Abstract

Inflation is important to be analyzed due to its impact is felt across various aspects of the economy and individuals' lives. This research aimed to develop robust and reliable predictions concerning Indonesian inflation using the bias-corrected bootstrap method for an AR model. The data utilized spanned from January 2020 to September 2023 and was obtained from Bank Indonesia's website. The analysis provided the optimal order in the AR model, which resulted in p=2 as the best order (AIC=-1.858, BIC=-1.698, and HQ=-1.798). The number of bootstrap replications used was B=100, 250, 500, and 1000. The analysis was conducted using R Studio. The analysis results indicated that the model employed for prediction analysis was highly stable, with all point forecasts indicating result consistency. The prediction results suggested that inflation in Indonesia was expected to decrease in the upcoming 5 months. The results also revealed that the bias-corrected bootstrap approach could provide forecasting results with a higher level of accuracy. This research contributed to the understanding and forecasting of Indonesian inflation, emphasizing model stability and consistent results.

Abstract

Adolescent girls are at high risk of experiencing nutritional problems, one of which is chronic energy deficiency (CED). Inadequate nutrient intake during adolescence will have an impact on health in subsequent life stages, namely adulthood (pregnant mothers) and old age. One of the efforts that can be done to address nutritional problems in adolescent girls is to change their behaviors by enhancing their knowledge through nutrition education. One of the nutritional education media used for targeting adolescent girls is the social media platform Instagram. The aim of this research was to determine the effect of balanced nutrition counseling using the social media platform Instagram on knowledge, energy intake, and protein intake among high school adolescent girls. The intervention was conducted for a total of 9 days over a period of 18 days. This study is a quasi-experiment with a two-group pre-test and post-test design. The treatment group was provided with the social media platform Instagram, while the control group was provided with PowerPoint media. The sample size consisted of 64 participants divided into two groups: the treatment group and the control group, using purposive sampling method. The data were analyzed using the Wilcoxon test, Dependent t-test, Independent t-test, and Mann-Whitney test. The research findings revealed that there was an influence of nutrition counseling on knowledge, energy intake, and protein intake in the treatment group. Similarly, there was an influence of nutrition counseling on knowledge, energy intake, and protein intake in the control group. There was a difference in knowledge between the treatment group and the control group among adolescent girls. However, there was no difference in energy intake and protein intake between the treatment group and the control group among adolescent girls. Periodic and continuous nutrition counseling is necessary to observe significant changes in energy intake and protein intake.

Abstract

Proses pembelajaran dipengarui oleh tingkat keseriusan atau konsentrasi. Faktor yang mempengaruhi diantaranya sarapan dan asupan zat besi. Sarapan mempengaruhi kadar glukosa dalam darah yang menjadi sumber energi yang berdampak pada kerja otak yaitu kemampuan dalam berkonsentrasi. Kekurangan zat besi akan menyebabkan peredaran oksigen dalam tubuh menjadi rendah sehingga tubuh menjadi mudah pusing, lelah, letih dan lesu serta berkurangnya kemampuan untuk berkonsentrasi dalam berpikir. Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara kebiasaan sarapan dan asupan zat besi dengan konsentrasi belajar Mahasiswa Jurusan Gizi Poltekkes Kemenkes Bandung. Desain penelitian yang digunakan adalah cross sectional dengan pengambilan sampel menggunakan teknik proportional random sampling. Sampel yang diganakan sebanyak 45 orang. Hasil penelitian menunjukkan tidak ada hubungan yang bermakna antara kebiasaan sarapan dengan konsentrasi belajar (p=0,937) karena nilai p>0,05. Tidak ada hubungan yang bermakna antara asupan zat besi dengan konsentrasi belajar (p=0,889) karena nilai p>0,05. Saran untuk penelitian ini adalah untuk penelitian selanjutnya disarankan responden bukan mahasiswa gizi, mengidentifikasi lebih lanjut mengenai faktor lain yang lebih berpengaruh pada konsentrasi belajar, dan responden membiasakan sarapan dan memperhatikan asupan zat besi agar dapat meningkatkan konsentrasi belajar.

Abstract

The pandemic of COVID-19 had a profound impact on the lives of families worldwide, including Muslim families in Indonesia. This study analyzes the resilience of multidimensional Muslim families in Indonesia during the COVID-19 pandemic. It has also been linked to family resilience in preventing divorce, which has reportedly increased during the COVID-19 pandemic. This study uses a qualitative approach. Observation techniques and in-depth interviews are conducted to obtain primary data. There are 25 interviewees. The findings indicate that three dimensions, namely the individual, family, and community dimensions, influence the resilience of multidimensional Muslim families during the COVID-19 pandemic. There is a positive causality relationship between the three interconnected dimensions. The findings suggest that all three can be used to prevent divorce by increasing resilience in these three dimensions. The analysis also reveals a spike in domestic violence, which is the cause of divorce during the COVID-19 pandemic. Domestic violence affects not only wives but also husbands.
