The study proposed identifying the changes in bacterial community and diversity and exploring the potential correlations among sediments parameters and benthic bacterial communities under different mangrove ecosystems rehabilitation statuses. There were three sites: 1. Banyuurip Mangrove Center (BMC) as a restoration site; 2. Pulau Lusi (PL) as a degraded site; and 3. Kampung Blekok (KB) as natural site. The physicochemical parameters and benthic bacteria from the mangrove sediment of the three locations were observed. The data were analyzed statistically to determine the sites' variation and the correlation between parameters. The results found that the physicochemical parameters among restoration sites varied. Soil organic matter (SOM) in natural and restoration sites was significantly higher than in degraded sites. Cation exchange capacity (CEC), calcium and potassium ions, and soil conductivity of the restoration site were considerably higher than the other sites. According to diversity indices and taxa richness, benthic bacteria in the restoration were the most diverse. Proteobacteria dominated in natural and restoration sites; meanwhile, Firmicutes dominated in degraded site. Sulfurovum aggregans was found abundant in natural and restoration sites; meanwhile, Mesobacillus subterraneus was the dominant species in the degraded site. Furthermore, the bacterial taxa richness was positively correlated with SOM and the bacterial diversity was correlated with CEC and conductivity.

The purpose of this study was to determine the Handling of Social Conflict in the Community Through Restorative Justice (Restorative Justice) at the East Bintan Police. In this study, the sample consisted of 3 police officers from the East Bintan Police and 5 people from East Bintan who had undergone Restorative Justice. The sample in this study was 5 people. The data analysis technique used in this study was a qualitative descriptive data analysis technique. Based on the results of the study, it can be concluded that the Handling of Social Conflict in the Community Through Restorative Justice at the East Bintan Police has been running well, this can be seen from the police conducting investigations to collect evidence and information related to the reported cases, bringing in witnesses, listening to both parties. The police of course seek the best solution, especially in social cases that exist in the community. There are at least three focuses of restorative justice. First, repairing losses caused by crime by involving victims. Second, seeing the perpetrator's accountability. Finally, preventing similar losses in the future. Then there is a deliberation, Actually Restorative Justice is a method, not a form of decision on crimes as a resolution to solving problems by improving the situation or losses for victims. The principle of Restorative Justice is to restore good relations between the perpetrator and the victim, by paying attention to the victim's suffering.

A call option is a type of option that grants the option holder the right to buy an asset at a specified price within a specified period of time. Determining the option price period of time within a certain period of time is the most important part of determining an investment strategy. Various methods can be employed to determine the prices of options, such as Quasi-Monte Carlo and Monte Carlo simulations. The purpose of this research is to determine the price of European-type call options using the Quasi-Monte Carlo method. The data used is daily stock closing price data on the Apple Inc. for the period October 1, 2021, to September 30, 2022. Apple Inc. stock options in this study were chosen because it is the largest technology company in the world in 2022. The steps taken in this study are to determine the parameters obtained from historical data such as the initial risk-free interest rate (r), stock price (, volatility , maturity time (T), and strike price (K). Next is to generate Halton’s quasi-randomized sequence and simulate the stock price by substituting the parameters by substituting the parameters. Then proceed to calculate the call option payoff and estimate the call option price by averaging the call option payoff values. The results showed that the call option price of the company Apple Inc. using the Quasi-Monte Carlo with Halton’s quasi-randomized sequence on the 1000000th simulation with a standard error of 0,045 is $90,163. The call option price obtained can be used as a reference for investors in purchasing options to minimize losses from call option investments in that period.

This study aims to address two primary questions: Why does sexual violence occur in Islamic boarding schools (pondok pesantren)? How can sexual violence in these institutions be prevented? The methodology employed is a literature review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The data collection process involves four stages, starting with inclusion and exclusion criteria using Google Scholar with keywords such as Sexual Violence in Islamic Boarding Schools and Inclusive and Gender-Responsive Education in Islamic Boarding Schools. The findings reveal that the root causes of sexual violence in Islamic boarding schools are the hierarchical relationship between the kiai (religious leader) and the santri (students), the perpetuation of patriarchal culture, and the total obedience of the santri to the kiai. These factors also contribute to the underreporting of sexual violence cases, as victims and their families often feel intimidated. To address this issue, gender-inclusive education is necessary, manifested through a Gender Equality Curriculum (KKG). This curriculum ensures that all components involved in the educational system adopt gender-responsive thinking and behavior based on justice and gender equality. Gender-inclusive education will also create a non-segregated learning environment.AbstrakPenelitian ini bertujuan untuk menjawab dua pertanyaan utama: Mengapa kekerasan seksual di pondok pesantren bisa terjadi? Bagaimana upaya pencegahan kekerasan seksual di pondok pesantren? Metode yang digunakan adalah studi literatur berdasarkan Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Proses pengumpulan data melibatkan empat tahapan, mulai dari tahap inklusi dan eksklusi menggunakan mesin pencarian Google Scholar dengan kata kunci Kekerasan Seksual di pondok pesantren dan Pendidikan Inklusif dan Responsif Gender di pondok pesantren. Hasil penelitian menunjukkan bahwa akar masalah kekerasan seksual di pondok pesantren disebabkan oleh adanya hierarki antara kiai dan santri, pelanggengan budaya patriarki, dan kepatuhan total santri kepada kiai. Ketiga faktor ini juga menyebabkan kasus kekerasan seksual di pondok pesantren jarang dilaporkan karena korban dan keluarganya merasa takut. Untuk mengatasi hal tersebut, diperlukan pendidikan inklusif gender yang termanifestasi melalui kurikulum kesetaraan gender (KKG). Dengan adanya kurikulum ini, semua komponen dalam sistem pendidikan akan memiliki pola pikir dan perilaku yang responsif gender, berbasis keadilan dan kesetaraan gender. Pendidikan inklusif gender juga akan menciptakan sistem pembelajaran yang non-segregasi gender.

Sapindus rarak is a plant native to Indonesia. Its fruit contains abundant saponins and serves as a detergent for washing batik and baby cloth diapers. This study aims to determine the trends in the S. rarak research based on a bibliometrics and scoping review. The bibliometrics analysis was conducted by defining the search keywords, extracting publications, refining the results, compiling metadata, and mapping authors, keywords, and collaboration. There were 32 publications regarding S. rarak based on Scopus, written by 23 authors between 1992 and 2022, with 387 citations, and 201 publications with 1176 citations due to Google Scholar. Indonesia, the Indonesian Research Institute for Animal Production, and Elizabeth Wina was the most influential country, institution, and author, respectively. The research was clustered to chemistry, biology, medicine, and physics approach. Bio-prospection of S. rarak fruit extract for livestock supplementation was a hot topic. All articles reported S. rarak fruit or seed as the promising organ—no one study about the potency of leaves whereas leaves are also an abundant source of saponin. However, the potency of S. rarak leaves is still overlooked. Research on the efficacy of detergents has not been published in a highly reputable international journal, even though it has been utilized traditionally for a long time. Bibliometrics and scoping review can provide insights for further research roadmaps in this field.
