Abstract

Abstract The purpose of this activity is to provide information about how the Prospect of Palm Plant Development (Arenga pinnata Merr) for food and energy security as well as processed products from palm trees, so that it is useful for the community, encouraging community awareness and awareness to preserve the environment. This activity was carried out in Buluh Awar Village, Sibolangit District, Deli Serdang Regency, involving the community in Buluh Awar Village and the Teaching Staff of the Agrotechnology Study Program, Faculty of Science and Technology, Biology Education Study Program, Teaching and Education Faculty, Labuhan Batu University, Postgraduate Study Program in Agrotechnology, Faculty Agriculture of the University of North Sumatra and the Faculty of Forestry of the University of North Sumatra. Agrotechnology Study Program, Faculty of Agriculture, Muhammadiyah University, South Tapanuli, Agrotechnology Study Program, Faculty of Agriculture, Graha Nusantara University, Padang Sidempuan. The main problem is the planting of sugar palm, which is generally not yet cultivated so that crop productivity is low and it is feared the plant population will decline. Since sugar palm plants have economic, social, cultural and conservation functions, it is wise to cultivate sugar palm and rehabilitate plants that grow naturally and irregularly in order to increase plant productivity. The results of the activity show that the cultivation of palm sugar plant has good hopes or prospects in the future. Processed products from palm plants such as sugar, drinks, and vinegar can be used to improve food security, while bioethanol can be used as an alternative energy source.

Abstract

Vertical farming technique is a method used for community settlements that have narrow land optimally. This technique will arrange plants in tiers from top to bottom with various types of plants. The purpose of this community service (PKM) is to help improve the understanding and ability of the Karang Taruna Tani Villa Pasir Mas group partners to grow vegetables so that they can meet their daily vegetable needs and reduce living costs by utilizing existing land using sonic bloom technology. The community service partners trained in this service are 25 partners aged 30-50 years. The methods used are socialization, training and mentoring. The results achieved are an increase in Partners' understanding of sonic bloom technology to 80%, Partner knowledge 98% and Partners' desire to cultivate vegetables with sonic bloom by 100%.

Abstract

Perkembangan pertanian ramah lingkungan diiringi dengan tingginya permintaan produk organik. Jenis limbah rumah tangga bermacam-macam, namun sekitar 75% limbah rumah tangga merupakan sampah organik dan sisanya merupakan sampah anorganik. Sumber limbah terbesar yang dapat menyebar dan berpotensi mencemari lingkungan adalah limbah rumah tangga. Mengolah limbah ini menjadi produk yang bernilai ekonomi tinggi, seperti pupuk organik cair, merupakan salah satu penanggulangan yang dapat dilakukan. Limbah yang paling banyak dihasilkan oleh rumah tangga adalah air cucian beras dapat dimanfaatkan sebagai bahan baku utama dalam pembuatan pupuk organik cair. Kegiatan ini menggunakan metode penyuluhan dan pelatihan bagi ibu rumah tangga dan masyarakat setempat. Berdasarkan hasil evaluasi dari sesi praktek dapat ditarik kesimpulan bahwa kegiatan ini secara keseluruhan berhasil meningkatkan kemampuan peserta dalam pembuatan pupuk organik cair dan cara penggunaannya pada tanaman. Antusiasme peserta terhadap pelatihan terlihat selama kegiatan pelatihan ini berlangsung. Hal ini dibuktikan pada saat pemateri memaparkan data hasil uji coba penggunaan pupuk organik cair pada tanaman.

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

Phosphate solubilizing fungi are fungi that can convert phosphate in soil from compound form (almost insoluble) into ionic form (easily soluble) so that it can be utilized by plants. The purpose of this study was to determine the isolation and characteristics of phosphate solubilizing fungi isolates found in fruit and vegetable peel waste compost. This research was conducted in January 2023 until completion in the Laboratory of the Faculty of Science and Technology, Labuhanbatu University. This research was carried out by isolating fungi from municipal waste compost, characterizing morphology and the ability to dissolve phosphate and molecular identification. Furthermore, the data were analyzed descriptively based on the research results obtained. There were 4 isolates of phosphate solubilizing fungi that were able to form clear zones on Pikovskaya media with different morphological characteristics and ability to dissolve phosphate. The largest clear zone diameter was shown in isolate A3 of 3 cm which is Aspergillus niger fungus.

Abstract

The process of erosion leads to the loss of fertile topsoil and a reduction in the soil's capacity to store and absorb water. At the research site, community oil palm plantations in Tanjung Pasir Village, Kualuh Selatan District, North Labuhanbatu Regency, land clearing was conducted through logging, and in some cases, burning. Subsequent plantation management was carried out without implementing soil conservation measures and while disregarding environmental factors, resulting in soil degradation and productivity decline linked to erosion. This study aims to predict the magnitude of erosion using the Universal Soil Loss Equation (USLE) method, calculate the tolerable soil loss, and analyze the erosion hazard level. The USLE method was applied by calculating the causative factors of erosion: rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), cover management (C), and conservation practices (P). The predicted erosion values were then compared to the tolerable soil loss values to determine the necessity of conservation interventions. The results indicate that the highest predicted erosion value (A) was 521.73 tons/ha/year on plot KS1, while the lowest was 111.09 tons/ha/year on plot KS5. Meanwhile, the tolerable soil loss (TSL) ranged from 43.86 to 64.38 tons/ha/year. Based on this comparison, two classes of erosion hazard were identified: very high and high. Both classes exhibited predicted erosion values far exceeding the permissible limits. Therefore, conservation measures are imperative, one of which involves planting dense Legume Cover Crops (LCC).
