Abstract

This study aims to determine the effect of peptide application with NPK fertilizer dosage on the growth and yield of onion plants (Allium ascalonium L. var. Bima Brebes). The research was carried out in February – May 2025, which is located at the green house of the Faculty of Agriculture, Science and Technology, Warmadewa University, East Denpasar District, Denpasar City with an altitude of 40 meters above sea level. The design used in this study is a Group Random Design (RAK) with 2 factors arranged factorarily. The first factor of peptide (P) consists of 3 levels of concentration, namely P0 (0 ml 111), P1 (2 ml 1-1) and P2 (4 ml 1-1). The second factor is NPK fertilizer (N) which consists of 4 dose levels, namely N0 (0 kg ha-1), N1 (100 kg ha-1), N2 (200 kg ha-1), N3 (300 kg ha-1). Thus, there are 12 combination treatments that are repeated 3 times, so that 36 polybags are needed. From the results of the study, it was found that the interaction between peptides and NPK fertilizers had a real effect on almost all the variables observed except for the variables of the number of seedlings, the number of tubers and the dry weight of the tuber oven per clump had an unreal effect. The highest fresh weight of tubers per clump was obtained at the interaction between the treatment of 4 ml 1-1 peptide and the treatment of 200 kg ha-1 (P2N2) NPK fertilizer dose which was 20.63 g, an increase of 98.37% when compared to the treatment without peptide and without NPK (P0N0) dose of 10.40 g.

Abstract

Decline in Arabica coffee productivity in the Kintamani highlands indicates agronomic constraints affecting the plant's reproductive phase. Pruning and the application of growth regulators are two essential approaches to improving the physiological balance that supports flower and fruit formation. This study aims to assess the effectiveness of pruning and Atonik application in promoting shoot, leaf, flower, and fruit-bud growth in Arabica coffee plants. The study was conducted over 12 weeks using a factorial design with a combination of pruning treatments and several Atonik dosage levels. Data were analysed using ANOVA and follow-up tests to determine the differences between treatments. The results showed that pruning consistently increased shoot regeneration and improved canopy structure, thereby optimising light capture efficiency and photosynthetic product distribution. The Atonik application strengthened the plants' physiological response by increasing meristem activity and nutrient absorption. The combination of both treatments produced the highest number of flowers and fruit buds compared to either treatment alone. Scientifically, these findings indicate that the enhancement of the generative phase is highly dependent on vegetative conditions, which are strengthened by canopy management and hormonal stimulation. This study makes an essential contribution to the development of coffee cultivation strategies that integrate pruning practices and hormone regulation to sustainably increase productivity.

Abstract

Microgreens are young vegetable seedlings valued for their high nutritional content and rapid growth cycle. Pakcoy microgreens (Brassica rapa chinensis L.) have strong potential for sustainable urban agriculture. This study aimed to evaluate the effects of different eco-enzyme concentrations and growing media on the growth performance of pakcoy microgreens. The experiment was conducted using a factorial completely randomized design with two factors: eco-enzyme concentration and growing media type. Several growth parameters were observed, including plant height, number of leaves, fresh weight, and overall growth vigor. The results showed that both eco-enzyme concentration and growing media not  significantly influenced the growth of pakcoy microgreens. Higher eco-enzyme concentrations generally promoted better vegetative growth, particularly when combined with suitable growing media. The interaction between eco-enzyme application and growing media played an important role in optimizing microgreen growth performance. These findings indicate that eco-enzyme can be utilized as an environmentally friendly input to enhance pakcoy microgreen production. The use of appropriate growing media further improves growth outcomes, supporting sustainable and efficient microgreen cultivation systems. This study provides practical insights for small-scale growers and urban farmers seeking to improve microgreen productivity using eco-friendly alternatives.

