Abstract

ABSTRACT : Groundnut (Arachis hypogaea L.) is one of the most widely cultivated commodities by farmers in Bengkulu Province after rice, cassava, corn, sweet potatoes and soybeans. The amount of peanut production in Bengkulu Province can be increased by increasing the area of ​​land and increasing productivity through the use of superior seeds and good care. The harvested area of ​​peanuts in Bengkulu Province in 2014 reached 4,535 ha with a total production of 4,612 tonnes (BPS 2015). Increasing the amount of production and harvested area will also increase the number of peanut products offered. This research was conducted from August to November 2022 at the Planting House of Pat Petulai University, Dwi Tunggal Village, Curup District, Rejang Lebong Regency, Bengkulu Province, with an altitude of 620 meters above sea level. The method used in this study was a completely randomized design (CRD) which consisted of 4 treatment levels. The results of the analysis of variance in the treatment of shallot skin extract did not have a significant effect on the variable number of flowers, number of leaves, and plant height. While the treatment of shallot skin extract had a significant effect on the variable number of pods (7.15 pods) and fresh weight (8.6 grams). The treatment of shallot skin extract had a very significant effect on dry weight (15.19 grams). The application of shallot skin extract effectively increased the yield of peanut plants, because it increased the number of pods, fresh weight, and dry weight of plants. At a concentration of 45 ml/liter of water, shallot skin extract gave the best results on the variable number of pods and fresh weight on the growth and yield of peanuts. Based on the results of research that has been conducted regarding the application of shallot skin extract to the growth and yield of peanut plants, the authors suggest the use of shallot skin extract at a concentration of 45 ml/liter of water in peanut cultivation in areas with an altitude of 620 meters above sea level.

Abstract

ABSTRACT :Curup local ambon bananas are a leading commodity in Rejang Lebong district. Therefore it is necessary to maintain its genetic resources so that they do not become extinct. Tissue culture technique is the most modern method of propagation because it can grow uniformly, is free from pests and diseases, and produces quickly. However, maintenance of tissue culture seedlings at the acclimatization stage needs attention. Therefore researchers will examine the treatment of media and local banana varieties Curup on growth. The research was carried out in the plastic house at Pat Petulai University from December 2022 to March 2023. The materials used were yellow and green Ambon banana seeds resulting from tissue culture, a fungicide with an active ingredient of 80% monkozeb. This study aims to determine the best media and varieties that grow best at the acclimatization stage. The design of this study was a completely randomized design (CRD) with two factors, namely the planting medium and the local Ambon banana variety Curup. Each treatment was repeated 3 times with 2 plant samples so that there were 36 experimental units. Observations were made at the end of the study on all observation variables. The data obtained was then analyzed using the Analysis of Variance (ANOVA) with a level of 1% if there is a difference then it will be tested further with the BNT Test (Smallest Significant Difference). The results showed that good planting media treatment was seen in soil + coffee husk media because it could increase the growth of plant height by 41.02 cm, the number of leaves was 6.92 strands, the stem diameter was 12.3 mm. However, the variable leaf width and leaf length showed good growth in soil + rice husk treatment. The longest leaf width is 12.35 cm and the length of the leaf is 13.51 cm. A good variety is ambon kuning because it can increase the leaf width by 11.65cm. The soil + coffee husk planting media is more dominant in influencing several variables because of the high nutrient content in the media. It can be recommended to Ambon kuning farmers to give good results.

Abstract

Abstract : Pepper is a vine and has a single green leaf with a stem height of almost 10 meters. Bengkulu Province is one of the pepper producers in 2021 of 1,850 tons/year with a percentage of 1.31%, of course it cannot meet market demand which is quite high. The decline in pepper production is thought to be caused by several factors, one of which is the lack of good pepper plant seeds available because most farmers plant pepper vines directly on the land without any treatment so that farmers have difficulty cultivating pepper plants. Pepper seeds can be obtained from generative or vegetative propagation. Propagation by cuttings is the recommended method in pepper nurseries. Pepper cuttings have poor roots, so a growth regulator is needed to stimulate the roots. The alternative is by giving Growth Regulatory Substances. One ZPT that can be used to accelerate the growth of pepper plant cuttings is mung bean sprout extract. This research was conducted from February to April 2023, in Taba Tebelet Village, Kepahiang District, Kepahiang Regency, Bengkulu province. This study used a completely randomized design (CRD) with 24 treatment combinations, each of which was repeated three times. Total plants used in the study (K X S X U) = (6X4X3) = 72 plant cuttings. Variable observations were growth percentage, shoot length, root length, number of leaves, stem diameter, and number of shoots. Observational data were analyzed statistically using analysis of variance (ANOVA). The results of this study indicated that the combination treatment of mung bean sprout extract concentration and type of tendrils had a significant effect on the growth of pepper plant cuttings. However, in the single treatment the concentration of sprout extract and the single treatment of the type of tendrils had no significant effect on the growth of pepper plant cuttings.

Abstract

Peanut productivity in Bengkulu Province in 2021 is 2,498 tonnes/ha. However, the productivity of peanuts is still low compared to the average national productivity, which has an average production of around 3,595 tonnes/ha. Soil fertility is an important factor for farming. For this reason, it is necessary to take appropriate actions, one of which is to improve soil nutrients, one of the actions taken is liming the soil. Apart from that, fertilization is also important to note in increasing peanut production by using pearl NPK doses. Pearl NPK is one of the inorganic fertilizers. This study aims to determine the best dosage of dolomite and pearl NPK fertilizer on the growth and yield of peanuts. This study used a randomized block design (RBD) using 2 treatment factors with 4 levels and 4 repetitions, each repetition consisting of 4 plants. Then 16 combinations were obtained, with the total plants used, namely: D×N×T×U= 4×4×4×3= 192. The data obtained were analyzed using ANOVA and continued with 5% DMRT. The results showed that the dose of dolomite was 200 grams and 50 gram pearl NPK fertilizer has an effect on the observed variables, namely plant height, number of leaves, number of flower strands, number of pods, wet weight, and dry weight. Based on the results of ANOVA, it can be concluded that dolomite has an effect on the growth and yield of peanuts, NPK pearl fertilizer treatment has an effect on the growth and yield of peanuts, the interaction of dolomite and NPK pearl fertilizer has an effect on the growth and yield of peanuts.

Abstract

Foot and Mouth Disease (FMD) is perhaps one of the most detrimental diseases in cattle farming. With the aim of understanding the effect of this disease on the body tissues of cattle, this research carried out precise writing research. This study aims to provide a comprehensive picture of changes in body tissue in cows affected by FMD. Writing concentration techniques are used to distinguish, collect, break down and combine important written sources. The data found in this examination comes from logical articles, books, and exploratory reports covering the period 2000 to 2021. Writing views are displayed through logical information bases such as PubMed, Google Researcher, and IEEE Xplore, using appropriate slogans. The results of this study reveal that FMD disease in cattle causes serious histopathological changes in body tissue. The first sores occur on the mouth, lips, and feet, with the development of characteristic vesicles. The component of the spread of FMD infection in the bull group is also concentrated from top to bottom, including through the circulatory system and lymphatic system. This includes the production of antibodies and safe cells that function to fight infection. However, several variables, such as hereditary variation and stress, can influence the severity of disease in dairy cattle. This study assumes that a top-down understanding of body tissue changes in cattle affected by FMD is important for progressing control systems, preventing infection, and further examination efforts. This information also provides input for efforts to maintain the health of dairy cows and the continuity of the livestock industry. This study provides a foundation for a better understanding of FMD in bulls and encourages future exploration of additional interesting immunization improvements and preventive measures.
