Abstract

Plants can listen to sounds and respond to these sounds by changing metabolic activity. A good sound will have a positive effect on plant metabolism and vice versa. The adhan to prayer is a call to pray and contains good sentences. This study aims to determine the effect of the sound of the adhan on the growth, production, and disease incidence of the Brassicaceae family. This was conducted by performing split plot design which consisted of 2 factors namely plants spesies and the sound of the adhan. The plant species consisted of 3 treatment levels, namely: A1= Mustard greens, A2= Kailan, A3= Pakcoy. Meanwhile, frequency of the adhan consists of 7 levels, namely: B0= without adhan, B1= 2 times a day, B2= 3 times a day, B3= 4 times a day, B4= 5 times a day, and B5= 6 times a day. The results showed that there was a tendency for differences in plant height, leaf area, plant total fresh weight and net weight given the sound of the adhan compared to without sound, but statistically it was not significantly different. The more often the plant is played the sound of the adhan can increase the production of the brassicaceae family.

Abstract

This study aims to analyze the comparison of the development of leaf spot disease (Cercospora capsici) in red chili plants (Capsicum annuum L.) in highland and lowland areas during the rainy season. Leaf spot disease is a serious problem that hinders proper growth in chili plants. The research was conducted in December 2022 using a descriptive survey method, focusing on the issue of leaf spot disease in chili plants in farmers' fields. The results showed that the average percentage of symptomatic chili plants affected by leaf spot disease in the highland area was 50.89%, while in the lowland area, it was 29.77%. The average level of leaf spot disease incidence in the highland was 26.79%, whereas in the lowland, it was 24.61%. From these findings, it can be concluded that leaf spot disease (Cercospora capsici) has a higher incidence rate in red chili plants in the highland compared to the lowland during the rainy season. Knowledge of this difference can assist farmers in taking appropriate preventive or intervention measures to address disease outbreaks in red chili plants in both regions.

Abstract

Cabai merah memiliki peran penting dalam budaya kuliner dan industri pertanian di Indonesia. Namun, serangan patogen seperti penyakit busuk buah dapat menghambat produksi. Penelitian ini menggunakan metode survey dengan pengambilan sampel secara purposive random sampling untuk mengkaji tingkat serangan penyakit busuk buah (Colletotrichum capsici) pada tanaman cabai merah (Capsicum annuum L.) di dua lokasi yang berbeda, yaitu dataran tinggi dan dataran rendah. Hasil penelitian menunjukkan bahwa terdapat variasi tingkat serangan penyakit busuk buah pada sampel tanaman cabai merah di dataran tinggi dan dataran rendah. Rata-rata persentase serangan penyakit  didataran tinggi pada kelima sampel adalah 33.38%, dengan persentase serangan tertinggi pada Sampel 5 mencapai 58.63%. Sedangkan rata-rata persentase serangan penyakit didataran rendah mencapai 65.168%, dengan persentase serangan tertinggi pada Sampel 5 mencapai 80.99%. Hal ini mengindikasikan tingkat kerentanan yang lebih tinggi terhadap penyakit busuk buah pada sampel tersebut. Tingkat serangan yang tinggi berdampak negatif pada produksi cabai merah di dataran rendah, mengurangi kualitas dan kuantitas hasil panen. Kesimpulannya, hasil penelitian ini menunjukkan bahwa tingkat serangan penyakit busuk buah pada tanaman cabai merah bervariasi antara dataran tinggi dan dataran rendah. Oleh karena itu, diperlukan upaya pengendalian, seperti pengelolaan sanitasi dan pemilihan varietas tahan penyakit, untuk meminimalkan serangan penyakit dan mendukung produksi cabai merah.
