Abstrak: Business practices from the 20th century are irrelevant in today's VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) environment. VUCA represents the speed of change, unpredictability, complexity, and ambiguity situation in business. Volatility represents swift shifts, uncertainty entails an inability to foresee outcomes, complexity involves multifaceted considerations, and ambiguity signifies lack of clarity. Lean approaches, which prioritize efficiency, may fall short in dynamic, uncertain settings. Instead, agility is essential for organizations to adjust to new technology, customer needs, and market dynamics. Agility is both a mindset and method, emphasizing collaboration, continuous learning, and adaptability. Its adoption poses challenges due to entrenched structures and beliefs. The agile mindset embraces values like respect, courage, collaboration, and customer-centricity, necessitating a shift from traditional, schedule-driven approaches. Business agility enables swift responses to market changes, delivering value to customers. This study focuses on agro-industry's role and challenges in achieving business agility, particularly Indonesia's chicken meat sector. The agro-industry, especially downstream activities, boosts output and value, critical for food security, economic stability, and national well-being. The poultry sector, a subset, significantly contributes to the national economy through GDP (Gross Domestic Product) share and job creation. It drives industrial growth, meets protein demand, and links the food and processing sectors. Despite dominance by integrated players, small and medium actors participate too. Agro-industry encounters VUCA's rigid structures, bureaucracy, and change resistance. The chicken meat industry faces distinct obstacles like intricate supply chains, demand-supply imbalances, and oversupply challenges. Focusing on downstream segments, like processing, is vital to sustainability. This industry significantly impacts consumers, shaping affordable protein sources and staple foods, particularly in Indonesia. Hence, this research is developing a “BUSINESS AGILITY SYSTEM MODEL” for the chicken meat industry, which will form the basis reference for how a chicken meat business operates in a customer-oriented manner and act in business agility ways by focusing on the people's perspective. The main objectives were developed for three specific objectives that answer three research questions, namely: (1) To identify the VUCA situation experienced by the chicken meat industry, (2) To measure the current business agility index for the chicken meat industry, (3) To design the business agility model for the chicken meat industry, and (4) To develop the Agilist model for the chicken meat industry. This study analyzes the VUCA situation experienced in the chicken meat industry with rich picture. Developed Business Agility Index (BAI) self-asessment framework using analytical hierarchy process (AHP). Measurement of BAI adopted from the Lean, Agile, Resilient, and Agile (LARG) index method. Identification key challenges and enablers to achieving business agility using Interpretative Structural Model (ISM), and business agility system model development using business agility conceptual model from Soft System Methodology (SSM) results. This study succeeded in describing and providing an overview of the VUCA situation experienced by the chicken meat industry. The current BAI of the chicken meat industry has been measured. BAI is a metric that assesses an organization's ability to adapt and thrive in a fast-changing business environment. It considers factors like innovation, customer responsiveness, decision-making speed, and adaptability. To measure the BAI, a framework was created with four dimensions:

Judul: Graf Pembagi-Nol Planar dan Tak-Planar
Abstrak: Graf pembagi-nol adalah suatu graf yang dibentuk dari himpunan pembaginol pada ring. Graf pembagi-nol terdiri atas himpunan simpul yang merupakan elemen-elemen pembagi-nol dari ring, serta dua simpul adjacent jika dan hanya jika hasil kalinya sama dengan nol. Graf pembagi-nol dapat digambarkan dalam sebuah bidang sedemikian rupa sehingga tidak ada dua sisi yang saling berpotongan. Graf pembagi-nol ini disebut sebagai graf planar. Karya ilmiah ini menjelaskan pembuktian teorema bahwa jika suatu graf pembagi-nol mempunyai graf yang isomorfik dengan graf lengkap dengan lima simpul atau graf bipartite lengkap dengan masing-masing himpunan simpul sebanyak tiga simpul, maka graf pembagi-nol ini bersifat tak-planar. Karya ilmiah ini juga membuktikan beberapa graf pembagi-nol merupakan graf planar atau tak-planar.
