There is a high diversity of bees in the tropics, including honey bees and stingless bees, which are the main sources for honey and other ecosystem services. In Indonesia, beekeeping practices have been developed for centuries, and they have been part of many cultural practices in many traditional communities. The objective of this research was to study the beekeeping status and managed bee diversity in Indonesia and to investigate beekeepers’ perspectives on the factors and obstacles related to beekeeping. Direct interview and online interview were conducted to gain data on bees and beekeepers. In total, 272 beekeepers were interviewed across 25 provinces. Samplings of honey bees and stingless bees were also done during direct interviews for further identification and, when possible, pollen identification. All data and specimens were then sent to IPB Bogor for compilation and identification. We recorded 22 species of bees, including 3 species of honey bees and 19 species of stingless bees, that are reared by Indonesian beekeepers, with Apis cerana and Tetragonula laeviceps as the most common species. Our research also found that the majority of beekeepers fall into the category of the younger generation (30–39 years old) with educational background mostly from senior high school. Based on the beekeepers’ perspectives, there are several obstacles to beekeeping, especially the occurrence of death of bee foragers attributed to climate, food source, and pesticides. In conclusion, there is a need to develop a strategy for beekeeping and bee conservation in Indonesia, especially for adaptation and mitigation from environmental changes with a particular focus on climate and land-use change.

Biology of the spotted barb Barbodes binotatus (Valenciennes, 1842) in Barambai River, east Kalimantan is unknown. This study aimed to analyses sizes of fish, sex ratio, length-weight relationship and condition factor of the spotted barb. A total of 347 fish samples were collected by several gears in Barambai River from August to October 2017. The results of this research showed that the total length of the fish ranged from 45.67 to 146.01 mm and weight ranged from 1.27-43.34 g. The sex ratio of male and female were 1:1.12. The length-weight equations for males was W = 1x10-5 L3.063, W = 8x10-6L3.108 for females, and W = 9 x 10-6 L3.091 for both sexes. The condition factor (K) for the spotted barb was ranged between 0.826 – 2.214 with mean value of 1.163.  AbstrakBiologi ikan wader bintik dua Barbodes binotatus (Valenciennes, 1842) di Sungai Barambai, Kalimantan Timur belum diketahui.

Biology of bonylip barb (Osteochilus vittatus Valenciennes, 1842) in Benanga Reservoir, East Kalimantan is not yet known. The purpose of this study was to analyze distribution of the length and body weight of fishes, sex ratio, gonad maturity level, length-body weight relationship, and condition factor. In total 278 fishes samples were collected during the five months, from January to May 2019 with a purposive sampling method at Benanga Reservoir, and gill net with  mesh size 0.5; 1; and 1.5  inches used. The results of this research showed that the total length of the fishes analyzed ranged from 72.21–196.57 mm and body weight ranged from 5.12–89.21 g. The sex ratio of male and female were 1:2.02. The male and female fishes were dominated by mature gonad. The length-body weight relationship models calculated for the total fishes sample was W=1x10-5L2.967 (r=0.988) for males, W=5x10-6L3.199 (r=0.989) for females and W=7x10-6L3.126 (r=0.987) for both sexes. Isometric growth patterns (b=3) were observed in males, meanwhile positive allometric growth patterns (b>3) were observed in females and both sexes. Calculation of the condition factor (K) resulted in 1.181±0.117 for males, 0.949±0.094 for females, and 1.026±0.150 for all specimens. The condition factors of bonylip barb from the Benanga Reservoir inside the range recommended as suitable for freshwater fish species in the tropical regions.

One of the diseases often threatens the health of free-range chickens and egg-laying chickens are worm parasites (endoparasites). Parasites can be transmitted through food, drinks and the cage environment. Sanitation is one of the preventive steps carry out by farmers to protect livestock against infection from the environment. The objective of study was to determine the prevalence and intensity of parasitic worm eggs that infect the digestive tracts of free-range chickens and egg- laying hens in Muara Badak District. Research was done by observing worm eggs in fecal samples. A total of 60 samples consisting of 30 samples of egg-laying hens in Tanjung Village and 30 samples of free-range chickens in Badak Baru Village, Muara Badak. For the sample analysis technique used 2 methods are namely the floating method and the sedimentation method. The results has showed the type of worm eggs are infected the digestive tract found in free-range chickens and egg-laying chickens had consisted of Echinostoma revolutum, Raillietina echinobothrida, Raillietina tetragona, Davainea proglotina, Amoebotaenia sphenoides, Ascaridia galli, Capillaria annulata and Trichostrongylus tenuis. The highest prevalence in free- range chickens and egg-laying chickens were found in Ascaridia galli was 53.33% and 40%. While the lowest prevalence in free-range chickens against Raillietina echinobothrida and Amoebotaenia sphenoides 3.33%. egg-laying chickens are against Echinostoma revolutum, Raillietina tetragona and Trichostrongylus tenuis 6.67%. The highest intensity in free-range chickens and against Ascaridia galli was 141 eggs/individual and in egg-laying chickens was 139 eggs/individuals. The lowest intensity in this research was found in free-range chickens against Amoebotaenia sphenoides and Raillietina echinobothrida 3 eggs/individuals and egg-laying chickens against Echinostoma revolutum 5 eggs/individuals. Keywords: Endoparasites, Prevalence, Intensity, Chicken, hen.
