Judul: Rancang Bangun Model Bisnis Finished Banknotes Perum Peruri Terintegrasi dengan Strategi Kesinambungan
Abstrak: Perum Peruri is a state-owned banknotes printing company that has a mandate from the government to print Rupiah notes ordered by Bank Indonesia (BI). Perum Peruri's highest income comes from banknote printing. Other income comes from printing security documents such as passports, stamps, excise duty, and land certificates. The high contribution of income from printing banknotes makes the position of Perum Peruri quite vulnerable to various changes in BI policy. For example, the implementation of the business model for providing Rupiah currency on a finished note or end to end is a BI policy that can potentially affect the sustainability of Perum Peruri's business. In addition, other factors can also affect the strategic environment of Perum Peruri, such as the impact of the shifting trend of payments from cash to digital, national economic growth, and extraordinary natural events such as the Covid-19 pandemic. This study is intended to determine the design of a new business model caused by changes in the strategic environment associated with the company's sustainability strategy. This study has 6 (six) objectives, each of which is interrelated. First, to identify and evaluate the current condition of Perum Peruri's banknotes printing business environment. Second, to formulate strategic assumptions for the upcoming Perum Peruri finished banknotes business model. Third, identify and describe the current Perum Peruri banknotes printing business model. Fourth, measure and formulate the maturity level of Perum Peruri's printing business continuity and Perum Peruri's finished banknotes business model perspective in the future. The fifth is to develop and recommend Perum Peruri's dynamic capabilities that support an integrated finished banknotes business model with sustainability. Finally, the sixth is to develop a design for an integrated sustainable Perum Peruri finished banknotes business model. The Issues Priority Matrix method is used to identify various issues that fall into the main priority category. Resources Based View is used to identify the company's internal resources that still need to be developed to support changes in the business model. Strategic Assumption Surfacing and Test analyzes various issues that fall into important and definite categories. Business Model Canvas is used to describe the company's business processes. Interpretive Structural Modeling is used to determine the perspective of the finished banknotes business model, the Sustainability Maturity Model is used to analyze the company's sustainability maturity level, and Dynamic Capability produces recommendations for configuring the internal resources owned in the face of environmental changes by making a company sustainability strategy. Sources of data and information are from BI, the Ministry of SOEs, Perum Peruri, and other parties in the ecosystem of the security printing industry. This research is expected to be a design for changing the business model of printing banknotes in the form of finished banknotes integrated with a sustainability strategy and become a reference for methodology and strategic studies for Perum Peruri in formulating models for other types of business. vii The research results are that changes to the finished banknotes business model are a priority issue that is categorized as necessary, very impactful, and has a very high level of certainty that it will occur, so

Abstrak: The aim of this research is to develop Model of Qualified and Environment Insight Printing Management. The detail of this aim are ; (1) to analysis and determine the factors of printing management,(2) to analysis the parameters and standards of printing quality and printing waste management, (3) to design the sub model of qualified printing management and the sub model of printing waste management, and (4) to formulate the strategy of qualified and environment insight printing management. Novelty of this research is to obtain the joining factor between two sub model. The first one is qualified management and the second one is waste management in printing company. Another novelty in this study is the parameter of qualified management sub model and parameter of waste management in printing company. This research used primary and secondary data. Modelling approach is used as research method. Primary data is collected by individual and group interview which is guided by structural questionnaire, direct observation, and Focus Group Discussion (FGD). Secondary data such as printing management and public policy, waste management, and environment management, are collected by literature review, report exploring, and measuring from institutional that related to printing management. Tools of analysis in this study are Policy analysis, verification, and Quantitative Strategic Planning Matrix (QSPM). To arrange the model, the first step is to determine the management factors and the result are as below : drafts, raw materials, machines, human resources, finance, production process, product, solid waste management, and liquid waste management. For each factors, there are some parameters and standards which are related to qualified printing company. The model of this study is the model of qualified and environment insight of printing management. This model is develop from the whole system in strategic planning of qualified and environment insight printing management. As a tool of decision making, this model can be used to verify and prove the actual performance of three different scale of printing company. This model can also be used to solve the quality problem for these companies. Verification in PT Percetakan Gramedia (as a large scale printing) result that this company has “good” performance with deviation value 8,89%, and there are two strategies for it. Verification in PT Percetakan Penebar Swadaya (as a medium scale printing) result that this company has “no good” performance with deviation value 17,64%, and there are four strategies for it. Verification in Percetakan IPB Press (as a small scale printing) result that this company has “no good” performance with deviation value 44,16%, and there are nine strategies for it. Implementation of this model can help the user in information availability which is useful for decision making effectively. With this strategy as a tool of company policy, the company can improve its performance to achieve qualified and environment insight of printing management.

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.
