Tujuan kegiatan Pengabdian Kepada Masyarakat (PKM) adalah membangun diskursus mengenai pemodelan matematika sebagai pendekatan untuk memahami dan membuat keputusan tentang fenomena radikalisme, terorisme, dan fanatisme. Pendekatan ini digunakan untuk mendorong para pihak (khalayak sasaran) agar dapat menyorot kepentingan dan relevansi matematika dalam menjawab berbagai persoalan terkait. Pendekatan ini juga membantu dalam transfer keterampilan, termasuk kebiasaan berpikir yang menyebar ke dalam berbagai disiplin ilmu. Perlu diperhatikan bahwa model matematika pada prinsipnya dapat diterapkan juga pada skenario kriminal dan teroris dalam populasi yang homogen seperti yang terjadi dalam kasus di beberapa negara Tim PKM FKIP UNTAN mengajak khalayak sasaran untuk secara bersama-sama mengenal pemodelan matematika sekaligus sebagai suatu bentuk laporan akuntabilitas untuk memasukkannya kepada stakeholder.

The fact that the village is the recipient of conditional social assistance for the poorest families in Tamansari District, Tasikmalaya City in 2019 is a component of great concern in Setiawargi Village. Food security, particularly during the current pandemic, is one of the issues associated with the community in the village. There is concern that this will further worsen the household food security situation, particularly for sustainable farming households. In Depok, Setiawargi Village, the alternative offered by external parties, namely the Siliwangi University Community Service Team through the Food Security Scheme, is to assist in the procurement of organic vegetable banks to target farming group partners and women's farming groups. The implementation activities to be carried out include: 1) observation of the community's initial needs; 2) preparation of seeds and post-observation equipment; (3) Home yard optimization counseling; (4) Introduction to organic vegetable banks; (5) Organic vegetable packaging, design, and marketing training; and (6) Organic vegetable planting assistance. The results of this activity suggest that the local community is passionate about the concept of an organic vegetable bank. The issue, however, is that the use of organic fertilizers has not been maximized so far because of the long-term results obtained. Other external parties, such as farm extension workers who work in synergy with the community service team, must continue to assist the local community to experience the minimal benefits of an organic vegetable bank for the welfare of the family, hoping to meet the needs of other communities in the future.

The aims are to describe the methodology used in the national level study of teacher education through the Teacher Professional Education Program or Pendidikan Profesi Guru (PPG)- Teacher Education and Development of Studies in Mathematics and share key findings related to mathematics preparation for future teachers. The research applied a quantitative approach with cross-sectional survey method with students of the master program of mathematics education class of 2019/2022 and 2020/2021. The results of the study show that future teacher performance: (1) has less opportunity to learn than high achievers in geometry, functions, calculus, and groups with mastery of linear algebra, number theory, analytic geometry, introduction to probability, and statistics and (2) has less opportunity for those who study school mathematics in data representation, calculus compared to linear algebra, analytic geometry, introduction to calculus, calculus, probability, and statistics. Thus, it can be concluded that attention and emphasis are needed on the type and depth of learning materials given to future teachers who continue their studies at the master's level. This pattern represents an extension to better future secondary school teachers.
