Abstract

Indonesia has a variety of medicinal plants that are efficacious for preventing or treating various diseases. Each region has unique medicinal plants, such as in North Sulawesi, there are many medicinal plants with local names of "Jarak" (Jatropha curcas), "Jarak Merah" (Jatropha multifida), "Miana" (Coleus Scutellarioide), and "Sesewanua" (Clerodendron Squmatum Vahl). This research applies the Convolutional Neural Network (CNN) method to identify the types of medicinal plants of North Sulawesi based on leaf images. Data was collected directly by taking photos of medicinal plant leaves and then using the augmentation process to increase the data. The first stage is conducting training and validation processes using 10-fold cross-validation, resulting in 10 classification models. Evaluation results show that the lowest validation accuracy of 98.4% was obtained from fold-4, and the highest was 100% from fold-2. The third stage was to run the testing process using new data. The results showed that the worst model produced a test accuracy of 80.91% while the best model produced an accuracy of 87.73% which means that the identification model is quite good and stable in classifying types of medicinal plants based on its leaf images. The final stage is to develop a web-based system to deploy the best model so people can use it in real-time

Abstract

Climate change since 2019 has had a significant impact on paddy plant growth, presenting new challenges in optimizing food production. 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. Keywords: Spatial Mapping, Thermal Unit, Paddy (Oryza sativa L.) Abstrak Perubahan iklim yang terjadi sejak tahun 2019 telah memberikan dampak signifikan pada pertumbuhan tanaman padi, menghadirkan tantangan baru dalam mengoptimalkan produksi pangan. Pendekatan efektif dalam menentukan waktu panen adalah Konsep Thermal Unit, yang memperhitungkan akumulasi suhu harian selama pertumbuhan tanaman padi. Pemetaan spasial menggunakan Sistem Informasi Geografis digunakan untuk menganalisis kondisi lahan dan kebutuhan panas dalam pertanian padi. Hasil pemetaan ini berguna untuk perencanaan, pembudidayaan, serta pengambilan kebijakan pemerintah dan disosialisasikan kepada petani. Penelitian ini dilaksanakan pada bulan Agustus – November di Desa Rasi, Minahasa Tenggara Provinsi Sulawesi Utara. Pengumpulan data penelitian dilakukan dengan pengamatan fenologi tanaman padi, mengambil titik koordinat lokasi dan waktu/tanggal semai-panen tanaman padi, kemudian dilakukan digitasi Citra Landsat, Sas Planet ArcGIS 10.8 dan menganalisis suhu harian untuk mendapatkan nilai thermal unit.

Abstract

Seeds are an important input for increasing corn production and productivity. The use of low-quality seeds causes low corn production. 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. 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. 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. These data show that the Lamuru variety has the highest population of the S. zeamais pest. 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. 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. The Lamuru variety has a higher number of damaged or hollow corn seeds compared to other varieties. Differences in the nutrient content and seed hardness of each corn seed variety can cause high damage to the Lamuru variety. Keywords: Warehouse Pests, Sitophilus oryzae, Experimental methods, Pest populations, damage to corn seeds.
