As long as the issues with peat soil, particularly with some of its chemical qualities, can be treated properly, it has the potential to be utilized as agricultural land. Empty oil palm fruit bunches (EFB), which are produced by the size of oil palm farms, can be used to make biochar and EFB compost, which are then combined to create biokom, which can enhance soil structure and increase the availability of phosphorus in peat. Aspergillus oryzae-Tb7 is one of the phosphore solubilizing fungus (FPP) that aid in accelerating the release of accessible P. The byproduct of burning coal in a PLTU that is alkaline by nature and capable of raising soil pH to promote an increase in available P is known as coal fly ash (CFA). The goal of this study's conclusion was to ascertain the impact on the chemical characteristics of maize plants' uptake of P as well as soil pH, CEC, soluble Fe, and available P.A single-component, completely randomized design was used in this study (CRD). The factors A 0, which stood for "control without treatment," A1, "P fertilizer," A2, "P + Biochar fertilizer," A3, "P + CFA fertilizer," A4, "P fertilizer + Biokom + FPP," and "P fertilizer + Biokom + CFA + FPP," were tested. There were three repetitions of each therapy, yielding 18 trials. The findings show that the use of biokom, FPP, and CFA can improve P uptake, soil pH, CEC, and soil-accessible P while lowering plant dry weight and soluble Fe.

Community Service Program (KKN) are one of the mandatory programs that must be carried out by students. This TOGA knowledge increasing activity is a form of the Community Service Program (KKN) work program which aims to increase the knowledge and skills of SMAN 2 Dumai students in cultivating family medicinal plants (TOGA). TOGA can be used to treat various diseases such as fever, fever, cough, stomach ache and itching. Usually the medicinal plants chosen are plants for first aid for minor illnesses such as fever and cough. Through training activities and TOGA planting practices on empty school land, students, especially PMR members, are actively involved in the cultivation process. The results of the activity showed an increase in students' awareness of the benefits of TOGA and their ability to identify and care for various types of medicinal plants. Apart from that, the presence of TOGA in the school environment also contributes to creating a healthier and more beautiful learning environment.

Pembelajaran matematika tidak hanya menuntut penguasaan konsep, tetapi juga pemaknaan proses berpikir dalam konteks kehidupan nyata, termasuk budaya lokal. Penelitian ini bertujuan mengidentifikasi dan menganalisis konsep penjumlahan dan aritmetika modulo dalam praktik adat babilangan serta menjelaskan langkah-langkah pelaksanaannya di masyarakat Tapin. Penelitian menggunakan pendekatan kualitatif eksploratif. Data dikumpulkan melalui wawancara semi-terstruktur dan dokumentasi terhadap tiga informan dari desa berbeda yang memahami Adat Babilangan. Analisis data menggunakan model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan.Hasil penelitian menunjukkan bahwa Adat Babilangan berakar pada praktik hisab berbasis aksara hijaiyah yang diwariskan secara turun-temurun. Konsep matematis yang ditemukan meliputi penjumlahan bilangan bulat serta aritmetika modulo multibasis, seperti modulo 12 untuk menentukan sifat individu serta modulo 3, 5, dan 7 dalam penentuan nasib pernikahan melalui perhitungan nilai aksara. Meskipun terdapat variasi nilai aksara dan perbedaan penafsiran antar narasumber, struktur perhitungan tetap konsisten, yaitu penjumlahan yang diikuti pembagian bersisa. Temuan ini menunjukkan bahwa Adat Babilangan merupakan bentuk matematika informal yang berpotensi menjadi konteks pembelajaran yang mengaitkan konsep matematika formal dengan budaya lokal. Kata kunci: Adat Babilangan, Etnomatematika, Modulo, Penjumlahan Abstract: Mathematics learning requires not only conceptual mastery but also meaningful understanding of thinking processes in real-life contexts, including local cultural practices. This study aims to identify and analyze the concepts of addition and modular arithmetic embedded in the Adat Babilangan tradition and to systematically describe the procedures used in its implementation within the Tapin community. The study employed an exploratory qualitative approach. Data were collected through semi-structured interviews and documentation involving three participants from different villages who are knowledgeable about Adat Babilangan. Data analysis followed the Miles and Huberman model, including data reduction, data display, and conclusion drawing. The findings indicate that Adat Babilangan is rooted in a traditional calculation system based on the Arabic (Hijaiyah) script, transmitted across generations. The identified mathematical concepts include integer addition and multi-base modular arithmetic, such as modulo 12 for determining individual characteristics, and modulo 3, 5, and 7 for determining marital compatibility through calculations based on the numerical values of Hijaiyah letters. Despite variations in letter values and differences in interpretation among informants, the underlying computational structure remains consistent, involving addition followed by division with remainders. These findings suggest that Adat Babilangan represents a form of informal mathematics with potential as a culturally relevant context for connecting formal mathematical concepts to local traditions.
