The Effect of Growing Media Composition and Indole–3–Butyric Acid Concentration on Growth and Flowering Time of Rose Cuttings
Full text linkThe purpose of this study is to increase the propagation success rate of Rosa centifolia L. cuttings by examining the interaction of several types of growing media with varying amounts of auxin-based plant growth regulators. A factorial Completely Randomized Design with four treatment groups and three replications. The first factor was the composition of the planting media, which was made up of four tiers of soil: soil:husk (1:1), soil:compost (1:1), and soil:manure (1:1). The second factor was the concentration of indole-3-butyric acid (IBA), which has four levels: Z1 (control), Z2 (500 ppm), Z3 (1000 ppm), and Z4 (1500 ppm). The acquired data were subjected to Analysis of Variance, which was followed by a comparison using the Least Significant Difference test to identify significant treatment effects. The results showed that the soil:compost (1:1) treatment was the most effective planting media composition in terms of shoot length, number of leaves, and flowering time. Providing auxin concentrations is not effective in increasing root growth and rose plant yield through cutting propagation.

Performance and Physicochemical Quality of Quail Eggs Given Bandotan (Ageratum conyzoides L.) Leaf Extract
Full text linkThe purpose of this study was to determine the influence of bandotan (Ageratum conyzoides L.) leaf extract on the production performance and physicochemical quality of quail eggs raised in tropical settings with ambient temperatures that exceed the comfort zone. A total of 200 female quails aged 6 weeks were reared in colony cages for 30 days. They were separated into four treatments with five replications, each with ten quails. Bandotan leaf extract was administered in dosages of 0%, 0.15%, 0.30%, and 0.45% per quail daily. The parameters measured included feed intake, feed conversion, egg production, egg mass, mortality, egg physical quality, and cholesterol and malondialdehyde (MDA) levels in egg yolks. Adding bandotan leaf extract to drinking water significantly improved quail production performance (p < 0.05). A dose of 0.30% resulted in the highest feed consumption, output, and egg mass, as well as significantly lower mortality rates, indicating its effectiveness in boosting the productivity and health of laying quails. Although it did not have a significant influence on the physical quality of eggs, administration of the extract at that dose significantly reduced MDA levels, egg cholesterol levels, and boosted antioxidant activity (p < 0.05). This demonstrates that bandotan leaf extract at a dose of 0.30% is beneficial in improving the production performance and chemical quality of heat-stressed quail eggs while preserving their physical quality.

Competency and Performance of Seaweed Farmers in Bantaeng Regency, South Sulawesi
Full text linkIndonesia\u27s marine area is around 70%, so seaweed is extensively cultivated in Indonesian waters. Although seaweed cultivation is thought to be simple, farmers confront numerous challenges. Poor farmer competence leads to low production quality, low product selling price, no negotiating position, inability to maintain production capacity, and lack of competitiveness. The purpose of this study was to assess seaweed farmers\u27 production performance and competency. This study was undertaken in Bantaeng Regency, one of South Sulawesi Province\u27s seaweed production centers. The Slovin algorithm was used to determine the number of respondents, which was 125 farmers. The method was Simple Random sampling. Descriptive analysis was used to describe seaweed farmers\u27 performance and competence, whereas Kendall W Correlation analysis was used to determine the relationship between farmer attributes and seaweed farming competence. The results revealed an average dried seaweed yield of 3,390 kg per hectare. Seaweed farmers have a high level of technical competence in operating their farms, with a total score of 13,262, however managerial competence is poor, with a total score of 5,334. The association between farmer characteristics and agricultural competence demonstrates that age has a very strong relationship, as do education, farming experience, family dependents, and land area. To increase seaweed production and income, the government must develop an integrated extension program that improves farmers\u27 technical and managerial skills.

Phenols, Tannins, and Total Colonies of Phenol-Degrading Bacteria in the Natural and Cultivated Peatlands
Full text linkPhenols play an important role in inhibiting the decomposition rate of peats. This research compares the total phenols, tannins, and colonies of phenol-degrading bacteria in natural and cultivated peatlands. The work was conducted from September to December 2023 on the peatlands in Pontianak, West Kalimantan. Samples of 60 cm3 were collected from the peat surface. The samples were taken from 4 types of peats, namely natural peats covered by ferns (A), cultivated peat with raised beds (B), cultivated peat with raised beds ameliorated with lime and beef manure (C), and cultivated peat with raised beds ameliorated with lime, beef manure, and Jadam fertilizer (D). The total phenols content was measured using the Folin-Ciocalteu 10% method using a UV-Vis spectrophotometer at a wavelength of 765 nm. The total tannins content was measured using the Folin-Denis method using a UV-Vis spectrophotometer at a wavelength of 740 nm. Total bacterial colonies were counted using the Total Plate Count method on selective Mineral Salt Medium (MSM) agar with the addition of phenol solution. The results showed that the average total phenols and tannins content values were generally low in the cultivated peats, particularly in the raised bed (B). The results indicate that the cultivated peat accelerates the activity of phenol-degrading bacteria.

