Abstract

Lactic acid bacteria are included in the gram positive bacteria that are widely distributed in the digestive tract of living things, such as in the feces of the Pandan Luwak (P. hermaphroditus) and important role in improving the microbial balance in the body. The purpose of this study was to obtain phenotypic characters, types of bacteria and similarity relationship between lactic acid bacteria from feces of Pandan Civet (P. hermaphroditus) in West Kalimantan and lactic acid bacteria in the identification book Bergey's manual of determinative bacteriology. This research was conducted by the method of isolation and screening bacteria using MRSA media supplemented with CaCO3 1%. Characterization of lactic acid bacteria based on morphological, biochemical, and physiological characters in Bergey's Manual of Determination Bacteriology. The results of the analysis using the MVSP (Multivariant Statistic Package) program with SSM coefficients and the UPGMA method obtained 44 bacterial isolates  thought to belong to two genera, namely the genus Lactobacillus and Bifidobacterium with three species, namely L. casei, L. brevis and B. bifidum. The results of the analysis showed that 12 bacterial isolates had a similarity index of 87,6% to L. casei, 17 bacterial isolates had a similarity index of 92,2% to B. bifidum and 15 bacterial isolates had a similarity index of 84,5% to L. brevis.

Abstract

Kelulut (Hymenoptera: Meliponini) is a honey-producing bee and belongs to the eusocial bee group. Kelulut is also a pollinating insect that is widespread in the world, including Indonesia. The study of kelulut diversity can describe the composition of kelulut in an area and the condition of an ecosystem. This study aimed to obtain data and information on kelulut diversity in three different forest areas (primary forest, secondary forest, and ecosystem restoration area). The study was conducted by capturing kelulut using sugar solution bait traps and free sampling. The results obtained were analyzed using the Shannon-Wiener Diversity Index (H'), the Evenness index (E) and the Simpson Dominance Index (C). A total of 747 individuals from 12 types of kelulut were found in this study. The secondary forest gets the highest H' value (1.869), followed by the primary forest (1.672) and ecosystem restoration area (1.159). The diversity of stingless bees is higher in forested areas due to environmental factors such as temperatures within the normal range (25.5-28.9°C), the availability of trees for nesting, and the abundance of food sources from flowers.
