Abstract

Penelitian ini bertujuan untuk melakukan pemetaan kemiskinan di Kabupaten Mukomuko ProvinsiBengkulu. Metode yang digunakan dalam penelitian ini adalah Small Area Estimation (SAE) denganpendekatan regresi Penalized Spline (P-Spline). Pendugaan parametr model dasar SAE umumnyamembangun suatu model linier campuran yang mengasumsikan bahwa variabel respon dan variabelprediktor mempunyai hubungan linear. Ketika asumsi tersebut tidak terpenuhi, maka dilakukanpendekatan nonparametrik sebagai alternatif pilihan. Salah satunya adalah pendekatan nonparametrikP-Spline. Pada penelitian ini, dilakukan pendugaan parameter model menggunakan P-Spline sehinggadiperoleh suatu persamaan regresi efek campuran sebagai model SAE. Selanjutnya model tersebutdigunakan untuk menduga tingkat kemiskinan pada area yang tersampling., sehingga diperoleh pendugatingkat kemiskinan pada level desa di Kabupaten Mukomuko yang disajikan dalam bentuk petakemiskinan. Hasil penelitian menunjukkan pendugaan menggunakan model SAE dengan P-Splinememiliki trend (kecenderungan) yang sama dengan penduga langsung. Kecamatan yang memiliki tingkatkemiskinan tinggi menyebar di bagian Timur Laut dan Tenggara dari Kabupaten Mukomuko, yaituKecamatan Selagan Raya, Teramang Jaya, Pondok Suguh, dan Air Rami masing-masing memiliki rata-rata kemiskinan yang tinggi. Sedangkan kecamatan dengan tingkat kemiskinan rendah adalahKecamatan Lubuk Pinang.

Abstract

The first objective of this activity is to increase knowledge and understanding of the rescue procedures, evacuation routes, and emergency response plans when a large earthquake occurs. The second objective is to increase the knowledge and ability to mobilize available resources. With this knowledge and capability, the community can choose and sort out the resources that must be prioritized, so that losses can be reduced as little as possible. Referring to the results of the study, reducing the impact of earthquake and tsunami disaster risk is greatly influenced by emergency response plan factors, disaster warning system factors, knowledge factors, policy and guidance factors, and the ability of team mobilization. The conclusion obtained from the results of this activity is that the Air Rami Sub-district community gained increased knowledge and understanding of earthquake and tsunami mitigation. This can be seen from the enthusiasm of stakeholders and the public in participating in socialization activities. It is also supported by the Wilcoxon statistical test, the result showed that socialization increases public knowledge in understanding disaster mitigation, especially earthquakes and tsunamis.

Abstract

Small Area Estimation is a statistical method used to estimate parameters in sub-populations with small or even no sample sizes. This research aims to evaluate the Beta-Binomial model's performance for estimating small areas at the area level. The estimation method used is Hierarchical Likelihood (HL). The data used are simulation data and empirical data. Simulation studies were used to investigate the proposed model. The estimator's Mean Squared Error of Prediction (MSEP) and Absolute Bias (AB) estimator values determine the best estimation criteria. An empirical study using data on the illiteracy rate at the sub-district level in Bengkulu Province. The results of the simulation study show that, in general, the parameter estimators are nearly unbiased. Proportion prediction has the same tendency as parameters. Finally, the HL estimator has a small MSEP estimator. The results of an empirical study show that the average illiteracy rate in Bengkulu province is quite diverse. Kepahiang District has the highest average illiteracy rate in Bengkulu Province in 2021.

Abstract

Upaya yang dilakukan pemerintah untuk meningkatkan kemampuan numerasi ialah dengan menerapkan tes Asesmen Kompetensi Minimum (AKM). Hasil wawancara terhadap satu orang guru SMP N 07 Kota Bengkulu, menunjukkan sekolah belum mempersiapkan secara khusus dalam menghadapi tes AKM. Berdasarkan hasil wawancara, siswa yang masuk SMP N 07 ialah anak warga sekitar yang yang memiliki keterbatasan kondisi sosial, ekonomi, teknologi dan kemampuan yang kurang. Untuk pembelajaran daring siswa hanya mampu menggunakan whatsapp ataupun SMS, siswa dan guru sebagian besar tidak memiliki laptop serta jaringan internet WIFI sehingga dampak pembelajaran daring sangat dirasakan oleh siswa. Siswa banyak yang belum lancar menerapkan ilmu matematika dalam soal cerita sehingga nilai matematika siswa secara keseluruhan turun saat pembelajaran daring bahkan kemampuan literasi matematika (Numerasi) sangat rendah. Kegiatan pengabdian ini diyakini dapat meningkatkan kemampuan literasi matematika dan mengurangi dampak pembelajaran daring maupun luring sistem shift karena pandemi Covid-19. Kegiatan ini akan membuat siswa menjadi melek literasi numerasi. Agar kegiatan ini menjadi efektif dan efisien maka akan digunakan beberapa rencana kegiatan seperti adanya buku saku/modul, video edukasi, penyelesaian menggunakan software matematika dan kegiatan berbentuk games. Hasil analisis pretest dan postest menggunakan uji-t menyatakan bahwa ada perbedaan yang nyata antara sebelum dan sesudah diberikan pelatihan terhadap siswa SMP N 07 Kota Bengkulu.

Abstract

PT Cipta Graha Garwita (CGG) is a palm oil producer focused on product quality, especially crude palm oil (CPO) for both food and non-food applications. Despite CGG's good reputation, variability in quality characteristics such as Free Fatty Acid (FFA) and moisture can affect the final quality of CPO. This study aims to apply a statistical quality control system to monitor and improve the consistency of CPO quality using T² Hotelling control charts. Statistical quality control methods ensure that products meet standards by reducing variability. One such tool is the T² Hotelling control chart, effective for monitoring multivariate variables using mean vectors and variance-covariance matrices. This study involves steps from data collection, testing multivariate normality assumptions, calculating T² Hotelling control charts, to determining control limits. Testing for multivariate normality assumptions showed the data met normal distribution criteria. The first and second stage T² Hotelling control charts identified several out-of-control observations. These out-of-control observations were excluded, and further analysis showed that after their removal, all data were within statistical control limits. This study recommends further analysis to determine the causes of out-of-control observations using Ishikawa diagrams and process capability evaluation to ensure consistent product quality.
