Judul: Pengembangan pasar produk nugget jamur tiram (Pleorotus ostreotus) dengan pendekatan riset aksi
Abstrak: Perubahan pola konsumsi masyarakat saat ini yang mengarah pada makanan siap saji membuat pangan olahan beku semakin diminati. Namun bahan baku yang tidak bermutu dan bahan tambahan pangan berbahaya pada produk membuat konsumen menjadi ragu dalam mengonsumsinya. Tujuan dari penelitian ini adalah mengidentifikasi permasalahan yang terjadi pada konsumen makanan olahan beku serta menyajikan solusi untuk permasalahan tersebut sehingga diperoleh model bisnis terbaik. Penelitian dilakukan dengan pendekatan riset aksi dengan tahapan pengembangan pasar yang terdiri atas perancangan hipotesis kanvas model bisnis, pengujian permasalahan, perancangan profil produk, pengujian solusi, dan verifikasi kanvas model bisnis. Hasil penelitian menunjukkan bahwa terdapat permasalahan responden yaitu kandungan bahan tambahan pangan berbahaya pada produk olahan beku, bahan baku yang bermutu rendah, kandungan gizi produk yang kurang, dan harga pangan olahan beku yang bermutu tinggi terlalu mahal. Berdasarkan penelitian diperoleh hasil bahwa nugget jamur tiram dapat menjadi solusi terhadap permasalahan tersebut. Segmen yang dituju adalah orang tua yang memiliki anak usia balita diatas satu tahun hingga sekolah dasar, membutuhkan variasi makanan sehat dan bergizi serta kepraktisan dalam penyajian makanan bagi anak. Saluran penjualan yang diminati adalah toko jual beli melalui internet, penjual khusus dan distributor…

Judul: Pengembangan Pasar Produk Masakan Sayur Terolah Minimal dengan Pendekatan Riset Aksi
Abstrak: Indonesian’s vegetable consumption level is relatively low. It is caused by consumption behaviors, nature of vegetables, and vegetable process. The purposes of the research are to identify problems of vegetables consumption, to find a customer segment, to provide solutions, to identify the product positioning and sales channel roadmap, and to generate a business model. This research used action research through customer development which consisted business model hypotheses, problem testing, solution testing, verification, sales channel roadmaping, and product positioning. The results showed that problems were the freshness of vegetables, the availability of time, process, nutrition, and hygiene. Customer segment who had these problems were professional women from middle upper and upper economic class. The solution was minimally processed vegetable dishes. Customer relationship strategy used social media promotion and customer service. These products were distributed through supermarkets. All results of research became into business model for company

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.
