Uji Potensi Anti Kanker Ekstrak Biji Pinang Merah dan Implementasinya dalam Pembelajaran Mitosis

This research aims to determine the anticancer potential of Areca vestiaria Giseke extract and it\u27s effective concentration as anti-cancer, as well as determine the feasibility of mitosis worksheets for third grade of senior high school based on research result. Therefore research consisted of two phases. First phase is anti-cancer potential of Areca vestiaria Giseke using the experimental method with 3 treatments, 2 replications and 1 control (0 ppm). Data were analyzed by regression test. Second phase, the feasibility of the development of research results in the form of worksheets investigated by descriptive methods. Worksheets was validated by five validators, i.e. two lecturers and three senior high school teachers who teach Biology in Pontianak City. Based on the calculation of linear regression, y = -1,005+0,026 x. The results showed that Areca vestiaria Giseke extracts have a potency for as anti-cancer with 1.972 ppm. The validity score mitosis worksheets was 3,51 which categorized as valid, the worksheet are suitable to be used in the learning process, especially for sub material mitosis

Housing Morphology and Connectivity Quality in Periphery of Bandung City: Space Syntax Analysis

The complexity that occurs in the city is determined by its diversity and intensity of inhabitant activity. The connectivity system becomes an essential factor to accommodate these lively activities, especially connectivity of the housing area to the working area and public facilities. Periphery area of some metropolitan city including Bandung City has been growing Fast, which is influenced by the intense need for housing accommodation, as well as accommodation of educational and industrial sectors. The East Peri-Urban of Bandung City in this decade became a more high density, especially along the primary arterial road that connects the Western and Eastern area of Bandung. This study aims to analyze the morphology of housing development and its connectivity including road networks that located in three area of the East Bandung from 2007 to 2017: Jatihandap, Pasir Impun, and Cijambe corridors. Space Syntax analysis is conducted to perform this morphology study. Data collected by direct observation and secondary sources review that related to the development of housing settlement in the area. It is concluded that the development of housing morphology in the peri-urban area of Bandung within ten years is growing intensively. There is some dis-integration pattern of road connectivity in the case study, which tends to be isolated or can be called as “big housing pocket”. The connectivity or permeability of the housing area in the peri-urban city is urgently needed to intervene, in order to reduce isolated settlement pattern and daily heavy traffic
