Abstract

Lake of Open University (UT) is designed not only as a container, watershed, irrigation, sports, and recreation, but also as critical habitat for the survival of plants and aquatic animals ranging from algae groups to types of vertebrate. Information relating to the data microalgae and environmental conditions of lake UT physical and chemical have not been investigated. Research objectives were to measure the wealth of microalgae that live in Lake UT, the microalgae diversity, and the physical and chemical environment. The method used to identify each kind of microalgae, is by counting the number of individuals microalgae, and analyze the water quality. Measurement results showed that the brightness of the physical environment of the lake water had turbid category (52-60 cm). The temperature of the lake water showed 31 to 31.5 oC, this temperature range is good for the growth of microalgae. Value of the degree of acidity of water was 7.3 to 7.5. DO measurements generating valued from 0.5 to 0.57 mg/L. The wealth of microalgae that live in lake UT was identificated as many as 21 genera at four stations with a total population of 4.080 individual/mm3. The highest percentage individual was Scenedesmus sp. Species richness index was 3,33 (medium category). Highest individual density was found in th middle of the lake by 4.651 individualLitre, followed by a passage from edge of the lake to the edged of gazibu (2.318 individual/Litre), the edge of lake (2.025 individual/Litre), and the last outlet (1.193 individual/Litre) lake. Biodiversity index is quite low at 2.107. Desain pembuatan danau UT di samping sebagai tempat resapan air, wahana rekreasi, sarana olahraga, juga merupakan habitat penting bagi tumbuhan dan hewan air (golongan alga sampai jenis vertebrata). Informasi mengenai data mikroalga serta kondisi fisik dan kimiawi lingkungan danau UT belum diketahui sehingga perlu dilakukan penelitian. Tujuan penelitian untuk mengukur kekayaan mikroalga, keanekaragaman mikroalga, dan kondisi lingkungan fisik dan kimiawi. Metode yang digunakan adalah mengidentifikasi setiap jenis dan menghitung jumlah individu mikroalga, serta menganalisis kualitas air. Hasil pengukuran kecerahan air danau dikatakan relatif keruh (52-60 cm). Pengukuran suhu air menunjukkan besaran angka 31-31,5oC, kisaran suhu tersebut baik bagi pertumbuhan mikroalga. Nilai derajat keasaman air adalah 7,3-7,5, sedangkan hasil pengukuran DO sebesar 0,5-0,57 mg/L. Kekayaan mikroalga yang teridentifikasi di danau UT sebanyak 21 genus ditemukan di empat stasiun dengan total populasi 4.080 individu/mm3. Persentase jumlah individu terbanyak adalah Scenedesmus sp. Indeks kekayaan jenis termasuk kategori sedang (3,33). Kepadatan individu tertinggi ditemukan di stasiun-2 (bagian tengah) sebesar 4.651 individu/Liter, selanjutnya diikuti oleh stasiun-3 dari tepi danau sampai tepi gasebo (2. 318 individu/Liter), stasiun-1 di bagian tepi danau (2.025 individu/Liter), dan stasiun-4 di bagian keluaran air (1.193 individu/Liter).

Abstract

The different roles and responsibilities of male and female of the Osing tribe influence the knowledge of the use of plants. The aims of research is to analyze the values of the benefits of plants based on gender perception. The research used a qualitative and quantitative methods. Data collection for the value of plant species utilization were carried out  using Pebble Distribution Method (PDM) and analysis used Index of Cultural Significance (ICS). The Osing community recognised 86 plant species that were grouped in to eight beneficial groups. The male in three villages have a better understanding of ethnobotanical knowledge and practice than female on crops as staple foods, medicines, fruits, and firewood, while understanding of ornamental plants are relatively the same for both male and female. Female have a broader and more detailed understanding on vegetables, plant species used as building construction, and traditional rituals. The high PDM value in eight beneficial groups was supported by the high value of each ICS.

