Penyakit busuk pangkal batang pada tanaman kelapa sawit di perkebunan yang disebabkan jamur ganoderma telah menyebabkan kerugian produksi tanaman. Kehadiran jamur ini diduga berasosiasi dengan vegetasi gulma yang berada dikebun, yang disebar melalui dengan spora dan miselianya. Oleh karena itu untuk mendeteksi awal keberadaan jamur ganoderma diperlukan pendekataan vegetasi gulma dengan analisis hara Cu dan Zn. Penelitian ini bertujuan untuk mengetahui hubungan keberadaan jamur ganoderma terhadap kadar hara Cu dan Zn pada vegetasi gulma yang dominan di perkebunan kelapa sawit. Penelitian ini dilaksanakan di blok 17, 16, dan 6 Afdeling VII Kebun Rambutan Kabupaten Serdang Bedagai dan analisis daun di Laboratorium Analitik PT. Socfin Indonesia, Medan. Penelitian ini dilaksanakan pada bulan Juli sampai dengan Agustus 2018. Metode penelitian ini menggunakan deskriptif analitik. Penelitian ini mengambil 3 jenis vegetasi gulma yang dominan (Cyperus rotundus, Cyclosorus aridus, dan Stenochlena palustris) kemudian dianalisis Cu dan Zn pada daun gulma. Hasil penelitian menunjukkan diperoleh 3 jenis gulma dominan disekitar kebun kelapa sawit yaitu Cyperus rotundus, Cyclosorus aridus, dan Stenochlena palustris. Hasil analisis kadar Zn dan Cu pada daun dari ketiga jenis gulma dominan disekitar kelapa sawit terinfeksi jamur ganoderma lebih rendah dibandingkan tanpa terinfeksi, kecuali pada gulma Stenochlena palustris kadar Cu lebih tinggi. Selisih persentase kadar Zn dan Cu pada daun gulma Cyperus rotundus, Cyclosorus aridus, dan Stenochlena palustris disekitar kelapa sawit terinfeksi dibandingkan tanpa terinfeksi jamur ganoderma masing-masing Zn adalah -42,72%; -43,92% dan -1,70% dan Cu masing-masing -27,13%; -25,80% dan +34,34%. Defisiensi kadar hara Cu dan Zn pada daun gulma diareal piringan maupun gawangan mati pada perkebunan kelapa sawit berpengaruh pada perkembangan spora ganoderma.

Mung bean (Vigna radiata L.) is one of the legume commodity crops which is allocated more in the household and industrial consumption sector as a raw material for food and beverages. However, its current production is still unable to meet national demand. Therefore, this study aims to increase mung bean production by using chicken manure and plant growth regulator (PGR) as well as an alternative in nourishing soil nutrients because they do not contain chemical compounds. The research method used a randomized block design factorial with two treatments. The first treatment of chicken manure application, consisting of A0 (0 g/plot) as control; A1 (2000 g/plot); A2 (4000g/plot); and A3 (4000 g/plot). The second treatment of PGR applications, consists of Z0 (0 cc/plant) as control; Z1 (0.5 cc/plant); Z2 (1.0 cc/plant); and Z3 (1.5 cc/plant). The material mung bean seeds of the Vima 1 variety. The parameters observed were the number of pods per sample and the number of pods per plot. To determine the effect of the treatment of the parameters observed a statistical test was carried out with the analysis of variances (ANOVA), if it had a significant effect then it was continued with the Duncan Multiple Range Test (DMRT) at 5% level. The results showed that the application of chicken manure and PGR had a very significant effect on the observed parameters. The best treatment is the use of chicken manure A2 (4000 g/plot) and PGR Z3 (1.5 cc/plant) as an alternative to increasing mung bean production.

