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.

Organizational vision serves as a strategic compass that directs all elements of an institution toward long-term goals. However, without effective leadership, the process of internalizing and operationalizing this vision often fails to reach its full potential. This community service initiative aimed to strengthen the capacity of educational personnel in pesantren-based institutions in Suryalaya by developing their understanding and application of effective leadership principles. The intervention employed participatory approaches through interactive workshops, group discussions, and strategic planning simulations. Thirty education staff members from various institutions took part in the program, representing roles from school leadership to teaching and administration. The results showed a significant increase in the participants’ ability to articulate their organizational vision, identify key performance indicators, and develop actionable leadership strategies. Post-activity evaluation indicated that 90% of participants considered the program useful and applicable to their institutional context. This program highlights the importance of aligning leadership capacity with the organizational vision to foster institutional resilience and progress.

Langsa City is one of the areas that has a fairly large expanse of land for agricultural activities for wetland farming. In addition to the leading plantation commodities, the Aceh Province Agriculture and Plantation Service has scheduled to develop tobacco as one of the leading commodities in Langsa City. Tobacco commodity is a new superior commodity developed in Langsa City starting from 2021 in Pondok Kemuning Village, and 2023 in Buket Meutuah Village, East Langsa District. The productivity and quality of the tobacco are still not optimal, because information on the quality and characteristics of the land for the tobacco development plan in Langsa City is still not known for certain. This study uses a survey method with descriptive analysis based on field observations and laboratory analysis. The process of determining land suitability is carried out using spatial operations by utilizing GIS applications. Based on the physical and chemical analysis of the soil at the sample points and the results of the interpretation of remote sensing data, it was found that the actual land suitability results for tobacco plants in the rice fields of Langsa City in SLH 1 and SLH 2 are Class S3-wa, nr, na with each SLH 1 being 951 Ha (90.65%) and SLH 2 with an area of 98 Ha (9.35%). The results of potential land suitability after efforts to improve the limiting factors in SLH 1 and SLH 2 are class S2-wa orup one level from the actual land suitability class.Keywords: Evaluation, Land, Tobacco, Paddy Fields, GIS

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
