Introduction: This study aims to analyze the financial feasibility and identify the influence of total production, planting area, and farmer identity (age, education level, farming experience, number of family dependents) on the income of lowland rice farmers in Selubuk Village, Air Napal District, North Bengkulu Regency. Methods: This study used a quantitative approach with a survey method on 29 farmer respondents selected from 97 farmer families using the Slovin formula. Primary data were collected through questionnaires and interviews, while secondary data were obtained from related agencies. Data analysis included cost-revenue analysis (R/C ratio) and multiple linear regression analysis. Results: The results showed that lowland rice farming in Selubuk Village was financially feasible with an R/C ratio value of 3.39. The regression analysis results indicated that simultaneously, total production, planting area, age, farming experience, education level, and number of family dependents had a significant effect on farmer income (Sig. F = 0.000). Partially, the variables of total production, planting area, farming experience, and education level had a positive and significant effect on farmer income (p < 0.05). However, a multicollinearity problem was detected between the total production and planting area variables, which needs attention in the interpretation of their individual coefficients. The variables of age and number of family dependents did not have a significant effect on farmer income (p > 0.05). Conclusion: In conclusion, lowland rice farming in Selubuk Village is profitable, and income improvement can be focused on production factors, experience, and increasing farmer education capacity, considering the close relationship between production and land area.

This study aimed to evaluate the effectiveness of various herbicide formulations based on fermented coconut water, acetic acid, ethanol, glyphosate, and salt against weeds in open fields. The study used a Randomized Block Design with 9 formulations and 3 replications. Observed variables included dominant weeds, dead weed area, live weed population, dry weight of live weeds, and chlorophyll degradation. The results showed that four types of weeds dominated the field (96%): Paspalum conjugatum, Mimosa pudica, Cyperus rotundus, and Chrysopogon aciculatus. Herbicide formulations significantly suppressed weed growth. Formulations 3 and 9 proved to be the most effective. Further development of Formulations 1, 3, 4, 5, 7, and 8 is recommended.

This research aims to determine the effect of types of soil processing and potassium dosage on the growth and yield of sweet corn plants in ultisol subsoil soil. The experiment used a Split Plot Design with 3 replications. The main plot is a type of land cultivation consisting of 3 levels, namely: no tillage, minimum tillage, maximum tillage. As a subplot, the dose of potassium fertilizer consists of 4 levels, namely: without fertilizer (control), dose 75 kg/ha, dose 150 kg/ha, and dose 225 kg/ha. The research data was analyzed using Diversity Analysis to find out whether the treatment had a real effect or an insignificant effect. If the results of the analysis have a real or very real effect, then continue with the Duncant's Multiple Range Test (DMRT) at the 5% level.This research concluded that: maximum tillage had a significant effect on plant height at 8 wap, number of leaves in the flowering phase, and ear circumference, and was very significant on leaf width, weight of husked cobs per plant, and weight of husked cobs per sweet corn plant planted in ultisol sub soil. The dose of potassium fertilizer of 225 kg/ha had a real and very significant effect on the variables of plant height at 4 wap, 6 wap, 8 wap, weight of cobs with husks and weight of cobs without husks. gave plant heights of 4 wap, 6 wap, 8 wap, highest cob weight with husks and cob weight without husks in sweet corn planted in Ultisol subsoil soil. The interaction of the type of soil processing and potassium dose influences the weight of cobs with husks per plant and the weight of cobs without husks per plant. The maximum type of tillage and a potassium dosage of 225 kg/ha provide the highest weight of husk-free cobs per plant and the highest weight of husk-free cobs per plant.

Sengon Buto Seeds (Enterolobium cyclocarpum) have hard and thick seeds making it difficult to germinate. Efforts to break sengon buto seed dormancy can be done by using hard acids, one of them is hydrochloric acid (HCl), which can soften the hard surface of the seed coat. This study aims to obtain the concentration and the soaking time of hydrochloric acid in accelerating the breaking of dormancy of sengon buto seeds. The design used in this study was a completely randomized design (CRD) factorial pattern with 3 replications. The first factor studied was the concentration of hydrochloric acid (HCl) (K) consisting of 3 levels, namely: K1 = 1% (1 ml/l water), K2 = 2% (2 ml/l water) and K3 = 3% (3 ml/l water). The second factor is soaking time (L) consisting of 3 levels, namely: L1 = 6 hours, L2 = 12 hours and L3 = 18 hours. The parameters studied were germination capacity, germination speed, germination uniformity, vigor index and seedling dry weight. The results showed that the concentration of hydrochloric acid (HCl) had a very significant effect on the germination capacity and the germination uniformity of sengon buto seeds, had a significant effect on the germination speed and seedling dry weight. However, it did not have a significant effect on vigor index. The hydrochloric acid concentration of 3% (3 ml/l water) could break the seed dormancy and increase the germination. The soaking time did significantly affect the germination capacity and the germination uniformity. However, it did not have a significant effect on germination speed, vigor index, and seedling dry weight of sengon buto seeds. The best soaking time for sengon buto seeds is 12 hours to break their dormancy. There was interaction between HCl concentration and soaking time on germination uniformity variables. Treatment with hydrochloric acid concentrations of 3% (3 ml/l water) and 12-hour soaking time gave a maximum germination uniformity of 44%. Key words: dormancy, hydrochloric acid, seed

Oil palm is a strategic commodity that plays a vital role in Indonesia's economy, but its productivity is often hindered by weed infestation. Chemical weed control commonly relies on synthetic herbicides, which pose environmental risks. This study aims to evaluate the effectiveness of a new natural-based herbicide formulation consisting of fermented coconut water, ethanol, acetic acid, salt, and low-dose glyphosate in immature oil palm plantations. The research employed a single-factor Randomized Complete Block Design (RCBD) with nine formulation treatments and three replications. Vegetation analysis revealed three dominant weed species in the experimental area: Borreria alata, Ageratum conyzoides, and Asystasia gangetica. The results indicated that all herbicide formulations were able to suppress weed populations and dry weight, although the differences were not statistically significant. Numerically, Formulation 8 (F8) provided the best results, achieving a weed mortality rate of up to 99%. In contrast to previous formulations requiring high application volumes (35–50 L/ha), this new formulation is more efficient at a dosage of 4–6 L/ha. This formulation works synergistically, is environmentally friendly, and has the potential to support sustainable agricultural practices
