Abstract

Nursamsi I, Partasasmita R, Cundaningsih N, Ramadhani HS. 2018. Modeling the predicted suitable habitat distribution of Javan hawk-eagle Nisaetus bartelsi in the Java Island, Indonesia. Biodiversitas 19: 1539-1551. Javan hawk-eagle (Nisaetus bartelsi) is an endemic raptor of Java Island. The conservation status of Javan hawk-eagle (JHE) according to IUCN is endangered (EN) and included in CITES Appendix II list, and this species is also protected by the Indonesian government law based on act no. 5, year 1990. The position of Javan hawk-eagle as a top predator is now very threatened by habitat fragmentation, wildlife trade, and the declining quality of its habitat. The primary purpose of this study was to give preliminary information about the distribution of predicted suitable habitat for JHE as a means of finding potential releasing sites, as an evaluation for habitat protection, and even as an option for the development of new JHE protected areas. However, mapping the spatial distribution of potential habitat for JHE using terrestrial survey is problematic because it requires enormous time, fund, and human resources. The most possible approach is by using Ecological Niche Modeling (ENM)/species distribution modeling (SDM). In this study, modeling exercise was conducted by using a maximum entropy method as an adaptation from Maxent software ver. 3.4.1, with the utilization of JHE-nest coordinate data and 16 environmental variables datasets as the main input. The predicted suitable habitat distribution map has shown a good match with historical and present records of JHE and has fairly succeeded in capturing a wide range of habitat patches from tiny spots to quite large suitable habitat. Modeling results also showed that altitude, annual mean temperature, and two types of land cover (closed shrub, and forest area) are considered to be most important variables affecting the distribution of potential habitat for JHE. Moreover, about 17.77% (23,209 km2) area of Java Island has been projected to be suitable for Havan Hawk-Eagle's habitat, which mostly spread in mountainous areas while also appear in several lowland areas. This study suggests the importance of topographic, climatic, and land cover as pivotal predictors in determining the suitability of habitat for JHE. This study also shows that the modeling results have a good match with the historical records of JHE across the island, which suggests the overall accuracy of the model.

Abstract

Authors. 2018. Genetic variability, heritability, correlation, and path analysis in tomato (Solanum lycopersicum) under shading condition. Biodiversitas 19: 1527-1531. Information on genetic variability, heritability and character association between quantitative characters with yield are crucial in crop improvement. Eighteen genotypes of tomato were evaluated to study the quantitative genetic of yield and various yield attributing character under shading condition at Pasir Kuda Station, Bogor Agriculture University, West Java, Indonesia from August 2016 until January 2017. The result showed that plant height, dichotomous height, fruit weight, fruit length, fruit diameter, number of fruit per plant, and the fruit set had broad genetic variability and high heritability. Characters with broad genetic variability and high heritability can be used as sources in shading tolerance tomato improvement. Fruit weight and fruit number per plant had significant positive correlation coefficient and direct positive effect on fruit yield per plant. It is, therefore, recommended that fruit weight and fruit of number per plant should be given due importance in selection to develop shading tolerance variety in tomato

Abstract. Kahirun, Sabaruddin L, Mukhtar, Kilowasid LOMH. 2019. Evaluation of land use impact on river water quality using macroinvertebrates as bioindicator in Lahumoko Watershed, Buton Island, Indonesia. Biodiversitas 20: 1658-1670. The Lahumoko Watershed, a small watershed, that empties into the sea is sensitive to water quality changes due to land use changes by humans. Uncontrolled land use changes can threaten the sustainability of the river ecological functions of the watershed. It is important to examine the comparison of river water quality in locations that represent land uses. So, the objectives of this study were to reveal the impact of land use on biological water quality in rivers and to analyze the relationship between macroinvertebrates communities with parameters of biodiversity and physicochemical at the observation locations that represented land use. Biological samplings were done using a hand net with a hole size of 0.5 mm mesh, at five stations, each with three replications, with a length of 30 m of each replication, 60 minutes per station. The results of the study showed that individual abundance, family biotic index and diversity index parameters indicated that the water quality was quite good in the upstream watershed (LM1, LM2, and LM3 stations) and somewhat worse in the middle (LM4 station) and downstream of the watershed (LM5 station). The Spearman's correlation, Dendrogram, and Canonical Correspondent Analysis (CCA) showed that there were similarities among LM1, LM2 and LM3 stations, and also between LM4 and LM5 stations. Physicochemical parameters, especially the velocity and flow rate of the river flow had significant correlation with individual richness and density.

