The aim of this study is to ascertain the impact of different forms of manure on the production of elephant grass, as well as the relationship between the types of manure and harvest age on the production of elephant grass. The study was conducted at Tjut Nyak Dhien University's experimental field in the Faculty of Agriculture and Animal Husbandry in Medan. The study was conducted between February and May of 2023. A Factorial Randomized Group Design (RAK) with two treatment factors was employed in the study. First, there are four treatment levels represented by the symbol P (planting medium): P0 (control); P1 (chicken manure); P2 (cow manure); and P3 (goat manure). Harvest Age, represented by the symbol (W), is the second component. It is divided into two treatment levels: W1 (30 DAP) and W2 (40 HSP). The study's findings demonstrated that the number of tillers and wet weight were significantly impacted by the various manure treatment methods. The plant height was significantly affected by the harvest age treatment. The interaction of the two treatments had a very significant effect on the number of tillers and a significant effect on the wet weight. The highest production was obtained in the P3W1 treatment (goat manure; harvest age 30 DAP).In the P3W1 treatment (goat manure; harvest age 30 DAP), the highest output was achieved. Goat manure application had the greatest effect on the plant metrics of fresh weight and tiller count. Harvesting following leveling at intervals of forty days has the greatest effect on plant height metrics. The parameters of the number of tillers and weight wet with P3W1 treatment (goat manure; harvest age 30 days) are most influenced by the combination of manure types and harvest age.

Medicinal plants are plants that contain active substances that can be utilized
as disease healers as well as medicinal properties. The utilization of medicinal
plants has been widely practiced by the Malay community in Mungguk Village.
The purpose of this study was to determine the number of species with medicinal
properties, plant parts, processing methods and the use value of medicinal plants.
This research was conducted from March to April 2023 located in Mungguk
Village, Sekadau Regency, West Kalimantan. This research used semi-structured
interview techniques with sample collection using the snowball sampling method.
The results of the research on potential medicinal plants in Mungguk Village found
35 species in 20 families. The frequency of citation of families with the largest
utilization value was 70% in the Zingiberaceae family, while the lowest was 10%
in the Amaryllidaceae family, Lauraceae family, Malvaceae family, and
Pedaliaceae family. The highest species use value (SUV) was 0.5 and the lowest
was 0.1.

PENGARUH JENIS MULSA TERHADAP PERTAMBAHAN VOLUME AKAR DAN KARAKTER FISIOLOGIS TIGA VARIETAS PADI GOGO

Gogo rice is one of the food crops that has the potential to be developed in national rice is becoming increasingly important, this is due to the decreasing rice field area, while the population growth rate is getting higher. Field experiments were carried out on the land of the Faculty of Agriculture, Islamic University of North Sumatra from May to August 2021. The aim is to determine the effect of mulch type on root volume, plant growth rate and net assimilation rate of gogo rice plants. The research method used was a Factorial Group Random Design with three different types of mulch as treatment, namely without mulch, black plastic mulch, Asystasia gangetica mulch, straw mulch. The varieties used are IPB8, IPB9 and Red Sigambiri. The treatment combination consists of 12 combinations in three repetitions. The results showed that mulch and varietal treatment had a real effect on root volume, while on plant growth rate and net assimilation rate had no real effect.

Long bean plants are a horticultural commodity that has the potential to be developed because they have quite high nutritional and economic value. In order for long beans to grow optimally, organic and inorganic fertilizers can be applied. This research aims to determine the effect of providing organic and inorganic fertilizers and the correct dosage on the growth of long beans. This research used a factorial Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor is the application of Nasa liquid organic fertilizer (LOF) at 4 levels, namely: C0 (0 ml/liter of water/control), C1 (2 ml/liter of water), C2 (4 ml/liter of water) and C3 (6 ml /liter of water). The second factor is the application of NPK fertilizer at 4 levels, namely: N0 (control), N1 (dose 200 kg/ha or 20 g/plot), N2 (dose 300 kg/ha or 30 g/plot), N3 (dose 400 kg /ha or 40 g/plot). The research results showed that Nasa LOF application and NPK fertilizer had a significant effect on plant height at 15 and 30 days after planting (DAP), number of branches at 15 and 30 DAP and flowering age.

Heavy metal pollution in urban soil is an increasingly urgent problem today. High concentrations of heavy metals in soil can cause long-term risks to ecosystems and humans. It is necessary to find a solution to reduce heavy metal pollution, especially through phytoremediation using patchouli plants. Research on patchouli plants was carried out using a non-factorial randomized block design; consists of 1 factor, namely the concentration of the heavy metal Cd which consists of five levels: K0= 0 ppm, K= 85 ppm, K2= 170 ppm, K3= 255 ppm, K4= 340 ppm. Each treatment was made in 3 replications where each experimental unit consisted of 3 plants. Data on essential oil content and uptake of the heavy metal Cd from the results of this study were analyzed using IBM SPSS Statistics 20, then the treatment that showed a real influence on the observed variables was continued with the Duncan's Multiple Range Test (DMRT) at a confidence level of 5%. The parameters observed were root length (cm), root volume (cm3), root wet and dry weight (g), shoot wet and dry weight (g), essential oil content (ml/g), cadmium uptake in the roots and shoots. (ppm). The research results show that patchouli plants are classified as plants that are resistant to heavy metal stress, this can be indicated by their ability to grow and develop well at concentrations ranging from 0 ppm to 255 ppm. Based on the absorbed Cd content, patchouli plants are classified as phyto-extraction plants because they are able to accumulate greater Cd metal in their shoots compared to the Cd content in their roots. Likewise, the production of essential oils produced is not influenced by the concentration of Cd metal.

Seedlings which look prima is a prerequisite for the success of oil palm cultivation. Besides, because of the factors in the pre-nursery genetic, the provision of nutrients in early growth seedlings has an important role performance determine the appearance of the seedlings thoroughly. This study aims to determine the influence of the growth of oil palm seedlings at each concentration of organic fertilizer tithonia and fertilizer of urea for pre-nursery. The experiment was carried out from Oktober 2023 to April 2024 in the Experimental Garden of the Faculty of Science and Technology, the University of Labuhanbatu Rantauprapat with a height of 13 meters above sea level. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The first factor includes the dose of Organic Fertilizer Tithonia (ton/ha) comprising of three standards, namely T₀ = 0 ton/ha, T₁ = 10 ton/ha, T₂ = 20 tons/ha and the second factor was fertilizer dosage Uera which consists of four levels, namely U₀ = 0 kg/ha, U₁ = 100 kg/ha, T₂ = 200 kg/ha, U₃ = 300 kg/ha. The experimental results show that there are significant interactions of organic fertilizer Tithonia with fertilizers urea on plant height (cm) and leaf area of oil palm seedlings (cm2). Treatment of organic fertilizer tithonia 20 tons/ha with fertilizer urea 300 kg/ha yield plant height and leaf area of oil palm seedlings the best for pre-nursery.
