TL;DR: The maggot showed good ability to degrade organic waste; indicated by the nutrient content of the larvae, which contributes 45-50% and 24-30% for protein and fat respectively, the fish used in this study gained weight 300 to 400 g within five months.
Abstract: Fahmi MR. 2015. Optimization of bioconversion by using mini larvae Hermetia illucens to address aquafeeds shortage. Pros Sem Nas Masy Biodiv Indon 1 (1): 139-144. The bioconversion is a natural process consisting of extracting nutrient residue from byproducts being converted into biomass of insect larvae. This is a new source of animal proteins and fats for aquaculture. The insect in the bioconversion process (Hermetia illucens, F. Stratiomyidae, O. Diptera) or Black Soldier Fly (BSF) is well known as the best biodegradation agents. The study consisted of three steps, (i) investigating the biology and life-cycle of H. illucens to collect its minilarvae (maggot), (ii) bioconversion of organic wastes such Palm Kernel Meal (PKM) using maggot, and (iii) the use of maggot as a basic source for feeding Red Gouramy (Osphronemus gouramy) (±60 g). The eggs of H. illucens hatched within 3 to 6 days, the larvae stage spent 3 to 4 weeks, the pre-pupae leave feeding site to drier place, the pupae reached adult’s stage in about 1 weeks and the adults longevity ranged from 1 to 2 weeks. The maggot showed good ability to degrade organic waste; indicated by the nutrient content of the larvae, which contributes 45-50% and 24-30% for protein and fat respectively. The fish used in this study gained weight 300 to 400 g within five months.

TL;DR: Ismaini et al. as mentioned in this paper determined the vegetation structure and composition and inventory of plant species in the Mount Dempo protected forest, using analysis of vegetation methods on sample plots 10x10 m2 for trees and 2x2m2 for seedlings with total 16 plots observation.
Abstract: Ismaini L, Lailati M, Rustandi, Sunandar D. 2015. Composition and plant diversity on Mount Dempo, South Sumatra. Pros Sem Nas Masy Biodiv Indon 1: 1397-1402. Mount Dempo is a protected forest area located on the Barisan mountain chain of Sumatra. This mount is the highest mountain which located in South Sumatra on altitude 3159 meters above sea level. Sustainability of protected forest function is determined by the existence of vegetation, and need to management effort based on the analysis of vegetation. The purpose of this research was to determine the vegetation structure and composition and inventory of plant species in the Mount Dempo protected forest, using analysis of vegetation methods on sample plots 10x10 m2 for trees and 2x2 m2 for seedlings with total 16 plots observation. The results of the vegetation inventory tree level were found 21 species with a total of 119 individuals and at the level of seedling was found 98 species with a total of 830 individuals. The results of the analysis vegetation showed Cassia sp. and Camellia sinensis dominate tree level with the Importance Value Index 83.83% and 77% respectively, while for the seedlings was dominated by Strobilanthes hamiltoniana and Strophacanthus membranifolium with IVI of 12.20% and 10.46%. Index diversity of Shannon-Wiener (H ') was 1.9394 for trees and 3.697 for seedlings showed the diversity of medium and high; Index of species richness (Dmg) was 4.1849 for trees and 14.4315 for seedlings showed moderate and high richness; and Index of Evenness (E) was 0.6370 for trees and 0.8063 for seedlings showed high evenness.

TL;DR: The conclusion is the quality of sperm X better than Y sperm quality and non-sexing sperm is better than both sperm Y and sperm X before thawing.
Abstract: Putri RDA, Gunawan M, Kaiin EM. 2015. Evaluation of quality sperm sexing Friesian Holstein(FH) post thawing. Pros Sem Nas Masy Biodiv Indon 1: 2057-2061. Factors that influence the success in artificial insemination (AI) is the quality of the sperm to be inseminated. Frozen sperm storage was done to extend the life of sperm. However, there are any impacts caused by the freezing sperm process. The qualities of sperm are still fresh and will vary on the quality of sperm after thawing. The aim of this study is to determine the quality of FH bull sperm sexing after thawing. Parameters used are the percentage of motility, plasma membrane intact, viability, abnormalities, and morphometry. Sperm motility was analyzed by SpermVision. Abnormalities, morphometry, and viability were analyzed using Eosin-Negrosin and Hoechst dye, and parameters for plasma membrane intact using the three different formulations of Hypo Osmotic Swelling (HOS) Test. The results showed that the highest sperm motility was Sperm X (52.39%). The highest plasma membrane intact was Sperm X (80.95%) and the highest viability was Sperm Y (80.16%). Low sperm abnormality was observed in nonsexing (5. 4%). The conclusion is the quality of sperm X better than Y sperm quality and non-sexing sperm.

TL;DR: Handayani et al. as mentioned in this paper assessed the diversity of medicinal plant species used by the people in this area through interviews with 30 respondents and found that Staurogyne elongata was the most potential plant as a drug.
Abstract: Handayani A. 2015. Utilization of medicinal plants by people around Gunung Simpang Nature Reserve, West Java, Jawa Barat. Pros Sem Nas Masy Biodiv Indon 1: 1425-1432. Gunung Simpang Nature Reserve is one of the conservation areas in West Java. Information on the use of plants as medicine by surrounding people needs to be collected. The study was conducted in February 2010, in Miduana hamlet, Balegede Village, Naringgul District, Cianjur, West Java, to assess the diversity of medicinal plant species used by the people in this area. The information was collected through interviews with 30 respondents. The results showed there were 74 species of plants from 40 families that commonly used for treatment. Among these species Staurogyne elongata was the most potential plant as a drug.

TL;DR: This study aims to determine the diversity of dragonfly and damselfly (Odonata) in some water springs of Panekan sub- District, Magetan, East Java, with the assumption that the water source provides less pollutant.
Abstract: Pamungkas DW, Ridwan M. 2015. Diversity of dragonfly and damselfly (Odonata) in some water springs in Magetan, East Java. Pros Sem Nas Masy Biodiv Indon 1: 1295-1301. Dragonfly is an insect that plays an important role in the balance of the ecosystem, acting as predators. Most of Odonata’s life is in the water in form of larvae. Dragonfly occupies some specific habitat types of waters. This study aims to determine the diversity of dragonfly and damselfly (Odonata) in some water springs of Panekan sub- District, Magetan, East Java, with the assumption that the water source provides less pollutant. Expected specific species of dragonflies that occupy the habitat. The used method was the descriptive method by means of direct collection using insect nets to be identified. Collection sample used active exploration around the water spring to the vegetation formation. Based on the results, 19 species of Odonata was found including 10 species of (Anisoptera) and 9 species of damselflies (Zygoptera). Diversity index (H') of Odonata obtained 2,28 and relative abundance (KR) species Orthetrum sabina was the highest (29.4%), while the lowest was Orthetrum pruinosum (0.3%). Odonata including aggregated distribution, except for Diplacodes trivialis and Orthetrum pruinosum that had regular distribution.