Biodiversitas 20: 1524-1536. Based on data from various environmental studies at the Upper Cisokan Pumped Storage (UCPS) Hydropower plan area, further studies need to be carried out that can provide clearer guidance on how to protect and restore the environment (including habitat) around the UCPS, protect, and manage the endangered biodiversity through adaptive approaches and ecosystem management. One of these studies was the UCPS Biodiversity Management Plan (BMP). The aim of this study was to identify the strategy for biodiversity management at the project site. Methods of this study were based on several years of qualitative and descriptive-analytical studies, which updated information from earlier studies. Information on the area’s biodiversity was obtained directly through field surveys and indirectly through semi-structured interviews and focus group discussions (FGD) with local community members and other stakeholders in the area. This article presents the strategy for biodiversity management at project site, including minimizing habitat gap and habitat loss; expanding and enriching habitats; making corridors; protecting the natural forests (protection of remnant forest); controlling access; managing fire, the impact of traffic on native fauna, land clearing and human-wildlife conflict; minimizing impacts to biodiversity,  particularly threatened species; integrating management with adjoining land managers (PLN, perhutani, the community); strengthening capacities for integrating and institutionalizing biodiversity conservation and management; conducting campaign for biodiversity awareness, communication, and education; and developing value-added products and alternative sustainable livelihood for bio-resource-dependent communities.

Abstract

Hastuti ED, Hastuti RB, Darmanti S. 2018. Plankton and benthos similarity indices as indicators of the impact of mangroveplantation on the environmental quality of silvofishery ponds. Biodiversitas 19: 1558-1567. This research was carried out in a coastalarea of Semarang City, Central Java, Indonesia. It aimed to study the composition of plankton and benthos communities in silvofisheryponds, and to analyze the similarity in plankton and benthos composition between ponds as an indicator of variation in pondenvironmental quality. Nine pond treatments were sampled for their plankton and benthos composition. The nine treatments consisted ofa factorial combination of three mangrove species assemblages (Avicennia marina (M1), Rhizophora mucronata (M2), and a mixture ofboth (M3)) at three mangrove populations (5 trees (S1), 10 trees (S2), and 15 trees (S3)). Similarity index analysis was conducted tomeasure the impact of treatments on the plankton and benthos communities. The total number of plankton species identified inobservation periods in May, July and September of 2016, were 23, 16 and 21 species repectively, while for the benthos there were eightsomewhat different species identified in each of the three observation periods. Fluctuation in plankton and benthos composition tendedto achieve a balance in richness by the time of the the third observation period. Diatoms, particularly Gyrosigma sp., were the mostwidely distributed plankton in the first and third observation periods, while Pyramidella sulcata was the only well-distributed benthosspecies in the three observation periods. Pairwise similarity indices between treatments ranged from 0% to 62.5% for plankton and from16.7% to 100% for benthos. The results of the investigation suggested that mangrove species affected plankton and benthos speciesrichness in this initial stage of a silvofishery development: plankton composition appeared to be richer in ponds with A. marina, whilebenthos was richer in ponds with R. mucronata.

Abstract. Triandiza T, Zamani NP, Madduppa H, Hernawan UE. 2019. Distribution and abundance of the giant clams (Cardiidae: Bivalvia) on Kei Islands, Maluku, Indonesia. Biodiversitas 20: 884-892. Giant clams, ecologically important bivalves in coral reefs, are under anthropogenic pressures in most parts of their range, necessitating the study of population status for conservation management. Here, we assessed species composition, distribution, size density, and habitat condition of giant clams in Kei Islands. A total of 9 reefs around the islands (Dar 1, Dar 2, Pulau Kur, Pulau Tanimbar Kei, Pulau Adranan, Pulau Dullah Laut, Difur, Labetawi, dan Ohoidertoom), were surveyed using quadrat-transect line in September-December 2017. We found five species of giant clams, i.e., Tridacna crocea, T. maxima, T. squamosa, T. noae, and Hippopus hippopus. Of these species, we report a new record for T. noae which was previously not known to be present in the region. The overall density was recorded at 0.0428 individual/m2. Juveniles clams were fewer than the adults clam, this may indicate that the survival rate of recruit is low. Most individuals were found living on dead coral algae substrate (75 %). Based on the findings, this study suggests that giant clam population in Kei Islands are imperiled, indicated by low population density and local extinction for species T. gigas and T. derasa. It is recommended to establish a protected area and restocking of giant clams by through implementing sasi laut (traditional law) with a minimum period of 5 years.

