Defining Regenerative Zoo Exhibits: A Cross- Cultural Evaluation of Visitor Preferences to Enhance Experience and Animal Welfare through landscape-Based Design Nafar, Sholihin; Gunawan, Andi; Shibata, Shozo; Nurhayati Zoos, as part of the components of urban parks, offer significant potential for integrating sustainability and regenerative landscape principles within city environments. Although these principles have been widely applied in urban and ecological contexts, their specific application in zoo environments, particularly in balancing visitor experience, animal welfare, and enhancing urban overall livability remains underexplored. This study investigates regenerative zoo exhibit strategies by evaluating visitor preference towards landscape elements. The research was conducted through two previous case studies: Ragunan Zoo in Jakarta, Indonesia, and Kyoto City Zoo in Kyoto, Japan. Visitor preferences were assessed through surveys and visual simulations of various exhibit design models, focusing on key landscape elements such as trees, water features, shrubs, and environmental enrichment. The findings show that while naturalistic elements consistently enhance animal welfare, visitor satisfaction is often influenced by visibility and spatial openness, highlighting a potential trade-off in exhibit design. Cross-cultural analysis shows both Japanese and Indonesian preferred a naturalistic landscape setting for the visitor satisfaction and animal welfare. The most influential landscape elements that influence the naturalistic landscape setting are trees, water features, and shrubs on both case studies. However, the degree of naturalistic landscape setting tends to be higher in the Japanese case study compared to Indonesian case, which may be influenced by cultural perceptions of animals and recreational expectations. This study proposes a framework for regenerative zoo exhibit design that integrates ecological aesthetic, animal behavioral enrichment, and human-animal interaction. These findings contribute to the practical strategies for supporting both sustainable and inclusive landscape design, especially in zoological settings.

Penyakit Layu Ubi Jalar (Ipomoea batatas) di Kabupaten Kuningan: Penyebab dan Hubungannya dengan Teknik Budidaya; Sweet Potato Wilt Disease (Ipomoea batatas) in Kuningan Regency: Causal Agent and Its Relationship with Cultural Practices Imani, Affan Tegar; Widodo Sweet potatoes have great potential as an alternative food crop. However, the presence of poorly managed plant pests poses a significant threat to their cultivation. Recently, this also appeared in sweet potato areas in Kuningan Regency, West Java Province. This study aims to determine the causes of wilt disease in sweet potatoes and the effect of cultural practices on disease incidence. Data was obtained through observing symptoms in the field, calculating disease incidence and conducting interviews with farmers whose disease conditions were observed. Interviews with farmers were conducted using a structured questionnaire covering cultivation techniques, plant health problems faced, and pest and disease management practices. Meanwhile, the samples were observed using a compound microscope and a stereo microscope in the laboratory to be identified based on morphological characteristics and symptoms in the field. The field data obtained were tabulated with Microsoft Office Excel 2010 and analyzed descriptively. The observations result showed symptoms of wilting caused by the pathogen Ceratocystis fimbriata with the highest incidence of 27.4% and the lowest 0%. The diversity of insect pests was obtained by observing the land along with observing the incidence of disease. Some of sweet potato cultural practices and handling of diseased plants were related to the incidence of wilt disease. The use of cv Melati, sufficient N, P, K fertilization, and crop rotation tended to lower disease incidence. Meanwhile, plantation with intensified weeding showed higher disease incidence.

Faktor-Faktor Budi Daya dan Lingkungan yang Memengaruhi Penyakit Blas Padi di Kecamatan Cidahu, Kabupaten Sukabumi Cultural Practices and; Environmental Factors that Affecting Rice Blast Disease in Cidahu District, Sukabumi Regency Bakti, Muhammad; Istiaji, Bonjok; Widodo Blast disease is one of the most devastated plant pathogens that can cause yield loss in rice. Blast disease is caused by the fungus Pyricularia oryzae (teleomorph: Magnaporthe oryzae). This study aims to determine the cultivation techniques practiced by farmers and their relationship with the severity of blast disease in rice plants. The study was conducted using two methods, namely structured interviews with 60 respondents and direct observation of blast disease severity in the field.Obtained data was then processed using Microsoft excel 2019 and the χ2 (Chi-square) test was conducted to see the relationship between the Cultivation and Environmental Factors that Affect the Rate of Blast Disease at the α = 5% level. The highest average disease severity occurred in Babakan Pari village with a severity of 24.95% and the lowest severity in Pondok Kaso Tengah village 13.03%. Sufficient of P and K fertilization, no water stress, the use of certified seeds, and full return of straw tended to reduce blast disease severity. Meanwhile, the use of herbicides in weed management shows a higher level of disease severity compared to only mechanical methods.

Efektivitas Senyawa Humat Pada Pertumbuhan Dan Hasil Panen Okra Hijau (Abelmoschus Esculentus) Di Latosol, Bogor Indriyati, Lilik Tri Asam humat Adalah molekul-molekul organik yang berperan penting dalam memperbaiki sifat-sifat tanah, pertumbuhan tanaman, dan parameter agronimi. Sumber-sumber asam humat meliputi batu bara (coal), lignit, gambut dan bahan organik lainnya. Percobaan pengaruh senyawa humat ini dilakukan pada tanaman okra hijau (Abelmoschus esculentus) sebagai tanaman indikator pada media bahan tanah Latosol dalam pot-pot yang diletakkan di lahan terbuka. Percobaan pengaruh senyawa humat ini dilakukan dengan membandingkan pengaruh beberapa takaran senyawa humat yang dikombinasikan dengan 0%, 50%, dan 75% takaran pupuk N, P, K terhadap beberapa peubah pertumbuhan dan hasil panen buah okra. Contoh bahan tanah diambil dari hamparan lahan kering pada kedalaman 0- 20 cm, dibersihkan dari sisa-sisa akar tanaman, dan dimasukkan ke dalam tiap pot setara dengan 10 kg bobot kapasitas lapang. Tanaman indikator yang digunakan adalah tanaman Okra hijau (Abelmoschus esculentus). Perlakuan pupuk N (urea), P (SP36), dan K (KCl) dengan 100% takaran disebut sebagai perlakuan pupuk standar (NPK standar). Takaran pupuk NPK standar yang diberikan adalah setara dengan 200 kg urea/ha, 200 kg SP36/ha, dan 150 kg KCl/ha. Konsentrasi senyawa humat cair yang diberikan adalah 10 mL per liter air untuk satu kali takaran (1AH), dan aplikasi senyawa humat diberikan tiga kali pemberian selama masa pertumbuhan tanaman. Hasil percobaan menunjukkan bahwa senyawa humat, baik yang diberikan secara tunggal maupun yang dikombinasikan dengan 50% atau 75% takaran pupuk N, P, K nyata meningkatkan tinggi tanaman, jumlah daun, bobot segar tanaman, dan hasil buah okra per tanaman dibandingkan dengan Kontrol. Perlakuan kombinasi 1AH+0.5NPK dan 2AH+0.5NPK menunjukkan nilai RAE lebih dari 100% (1NPK), yaitu masing-masing sebesar 154% dan 136%.
