The advance of technology has affected many aspects of people’s lives. One field that also has been greatly affected by this advancement is Education. There are lots of online learning platforms that emerged in the past 2 decades. Khan Academy and IXL are two favourite examples of those platforms that are being used to help students learning Mathematics and Science. DeltaMath, although not as famous, is also of the platforms that are available and can be used to help students learning Mathematics. This study examined the impact of DeltaMath toward students’ Mathematics learning outcomes. There are 56 samples in total that are divided into 2 group of 28 students. One group is the group of students who are introduced to and are using DeltaMath as supplementary resources in their learning and the other group consisted of students that didn’t use the DeltaMath in their learning. Main findings show that: 1. The average score of the final exam of group who used DeltaMath is higher than the group of students that didn’t use DeltaMath. 2. Students who solved more than 150 questions in DeltaMath performed better in the final exam than most students, their average is 7 points higher compared to the average of all students. 3. There is no significant difference between group that are using DeltaMath compared to group of students who didn’t use DeltaMath. There are still few publications related to DeltaMath, unlike Khan Academy and IXL, thus, this study hopefully can contribute to the research of the impact of using DeltaMath.

Ensuring the security of people's personal data is the government's responsibility, in accordance with Article 79 paragraph (1) of the Population Administration Law. The sale of government-held documents is one example of how data can be accidentally deleted. If a person's passport information is not adequately secured by the institution responsible for implementing the law, then the person can request compensation as described in Article 2. By using a legal and conceptual approach, this research is included in the category of normative juridical research. As far as legal resources are concerned, there are two main categories: primary and secondary. We use a descriptive normative analysis approach to sort legal information into categories based on the topics discussed. The findings of this research highlight the responsibility of supervisory institutions in ensuring the security of individuals' personal information and the accountability of the state or government in accordance with the Population Administration Law and prevention initiatives. Some possible suggestions to protect people's rights include a more transparent compensation process and clearer regulations prohibiting the sale of personal data.

Cases of intolerance are often found in Indonesia, causing religious harmony to fade, for example cases such as the rejection of the establishment of a house of worship at the Indonesian Baptist Church in Tlogosari, Semarang or cases of brawls between teenagers. Due to this phenomenon, the concept of religious moderation was promoted to increase the sense of harmony between religious believers. Religious moderation is a moderate sense of religion, no less and no more. This research aims to determine the influence of religious moderation on the reality of religious harmony in Semarang, especially in the views of the younger generation (aged 16-35 years). The author uses quantitative methods. In this research the author used a simple regression equation method. This research shows a positive value for the influence of religious moderation on religious harmony of 40.1%. This index shows that the influence of religious moderation is quite strong in building religious harmony in the view of the younger generation

Social Media Instagram is a very famous application that is used by various audiences. Instagram is a very famous social media platform and is used by all audiences. One of them is in generation Z, because this platform has many features that can support users, for example sharing information or content and even being able to interact with friends, or even sharing stories and photo posts. So Instagram is very suitable to be used as social media to introduce people. Just like researchers took research to analyze the existence of Instagram content that is effective in attracting generation Z. Because in this case radio Elbayu is not yet known to generation Z. radio Elbayu only recommends radio that still uses AM frequencies. And the listeners are only elderly, the Z generation doesn't know or understand it yet. So with the Instagram platform that can create this content it can attract or add new followers. So that in this way we can still maintain the unique characteristics of Elbayu radio, namely radio broadcasts with AM frequencies and also Elbayu radio can keep up with the times by creating content on Instagram so that generation Z is more interested and gets to know Elbayu. Namely, the content is about Gresik and Surabaya, such as recommendations for tourist attractions, historical places, and much more

This article aims to look at the phenomenon of educators in the use of learning methods, because educators are one of the final factors in the success or failure of learning carried out in schools, so by using a variety of teaching methods students are expected to achieve maximum learning achievement. One of the learning methods that can be applied in Akidah Akhlak learning is the Uswah Hasanah method. This method as a method is used to realize educational goals by giving good exemplary examples to students to be in line with the values of the Qur'an and Sunnah. The purpose of this research is to explain the planning, implementation, evaluation, and supporting and inhibiting factors. The type of research is descriptive qualitative field research. Descriptive type is a research intended to collect information about the status of an existing symptom, namely the state of the symptom according to what it is at the time the research is conducted. The results showed that the planning of the Uswah Hasanah method in Akidah Akhlak had been made by educators and had been applied in the learning process. The planning is in the form of a teaching module. The implementation has been carried out in accordance with the planning made in the teaching module, although the implementation is not in accordance with the actual theory and not all steps of using the method are carried out by Akidah Akhlak educators. Evaluation of the implementation of this method is carried out continuously during learning.

