Preparation of proton exchange membrane by radiation-induced grafting method : Grafting of styrene onto poly(ethylene tetrafluoroethylene) copolymer films

Radiation induced grafting of styrene onto poly(ethylene-tetrafluoroethylene) (ETFE) copolymer film was carried out to prepare graft copolymer (ETFE-g-polystyrene) that can host sulfonic acid groups and form proton exchange membrane for polymer electrolyte fuel cell (PEFC). The effect of monomer concentration and type of solvent on the degree of grafting was investigated. The formation of graft copolymer film was confirmed by FTIR spectrum analysis

The Sociology of Law Study on the Impact of LGBT People in Social Life

The current research was carried out to determine the impact of Lesbian, Gay, Bisexual and Transgender (LGBT) phenomena in social life on the consequences. Conducted through qualitative method, such systematic approach was chosen because it was in line with the concept and scope of the problems related to issues, data or information on particular facts and events. The results of this study demonstrated that any behavior that was contrary with the expectations of society or did not conform to social norms and values were called as deviant behaviors. Currently, LGBT phenomena in Indonesia are still considered deviant and do not follow dominant norms in society. Phenomenon focuses its intervention on the process of interaction among well-beings and their environment, using theories of behavioral deviance in use, as tools or ways to govern the behaviors of community members to meet the norms and values in society. The findings of the present study revealed that LGBT has impacts on health, social, education, and also the security in society. Moreover, LGBT seen from the sociology of structural functionalism is kind of deviation because it is contrary to socially human nature and also contrary to the dominant values and norms in society

The potential of kabuyutan sacred natural site towards a sustainable landscape management in Indonesia

4th International Conference of the Transdisciplinary Research on Environmental Problems in Southeast Asia 16/09/2021 - 18/09/2021 OnlineSacred natural sites have been recognized by International Union for Conservation of Nature (IUCN) as a landscape heritage that contains biological and cultural diversity due to conserved over generations and sacred by indigenous people. This study identified the characteristics and ecological significance of kabuyutan, a sacred natural site perceived by Sundanese people in West Java Province, Indonesia. The observation participant method was used to gain a close and intimate relationship between Sundanese people and their natural and cultural environment, particularly kabuyutan. We identified 33 kabuyutan and found a typical structure compared to the surrounding landscape which is dominantly covered by dense vegetation and marked by sacred trees, springs, ancestor's graves, or stones. Kabuyutan were perceived to have a vital role in conserving land and water, which is proven by their specific land variables, and proposed a watershed-based management concept. However, we found that changes in the buffer zone of kabuyutan into the agricultural or residential area have potentially affected their existence due to the land ownership status. We suggested that empowering custodians and transferring information about the critical role of sacred natural sites are necessary for landscape management to prevent the negative impact of landscape dynamic

Tingkat Keberhasilan Hidup Bibit Mangrove Rhizophora Mucronata, R. Apiculata Dan Bruguiera Gymnorrhiza Di Delta Upang Banyuasin Sumatera Selatan

The research of the survival level of mangrove seed Rhizophora mucronata, R. apiculata and Bruguiera gymnorrhiza had been conducted during August to December 2009 in Upang Delta, Banyuasin. The objective of conducting this research was to find out the percentage of survival level of mangrove seed Rhizophora mucronata, R. apiculata, and Bruguiera gymorrhiza and to obtain some information to analyzed the level of adaptation among those three species of mangrove seed. The decision of survival level was observed based on the ability to live (%), the height of bud (cm), the number of leaf it has (sheet), and the stem illustration of observed object through sample data under such circumstances. The rate's of presentation lives mangrove seed from threes station. First station Rhizophora mucronata 100-73,3 %, R. apiculata 100-60 % and Bruguiera gymnorrhiza 100-66,6 %. Second station, Rhizophora mucronata 100-66,6 %, R. apiculata 100-86,6 % and Bruguiera gymnorrhiza 100-73,3 %, on third station, Rhizophora mucronata 100-66,6 %, R. apiculata 100-80 % and Bruguiera gymnorrhiza 100-66,6 %. The level adaptation of but has changed comparisons of stem diameters and quantity of leaf.

Operative temperature and thermal sensation assessments in non-air-conditioned multi-storey hostels in Malaysia

This study assessed the influences of operative temperature on occupants’ perceptions of indoor thermal condition in three non-air-conditioned multi-storey hostels in Klang Valley, Malaysia. The thermal conditions of 24 measured rooms were recorded with and without an operating ceiling fan from May until July 2007. Measurements were made simultaneously at three different floor levels, namely, at the first, fifth and top floor of each of the case study hostels. A questionnaire survey was completed by 298 female student occupants of the same case study hostels. The results suggested that even though a significance above p < 0.01 was recorded between the operative temperatures with and without fan operation, the temperature difference remained small, i.e., from 0.5 K to 1 K. The findings of the questionnaire survey showed that the occupants perceived the thermal conditions in rooms that were shaded with a projected balcony (shading ratio of 0.9), a long roof overhang (shading ratio of 1.6) and an operable window-to-wall ratio of 0.3 to be thermally comfortable

Kesesuaian Rumus Schrool dan Pita Ukur terhadap Bobot Badan Sapi Brahman Cross di Kelompok Ternak Sumber Jaya Dusun Pilanggot Desa Wonokromo Kecamatan Tikung Kabupaten Lamongan

Usaha peternakan Sapi Brahman Cross (BX) hingga saat ini masih didominasi oleh peternakan rakyat dengan skala USAha kecil dan sistem pemeliharaannya bersifat tradisional. Sistem pemasaran Sapi di wilayah Kabupaten Lamongan masih menggunakan metode taksiran. Salah satu cara untuk memperkirakan bobot badan adalah dengan mengukur lingkar dada ternak karena lingkar dada seekor ternak memiliki korelasi yang sangat kuat untuk menduga bobot hidup ternak. Beberapa cara yang dapat digunakan untuk menentukan bobot hidup ternak adalah menggunakan rumus Schoorl dan pita ukur. Penelitian ini dilaksanakan di Kelompok Ternak Sumber Jaya Kecamatan Tikung Kabupaten Lamongan. Materi yang digunakan dalam penelitian ini adalah Sapi Brahman Cross (BX) sebanyak 30 ekor. Data hasil penelitian dianalisis menggunakan Uji-T. Hasil penelitian menunjukan bahwa nilai T hitung (t) antara rumus Schoorl dengan timbangan Digital lebih besar dari T tabel (t0,05) yaitu (t = 76,26 ≥ t0,05 = 2,056), nilai T hitung (t) antara pita ukur dengan timbangan Digital lebih besar dari T tabel (t0,05) yaitu (t=52,5 ≥ t0,05 = 2,056 ). Hasil tersebut menandakan bahwa terdapat penyimpangan yang signifikankan dalam pendugaan bobot badan Sapi Brahman Cross di Kelompok Ternak Sumber Jaya Kecamatan Tikung Kabupaten Lamongan
