The purpose of this study is to analyze the influence of entrepreneurial orientation on the entrepreneurial resilience of vegetable farms in Lembang. This study used primary data obtained from questionnaires from interviews conducted with vegetable farmers. Then, the data acquisition was analyzed using PLS-SEM analysis. The results of the analysis show that an entrepreneurial orientation with an innovative attitude can increase the entrepreneurial resilience of vegetable farms in Lembang. The results of the analysis also show that proactive attitude and risk-taking in entrepreneurial orientation cannot increase the entrepreneurial resilience of vegetable farms in Lembang. Vegetable farmers who have an increasingly large land area and entrepreneurial competencies (the ability to build networks, the ability to identify opportunities, and the ability to realize opportunities) have a positive influence on the entrepreneurial resilience of vegetable farms.

Judul: The Influence of Entrepreneurial Characteristics on the Business Success of Beef Cattle Farmers in Blora Regency
Abstrak: Kabupaten Blora terkenal sebagai sentra sapi potong di Jawa Tengah dan tidak pernah mengalami penurunan produksi dalam sepuluh tahun terakhir. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik kewirausahaan terhadap keberhasilan usaha. Pengumpulan data dilakukan dengan wawancara dan pengisian kuesioner dengan menggunakan dua teknik sampling, yaitu cluster sampling dan purposive sampling. Jumlah sampel pada penelitian ini sebanyak 100 responden dan data dianalisis dengan Structural Equational Modeling Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa masing-masing variabel karakteristik kewirausahaan yang terdiri dari percaya diri, bekerja keras, berorientasi masa depan, inovatif, berani mengambil risiko, dan tanggung jawab tergolong baik. Variabel keberhasilan usaha mampu dijelaskan 87,6 persen oleh masing-masing variabel karateristik kewirausahaan dengan nilai R-square sebesar 0,876. Karakteristik kewirausahaan yang berpengaruh signifikan terhadap keberhasilan usaha diantaranya bekerja keras, berorientasi masa depan, inovatif, dan tanggung jawab. Sedangkan percaya diri dan berani mengambil risiko berpengaruh tidak signifikan terhadap keberhasilan usaha., Blora Regency is known as a center for beef cattle in Central Java and has never experienced a decline in production in the last ten years. This research aims to analize the influence of entrepreneurial; characteristics on business success. Data collection was carried out by interviews and filling out questionnaires using two sampling, namely cluster sampling and purposive sampling. The number of samples in this research was 100 respondens and the data was analyzed using Structural Equational Modeling Partial Least Square (SEM-PLS). The result of the research show that each variable of entrepreneurial characteristic consisting of self-confidence, working hard, future-oriented, innovative, daring to take risks, and responsibility is classified as good. The business success variable can be explained 87,6 percent by each entrepreneurial characteristic variable with an R-square value 0,876.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
