Estimation of Carbon Dioxide Emission and Sequestration from the Cradle-to-Grave Life Cycle of Bioethanol from Nipa Palm (Nypa fruticans) Sap
No full textThe increasing demand for renewable energy has driven research into sustainable biofuel alternatives. This study evaluates the carbon balance of bioethanol produced from the sap of the Nipa palm (Nypa fruticans), a mangrove species with significant carbon sequestration potential. A cradle-to-grave life cycle assessment was conducted to estimate the total carbon dioxide (CO2) emissions from bioethanol production and compare it with the CO2 absorbed by the Nipa palm. The assessment covered emissions from transportation, fermentation, distillation, and distribution. The findings show that Nipa palms exhibit a substantial CO2 sequestration capacity, averaging 21,785 kg CO2/ha/year. The gate-to-gate emissions for producing 95% hydrous ethanol (H95F) and 99% hydrous ethanol (H99F) were calculated to be 1,075.91 kg CO2/ha and 11,552.94 kg CO2/ha, respectively. By comparing emissions against sequestration, the study reveals a significant positive carbon balance. The net balance for H95F production was -20,709.09 kg CO2/ha/year, and for H99F, it was -10,232.06 kg CO2/ha/year. This indicates that the bioethanol production system from Nipa sap is not only carbon neutral but carbon negative, as the Nipa palm cultivation absorbs more CO2 than the entire production process emits. Furthermore, compared to gasoline, which emits approximately 2.91 kg CO2-eq per liter, Nipa bioethanol presents a much lower carbon footprint. These results underscore the potential of Nipa palm bioethanol as a sustainable and environmentally beneficial fuel source that contributes to mitigating climate change by reducing greenhouse gas concentrations
Estimated CO
No full textThe primary energy supply in Indonesia is still dominated by fossil fuels, leading to a significant increase in CO2-eq emissions, particularly from the transportation and industrial sectors. The Indonesian government has implemented the B40 program (a blend of 40% biodiesel and 60% petroleum diesel) to mitigate CO2-eq emissions. This research aims to calculate the total CO2-eq emissions throughout the entire life cycle of B100 production based on the principles of Life Cycle Assessment (LCA) as specified in SNI ISO 14040:2016 and SNI ISO 14044:2017. The analysis compares the CO2-eq emissions of conventional diesel (B0) and B100. The results indicate that B100 has the potential to reduce particulate emissions by 40-60%, carbon monoxide (CO) by 10-50%, and hydrocarbons (HC) by 10-50% compared to B0. The CO2-eq emission factor for B0 was found to be 4,354.81 kg CO2-eq/kL, and for B100 it was 2,155.64 kg CO2-eq/kL. This demonstrates a significant reduction in emissions with the use of B100, resulting in a decrease of 2,199.17 kg CO2-eq/kL or 50.50% from B0. However, the study also highlights the environmental challenges associated with the expansion of oil palm plantations, including deforestation and land degradation, which contribute to CO2 emissions
DINAMIKA KONFLIK SURIAH PADA MASA PEMERINTAHAN BASHAR AL-ASSAD
Get PDFThis paper departs from the conflict that occurred in Syrian City, so it makes the author interested in trying to understand the basic problems that are the cause of the conflict. In addition, the author also tries to see who the actors who played a role in the conflict are, as well as the impact that the Syrian conflict has on the international world. The Syrian conflict has been going on for forty years to date, and the conflict has not yet seen its end. Since March 2011 the conflict in Syria has claimed so many lives, thousands of people have been displaced, and thousands of children orphaned. Many houses collapsed, infrastructure and public facilities were destroyed due to the conflict. Data on the Syrian conflict is collected from books, journals, and the web. These data are then categorized, systematized, and analyzed according to the purpose of writing. This paper concludes that the cause of the conflict in Syria is not due to differences in religious sects but rather the political and economic interests of the opposition opponents of Assad and opposition-supporting countries. There are three actors who play a role in the Syrian conflict: President Bashar al-Assad and his supporters, the Syrian opposition, and the Jihadist group. The resulting impact of the Syrian conflict is the large number of casualties that have fallen and the problem of refugees. From the time of the conflict in March 2011 to April 2013, The death toll was 150,000. Meanwhile, the displaced population is 2.4 million people, which is dominated by women and children. Meanwhile, 4 million Syrians are homeless. For the international community, the Syrian conflict has an impact on the handling of refugees
Exploring the Medieval Relationship between Islam and Christianity: Historical Context, Cultural Exchange, Religious Conflicts, and Significance
