This media aims to foster moral expertise, moral sentiments for preventing drug abuse, and moral actions in drug prevention within the context of Classical Guidance. The development of Si Mirasantika Android-based media involved a structured approach. The media's content is organized into three main parts: opening, contents, and closing, which encompass sections such as introduction to drugs, factors of drug abuse, and methods of cure. Feedback and revisions were conducted based on trial data analysis, addressing aspects including subject matter, auxiliary information, affective considerations, interface, navigation, pedagogy, and robustness. Evaluation was performed by expert media validators, media design experts, content/material experts, and target trials. The results indicate that the Si Mirasantika media is suitable for use by students at SMK Negeri 1 Brondong Lamongan, as validated by media experts, design experts, and content/material experts. The media received high validity scores, with the media design expert validation at 90.67%. Feasibility tests in small and medium classes showed positive outcomes, with effectiveness tests in the large class achieving a very effective score of 80.07%. These results support the utilization of Si Mirasantika as a supplementary resource in Classical Guidance, enhancing students' knowledge and understanding of drug abuse prevention. Keyword : Mirasantika, Android, 4d INTRODUCTION SMK Negeri 1 Brondong is the only state vocational school in the north coast of Lamongan, which is located in Mboho Hamlet, Tlogoretno Village, Brondong District, Lamongan Regency. The people in coastal areas, actively working in the fisheries sector. This condition makes some people who live in the northern coastal route work as fishermen.1 Because it is located in a coastal area, most of the students come from the sons and daughters of fishermen2. 1 Fatik Khussurur, “Pengembangan Tempat Pelelangan Ikan Dan Prasarana Perikanan Samudera Di Brondong Kabupaten Lamongan: Tema Analogi Biological” (Universitas Islam Negeri Maulana Malik Ibrahim, 2014). 2 Wiwik Widyo Widjajanti et al., THE MEANING OF CULTURAL COASTAL COMMUNITY AS BASIS OF THE OPEN SPACES CONCEPT IN FISHERMEN SETTLEMENTS, International Journal of Humanities, Religion and Social Science, 2019; Irzum Farihah, “Perilaku Beragama Perempuan Ngorek Di Pesisir Lamongan,” Sawwa: Jurnal Studi Gender (2019). mailto:gnscntr@gmail.com mailto:atiqoh@unipasby.ac.id mailto:suhari@unipasby.ac.id Volume 8, Number 3, November 2023| 372 With so many fishermen, the spread of drugs/narcotics, including Koplo pills, is spreading massively3. Illegal drugs have been circulating in East Java, especially in the Lamongan Regency. Based on the result of research at the Narcotics Research Unit of the Lamongan Police in cases of drug abuse from 2012 to 2014, data obtained on an increase in the number of suspects and distribution of illegal drugs.4 For example, in early 2016, the police arrested Koplo pill dealers with evidence of 190 Koplo pills5. This happens because, when they go out to sea to catch fish using a boat owned by the ship's owner, when they are on the high seas they are sometimes given koplo pills such as the Carnopen type, free of charge to increase the tripping effect or increase their work power. The more often they use these drugs, the more addictive effects it will bring. The negative consequence is that they experience dependency while on land or no fishing6. When they are not at sea, they will look for these prohibited drugs from dealers or Koplo pill providers which are rife in circulation in the coastal areas of Paciran and Brondong.7 Drug abuse usually begins with the cosumtion of cigarettes. This smoking habit seems to have become a normal thing among students today. From this habit, the association continues to increase, especially when the student joins the circle of people who are already drug addicted8. Initially tried, then experienced dependence. So that students need information on strategies and abilities to avoid the dangers of drugs. One of the efforts to overcome the dangers of drugs is to carry out program that focuses on school-age children. Many efforts have been made by schools to reduce the spread of drugs. Among them are counseling about the dangers of drugs, and information through various media, for example films about the dangers of drugs. However, the results have not been maximized because they have not been able to foster a feeling of fear of the effects of drug abuse and they feel they are not involved in the prevention process. One way to disseminate this information can be done through service activities in Counseling Guidance.9 To help spread knowledge about drugs in the school or community environment, it is necessary to have a technological media that is developing and popular at every level of society, both in terms of age and profession. In fact, in 2019, an Android-based information 3 Jurnal Syarif et al., “Kelima , Program Pelatihan Ketrampilan Psikososial : Program Latihan,” Penyuluhan Bahaya Penyalahgunaan Napza Bagi Pelajar Dan Remaja (2018); Humas BNN, “Pencegahan Penyalahgunaan Napza,” BNN. 4 Ahmad Faizal Rusdianto, “Penanggulangan Tindak Pidana Peredaran Obat Keras (Daftar G) Jenis Carnophen Di Kalangan Nelayan (Studi Di Polres Lamongan)” (Brawijaya University, 2015). 5 “Pengedar Pil Koplo Di Lamongan Dibekuk Polisi - Surya.Co.Id,” accessed December 27, 2023, https://surabaya.tribunnews.com/2016/02/11/pengedar-pil-koplo-di-lamongan-dibekuk-polisi. 6 Chinyere Kemet, Emily Hill, and Hui Feng, “Fishing for Drugs,” ELife, 2022; James R.

