Abstract

The Covid-19 pandemic has caused instability in all sectors of the economy, especially in the agricultural sector. Lamongan Regency is one of the provinces in East Java which has the largest rice and rice yields in East and National Java. With this achievement, it is hoped that Lamongan Regency can maintain food security in the region. This study uses a qualitative descriptive analysis, the purpose of this study is to analyze the conditions and the role of the community and the government in the economic recovery of Lamongan Regency during Covid19 so that the food supply in the region remains fulfilled. The results of this study indicate that food conditions in Lamongan Regency are quite fulfilled during the pandemic, this is evidenced by the increase in harvest yields every year. The efforts of the community and the government of Lamongan Regency are to always pay attention to the distribution of food needs and the welfare of farmers in the Lamongan Regency area properly.

Abstract

Petani berperan dalam pembangunan nasional. Petani juga berperan penting dalam memenuhi kebutuhan pangan masyarakat. Sumber Daya Manusia di sektor pertanian yang mempunyai kualitas yang baik merupakan salah satu faktor penentu kemajuan pembangunan sektor pertanian. Tetapi, pembangunan sektor pertanian di Indonesia menghadapi masalah yang cukup serius, yaitu minimnya generasi muda yang enggan untuk bekerja dalam sektor pertanian. Penulisan artikel ini bertujuan untuk menganalisis minimnya tenaga kerja usia muda terhadap sektor pertanian sehingga berdampak buruk terhadap ketahanan pangan di Indonesia. Penulis menggunakan metode kualitatif karena berhubungan langsung dengan kehidupan manusia secara fundamental yang bergantung pada observasi. Hasil dari penelitian ini menunjukkan bahwa minimnya tenaga kerja usia muda dalam sektor pertanian dikarenakan kurangnya minat dan kepercayaan akan sektor pertanian yang dianggap kurang menjanjikan untuk masa depan. Namun, tenaga muda dalam sektor pertanian sangat dibutuhkan untuk memepertahankan serta memajukan pangan di Indonesia.

Abstract

Music genre classification plays a pivotal role in organizing and accessing vast music collections, enhancing user experiences, and enabling efficient music recommendation systems. This study focuses on employing the K-Nearest Neighbors (KNN) algorithm in conjunction with Mel-Frequency Cepstral Coefficients (MFCCs) for accurate music genre classification. MFCCs extract essential spectral features from audio signals, which serve as robust representations of music characteristics. The proposed approach achieves a commendable classification accuracy of 80%, showcasing the effectiveness of KNN-MFCC fusion. Nevertheless, the challenge of overlapping genres, particularly rock and country, demands special attention due to their shared acoustic attributes. The inherent similarities between these genres often lead to misclassification, hampering accuracy. To address this issue, an enhanced feature engineering strategy is devised, leveraging deeper insights into the subtle nuances that differentiate rock and country music. Additionally, a refined KNN distance metric and neighbor selection mechanism are introduced to further refine classification decisions. Experimental results underscore the effectiveness of the refined approach in mitigating genre overlap issues, significantly enhancing classification accuracy for rock and country genres. This study contributes to the advancement of music genre classification techniques, offering an innovative solution for handling overlapping genres and demonstrating the potential of KNN-MFCC synergy in achieving accurate and refined genre classification.
