Abstract. Husodo T, Wulandari I, Saputri Y, Kasmara H, Hermawan W, Kusmoro J, Shanida SS, Khairina F, Haydar MRA, Asyraf MN, Febrian RR. 2024. Blooming calendar and polliniferous plants in Djuanda Great Forest Park, West Java, Indonesia: Implication for beekeeping management. Biodiversitas 25: 3216-3229. Information was unavailable regarding the types of pollinator plants and their blooming periods in Djuanda Great Forest Park, West Java, Indonesia. Information about flower blooming seasons was useful for various purposes. These findings will provide a basis for understanding the importance of Apis cerana Fabricius, 1793 in plant pollination and plant species resources for honey bees so that beekeeping practices can be carried out sustainably. The blossoming period of a plant is determined by its blooming period at the time of observation. The blooming period is observed every month in the second and fourth weeks for six months (December 2021-May 2022). Pollen collection was carried out in August 2021 (dry season). Pollen identification was carried out using the acetolysis method, which involves dissolving the non-pollen components of a sample to reveal the pollen grains, thereby enabling accurate identification. An overview of the observation records revealed the presence of 249 plant species from 82 families. The Asteraceae family has the most abundant species richness. Most plants were identified as pollinator plants (30.52%), nectariferous plants (10.04%), and plants that produce both (18.47%). Flowering plants of melliferous plants for honeybees are available throughout the rest of the year, especially from December to May. Therefore, to optimize honey harvesting, it is important to establish multiple colonies during periods of large honey flows. Honeybees may use alternative sugar sources beekeepers provide, such as fruit juice, during nectar scarcity. We would like to know more about the year-round bloom calendar. Sharing knowledge with farmers about the availability of melliferous plants in certain months will empower them to make decisions for sustainable beekeeping.

Abstract. Atsaury ZIA, Husodo T, Megantara EN, Lastini T, Hernawan E, Wulandari I, Shanida SS. 2025. Population and habitat analysis of Javan gibbon (Hylobates moloch) in fragmented forests of West Java, Indonesia. Biodiversitas 26: 2857-2872. Javan gibbons (Hylobates moloch) face various anthropogenic disturbances that are intensive enough to damage and even eliminate their habitat. Additionally, previous studies have primarily focused on protected areas. However, there is limited information on the Javan gibbon in non-conserved areas, such as Ciletuh Geopark, Cisokan, Cijedil, and Kanaan, West Java, Indonesia. The study objective was to determine the distribution and habitat of Javan gibbon in non-conservation areas in West Java. Line transect distance sampling and quarter methods were used in this study. Despite the high level of anthropogenic disturbance, Cisokan exhibited the highest density of Javan gibbon individuals and groups, with 19.48 individuals per square kilometer and 7.79 groups per square kilometer. Generally, the habitat of Javan gibbons is dominated by food plants, such as kondang (Ficus variegata), puspa (Schima wallichii), and beunying (Ficus fistulosa). Hence, 97 plant species were identified as food plants of Javan gibbons, while 84 were eaten by their fruits, 25 by their leaves, and 12 by both. Javan gibbons tend to live in forests with closed and interconnected canopies, as well as on slopes and hilltops with a slope greater than 40% at altitudes ranging from 115 to 1,564 meters above sea level (m asl). Establishing ecological corridors to enhance habitat connectivity in degraded vegetation is crucial for conserving Javan gibbon populations.
