Abstract

Biodiesel is the mono alkyl esters oflong chain fatty acids derivedfrom renewable lipid sources.Biodiesel as asubstitute ofpetroleum dieselfuel has some advantages: itproduces cleaner exhaust gas, betterin lubrication, and doesnt need engine modification. This paper presents the results ofresearch concerningthe effect ofdifferentfatty acid composition ofbiodiesel onfuel quality and its performance in diesel engine.For this purpose three different fuel sample were tested, Indonesian diesel fuel (solar) as a reference,blending solar 70%- oil palm methyl ester 30%(B-3 sawit) and blending ofsolar 70%- castor methylester 30 %(B-30 castor) . All ofthese fuels are tested using Hydra diesel engine, single cylinder indirectinjection (IDI). The test results shows that the performance (peak pressure in the cylinder) ofthreefuels arequite similar, however the two biodiesel blends show lower emission in smoke, hydrocarbon, and CO atdifferent injection timings and different loads. For NOx emission, it is slightly higher. B-30 castor containsmore unsaturatedfatty acids than B-30 sawit and therefore produced higher emission bfNOx. Beside, castormethyl ester contains an extra hydroxyl group in ricinoleic acid that probably leads to lower smoke andhydrocarbon compared to B-30 sawit. It is still aquestion that CO emission ofB-30 castor higher than ofB-30sawit. Research in the effect of chemistry andfatty acid composistionof biodiesel on the emission areneeded to be able describe mechanism ofCO, hydrocarbon andNOxformationfrom biodiesel.

Abstract

The Public Prosecutor, as the representative of the State, holds dominant authority in regulating the course of criminal trials (dominus litis). The role of the Prosecutor inevitably places them in direct opposition to the interests of the Defendant. This clearly demonstrates a disparity in how the law treats the summoning of witnesses: while the Prosecutor’s witnesses are compelled by law, those of the Defendant are not equally supported or guaranteed by the legal framework. As a result, the Defendant’s right to present mitigating witnesses remains a theoretical entitlement (lex scripta) without enforceability. This research conducts a normative juridical analysis of relevant legal texts, scholarly literature, and journal sources. A significant imbalance is evident in the process of summoning witnesses those summoned by the Prosecutor aim to incriminate (a charge), while those proposed by the Defendant seek to mitigate or exculpate (a de charge). Incriminating witnesses are bound by legal obligations and face sanctions under Article 224 in conjunction with Article 552 of the Indonesian Penal Code if they fail to appear, and their testimony is considered valid evidence in court. The findings indicate that this legal imbalance significantly affects the objectivity of criminal proceedings, often leading to a tendency to disadvantage the defendant. In contrast, exculpatory witnesses are treated merely as a "right" of the Defendant, without any enforceable obligation to appear, as no legal consequences exist for their absence.

Abstract

This study investigates the use of code-mixing and code-switching in Pavolia Reine’s live streams, applying sociolinguistic frameworks by Poplack and Muysken to analyze these phenomena in a live-streaming context. Using a qualitative descriptive method, data were collected through transcriptions of her streams, focusing on identifying and categorizing instances of code-mixing and code-switching. The findings show that insertional code-mixing dominates, accounting for 97% of all cases, while alternation and congruent lexicalization represent 2% and 1%, respectively. This reflects the bilingual and multicultural environment of Hololive Indonesia, where Indonesian speakers frequently incorporate English and Japanese to reach broader audiences. Inter-sentential switching is the most common form of code-switching at 53%, followed by intra-sentential switching (29%) and tag switching (18%). These patterns demonstrate how linguistic strategies are employed to connect with local and international viewers, highlighting the multilingual backgrounds of the speakers. Overall, the study underscores the complexity and fluid integration of multiple languages in online streaming, illustrating how digital communication reshapes linguistic practices in real time

Abstract

The e-learning system is currently a hot topic of conversation considering the Covid-19 pandemic situation which has hampered the teaching and learning process in various countries. XYZ University as one of the best technology universities in Indonesia has used the e-learning system long before the pandemic. Therefore, this research was conducted using quantitative methods to determine the factors that influence system success in the XYZ university e-learning system in hope that this research can be a benchmark as a effective solution. This study uses several literature studies including e-learning, and knowledge acquisition. Data analysis was carried out using the SEM method using the SmartPLS 3 application. There were 6 independent variables, namely information quality, system quality, service quality, system usage, user satisfaction, and knowledge acquisition. The dependent variable is system success. From the results of the questionnaire distribution, 385 respondents were obtained from XYZ university undergraduate students who are still actively studying out of a total of 418 respondents. A total of 224 respondents were male and 194 respondents were female. This study proposes 12 hypotheses that have 11 accepted hypotheses and 1 rejected final results. This research contain indicators per variable that used for the questionnaire also several data analysis process was served. The results show that the knowledge acquisition is positively influenced by system quality but not significant and the information quality have a significant positive effect on the knowledge acquisition. There are limitations in this study, where the selected respondents are limited by the researcher cause of some access to respondents. Further research can be conducted on students from various majors so that they can gain different perspectives for more concrete evidence. Further research can be carried out using other variables that support proving the factors that influence the success of the system using the DeLone and McLean models.
