Abstract

Evaluation of land suitability is carried out to perceive the potential and limitation factors of an area as an agricultural development area. Air Putih Village is one of the potential area for watermelon development area. This research was conducted to perceive the level of actual and potential land suitability for watermelon cultivation in Air Putih Village, Tuah Madani District, Pekanbaru City in the form of a semi-detailed map scale of 1:25.000. The method used in this study was a purposive sampling survey based on a map of land units. There were 7 units of land covering an area of 330.56 ha with a total of 21 sample points. Data were sourced from field observation, analysis of chemistry and physics of soil samples at the laboratory and secondary data from climate data. Land suitability assessment was carried out using the limiting factor matching method. The actual land suitability was in class S3 and N with effective soil depth (rc), base saturation (nr), slope (eh) and soil texture (rc) as limiting factors. The class of the potential land suitability for watermelon cultivation were S2, S3 and N.

Abstract

Masyarakat Nagari VIII Koto yang berlokasi di Kecamatan Payakumbuh, Kabupaten Lima Puluh Kota, bergantung pada hasil pertanian sebagai sumber penghasilan utama, terutama dengan budidaya jahe. Jahe yang dikembangkan kelompok Restu ibu yaitu jenis jahe gajah. Hasil panen yang tidak maksimal akibat serangan organisme pengganggu tanaman (OPT) menjadi hambatan utama bagi petani. Untuk mengatasi hal ini, penggunaan rizobakteri pemacu pertumbuhan tanaman atau Plant Growth Promoting Rhizobacteria (PGPR) sebagai agen hayati diperlukan untuk meningkatkan produksi jahe. Tujuan kegiatan pemberdayaan kelompok tani ini untuk memberikan pemahaman kepada kelompok tani mengenai manfaat rizobakteri sebagai agen hayati, yang dapat memacu pertumbuhan dan peningkatan produksi jahe. Metode kegiatan ini menerapkan pendekatan praktis melalui sosialisasi, penyuluhan, dan demonstrasi penanaman langsung yang melibatkan partisipasi aktif kelompok tani. Hasil yang diperoleh yaitu kelompok tani memperoleh pemahaman mengenai manfaat rizobakteri sebagai agen hayati untuk memacu pertumbuhan dan hasil. Mereka juga mampu mengidentifikasi organisme pengganggu tanaman (OPT) dan mengetahui cara pengendalian yang efektif.

Program ini bertujuan untuk memberdayakan masyarakat dalam mengoptimalkan pengelolaan sumber daya yang tersedia, sehingga mereka mampu mengambil keputusan dan tindakan yang mendukung kesejahteraan desa secara berkelanjutan. Dengan memanfaatkan potensi lokal seperti Ubi Manggalo, program ini berfokus pada peningkatan kemampuan masyarakat dalam menggali dan mengembangkan potensi desa yang selama ini belum dimaksimalkan. Melalui pendekatan partisipatif, program ini mendorong partisipasi aktif masyarakat dalam setiap tahap kegiatan, sehingga tidak hanya meningkatkan kemandirian, tetapi juga membangun kapasitas dan keterampilan dalam pengelolaan sumber daya lokal secara berkesinambungan. Hasil dari program ini menunjukkan peningkatan kemandirian masyarakat serta adanya keinginan yang kuat untuk memanfaatkan potensi lokal, yang diiringi dengan peningkatan keterampilan dan kapasitas masyarakat dalam mengelola potensi desa dengan lebih efektif dan berkelanjutan.

Abstract

The oil palm ecosystem is one of the suitable habitats for the order Dermaptera. Several physical factors, especially humidity in the oil palm ecosystem, support these insects' existence. In the oil palm ecosystem, Dermaptera has several functions, including as a predator of oil palm pests, but on the other hand, these insects also prey on Elaeidobius kamerunicus Faust, the primary pollinator of oil palm plants. For that reason, research was conducted to study the structure of the Dermaptera community in the ecosystem of oil palm plantations in the Sitiung sub-district. This research was a survey conducted at three locations- Sitiung, Gunung Medan, and Sungai Duo Villages—the collection of insect samples by hand collection. Identification of insect samples was carried out at the species level according to Burr (1910) and Borror et al. (1996). In this study, 214 individuals of the order Dermaptera were found to consist of three species: Cheslisoches mario, Forficula auricularia, and Vostox brunneipennis. C. mario was the dominant Dermaptera species found with an Importance Value Index (IVI) was 1.27. Based on this research, it is known that the community structure of the order Dermaptera was simple because it has low diversity values.

Abstract

Fire caterpillars (Sethotosea asigna, Lepidoptera: Limacodidae) are a major pest of oil palms and cause harvesting losses. Natural enemies such as Sycanus sp. are reported to control fire caterpillars. The biological of Sycanus sp. were observed in the laboratory when fed using the alternative feed, maggot Black Soldier Fly (Hermetia illucens L.). Variables observed were egg, nymph, imago stadia, and the life cycle of Sycanus sp. The data were calculated, displayed as figures and tables, and given descriptive analysis. The results showed that predatory insects, Sycanus sp., can thrive well by providing alternative feed, such as Black Soldier Fly (BSF) (Hermetia illucens) maggots. Based on the results, it was known that one female Sycanussp. Could produce 101 eggs after being fed BSF maggots, with an incubation period of 17 days. The duration of the nymph stage was around 64.16 days, with a relatively low mortality rate (2-12%). Morphologically, Sycanus sp. grew and developed well. The body length was about twice the width of the body. The age of the male was shorter than that of the female, as was the body size. The sex ratio also showed fewer males than females (2:3).
