Abstract

Modeling science has been applied by many advanced countries in many fields, such as geology, meteorology, climate change, crop productivity, environment, erosion, and landslide. The crop model simulates the processes of agriculture. The writing of this article is descriptive qualitative using the Systematic Literature Review (SLR) method. So far, each model has its advantages and disadvantages but generally is based on the physiology of the growth and development of crops in relationship with soil, climate, solar radiation energy, and limiting factors to plant growth. There have been many models for rice that can forecast yield and biomass or predict future climate change dynamics. Meanwhile, many models such as DSSAT, AquaCrop, Oryza, APSIM, EPIC need more data to operate their modeling, which in many cases, data is not readily available. In this review, we would like to introduce the model “SIMPLE” which includes only thirteen parameters and four of which describe cultivar characteristics. Another advantage of “SIMPLE” is that it can be adapted for many crop species and added variable modules such as nutrient dynamics, water stress, temperature stress, or pests. It is entirely open source based on R programming, but limitations still exist that have been mentioned in the review.

Abstract

One of the factors hindering the development of upland rice cultivation among annual crops is the limited number of shade-tolerant upland rice varieties. It is very important to assemble shade-tolerant upland rice varieties with high yields. The purpose of the study was to determine the effect of shade on the growth and productivity of five genotypes of upland rice. This research was carried out in the experimental garden of the Faculty of Agriculture, the Islamic University of North Sumatra with an altitude of 25 m above sea level, from June to December 2020. The research design was split-plot and repeated three times. The main plot of shade treatment consisted of two levels, namely no shade (0%) and shade treatment (70%). The sub-plots were five genotypes of upland rice in Deli Serdang and two shade-tolerant varieties. Shade treatment affected the growth and productivity of five genotypes of upland rice in Deli Serdang District (Sialus, Arias, Ramos Merah, Silayur, and Sirabut) and two shade-tolerant varieties (Rindang 1 and 2). Two genotypes of upland rice were obtained, namely Silayur and Sirabut which were more shade tolerant, based on flowering age, harvest age, and grain weight per clump. When compared with Rindang 1 and 2 varieties, the two genotypes of upland rice were the same or more tolerant.

Abstract

Lignin reduced the adhesion between the polymeric matrix and natural reinforcement in composite materials by its hydrophobic characteristic. Removal of lignin can be a solution to improve fiber function in composite use. This study aimed to determine the degradation of lignin at different times of pulping. The soda process was conducted at 60, 70, 80, 90, and 100 minutes of pulping using heat in a room atmosphere. Yields, lignin content, and lignin spectrum (FT-IR analysis) were measured.  The result showed the highest degradation of lignin was in 100 minutes of pulping with 80.34% lignin degradation and 3.57% lignin left in fibers. However, the yield of fibers decreased with increasing pulping time due to lignin removal. 100 minutes of pulping time showed the highest loss of fiber yield. This study showed the best pulping time for kapok fiber is 100 minutes with 3.57 % lignin remaining in the pulp.

Abstract

Potato (Solanum tuberosum L.) has been classified as major source of carbohydrate along with rice, wheat, and corn. As for other crops, potato’s growth and yield are always subject to weed interference. An experiment has been conducted to study the effect of indigenous rhizobacteria to promote the growth and yield of potato var. Cingkariang and weed population at Nagari Pakan Sinayan, Agam District, the Province of West Sumatra. The experiment used a completely randomized design with seven treatments and three replications. The treatments was rhizobacteria indigenous to potato farm at Nagari Pakan Sinayan i.e SWL2.2, Ag2L2S3.3, Ag2L2S4.2, Ag3L3S3.1, Ag3L3S5.1, Ag4S5.2, and one group of without the isolate. Data were analysed with analysis of variance and mean separation following DNMRT at 5%. Results demonstrated that indigenous rhizobacteria promoted plant height, number of branches, and the weight of potato tubers. The rhizobacteria also resulted in changes in weed population. Ten weed species were found prior to the experiment as follows: Ageratum conyzoides L.,  Alternanthera philoxeroides (Mart.) Griseb., Andrographis paniculata (Burm.f) Nees, Bidens pilosa L., Cyperus rotundus L., Crassocephalum crepidioides (Benth.) S. Moore, Eleusine indica L., Echinochola colona (L.) Link, Galinsoga quadriradiata Ruiz & Pav., dan Paspalum commersonii Lamk. However, three new weed species emerged during the experiment. They are Amaranthus spinosus L., Portulaca oleracea L., and Paspalum conjugatum P.J.Bergius indicating changes in weed population.

Abstract

The process of producing starch film using the casting method required a significant amount of time to obtain the desired film product. Therefore, this study was conducted to reduce the production time required for the starch film. The study used five varieties of starch: bengkoang starch, talas starch, glutinous rice flour, wheat flour, and MOCAF flour. The process involved homogenizing the starch and glycerol mixture utilizing a stirrer, followed by heating using a microwave and a compression process to accelerate the evaporation of water in the starch film. For the final drying stage, samples that had gone through this process were dried using a cabinet dryer. The result showed that the developed method of starch film requires only 60 minutes of the time needed compared to conventional casting method, which usually takes 5-48 hours. Furthermore, it was observed that starch film production using glutinous rice flour resulted in the highest tensile strength.

