New Record Marsdenia tenacissima (Asclepiadoideae, Apocynaceae) In Gunung Ijo Baturagung Yogyakarta Widodo Widodo; Muhammad Ja'far Luthfi
Biology, Medicine, & Natural Product Chemistry Vol 5, No 1 (2016)
Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

Marsdenia tenacissima population were found among wild bushes at S 07 o 47’ 03.4”; E 110o 30’ 48.0” about 415 meter above sea level in Gunung Ijo Baturagung Yogyakarta. Identification was based on literature and herbarium specimen. The research was conduct using exploration methods, morphoanatomical observation, and specimen collection. Marsdenia tenacissima in Jawa was not reported in Flora of Java. Marsdenia tenacissima habitus was liana. The specific character for its identification was pollinia’s structure. This paper presented other important character namely leaf, stem, flower, pollinia, and fruit of Marsdenia tenacissima in Gunung Ijo Baturagung Yogyakarta. Accurate description and examination of any plant species were needed for its conservation and awareness of public to local biodiversity.

Local Stability Analysis of a Mathematical Model of the Interaction of Two Populations of Differential Equations (Host-Parasitoid) Anggreini, Dewi

Mathematical model has many benefits in life, especially the development of science and application to other fields. The mathematical model seeks to represent real-life problems formulated mathematically to get the right solution. This research is the application of mathematical models in the field of biology that examines the interaction of the two populations that host populations and parasitoid populations. This study differs from previous studies that examine the interaction of two more species that prey and predators where predators kill prey quickly. In this study the parasitoid population slowly killing the host population by living aboard and take food from the host population it occupies. In this study of differential equations are used to construct a mathematical model was particularly focused on the stability of the local mathematical model of interaction of two differential equations that host and parasitoid populations. Stability discussed in this study are stable equilibrium points are obtained from the characteristic equation systems of differential equations host and parasitoid interactions. Type the stability of the equilibrium point is determined on the eigenvalues of the Jacobian matrix. Analysis of stability is obtained by determining the eigenvalues of the Jacobian matrix around equilibrium points. Having obtained the stable equilibrium points are then given in the form of charts and portraits simulation phase to determine the behavior of the system in the future.

Determination of Leisure Levels of Village Patronage UIN Sunan Kalijaga Yogyakarta: Improving Governance Patronage towards Rural Green Village and Environmentally Friendly Supriatna Supriatna; Thaqibul Fikri Niyartama; Iwan Kuswidi

Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

This study took place in the village of Patronage UIN Sunan Kalidjaga Yogyakarta that consist of 13 hamlets (Klidon, Banjarsari, Wonosalam, Dongkelsari, Puntuk, Tanjung Sari, Karang Lo, Purworejo, Tanjung, Banturejo, Nglengkong and Surirejo), Sukoharjo Village, District Ngaglik, DIY Sleman regency. Data are collect and analysed in order to obtain results in a level of comfort. The analysis was performed by using a formula based on the comfort level Temperature Humidity Index (THI). The results showed that Hamlet Klidon, Banjarsari, Wonosalam, and Dongkelsari shows Not Comfortable, whereas Hamlet Puntuk, Tanjung Sari, Karang Lo, Purworejo, Tanjung, Banturejo, Nglengkong, Surirejo and Mujen show Strongly Comfortable mainly on the clock 10:00 to 15:00.

Modified Alizarin Red S-Alcian Blue Staining for Reptilian Skeleton Muhammad Ja’far Luthfi
Biology, Medicine, & Natural Product Chemistry Vol 5, No 1 (2016)
Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

Skeletal staining is an important method in anatomical study. The aim of the research was to develop staining and clearing method of Reptilian skeleton using Alizarin Red S-Alcian Blue. The specimen were eviscerated, fixed, stained, cleared, and keep in glycerine solution. This modified double-staining has successfully stain bone and cartilage of Reptilian.

Checklist of Macroalgae in Waisai Coast, Raja Ampat Retno Suryandari; Widodo Widodo
Biology, Medicine, & Natural Product Chemistry Vol 5, No 1 (2016)
Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

Macroalgae are very abundant organisms in Indonesian coastal zone. They comprise 8.6% of the total marine organisms.The aim of the research was to identify macroalgae in Waisai Coast Raja Ampat. The results showed that 38 macroalgae were found in Waisai Coast Raja Ampat but only 29 species of macroalgae can be identified. Macroalgae found in Waisai Coast Raja Ampat are green algae, red algae and brown algae. Green algae found and identified are Caulerpa macra (Weber-van Bosse) Draisma & Prud’homme, Caulerpa racemosa var. macrophysa (Sonder wx Kutzing) W.R.Taylor, Caulerpa sertularoides (S.
