Digital Trust Dan Regulasi Marketplace: Studi Kasus Fenomena Penipuan Di Facebook
Get PDFDigital trust in online transactions, especially on the Facebook marketplace, has great potential in Indonesia. Despite regulations to protect consumers, fraud cases on this platform continue to rise, resulting in financial losses for users. There are criminals ostensibly selling on Facebook, who take advantage of system weaknesses to commit fraud. This phenomenon not only harms consumers, but can also damage the platform's reputation and hinder the growth of the digital economy in Indonesia. This research aims to analyze the legal protection for consumers in transactions on the Facebook marketplace and identify the responsibilities of criminals who are motivated to sell on the Facebook marketplace. The research method used is juridical-normative with a statutory approach (The Statue Approach) as well as secondary data from literature reviews, including laws and other legal sources. This research analyzes three cases of fraud that occurred in the Facebook marketplace, involving perpetrators with different modus operandi, ranging from the sale of counterfeit goods to organized fraud syndicates. The results show that legal protection for consumers in the Facebook marketplace is still not optimal, with several violations of consumer rights. An inefficient complaint system and lack of account mechanisms exacerbate this situation. The liability of criminal offenders is regulated under the ITE Law, and the Criminal Code, where they can be subject to severe criminal sanctions, including imprisonment and significant fines. In addition, the perpetrator also has the responsibility to compensate the victim for the loss caused. This study concludes that to create a safer online transaction environment, Facebook needs to make improvements in its security and consumer protection systems, as well as stricter law enforcement against fraudsters. In addition, educating users about the risks and how to protect themselves when transacting is also very important to reduce the number of frauds on this platform

Kaji Eksperimental Material HDPE Terhadap Kualitas Produksi Blowing dengan Pendekatan Ekonomis Melalui Komposisi Material
Get PDFIndonesia is the second largest contributor of plastic waste after China, with a volume of plastic waste produced of around 187.2 million tons. This large amount of plastic waste is very dangerous for the environment because plastic is nonbiodegradable, which takes around 20-100 years to decompose in the soil. This research aims to find the composition of the material mixture in the plastic production process. One method to reduce the accumulation of plastic waste is to recycle the plastic into products that can be reused. After going through several
stages, the results obtained from recycling plastic products are possible as ingredients for the
composition of mixed materials in the plastic production process. Then data was obtained from
the tensile test results of the original material + reheating with a maximum peak value reaching
3.716104 Mpa and the strain value increasing by 0.897150%. These results are close to the
original material obtained by tensile test data, the maximum peak value reached 6.175963 Mpa
and the strain value increased by 1.765665%. The composition of original material mixed with
reheating waste can be an alternative to original material as a material for the plastic production
process to make it more efficient and economical, but with the provisions of 70% original
material and 30% reheating waste

Regulasi Emosi Nabi Yusuf dalam Surat Yusuf (Studi Tafsir Fi Zilal Al-Qur'an)
Get PDFEmotions are something that can influence human actions. Allah Ta'ala has given every human
being an emotion to maintain stability in living life. Therefore, every human being has the right
to determine how and when emotions are expressed. However, recently, many events related
to emotional management have been in the spotlight. Cases such as excessive emotional
displays are no longer uncommon in various news stories published by well-known media. So
in this research we want to discuss how emotional regulation was taught by the Prophet Yusuf
in the Al-Qur'an, more precisely in Yusuf's letter according to the interpretation of Sayyid Qutb
in the Tafsir Fī Ẓilāl al-Qur'ān. With analysis of James Gross's theory of emotional regulation.
The research method that the author uses is a qualitative method with a type of library research
which is analyzed using a descriptive-interpretive approach. The results of this research are the
forms of emotional regulation carried out by the Prophet Yusuf, such as dhikr (remembering
Allah), patience (steadfastness in facing trials), prayer (expressing feelings and hopes to Allah),
and self-control in facing temptation, showing Prophet Yusuf's ability to manage emotions
constructively. In James Gross's theory of emotional regulation, the strategies used by the
Prophet Yusuf can be understood through the approach of situation selection, situation modification, attentional deployment, cognitive change and response change.
