Abstract

The practice of intensive farming systems in corn cultivation with High External Input (HEI) in the form of synthetic chemicals raises problems of ecosystem balance so that national maize productivity remains at 5.1 ton/ha from its potential Yield of 10-12 ton/ha. One of the efforts to increase maize productivity with environmentally friendly principles is the application of silicon fertilization which has the potential to increase the rate of photosynthesis and natural resistance of maize plants. The purpose of this study was to determine the level of Si uptake and accumulation in plant tissues and its implications for corn’s natural resistance, growth, and productivity on several types of Si fertilizers and their application methods. The method to be carried out in this study used an environmental design Splot Plot Design with basic design RCBD with 3 replications and analyzed using Analysis of Variance (ANOVA) followed by 95 % Duncan test (DMRT) if there is a significant difference. The results showed that there was no interaction between the type and method of application with the growth, yield, and natural resistance of plants to pests, but singly affected several observed variables. Silicon fertilization has the potential to increase the uptake rate and content of these elements in plant leaf tissue by application through the roots either leaking or spreading for all types of Si fertilizers although it is not statistically significant. Increasing the Si content in leaf tissue has implications for the relative increase in plant height, especially spray for all types of Si fertilizers, dry weight, number of leaves, leaf area index, and a relative decrease in leaf angle and pest and disease attacks, relatively increasing yield for K2SiO3 and CaSiO3 in all methods. application, as well as the best CaSiO3 in reducing % KA, increasing yield, and % good corncob.

Abstract

One of the essential sub-sectors that should develop to support the agricultural sector is the post-harvest agro-industry. Sederhana is the largest tofu factory in Bukit Peninjauan I village. The factory produces tofu daily to fulfill two traditional markets in Bengkulu City. This study aimed to evaluate the production cost, profit, income, R/C ratio, and added value at every production process. The study had been carried out in the Sederhana tofu factory in Bukit Peninjauan I village, Sukaraja sub-district, Seluma District, Bengkulu Province in November 2020. The data used in this paper were both primer and secondary data. The business qualification was determined by analyzing total cost, profit, income, R/C ratio, and added value. The results of this research showed that the Sederhana tofu factory had good quality business qualifications. For every 400 kg of soybean per production per day, it needed the total cost of Rp. 5,381,056.82. Meanwhile, the profit was about Rp. 6,600,000, and the income reached Rp. 1,218,943.18. Thus, the R/C ratio was 1.23 which was profitable. Besides, the added value was Rp. 6,433.34 per kg of soybean. However, the added value was the gross value since it contained labor income and share.

Abstract

Tithonia (Tithonia diversifolia) is an invasive weed plant commonly grown in Asia and Africa, including in Bengkulu Province. As a weed, this plant is rarely used in agricultural production though it has great potential to be used as the primary source for organic fertilizer. This study aimed to evaluate the effects of doses and application frequency of organic fertilizer made of tithonia on the growth and yield of sweet corn. An experiment had been carried out in Bengkulu Province from September 2019 until February 2020. The research comprised three levels of organic fertilizer rates and two levels of application frequencies replicated thrice in Completely Randomized Design with LSD 5%. The results showed that tithonia organic fertilizer did not influence the plant heights of sweet corn but had significant effects on the dry weight of shoot and root. Tithonia organic fertilizer had fulfilled the minimum requirement as organic fertilizer as obliged in the national organic standard (SNI). The highest yield of sweet corn was obtained by applying 20 t/ha of tithonia organic fertilizer in the twice split application.

Abstract

The area of peatland has the potential to be used as agricultural land, but the potential of this peatland has challenges that are not easy to manage in a sustainable manner. Improper management can cause peat soils to experience drought stress. A technological approach that can be used to optimize the use of peat soils experiencing drought stress in maize can be done by applying a biofertilizer formulation. The purpose of this study was to obtain a biofertilizer formulation to increase the growth and production of maize under drought stress conditions on peat soil. This research was conducted in the experimental garden of Bina Insan University, Lubuk Linggau The design used in this study was a completely randomized block design with 2 treatment factors, namely the first treatment factor for biological fertilizers, namely H0: without Mycorrhizae, H1: Mycorrhizae + Petrobio, H2: Mycorrhizae + Agrozeabiochar, H3: Mycorrhizae + Pugam. The second treatment factor was the intensity of watering, namely P1: Watering once a day, P2: Watering once in 3 days, P3: Watering once in 5 days, P4: Watering once in 7 days. The treatment factor was repeated 4 times to obtain 64 plants. The results of the study on the application of biofertilizer formulations after being analyzed at the 5% level showed significantly different results in plant height, root dry weight. Biofertilizer formulations that can increase the resistance of maize plants on peat soils under drought stress were shown by the treatment of the biological fertilizer formulations Micorrhiza + petrobio (H1) and Mycorrhiza + pugam (H3).

This study aims to see the growth and yield of hybrid red chili with various varieties and the dose of NPK Mutiara fertilizer and to see the interaction between hybrid red chili varieties and the dose of NPK Mutiara fertilizer. This study used a factorial randomized block design (RAK) consisting of 2 factors, namely the red chili variety factor (V) which consisted of 3 types: V1 = Kastilo F1, V2 = Laju F1, and V3 = Lado F1. The combination factor of NPK fertilizer (P) consisted of 3 levels: P1 = 19 g/plant, P2 = 23 g/plant, and P3 = 28 g/plant. Parameters observed included flowering age (Days), stem diameter (cm), number of chilies per plant (fruit), chili length (cm), chili diameter (cm), fresh chili weight per plant (gr), and fresh fruit weight. per plot (gr). The results showed that hybrid red chili varieties had a significant effect on the parameters of the number of chilies per plant, the weight of fresh chilies per plant, and the weight of fresh chilies per plot. The best results were obtained in the V2 treatment (F1 Laju). The dose of NPK Mutiara had a significant effect on the parameters of flowering age and chili length. The best results were obtained in the P3 treatment (28 g/plant). The interaction of hybrid red chili varieties with NPK Mutiara fertilizer had a significant effect on chili length parameters and the number of chili peppers per plant. However, it had no significant effect on flowering age, stem diameter, chili diameter, fresh chili weight per plant, and fresh chili weight per plot. The best interaction was found in the V2P3 treatment (F1 rate + 28 g/plant).

Abstract

Previous research has found a new type of herbicide made from fermented coconut water as the main raw material, containing organic materials, microorganisms, and is environmentally friendly. A series of tests need to be done to see its effectiveness. This study aims to determine the best formulation of herbicide in controlling weeds on land weeds and aquatic weeds in multiple locations. The experiment used a randomized block design, consisting of nine treatments of herbicide formulation (Unihaz) with three replications. The treatments were Unihaz 1, Unihaz 2, Unihaz 3, Unihaz 4, Unihaz 5, Unihaz 6, Unihaz 7, Unihaz 8 (glyphosate 2 kg ha-1) and Unihaz 9 (fermented coconut water). The results of the study concluded that the Unihaz 7 formulation was effective in controlling weeds both in dryland (land weeds) and in wetlands (water weeds) at various altitudes, and could control weeds above 90%. The herbicide formulation of Unihaz 7 was better at controlling weeds in paddy fields than the use of glyphosate at a dose of 2000 g ha-1
