Abstract. Darsono, Riwidiharso E, Santoso S, Sudiana E, Yani E, Nasution EK, Aprilliana H, Chasanah T. 2020. Insect diversity in various distances to forest edge in small nature reserve: A case study of Bantarbolang Nature Reserve, Central Java, Indonesia. Biodiversitas 21: 4821-4828. A nature reserve is a conservation area with the objective of conserving the biodiversity of the flora and fauna within its boundaries. However, many nature reserves are fragmented into small extent and isolated from natural habitat, causing the so-called edge effect. This research aimed to investigate insect diversity across various distances to forest edge in small and isolated protected areas. Research was conducted in the Bantarbolang Nature Reserve, Pemalang District, Central Java, Indonesia. A survey was conducted to determine the diversity of insects, especially those from the Diptera (flies), Lepidoptera (butterfly), and Hymenoptera (bees and wasp) orders. The environmental parameters recorded were temperature, humidity, and flowering plant diversity and abundance. Line transects were laid at a length of 100 m, parallel to the forest edge at three different distance ranges from the edge: 0-50 m, 50-100 m, and 100-150 m. Species diversity was measured using the Shannon-Wiener index, evenness index, and Sorensen similarity index. Over the 4-month study period, 1713 individual insects from 63 species and from the following three orders were found: Lepidoptera (Rhopalocera; 33 species, 5 families, 932 individuals); Hymenoptera (20 species, 423 individuals) and Diptera (10 species, 7 families, 376 individuals). The highest diversity was found at the edge of the forest and the lowest at the distance of 100-150 m from the forest edge. While the study area can support a diversity of insects, especially pollinating insects, but it is unable to support the conservation of light-sensitive butterflies. The results of this study suggest that small nature reserve can support a diversity of pollinating insects, especially from the Diptera, Lepidoptera, and Hymenoptera. However, it has limited conservation potential because of the significant impact of forest edges on species composition, especially on specialist butterfly species with habitat in forest interior.

This study was conducted in Bantarbolang Nature Reserve located in Kebon Gede village, Bantarbolang sub-district, Pemalang Regency. Bantarbolang is one of the nature reserves that have the structure and composition of complex vegetation so that there is a diversity of plants which can grow in a conservation area, such as medicinal plants diversity. The objectives of this study were to know the various species of medicinal plants in the Bantarbolang nature reserve block 19-21 and to know the evenness of medicinal plants in the Bantarbolang nature reserve block 19-21. This study was conducted with survey methods and sampling using a systematic square plot. The variables observed consists of dependent variables i.e. the species of medicinal plant and independent variables include environmental factors i.e. temperature, light intensity, humidity, canopy cover, and soil pH. The parameters observed are the number of species and individual number of medicinal plants. The data were analyzed using the Important Value Index (IVI), Diversity Index (H'), Evenness Index (e) and Similarity Index (IS). The plant samples were made into voucher herbarium and stored in PUNS for future references. The results of the study showed that the diversity of medicinal plants in the Bantarbolang Nature Reserve Block 19-21 was high (H’≥0) with 48 species from the 33 families of medicinal plants. Evenness of medicinal plants in Bantarbolang nature reserve block 19-21 is low (e closer to 0). Alocasia cucullata is a dominant species of medicinal plant of a distance of 0-200 meters from the forest edge.  Keywords: Bantarbolang nature reserve, diversity, medicinal plant

Abstract The effects of cattle grazing on biodiversity in Mediterranean woodlands are yet unknown. To assess these effects on diurnal butterflies, we conducted daytime surveys in the Mt. Meron nature reserve (northern Israel) in two habitats over two different years. In each habitat we chose one site that was grazed by cattle and, as a control, a similar but ungrazed site. Belt transects (5m wide), divided for 100m replications, were surveyed five times on ridges in 2015 (11 replications, 538 butterflies, 25 species), and nine times in valleys in 2016 (12 replications, 3,944 butterflies, 38 species). In both habitats, species similarity index between sites was high. Richness was higher in the ridge control and evenness was higher in the valley grazed site. In both habitats total abundance was ca. twofold higher in the control, and the abundance of woody affiliated butterflies was threefold higher in the control, probably due to overgrazing, which affects butterflies’ breeding niches. For batha polyphagous and oligophagous butterfly species, abundance was similar between the sites, and for a few of those, associated with increaser plants, it was even higher in the grazed sites. However, the batha monophagous species were significantly more abundant in the control. Monophagous and endangered species were found to be more sensitive to cattle grazing. We conclude that the current cattle grazing management in Mt. Meron reserve affects butterfly populations negatively. Therefore, we recommend more regulated grazing and early-season deferment precautions, along with designation of no-grazing areas in reserves.

<p>This research aimed to figure out the santri’s preference toward studies and professions in which conduct study at pesantren. Common perceived and stated also at Government Ordinancenumber 55, 2007, that pesantren purposes was to reproduce Islamic scholar (ulama). However, through this study, it proved that not all santri wanted to be ulama, most of them wanted to be a scientist. This study was a case study, conducted in 2015 at Pesantren Alhikmah2 Brebes. Data collected using questionnaire, interview, and document. Those all derived from santris, Kyais, and teachers (asatidz). The research concluded as showed from questionnaire that santri’s  preferences toward study has gotten  changing to general subject matters instead of religious subject matters; and the santri’s professions and jobspreference has gotten changing to the jobs and professions that based on general subject matter, instead of choose to be ulama (Islamic scholar) most of santri wanted to be scientists, or researchers, or doctors as well as athlete.</p>

This article analyses the factors leading to the success of women candidates in the 2019 elections in Central Java. Recent scholarship on women’s representation in Indonesia has highlighted the role that dynastic ties and relationships with local political elites play in getting women elected in an environment increasingly dominated by money politics and clientelism. Our case study of women candidates in Central Java belonging to the elite of the Nahdlatul Ulama (NU)-affiliated women’s religious organisations Muslimat and Fatayat shows that strong women candidates with grassroots support can nonetheless win office. Using the concepts of social capital and gender issue ownership, and clientelism, we argue that women candidates can gain a strategic advantage when they “run as women.” By harnessing women’s networks and focusing on gender issues to target women voters, they are able to overcome cultural, institutional, and structural barriers to achieve electoral success even though they lack resources and political connections.

Coffee is among the most popular commodity crops around the globe and supports the livelihoods of millions of households along its value chain. Historically, the broader understanding of the roles of coffee has been limited to its commercial value, which largely is derived from coffee, the drink. This study, using in-depth interviews and focus group discussions, explores some of the unrevealed socio-cultural services of coffee of which many people are not aware. The study was conducted in Gomma district, Jimma Zone, Oromia National Regional state, Ethiopia, where arabica coffee was first discovered in its natural habitat. Relying on a case study approach, our study uses ethnographic study methods whereby results are presented from the communities’ perspectives and the subsequent discussions with the communities on how the community perspectives could help to better manage coffee ecosystems. Coffee’s utilities and symbolic functions are numerous—food and drink, commodity crop, religious object, communication medium, heritage and inheritance. Most of the socio-cultural services are not widely known, and hence are not part of the benefits accounting of coffee systems. Understanding and including such socio-cultural benefits into the wider benefits of coffee systems could help in promoting improved management of the Ethiopian coffee forests that are the natural gene pools of this highly valuable crop.
