The methods used in this research were field observations and interviews with healers and people who use weed as a traditional medicinal plant. The data/samples that will be taken over 4 sub-districts. The ethnic diversity that exists in Indonesia means that the use of weed as medicine is increasingly diverse. North Sulawesi Province has a wealth of plants as traditional medicines which can be processed to national standards into herbal medicines. The indigenous population in North Bolaang Mongondow Regency consists of the Kaidipang tribe and the Bintauna tribe. Various ethnic groups, including the Sangihe ethnic group and the Mongondow ethnic group, still use weed as an ingredient in traditional medicine. Weeds are wild plants defined as nuisance plants because they interfere with farmers' activities in cultivating crops and can reduce crop production. Apart from disturbing cultivated plants, weeds can be used as medicinal raw materials. Many types of weeds are used by the community as traditional medicine. Certain types of weed have been developed in the form of industrial-scale medicines. These weed species include Peperomia pellucida (L.), Cyperus rotundus L., Heliotropium indicum L., Eleusine indica (L.) Gaernt, Ageratum conyzoides L. The results of the research show that people in East Bolaang Mongondow Regency still use weed as a mixture of traditional medicinal ingredients.</p> <p><strong>Keywords: medicinal plants, potential of weeds as medicinal plants</strong></p> <p><strong>Abstrak</strong></p> <p>Tujuan penelitian ini adalah memperoleh data jenis gulma yang berpotensi sebagai tumbuhan obat dan dimanfaatkan masyarakat di Kab.

An effective approach in determining the harvest timing is the Thermal Unit Concept, which takes into account the accumulation of daily temperature during the rice plant's growth. Spatial mapping using Geographic Information System (GIS) is employed to analyze land conditions and heat requirements in paddy cultivation. The mapping results are valuable for planning, cultivation, governmental policy-making, and dissemination to farmers. This research was conducted from August to November in the Rasi Village, Southeast Minahasa, North Sulawesi Province. Data collection involved observing the phenology of rice plants, recording coordinates of planting and harvesting locations, and digitizing Landsat images using SAS Planet and ArcGIS 10.8. Daily temperature analysis was carried out to obtain thermal unit values. The digitized map revealed the paddy field area in Southeast Minahasa Regency to be 3,002.621 hectares, distributed across all sub-districts. The sub-district with the largest paddy field area was North Tombatu, covering 521.362 hectares, while South Touluaan had the smallest area at 32.142 hectares. The Thermal Unit analysis indicated that Southeast Minahasa Regency/Rasi requires 1,285.11 thermal units, with varying heat requirements in each growth phase. During the seeding-planting phase, paddy plants need 292.79 °C, seedling-transplanting 460.04 °C, seedling-anthesis, and heading 217.57 °C, and during the anthesis and heading-harvest phase, paddy plants require 314.71 °C.</p> <p><strong><em>Keywords: Spatial Mapping, Thermal Unit, Paddy (Oryza sativa L.)</em></strong></p> <p><strong>Abstrak</strong></p> <p>Perubahan iklim yang terjadi sejak tahun 2019 telah memberikan dampak signifikan pada pertumbuhan tanaman padi, menghadirkan tantangan baru dalam mengoptimalkan produksi pangan.

The purpose of this study is to investigate lowland rice growth and yield by using composted straw instead of NPK fertilizer. Implemented in Tara-Tara II village, West Tomohon sub-district for 5 (five) months with one factor treatment, namely the ratio of NPK fertilizer dose and straw compost dose: 100% NPK + straw compost 0% straw compost (P0), 75% NPK + 25% straw compost (P1), 50% NPK + 50% straw compost (P2), 25% NPK + 75% straw compost (P3), and 0% NPK + 100% straw compost (P4). The variables observed included: plant height, number of fodder, number of panicles/clumps, weight of 100 harvested dry grains, number of grains/panicles, percentage of smooth grains/clumps and harvested dry grain yield. Substitution of NPK fertilizer with compost straw has no effect on the height of lowland rice plants using the SRI (System of Rice Intensification) method, but does affect the number of productive tillers. The highest number of productive tillers was found in P2 (50% NPK + 50% straw compost), P3 (25% NPK + 75% straw compost) and P4 (0% NPK + 100% straw compost), with an average value of 31, respectively. 27; 28.20 and 27.53 tillers, while treatment P3 (25% NPK + 75% straw compost) and lower values in treatments P0 (100% NPK + 0% straw compost) and P1 (75% NPK + 25% straw compost ) with an average value of 25.83; and 25.67 offspring.</p> <p>&nbsp;</p> <p>Keywords: System of Rice Intensification (SRI), rice, straw compost.</p> 2024-01-30T00:00:00+08:00 Copyright (c) 2024 Rantung Rantung , Jeanne M.

