Abstract

ECO-FRIENDLY PEST MANAGEMENT İN TANJUNG SELOR REGİON. Pest control in the most parts of the Republic of Indonesia still relies on the application of synthetic chemical insecticides, including the Tanjung Selor area. Tanjung Selor is the administrative center or capital of the province of North Kalimantan. This sub-district located in Bulungan Regency, North Kalimantan Province, Indonesia with the majority of the population working as farmers. The unwise use of synthetic chemical insecticides by farmers has a negative impact on many aspects. Therefore, it is necessary to socialize about environmentally friendly pest control. This activity begins with a preliminary survey in order to determine the respondents and the efficiency of the implementation of the next activity. After that, the activities were socialization and ended with an evaluation to determine the effect of the activities. The activities have a positive influence on the knowledge and actions of farmers on environmentally friendly pest control. Prior to the activity, only 27% of farmers knew about it and 10% carried out environmentally friendly pest control. However, three months after the activity, these two figures increased to 40% and 15%.

Abstract

Keberadaan gulma dipengaruhi oleh jenis pupuk yang diberikan pada tanaman budidaya. Setiap jenis pupuk memiliki kandungan yang berbeda sehingga berpengaruh terhadap spesies gulma yang tumbuh. Agar dapat mengetahui spesies gulma yang tumbuh perlu dilakukan identifikasi pada lahan budidaya. Penelitian dilakukan bulan Juni – Agustus 2021 di Kebun pertanian Kelompok Tani Sinar Harapan, Kota Tarakan Provinsi Kalimantan Utara. Metode penelitian yaitu metode sampling acak. Parameter digunakan yaitu nama gulma dan jumlah gulma. Hasil analisis vegetasi gulma di lahan sawi kemudian diolah untuk menghitung kerapatan, frekuensi, INP dan SDR. Dalam membandingkan keragaman gulma sebelum dan setelah diberikan pupuk limbah udang maka dihitung Indeks Kemerataan Evenness Indeks kekayaan Margalef, Indeks Keanekaragaman Shanon-Wiener, dan Indeks Kekayaan jenis Sorensen. Hasil penelitian menunjukan bahwa gulma yang terdapat sebelum diberikan pupuk limbah udang di tanaman sawi yang mendominasi yaitu spesies Cyperus iria nilai SDR sebesar 30,33%. Gulma ditemukan di tanaman sawi setelah diberikan pupuk limbah udang yang mendominasi yaitu gulma Cyperus iria nilai SDR sebesar 21,71%. Indeks Kekayaan Jenis Margalef sebelum dan sesudah diberikan pupuk limbah udang termasuk kategori sedang. Indeks Keanekaragaman Shannon-Wiener sebelum dan sesudah diberikan pupuk limbah udang kategori sedang. Indeks Kesamaan Jenis Sorensen dengan nilai 81,82%. Indeks Kemerataan Evennes sebelum diberikan pupuk limbah udang yaitu 0.62 dan setelah diberikan pupuk limbah udang yaitu 0.64.

Abstract

Triggered by a fungus of the genus Fusarium, wilting prevails in various horticultural crops in Indonesia. In asparagus beans, this pathogen can lead to decreased production. One eco-friendly controlling measure is the application of botanical pesticides made from betel leaves and neem leaves which have been extensively used to control various pathogenic fungi.  This study aims to evaluate the effectiveness of plant-based pesticides made from neem and betel leaves in controlling Fusarium wilt in asparagus beans. This research was run for approximately six months, initiated at the Laboratory of Plant Protection in Universitas Borneo Tarakan, and ended in the Experimental Garden of the Faculty of Agriculture. It involved Fusarium propagation, preparation of planting media, planting asparagus beans, infecting Fusarium, and producing as well as applying botanical pesticides. It employed a one-factor randomized block design with 5 treatments, control (P0), 5% neem leaf extract per plant (P1), 10% neem leaf extract per plant (P2), 5% betel leaf extract per plant (P3) and 10% betel leaf extract per plant (P4). The covariance analysis results showed that the treatment did nothave a significant effect on the number of affected branches, the number of pods and pod weight. Even so, it can be concluded that P2 can reduce wilted branches by up to 48%, with the same concentration, and P4 can reduce wilted branches by up to 52%. In terms of the total number and the total weight of the pods, P4 achieved the best results with 77 pods, weighing 3,272 grams.
