Judul: Youth’s Perceptions of Organic Agriculture and  Its Influence on Entrepreneurial Interests.
Abstrak: Salah satu masalah nyata yang terjadi di sektor pertanian adalah jumlah petani yang terus menurun. Minat generasi muda untuk menjadi petani atau pelaku usaha di bidang pertanian juga cenderung menurun. Generasi muda berpersepsi bahwa bekerja di sektor pertanian lebih melelahkan dibanding dengan non-pertanian, dikarenakan dalam bidang pertanian para petani bekerja di luar ruangan. Penelitian ini bertujuan untuk mengidentifikasi persepsi generasi muda tentang pertanian organik dan untuk mengetahui pengaruhnya terhadap minat berwirausaha dengan melakukan survey kepada 63 anggota Komunitas Petani Muda Indonesia. Metode pengumpulan sampel menggunakan probability sampling, dengan metode analisis data menggunakan analisis deskriptif dan SEM-PLS. Hasil dalam penelitian ini menunjukan bahwa generasi muda memiliki pengetahuan dan pandangan yang positif tentang pertanian organik yang berpengaruh terhadap minat berwirausaha, tetapi minat mereka terhadap pertanian organik cenderung rendah, hal ini disebabkan oleh beberapa faktor, seperti pemasaran produk organik yang sulit, banyaknya masyarakat yang belum paham tentang produk organik dan harga produk organik yang disamakan dengan produk pertanian konvensional oleh masyarakat. Kesimpulannya persepsi berpengaruh terhadap minat generasi muda untuk berwirausaha pertanian organik, One of the real problems that occur in the agricultural sector in Indonesia is the number of farmers that continues to decline. The interest of the younger generation to become a farmer or entrepreneur in agriculture also tends to decline. They perceive that working in the agricultural sector is more tiring than non-agriculture, because in agriculture farmers work outdoors. This study aims to identify the perception of the younger generation about organic farming and to find out its effect on entrepreneurial by conducting a survey to 63 members of Komunitas Petani Muda Indonesia. The sample collection method uses probability sampling, using descriptive analysis and SEM-PLS. The results in this study show that the younger generation has a positive knowledge of organic farming that affect entrepreneurial, but their interest to organic farming tends to be low, this is due to several factors, such as the marketing of organic products that are difficult, many people who don’t understand about organic products and the price of orgnic products that are equated with conventional agricultural products by the community. The conclution is perception affects the interest of young generation to become an entrepreneur.

Judul: Farmer's and Farmer's Children's Perception of Interest in Working in the Agricultural Sector
Abstrak: Petani merupakan aktor penting dalam keberlanjutan pangan dan pertanian. Namun terjadi penuaan petani dan penurunan minat generasi muda terhadap pertanian. Demi keberlanjutan sektor pertanian, regenerasi petani ini menjadi isu penting yang dibahas perlu untuk segera direalisasikan. Penurunan minat petani disebabkan oleh berbagai faktor yaitu faktor internal dan eksternal. Penelitian ini bertujuan untuk menganalisis bagaimana persepsi anak petani terhadap minat kerja di sektor pertanian. Metode yang digunakan yaitu metode kuantitatif dengan instrumen kuesioner dan didukung dengan data kualitatif menggunakan wawancara mendalam serta observasi. Metode ini dipilih untuk melihat pengaruh faktor internal dan eksternal terhadap persepsi dan memperkuat analisis tersebut menggunakan data kualitatif. Anak petani melihat sektor pertanian dan petani sebagai pekerjaan yang kurang menjanjikan dari segi pendapatan, tetapi sangat membantu untuk memenuhi kebutuhan primer. Anak petani tidak memiliki kemauan untuk bekerja di sektor pertanian namun merasa hal tersebut adalah keharusan untuk bertahan hidup. Karakteristik individu dan faktor eksternal tidak berpengaruh signifikan terhadap persepi anak petani, Farmers are essential actors in the sustainability of food and agriculture. However, there is an aging of farmers and a decline in the interest of the younger generation in agriculture. For the sake of the sustainability of the agricultural sector, farmer regeneration is an important issue that needs to be discussed and realized immediately. The decline in farmer interest is caused by various factors, namely internal and external factors. This study analyzes how farmer children perceive interest in working in the agricultural sector. The method used is quantitative, with a questionnaire as an instrument, and is supported by qualitative data using in-depth interviews and observation. This method was chosen to see the influence of internal and external factors on perceptions and to strengthen the analysis using qualitative data. Farmers' children see the agricultural and farming sectors as less promising jobs in terms of income but are very helpful in meeting primary needs. Farmers' children do not have the will to work in the agricultural sector but feel it is a must for survival. Individual characteristics and external factors have no significant effect on the perceptions of farmer children

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