Volume 8, Number 3, November 2023| 373 media has been developed about the Types of Drugs at the National Narcotics Agency for East Kalimantan Province. This Android-based media is dissemination of information and assists socialization regarding the adverse effects of drug abuse. The media has not been used in Classical Guidance activities with all guidance procedures up to the evaluation and follow- up stages, so that it can require the involvement of students in preventing drug abuse, especially in the social environment.10 In counseling guidance activities on drug materials, it is also necessary to have a fun guidance medium for students to get to know the types and forms of drugs, their dangers and the impacts of criminal law. This guidance media can be in the form of disseminating information or fun games, so that it can provide knowledge that is not just for them to know or understand but also continues on feelings, namely aspects of emotion that must be able to be felt by someone to stay away from narcotics and end in action, namely able to understand what to do to prevent drug abuse The results of closed interviews with the counseling teacher and students regarding the initial conditions of Classical Guidance on Drug Abuse Prevention Materials, obtained data that the counseling teacher had used media in the form of videos and Powerpoint Slides. The majority of BK teachers and students need media development to help them understand Classical Guidance material more easily and flexibly. Students think that the guidance media currently used cannot help understand the material, and 93% of students and 100% of counseling teachers need Android-based guidance media.11 Media is an intermediary from sources of information to recipients of information.12 As a tool, the media has the function of arousing students' interest in following the learning process in a focused manner. In addition, the learning media displayed can motivate students to study more diligently. It is undeniable that learning media also has psychological influences on students. Learning media users really help student activity in the learning process and make it easy for teachers to convey messages and content of learning material. That means that students' learning activities with the help of the media will produce better learning processes and outcomes than without media assistance. 13 Android-based information media about the Types, Dangers and Methods of Curing Drug Abuse in schools really need to be developed for use in Classical Guidance activities. With this media it is hoped that students will have moral knowing, moral feeling and moral acting in preventing drug abuse starting from the school environment. This development research is about the idea of how to develop fun guidance media in its implementation in Classical Guidance to prevent drugs, especially the Koplo pill type, by involving students directly in their learning experience, whenever and wherever they are flexible. 10 Ibid., page 38-39 11 Lecturers and Artists, Interview with Counseling Guidance Teacher at SMK Negeri 1 Brondong Lamongan, 13 December 2022 12 D R H Wina Sanjaya, Penelitian Tindakan Kelas (Prenada Media, 2016). 13 Novita Dwi Lestari, Ruswandi Hermawan, and Dwi Heryanto, “Pengembangan Media Pembelajaran Menggunakan Powtoon Untuk Pembelajaran Tematik Sekolah Dasar,” Jurnal Pendidikan Guru Sekolah Dasar 3, no. 3 (2018): 33–43. Volume 8, Number 3, November 2023| 374 Method Research is development research. This media product development model refers to the 4-D development model formulated by Thiagarajan, et al.14 The development stages are translated into 4 steps, namely: (1) the definition stage (Define), (2) the design stage (Design), (3) the development stage (Develop), and (4) the results dissemination stage (Disseminate). The initial stage is the definition and design of the media. In the definition stage, this media uses the Lollipop version of the Android base. The basic competency developed is Social Responsibility Awareness with Drug Abuse Prevention Material. The program component is responsive service with Classical Guidance service activities. The developed media is equipped with sound, images and information that can help visualize the material contained in the media. The design stage starts with the design of the contents of the media. The initial draft of the guidance media includes: 1) Opening, (2) Contents (Materials) and (3) Closing. The Opening section consists of the Preamble, Homepage and Introduction. The Contents section consists of Introduction to Drugs, Factors of Drug Abuse and Methods of Cure, and Impacts of Drug Abuse. The closing section consists of Post Test Quiz, Project Based