Authors: Zahra A M , Sinaga A N K , Nugroho B D A , Masithoh R E 
Published: February 2024

Abstract
By controlling environmental conditions, indoor farming can increase plant growth, productivity, and harvest quality. An additional element that can enhance lettuce yield is the utilization of plant biostimulants. These substances can boost nutrient absorption efficiency, enhance resistance to environmental stresses, and foster positive impacts on plant growth and maturation. This study examined the impact of red and green romaine lettuce with different plant biostimulants (Viva®, Megafol®, Radifarm®) added to AB mix on lettuce growth under white LED lighting on 30 days of cultivation. The MANOVA tests showed that different varieties of romaine lettuce and plant biostimulants substantially affected chlorophyll b, total chlorophyll, leaf number, leaf area, leaf weight, and root weight. A polynomial growth model was also obtained from height data collected during 30 days of planting, with an optimal R2, RMSE, MAE, and MAPE reaching the optimal value of 0.9926; 0.50; 0.46; 1.72, respectively, for red lettuce with Viva®, and 0.9930; 0.11; 0.29; 2.37, respectively, for green lettuce with Viva®. In addition, Pearson Correlation analysis between each treatment indicated a positive and substantial correlation in various growth indices, up to 0.901.

Abstract
Sorghum (Sorghum bicolor (L.) Monch) is a cereal crop that is drought tolerant and can be produced worldwide. Sorghum plants can be developed in Indonesia as animal feed. This is due to agroecological conditions that can tolerate land conditions in Indonesia. This article aims to review the potential and utilization of sorghum as a source of animal feed that can be developed on dry land. The article method uses descriptive by reviewing the results of research on sorghum. Harvest can be done at the age of 85 to 90 days because sorghum has high nutritional value and is a substitute for other feed sources, because it has a high chemical composition, vitamin, mineral, and energy content. The nutritional content of crude protein sorghum is 10,4, fat 1,5 and ash 6,8%. In fresh conditions, the leaves and stems of sorghum do not last long, so it needs processing in the form of silage to extend its shelf life so that it can be used in the dry season. Giving feed derived from leaves, straw, by-products of sorghum shows a positive response in livestock. This study concludes that orgum has the potential to be developed as a source of animal feed because it has a fairly good nutritional content and has the potential to be developed on dry land.

The impact of biological asset disclosures and economic sustainability on firm value: Evidence from agricultural companies in Indonesia
Authors: Ika S R , Farida F N , Asih S N , Okfitasari A , Widagdo A K 
Published: February 2024

Abstract
This research aims to investigate whether biological asset reporting and the economic sustainability of the firm affect its value. In accordance with the Indonesian Statement of Financial Accounting Standard 69 (PSAK 69), corporations are required to disclose their methods of recognizing and valuing the fair market value of assets pertaining to living things such as plants or animals. Hence, whether biological asset disclosure impacts investors’ decisions to value the firm is the focus of the study. The study also examines if PSAK 69 increased agricultural corporations’ biological asset disclosure. The comparison test shows that PSAK 69 increased the disclosure. The Altman Z-rating probability of bankruptcy is a proxy for economic sustainability. Utilizing 56 listed agricultural firms from 2017 to 2020 as a sample, the regression analysis reveals that biological asset disclosure does not influence firm value. Instead, economic sustainability and other financial indicators such as profitability and the level of debt affect the value of the firm. The results imply that the agricultural corporation’s reputation in the eyes of shareholders is dependent upon its economic sustainability instead of the dissemination of information on its biological assets. The research provides insight into the non-value relevance of biological asset reporting in the context of Indonesia.

Authors: Astuti E N J , Nugroho D A , Ahmadi T P , Pamungkas A P 
Published: February 2024

Abstract
The bacterial cellulose (BC) fermentation is affected by environmental growth conditions such as pH, temperature, and turbidity. During the fermentation, a real-time image processing method was applied to observe the BC growth by using soybean-boiled wastewater and coconut water as a mixture. Cellulose will be produced and discharged into the medium throughout the fermentation process to form BC sheets, which will gradually become visible. The purpose of this study is to investigate the correlation between the growth parameters of BC and to analyze the formation of BC kinetically, using the Gompertz model on medium without additional nitrogen source and medium with additional nitrogen sources during the fermentation process. The strongest correlation result was found between time and thickness of BC formed without an additional nitrogen source, and with sodium glutamate as the nitrogen source. The Gompertz model equation was suitable for predicting the kinetics of BC formation time and thickness based on the available data. Both mediums exhibited three clusters that represented the adaptation stage, the exponential stage, and the stationary stage during the fermentation process. The addition of a nitrogen source to the medium resulted in thicker BC sheets compared to the medium without this addition.
