Abstract

Fertilization activities also provide macro and micro-nutrients for plants such as nitrogen, phosphorus, and potassium. The role of the three elements is very important and have mutually supporting functions in plant growth and development. This research aims to observe the effect of different doses of liquid organic fertilizer on the growth of lettuce plants. So, we can provide the best advice for fertilizing lettuce plants. Providing liquid organic fertilizer to 20 lettuce plants using 3 doses mixed with 1000 ml of water for each dose, including: (1) 5 ml dose of liquid organic fertilizer + 1000 ml water for five plants, (2) 10 ml dose of liquid organic fertilizer + 1000 ml of water for five plants, (3) Dose of 15 ml of liquid organic fertilizer + 1000 ml of water for five plants, and (4) Use of control on five plants that were not given POC. The results of the research showed that the effect of giving each dose of liquid organic fertilizer, namely 5 ml, 10 ml and 15 ml, showed the highest growth results, namely at a dose of 15 ml and the lowest was obtained in the treatment without liquid organic fertilizer (control).

Abstract

This research aims to identify potential types of pests that attack horticultural plants at the Agricultural Extension Center (BPP) of Ngingas Village, Krian District, Sidoarjo Regency. This research uses a qualitative descriptive method by collecting data through direct observation, interviews with farmers and BPP staff. The types of plants that are the focus of this research are chilies, tomatoes and eggplant. The research results show that there are three main types of pests that attack horticultural plants in the area, namely whiteflies (Bemisia tabaci), mealybugs (Phenacoccus manihoti), and fruit flies (Bactrocera spp.). Symptoms of whitefly infestation include yellowing leaves and growth of sooty mold due to honeydew excretion. Mealybugs cause leaves to curl and turn yellow with white powder on the undersides of the leaves and stems. Fruit flies cause holes in the fruit, turning brownish in color, and the presence of larvae in the fruit.

Abstract

The rapid advancement of remote sensing technology and Geographic Information Systems (GIS) has substantially enhanced the accuracy, efficiency, and comprehensiveness of spatial data acquisition and analysis. This study investigates land-use patterns within a selected area of Belayung Baru Village, Kertak Hanyar District, Banjar Regency, South Kalimantan, employing high-resolution drone imagery to generate detailed spatial information. A multirotor drone-based mapping survey was utilized, with data processed through Agisoft Metashape and ArcGIS to produce orthomosaic images and thematic land-use maps. The results reveal that the study area encompasses approximately 93.74 hectares, predominantly consisting of rice fields (65.86 ha), residential zones (17.15 ha), and wetlands (6.69 ha). Visual interpretation of drone imagery demonstrates pronounced seasonal contrasts between rice fields and wetlands in terms of spectral tone, texture, and spatial pattern. Furthermore, the dynamic hydrological conditions of the wetland ecosystem substantially influence local agricultural cycles, restricting cultivation to the dry season when the water table recedes. Overall, this study underscores the effectiveness of drone-based geospatial technology in delivering precise spatial mapping outputs that support sustainable land-use management and planning.
