Abstract

Distribution of spiders in all colonized environments is limited by biotic and abiotic factors requiring adaptations with respect to, for example microhabitat choice and hunting behavior. These two factors were frequently used to group spiders into functional groups. In this study our objectives were to (i) group of genera of spiders into functional group based on their microhabitat specificity, hunting behavior, and daily activity; and (ii) compare the number and composition of functional group of spider at each habitat type and period of paddy growth. The study was conducted at a landscape dominated by paddy fields in Cianjur Watershed for a period of 9 months. Four different habitat types (paddy, vegetable, non-crop, and mixed garden), were sampled using five trapping techniques (pitfall traps, farmcop suction, sweep netting, yellow-pan traps, and sticky traps). The Unweighted Pair-Group Average and the Euclidean Distances were used to generate dendrogram of functional group of spider. We found 14 functional groups of spider at genus level. The number of functional group of spider at four habitat types was differing, but the composition was similar, because all habitats were closed to each other. Habitat structure diversity and disturbance level influenced the number of functional group of spider. Different architecture of vegetation and availability of differ prey during paddy growth, causing the composition of functional group of spider in each period of paddy growth was changed, although its number was unchanged. Key words: spiders, functional group, agricultural landscape, Cianjur Watershed

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui determinan karakteristik perusahaan dan struktur kepemilikan sebagai pendorong, peningkatan struktur modal, kinerja keuangan, serta nilai perusahaan pada perusahaan konsumsi di BEI. Data populasi dalam penelitian ini adalah semua perusahaan Konsumsi yang pada periode tahun 2009 sampai dengan tahun 2016 telah go Publik Pemilihan dan penentuan sampel pada penelitian ini dilakukan berdasarkan tehnik purpusive sampling yaitu tehnik penarikan sampel yang dilakukan secara sengaja berdasarkan kriteria yang ditetapkan peneliti. Tepatnya Judgement Sampling, dimana sampel yang dipilih menggunakan kriteria tertentu yang harus sesuai dengan tujuan penelitian. Perusahaan Konsumsi merupakan perusahaan yang sangat penting. Perusahaan yang mampu membantu menggerakan ekonomi, membantu pemerintah, menciptakan banyak lapangan pekerjaan, namun bahan baku masih banyak tergantung bahan impor. Pemerintah diharapkan dapat membuat kebijakan yang dapat menjaga Makro ekonomi terutama stabilitas nilai rupiah. Melakukan perbaikan infrastruktur yang bisa berdampak efisien dalam distribusi barang dan membuka peluang konsumen baru. Kata kunci: karakteristik perusahaan, nilai perusahaan, investor

Abstract

Laba-laba merupakan salah satu agens pengendalian hayati yang sangat potensial pada ekosistem sawah. Keberadaan laba-laba pada ekosistem sawah diduga dipengaruhi oleh cara bercocok tanam. Penelitian ini bertujuan untuk mengetahui keanekaragaman laba-laba pada ekosistem sawah di Pulau Lombok, serta melihat pengaruh cara bercocok tanam (monokultur dan polikultur) terhadap keberadaan laba-laba pada ekosistem tersebut. Penelitian dilakukan pada ekosistem sawah di Desa Tanjung Karang dan Lingsar, Kabupaten Lombok Barat, pada bulan Mei sampai Agustus 2006. Pengamatan laba-laba dilakukan dengan perangkap jebak dan jaring ayun. Pada penelitian ini didapatkan 328 individu laba-laba dari 50 spesies, 30 genera, dan 11 familia. Pada ekosistem sawah polikultur, keanekaragaman dan kekayaan spesies laba-laba lebih tinggi dibandingkan dengan ekosistem sawah monokultur. Lahan pertanaman yang dikelola secara polikultur dapat menciptakan struktur habitat yang lebih kompleks sehingga lebih banyak spesies laba-laba yang dapat berkoeksistensi di dalamnya.

Abstract

Coral reefs, mangroves and birds are becoming the major attraction of tourism in three islands - Gili Meno, Gili Air and Gili Trawangan (Gili Matra) - Lombok, Indonesia. Since the launching as a conservation area in 1993, tourism in Gili Matra has grown rapidly. On the other hand, the ecosystem continues to be degraded. Sooner or later, the ecosystem degradation will affect tourism and economic sustainability of the community in Gili Matra. The purposes of this study were to identify the stakeholders, and to map the ecosystem management problems in Gili Matra, to provide the basis for policy making in the future. The research method was depth interviews and focus group discussion (FGD). Identification of stakeholders was conducted using stakeholder analysis, while mapping of ecosystem management problems was carried out by participatory mapping. The stakeholders, who manage the ecosystem as tourism assets in Gili Matra, are: government, community and businessmen. The fishermen, tourists and businessmen are the primary stakeholders, meaning they have a high interest and the greatest influence on ecosystem management. Destructive behavior of stakeholders, especially the main stakeholders has led to the degradation of the ecosystem in Gili Matra, so it is important to nurture these stakeholders, to sustain tourism and economic viability of the community in Gili Matra.

Abstract

Agricultural practice is suspected to influence the availability of spiders in cashew plantation. The aim of this research was to study the diversity of spider in two different agricultural practices: monoculture and polyculture. The research was conducted in cashew plantations in Desa Kayangan (monoculture) and Desa Salut (polyculture), Lombok Utara. Two trapping techniques were used to sample the spiders: sweep net and pitfall trap. In each study area, 10 sampling sites were selected along line transect that was 5000 meters long. The study found 36 species of spiders from 12 families. The diversity and richness of spiders were higher in the polyculture cashew plantation than that in monoculture. Habitat structure was more complex in the polyculture cashew plantation; hence many species of spiders were able to coexist there.
