Abstract

The neglect of returning organic matter to the soil and the intensive use of chemical fertilizers inpaddy fields have caused the physical, chemical, and biological quality of the soil to decline. Such soilconditions cause the population of soil biota that plays a role in nitrogen fixation and phosphatesolubility to decrease. This study aims to determine the relationship between total microbes andnutrient levels of N, P, K in rice plants in Ajamu Village, Panai Hulu District, Labuhan Batu Regency.This research was conducted from December 2021 to January 2022. Sampling was carried out bytaking leaves and rhizosphere soil of rice plants at 5 zigzag sampling points in a rice field area.Parameters observed in this study were nutrient levels of N, P, K and total microbes. The analysis wascarried out using correlation and regression methods.

Abstract

This research was carried out in Afd II Village, West Bilah District, Labuhan Batu Regency, starting in October 2021. The aim of the study was to determine the effect on the growth of Red Chili (Capsium Annum L) plants on cutting shoots on chili leaves. Chili is a staple for consumption in everyday life. Chili peppers can be made more productive by using the right gardening techniques. Maintenance measures such as cutting shoots of chili plants with a dichotomous are one approach to increase chili yields. Pruning dichotomous shoots seeks to remove less productive plant parts to maximize. This study used a completely randomized design (CRD) with 4 treatments with 5 replications, in order to obtain 22 experimental units, each bed planted with 30 chili plants. The total number of plants is 30 x 5 = 150 plants. For the experimental unit, 3 were selected to be used as plant samples. From the observations, if the F test shows a significant effect, it will be continued with the Duncan' New Multiple Range test (DNMRT) at a 5% significance level. As treatment, namely: A = Pruning 7 DAP, B = Pruning 4th branch, C = No pruning, D = Pruning 14 DAP. Cutting the tops of leaves to increase the yield of the red chili, the results of the study concluded: 1. Red chili plants that were trimmed branches made the chili plants taller, 2. Trimming leaves caused the emergence of new leaf blades to increase 3. And cutting leaf shoots was useful for improve the yield of chili plant quality. Based on the results of the study, it is recommended to trim the 4th branch because it can increase growth.

Abstract

The purpose of this study was to analyze and describe the temporal distribution of arthropods on purslane (Portulaca oleracea L.) on red chili farms, Afdeling II Village, West Bilah Subdistrict, Labuhanbatu Regency. This research method is descriptive exploratory research with a quantitative approach. This is to describe and analyze the temporal distribution of arthropods in purslane (Portulaca oleracea L.). Data was observed from the arrival of arthropods at a predetermined time, namely three 3 observation times, including: time I (07.00-08.00), time II (12.00-13.00), and time III (16.00-17.00) for 10 minutes. Each time the observation was repeated 4 times. The results of this study showed that the daily visits of arthropods at 12.00-13.00 were higher than the daily visits at 07.00-08.00 and 16.00-17.00. Each family of arthropods has a different level of daily visits at each time of arrival which is caused by internal factors (physiological, reproductive ability, life cycle, age) and external factors (physical factors, food, temperature and humidity). The daily visit frequency of this arthropod indicates that purslane (Portulaca oleracea L.) is a habitat for arthropods and can be used as a refugia plant.

Abstract

Peat soils are classified as marginal soils and are prone to disturbance, so efforts to increase land productivity must be followed by efforts to prevent ecosystem damage. This study aims to analyze differences in nutrient content in peat land and permanent production forest areas in Sei Paham Village, Sei Kepayang District, Asahan District . Taking 5 soil sample points was carried out using a proposive random sampling method . The soil sample is then placed in a sterile plastic bag and immediately taken to the laboratory for analysis. The parameters of the soil analysis carried out included pH , C-total, N, P, K, Ca, Na, Mg, CEC and C/N. The results showed that in permanent production forest, the nutrient content was higher than peatland in all parameters of soil chemical analysis.

Abstract

Industri game yang berkembang pesat tidak hanya terjadi di Indonesia saja, namun di berbagai negara sudah mulai menunjukkan antusias terhadap industri game. Salah satunya seperti game Mobile Legends: Bang Bang yang dimana memiliki jutaan pengguna aktif. Popularitas Mobile Legends menyebabkan banyaknya pengguna Mobile Legends ini memberikan ulasan dan review. Penelitian ini kami tujukan untuk menganalisis ulasan para pengguna Mobile Legend dengan memanfaatkan metode algoritma K-Means Clustering. Data ulasan pengguna dikumpulkan dari Google Play Store dan memanfaatkan website Kaggle, Kemudian kami akan melakukan tahap preprocessing teks. Setelah itu data akan diubah menjadi representasi numerik menggunakan metode TF-IDF (Term Frequency-Inverse Document Frequency) sebelum diproses dengan algorima K-Means. Hasil ulasan pengguna menunjukkan bahwa ulasan dapat dikelompokkan ke dalam bebeerapa cluster, seperti ulasan positif (terkait kualitas, grafis, fitur, dan pengalaman bermain), ulasan negative (seperti bug, lag, dan server yang tidak stabil), serta ulasan netral yang berisi saran dan masukan. Evaluasi kualitas cluster dilakukan menggunakan metode DBI (Davies-Bouldin Index) yaitu untuk menentukan jumlah cluster secara optimal agar mendapat gambaran yang jelas mengenai berbagai persepsi dari pengguna, sehingga dapat menjadi dasar bagi pengembang dalam meningkatkan kualitas, memperbaki bug, dan juga mengoptimalkan pengalaman bermain. Dengan demikian, penggunaan algorima K-Means terbukti efektif dalam mengelompokkan ulasan pengguna. Serta dapat dijadikan alat bantu dan masukkan bagi pengembang dalam pengembangan aplikasi dan menyesuaikan ulasan para pengguna.

Abstract

Tingginya ketergantungan pada pupuk kimia, rendahnya kualitas budidaya, lemahnya pengemasan, dan terbatasnya akses pemasaran merupakan masalah mendasar yang menghambat daya saing agribisnis hortikultura di Desa Bandar Kumbul. Program pengabdian masyarakat ini dirancang untuk mengatasi permasalahan tersebut melalui pendekatan terintegrasi. Metode pelaksanaannya meliputi sosialisasi, empat modul pelatihan (pembuatan pupuk organik, budidaya berstandar GAP, pengemasan, dan pemasaran digital), penerapan teknologi inovatif, serta pendampingan intensif selama delapan minggu. Hasil evaluasi menunjukkan peningkatan signifikan pengetahuan dan keterampilan peserta, dengan rata-rata nilai post-test yang jauh lebih tinggi dibanding pre-test pada semua modul. Pada tataran praktis, program ini berhasil mendorong adopsi pupuk organik, menurunkan kehilangan hasil panen, meningkatkan kualitas produk sesuai standar supermarket, serta membuka akses pasar digital yang berdampak pada peningkatan pendapatan petani rata-rata sebesar 35%. Secara keseluruhan, program ini terbukti efektif sebagai model pemberdayaan yang mentransformasi ekosistem agribisnis dari hulu ke hilir, menciptakan keberlanjutan dan memperkuat ketahanan ekonomi lokal.
