Abstract

The rapid development of cellular communication technology is inseparable from various problems especially on signal quality. In outdoor areas, the performance of eNodeB that is not optimal may cause communication failure. This research was conducted with the drive test on the L_BUNDARANRENON_PL, L_AKABA_PL and L_MYAMIN_CR to obtain signal quality parameters at Renon cluster area. The results of the drive test obtained compared to the simulation using the Atoll radio planning software with the Hatta Cost-231 propagation model and the Standard Propagation Model. From the comparison results, the margin value is used as a correction factor. The comparison results obtained based on the quality of SINR, The result of using the Standard Propagation Model is closer to the drive test measurement results than using Cost-231 Hatta. However, based on the quality of RSRQ, both propagation models yield almost the same results. Here are found that the correction factor for SINR obtained the Cost-231 Hatta propagation model of 6.15 dB and the Standard Propagation Model model of 6.11 dB. While for RSRQ correction factor the margin for both propagation models is -2 dB

Abstract

Background : Stunting remains a significant chronic nutritional problem in Indonesia, particularly among children born to adolescent mothers. These young mothers often face limitations in nutritional knowledge, lower health literacy, and suboptimal reproductive preparedness, which collectively increase the risk of stunting in their children. Objective : This study aimed to conduct a review to determine the association between adolescent mothers’ nutritional knowledge and the incidence of stunting in toddlers, and to identify the contributing factors. Research Methods/ Implementation Methods : This was a systematic review conducting following the PRISMA guidelines and utilizing the Population, Concept, and Context (PCC) framework. Articles were collected through searching the Scopus, PubMed, Google Scholar, and Crossref databases for studies up to October 2025. Two reviewers independently screened and included full- text article that examined Mothers Knowledge and stunting, focusing on the concept of knowledge, adolescent mother, and stunting. Results : A review included five articles. Adolescent mothers’ knowledge had a significant association with the incidence of stunting. This association was often strengthened by confounding factors such as socio-economic status, low education levels, limited access to healthcare services, and inadequate childcare practices. Several studies found that improving maternal nutritional literacy and initiating early prenatal care can effectively reduce the risk of stunting in children. Conclusion/Lesson Learned : Low nutritional knowledge among adolescent mothers is confirmed as an important determinant of stunting in toddlers. Intervention efforts need to be focused on enhancing the education and nutritional literacy of adolescent girls through structured programs, including school-based education, adolescent mother classes in community health centers (Puskesmas), and targeted community campaigns. The integrated approach is crucial to break the intergenerational cycle of stunting and foster the development of quality human resources.

Abstract

This study aims to conduct an in-depth analysis of the learning difficulties experienced by fifth-grade elementary school students in solving length unit calculations. The background of this study is based on students’ still-low ability to understand basic concepts of length units and to convert between units, which leads to errors in solving math problems. This study employs a qualitative approach using a descriptive method. The research subjects were fifth-grade students at a selected elementary school chosen through purposive sampling. Data collection techniques included written tests, in-depth interviews, and documentation. Data analysis was conducted through the stages of data reduction, data presentation, and drawing conclusions. The results of the study indicate that students’ learning difficulties encompass three main aspects: conceptual difficulties, procedural difficulties, and difficulties in problem-solving. Conceptual difficulties are evidenced by students’ low understanding of the relationships between units of length. Procedural difficulties are evident in errors when performing conversion steps and arithmetic operations. Meanwhile, difficulties in problem-solving were evident in students’ inability to understand word problems related to units of length. Additionally, misconceptions were identified, such as errors in using the unit conversion ladder and inaccuracies in determining the appropriate operations to use. Factors contributing to learning difficulties include internal factors
