Abstract

The attack of Phytophthora spp. caused the descrease of apple crops production up to 90 %. Some antagonist mold species are able to inhibit the growth of Phytophthora pathogens onapple crops. The objectives of this research were to identifify and to study the potency of antagonist mold for inhibite the growth of Phytophthora spp. pathogens on apple crops. The Phytophthora spp. were isolated using baiting method with apple fruit  while antagonist molds were isolated by dilution method from soil sample of apple plantation. The inhibition assay of antagonist molds against Phytophthora was carried out by dual culture method. The isolated both of Phytophthora spp. and antagonist mold isolates were identified based on phenotype characters. The research result showed six molds namely Trichoderma sp.1, Trichoderma sp.4, Trichoderma sp.6, Aspergillus sp.2, Aspergillus sp.3 and Penicillium sp.1 which were antagonist on the Phytophthora pathogens onapple crops. Among the antagonist mold species, Trichoderma sp.6 had the highest inhibitory potency (62.95 %) while Penicillium sp.1 had the lowest inhibitory potency (28.82 %) against the growth of Phytophthora.

Abstract

Citrus is a popular horticultural crop planted in different areas in Indonesia. The needs for fruits increases every year, yet production cannot fulfill market demand. One of the contraints are the red scale pest attacks Aonidiella aurantii (Maskel). The implemeintation of standard operating procedure (SOP) in citrus cultural practices is expected to have effects on the population and intensity of red scale attacks. The research was carried out from January to August 2020 on farmer's orchards located at the center of citrus production in Batu, East Java, Indonesia. This experimental study used the research design theory method. The plots were devided into 2 conditions; first, the plots applied SOP, such as regular pruning, sanitation, and organic fertilizer application. While, the second was the conventional plots representing the common farmer maintenance, farmer of not pruning and cleaning weeds throughout the garden, and using NKP inorganic fertilizer. Every evaluated plot covered 1,500 m2, and 10 plants were systematically sampled from every plot. The parameters included numbers of attacked fruits, the abundance of natural enemies and attack intensity of A. aurantii that were taken from the cardinal directions. The results of the study showed that the implementation of SOP was able to significantly reduce population density and intensity of A. aurantii pest attacks and was able to increase the abundance of natural enemies and the quality of citrus fruit when compared to conventional citrus cultivation methods.

Abstract

Tungau merah ( Panonychus citri McGregor) adalah salah satu hama tanaman yang menyerang daun jeruk. Biasanya, petani mengendalikan hama menggunakan pestisida kimia dan menyebabkan kerusakan lingkungan karena racun yang terkandung dalam bahan pestisida. Pestisida kimia juga menghasilkan peningkatan resistensi hama terhadap pestisida. Pestisida persisten juga meninggalkan residu yang sulit dibersihkan pada tanaman sehingga pestisida alami diperlukan sebagai alternatif pestisida kimia. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi pestisida nabati daun sirsak ( Annona muricata ), daun pepaya ( Carica papaya ), Krisanmembuat kematian hama merah dan pestisida nabati tetap ada. Hasil penelitian menunjukkan bahwa konsentrasi pestisida 5% menghasilkan 100% mortalitas fase imago dan instar fase 1 pada 48 jam pengamatan. Angka kematian tertinggi adalah perlakuan pestisida daun pepaya konsentrasi 5% pada fase imago yaitu sejumlah 29,67

Abstract

Hama dan penyakit tanaman apel merupakan permasalahan serius yang selalu dihadapi oleh para petani apel. Serangan hama dan penyakit tersebut berpotensi untuk membuat tanaman apel menjadi mati sehingga berdampak pada hasil panen apel petani yang tidak makasimal. Serangan hama dan penyakit pada tanaman apel tersebut dapat teratasi dengan cepat apabila petani mampu mengidentifikasi jenis hama dan penyakit berdasarkan gejala-gejala yang muncul. Kesulitan petani apel adalah tidak mengetahui dengan cepat jenis hama dan penyakit yang menyerang tanaman apel. Solusi yang tepat untuk menangani masalah tersebut dengan membangun sistem pakar yang dapat mendiagnosis hama atau penyakit yang menyerang. Pada penelitian ini ditawarkan solusi deteksi penyakit dan hama tanaman apel menggunakan metode forward chaining dan metode penelusuran depth first search. Hasil yang diperoleh tingkat adaalah tingakat akurasi diagnosis antara sistem dan pakar mencapai 100%.
