Judul: Kelayakan Dan Strategi Pengembangan Usaha Pembibitan Sagu Oleh Pt Y Di Lokasi Perkebunan Sagu Pt X
Abstrak: Indonesia has a variety of plants that produce carbohydrates, both derived from the grain and the rod such as sago and palm sugar. Seeing a great opportunity of sago utilization, Company X (X) developed sago plantation in peatlands located in Meranti District, Riau Province. X cooperates with Company Y (Y) to establish nursery and planting activities to meet the growing needs of the sago planting. This study aims to analyze financial feasibility and determine business development strategy of sago nursery by Y. Analytical methods used are: (1) Financial feasibility analysis through the Net Present Value (NPV), Payback Period (PBP), Internal Rate of Return (IRR), Profitability Index (PI) and Break Event Point (BEP), (2) Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis to determine strategy alternatives, and (3) Analytical Hierarchy Process (AHP) to determine the priority of selected strategies. The results of financial feasibility analysis shows calculated NPV (-Rp2.084.067.814) and PI (0.69), then the sago nursery business are considered not feasible. It will be considered to be feasible if Y made improvements in nursery and cultivation techniques to reduce the mortality rate or renegotiate the purchase price to X. Alternatives strategy that can be selected by Y is an intensive strategy, through product development. This is consistent with the analysis of Internal – External (IE) matrix that shows Y is in grow and build position. Priority business development strategy based on AHP is to 1) Increase production and decrease mortality rate (0.486), 2) Improve nursery and planting techniques (0.230), 3) Improve coordination and cooperation (0.150), and 4) Planting during the rainy season (0.134). Several advices have been proposed to Y are to 1) Perform technical improvements in nursery and planting to reduce mortality rate, 2) Renegotiate purchase price, and 3) Implement strategies that lead to product development by improvements in nursery and sago planting techniques.

Judul: Pengelolaan perkebunan sagu (Metroxylon spp) di PT. National Sago Prima, Selat Panjang, Riau: seleksi bibit sagu berdasarkan jenis, tinggi pohon induk dan bobot bibit sagu terhadap pertumbuhan bibit sagu di persemaian
Abstrak: Sago nursery is a special factor that performed during the internship activities at PT. National Sago Prima, Selat Panjang, Riau. The experiment was conducted to obtain information in a nursery on the effects of this type of sago, height of mother plant sago and weight of sucker. The type of sago used was spiny sago (S1) and sago without spiny (S2). Height of mother plant used was 3.3 m - 4.6 m (T1), 4.6 m - 6.6 m (T2), more than 6.6 m (T3) and mother plant that have been harvested (T4). Sucker Weight used was 0,5 kg – 1,5 kg (B1), 2 kg – 3 kg (B2) dan 3,5 kg – 4,5 kg (B3). The results shown sago without spiny is better than spiny sago, height of mother plant is not effect significantly and sucker weight 3,5 kg – 4,5 kg is better than two other sucker weight. During the internship activities, sago cultivation activities conducted to obtain primary data. Secondary data were obtained by conducting interviews, discussions and reading of literature contained in the company.

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.
