Entog Dwarf coconut is a national superior variety. The purpose of this study was to determine the vegetative growth of Entog Dwarf coconut at 7-10 months of age. The research was conducted at the Palm Plant Research Institute in Manado (Upper Kima Experimental Garden and Ecophysiology Laboratory) using a factorial group randomized design with 2 factors and 3 replications. The first factor was the planting hole with a depth of 100cm and 60cm. The second factor was compound inorganic fertilizer with doses of 1.5kg, 1.0kg, 0.5kg, and control. Nutrient analysis of soil and leaves without fertilization at 7 and 10 months and after fertilization at 10 months. The results of the analysis of variance at the 5% level showed that planting holes had a significant effect, while compound inorganic fertilizers had a significant effect on vegetative characters. The tallest plants were about 51.2-63.7cm with a dose of 0.5-1.5kg while the shortest was 27.2cm, the largest stem circumference was 10.8-11.3cm with a dose of 0,5kg and 1.5kg while the smallest was 6.42cm, and the largest number of leaves was 3.67 midribs with a dose of 1.5kg while the smallest number was 2.67 midribs, where all vegetative characters were categorized as low in control plants. The interaction between the two factors had no significant effect on vegetative growth. The vegetative characters observed were positively correlated. The results of nutrient analysis of pH, moisture content, organic carbon, nitrogen, phosphorus, potassium, stomatal index, and chlorophyll showed little difference both without fertilization and after fertilization.

This study investigates the diversity of weeds in rice plants across Minahasa, South Minahasa, North Minahasa, and Tomohon regency, focusing on the environmental factors influencing the distribution and density of weeds. The research highlights that the diversity of weeds is significantly influenced by environmental factors such as rainfall, soil type, and water management practices applied by farmers. Species such as Marsilea crenata and Panicum disticum dominate areas with poor drainage, while Ludwigia hexandra and Fimbristylis litoralis thrive in fields with better drainage. Observations of weed density at 21 and 42 days after planting revealed that the competition between paddy and weeds changes as the paddy plants mature, with the initial dominance of weeds decreasing as the paddy plants grow stronger. The findings provide valuable insights into weed dynamics and the significant role environmental conditions play in determining their distribution. These results offer guidance for developing more effective and environmentally sustainable weed management strategies. Recommendations include selective herbicide use, mechanical soil cultivation, crop rotation, and improved water management. The study also suggests that further research is needed to assess the impact of climate change on weed diversity and the long-term effectiveness of weed management practices.

Pakoba fruit is one of the endemic flora of North Sulawesi which is rich in nutrients and has the potential to be fermented. The fermentation process occurs due to the bacteria in the fruit, including lactic acid bacteria (LAB). One of the interesting products from LAB fermentation is that it can produce secondary metabolites which have the potential to produce exopolysaccharides, namely high molecular weight and biodegradable polymers. This research aims to determine whether LAB can be obtained from fermentation of Pakoba marination and what types of LAB produce exopolysaccharides based on their phenotypic characteristics. This research uses a qualitative descriptive method to characterize the type of LAB and observe the exopolysaccharides produced by the bacteria. This research succeeded in isolating and identifying 10 LAB isolates based on their morphological and biochemical characters. Four isolates named MP(1)5.2, MP(1)7.1, MP(3)6.3, MP(3)7.2 can produce exopolysaccharides with a soft character but not mucus, where bacterial exopolysaccharides are believed to increase probiotics in the digestive tract. Genus level recognition (generic assignment) based on profile matching revealed that these four bacteria were from the genus Lactobacillus.