Abstract

In daily life, the interaction of the Osing people with their agricultural environment has resulted in various activities that have local wisdom values. All of these activities are still carried out in the midst of the rapid advancement of digital and online technology-based civilization. In addition, in their social life, the community is consistent in carrying out and preserving various traditional ritual traditions from their ancestral heritage. The research aims to make an inventory of various activities that have local wisdom values and record they carry out traditional conservation of the biological resources in their environment. The research used a qualitative descriptive method, while data collection was carried out through observation and interviews in Focus Group Discussions (FGD). The data analysis process uses cross-checking, summarizing, and synthesizing. The results showed that there were various activities of the Osing community that contained local wisdom values, including farming practices using the Javanese calendar (pranotomongso) and the history of making and placing garden lands that function as buffer areas for paddy fields to prevent landslides. ancestors of the Osing tribe. The division of tasks in farming activities in the rice fields carried out by men and women of the Osing tribe reflects a combination of activities that have aspects of local wisdom. Likewise, the use of straw as animal feed and natural organic fertilizers, as well as the use of a kettle, fishing tools, the use of hunting dogs to get wild animals, and skills in the process of making traditional tools. The Osing community carries out traditional ecosystem-based conservation to protect all plants that grow on their agricultural lands. In addition, in maintaining the sustainability of clean water springs (belik) along the banks of the Sobo and Gulung rivers, they do this by making a ban on cutting down trees that grow around the riverbanks and performing the rebo wekasan salvation ritual.

Abstract

Keberadaan Hylobates moloch (Owa Jawa) endemik di hutan-hutan konservasi seperti Taman Nasional Ujung Kulon, Gunung Halimun, Gunung Gede Pangrango, Cagar Alam Gunung Simpang, dan Leuweung Sancang, dan menurut IUCN Redlist status konservasi Owa tersebut termasuk dalam kategori endangered (genting). Penelitian bertujuan untuk mempelajari tingkah laku dan karakteristik Owa Jawa di Karantina Taman Margasatwa Ragunan (TMR). Metode kualitatif yang digunakan dalam penelitian adalah melakukan pengamatan langsung terhadap tingkah laku Owa Jawa dengan cara: a) deskripsi, b) ad libitum, c) focal sampling, dan d) scan sampling. Aktivitas harian hidup Owa Jawa yang mencakup makan dan minum, bergerak, beristirahat, serta bersosialisasi di Karantina TMR pada dasarnya mirip dengan perilaku Owa di habitat alamiahnya serta di Pusat Penyelamatan dan Rehabilitasi Owa Jawa (Javan Gibbon Center), Taman Nasional Gunung Gede Pangrango. Adanya kemiripan aktivitas harian hidup Owa Jawa mengindikasikan bahwa sudah selayaknya tidak ada alasan yang sangat mendasar dalam tata cara pemeliharaan maupun perawatan Owa Jawa di karantina TMR untuk tidak berhasil, sebaliknya harus berhasil dan berkembang menjadi lebih banyak.Kata kunci: Owa Jawa, tingkah laku, Taman Margasatwa Ragunan

Abstract

Coral reefs are one of the ecosystems that play an important role in coastal areas but are vulnerable to change. Ecologically, coral reefs act as habitats for various kinds of reef fish, in addition to functioning as beach protectors from the crashing waves of currents as well as a source of germplasm. The diversity of coral genera and other biota is one of the important indicators in supporting the sustainability of water tourism activities, especially snorkeling and diving. Areas that have relatively high diversity of coral reefs have more resilience in their role in protecting coastal areas so that their existence needs to be maintained in order to avoid extinction. This study aims to identify the names of coral genera and measure the percentage of coral cover in the Gili Sulat and Gili Lawang Water Tourism Parks (WTP). The method used in this research is the Point Intercept Transect (PIT) method and the Time Swim method. The results showed that 10 genera had been identified, namely the genus Acropora, Euphyllia, Fungia, Galaxea, Lobophyllia, Montastrea, Montipora, Pachyseris, Plerogyra, and Porites. The largest coral genera were Porites and Acropora which were spread on transects 1 and 7. The average coverage of the two corals was 32.34% in Gili Sulat and 39.64% in Gili Lawang.
