Abstract

This study discusses the use of keyboard drums at the Karo ethnic youth work party in Mardingding Village, Mardinding District, Karo Regency. This study uses descriptive qualitative research. The results of the study indicate that the use of keyboard drums is currently used in almost every Karo ethnic activity or traditional ceremony, because the keyboard is a digital musical instrument with a music program (style) that can produce sounds like the Karo ethnic traditional instrument, the five sendalanen drum. The functions contained in this year's work party are the function of music as an aesthetic appreciation, the function of music as entertainment, the function of music as an emotional expression, the function of music as a means of communication, the function of music as a physical reaction, the function of music as related to social norms, the function of music as a sustainable contribution, the function of music as social integration. This event was held to unite residents in Mardingding District, Tanjung Pamah Village, Bandar Purba Village, and Lau Solu Village

Abstract

Kompetisi gulma merupakan salah satu faktor pembatas utama dalam pertumbuhan tanaman kelapa sawit, terutama pada fase awal perkembangan. Gulma alang-alang (Imperata cylindrica) diketahui memiliki daya kompetisi tinggi serta menghasilkan senyawa alelopati yang dapat menghambat pertumbuhan tanaman utama. Penelitian ini bertujuan untuk menganalisis respon fisiologis kelapa sawit terhadap kompetisi gulma Imperata cylindrica melalui pendekatan studi literatur. Metode yang digunakan adalah kajian pustaka terhadap berbagai sumber ilmiah yang relevan, meliputi jurnal nasional dan internasional, dengan analisis deskriptif terhadap data sekunder. Parameter yang dikaji meliputi biomassa tanaman, kandungan hara, dan pertumbuhan vegetatif kelapa sawit berdasarkan hasil penelitian terdahulu. Hasil kajian menunjukkan bahwa keberadaan Imperata cylindrica menyebabkan penurunan biomassa tanaman akibat kompetisi dalam penyerapan air, cahaya, dan unsur hara. Kandungan hara dalam jaringan tanaman, khususnya nitrogen dan kalium, juga mengalami penurunan yang berdampak pada terganggunya proses fisiologis. Selain itu, pertumbuhan vegetatif seperti tinggi tanaman dan jumlah daun menunjukkan penurunan pada kondisi terinfestasi gulma. Efek alelopati yang dihasilkan alang-alang turut memperparah tekanan terhadap tanaman kelapa sawit. Kesimpulannya, Imperata cylindrica memberikan dampak negatif terhadap respon fisiologis kelapa sawit melalui mekanisme kompetisi dan alelopati, sehingga diperlukan strategi pengendalian gulma yang efektif untuk mendukung pertumbuhan optimal tanaman.
