Judul: Peningkatan mutu dan penerapan cara produksi pangan yang baikpada industri rumah tangga minuman temulawak instan di Desa Benteng, Ciampea, Bogor
Abstrak: This research was consisted of 5 steps i.e. to study the characteristic of Home Industrial Food Product (HIFP) of temulawak instant drink, to improve formulation and process of temulawak instant drink, to determine chemical characteristic of the product, certification of temulawak instant drink product of home industrial scale, and analyses of business feasibility. The first step was to determine the condition of Home industrial temulawak instant drink. The data of this step was used to improve formula and process to obtain standard formula. Besides, determination of Standarad Operating Procedure of home industrial of temulawak instant drink was carried out as further step of the improvement of formula and production process. The second step of this research was to analyse the chemical characteristic of the standard formula’s product using proximat analyses. The propose of certification of Home Industrial Food Product (HIFP) to was carried out as the fourth step. Finally, business feasibility analyses on home industrial scale was done to determine whether this business are feasible or not. Formula III (the ratio temulawak and sugar amount 1:2) was chosen as the most acceptable formula since it showed highest preference level as result of organoleptic test. This formula also had the shortest rehydration period and highest yield. The chemical and phsycal properties of instant temulawak are 1,06% of water content; 2,84% of ash content; 3,51% of fat content; 2,07% of protein content; 90,53% of carbohydrat content; and 33,09% of total sugar with L= +52,53; a= +3,29; b= +29,16 representating the color. This instant Coro has 0,428% of dissoluble part and 28 second for rehydration time. Home industrial of temulawak instant drink considered to be sufficient in GMP application and has acquired HIFP certificate with serial number of6123201021009 from governmental health department. The feasibility study based on investment criteria showed the production of instant temulawak was feasible to be done.

Judul: Analisis Kelayakan Pengusahaan Tempe Higienis (studi Kasus : Rumah Tempe Bapak Munawir di Kecamatan Cibungbulang, Kabupaten Bogor
Abstrak: Tempe merupakan makanan khas Indonesia. Saat ini, mayoritas pengrajin membuat tempe masih menggunakan cara yang konvensional, sehingga tempe yang dihasilkan kurang berkualitas. Tujuan penelitian ini adalah untuk mengkaji kelayakan aspek non finansial dan aspek finansial dalam merencanakan usaha pembutan tempe higienis. Pengambilan data dilakukan dengan metode purposive sampling, dengan kriteria pengrajin yang masih mengunakan cara konvensial dalam memproduksi tempe. Hasil penelitian menunjukan bahwa rencana pembuatan tempe higienis akan memberikan keuntungan. Perusahaan dapat menghasilkan NPV sebesar Rp 413 469 177 dengan IRR 53.62 persen, net B/C 3.51 dan payback period selama 2.77 tahun. Hasil analisis sensitvitas menunjukan bahwa bisnis lebih sensitif terhadap penurunan jumlah produksi. Analisis switching value menunjukan hasil batas maksimum kenaikan harga bahan baku kedelai sebesar 55.75 pesen dan penurunan jumlah produksi sebesar 49.32 persen.

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.
