Abstract

Penelitian ini membahas tentang peramalan jumlah penderita Demam Berdarah Dengue (DBD) menggunakan metode Seasonal Autoregressive Integrated Moving Average (Seasonal-ARIMA). Tujuan dari penelitian ini adalah untuk mendapatkan model Seasonal-ARIMA terbaik sehingga dapat meramalkan jumlah penderita DBD di Kabupaten Bulukumba untuk 12 bulan ke depan. Jenis penelitian ini adalah penelitian terapan dengan data sekunder yang diperoleh dari Dinas Kesehatan Kabupaten Bulukumba. Jumlah data yang digunakan adalah 84 data dari tahun 2014-2020. Data dianalisis dengan menggunakan software Minitab 17. Hasil penelitian ini diperoleh model terbaik yaitu model Seasonal-ARIMAuntuk melakukan peramalan 12 bulan ke depan dengan nilai MAPE sebesar 30,62% yang berarti bahwa model peramalan cukup baik, layak dan memadai untuk melakukan peramalan.

Abstract

Perbedaan karakteristik pada setiap kabupaten/kota di Provinsi Sulawesi Selatan menyebabkan terjadinya heterogenitas spasial sehingga metode regresi linear global menjadi kurang tepat digunakan pada data spasial dan metode Geographically Weighted Regression (GWR) lebih cocok digunakan. Tujuan penelitian ini adalah untuk mengetahui karakteristik Angka Buta Huruf (ABH) di 24 kabupaten/kota di Provinsi Sulawesi Selatan dan variabel-variabel yang mempengaruhinya dengan menggunakan GWR. Variabel prediktor yang digunakan adalah persentase penduduk miskin (PPM), angka partisipasi sekolah (APS), rata-rata lama sekolah (RLS), jumlah tenaga pendidik (JTP), dan persentase penduduk yang memiliki telepon seluler (PMTS). Teknik pengumpulan Data menggunakan metode dokumentasi. Data dianalisis menggunakan statistik deskriptif dan inferensial menggunakan metode Weighted Least Square (WLS). Hasil penelitian ini menunjukkan bahwa model GWR (koefisien determinasi 86,1%) lebih baik dalam menjelaskan angka buta huruf dibandingkan dengan model regresi linear berganda (koefisien determinasi 69,2%). Koefisien regresi dan variabel yang mempengaruhi angka buta huruf berbeda pada setiap lokasi, estimasi parameter berlaku secara lokal. Lokasi yang saling berdekatan cenderung memiliki pengaruh variabel prediktor yang sama, kecuali pada kota Palopo, Tana Toraja, dan Toraja Utara tidak memiliki pengaruh variabel prediktor yang signifikan.

Abstract

The purpose of this study is to determine whether the case study methodology has a substantial effect on students' problem-solving skills when compared to traditional learning approaches. The research sample consisted of 56 students divided into two groups: experimental (taught using the case study approach) and control (taught using the traditional method). The quantitative quasi-experiment approach was applied in this study. The experimental class had an average value of 70.7143, whereas the control class had an average value of 62.1429. The independent t-test yielded a significance value of 0.055, suggesting a degree of significance lower than the standard criterion of 0.05. The key conclusion of this study is that employing case studies improves soft skills during the learning process. However, the development of pupils' hard skills is still seen as minor. This study contributes to a better understanding of the influence of the case study technique on problem-solving learning. These findings may be used to provide practical recommendations to increase the efficacy of learning methodologies in acquiring both types of abilities. More study is needed to investigate the elements that impact the observed outcomes and increase the statistical significance in the development of students' skills.

Abstract

The purpose of this study is to compare the efficacy of the Problem-Based Learning (PBL) learning model to traditional learning in developing the competence to manage Hazardous and Toxic Materials (B3) in basic laboratory courses. In this form of experimental research utilizing a Pre-Test and Post-Test Control Group Design, The N-gain values in the experimental (0.774) and control (0.8163) groups increased significantly, with g> 0.7 indicating a high category. The N-gain percent in the experimental (77.4026) and control (81.627) courses topped 76%, showing that both learning approaches were effective. Even though the Mann-Whitney non-parametric test revealed no significant difference between the experimental and control groups on the posttest and pretest, the conclusion that PBL had no meaningful impact must be regarded in the context of this study. Overall, both PBL and traditional methods improved B3 handling abilities, and these findings may aid in the creation of more effective learning methodologies in the future.

Abstract

This type of research is a pure experimental type of research and uses a quantitative experimental approach, which aims to: (1) find out whether there is an effect of dry banana leaf waste media and the addition of molasses on the growth of white oyster mushrooms (Pleurotus ostreatus), (2) find out how many treatments dry banana leaf waste media and the addition of molasses which gave the best results for the growth of white oyster mushrooms (Pleurotus ostreatus). This research was structured in a Completely Randomized Design (CRD) with a single factor consisting of 7 treatments and carried out 4 times. Thus, there are a total of 28 baglogs/experimental units. The data analysis technique used is an analysis of variance (ANOVA) with a further test using the Least Significant Difference (BNT). The results of the research showed that the planting medium of dried banana leaf waste and the addition of molasses had a real effect on the initial time of mycelium growth (HSI), and the time to pour the mycelium (full colony) (HSI), and had no real effect on the width of the cap (cm), length ( cm), and wet fruit body weight (gr) of white oyster mushroom (Pleurotus ostreatus). The best treatment results on dry banana leaf waste planting media and the addition of molasses to the fastest initial growth time of the mycelium were in treatment (D2) (4.25 HSI), and the fastest time of heating the mycelium (full colony) was in treatment D0 (29 DAS). Meanwhile, D5 was the best treatment for hood
