganda. Hasil penelitian menunjukkan bahwa kemitraan tidak berpengaruh secara signifikan terhadap produksi dan pendapatan petani tebu di Kabupaten Malang. Selain itu, petani yang melakukan kemitraan memiliki nilai rata-rata yang lebih tinggi pada produksi tebu per hektare dan pendapatan per hektare dibandingkan petani yang tidak melakukan kemitraan.

Judul: Asymptotic Distribution of Estimator for the Intensity Function of a Doubly Periodic Poisson Process
Abstrak: In this manuscript, estimation of the intensity function of a doubly periodic Poisson process is discussed. It is assumed that only a single realization of the Poisson process is observed in a bounded window [0,n]. It is also assumed that the period of the intensity function is known. The rate of consistency and asymptotic normality of the estimator are formulated. Finally, a confidence interval for the local intensity function is also formulated.