Sprout Test of Seven Types of Sumatran and Javan Rice with the Addition of Liquid Organic Fertilizer
Full text linkRice productivity in Indonesia has declined due to a decrease in land area between 2018 and 2019. Another issue with rice seed dormancy is a reduction in productivity. Liquid organic fertilizer (LOF) is one way to overcome seed dormancy. The purpose of this study is to investigate the effect of soaking rice seeds in LOF on germination (viability), normal vigor of growing seeds (vigor), and germination rate. This study took place in the greenhouse and laboratory of the Department of Silviculture, Faculty of Forestry and Environment, IPB, from September to October 2022. Immersion procedures, planting, and data analysis were all steps in monitoring rice germination studies on four types of West Sumatra rice, one variety of West Java rice, and two varieties of rice from the Sukamandi Rice Research Centre. Soaking rice seeds in LOF affects their germination capacity and rate. Pandan Wangi had the maximum germination capacity and average seed count on filter paper medium, while Inpara 8 had the highest germination capacity and average seed count on vermicompost media with a 1:3 immersion. Anak Daro and Cikawasen had the fastest germination rates on filter paper media, whereas Pandan Wangi did the best on vermicompost media.

Effect of Ammonium Sulfate on Flower and Pod Development of Soybean [Glycine max (L.) Merr.]
Full text linkSoybean [Glycine max (L.) Merr.] is a food crop rich in vegetable oil and protein, with increasing demand and economic worth. Increasing soybean production can be accomplished by providing nutrients nitrogen and sulfur, hence increasing the percentage of bloom development into pods. Applying ammonium sulfate at the start of planting can fulfill nitrogen and sulfur fertilizer requirements. The purpose of this study was to examine and determine the ideal concentration of ammonium sulfate for optimal flower and pod formation, as well as the percentage of flower development into pods and leaf sulfur content. Ammonium sulfate was applied in an experimental garden by mixing it into the planting material in polybags under controlled settings. This study employed a single-factor fully randomized design with four doses of ammonium sulfate. The treatments were ammonium sulfate [NH4)2SO4] at various concentrations of 0, 100, 200, and 300 kg/ha administered at the start of planting, with five replications. The research factors were the quantity of flowers, pods, percentage of flower development into pods, and sulfur level in the leaves. The sulfur content of the leaves was determined using an atomic absorption spectrophotometer. Data were analyzed using ANOVA at a significance level of 5%, followed by DMRT if the results were significant. The results revealed that ammonium sulfate 300 kg/ha produced the highest number of flowers, pods, percentage of flower development into pods, and sulfur content in leaves.

Proximate Characteristics and Antioxidant Activity of Polyherbal Extract in Yogurt
Full text linkFermented dairy products, such as yogurt, are well known for their health advantages. Enhancing their functional value using polyherbal mixtures constitutes a big step forward in functional food development. This study looks at the proximate composition (fat, protein, moisture, and ash content) and antioxidant activity of polyherbal yogurt enriched with green tea, cinnamon, and fenugreek seed extracts. Formulations were created with varied amounts of polyherbal extract at 0% (P0), 1% (P1), 2% (P2), and 3% (P3), with Lactobacillus bulgaricus and Streptococcus thermophilus as starter cultures (Lactina Ltd). A completely randomized design with three replications was used, and the data were analyzed using ANOVA at a 95% confidence level. The results showed substantial variations in fat (2.84−3.62%) and moisture (88.17−8.83%) content between treatments. Protein (3.92−5.03%) and ash level (0.76−0.77%) met the Indonesian National Standard (SNI) for yogurt. Polyherbal yogurt demonstrated considerably higher antioxidant activity and capacity than the control. The control yogurt (P0) had a poor antioxidant capacity of 60.81±10.89%, while polyherbal yogurt (P1, P2, and P3) had a high antioxidant capacity ranging from 252.40±11.20% to 267.44±1.44%. These findings indicate that including polyherbal extracts into yogurt not only ensures compliance with national nutritional standards (SNI), but also considerably increases antioxidant potential. Thus, polyherbal yogurt is an appealing prospect for development as a beneficial dairy product.