The Community Service activity partners are the Farmer Community, who are members of the Berkat Kayuuwi Kawangkoan Minahasa farmer group, with the following problems faced by the partners: 1) Low knowledge of farmer group members about organic fertiliser. 2) Low skills of farmers in empowering agricultural waste and household waste into organic fertiliser. 3). Low knowledge and skills of farmers in innovating daily community life activities in Kayuuwi Village, Kawangkoan District, such as household activities, farming, livestock raising which are found to have much waste that can be used as raw materials for making organic fertiliser so that it can increase community income while improving the quality of the soil and the surrounding environment. The methods used to achieve the PKM objectives were carried out in stages and systematically, starting with outreach and training. Then, direct field assistance until all activities were completed and partner issues were resolved. In addition to theoretical training, participants were also involved in hands-on practice in making solid compost. They were taught how to use a simple shredder as part of the application of appropriate technology. Evaluation was conducted by comparing pre-test and post-test results to assess participants' knowledge gains. The evaluation results showed a significant increase in farmers' understanding and skills, even reaching a 300% increase in some topics. Furthermore, organic fertiliser produced from agricultural and household waste was also directly utilised in peanut cultivation activities by farmer groups. This activity was not only educational but also productive because it encouraged farmers to be independent in meeting their fertiliser needs and opened up small business opportunities in organic farming. ABSTRAK Mitra kegiatan Pengabdian Kepada Masyarakat (PKM) adalah Masyarakat Tani yang tergabung dalam kelompok tani Berkat Kayuuwi Kawangkoan Minahasa dengan permasalahan yang dihadapi mitra sebagai berikut: 1). Rendahnya pengetahuan anggota kelompok tani tentang pupuk organik. 2). Rendahnya keterampilan petani dalam memberdayakan limbah pertanian dan limbah rumah tangga menjadi pupuk organik. 3). Rendahnya pengetahuan dan keterampilan petani dalam menginovasi aktifitas kehidupan masyarakat sehari-hari di Desa kayuuwi Kecamatan Kawangkoan, seperti aktivitas Rumah tangga, bercocok tanam, beternak yang didapati banyak limbahnya yang bisa dimanfaatkan menjadi bahan baku pembuatan pupuk organik sehingga bisa menambah pendapatan masyarakat sekaligus memperbaiki kualitas tanah dan lingkungan sekitar. Metode yang digunakan untuk mencapai tujuan PKM dilakukan secara bertahap dan sistematis dimulai dari sosialisasi, pelatihan, hingga pendampingan langsung di lapangan sampai seluruh kegiatan selesai dan permasalahan mitra teratasi. Selain pelatihan teori, peserta juga dilibatkan dalam praktek langsung pembuatan pupuk kompos padat. Mereka diajarkan menggunakan mesin pencacah sederhana sebagai bagian dari penerapan teknologi tepat guna. Evaluasi dilakukan dengan membandingkan hasil pre-test dan post-test untuk menilai peningkatan pengetahuan peserta. Hasil evaluasi menunjukkan adanya peningkatan signifikan dalam pemahaman dan keterampilan petani, bahkan pada beberapa topik mencapai kenaikan hingga 300%. Tidak hanya itu, pupuk organik yang dihasilkan dari limbah pertanian dan rumah tangga juga langsung dimanfaatkan dalam kegiatan budidaya kacang tanah oleh kelompok tani. Kegiatan ini tidak hanya bersifat edukatif tetapi juga produktif karena mampu mendorong petani untuk mandiri dalam memenuhi kebutuhan pupuk serta membuka peluang usaha kecil di bidang pertanian organik.

Tridax procumbens L. and Aloe vera L. are plants commonly used in the treatment of burns. This study was conducted to determine the effect of giving a combination gel of T. procumbens and A. vera leaf extract on second-degree burn healing in mice. This study used 24 male mice (Mus musculus) which were divided into four treatment groups, namely positive control (KP, Bioplacenton®); negative control (KN, gel base); leaf extract of T. procumbens 0.5% and A. vera 0.5% (P1); and leaf extract of T. procumbens 1% and A. vera 0.5% (P2). The process of inducing burns on the backs of mice requires the use of a 1x1 cm iron, which is subjected to heat in a fire for three minutes. The iron is placed on the mice's back for five seconds, which leads to the development of a second-degree burn. The gel was applied twice a day for 21 days. The highest level of burn wound healing was recorded with the Bioplacenton® treatment, which achieved a full recovery of 100% on day 15. Following this, the combined gel treatment of 1% T. procumbens leaf extract and 0.5% A. vera also reached 100% healing by day 18. While it may not be as potent as Bioplacenton®, the gel formulation containing 1% T. procumbens and 0.5% A. vera leaf extract presents a viable alternative for treating second-degree burns.
