Abstract

In this study, the inoculation effect of earthworms Pontoscolex corethrurus on celery growth (Apium graveolens L.) has been carried out in red-yellow podzolic (RYP) soils. The research studied in a pot experiment using a completely randomized design (CRD) with 6 (six) treatments and 3 (three) replications. One-pot consists of 4 (four) plants. The treatments carried out were as follows: I0 (without inoculum of earthworm), I1 (inoculum of 5 earthworms pot-1), I2 (inoculum of 10 earthworms pot-1), I3 (inoculum of 15 earthworms pot-1), I4 (inoculum of 10 earthworms pot-1) and I5 (inoculum of 25 earthworms pot-1). Observation parameters were the number of tillers clumps-1, fresh biomass clumps-1 (g clump-1), and root volume (mL). The observations were statistically analyzed using variance (one-way ANOVA) and followed by the Duncan Multiple Range Test (DMRT) with a level of 5%. Treatment I5 gave the best results on celery crop in all parameters, i.e., 20.33 tillers per hill; fresh biomass per clump 113.93 g; and a root volume of 10 mL. The results showed that earthworms' inoculation into RYP soils significantly affected all parameters. There was also an increase in pH in each treatment that was inoculated with earthworms.

Abstract

Sourdough bread is known to have health benefits due to its fermentation process using lactic acid and wild yeast. It can improve the taste, texture, shelf life, and nutritional content of bread as a functional food. In this study, sourdough was made from fermented papaya with varying fermentation times of 4, 5, and 6 days. The substrate was fed five times to strengthen the sourdough, resulting in a robust enough mixture to develop the dough. The resulting sourdough was used to create sourdough bread with a 30% sourdough concentration. The fermentation time impacted the quality of the sourdough, with results showing that sourdough became increasingly active as fermentation time progressed. The best sourdough was obtained from a six-day fermentation period, with a pH of 3.60 and a total plate count of 1.70 × 104 CFU/ml. The best donuts were produced using the sourdough that had been fermented for six days, with an almost perfect score of 3.9 out of 4 for all aspects, including color, aroma, taste, and texture. Using this sourdough resulted in a significantly longer shelf life; no mold appeared until the eighth day of storage at room temperature. The moisture content of the donuts was measured at 4.57%. This study demonstrates the potential benefits of using sourdough made from fermented papaya to improve the quality and shelf life of sourdough bread while also providing potential health benefits.

Abstract

Microalga is single cell organism that can live by photosynthesize resulting biomass and other secondary product such as protein, carbohydrate, and lipid by utilizing nutrients in wastewater. This study aims to get the data about the effect of additions of tofu liquid waste to the growth and increase of lipid content in the microalga that cultivated in tofu liquid waste media. Microalga were cultivated by variations in tofu liquid waste adding. The variations are 0,45 liter in every day, 0,9 liter in every two days, and 1,35 liter in every three days. Microalga growth were measured by an object glass, the amount of cell density in every square field calculated using tomacytometer with hand counter where observed under optical microscope. Total lipid content were gained by employ Bligh-dyer methode. The results of this study show the highest specific grow rate of Chlorella sp is 0,08692/day accounted from tofu liquid waste addition in every three days. The highest lipid content is 40,88 % which gained from tofu liquid waste addition in every day. Under unfavourable condition microalga will accumulate more lipid so that increase it lipid content. The highest chemical oxygen demand (COD) removal is 575 mg/mL.

Abstract

Amid escalating concerns about pesticide residues in agricultural product, this study conducts a meticulous comparative analysis of pesticide residue profiles in locally grown rice, aiming to contribute essential insights for informed decision-making in agriculture. The overarching problem addressed involves identifying pesticides in rice from conventional and sustainable farming and understanding their potential environmental and health implications on food safety. Utilizing HPLC/MS-MS, the research discerns a notable absence of over 500 pesticide types in rice cultivated according to good agricultural practices (GAP). Conversely, rice from fields deviating from GAP guidelines reveals the presence of 7 pesticide active ingredients, with 2 exceeding globally established residue limits by twice the recommended amount. Notably, bifenthrin and tebuconazole, uncommonly used in the last one years, are identified. This study underscores the urgency of adhering to sustainable agricultural practices for the safety and quality of rice, offering critical insights for future research. It not only contributes to current knowledge but also emphasizes the global necessity of safe agricultural practices to safeguard our food supply.

Abstract

Leeks (Allium porum L.) have many health benefits for the human because the fiber, folic acid, calcium, potassium, and vitamin C content is relatively high in it. A study was conducted to determine plant growth regulators' (PGRs) response from shallot extract to leek crops. This study aimed to test the effectiveness of PGR from shallots at the best concentration on the growth and production of leeks. This research was performed experimentally using a non-factorial Completely Randomized Design (CRD) with five treatment levels and four replications. Each plot consists of 4 (four) plants and 2 (two) samples. The treatments were: Z0= control (without PGR), Z1= 7.5 mL of PGR shallot extract, Z2= 15 mL of PGR shallot extract, Z3= 22.5 mL of PGR shallot extract, and Z4= 30 mL of PGR shallot extract. In this study, it was found that giving PGR shallots extract to leek crops had a significant effect on the parameters of plant height, number of leaves, number of tillers, and fresh biomass. The best concentration was at a concentration of 30 mL of PGR shallot extract or Z4 treatment for all observation parameters, i.e., plant height 57.25 cm; the number of leaves 17.75 leaves; the number of tillers 5.75 tillers per hill; fresh biomass per clump 23.75 g. Z0 treatment without PGR shallot extract gave the lowest results for all parameters, such as plant height, number of leaves, number of tillers, and fresh biomass.

Abstract

This study aims to analyze the sustainability level of the coconut farming system in Indragiri Hilir Regency using a multistakeholder approach and the SAFA (Sustainability Assessment of Food and Agriculture Systems) framework. The analysis covers four sustainability dimensions: economic, environmental, social, and governance. Data were collected through Likert-scale questionnaires, interviews, and focus group discussions (FGDs) involving various stakeholders such as farmers, traders, cooperatives, village governments, and related government agencies. The results show that the social dimension has the highest sustainability score (4.26; categorized as "good"), followed by governance (3.60; "fair"), environment (3.08; "moderate"), and economy (2.52; "poor"). Stakeholder mapping using the power–interest grid indicates that farmers have high interest but low influence, while agricultural offices and cooperatives have high influence. These findings form the basis for recommendations on collaborative strategies to enhance the sustainabilityof the coconut farming system.
