Ultisols, including those of Langsa, Aceh, are known to have low fertility due to low pH, low available nutrients, low base saturation, high pH and exchangeable Al, and low cation exchange capacity. These problems can be alleviated by applying organic amendments to the soil. One of the soil amendments is biochar. This study aimed to elucidate the potential of oil palm and cacao waste biochar for improving the chemical properties of an Ultisol of Langsa, Aceh. Biochars generated from oil palm kernel shell (PKS), oil palm empty fruit bunch (PEFB), and cacao pod husk (CPH) were applied to the soil and incubated in the laboratory for 16 weeks. At 4, 8, 12, and 16 weeks after incubation, the changes in soil chemical properties were measured. The results showed that applying different types of biochar significantly improved the chemical properties of the Ultisol of Langsa. Specifically, PEFB biochar caused significant increases in soil pH (H2O and KCl), total phosphorus, available phosphorus, organic C, and cation exchange capacity. These increases became more pronounced with longer incubation times. In addition, using PEFB biochar resulted in the lowest levels of exchangeable Al and Fe in the soil. These levels decreased further with longer incubation times. In general, PEFB biochar produced at a pyrolysis temperature of 450oC for 4 hours is the most effective biochar for improving the chemical properties of the Ultisol of Langsa.

In providing areca seeds, there is an obstacle that often arises, namely the nature of dormancy so that it takes only a little time to germinate. This condition can be overcome by administering natural ZPT such as young coconut water, shallots, bamboo shoots and banana stems. The aim of the research was to determine the ability of a mixture of natural PGR types and soaking time to stimulate the germination of areca nut seeds. The research was conducted from June to August 2023, the experimental design was RAK factorial pattern consisting of 2 factors: The first factor was a mixture of natural PGR, Coconut Water (AK), Shallot Extract (BM), Banana Weevil Extract (BP), and Bamboo Shoot Extract ( RB) with a composition of 5 levels, namely: Z0: Air (control); Z1 : AK + BP; Z2 : BM + AK + RB; Z3 : RB + BP + BM; Z4 : AK + BM + BP + RB. The second factor of soaking time consists of 3 levels, namely: L1: 18 hours; L2: 24 hours; L3 : 30 hours. The research results showed that the treatment of a mixture of natural PGR types had a very significant effect on the vigor index and root length. The long soaking treatment had a very significant effect on the length of the tuna, but had a significant effect on the germination time and speed of seed growth. There was no interaction between the two treatments. The best natural PGR mixture is recommended to use Z2, Z3 and Z4 treatment with L2 soaking time

The oil palm land donated to Universitas Samudra is planned for the development of the campus area, including the construction of a number of buildings and supporting facilities. However, the process of identifying and mapping oil palm plants has been done manually, which is time-consuming, inefficient, and prone to errors. This problem underscores the need for faster and more accurate methods to support spatial data-based planning. This study aimed to calculate the number of oil palm plants in 2022 and 2023 at the University of Samudra using the template matching method with eCognition Developer software, as well as evaluate the accuracy of automatic detection results based on aerial images obtained using drones. The research was carried out using survey methods and descriptive analysis, involving primary data in the form of aerial imagery and field validation, as well as secondary data from the map of the oil palm plantation area of Samudra University. The results of the study show that the number of oil palm plants in 2022 based on automatic calculations was 2,060 trees, while the results of manual validation showed the actual number of 2,169 trees with a difference of 109 trees. In 2023, the automatic calculation detected 1,932 trees, while the actual number was 2,030 trees, with a difference of 98 trees. The accuracy level of automatic calculations in 2022 had an average accuracy of 98.56%, recall of 94.05%, and F1-score of 95.63%, higher than in 2023 with precision of 97.41%, recall of 92.73%, and F1-score of 94.98%. Then the template matching method is effectively used for oil palm tree detection and can support the planning of campus area development efficiently. The use of this technology is expected to be a model that can be implemented in various other educational institutions.

Gula semut dibuat dari nira pohon aren dan merupakan gula merah versi bubuk yang akrab disebut gula merah kristal. Disebut gula semut karena bentuknya mirip rumah semut yang bersarang di tanah. Pohon ini termasuk dalam jenis tumbuhan palmae (Palm Sugar atau Palm Zuiker). Gula semut menjadi makin popular di dunia, terutama negara-negara maju seperti Eropa dan Jepang. Pengolahan usaha rumah tangga gula aren sudah lama dilaksanakan di Kecamatan Rantau Kabupaten Aceh Tamiang. Motode pengabdian kepada masyarakat (PKM) ini dilakukan melalui beberapa tahapan meliputi: 1) Survey persiapan, 2) Pelaksanaan pelatihan (sosialisasi, demontrasi dan pemberian alat kepada mitra), 3) Monitoring dan evaluasi untuk mengetahui keberlanjutan program. Tujuan PKM yang akan dilaksanakan adalah melatih pengrajin gula aren memproduksi alternatif produk gula aren tidak hanya dalam bentuk gula merah tetapi juga menjadi gula semut (remah). Terdapat fenomena pengunjung kafe dan warung kopi terutama penikmat minuman kopi di Aceh, sudah mulai bergeser dari pemanis gula pasir tebu menjadi gula aren. Peluang pasar terbuka lebar disebabkan gula semut yang diproduksi dengan kualitas baik dalam kemasan sachet serta botolan. Kegiatan PKM ini dapat meningkatkan pengetahuan dan keterampilan pengrajin sehingga dapat memproduksi gula semut dengan kualitas baik, pengemasan yang modern hingga kepemasaran yang efisien serta memperoleh keuntungan yang layak

This study aims to determine the level of student interest in futsal extracurricular activities and the factors that influence it at State Junior High School 45 Medan. The method used is a qualitative descriptive method with a survey approach using an instrument in the form of a closed questionnaire consisting of 42 statements. The subjects in this study were 30 students who participated in futsal extracurricular activities. The results of the study showed that the majority of students had a high interest in futsal extracurricular activities. Overall, the results of the study were that 23% of students were in the very high interest category, 60% of students were in the high interest category, 7% of students were in the medium interest category, 7% of students were in the low interest category, and 3% of students were in the very low interest category. Factors that influence student interest are classified into two, namely intrinsic factors (attention, feelings of pleasure, and activity) and extrinsic factors (the role of teachers/coaches, facilities, family support, and the environment). Both factors significantly contribute to the level of student interest in participating in futsal activities at school. This study demonstrates that the success of futsal extracurricular activities is significantly influenced by the efforts of coaches, the availability of adequate facilities, and a supportive environment. These findings are expected to inform evaluation and improvement for schools in managing and developing extracurricular programs to make them more engaging and beneficial for students.
