    Lichen of the genus Usnea is quite common being used as a traditional herbal remedy. This genus is characterized by thallus, which is very similar among the species, leads to some difficulties in distinguishing them. In Indonesia, such research report on the availability of this genus based on their morphological characteristic is minimal. This might be due to too high morphological similarities among them. The molecular character, which is based on the DNA Barcode of Internal Transcribed Spacer (ITS) rDNA sequences, with its conserved region (5.8S) and varied region (ITS1 and ITS2), are becoming essential characters on identifying as well as analyzing the phylogenetic. The current study then proposed to identify and draw the species dendrogram of species within the Usnea genus obtained from Mount Lawu Forest of Central Java and Turgo Forest of Yogyakarta based on their phylogenetic and phenetic analysis. The dendrogram was constructed with UPGMA using the simple matching coefficient, whereas the phylogenetic tree was constructed with Maximum Likelihood (ML) using Kimura-2 parameter with 1000 bootstrap. The data were unable to draw phenetic relationships among the subgenus Usnea and Eumitria members. The phylogenetic tree shows the primary two clades, distinguishing the subgenus Usnea and Eumitria. The ITS rDNA sequence was able to identify most of the Usnea species

    Effect of food waste on the growth performance, waste reduction efficiency and nutritional composition of black soldier fly (Hermetia illucens (L.), Diptera: Stratiomyidae) larvae

    The rate of solid waste generation, especially in Malaysia, has become one of the major concerns for environmental and public health issues. Food waste accounts for the highest percentage of solid waste that ends up in landfills. Due to the living nature of humans and their involvement in agricultural, industrial, and municipal activities, the disposal of food waste happens on a regular basis. Due to the absence of an incineration plant, these wastes are commonly sent into landfills which are considered to be the most cost-effective method for disposal. Nevertheless, consideration for an alternative disposal method such as composting shall not be ruled out entirely. One of the established methods for composting food waste is the utilization of the larvae of the Black Soldier Fly. A study was conducted to assess the growth and nutritional composition, waste reduction capacity and nutritional composition of Black Soldier Fly Larvae (BSFL) reared on food waste. We found that the larvae reared with the food waste and effective microorganism (EM), LFWEM (BSFL reared with a mixture of food waste and effective microorganisms), have a slightly better relative growth rate (2.66 ± 0.35 day-1) compared to larvae reared with only food waste (2.44 ± 0.17 day-1). The waste reduction index was higher in the LFWEM group (5.36 ± 0.18 g/day) compared to the control group, LFC (BSFL reared with chicken feed) (4.85 ± 0.03 g/day) and the LFW (BSFL reared with food waste) group (5.13 ± 0.17 g/day). The nutritional composition of the BSFL reared using food waste shows some potential as it surpasses some of the amount of essential amino acids including Arginine, Histidine, Threonine and Valine, found in the commercially available animal feeds. This finding serves as a baseline to propose potential replacements for animal protein by using BSFL reared with food waste

    Quality of school facilities and instructional tools are essential to the academic success of both students and teachers while low-standard facilities have an adverse influence on performance in terms of education as well. Malaysian government through the Ministry of Education (MOE) are spending millions to ensure enhancement of quality education in Malaysia especially for the restoration, refurbishment, and formation of new and outdated schools. Lack of maintenance can result in unsafe, unhealthy, and hazardous environment towards students, teachers and supporting staffs that served the public schools. To reduce the economic burden, MOE has launched Maintenance Fund for Government Schools and Public Institutes of Higher Learning which is fully administered by themselves through the crowd-funding concept. Since the concept is still new especially in the context of public education in Malaysia, the attention of this research is to investigate and understanding the factors that might affect potential investors' willingness to contribute to the initiative of crowd-funding. This paper has explained and further justified the extension of UTAUT model which originally used in most of the technology acceptance. The UTAUT has been expanded to also include trustworthiness as new additional variable to complement the original UTAUT. The framework of this study has been developed to improve the understanding of crowdfunding acceptance among the potential investors. To test the framework, data has been collected by using 23 items of structured questionnaire of 5-point Likert scale from 384 potential investors in Melaka. Multiple linear regressions were employed to support the data analysis. The research result indicates that all the independent variables were statistically significant and positive relationships were established. These outcomes suggest that the inclusion of trustworthiness in UTAUT model has increase the prediction level toward potential investors of crowdfunding. Furthermore, it is worth noting that trustworthiness also recorded the highest impact toward the intention to invest among the potential investors. Since the maintenance expenses in government school through crowdfunding is rather new in Malaysia, the findings from this study could assist the government to legalise the crowdfunding which could also be extended to other government services and facilities such as colleges, universities, and the likes. Furthermore, this research can be used as a guide or a reference by industry professionals trying to increase public interest in contributing to a crowd-funding effort. Finally, this study is planned to serve as guideline and policy implication for future government crowd-funding efforts

    Thermal comfort is vital in office building for work performance improvement. This paper compares the thermal comfort in the naturally ventilated and mechanically ventilated office building in tropical wet Savanna (India) and winter Mediterranean climates (United Kingdom). The data was retrieved from the ASHRAE Global Thermal Comfort Database II and statistically analyzed by SPSS. Total of 160 samples were retrieved from the database and the correlation between thermal comfort parameters with PMV index value and linear regression analysis was conducted. Results of the study shows that for the naturally ventilated office, the thermal comfort temperature range was between 22.60℃ to 25.47℃ for India and wider range of 17.47℃ to 24.38℃ for the United Kingdom. On the other hand, the thermal comfort temperature range for a mechanically ventilated office in India was between 26.16℃ to 27.06℃ while for the United Kingdom, was between 20.63℃ to 24.94℃. In conclusion, wider thermal comfort range was found in the United Kingdom for both type of office ventilation especially for the naturally ventilated office. This was in the same agreement with the lower level or relative humidity, air velocity and higher clothing insulation value among the United Kingdom respondent

    Perkembangan teknologi yang semakin cepat dan selalu menjadi tren terhadap gaya hidup masyarakat telah merubah cara berfikir dan memilih dalam melanjutkan pendidikan tinggi. Hal ini juga menjadi inspirasi bagi perguruan tinggi yang telah berdiri untuk menerapkan pengembangan berbasis teknologi. Penggunaan teknologi akan mempercepat sebuah universitas masuk dalam daftar perguruan tinggi yang menjadi pilihan masyarakat domestic ataupun internasional. Inovasi berbasis teknologi dalam pengelolaan perguruan tinggi telah melahirkan banyak terobosan untuk menyelesaikan isu permasalahan yang selama ini akut terjadi pada universitas. Salah satu konsep pengembangan perguruan tinggi yang saat ini sedang tren adalah berbasis smart campus. Dalam rangka menyikapi pertumbuhan perguruan tinggi di Indonesia dan dunia yang semakin kompetitif, diperlukan pengelolaan yang selalu inovatif sehingga bisa bertahan dan berkembang. Persaingan tersebut juga memerlukan pengelolaan yang tidak saja hanya berbasis manajemen konvensional kekuasaan tetapi diperlukan revolusi dan terobosan-terobosan di luar kebiasaan. Di usianya yang ke-59, UIN Maulana Malik Ibrahim Malang harus lebih melejit lagi dalam memberikan kebermanfaatan terhadao umat manusia. Buku ini merupakan konsep awal smart campus yang diterapkan di UIN Maulana Malik Ibrahim Malang
