Abstract

Arrowroot (Maranta arundinaceae L.) is a starch–producing plant that can potentially be used as an alternative substitute for wheat flour. Additionally, arrowroot can serve as a functional food, as it is not only a source of nutrition but also provides health benefits such as improving digestion and regulating blood sugar levels. Arrowroot tubers contain high levels of carbohydrates and bioactive phenolic compounds that function as antioxidants. Currently, no data is available on the nutritional content and antioxidant activity (DPPH assay) of arrowroot tubers from various regions of Java Island. This study aimed to analyze the quality and antioxidant activity of arrowroot tubers obtained from several locations in Java. The results of the proximate analysis (moisture and ash contents) showed that the lowest moisture content was in the Banjar 1 accession (3.44%), while the highest was in the Sragen 3 accession (12.47%). The Banjar 2 accession had the highest ash content (8.94%), while the Sragen1 accession had the lowest (3.98%). The antioxidant activity was indicated by the IC50 value, which is the concentration of the sample solution required to inhibit 50% of DPPH free radicals. Antioxidant activity analysis revealed that the Malang 1 accession had the lowest IC50 value of 163.16 ppm, indicating the highest antioxidant potential.

Abstract

Spodoptera frugiperda J.E. Smith, sometimes known as armyworm, is a serious pest in maize crops. This pest affects maize plants' leaves, resulting in yield losses of up to 79.9%. Entomopathogenic fungi is one alternate method for controlling the pest. Various entomopathogenic fungus can be found in nature, one of which thrives endophytically on plants, such as Trichoderma asperellum. The purpose of this study was to obtain and evaluate T. asperellum's pathogenicity in suppressing S. frugiperda eggs. This investigation used five T. asperellum isolates (A116, PC21, S2D11, SD34, and AB2B3) obtained from diverse plant tissues. S. frugiperda larvae were treated with 2 mL of a conidia suspension containing 108 conidia/mL and sterile distilled water as a control. The observation variables comprised S. frugiperda egg mortality, first-instar larvae mortality, pupae formation percentage, and imago formation percentage. The findings indicated that the endophytic fungus T. asperellum can infect S. frugiperda eggs. The mortality rate for S. frugiperda eggs ranged from 43.27 to 78.34%. The mortality rate of first instar larvae ranged between 36.94% and 60.22%. The application of T. asperellum to S. frugiperda decreased pupae and imago production by 39.78% and 37.87%, respectively. T. asperellum SD324 is the most effective isolate for infecting S. frugiperda eggs. Keywords: endophytes fungus, entomopathogenic fungus, larvae, maize, Spodoptera frugiperda

Abstract

The Halmahera walking shark (Hemiscyllium halmahera) is a newly discovered endemic species found only in Halmahera's marine waters. Ternate Island's waters are known to provide habitat for the Halmahera walking shark species; the coastal water ecology is primarily made up of seagrass beds and reefs, which help to sustain the species' population. However, knowledge on ecological characteristics and distribution of walking sharks remains scarce. The study aimed to determine the habitat characteristics and distribution of this rare species on Ternate Island's coastal waters. This study was carried out from March to July 2024, with four stations located in the waters of Ternate Island. The data obtained included the number of walking shark sightings, water quality, seagrass bed characteristics, and coral reef conditions. The number of shark appearances varied significantly. The number of appearances was highest at Muhajirin Station and lowest at Kayu Merah Station. Seagrass beds at all four observation stations were categorized as damaged or poor, and coral reefs had begun to erode. Keywords: coral reef, habitat condition, Hemiscyllium halmahera, seagrass bed

Abstract

Kailan has strong selling power, making it an attractive commodity for farmers. Plant introduction in a breeding program is one of the attempts being made to boost commercial kailan yield in Indonesia. The purpose of this introduction was to develop new varieties with high production, good yield quality, resistance to plant pest assaults, and adaptation in a variety of situations. The study sought to assess the agronomic properties of several imported kailan genotypes when grown in tropical lowlands. This experiment was conducted from May to July 2023 in the experimental field of the Faculty of Agriculture at Universitas Muhammadiyah Jakarta, South Tangerang City. The study employed a Randomized Complete Block Design with one treatment factor, the kailan genotype, with five levels, including three introduced genotypes (KI001, KI002, and KI003) and two national varieties as comparators (Nita and Nemo). The results revealed that the introduced genotype KI003 had superior total fresh weight and marketable fresh weight features than the other introduced genotypes and all comparator varieties. The introduced genotypes KI001 and KI002 share the same agronomic features as the two comparator varieties. The study found that all introduced varieties could adapt well to lowland tropical climatic conditions, however only the introduced genotype KI003 demonstrated superior adaptation when compared to the comparator types.