Demand for onions is always increasing but is constrained by large areas, expensive fertilizer, sensitivity to climate change, expensive seed prices, pests, and disease attacks. The size of local shallot bulbs is much smaller than imported shallots, but the color of the bulbs is redder and the taste is spicier. In order to overcome this problem, there needs to be an effort to improve the plant and shallot cultivation activities using colchicine to obtain superior properties and in combination with cow manure. . This research aims to determine the effect of colchicine and cow manure on the growth and production of the Bima variety of shallots. The research was carried out in January–September 2023 in the experimental garden of the Faculty of Agriculture, Universitas Pembinaan Masyarakat Indonesia, Medan. The research method used a completely randomized design, namely colchicine concentration (0 ppm, 300 ppm, and 600 ppm), soaking time (0; 4 hours; 8 hours), and cow manure (0; 2kg; 4 kg), which was repeated in 3 repetitions. The results showed that the concentration of colchicine, soaking time, and cow manure had a significant effect on plant height, number of leaves, number of tillers, tuber diameter, wet tuber weight per hill, and wet tuber weight per plot. The 300 ppm soaking concentration treatment had a significant effect on these factors. for 8 hours and 4 kg of cow manure, and all treatments were significantly different from control plants.

Basal stem rot and upper stem rot of oil palms caused by Ganoderma boninense are important oil palm diseases faced by oil palm plantations in Indonesia. For many years, basal stem rot was found to infect older oil palms that were more than 25 to 30 years old, but the disease began to appear in oil palms that were 10 to 15 years old and was even found infecting oil palm nurseries. Community service will be carried out in October 2023 in Gunung Ambat village, Sei Bingai District, Langkat Regency. The aim of this service is for the public to receive information about prevention and actions that will be taken by smallholder oil palm plantation farmers in the Sei Bingai sub-district, Langkat Regency. The expected target is for the community to distinguish attacks caused by G. boninense so that prevention can be carried out early and there is no decline in people's palm oil production. The community service method is carried out through lectures, discussions, and direct visits to people's oil palm plantations. The implementation of service activities was carried out in preparation by coordinating with community leaders and extension workers, as well as the implementation unit of the Sei Bingai sub-district agricultural service, Langkat Regency. Carrying out lectures and discussions with a team of lecturers and students targeting smallholder oil palm plantation farmers.

Pengabdian masyarakat ini bertujuan untuk mendorong ekowisata mangrove berkelanjutan melalui pemberdayaan masyarakat dan kolaborasi internasional. Kegiatan ini dilaksanakan sebagai bagian dari program pengabdian internasional antara Universitas Tjut Nyak Dhien, Indonesia, dan Universitas Tottori, Jepang. Metode yang digunakan adalah pendekatan partisipatif melalui edukasi langsung, observasi lapangan, dan diskusi bersama kelompok masyarakat lokal “Peduli Pesisir.” Data dikumpulkan melalui wawancara, dokumentasi, dan keterlibatan dalam aktivitas masyarakat. Hasil menunjukkan bahwa masyarakat berhasil mengembangkan ekowisata berbasis mangrove dengan produk unggulan seperti kelapa pandan, madu Trigona, serta olahan ikan dan kepiting tradisional. Salah satu praktik berkelanjutan yang menonjol adalah budidaya lebah tanpa sengat (Meliponini) dengan sekitar 100 sarang aktif yang menghasilkan 12 liter madu per bulan. Wisatawan dapat mencicipi madu langsung menggunakan pipet, dan umpan balik menunjukkan apresiasi tinggi terhadap rasa autentiknya. Selain itu, kesadaran masyarakat dan pengunjung terhadap konservasi lingkungan semakin meningkat. Program ini juga menekankan pentingnya strategi manajemen yang lebih baik, termasuk informasi harga yang jelas, promosi daring, peningkatan fasilitas, serta edukasi konservasi. Kesimpulannya, kolaborasi ini terbukti efektif dalam meningkatkan kesadaran lokal, memperkuat praktik ekowisata, dan mendukung keberlanjutan jangka panjang ekosistem mangrove melalui pendidikan, keterlibatan masyarakat, dan promosi strategis. Pendekatan ini dapat direplikasi di wilayah lain yang ingin mengembangkan ekowisata selaras dengan keberlanjutan lingkungan.
