Abstract

Munia birds (Lonchura spp.) are pests that attack paddy plants during the reproductive phase. The traditional methods of controlling birds are considered less effective because birds can adapt to the tools used. This study aimed to determine the effectiveness of a metallic light-based bird-repellent prototype to reduce paddy yield loss. The experiment was conducted in Cileles Village paddy fields, Jatinangor Subdistrict, Sumedang Regency, West Java Province, Indonesia. The effectivity of the prototype was tested by measuring the effective distance (m2), counting the frequency of bird visits (number of visits), bird populations, and the level of paddy damage (%), and paddy yield (kg/64 m2). The result of the experiment showed that 3 m was an effectual deterrent factor for the prototype, thus the tool can protect paddy plants with an area of 28.26 m2. The frequency of bird arrivals in the treatment was 22.25 times, compared to 61.25 times in the control; the bird population in the treatment was 48.25 birds, while the control was 108.75 birds; the level of damage to paddy panicles in the treatment was 10.11%, compared to 37.79% in the control; and the production of paddy yield with the repellent was higher (33.37 kg/64 m2) than the control (23.09 kg/64 m2). This innovative prototype was potentially able to deter bird pests in the paddy fields.

Abstract

Buah sukun (Artocarpus altilis) merupakan komoditas lokal yang potensial namun belum dimanfaatkan secara optimal oleh masyarakat Desa Rancaekek Wetan. Rendahnya nilai jual dan kurangnya inovasi dalam pengolahan menyebabkan petani sulit memperoleh keuntungan. Tujuan dari kegiatan pengabdian ini adalah meningkatkan kapasitas masyarakat dalam mengolah sukun menjadi produk bernilai ekonomis melalui pelatihan dan sosialisasi berbasis pengalaman. Kegiatan dilaksanakan dalam rangka Orientasi Kehidupan Kampus (OKK) Universitas Padjadjaran dengan metode pendekatan experiential learning dan manajemen partisipatif. Sebanyak 21 warga desa mengikuti kegiatan sosialisasi, praktik, dan pengisian kuesioner evaluasi sebelum dan sesudah kegiatan. Hasil menunjukkan adanya peningkatan dengan tingkat pengetahuan pasca kegiatan yang tercermin dari wawasan ketahanan pangan (57,14%), pengenalan terhadap buah sukun (95,24%), dan pemahaman pengolahan sukun (90,48%). Namun, mayoritas besar peserta (85,71%) menyatakan belum memiliki rencana produksi secara konkret yang menunjukkan perlunya dukungan lanjutan agar hasil pelatihan dapat diimplementasikan.. Kegiatan ini membuktikan bahwa pendekatan edukasi langsung dapat mendorong peningkatan kapasitas masyarakat terkait pengolahan sukun. Oleh karena itu, program pendampingan lanjutan diperlukan untuk mendorong penerapan hasil pelatihan dan keberlanjutan usaha olahan sukun di tingkat rumah tangga.

Abstract

Spodoptera frugiperda Smith is a major pest of corn plants. Information on the life cycle and survival of this pest is important for proper and effective control. This study was conducted to determine the life cycle and survival of S. frugiperda in several areas in West Java. This study was conducted from June to August 2020. Samples were taken from several areas divided into three categories: highlands in Lembang District (1,100 m asl), middlelands in Jatinangor District (858 m asl), and the lowlands in Tarikolot District (103 m asl). Sampling used the observation method to study the effect of differences in altitude on population, life cycle, and survival. The results showed that there was no significant difference in the development time of S. frugiperda among the three different areas. The average development time of S. fugiperda was 24.55 days (highlands), 24.36 days (middlelands), and 24.07 days (lowlands). The survival percentage of S. frugiperda from highland, middle, and lowland areas in the egg phase was 95.44%, 97.34%, and 96.89%, larval phase 98.46%, 98.65%, and 98.48%, and pupal phase 87.63%, 88.08%, and 93.43%. The sex ratio of S. frugiperda from the highlands was 1:1, from the middlelands was 1:1.28, and from the lowlands was 1:0.89. Location did not affect the width parameter of the head capsule in S. frugiperda. Based on the test results, it is known that the life cycle, survival, and sex ratio of S. frugiperda from several regions do not have significant differences.
