Abstract

Produktivitas tanaman mentimun di Indonesia umumnya masih rendah, salah satu penyebabnya adalah kondisi tanah yang keras akibat pemupukan anorganik yang terus, menerus. Bunga jantan pada mentimum juga banyak sehingga jumlah buah yang dihasilkan sedikit. Untuk meningkatkan pertumbuhan dan hasil tanaman mentimun dapat dilakukan dengan pemberian pupuk organik kotoran kambing yang dapat memperbaiki sifat fisik kimia dan biologi tanah serta zat pengatur tumbuh (ZPT) paclobutrazol yang dapat meningkatkan jumlah bunga betina. Penelitian untuk mendapatkan dosis kotoran kambing dan konsentrasi ZPT paclobutrazol yang tepat dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Jember, menggunakan rancangan acak kelompok (RAK) faktorial terdiri dari 2 faktor. Faktor pertama yaitu dosis pupuk kotoran kambing terdiri dari: 0, 10, 20 dan 30 ton/ha. Faktor kedua konsentrasi paclobutrazol terdiri dari : 0; 0,250 ; 0,375 dan 0,500 ml/l, dengan 3 ulangan. Parameter pertumbuhan dan hasil tanaman di analisis dengan analisis varian dan uji t dengan tingkat kepercayaan 95 %, apabila berbeda nyata di uji dengan uji jarak berganda Duncan dengan α,5 %. Hasil penelitian membuktikan bahwa dosis pupuk kotoran kambing 10 - 30 ton/ha meningkatkan tinggi tanaman, luas daun, berat segar dan berat kering total tanaman. Pemberian Paclobutrazol 0,250 - 0,500 ml/liter menurunkan tinggi tanaman, luas daun, berat segar dan berat kering total tanaman serta jumlah bunga jantan. Konsentrasi paclobutrazol 0,375 ml/l berpengaruh terbaik pada jumlah bunga betina dan jumlah buah. Terdapat interaksi perlakuan dosis kotoran kambing dan konsentrasi ZPT Paclobutrazol terhadap bobot buah pertanaman dan potensi produksi dengan perlakuan terbaik : dosis kotoran kambing 20 hingga 30 ton/ha dan Paclobutrazol 0,375 ml/l yang menghasilkan bobot buah pertanaman sebesar : 4200,13 -4338,63 g dan potensi produksi mentimun sebesar : 138,61-143,14 ton/ha.

Abstract

The black ant (Dolichoderus thoracicus) is known as a natural enemy of Hypothenemus hampei Ferr., the Coffee Berry Borer (CBB). The conservation efforts for this natural enemy can be carried out by using ant nest technology with artificial feed. This research explored artificial nesting and feeding methods for black ant colonies in coffee plantations in Jember District, Indonesia, to combat the CBB. Utilizing a Randomized Block Design, the study examines different nest materials and shapes, various artificial feeds, and the influence of environmental factors on ant colony growth. Cocoa leaves are the most effective nesting material, significantly increasing ant populations (11,532 individuals on average) compared to coconut leaves (4,645.83 individuals); no significant impact of nest shape on ant attraction; granulated sugar is the preferred artificial feed. A notable increase in ant populations was observed with a longer nest placement duration of four weeks. Environmental factors, especially humidity and temperature, significantly influence nests' and feed interactions. The study highlights the importance of specific nesting materials and environmental considerations in effective pest management strategies in tropical agriculture, offering a sustainable approach to enhancing coffee plantation productivity.

