Abstract

Ketergantungan yang tinggi terhadap pupuk dan pestisida sintetis, apalagi di tengah pademi Covid-19, menyebabkan banyak petani di Desa Tulo tinggal pasrah dan tak mengurus lahannya, bahkan banyak beralih mencari pekerjaan lain di luar sektor pertanian. Permasalahannya adalah masyarakat di Desa tersebut, khususnya kelompok tani Siaga belum memanfaatkan dengan baik limbah pertanian yang cukup banyak tersedia di Desa Tulo menjadi pupuk organik disebabkan rendahnya keterampilan mitra dalam mengolah potensi lokal tersebut. Dengan demikian tujuan kegiatan kegiatan Pengabdian Kepada Masyarakat (PKM) ini adalah untuk memberikan pemahaman dan keterampilan kepada petani dalam memanfaatkan limbah pertanian menjadi pupuk yang bernilai ekonomi dengan penambahan Trichoderma sebagai bioaktivator. Di tengah Pandemi Covid-19 petani juga diberikan pendidikan dan penyuluhan tentang protokol penanganan kesehatan Covid-19. Metode pendekatan yang dilakukan dalam kegiatan PKM ini adalah berupa pelatihan dan bimbingan teknis serta pembuatan demplot untuk meningkatkan keterampilan membuat pupuk organik serta pembuatan formulasi Trichoderma. Hasil evaluasi menunjukkan terjadi peningkatan pengetahuan, keterampilan dan kegiatan ini mendapat respon yang baik, terbukti dengan keaktifan mitra dalam mengikuti seluruh kegiatan PKM ini.

Abstract

This study aims to determine the relationship of social domographic factors with the behavior of farmers in applying pesticides to shallots in Sigi Biromaru District, Sigi Regency. This research uses quantitative methods using univariate analysis for frequency distribution and bivariate analysis (chi square) to determine the correlation between variables. Both use Statistical Product and Service Solutions (SPSS) 20.0. Determination of the location of the study was conducted purposively based on previous observations. The area is a center of shallot and horticulture plants in Sigi Regency, namely; Oloboju Village and Bulupountu Village, Sigi Biromaru District. The results of the study concluded that the use of pesticides by shallot farmers was over intensity with the reason for maximum production results. Unwise behavior of farmers in controlling pests and diseases with the high use of pesticides in the field, shows that there is no relationship between age, education, experience and Integrated Pest controlling (IPC) training with the behavior of shallot farmers in applying pesticides.

Abstract

Biodiversity is an important part of the agricultural ecosystem (agroecosystem) and diversity is determined by the environment and the application of pesticides in the field. Research on the diversity of arthropods in shallot cultivation with different intensities of pesticide application aims to determine the types and populations of arthropods in shallot cultivation on land with different intensities of pesticide application. The research was conducted in the village of Soulowe, which is the center of shallot plants in Sigi Regency, with a massive and intensive application of pesticides, from December 2019 to March 2020. Sampling was carried out using absolute methods (direct observation) and relative methods (Pitffal Traf and Jaring Ayun). The results of the identification carried out in the Unisa and Untad Palu laboratories found that the diversity of arthropods in low-intensity areas of pesticide application was more than that of medium and high applications. There are 7 orders and 13 families, namely Oxyopidae, Grillotalpidae (Ordo Araneae), Scarabaeidae, Coccinellidae (Order Coleoptera), Forficuloidea (Order Dermaptera), Agromyzidae, Muscidae (Order Diptera), Formicidae, Apidae (Order of Hymenoptera), Noctuidae (Order of Hymenoptera) and Acrididae, Gryllidae andTotigonidae (Order Orthoptera). The level of diversity, evenness and family wealth as well as the abundance of arthropod individuals were higher in land with low pesticide application intensity than medium and high pesticide application.

Abstract

Excessive use of pesticides confers several ecological and environmental consequences. In this research, we evaluated arthropod occurrence on shallot crops in Palu Valley, Central Sulawesi as an impact of pesticide application in different frequencies. Almost all farmers used synthetic pesticides for controlling pests and diseases where 46.7%, 43.3%, 10.0% of them applied in high, moderate, and low frequency, respectively. By comparing to the last application, the first reduced arthropod diversity index, evenness index, and abundance by 13.8%, 6.7%, and 70.6%, while the second by 7.3%, 2.3%, and 33.5%, respectively. Analysis of the dynamic abundance of pests and natural enemies in seven weeks observation indicated that the pests abundance at low and moderate levels was no different. Whereas predator abundance at low frequency was significantly different with moderate and high rate and between the last two not distinct and the presence of parasitoids was not observed at all, it means the natural enemies were susceptible to pesticides. These data showed the negative impact of pesticides application to arthropods including pests resistance and natural enemies lost; therefore it is necessary to minimize the use of pesticides and integrated pests.