Abstract

The IPB-D1 chicken is the outcome of crossbreeding native Indonesian chickens and can produce eggs high in protein, which is excellent for bioactive peptide manufacturing. Egg white hydrolysates contain bioactive peptides with antioxidant and antibacterial properties. The purpose of this work was to assess the antioxidant and antibacterial properties of bioactive peptides produced from IPB-D1 egg white hydrolyzed with trypsin. The research procedures included determining the Haugh unit (HU) value, protein content, degree of hydrolysis (DH), and antioxidant and antibacterial activity. The hydrolysate inhibited DPPH by 44.82% and had an antioxidant capacity of 23.16 mg EVC 100/g. The hydrolysate had greater inhibition zones against Gram-positive and Gram-negative bacteria than the non-hydrolyzed egg white, indicating its antibacterial action. Inhibition zone sizes ranged from 2.42 to 3.48 mm. The findings show that enzymatic hydrolysis of IPB-D1 egg white with trypsin significantly improves its antioxidant and antibacterial properties. Keywords: antibacterial, antioxidant, bioactive peptide, IPB-D1 chicken, trypsin enzyme

Abstract

Stakeholder analysis is required to determine the roles of each stakeholder in satisfying the meat supply needs of Samarinda City, East Kalimantan Province. The purpose of this study was to assess and categorize the influence and interests of stakeholders in the beef cattle supply chain. Primary data was collected via a survey method, involving questionnaires and interviews with 49 respondents representing farmers, slaughterhouses, government officials, traders, and consumers. A stakeholder analysis was carried out utilizing an influence−interest matrix. The results indicated two main groups: Farmers and traders are major stakeholders in the meat supply chain, with enormous power and interest. In contrast, the mob, which includes customers, the government, and slaughterhouses, has significantly less power and interest. Farmers, as primary producers, and traders, as mediators between customers, play critical roles in guaranteeing meat availability and quality. While the government has regulatory power, its role as a facilitator must be expanded to encourage stakeholder participation. This study provides collaborative solutions for aligning stakeholders' views and objectives with the goal of enhancing beef availability and quality in Samarinda City. Keywords: beef, influence-interest matrix, Samarinda City, stakeholders, supply chain

Abstract

The purpose of this study was to assess the physical, chemical, and sensory features of super red dragon fruit jam using a completely randomized design (CRD) with one factor and six treatments in triplicates. The treatment was CMC concentration (0%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%). Physical factors (viscosity and spreadability), chemical properties (total soluble solids, pH, and moisture content), and sensory properties (hedonic texture test) were all evaluated, using analysis of variance (ANOVA). Treatments with a significant effect (p < 0.05) were further tested using the Honest Significant Difference (HSD) test for physical and chemical characteristics, and the Tukey test for sensory characteristics (p < 0.05). CMC concentration significantly impacted (p < 0.05) viscosity, spreadability, total dissolved solids, pH, moisture content, and hedonic texture test findings. The 0.3% CMC treatment had the highest sensory score (3.48), viscosity (63.60 Pa·s), spreadability (21.37 cm), and chemical properties (total soluble solids 65.20 °Brix, pH 3.44, moisture content 31.57%). The total soluble solids and pH values in the 0.3% CMC treatment of super red dragon fruit jam met the SNI 3746-2008 requirements. This study suggests ways to increase the economic value of super red dragon fruit through jam processing, potentially reducing farmer losses and expanding the usage of CMC with other fruit varieties to diversify fruit jam products. Keywords: carboxymethyl cellulose, Fruit jam, red dragon fruit

Abstract

The 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. Keywords: bandotan, eggs, malondialdehyde, productive performance, quail