Abstract

This study discovered extended distribution of two woodpeckers, i.e., the Rufous Woodpecker (Micropternus brachyurus) and the Laced Woodpecker (Picus vittatus) in Meru Betiri National Park, East Java. The records of M. brachyurus were observed three times in Bandealit Resort (9 December 2021, 12 February 2022, and 20 April 2022) and once in Baban Resort on 9 September 2023. These record areas were around the first record area in secondary forest and the edge of plantations (Albizia, Cocos, and Ochroma) that also bordered the Bandealit road. The second record found a single individual foraging in Mangifera indica. The record of P. vittatus was observed once at Bandealit Resort on 11 February 2024. This species perched on Cocos nucifera, Mangifera indica, and Tectona grandis. Referring to altitude distribution, P. vittatus was only recorded at an altitude of 78 m asl., while M. brachyurus was more variable in the range of 79–651 m asl. These findings provide an essential update for the bird checklist in Meru Betiri National Park, particularly in the last 10 years ago.

Abstract

This study investigates the role of coffee agroforestry in sustaining biodiversity and ecosystem functions in Kluncing, Ijen, Indonesia. By quantifying bird, butterfly, and coffee insect diversity using the Shannon-Wiener index, it evaluates ecological dynamics and their implications for sustainable land management. Bird communities demonstrated the highest diversity (2.911), indicating ecosystem stability, while butterflies (2.481) and coffee insects (1.841) exhibited lower diversity, reflecting habitat and resource limitations. Trophic network modeling using NetworkX identified keystone species like Collocalia linchi (21.9% relative abundance) among birds and the Formicidae family (29.8% relative abundance) among coffee insects, emphasizing their critical roles in ecosystem balance. Canonical Correspondence Analysis (CCA) highlighted the influence of environmental factors on species distribution. Species such as Ariadne ariadne and Delias belisama were sensitive to humidity and temperature, while Collocalia linchi favored areas with higher light intensity. The findings underscore the importance of tailored management practices to address species-specific responses to microclimatic variations. Sustainable agroforestry management is vital for preserving biodiversity, maintaining ecosystem stability, and ensuring agricultural productivity. This study also highlights challenges posed by habitat degradation and climate change, emphasizing the need for adaptive strategies to safeguard this unique agroforestry landscape.

Abstract

In Indonesia, horticulture is a crucial part of agriculture, heavily reliant on agrochemicals. This study in East Java's Jember and Bondowoso regencies compared conventional and organic farming methods, focusing on their effects on aquatic macroinvertebrates as bioindicators. Research included sites practicing conventional horticulture (cabbage, chili) and organic rice farming. Measurements of water current, pH, conductivity, dissolved oxygen, and temperature were taken, along with macroinvertebrate sampling. Significant differences were found in pH, conductivity, and water current, but not in dissolved oxygen and temperature. Organic farming showed higher macroinvertebrate diversity and lower dominance, especially the Baetidae family. While BMWP-ASPT and EPT scores were similar across methods, organic farming rated unpolluted in biotilik scores. Hierarchical cluster analysis, PCA, and CCA revealed factors influencing the ecological impacts of farming practices. The study underscores how different agricultural methods affect macroinvertebrate diversity, highlighting their role as environmental indicators. This reflects the diverse ecological impacts of agricultural management practices.

Abstract

Bird vocalizations are crucial for communication and adaptation to environmental changes. As forests are converted to agriculture, agroforestry plays a key role in conserving biodiversity. This study examines vocal bandwidth variations in four bird species-Common Tailorbird (Orthotomus sutorius), Sooty-headed Bulbul (Pycnonotus aurigaster), Olive-backed Sunbird (Cinnyris jugularis), and Small Minivet (Pericrocotus cinnamomeus)-across three coffee agroforestry sites in Jember, Indonesia: Silo, Kluncing, and Kaliwining. The study explores how vegetation structure influences vocal adaptations using sound recordings, vegetation surveys, the Kruskal-Wallis test, and Pearson correlation analysis. Results show significant vocal bandwidth differences in Common Tailorbird and Sooty-headed Bulbul. Common Tailorbird exhibited the highest bandwidth variation in Silo (2.85 kHz), followed by Kluncing (2.30 kHz) and Kaliwining (1.10 kHz) (p<0.001). Similarly, Sooty-headed Bulbul showed significant variation, with the highest bandwidth in Silo (3.1 kHz), Kaliwining (3.5 kHz), and Kluncing (2.7 kHz) (p<0.001). However, bandwidth variation in Olive-backed Sunbird (p = 0.12) and Small Minivet (p = 0.0014) was not significant. Pearson correlation analysis indicated a strong but non-significant relationship between vegetation structure (Importance Value Index) and Sooty-headed Bulbul presence (R² = 0.8999, p = 0.059). These findings suggest that while vegetation influences some species, other factors like resource availability or human activity may also shape vocal adaptations. This study enhances understanding of bird communication in agroforestry, supporting biodiversity conservation and sustainable land management.

