Abstract

Rice is a staple food for humans living in East Asia. Rice is a crystal fruit. The Latin name for rice is Oryza Sativa. Rice plants are 110-120 days old. The selection of quality rice seeds by farmers is seen from the bright yellow color of the rice without black/brown spots, its large size and rounder. Rice seeds that are not of good quality are dark brown in color, have black/brown spots, and are flat in shape. The absence of superior rice recognition technology that is not Android-based in real time is the main reason for this research. The focus of this research is to identify superior and non-superior rice in Inpari HDB 32 rice with a high recognition accuracy rate of more than 70 percent with a viewing angle of 0-180 degrees using the real-time ANN method. The training data used in this research was 1000 datasets consisting of 350 superior rice datasets and 650 non-superior datasets. The smart model for classifying rice seeds that has been built in this research is generally able to run well where the classification accuracy obtained is quite good. The classification accuracy of the ANN model during training of the neural network model was able to classify rice seeds with an accuracy of 70-100% with the confidence value of the real-time classification results ranging from 65-98%. Real-time classification of rice grains with maximum accuracy of 96% and many grains 73%.

Abstract

Sungai Besitang merupakan salah satu sungai yang terletak di Kabupaten Langkat, Provinsi Sumatera Utara. Kawasan sekitar hulu dan hilir sungai memiliki pemukiman dan industri. Sungai Besitang juga menjadi habitat berbagai spesies ikan belana k (Mugil cephalus), salah satu spesies yang ditangkap oleh nelayan sebagai sumber mata pencaharian, baik untuk konsumsi pribadi maupun untuk dipasarkan di pasar tradisional. Penelitian ini bertujuan untuk menganalisis populasi ikan belanak di Sungai Besitang, Kabupaten Langkat. Penelitian ini merupakan jenis penelitian deskriptif kuantitatif dengan pengambilan sampel menggunakan metode observasi dan eksperimen. Pengambilan sampel dilakukan menggunakan alat tangkap jaring. Sampel diambil dari tiga lokasi, yaitu: lokasi pertama di kawasan hulu, lokasi kedua di kawasan perindustrian, dan lokasi ketiga di kawasan pemukiman. Sampel yang diperoleh kemudian dianalisis untuk mengetahui populasi ikan belanak. Hasil penelitian menunjukkan bahwa populasi ikan belanak di Sungai Besitang, Kabupaten Langkat, dengan nilai 1,13, menunjukkan kriteria rendah.

Abstract

Spotted deer (Axis axis) is one of the protected deer species in Indonesia. Spotted deer have been listed on the IUCN Red List of Threatened Species, with a conservation status of LC (Least Concern). In the conservation of spotted deer, failure often occurs due to diseases that arise due to conditions that are not in accordance with their natural habitat. One of the main problems is parasitic infections. This study aims to determine the type, prevalence and intensity of Platyhelminthes in spotted deer (Axis axis) in Langsa City Forest Park, Aceh. The samples used were the feces of 13 spotted deer in Langsa City Forest Park, Aceh. The type of research is descriptive quantitative with observation methods. Data analysis used is a description of prevalence and intensity values. The results showed that there were 3 types of Platyhelminthes, namely Schistosoma intercalatum and Schistosoma mansoni from the Schistosomatidae family, Strigeatida order, Trematoda class and Taenia sp. from the Taeniidae family, Cyclopphyllidea order, Cestoda class. Schistosoma intercalatum has a prevalence of 23.07% (frequent) and intensity of 1.3 (light parasite), Schistosoma mansoni has a prevalence of 15.38% (frequent) and intensity of 1 (light parasite) and Taenia sp. has a prevalence of 38.46% (general) and intensity of 1.4 (light parasite).

Abstract

Pertumbuhan tanaman lokio atau yang sering disebut bawang batak dipengaruhi oleh pemupukan yang sesuai untuk mendukung produktivitas dan keberlanjutan pertanian. Pupuk organik cair dari tanaman babandotan berpotensi sebagai alternatif pupuk kimiawi yang ramah lingkungan dan meningkatkan kesuburan tanah. Penelitian ini bertujuan untuk mengkaji pengaruh penambahan pupuk organik cair babandotan terhadap pertumbuhan lokio, khususnya tinggi tanaman, jumlah daun, dan diameter batang. Metode yang digunakan adalah eksperimen dengan rancangan acak lengkap (RAL) terdiri dari empat perlakuan, yakni tanpa pupuk (kontrol), dan dosis POC 100 ml, 150 ml, serta 200 ml, yang diaplikasikan pada tanaman lokio. Data pengamatan dilakukan selama periode pertumbuhan, kemudian dianalisis dengan analisis varians (ANOVA) satu jalur dan uji lanjutan Duncan Multiple Range Test (DMRT) pada tingkat signifikansi 5%. Hasil menunjukkan bahwa pemberian pupuk cair babandotan secara signifikan meningkatkan semua parameter pertumbuhan, dengan dosis 200 ml (perlakuan P3) memberikan hasil terbaik secara statistik. Temuan ini mengindikasikan bahwa pupuk organik cair dari babandotan efektif dalam mendukung pertumbuhan lokio secara alami dan berkelanjutan.

Abstract

Water is the second most important element for life after air. Water is a clear liquid, odorless, colorless, and tasteless. Water is a basic need for living creatures, especially drinking water. One way of processing drinking water is by freezing it into ice. Ice cubes are a food that is widely known and is usually considered safe for consumption. Coliform bacteria serve as a general marker of contamination in food and water. Coliform bacteria found in the human body can cause several diseases, including diarrhea. The aim of this research was to confirm the presence of coliform bacteria, measure the level of contamination, and identify the specific type of coliform bacteria that contaminated crystal ice from three ice producers located in Langsa City. This research is descriptive in character. Ice crystal samples were tested using the Most Probable Number (MPN) approach. Furthermore, bacteria were identified through microscopic analysis using the gram staining method and biochemical testing, especially IMViC. Each ice crystal sample showed coliform contamination, exceeding the precautionary limits set out in Minister of Health Regulation number 492 of 2010. The highest amount of contamination was 6 MPN/100mL and the lowest amount of contamination was 4 MPN/100 mL. There were 2 types of coliform bacteria found in this study, namely: Escherichia coli and Enterobacter aeroganes.

Abstract

Soybeans (Glycine max L. Merrill) After rice and corn, it is the third most important food commodity and occupies a strategic position in the country's food policy, It plays a very important role in the nutrition of the Indonesian population. The aim of this study was to investigate the effects of soybean plant (Glycine Max). The aim of this study is to investigate the effects of green manure Pennisetum purpureum on plant growth (Merrill). The study was conducted in Batu Melengangan Village, Langkat Regency, using an experimental method involving 2 treatments, namely P0 (without green fertilizers) and P1 (200 grams of green elephant grass fertilizer), and a completely randomized, non-evidence-based design (CRD). In analyzing the data from this study, the SPSS program used parametric tests, i.e. Anova and Duncan tests, and nonparametric tests, i.e. KRUSKAL-Wallis and Mann-Whitney tests. The results of the study show that there was effectiveness of elephant grass green fertilizer (Pennisetum purpureum) on the growth of soybean stem height with an average of 36.25 cm, number of soybean leaves with an average of 46,775 pieces, the age at which soybean flowers emerged with an average of 36.6 days, and the age at which soybeans emerge is an average of 43.2 days. The most effective green manure treatment for the growth of soybean plants (Glycine max L. Merrill) was in treatment P1 (200 gr grass green manure).