The mother is the leader figure in a family who is responsible for managing the family's healthy food needs. Knowledge regarding hygienic food among PKK mothers in Papahan Village, Tasikmadu is still limited, because many of them come from underprivileged families and have less educational background, so basic knowledge from the family is not optimal (less attention is paid to it). This community service activity aims to provide understanding to PKK women about healthy and hygienic food, provide counseling to PKK women about the characteristics of healthy and hygienic food and provide awareness to the public not to buy food carelessly. The outreach method is carried out using the lecture method and explanations regarding healthy and hygienic food and contamination or bacterial contamination in siomai sauce from traveling sellers using posters and power points.

The conclusion of this community service activity is that PKK mothers can find out the benefits of healthy and hygienic food for the body and PKK mothers are aware to be more careful in buying food outside so that family health, especially school children, is more secure and mothers PKK mothers understand how to choose healthy and hygienic food for their families.  

Technological developments have given rise to various new innovations to make it easier to fulfill human needs, one of which is online lending and borrowing services. Shopee Pinjam or SPinjam is an example of an online loan service that includes standard clauses in the contract agreed by the debtor. The problem that often occurs due to easy access to borrowing and lending through SPinjam is misuse of data for other people's needs or what is known as name lending. The purpose of writing this research is to find out how legal accountability is given to the parties. The research method used is a normative research method, with deduction analysis techniques. The results of this research indicate that the name borrowing agreement made between the name borrower and the name giver is an oral agreement that has weak legal force. This agreement is only binding on the party making it without any intervention from SPinjam. Legal responsibility regarding the repayment of SPinjam is an absolute responsibility that must be fulfilled by the debtor who agrees. The name borrower cannot be burdened with legal responsibility because the name borrowing agreement has not been specifically regulated in positive law in Indonesia so that the solution to the problem that can be done is by deliberation between the name borrower and the name giver.

One example of rapidy developing technology is gadgets. This journal aims to understand the impact of gadgets in the socio-emotional development of young children. The authors of this journal employed a literature review research method. The use of gadgets in early childhood has a significant impact on their socio-emotional deveploment, both positive and negative, depending on the duration, content, and contet of usage

War conflict is something that is difficult for countries to avoid. For example, conflicts between Israel and Palestine occur repeatedly, but the realization of international accountability is not yet in accordance with existing regulations. The events that resulted in casualties in the war must be held accountable by Israel as a State, as well as the individuals involved. As a result of these actions, the perpetrators of war crimes must be held accountable under international law. The research method used is normative juridical research, namely by using library materials, by studying and examining the regulations governing international criminal law, both regulations from the Indonesian government and the constitution issued by the Rome Statute. Based on the results of research and discussion, it can be seen that the mechanism for enforcing international criminal law based on the 1998 Rome Statute is carried out through several stages, namely submission of a case by the state party, investigation and prosecution, trial, decision making, finally appeal and review.

Parental divorce significantly impacts early childhood development, especially in the digital age. Children may experience low self-esteem, difficulties in building relationships and socializing, aggressive behavior, learning difficulties, value confusion, deviant behavior, and loss of trust.Addressing these impacts requires digital parenting, open communication, moral education, and collaboration with educational institutions. Parents and stakeholders must understand the effects of divorce to provide appropriate support for children's healthy and happy growth. A qualitative case study at TK Negeri Bung Karno involved interviews with PAUD teachers and parents, as well as classroom observations. The findings showed that children tend to imitate negative parental behaviors. Through gradual guidance, children learned to distinguish between good and bad behavior, showing progress in emotional control, social interactions, and setting positive examples for peers.

