Abstract

Ultraviolet-B (UV-B) light is known to induce plant resistance in suppressing disease infection. Its ability to induce plant resistance has been widely used as an inducer of plant resistance. This study aims to determine the ability of UV-B light in suppressing shallot twisted disease, potency of plant resistance induction through accumulation of peroxidase enzymes, salicylic acid, chlorophyl content and to observe shallot growth after treatment. This study applied UV-B light with a duration of 65 mW/m2 for 4 hours each day for 3, 5 and 7 days, for inoculated and non-inoculated plants. Fungicide (Benomyl) was used as a comparison for inoculated plants. The results showed that UV-B irradiation of 4 hours/day for 7 days was able to reduce the incidence of shallot twisted disease, but the incubation period among treatments was not significantly different. UV-B irradiation of 4 hours/day, for 7 days was able to increase salicylic acid content, and maintain the same chlorophyll content as the negative control, however the peroxidase enzyme content was not significantly different. Treatment of UV-B 4 hours/day for 7 days irradiation did not inhibit the growth and production of shallot plants.

Abstract

Root and basal stem rot disease caused by Xylaria sp. is a new diseases in Indonesian sugarcane plantation. The disease has been reported only occurred in sugarcane plantations in Sumatera. Limited information about the disease has slowed down disease diagnosis in the field. The research was aimed to describe symptoms, signs, and spatial distribution of the disease caused by Xylaria. A survey was conducted at a sugarcane plantation in South Sumatera (3° 26’ 16.6” S dan 104°40’ 09.8” E). Typical symptoms of the disease involved drying of all leaves and plant death, dry rot of root and basal stem, and retarded growth of ratoon cane were recorded. Stroma was found on surface of diseased stems and on soil surface of diseased plants, and spatial aggregation of diseased plants was observed in all locations. The distribution of the diseased plant aggregately and the presence of stroma on diseased plants are important characteristics of the disease diagnosis in sugarcane plantations.

Abstract

Maize downy mildew, caused by Peronosclerospora spp., is a major disease affecting maize cultivation in tropical regions, particularly in Indonesia. One potential control strategy is the induction of plant resistance. Previous studies have demonstrated that benzoic acid (BA), a non-fungicidal chemical compound, can induce maize resistance against downy mildew. Induced resistance mechanisms do not directly inhibit pathogen development but enhance the plant’s defensive response to infection. This study utilized various maize lines, ranging from susceptible to resistant, to evaluate the impact of BA-induced resistance on photosynthesis rate and chlorophyll content as the key agronomic parameters associated with the plant growth. The results showed that BA treatment did not significantly increase the photosynthetic rate and chlorophyll content in moderately resistant and resistant maize lines. However, in susceptible and moderately susceptible lines, BA treatment enhanced both parameters, indicating its role in strengthening plant resistance. These findings suggest that resistant maize lines do not respond to BA induction, whereas susceptible and moderately susceptible lines benefit significantly from its application. This provides new insight that BA can potentially induce resistance in susceptible maize plants against downy mildew.

Abstract

Gagal jantung menjadi masalah kesehatan yang progresif dengan angka mortalitas dan morbiditas yang tinggi di negara maju maupun negara berkembang. Tingginya angka readmission juga menyebabkan tingginya biaya perawatan yang harus dikeluarkan, oleh karena itu diperlukan pendekatan penanganan yang baik dengan meningkatkan efektifitas perawatan diri di rumah. Penelitian ini bertujuan untuk mengeksplorasi pemahaman yang mendalam tentang pengalaman, kebutuhan dan harapan pasien gagal jantung dalam melaksanakan perawatan dirinya (self care) di rumah. Penelitian ini menggunakan desain penelitian deskriptif kualitatif dengan pendekatan fenomenologi. Pemilihan partisipan diambil dengan cara purposive sampling sebanyak delapan orang. Pengumpulan data dilakukan dengan wawancara mendalam dengan membuat pertanyaan berdasarkan tujuan yang ingin dicapai. Data yang diperoleh dianalisis dengan menggunakan langkah-langkah Colaizzi sehingga dapat disimpulkan tema-tema sesuai pengalaman partisipan. Dari hasil analisa data ditemukan dua belas tema utama yaitu : (1) pengetahuan gagal jantung (2) Tanda dan gejala yang dialami (3) respon terhadap penyakit (4) mengatur pola makan (5) mengkonsumsi obat (6) olah raga dan aktifitas (7) kontrol ke dokter (8) hambatan yang dihadapi (9) dukungan keluarga (10) dukungan informasi (11) sumber informasi (12) harapan pasien. Melalui penelitian ini, kebutuhan pasien, kesulitan yang dihadapi serta harapan terhadap perawatan dirinya dapat teridentifikasi dengan jelas. Pasien gagal jantung yang melakukan perawatan diri di rumah membutuhkan dukungan keluarga serta dukungan informasi untuk dapat menjalankan program pengobatan dengan baik. Melalui penelitian ini dapat direkomendasikan untuk disusun media edukasi dan informasi yang dapat memudahkan pasien gagal jantung dalam melakukan perawatan dirinya di rumah sehingga harapan pasien untuk dapat ditangani dengan baik dapat terlaksana.
