Identifikasi Tumbuhan Penghasil Polen dari Madu Lebah Tanpa Sengat di Belitung: Identification of Plants as Pollen Source in Honey of Stingless Bee Heterotrigona itama and Tetragonula laeviceps from Belitung
Stingless bees forage to the flower for nectar and at the same time, pollen also trapped in the body hairs of the bees. Mostly pollen was concentrated into the pollen basket and transferred to the pollen and honey pot in the stingless bee nest. Pollen is male gametophytes of seed plants which have various of shapes, sizes, and ornamentations. This palynology study was aimed to identify the plants of pollen source that were found in honey of stingless bee Heterotrigona itama and Tetragonula laeviceps in Belitung and to analyze characteristics of the pollen. Pollen was extracted from honey and conducted the acetolysis and identification of the pollen in honey. We found 11 and 19 plant species as pollen soirce in the honey of H. itama and T. laeviceps, respectively. Pollen from Macaranga tanarius (23.72%) and Cocos nucifera (22.53%) were the two most dominant species on the H. itama honey. Pollen from Ageratum conyzoides (16.36%) are most often found in T. laeviceps honey. The most common pollen in honey of H. itama and T. laeviceps were from Arecaceae with a total of three species. Pollen from plants with tree habitus is most commonly found in honey of both species of stingless bees
Perilaku Alami dan Tidak Alami Burung Kakatua Jambul Kuning (Cacatua sp.) di Animal Sanctuary Trust Indonesia, Jawa Barat: Natural and Stereotype Behavior of Yellow-Crested Cockatoo (Cacatua sp.) in Animal Sanctuary Trust Indonesia, West Java
Cockatoo (Cacatua sp.) is one of birds that is widely distributed in Indonesia and often kept as pet, thus threatening the Cacatua population in the wild. Environmental condition may affect the behavior of Cockatoo. Some unnatural behavior may arise due to living in the captive. Different cage conditions may result in different behavior performance in Cockatoo. Research on daily behavior at animal rescue sites at ASTI Bogor has never been conducted. This study aimed to analyze natural and stereotype behavior of Cacatua sp. at animal rescue center due to foreclosure, and analyze the relationship between cage condition and environmental factors. This study used focal instantaneous sampling, using eight individuals Cacatua sp. Cacatua sp. in ASTI performed natural behavior more than unnatural behavior, therefore ASTI can be a good place for animal rescue. The dominant natural behaviors were Resting (Re), Preening (Pr), Feeding (Fe), Locomotion (Lo), and Fighting (Fg), while unnatural behaviors were play, bite, abnormal vocalization, feather picking and aggressive. There are no difference in behavior between male and female, and also behavior in the morning and afternoon (p>0.05), but cage condition had a significant effect to daily behavior of Cacatua sp. (<0.05)

Stingless bees have been considered as the excellent option in the apiary sector as they produce valuable products such as honey, bee pollen and wax. Apiary business with stingless bee at its core has shown progressive increment especially in West Sumatra. Therefore, to maximize the production of the stingless bee apiary, knowing detrimental predator or pest organisms as well as the way of managing them are essential. This article described potential predators and pests of stingless bee identified through rapid observation conducted on 14 April 2019 at a community apiary in Padang Pariaman Regency, West Sumatra. There were 17 predators and pests identified, consist of six bird species, five odonate species and six ant species. The predation, competition and disadvantage possibly emerge from the existence of these organisms around stingless bee apiary are discussed, along with the feasible mitigation effort
Perilaku Pemilihan Makanan dan Pengenalan Anggota Koloni pada Semut Rangrang Oecophylla smaragdina: Food Preference and Nestmate Recognition of Weaver Ants Oecophylla smaragdina
Weaver ants Oecophylla smaragdina are social insects that recognize nestmates using pheromone. This study analyzes the feeding behavior and nestmate recognition of weaver ants in the urban area of three different islands (Sumatra: Baturaja; Java: Banyuwangi; Papua: Sorong). The free ants were placed in the arena composed of chicken meat, sugar, bananas as the baits. Ten trapped ants were also located in the arena to explore the nestmate recognition between the free and the trapped ants. Five types of behaviors, i.e., approach, stalking, communication, competition, and agonistic, were recorded in 6 days. Food preferences were indicated by the number of conduct towards the feeding sites, and nestmate recognition was indicated by approaching the trapped nestmate. The results showed that the percentage of the approach behavior of free ants was the highest in the three islands but had no significant difference between Sumatra and Java and between Java and Sorong (p-value >0.05). However, the study showed significant differences for the other four behaviors observed. As predicted, the percentage of chicken meat foraged by the ants was the highest due to the carnivorous behavior. The free ants showed the nestmate recognition to the trapped ants in all behavior, except competition.
 
Aplikasi Lactobacillus plantarum NHC6 dalam Jus Nanas: Application Lactobacillus plantarum NHC6 as a Probiotic in Pineapple Juice
Probiotics are living microorganisms if consumed in sufficient quantities can be beneficial for health. One of the potential bacteria as probiotics is Lactobacillus plantarum NHC6 is a lactic acid bacteria isolated from pineapple juice. This study aimed to test the ability of L. plantarum NHC6 as a probiotic in pineapple juice. Probiotics were stored until four weeks under 4°C and 10°C which weekly is monitored data on the amount of microbes, pH, percentage of lactic acid, and total dissolved solids in fermented pineapple juice. The result shows, the shelf time for pineapple juice under 4°C has a lower microbial reduction time rather than the juice storage under 10°C. Probiotics shelf time predicted for 4°C storage was 28.32 weeks and for 10°C storage was 8.67 weeks after production. The changes in physical properties (pH, percentage of lactic acid, and total soluble solids) in 10°C storage is much faster than that off in 4°C, this happens because there is still metabolic activity by bacteria at that temperature
