Judul: Kajian Potensi Penerapan Strategi Produksi Bersih pada Industri Kayu Lapis : Studi Kasus di CV. Mekar Abadi, Wonosobo, Jawa Tengah
Abstrak: Plywood industry is an industry that has a problem toward the use of raw materials and large quantities of waste disposal. Therefore, the cleaner production strategies are needed to improve the efficient use of wood logs and energy and minimizing waste is wasted. The analysis includes three aspects. Analysis of technological techniques to see unit processes and machines production which is the source of waste, and produce cleaner production options as a solution. Financial analysis determines the priority of each of these production options and calculate the payback period. Political analysis is done using two methods, the analysis of SWOT (Strength, Weakness, Opportunity, and Threath) and Analitical Hierarchy Process that will result in cleaner production strategies. Analysis of technological techniques produces six priority cleaner production options. Financial analysis resulted in a total investment cost for six priority cleaner production options amounting to Rp 206,593,027. Advantages and savings gained Rp 65,210,649, with payback period for 3 months and 5 days. Political analysis produced seven strategies for implementation of cleaner production. Its main strategy is to socialize and training in the implementation of cleaner production and improving the quality of plywood. Thus, CV Mekar Abadi has great potential in the application of cleaner production as an environmental management strategy. The use of cleaner production strategies above can create CV Mekar Abadi as the sustainable plywood industry.

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.
