Abstract
The BNCT in-vitro test using a microtube irradiated on the neutron beam of the RSG-GAS beam tubes has been simulated. The simulation was performed using a PHITS computer code by modeling a microtube containing boron solution which was placed 5 cm in front of the beam tubes. Inside the beam tube was installed a beam shaping assembly (BSA) using 80 cm of MgF2 as a filter to reduce fast neutron and gamma fluences. Microtube containing 1.5 mL of boron solution with boron enriched 10B of 90%. The microtube dose i.e alpha dose, 7Li dose, proton dose, and gamma dose were calculated for each variation of boron concentration from 0.1 - 20 ppm. The simulation of microtube containing 1 ppm boron solution shown that irradiation of BSA-S5 neutron beam can be produced at a dose of 20 Gy with the shortest irradiation time of 2.5 hours.

Abstract
The basic functions of communication are entertainment, amusement, deliver public opinion, social control, critics and educate (provide knowledge). Delivering opinion has the same meaning as creating a dialogue forum among the communities and between the communities and the government. This community service discuss the socialization of “the causes of the khilafian (opinion differences) in islamic communication” which is formed in speeches and discussions as one of the islamic dakwah to understand, believe and to practice Islamic syari-ah and aqidah. Khilafiah litterally means argue, different or dissagree. Basically, the ulama fiqih opinion differences happen because of two things, first: principals differenciation of the legal position, whether it can be taken as the consieration to determine the law or not. Second, principals differentiation about language rules in understanding a nash (Al-Qur-an and Al-Hadits). Therefore in this socialization the writer delivers the causes of the khilafiyah or opinion differences of Ulama Fiqh. This socialization aims to make moslem people understand, respect, appreciate and accept the opinion differences in carrying out the worship rules in Islam.

At the age of adolescence, namely the age range of 15 to 18 years adolescents will experience the first puberty, even some children experience puberty more quickly, which is around 10-13 years. In puberty, there is a strong urge that comes from within the individual to know something that he had never known. Circumstances like this that encourage adolescents in this case to try new things in life, including free sex (free sex). Sexual activity via mobile phones has now mushroomed in the community. Do not know the beginning of when it began, but certainly there are many who know if sex can be done via cellular phone. The activity of having sex through a cellular phone is called phone sex. Telephone sex (Phone Sex) is a type of virtual sex that refers more to explicit sexual conversations that occur between two or more people over the telephone especially when one participant or sex partner masturbates or performs sexual fantasies. Phone Sex (PS) is a sexual activity carried out by listening on a cellular phone. Providing sex education for children is the responsibility of all parties: parents, teachers, the community and the government. It becomes a preventive measure that can be applied early, by providing sex education for their children, especially in Early Childhood Education

Abstract
This is a community service related to the development of economic community through socialization on muamalah principle and the prohibition of maghrib (maysir, gharar and riba) in the daily transaction. Nowadays, some people in Indonesia have begun to care about the dangers of riba and its impact on the economy. Muslims have believed that riba is haram. Some of them certainly can define as well as interpret the term of riba, but not for maysir and gharar. According to the perspective, Islam always encourages the practice of good muamalah principle and forbids maghrib. Ironically, there are still many ordinary people do not understand the general rules of maghrib. In returning the daily transaction to avoid maghrib, it is necessary to learn deeply about this subject. For this reason, there is a need for socialization to the wider community to increase good understanding of the maghrib and get literacy about sharia transaction well and certainly can be implemented in the daily transaction of community in Indonesia.

Abstract
Intra-School Student Organization (OSIS) is a means of developing students interests and talents in the schools internal environment. The existence of the student council can be beneficial for schools and the community. OSIS is also a major component of the pioneering schoolfor developments in the school. The problem is that many student councils do not show their existence as a driving force in the development of schools and students. The student council vacuum is more due to the low understanding of management and leadership concepts, so that potential members cannot be managed properly. This community service activity is carried out by providing training and program assistance for 1 month. As a result of this activity is the increasing existence of OSIS in schools and is beneficial for students and the community as a forum for discussion in terms of increasing the existence of OSIS and contributing to human development.

Abstract
The idea of the concept of Wasathiyah Islam (moderate Islam) reappeared in the High Level Consultation (Summit) of World Muslim Scholars and Intellectuals at the Bogor Palace, 1-3 May 2018. Wasathiyah Islam is perceived as a perspective that understands the position of Islam between two extreme opposite points: Fundamentalist and radical on the one hand, and liberal and permissive on the other. Women are the party most defeated by Islamic fundamentalists and most disadvantaged in the application of rigid Islamic sharia in various places in the Islamic world. In connection with concept of Wasathiyah Islam, women have monitoring ability that can promote constructive dialogue and provide understanding, both in the family and in the community. Therefore, women need to be equipped with a full understanding of the concept of Wasathiyah Islam, because misleading understanding can foster religious radicalism on the one hand, and permissive attitudes will dwarf the understanding of religion on the other. The method used in this counselling includes several stages: 1) survey; 2) module making; 3) counselling; 4) interactive dialogue; 5) evaluation. The results of the counselling showed that after the training, participants enhanced their knowledge about the concept of Wasathiyah Islam. They began to realize that they had an important role in instilling a correct understanding of Wasathiyah Islam towards their families and communities.

Abstract
Introduction: Mental conditions in children and adolescents today are very alarming. This condition is characterized by an increasing number of children and adolescents who experience psychosocial problems such as depression, substance abuse, crime and others. The impact of depression on adolescents can arise, among others, performing various actions such as non-suicidal self-injury (NSSI), attempted suicide, even to death from suicide. Biopsychosocial factors in NSSI patients are very important to be traced because they play a role in the etiology, course of the disease, management and prognosis of the patient. Case report: A 13-year-old teenage girl with a chief complaint of self-injury a year ago. The patient injures himself with a cutter or razor on his arm which is getting done more and more frequently so that there are more injuries to the patients arms and thighs. But apparently many friends of patients at school who do the same thing. Biopsychosocial approaches are applied to patients and their families, including the provision of psychopharmacotherapy and psychotherapy drugs to patients so that children can be independent and adapt to the environment. Family education and therapy is carried out so that the family can support the therapy process. Conclusion: The biopsychosocial factor approach to NSSI is satisfactory.

Abstract
This study discusses the optimization of production plans using a dynamic programming through a case study on the one of a convection company. Fluctuating demand requires the convection company to implement a strategy to control the production process so that there are no shortages or excess products. The purpose of this study is to find out the total minimum costs with respect to school uniform production plans for the monthly-period demands of next one year. The initial step used in the production planning is by estimating the monthly-period demands of products for the next one year based on the monthly-period demands of previous 3-years. The implementation of dynamic programming brings to break down the case problem into 12 stages with respect to the monthly periods of the next one year. This study results in the total minimum cost of production plan for the next twelve months. Therefore it convinces that the production planning through dynamic programming is able to maintain the existence of a convection company due to its significant advantages of the approach for future production planning.