Assignments and Game Bonuses. The initial draft of the guidance media to be developed is called the initial draft. The initial draft of the media is arranged in the form of a storyboard, alpha testing is carried out, namely validation includes 1) Subject matter, namely whether the material provided is in accordance with the initial objectives of making the program and the depth of the material is in accordance with the level of students who will use the product and whether it is in accordance with goal to be achieved. Is the content structure appropriate and the material presented in the product is appropriate? (2) Auxiliary information, namely additional information that is not directly related to the material, such as introductions, instructions, assistance, and conclusions. (3) Affective considerations, namely how this product can motivate students to learn more. (4) Interface, because product appearance is very important, learning multimedia developers must pay attention to writing text, animation and graphics, audio, and video. (5) Navigation, navigation must be made as easy and clear as possible so that users have no difficulty accessing the program. Navigation must be consistent. (6) Pedagogy, things that must be considered are methodology, interactivity, cognitive capacity, cooperative learning, learning strategies, user control, questions, answering questions, quality of feedback, and level of mastery of the material. (7) Robustness or product resistance is needed. Programs should never fail or have errors.15 After that, beta testing was carried out to test the feasibility and effectiveness of the media by students. The validation was carried out by experts who were competent in understanding classical guidance media, in this case, graduate school lecturers. As for the validation of the material for Classical Guidance, it is carried out by the counseling teacher with the specifications of a Bachelor of Counseling Guidance graduate and has carried out guidance 14 Dian Kurniawan et al., “PENGEMBANGAN PERANGKAT PEMBELAJARAN DENGAN MEDIA SCREENCAST- O-MATIC MATA KULIAH KALKULUS 2 MENGGUNAKAN MODEL 4-D THIAGARAJAN,” Jurnal Siliwangi (2017). 15 Surakhmad Winarno, “Metodologi Pengajaran Nasional,” Jemmars, Bandung. TT (1979). Volume 8, Number 3, November 2023| 375 activities for 5 years. The purpose of this validation is to determine the feasibility of the development guidance media. The assessment used to determine the validity of the media uses the criteria for the aspects of subject matter, auxiliary information, affective considerations, interface, navigation, pedagogy, and robustness. Media assessment criteria using a Likert scale. The Likert scale is a number of positive or negative statements regarding an attitude object. The main principle of the Likert scale is to determine the location of a person's position in a continuum of attitudes towards attitude objects ranging from very negative to very positive.16 The criteria are divided into 5 categories, namely 5 very very very valid/very feasible/very effective; 4 very valid/very feasible/very feasible; 3 valid/decent/effective; 2 less valid/less appropriate/less effective; and 1 is very less valid/very less feasible/very less effective. After the data is obtained, then to see the weight of each response and calculate the average score with the following formula: �̃� = ∑ 𝑥 𝑛 Information: �̃� : average score 𝑛 : number of appraisers 𝑥 : total score of each The percentage of results can be calculated using the following formula: Hasil = total score obtained maximum score x 100% The validity category is based on the following criteria:17 Table 1 Media Validity Criteria Persentase (%) Kategori 81 – 100 Very Valid 61 – 80 Valid 41 – 60 Fairly Valid 21 – 40 Invalid 0 – 20 Strongly Invalid Arikunto explains that research instruments are tools or facilities used by researchers in collecting data so that their work is easier and the results are better, in the sense that they are more accurate, complete and systematic so that they are easier to process. Data collection techniques used in this study were closed interviews with check lists and questionnaires. Structured interviews were used to collect data regarding the techniques and media used by the counseling teacher in the Classical Service on Drug Abuse Prevention materials, and to determine the need for Classical Guidance media. Questionnaire is a data collection technique that is carried out by giving a set of questions or written statements to 16 Z Ayob, A Wagiran, and A A Samad, “Potential of Tissue Cultured Medicinal Plants in Malaysia,” J Teknologi 62 (2013): 111–117. 17 Suharsimi Arikunto, “Metode Penelitian,” Jakarta: Rineka Cipta (2002): 71–89.