Get PDFThis research delves into the historical context, cultural exchange, religious conflicts, and significance of the relationship between Islam and Christianity during the Medieval. The study aims to gain an understanding of the complex dynamics, alliances, misunderstandings, and transformations that characterized this important era. By exploring primary sources, scholarly analysis, and historical records, this research uncovers the mutual influences, cultural exchanges, intellectual dialogues, and tensions arising from the coexistence and interaction of Islam and Christianity during the medieval period. The research contributes to a broader understanding of the historical legacies of Islam and Christianity, both separately and in relation to each other, highlighting the enduring consequences of their interaction on the development of religious traditions, intellectual thought, and cultural practices that continue to shape our world today. The author uses qualitative methods with literature study and documentation to collect historical information using historiography techniques. The results of the research show that this fluctuative relationship means that the relationship between the two religions cannot be fully generalized. There have been periods of cooperation and peace, but there have also been periods of tension and conflict between these two religions

Perancangan Sistem Komunikasi Menggunakan User Datagram Protocol Metode Unicast pada Robot R2C-Warrior
Get PDFRobotic Research Center (R2C) is a robotic team from Universitas Kristen Satya Wacana (UKSW). R2C has two divisions, one of them is R2C-Warrior team that took a part in wheeled soccer competition (KRSBI Beroda). When designing the robot, R2C-Warrior uses a laptop to process the algorithm and three Arduino microcontrollers to read sensors and drive an actuators. Uses Serial for communication between laptop and Arduino which is connected via the Universal Serial Bus (USB) port. Using Serial in this design has disadvantages, that are only one Arduino can connected to the laptop and the received data sometimes is lost or wrong with a data loss rate is 28% and data error rate is 4% in 1000 times data transmissions. To solve this problems, the author made a system using Ethernet instead USB with advantages can connect a laptop with three Arduino microcontrollers at once, and use User Datagram Protocol (UDP) with Unicast method instead Serial, because UDP has a checksum to ensure that sent or received data has no errors. Based on testing that has been done, this system has no data errors in testing data transmissions, both from laptop to Arduino, Arduino to laptop, and Arduino to Arduino. Other than that, this system doesn’t have a problems when there is no communication or when receiving data from unknown device(s), and also can filtered data when there is available data from unknown device(s)
Syukur Sebagai Fondasi Nilai-Nilai Pendidikan Islam: Studi Al-Qur'an Surat Al-Fatihah, Surat Luqman Ayat 12, dan Surat Ibrahim Ayat 7
Get PDFThe teachings and instructions of the Qur'an relate to various concepts that are really needed by humans in navigating their lives in this world and in the hereafter. Gratitude is considered one of the foundations of Islamic education. Islamic education aims to instill values such as faith, worship and morals in individuals to become better humans. The type of research that the author uses in this research is literature study. In life, no matter how small something we receive we should be grateful. Unfortunately, not everyone is able to direct the thoughts in their minds to always be grateful for what we get every day. Al-Qur'an There are many benefits from being grateful and there are also many bad things if we are not grateful. The Qur'an also explains that gratitude is a result and goal of the creation of the universe and also the most important result of the creation of living creatures is gratitude to Allah SWT.Ajaran dan petunjuk Al-Qur’an tersebut berkaitan dengan berbagai konsep yang amat dibutuhkan oleh manusia dalam mengarungi kehidupannya didunia ini dan diakhirat kelak. Syukur dianggap sebagai salah satu landasan pendidikan Islam. Pendidikan Islam bertujuan untuk menanamkan nilai-nilai seperti keimanan, ibadah, dan akhlak pada diri individu agar menjadi manusia yang lebih baik. Jenis penelitian yang penulis gunakan dalam penelitian ini adalah studi pustaka. Dalam hidup, sekecil apa pun sesuatu yang kita terima seharusnya disyukuri. Sayangnya tidak semua orang mampu mengarahkan pikiran yang ada di benaknya untuk selalu mensyukuri apa yang kita dapatkan setiap hari. Al-Qur’an Banyak sekali manfaat dari bersyukur dan banyak sekali juga keburukan apabila kita tidak bersyukur. Al-Qur’an juga menjelaskan bahwa bersyukur adalah sebuah hasil dan tujuan dari penciptaan alam semesta dan juga hasil paling penting dari penciptaan makhluk hidup adalah bersyukur kepada Allah Sw