This case study was conducted at the Regional Environmental and Forestry Law Enforcement Office in Manado, integrating interviews, surveys, and thematic analysis over a span from 2016 to 2023. Results showed that social media, particularly Facebook, was utilized in 71% of the wildlife trade cases, predominantly involving avian species. Traders employed sophisticated methods including the use of anonymous accounts and disguised packages to evade detection. Law enforcement operations have included forest security traps and wildlife circulation interventions, but challenges remain in prosecuting major financiers and dismantling international networks. It can be concluded that effective enforcement is hindered by technologically sophisticated traders and the need for more robust international cooperation and legal frameworks.</p> <p><strong>Keywords</strong>: wildlife trade, social media, law enforcement, North Sulawesi.</p> <p><strong>Abstrak</strong></p> <p>Perdagangan satwa liar ilegal merupakan masalah global yang signifikan, yang diperparah dengan penggunaan platform media sosial yang meningkat.

Watersheds (DAS) are part of the unity of resources where humans actively use them. In this study, the aspect studied was the condition of the soil texture which aims to determine the erodibility (K) of the soil around the Kombot watershed. This study used survey methods and laboratory analysis to obtain data on soil texture and erodibility (K).The results showed that: 1) The soil erodibility value was very high in the soil sample (1) with a K value of 0.60 at a slope of 0-40<sup>0</sup> with land use namely moor while soil texture class was dusty clay, 2) The soil erodibility value of low value is found in the soil sample (13) with a K value of 0.17 on slopes 9-14<sup>0</sup> with plantation land use while the soil texture class is sandy loam, 3) soil texture is a factor that affects the value of soil erodibility (K), because soil texture has sensitivity to erosion.</p> <p>Key words: Kombot watershed, soil erodibility, soil texture</p> <p><strong>Abstrak</strong></p> <p>Daerah Aliran Sungai (DAS) merupakan suatu wilayah dataran yang dibatasi oleh perbukitan atau pegunungan yang berfungsi sebagai tempat menampung, menampung, dan mengalirkan air dari hulu ke hilir sungai.

The use of low-quality seeds causes low corn production.&nbsp; The research aims to determine the development of the S. zeamais pest on corn seeds of varieties Bisi 18, JH 37, Lamuru, Pertiwi 3, and Batras 1. This research used a Completely Randomized (CRD) design with five treatments and three replications.&nbsp; As treatments were 5 varieties of corn seeds, namely Bisi 18, JH 37, Lamuru, Pertiwi 3, and Batras 1. The research method used was the Experimental Method, namely experimental research by researching the influence of the S. zeamais pest on five varieties of corn seeds.&nbsp;</p> <p>The results of variance analysis of differences in S. zeamais populations on corn seeds of the Bisi 18, Jh 37, Pertiwi 3, and Batras 1 varieties showed that the results were not significantly different except for the Lamuru variety which had significant differences.&nbsp;&nbsp; These data show that the Lamuru variety has the highest population of the S. zeamais pest.&nbsp; The high population of the pest S. zeamais on corn seeds of the Lamuru variety compared to other varieties could be caused by the pest being more attracted to the physical condition, nutritional, and chemical content of the seeds.&nbsp; The results of variance analysis of differences in damage between corn seed varieties due to S. zeamais attack showed real and very significant differences, except between the Betras 1 and Pertiwi 3 varieties which were not significantly different.&nbsp; The Lamuru variety has a higher number of damaged or hollow corn seeds compared to other varieties.&nbsp; Differences in the nutrient content and seed hardness of each corn seed variety can cause high damage to the Lamuru variety.&nbsp;</p> <p>&nbsp;</p> <p>Keywords: Warehouse Pests, Sitophilus oryzae, Experimental methods, Pest populations, damage to corn seeds.</p> <p><strong>Abstrak</strong></p> <p>Benih merupakan input penting bagi peningkatan produksi dan produktivitas tanaman jagung.
