Abstract

The partition dimension of a graph is determined by minimum number of vertex partitions such that every vertex has different distances to the ordered partitions. A complete graph is very easy to determine its partition dimension because each vertex has the same distance to other vertices. However, what are the partition dimension if a complete graph is modified so that it becomes a daisy graph. In this paper, we discuss the partition dimension of daisy graphs. Next, we will also provide barbell graph operations on daisy graphs.

Abstract

This study aims to describe and analyze Islamic Religious Education (PAI) teachers' perspectives on implementing inclusive education at Public Elementary Schools (SDN) in Sungai Rengas Village. The phenomenon of inclusivity in education requires the active role of teachers, including PAI teachers, in shaping the character of all students, including those with special needs. The problem arises when understanding and support for implementing inclusive education in practice remain limited. This study offers a solution that strengthens PAI teachers' competencies through continuous training and collaboration among relevant stakeholders. The study uses a qualitative approach with a case study method. Data collection techniques include observation, in-depth interviews, and documentation involving PAI teachers and related parties at the school. PAI teachers have a reasonably good understanding of the concept of inclusive education. Their main challenges include a lack of training, limited facilities and infrastructure, and minimal support from assistants. Nevertheless, the teachers are firmly committed to providing fair and inclusive learning services. PAI teachers at SDN Sungai Rengas show good awareness and commitment to inclusive education despite facing various obstacles to its implementation. This research also provides empirical insights into the roles and challenges of PAI teachers in the context of inclusive education. The findings can be a foundation for developing teacher training policies and strengthening stakeholder collaboration to support effective inclusive education.

Abstract

Catalan numbers, denoted by Cn, are generally defined by the equation Cn = 1/(n+1) (2nn) with n ≥ 0 and n ∈ ℤ. Catalan numbers have forms that can be determined through generaland recursive forms. Catalan numbers have several applications to various combinatorialproblems, such as in recursive analysis and the application of combinatorial theory topartitions that can form Catalan numbers. The odd numbers are defined as integers that arenot divisible by two, expressed in the form {2k + 1; k ∈ ℤ} . Meanwhile, even numbers aredefined as integers that are divisible by two, expressed in the form {2k; k ∈ ℤ} . In this studywe discuss the noncrossing partitions of positive odd numbers and positive even numbers.The results show those the noncrossing partitions have relationship with Catalan numbers.

Abstract

The take or pay contract between PT. PLN (Persero) with Independent Power Producer (IPP), a power plant belongs to PT. PLN (Persero) is no longer operated optimally, for example, the Barru steam power plant. The steam power plant is a power plant that bears the primary load. The actual conditions in the Barru steam power plant field are charged a maximum of only 3-4 hours or only when the peak load is according to the dispatcher's request. This research examines comparing the economy dispatch method to maximize conditions in the Barru steam power plant, which dispatchers no longer order maximally. So that the Barru power plant operator can determine the distribution of the power allocation ordered by the dispatcher to the two power plant units of the Barru steam power plant, the method being compared is the lambda iteration method. The basis for calculating the two ways is to calculate in advance the characteristics of the fuel consumption of the power plant when operating in one day. The primary data is data on the results of electricity production issued by the generator and fuel consumption taken from the coal feeder flow. Based on the research results, it is known that the lambda iteration method can save production costs of Rp. 9.05 per KWH.
