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.

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.

Optimizing the use of plantains depends not only on increasing its production but also on improving post-harvest operations before it reaches the final consumer. Proper management during the post-harvest period is better than using advanced technology. Themain objective of this study is to preserve plantains in a traditional cold pot in the locality of Man. To carry out this experiment, we used a device consisting of a large pot containing a small pot and clay filling the space between the pot and the large pot. This device, commonly known as the “desert fridge”, has enabled us to obtain green lifespans for the Corne 1 and Agnrin cultivars of between 15 and 22 days. During our conservation, the physical and biochemical characteristics of plantains were determined. The analyzes revealed a slight lower mass loss: Horn 1 (6.85 ±0.2%) and Agnrin (7.4 ±0.5%), loss of firmness and dry matter, reduction in starches and dietary fiber. But on the other hand, an increase in the content of reducing sugars, the transfer of the color of the skin from green to yellow of the stored plantains.

communities in using natural resource areas. This study aims to determine the advantages of the agroforestry system, which is a mixture of albizia and mountain rice. The agroforestry system gave the best growth of albizia after three years. The mean Annual Increment diameter and height of 3-year-old albizia plants in agroforestry systems were 14.02 cm and 7.19 m, respectively. The agroforestry system is also believed to reduce the number of forest damage because local people who originally stole forest wood have begun to be diverted to more productive planting activities with an intensification pattern. The involvement of local communities in business activities based on natural resource management in various forms is part of the concept of corporate social responsibility. The agroforestry system is superior to the intensive monoculture pattern because it can absorb more labor and increase the income of local communities, creating cooperation and togetherness between companies. Furthermore, an agroforestry system can reduce the number of forest and land fires because local communities, as arsonists, will help protect their land and crops.