This research aims to find out how many fathers are involved in caring for early childhood children in the Surabaya area. The background of this research is to look at the phenomenon of fathers' lack of involvement in child care, resulting in some children behaving in fear, lacking self-confidence, speaking harshly, and not being able to control their emotions. This research is a quantitative descriptive research with a survey method. The subjects of this research were fathers who had young children in the Surabaya  sub-district area. Respondents in this study totaled 332 fathers. The research results show that as many as 84% ​​of fathers have high involvement in their children's care in Surabaya  Village. However, based on the data, 42% of fathers are still busy with their activities when they are with their children and as many as 46% of fathers are still not close to their children, such as kissing and hugging their children. Therefore, it is necessary to provide training to fathers on how to care for early childhood children which includes aspects: Interaction, giving an example, accompanying, supervising, providing warmth and meeting the child's needs.  

This article examines a potential solution to the well-known Travelling Salesman Problem (TSP), which is classified as an NP-hard problem. We also provide a theoretical synopsis of several approaches that have been employed to tackle this problem. A prominent example of a combinatorial problem is the traveling salesman problem (TSP). To address the fundamental PSO algorithm's premature convergence issue and stagnation behavior on TSP, a scout characteristic-based PSO algorithm is suggested.We address Particle Swarm Optimization (PSO), a member of the evolutionary methods class, and outline the methodology for applying PSO to the TSP. Among population-based metaheuristic optimization methods, Particle Swarm Optimization (PSO) is one of the most widely used. Scientific domains such as engineering, chemistry, medicine, advanced physics, and humanities have all effectively employed PSO. Numerous theoretical and empirical results on the convergence and parameterization of PSO versions have been produced as a result of the method's extensive investigation since its introduction in 1995. Hundreds of PSO versions have been developed. It is well recognized that population size has a significant impact on the effectiveness of metaheuristics; nevertheless, no comprehensive research has been done on the appropriate selection of PSO swarm size to date.Through the application of this approach, we examine the effects of various control settings. The ideal solution and the quality of the solution are contrasted.    

Violence is usually carried out by someone against another person for a reason, for example because someone is very annoyed or angry with another person so that he commits violence intentionally or not. The research method used is descriptive qualitative. Data collection techniques are observation, interviews and documentation. The results of the research show that when violence begins, such as shouting and pinching children, this continues to include hitting and throwing things at children. Meanwhile, children who experience verbal violence such as verbal abuse or insults experience conditions related to feelings. Children will feel insecure, close themselves off, feel inferior and overthink

The Covid that hit Indonesia has made everything we do change drastically. There are many rules in our daily lives such as wearing masks, washing hands and maintaining distance. In addition, all areas of life are also affected, the most affected is in the field of education. The impact of covid 19 is certainly very influential for schools, even universities because online learning is carried out, this is certainly very impactful. In addition to having a great impact on online learning, there are also obstacles in implementing it, for example, students do not have mobile phones, or teachers are not proficient in using IT-based technology and many more. The impact of online learning is very diverse, the most affected is elementary school, because it is in elementary school that we start everything, both lessons and socializing. The impact of online learning, especially at the elementary level, is that students become lazy in learning, students are bored while studying, the lessons learned do not enter the brain due to lack of explanation by the teacher, student association becomes less and so on.

Ferns are low-level plants whose distribution is quite wide and are often found on the campus of UIN Sunan Gunung Djati Bandung. The aim of this research is to determine the calcification and relationships of ferns that live in the campus area using direct exploration methods by observing their morphological characteristics. The data from morphological observations is then processed into a dendogrm so that relationships can be identified and read using the similarity index formula. The results of this research show that 2 divisions of ferns were found, namely pteridophyta and traceophyta. In the pteridophyta division, 1 class, 2 orders, 6 families and 9 species were found. Meanwhile, in the traceophyta division, 1 class, 1 order, 1 family and 1 species were found. The results of the kinship analysis show that the 10 species of ferns can be divided into 2 large groups based on 16 morphological traits. The relationship between species is measured using the Sorensen similarity index, which shows that several species have a relationship that is very close (≥ 75%), close (51-74%), not close (26-50%), and very not close (≤ 25%). For example, Pityrogramma calomelanos and Adiantum capillus are very closely related with a similarity index of 87.5%, while Pyrrosia piloselloides and Phymatosorus scolopendria are not closely related with a similarity index of 43%.

