The results showed that addition of 60 mg/kg body weight (T4) of piperine significantly (P<0.05) reduced feed consumption, egg production, egg mass, income over feed cost (IOFC), and increased water consumption as compared to the other treatments. The addition of 15-60 mg piperine/kg body weight significantly (P<0.05) reduced eggshell weight and increased egg yolk color score. The conclusion of this experiment was that the addition of piperine at 15-45 mg/kg body weight could be used as phytogenic feed additive to improve performance, IOFC, haugh unit, and yolk color

Potret Nilai Kesufian dalam Kehidupan Bermasyarakat

The value of Sufism has appeared since the time of Prophet Muhammad SAW, so it is not difficult to trace when the seeds of Sufism began to emerge. In fact, the adherents of Sufism are regarded as the ancient society that is antipathy to the modernization and staying away from the life of the world. In fact, this assumption is wrong and far from the values of the truth of Sufism, because the actual teachings of Sufism in the community is to contribute the development of the society into a better society

Teachers’ Perception on Classroom Action Research

This research explores teachers’ understanding toward classroom action research. The study applied descriptive research method employing information from primary data related to teachers’ knowledge and perception on classroom action research in East Java Indonesia. The findings showed that about 84% teachers have tried to conduct classroom action research in their classroom, mainly because it is mandatory for them in order to improve their careers. Other than that, the curriculum changes in Indonesia forced them to conduct this kind of research to adjust to those changes. At a glance, they did not do this type of research voluntarily, but it turned out to be beneficial for their classes. The benefits are to solve classroom problems such as lack of critical thinking skill, low motivation, and lack of activities. It also improves students’ achievements in learning economics. Moreover, teachers feel more confident because they know how to use classroom action research to find out if students are learning from their lessons. However, the problems occurred in implementing classroom action research such as identifying the problem, proposing literature review and analyzing the data. &nbsp; &nbsp; Keywords: classroom action research, teachers’ perception, teaching and learnin

Towards improved socio-economic assessments of ocean acidification’s impacts

Ocean acidification is increasingly recognized as a component of global change that could have a wide range of impacts on marine organisms, the ecosystems they live in, and the goods and services they provide humankind. Assessment of these potential socio-economic impacts requires integrated efforts between biologists, chemists, oceanographers, economists and social scientists. But because ocean acidification is a new research area, significant knowledge gaps are preventing economists from estimating its welfare impacts. For instance, economic data on the impact of ocean acidification on significant markets such as fisheries, aquaculture and tourism are very limited (if not non-existent), and non-market valuation studies on this topic are not yet available. Our paper summarizes the current understanding of future OA impacts and sets out what further information is required for economists to assess socio-economic impacts of ocean acidification. Our aim is to provide clear directions for multidisciplinary collaborative research

Potential Analysis of Hydro Power Plants in Pesisir Barat District, Lampung Province

Hydropower plants are increasingly being heard nowadays, but the growth is still very lacking, especially for residents living in rural and coastal areas. At present several efforts have been made by the government, including the existence of a system of purchasing electricity from small-scale renewable energy generation and the construction of new transmission networks. Pesisir Barat Regency is part of the South Lampung region, Sumatra. This region has a population distribution in the coastal area and is surrounded by Bukit Barisan National Park. So that there are many large river streams that can be utilized by the local community. Large rivers have the potential to be utilized further as hydropower renewable energy sources. River potential is seen by conducting river location surveys, flow measurements and river heads and power calculations. Based on the analysis of measurement results there are two rivers that have the potential to be a micro or mini hydro generator; Way Laai and Way Lami. The maximum design discharge of Way Laai of 4.52 m3/s can produce a mechanical output power of 1223.82 kW with an effective head of 44.16 m. Way Lami with a design discharge of 5,336 m3/s, an effective head of 28.8 m has the potential to provide a mechanical power output of 942.23 kW. Sequentially, with this mechanical output power, the Way Laai and Way Lami rivers, can meet the electricity needs of the community with an installed power of 900VA as much as ± 1350, ± 25100 Houses