Abstract. Hastuti YP, Rusmana I, Nirmala K, Affandi R, Tridesianti S. 2019. Identification and characterization of nitrifying bacteria in mud crab (Scylla serrata) recirculation aquaculture system by 16S rRNA sequencing. Biodiversitas 20: 1339-1343. Recirculation is one of the systems used for increasing aquaculture production, for example, is mud crab Scylla serrata culture. Aquaculture activities will produce organic nitrogen waste and can be affected to inorganic condition (nitrification bacteria). Nitrifying bacteria are capable of changing aerobically from NH4+ to NO2-(nitrite) and from NO2-to NO3-(nitrate). This current work aimed to identify and characterize nitrifying bacteria in mud crab (S. serrata) culture with a recirculated system. Nitrifying bacteria were isolated using serial dilution (10-1 until 10-5) of open filter FB water sample previously cultured in a specific medium. Bacterial identification was performed using a procedure of PrestoTM Mini gDNA Kit (Geneid) for DNA extraction and Polymerase Chain Reaction (PCR) primer 63F and 1387R for 16S rRNA gene amplification. Molecular identification using 16S rRNA sequences, the nitrifying bacteria isolated from mud crab recirculation aquaculture system were 99% identified as a group Pantoea calida, Pseudomonas stutzerii dan Halomonas sp. Morphological characterization of the colony morphology showed that a mucoid appearance and appeared cream in color and large size. Furthermore, their cells were recognized as basil and Gram-negative.

Shiferaw M, Asmare B, Tegegne F, Molla D. 2018. Farmers perception and utilization status of improved forages grown in the natural resource areas of northwestern Ethiopia. Biodiversitas 19: 1568-1578. A study on the perception and utilization of improved forages grown in natural resource conservation areas was conducted in selected districts of northwestern Ethiopia. This study aims to investigate the perception of improved forage production and utilization system on natural resource conservation areas in selected areas of northwestern Ethiopia. Primary data was collected from selected households by interviewing using semi-structured questionnaire. Field observation and focus group discussion were also employed to enhance the survey data. A total of 180 households (90 from each district) were selected and interviewed. The collected data were analyzed with descriptive statistics using SPSS software version 20. The result indicated that the average land and livestock holding of respondents were 2.24 ha and 5.56 TLU per household, respectively. The most common forage production methods used by the smallholder farmers were broadcasting (41%), cutting (28%) and row seedling (18%) for both districts. For the majority of respondents (44%), the purpose of forage production of respondents was for animal fodder. Farmers in the study areas had a good perception about improved forage production as forages due have multifunction to the household in the form of soil conservation, fodder production, and income generation. Though improved forages have many roles in the livelihood and environmental management of the study districts, respondents had problems of skill in production and utilization of forages. This study elucidates that, relevant development and research interventions such as management and utilization of improved forage production should be the future direction of research and development. Sustainable forage development and use for nature conservation and is becoming very important to be a livestock feed source if cut and carry system is regularly applied.

Abstract

Seran YN, Sudarto, Hakim L, Arisoesilaningsih E. 2018. Sandalwood (Santalum album) growth and farming success strengthen its natural conservation in the Timor Island, Indonesia. Biodiversitas 19: 1586-1592. Sandalwood (Santalum album L.) is a unique plant of the East Nusa Tenggara (NTT) Province of Indonesia and locally known as the unity symbol woody fragrance (hau meni). The study aimed to compare growth quality of trees grown in plantations and forests in the districts of North Central Timor (TTU) and South Central Timor (TTS). Vegetation analysis was held by purposive sampling in eight sites comprising 87 plots. Plots sizes were 20x20 m2 for trees, 10x10 m2 for poles, and 5x5 m2 for saplings. Variables observed in each plot included density, trunk diameter, height, crown quality, and vitality. Data were analyzed by descriptive and multivariate statistics. The results showed that the growth of sandalwoods varied spatially in all study sites and was classified into five groups. Two plantations in TTS District showed better trees growth quality compared to those in TTU. Higher saplings and poles density were found in two sites, a plantation and a forest in TTU plantation, and in a forest in TTS. However higher vitality were found in two plantations, each one in TTS and TTU. Inferior growth was observed in Nununamat plantation. Farmers had a significant role in strengthening sandalwood conservation in two districts as shown by their successful farming and trees growth quality that was similar to those in the forests.