Abstract

The Silverleaf whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), is a destructive insect pest of important greenhouse and field crops. Several studies have shown the effectiveness of Beauveria bassiana in controlling Silverleaf whitefly.. However, a major challenge lies in the rapid evaporation of water in greenhouse crop models. Therefore, this study aimed to evaluate the effectiveness of B. bassiana against the whitefly and test its compatibility with various vegetable oils as carrier media. This research at the Agrotechnology Laboratory, Faculty of Agriculture, University of Jember, used pure isolates of B. bassiana for mass production until conidia reached 2.5 x 107 per gram. We employed a Completely Randomized Design (CRD) with factors of vegetable oil (Corn Oil, Vegetable Oil, Soybean Oil) and concentration (5%, 10%, 15%) using Ultra Low Volume (ULV) formulations. The results revealed that the addition of vegetable oils enhanced the effectiveness of B. bassiana in controlling Silverleaf whitefly, with corn oil having the most significant impact due to its high carbohydrate content that supported B. bassiana viability. Additionally, the concentration of B. bassiana formulation also influenced the rate of whitefly mortality (mycocity), with a 15% concentration yielding the best results. Whitefly nymphs infected with B. bassiana exhibited slowed activity and reduced appetite. Adding vegetable oil facilitated the formation of a protective biofilm around conidia, shielding them from UV radiation, increasing conidia viability, and supporting field application. The infection process by B. bassiana required 6 days to achieve 100% mortality. This research suggests that B. bassiana can be an effective alternative for controlling Silverleaf whiteflies, especially when used with plant-based oils as a carrier medium. This approach may help reduce reliance on chemical pesticides and address issues related to Silverleaf whitefly resistance to insecticides.

Abstract

Saat ini kendala utama dalam budidaya kakao yaitu terkait penyakit busuk buah kakao yang disebabkan oleh jamur patogen Phytophthora palmivora masih belum terselesaikan. Hal ini disebabkan kondisi perkebunan kakao yang lembab menyebabkan patogen lebih cepat berkembang dan meluas dalam waktu singkat. Hal tersebut ditambah dengan seresah kulit buah kakao yang menjadi sumber inoculum penyebaran patogen. Sejauh ini petani melakukan pengendalian dengan bantuan fungisida kimia sintetik yang mahal dan tidak ramah lingkungan. Alternatif pengendalian yang murah dan ramah lingkungan yaitu dengan memanfaatkan jamur saprofit isolat lokal dari kulit buah kakao yang dapat berperan sebagai agens hayati. Penelitian dilakukan pengujian interaksi dan dominasi sesama jamur saprofit. Tujuannya adalah untuk mengetahui kemampuan berkompetisi dan hubungan antara jamur saprofit satu dengan jamur saprofit lainnya. Berdasarkan hasil penelitian bahwa jamur saprofit diduga memiliki hubungan interaksi kompetisi, mikoparasit dan antibiosis. Sedangkan hasil dominasi terendah hingga tertinggi yaitu Trichoderma sp. 3, Aspergillus sp., Trichoderma sp. 2, Trichoderma sp. 1, Rhizopus sp., Fusidium sp., Penicillium sp., dan Candida sp. Jamur saprofit dari seresah kulit buah kakao memiliki potensi dalam mengendalikan Phytophthora palmivora.