Abstract

Stunting remains a major public health problem in Indonesia and is closely associated with chronic protein deficiency in children. The development of affordable, nutrient-dense food products is therefore essential to support stunting prevention programs. This study aimed to develop protein-enriched dried noodles using Black Soldier Fly Larvae (BSFL) flour as an alternative functional food ingredient and to evaluate their sensory and proximate characteristics. Dried noodles were formulated with three different substitution ratios of BSFL flour to wheat flour, namely 50:50, 60:40, and 40:60. Sensory evaluation was conducted using a hedonic test involving 20 semi-trained panelists to assess color, aroma, texture, taste, and overall acceptability. The formulation with the highest sensory acceptance was further subjected to proximate analysis, including protein, moisture, and ash content. The results indicated that the formulation 50:50 achieved the highest overall acceptability score and was categorized as “liked” by panelists. Proximate analysis of the selected formulation showed a protein content of 23.3%, moisture content of 12.9%, and ash content of 5.3%. The moisture content met the Indonesian National Standard (SNI 8217:2015) requirement for dried noodles, indicating good product stability. The incorporation of BSFL flour significantly increased the protein content of dried noodles compared to conventional wheat-based products while maintaining acceptable sensory quality. In addition, the use of insect-based protein supports sustainable food production by utilizing environmentally friendly resources. Overall, BSFL-enriched dried noodles demonstrate strong potential as a high-protein functional food product that can contribute to improving dietary protein intake and supporting stunting reduction efforts in Indonesia.

Abstract

Gonda vegetable (Sphenoclea zeylanica) is a functional food rich in phenolic compounds, flavonoids, tannin, and vitamin C, which contribute to its antioxidant activity. Fresh gonda has a relatively short shelf life therefore, dried gonda products are developed to improve practicality, extend shelf life, and preserve bioactive components. This study employed a Completely Randomized Design (CRD) with a single treatment factor (pre-treatment) consisting of two levels, namely blanching and unblanching. The drying process was carried out using the freeze-drying method. Each treatment was replicated three times, resulting in a total of 6 experimental units. The data were statistically analyzed using an independent two-sample t-test to determine differences conducted to compare the findings with those of previous studies. The results indicated that the blanching pre-treatment combined with the freeze-drying produced the most favorable functional characteristics of dried gonda. These included a moisture content of 13.64%, yield of 16.11%, rehydration capacity of 116.36%, flavonoid content of 0.066 mg QE/g, tannin content of 0.57 mg TAE/g, vitamin C content of 0.19 mg AAE/g, and antioxidant activity of 66,43%. Color analysis showed L and a* values of 23.65 and -29.21, respectively. Sensory evaluation revealed that the color of dried gonda was rated as bright with a scoring value of 3.00 and was well accepted, with hedonic score of 4.47. The texture received a scoring value of 2.00 (slightly soft) and a hedonic score of 3.00 (neutral), while the overall acceptability reached 3.60 indicating a favorable level of consumer acceptance.

Abstract

This literature review explores the use of recycled polyethylene terephthalate (rPET) bottles to implement effective packaging principles in the bottled drinking water industry. Using a narrative review of scientific literature, industry reports, and case studies, the study highlights that rPET reduces greenhouse gas emissions, energy consumption, and reliance on fossil resources while promoting circular economy practices through bottle-to-bottle recycling. Properly processed rPET retains sufficient mechanical, thermal, and barrier properties for beverage packaging and meets food safety standards. Key challenges include material degradation, quality variability, and consumer perception, which require technological innovation and efficient waste management. Industrial examples, such as PMKN in Indonesia, demonstrate successful rPET integration, label-free designs, and compliance with safety regulations. Overall, rPET adoption illustrates a balance of technical performance, environmental sustainability, and economic feasibility in effective packaging.

