Abstract

Iles-iles are often referred to as porang or yellow iles or Amorphophallus muelleri blume. The plant is potentially for agro-forestry development and their tubers are used as a functional food, and raw materials of various types of industries. The plant is expected to increase income and welfare of forest communities. The forest around ancient volcano Nglanggeran Gunungkidul has potency as a tourist attraction. The forest is situated at an altitude 400 M asl, with an area of approximately 30 Ha. Tourism potential will increase with the presence of agro-forestry iles-iles. Increased potency is expected to provide added value to the local community in particular and the district government of Gunungkidul in general. In addition, it is hoped that a variety of benefits that have been mentioned, will not decimate the forest as a source of oxygen that contributed as the lungs of the world. This information is expected to be useful for researches and government of Gunungkidul in increasing community’s income, developing agro-forestry, conserving forest, and developing tourism. Key words: ancient volcano, forest conservation, iles-iles, income, tourism

Abstract

One of strategic fruit commodities was avocado that had high economic value. Pest and diseases were main problems faced by farmers. This study identified diseases and pest associated with avocado plantation intercropping with mango and durian in Watulembu district, Wonogiri Regency through symptoms and its controls. The observation was done to the abnormalities avocado plants and the field condition surrounding the planting area. It was conducted by visual observation, recorded using a digital camera, and then described and identified based on their symptoms and a literature review. The results of our observation were Algal leaf spot, Anthracnose, Sooty mold, and Planococcus citri. Pest and plant disease could be controlled by cultural technique, avoid plant stress, and also using chemical pesticide.

Abstract

Metarhizium anisopliae dengan penambahan bahan organik digunakan sebagai pengendali hama uret Lepidiota stigma dan sekaligus sumber nutrisi M. anisopliae. Tujuan penelitian ini adalah untuk mengidentifikasi pengaruh penambahan berbagai macam bahan organik pada jamur M. anisopliae untuk mengendalikan hama uret L. stigma pada tanaman jahe merah. Penelitian dilakukan di Kebun Percobaan UPN “Veteran” Yogyakarta Sempu, Wedomartani, Ngemplak, Sleman, Yogyakarta yang disusun dalam Rancangan Acak Kelompok Lengkap (RAKL) 2 faktor + 1 kontrol dan diulang sebanyak 3 kali. Faktor pertama adalah dosis M. anisopliae yaitu 10 g/ 3 kg media tanam, 20 g/ 3 kg media tanam, dan 30 g/ 3 kg media tanam. Faktor yang ke dua adalah jenis bahan organik yaitu pupuk kascing, pupuk kotoran sapi dan pupuk kotoran kambing. Data dianalisis dengan menggunakan analisis sidik ragam (ANOVA) Kontras Orthogonal dengan taraf 5%, dilanjutkan dengan uji DMRT (Duncan’s Multiple Range Test) taraf 5%. Hasil penelitian menunjukkan bahwa dosis M. anisopliae 30 g/ 3 kg media tanam merupakan dosis yang paling baik dalam meningkatkan mortalitas uret, bobot segar akar dan volume akar serta menekan kerusakan akar tanaman jahe merah. Penambahan pupuk kotoran sapi dan kotoran kambing mampu meningkatkan mortalitas uret dan menekan kerusakan akar tanaman jahe merah.

Abstract

Red chili is cultivated practically everywhere and plays a crucial role in Indonesian culture, economy, and cuisine. Plant diseases have been the main factor driving the country’s yield reduction of red chili. This research was conducted to observe chili plant diseases in Hargobinangun Subdistrict, Pakem District, Sleman, Yogyakarta. Chili variety Twist-42 was planted in the area. The Twist-42 variety is a local variety that is well adapted in the middle plains between 450 – 650 masl (meters above sea level) and is a good variety in both the dry and rainy seasons. There were 360 red chili plants as samples. The diseases found are Yellow leaf curl disease, Anthracnose, Ralstonia wilt, and Root knot nematode (Meloidogyne spp.).

Abstract

Citrus Vein Phloem Degeneration (CVPD) is transmitted by the insect vector Diaphorina citri is still a major obstacle to world citrus production. Vector handling still relies on chemical insecticides which are not environmentally friendly and less effective. This study was conducted to identify the ability of dried guava leaf extract in reducing the olfactory response of D. citri. Y-tube olfactory test was conducted to identify the repellency effect of a mixture of citrus leaf extract and guava (Psidium guajava) leaf extract at various leaf ages and in various proportions to vector and its predator (Menochilus sexmaculatus). The results showed that guava leaves had a repellent effect on D. citri, but not on M. sexmaculatus. The repellant effect was higher on young guava leaves than on medium and old ones. Red guava leaves have a highest repellant effect than white guava and non-seed guava leaves. Guava leaf extract is an alternative means to control D. citri. However, the types of compounds that function as repellants need to be studied further.

Abstract

Black pepper (Piper nigrum L.) is a high-value spice crop whose productivity is strongly influenced by plant health and the microbial conditions in the rhizosphere. This study aimed to characterize the fungal communities in the rhizosphere of healthy black pepper plants grown in fields   with a history of pest and disease outbreaks, using a metagenomic approach based on ITS1 sequencing via the Illumina platform. Rhizosphere soil samples were collected from healthy black pepper plants in a plantation located in Tribuana Village, Banjarnegara, Central Java, which had experienced pest and disease incidences in the previous growing season. Taxonomic composition, relative abundance, and diversity indices (Shannon, Simpson, and Richness) were analyzed. The results revealed that the fungal community was dominated by organic matter- decomposing fungi (57.29%), followed by plant growth- promoting fungi (PGPF) at 19.82%. These two groups not only exhibited quantitative dominance but also showed high diversity and evenness values, indicating ecological stability within the root system of healthy pepper plants. These findings highlight the importance of cultivation practices that support the persistence of functional microbial communities, such as organic matter amendments and the application of biofertilizers. In conclusion, the high dominance and diversity of decomposer fungi and PGPF in the rhizosphere of healthy black pepper plants underscore their critical role in maintaining plant health and provide a scientific basis for sustainable soil management strategies. Pathogenic fungal communities accounted for 12.76% of the total abundance, exhibiting moderate diversity and relatively high evenness.