Abstract

Indole‐3‐acetic acid (IAA) is an essential phytohormone that controls a variety of plant growth mechanisms. Bacteria can produce IAA to stimulate plant growth, with its production influenced by the culture conditions. Serratia plymuthica UBCF_13 is recognized as an IAA‐producing bacterium, exhibiting maximum IAA production in a yeast medium comprising yeast extract, sucrose, K2HPO4, MgSO4, NaCl, and CaCO3. However, prior studies optimizing individual inorganic salt components indicated minimal impact on IAA synthesis within this medium. This study aimed to eliminate the unnecessary inorganic salt components and the medium was then applied to investigate the IAA biosynthesis pathway and the plant growth‐promoting assay. The elimination assay consisted of yeast sucrose medium devoid of K2HPO4, MgSO4, NaCl, or CaCO3, and yeast sucrose medium containing only MgSO4 and CaCO3. Various indole compounds were then added to the revised medium composition to investigate the IAA biosynthesis pathway of UBCF_13 using high‐performance liquid chromatography (HPLC). Furthermore, the effect of UBCF_13 culture supernatant, cultivated in the new medium, on chili plant growth was evaluated. The highest IAA production (138.8 µg/mL) was observed in the yeast sucrose with CaCO3 and MgSO4 (elimination of K2HPO4 and NaCl). The presence of indole‐3‐acetamide (IAM) compound from the medium extracts, supplemented with multiple indole compounds, revealed that UBCF_13 may use the IAM pathway. The application of UBCF_13 supernatant enhanced the shoot, root length, fresh weight, and germination time of chili seeds by 37.7%, 49.3%, 204.3%, and 38.6%, respectively. This study demonstrated that eliminating K2HPO4 and NaCl provided a new culture medium composition conducive to IAA production by UBCF_13. Moreover, the UBCF_13 extract has the potential to promote plant growth.

Abstract

Maize is a second important food crop, its yield is the raw material for the feed industry. As for other crops, maize can not avoid weed association and interference. Weed may cause farmers’ economic loss. An experiment to determine the efficacy of thiencarbazone methyl+isoxaflutole herbicide and its effects to control weeds and maize yield was conducted from October 2022 to February 2023 at Ultisol of Universitas Andalas, Limau Manis, Padang. The experimental units were laid out according to a completely randomized block design (CRBD) with 10 treatments and three replications. The treatment was different types of weed control namely: no weeding, various doses of herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 i.e 250 mL ha-1, 300 mL ha-1, 350 mL ha-1, and 400 mL ha-1 applied at 2 and 10 DAP, respectively, and manual weeding. Herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 effectively controlled Erechtites valerianifolia, Oxalis barrelieri, and Asplenium rhizophyllum. Herbicide at 350 mL ha-1 applied dose at 2 DAP reduced weed dry weight per m-2 as much as 93% at 6 WAP. Weed control by herbicide application increased 72.20% of maize yield per ha compared to the no-weed-control treatment group without causing phytotoxicity on maize plants.ABSTRAK Tanaman jagung merupakan tanaman pangan penting kedua dan menjadi bahan baku industri pakan.

Abstract

Sorghum is a potential alternative food source due to its high carbohydrate, fiber, and protein content, which surpasses that of rice, as well as its greater adaptability to marginal land and dry weather conditions. However, sorghum productivity is often hindered by suboptimal fertilizer use, necessitating additional solutions like biostimulants. Seaweed-based biostimulants, such as Padina minor, hold promise in enhancing plant growth by stimulating nutrient absorption, improving resistance to abiotic stress, and enriching soil quality. This study aimed to evaluate the effectiveness of P. minor extract in increasing chlorophyll levels in sorghum plants. The experiment was conducted using a Completely Randomized Design (CRD) with varying concentrations of P. minor extract (20%, 30%, and 40%) and application frequencies (1, 2, and 3 times). The research results showed that (1) a concentration of 20% with administration of the extract once gave a significant increase in chlorophyll levels compared to other concentrations and frequencies; (2) administration of biostimulants in low concentrations and with fewer administration frequencies has proven to be more effective; (3) higher concentrations and frequencies of biostimulants can cause toxicity to plants; (4) the use of P. minor extract as a biostimulant can be a sustainable alternative in agricultural practices to improve the quality and productivity of sorghum.

Abstract

Giant false sensitive plants (Mimosa invisa Colla) and giant sensitive plants (Mimosa pigra L.) are invasive plant species in the tropics and native to America. They are widely distributed in different ecosystems and soil types. Apart from being considered woody shrub weeds, these plant species can be used as herbal medicine for their antioxidant activities. An experiment to study the antioxidant activities and phytochemicals of M. invisa and M. pigra grown at 200 m from the coastline and close to the riverbank (riparian abandoned land) was carried out from March to November 2023. Weed leaves were collected as purposive randomized sampling from different terrestrial habitats in the City of Padang, West Sumatra. Antioxidant activity was identified according to a 2-2-diphenyl-1-picrilhydrazil (DPPH) radical-scavenging assay, and phytochemical compounds were identified qualitatively. Results demonstrate that M. invisa had mild antioxidant activity and M. pigra had strong antioxidant activity. The IC50 values for M. invisa grown at 200 m from the coastline and at the riverbank were 121.3 ± 11.5 and 105.6 ± 2.90 ppm, respectively. The IC50 values of M. pigra grown at 200 m from the coastline and at the riverbank were 80.6 ± 15.9 and 85.1 ± 9.03 ppm, respectively. Phenolic, saponin, and steroid were detected in all weeds grown at different habitats. However, alkaloids and terpenoids were not detected. Interestingly, flavonoid was not detected in the leaves of M. pigra grown at the riverbank.
