Judul: Product and Production Line Process Development of Mashed Potato in Modoinding Sub-District, South Minahasa.
Abstrak: Korporasi Petani Kecamatan Modoinding di Kabupaten Minahasa Selatan merupakan sekian dari komunitas petani yang memiliki aspirasi untuk mampu mengolah komoditas kentang yang dikultivasi secara mandiri menjadi produk dengan nilai tambah, baik akibat permasalahan dari komoditas itu sendiri maupun dalam harapan untuk mempertahankan keberlanjutan pertanian. Namun hingga kini Korporasi Petani belum memiliki gambaran yang jelas mengenai gambaran produk kentang yang dapat diproduksi secara industri, maupun tahapan proses yang mampu dijalankan. Di bawah naungan program Kementrian Pertanian Republik Indonesia berupa UPLAND, dijalankan inisiasi untuk menentukan produk turunan kentang terbaik berdasarkan orientasi ekonomi tersebut berupa mashed potato. Penelitian ini dilakukan untuk mengembangkan konsep mashed potato sebagai konsep berdasarkan berbagai modifikasi produk itu sendiri. Penelitian mendapatkan perumusan produk terbaik berdasarkan uji organoleptik dan penyesuaian dengan Standar Nasional Indonesia (SNI). Penelitian juga melakukan analisis dalam tiap tahapan proses pembuatan produk tersebut, yang secara kualitatif dan kuantitatif akan diterapkan dalam kapasitas produksi berdasarkan kapabilitas alat dan sumber daya yang tersedia. Pengembangan produk dan lini produksi ini kemudian akan dianalisis secara kelayakan finansial dalam penelitian terkait sebagai tahapan validasi secara ekonomis dalam kemampuan menyejahterakan Korporasi Petani Modoinding secara finansial berdasarkan orientasi program UPLAND., Modoinding Farmers Corporation are few of local farming community which aspires to transform their self cultivated potatoes as a commodity into a product with added value, whether due to the problem caused by the commodity or the desire to sustain the capability of farming itself. But until now, the corporation still yet to attain any form of which potato product could be produced with best economic advantage and the various step to process it industrially. Under the supervision of Indonesian Ministry of Agriculture, the UPLAND program is created to initiate the necessity of choosing the best potato-based product based on economic standpoint as mashed potato. This research was conducted to develop the conception of mashed potato as a concept into a product by various modification of its process. This research gathers the best product formulation by organoleptic comparison and referring national standarisation (SNI). This research also initiate analysis from each step of production process, evaluated by quantitative and qualitative means based on available resource and mechanical capability. Both product and its production line will then be analysed by financial visibility with correlated research as validation step by economic means to ensure industry’s ability to prosper financially as UPLAND’s orientation.

Judul: Financial Analysis of  Mashed Potato and Potato Flour Production Unit Development in Modoinding  Desctrict South Minahasa Regency
Abstrak: Produk mashed potato dan tepung kentang potensial untuk dikembangkan sebagai alternatif solusi dari permasalahan jumlah produksi dan rendahnya penyerapan pasar kentang di Minahasa Selatan berdasarkan aspek keberlanjutan usaha. Tujuan penelitian ini adalah menganalisis kelayakn finansial dan sensitivitas pengambangan unit produksi mashed potato dan tepung kentang. Metode yang digunakan pada penelitian ini adalah metode kuantitatif yang dimulai dari perhitungan Harga Pokok Produksi (HPP), penentuan harga jual, Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit Cost Ratio (Net B/C), payback period, dan analisis sensitivitas. Hasil perhitungan menghasilkan HPP sebesar Rp 47,182 untuk produk mashed potato dan Rp 59,739 untuk produk tepung kentang. Hasil perhitungan analisis kelayakan menghasilkan nilai NPV sebesar Rp1,346,988,430 nilai IRR sebesar 46%, Net B/C sebesar 1,24 dan Payback Period selama 0,75 tahun. Analisis sensitivitas yang dilakukan untuk pengembangan unit produksi ini menunjukkan bahwa peningkatan harga bahan baku sebesar 25% dan 50% serta penurunan harga jual sebesar 10% dan 20% tidak terlalu sensitif sehingga pengembangan unit produksi ini masih tetap layak untuk dijalankan., Mashed potato and potato flour products have the potential to be developed as an alternative solution to the problem of low production and low market absorption of potatoes in South Minahasa based on business sustainability aspects. The purpose of this study was to analyze the financial feasibility dand sensitivity of mashed potato and potato flour production unit development. The method used is a quantitative method which consists of calculating the Cost of Production (HPP), product selling prices, Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit Cost Ratio (Net B/C), payback period, and sensitivity analysis. The calculation results cost of production of IDR 47,182 for mashed potato product and IDR 59,739. The calculation financial feasibility results NPV value of IDR Rp1,346,988,430, IRR of 46 %, Net B/C of 1.24, and payback period of 0.75 years. The sensitivity analysis carried out for the development of this production unit shows that an increase in raw material prices by 25% and 50% and a decrease in selling price by 10% and 20% are not too sensitive so that the development of this production unit is still feasible.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
