Judul: Pengembangan Pasar Produk Beras Cepat Masak
Abstrak: Penelitian ini berawal dari permasalahan konsumsi yang dihadapi oleh komunitas pecinta alam. Tujuan dari penelitian ini yaitu mengidentifikasi masalah yang dihadapi pecinta alam saat membawa dan mengolah beras serta merancang solusi pada permasalahan tersebut dengan produk beras cepat masak. Metode yang digunakan pada penelitian ini adalah riset aksi dengan menggunakan pendekatan kualitatif. Tahapan dari penelitian terdiri dari perancangan kanvas model bisnis awal, pengujian masalah dengan 50 responden, pengujian solusi dengan responden potensial, pengukuran ukuran pasar, dan verifikasi. Permasalahan utama pada penelitian ini, yaitu berat saat membawa beras dan air, boros penggunaan air, membutuhkan perlakuan khusus saat memasak nasi, lama waktu memasak nasi, relatif sering gagal dalam memasak nasi dan alat masak (nesting) yang sulit dibersihkan. Beras cepat masak adalah produk yang ditawarkan untuk menjadi solusi dari permasalahan tersebut. Hasil pengujian solusi dari produk beras cepat masak menunjukkan kesesuaian value proposition yang diberikan kepada pelanggan yaitu praktis, tidak gagal dalam memasak nasi, tidak mengotori alat masak (nesting), hemat air dan tidak berat. Harga penjualan yang diterima oleh konsumen, yaitu Rp13.500/kemasan (6*42 gr).

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: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