Leadership style can be defined as a collection of a person's behavior that aims to change and influence the minds of other people so that they are willing to follow the instructions and directions given. This research is a type of qualitative research that uses a descriptive approach. The aim is to explain and describe information obtained from the field as data in research. The location of this research was at SMKS St. Nahanson Parapat Sipoholon, the research subject is the principal at SMKS St. Nahanson Parapat Sipoholon. The data analysis method used refers to the theory of Miles and Huberman, which consists of several steps as follows: 1). Data Collection: Researchers collect data through interviews, observation and documentation. 2). Data Reduction: Researchers carry out selection returning to the data that has been collected at the data analysis stage. 3). Data Presentation: The reduced data is presented by the researcher at this stage. 4). Drawing Conclusions: Before drawing conclusions, the researcher double-checks the data that has been collected. Leadership is the ability and readiness of an individual to influence, encourage, invite, guide, mobilize, and if necessary force others to act in achieving organizational goals. Situational leadership is a leadership approach in which the leader's behavior is adapted to the varying conditions and situations of each subordinate. Indicators that influence situational leadership include: (a) the telling dimension, where the leader gives clear instructions when assigning; (b) selling dimension, which involves two-way communication between leaders and subordinates; (c) participating dimension, which includes assigning tasks and responsibilities to subordinates and supporting leaders in carrying out these tasks; and (d) the delegation dimension, where the leader gives authority to subordinates to act independently. At St. Mary's Vocational School Nahanson Parapat, the situational approach adapts leader behavior to specific conditions and subordinate needs, with four main styles, namely telling, selling, participating, and delegating. Situational leadership has been implemented with examples of implementation by the Principal practicing a telling approach in exam preparation, using selling in discussing new teaching scheduling, and participating in Prakerin planning. However, the delegating style is less applied because the Principal tends to control all aspects of decisions and tasks. In practice, situational leadership at St. Nahanson Parapat faces several obstacles, including the school environment and staff characteristics, which influence the effectiveness of implementing this leadership style. These obstacles require special strategies to overcome them, so that situational leadership can be more effective and adapt to existing situations, so that organizational goals are achieved optimally.

: The aim of this research is to find out how legal protection is for minors as recidivists of criminal acts of theft and the causal factors in Gorontalo City. The method used is an empirical approach based on field facts, then analyzed descriptively qualitatively. The research results show that legal protection for children who are recidivists is provided during the legal process, starting from the investigation, arrest and detention stages. The legal process is carried out in accordance with the provisions of the SPPA Law, and prioritizes the needs, development and growth of children, both physically, mentally and socially. The implementation of legal protection for children who are in conflict with the law, especially for repeat criminals or recidivists, is carried out in the same way as for first-time perpetrators of other criminal acts, but the only difference is that diversion efforts are not applied to those who are recidivists. The protection carried out by the police is to fulfill children's rights in every ongoing legal process; The investigation prioritizes a family atmosphere; and Separate Detention. The cause of children becoming recidivist perpetrators of the crime of theft in Gorontalo City is environmental factors; Economy problem; There is leniency in punishment and lack of effective coaching; and Factors of legal awareness and parental negligence. Therefore, in implementing legal protection for children who commit criminal acts, especially for recidivist perpetrators, law enforcement officers are expected to pay attention to the psychological and social conditions of children, but still prioritize providing a deterrent effect so that perpetrators are afraid to repeat their crimes. These efforts include, for example, implementing existing legal procedures by fulfilling all children's rights, but still carrying out repressive action by providing sanctions as regulated in statutory regulations, and not imposing diversion on perpetrators who repeat criminal acts. Apart from that, the government and especially parents pay as much attention as possible to ensuring life for children, so that they do not become perpetrators of criminal acts such as theft. This is because children are sometimes forced to commit these crimes due to their needs not being met properly, or even due to pressure from other parties.