Abstract

The issue of weed competition becomes increasingly critical in sweet corn cultivation when weeds are not controlled during the early stages of crop growth. This study aimed to determine the appropriate application rate of bamboo leaf litter mulch for effective weed suppression while simultaneously enhancing the growth and yield of sweet corn. The experiment was conducted within the experimental area of the Faculty of Agriculture, Universitas Gunung Leuser, Kutacane, Aceh Province, Indonesia. The experiment was arranged using a non-factorial Randomized Complete Block Design (RCBD) consisting of three treatment and three replications. The treatments were defined as D0=0, D1=2, D2=4 kg m?¹ of bamboo leaf litter mulch, which correspond to 0, 20, 40 t ha?¹, respectively. The observed variables included weed control percentage, weed cover, number of weed species, weed population density, and fresh weed biomass. Crop growth parameters were also recorded, including plant height, stem circumference, and number of leaves at 10, 20, 30, and 40 DAP. Yield-related parameters consisted of ear diameter, ear length, ear weight, kernel weight, and dry shelled grain yield. Application of bamboo leaf litter mulch at 20 t ha?¹ effectively enhanced weed control percentage at 10 and 20 DAP, while reducing weed cover percentage at 10, 20, and 30 DAP, as well as decreasing weed fresh weight at 20 DAP. Furthermore, this treatment promoted sweet corn growth by increasing plant height at 20 and 40 DAP, leaf number at 30 DAP, and improving cob length, cob weight, and grain yield of sweet corn.

Abstract

Abstract Tomatoes are a versatile crop that can be consumed fresh or used in the pharmaceutical, cosmetic, and food processing industries. Their vitamin and mineral content is beneficial to health. Organic fertilizers, derived from the decomposition of natural materials such as plant residues and animal manure, can improve soil fertility—particularly in slightly acidic soils—by enhancing soil structure and microbial activity. Tomato plants require large amounts of the nutrients N, P, and K. This study was conducted at the Faculty of Agriculture, University of Papua, Manokwari, from January to March 2026. Research Design: The research was designed using a randomized block design (RBD) with a factorial pattern consisting of two factors. The factors in this study are: The factors in this study are: the compost dose treatment factor (C), which consists of 3 levels, namely: C0: Control, C1: 0.2 ml/L, C2: 0.4 ml/L, The NPK (N) dosage factor consists of 3 levels, namely: N0: Control C1: 0.2 ml/L, C2: 0.4 ml/L, The NPK (N) dosage factor consists of 3 levels, namely: N0: Control, N1: 0.2 ml/L, N2: 0.4 ml/L. This study employed a factorial randomized block design (RBD) comprising 9 treatment combinations, each with 3 replicates, resulting in a total of 27 experimental units. Data were analyzed using Analysis of Variance (ANOVA) and yielded significantly different results, followed by a 5% BNJ analysis. The observed variables included plant height (cm), number of leaves, stem diameter (cm), number of fruits, and fruit weight. Based on these results, it can be concluded that the application of compost hormones had no effect on any of the observed variables. The application of gibberellin hormones had a significant effect on fruit diameter, number of fruits, and fruit weight per plant but had no significant effect on plant height and number of leaves

Abstract

Microplastic pollution has become a serious concern at the local and global levels, due to its harmful impact on the environment and living beings. This problem has also attracted attention among Indonesian researchers and has become the topic of extensive study and scientific research. A bibliometric approach has been conducted to map 328 published articles related to microplastics research in Indonesia from the Scopus database during 2010-2023, in terms of annual publication growth, research hotspots, etc. This study also presented the inventory of microplastic abundance in various terrestrial and aquatic environments in Indonesia, as a warning of how polluted our environment is by microplastics, so that it can receive greater attention. In Indonesia, research related to microplastics began to receive attention in 2016, and the year 2019 marked a higher interest in this topic. This study also revealed that microplastics studies in Indonesia mainly focused on (1) studies related to microplastics contamination (abundance, distribution, type of microplastics, etc.) in various aquatic and terrestrial ecosystems, (2) impact of microplastics on plant, animal, and human health, and (3) biodegradation of microplastics. The last topic is less studied than the other two, opening up opportunities for more intensive studies in the future. This is because Indonesia is one of the mega-biodiversity countries, which holds potential indigenous microbes and meso-fauna for microplastic degradation.
