<p>Pengangguran merupakan salah satu permasalahan utama yang dihadapi oleh banyak daerah di Jawa Timur , termasuk Kabupaten Pamekasan. Di kabupaten pamekasan pertumbuhan industri menjadi salah satu faktor yang dapat mengurangi tingkat pengangguran terbuka karena dapat menyerpa tenaga kerja. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana hubungan antara pertumbuhan industri terhadap tingkat pengangguran terbuka di kabupaten pamekasan. Data yang digunakan pada penelitian ini adalah pertumbuhan industri dan tingkat pengangguran terbuka pada tahun 2013 – 2023. Penelitian ini menggunakan regresi linear sederhana untuk mengatahui sejauh mana hubungan antara pertumbuhan industri terhadap tingkat pengangguran terbuka (TPT) di kabupaten Pamekasan. Hasil penelitian ini menunjukkan bahwa pertumbuhan industri berpanguruh negatif terhadap tingkat pengangguran artinya apabila pertumbuhan industri meningkat maka akan terjadi penurunan terhadap tingkat pengangguran terbuka begitupun sebaliknya.</p>

<p><em>This study aims to predict the amount of rice production in Pamekasan Regency using the Semi Average method. The data used are secondary data obtained from the Central Bureau of Statistics (BPS) of Pamekasan Regency, covering the observation period from 2015 to 2024. The analysis process began with processing historical rice production data using the method, followed by an evaluation of forecasting accuracy using the Mean Absolute Percentage Error (MAPE). The results of the analysis indicate that the Semi Average method produces a forecasting pattern with a MAPE value of 46.62%, which falls into the fair category based on MAPE interpretation, indicating a moderate level of accuracy. The results of this study are expected to serve as a reference for agricultural sector planning, particularly in managing sustainable rice production in Pamekasan Regency.</em></p>

<p><em>Indonesia is a country that is included in the target of high stunting management in the world, so stunting remains a problem that needs to be addressed. For example, the number of stunting in Pamekasan Regency. Currently, Pamekasan Regency is included in the target of stunting management with a stunting prevalence of 25.1% covering 21 health centers from 13 sub-districts. The purpose of this study is to predict the number of stunting in Pamekasan Regency in 2018-2024 using the statistical parabolic method. Statistical parabolic is one method that is able to make predictions based on past data, then in this study used data on the number of stunting in 2018-2024 obtained from the Pamekasan Regency Health Office. After calculating the predicted number of stunting in 2018-2024 based on the MAPE value obtained the result of 5.45%. Therefore, it can be concluded that the statistical parabolic method is good to be used to predict the number of stunting in 2025-2026.</em></p>
