Abstract

Urban air pollution is a growing environmental concern, particularly in rapidly developing cities where vehicular emissions contribute significantly to deteriorating air quality. This study investigates the correlation between stomatal density in jackfruit (Artocarpus heterophyllus Lamk.) leaves and air quality in Bandar Lampung, focusing on two high-traffic urban locations: Sultan Agung Street and Pangeran Emir M Noer Street. Using a quantitative approach, leaf samples were collected through purposive sampling and analyzed for stomatal density using light microscopy (400× magnification). Concurrently, air quality was measured by assessing carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM10 and PM2.5) concentrations, which were compared against National Ambient Air Quality Standards (PP No. 41 of 1999). The results indicate a positive correlation between traffic intensity and stomatal density, suggesting that jackfruit trees increase stomatal density as an adaptive response to vehicular pollution. However, while enhanced stomatal density may improve CO₂ uptake for photosynthesis, excessive stomatal opening could lead to higher pollutant absorption, necessitating stomatal closure mechanisms during peak pollution periods. The findings confirm that jackfruit trees can serve as effective bioindicators for urban air pollution monitoring, given their physiological adaptability and widespread distribution in tropical urban settings. This research underscores the potential of plant-based bioindicators in sustainable air quality assessment and urban environmental management strategies.

Abstract

This study aims to analyse organic waste compost as an effective growing medium and evaluate its effect on the growth of pakcoy (Brassica rapa var. Chinensis) plants. In this study, we focused on analysing the content of macro and micro nutrients required by pakcoy plants, such as C, N, P, K, and Ca. We used a Randomised Group Design (RAK) with two factors: growing media (sawdust, cocopeat, husk charcoal) and organic waste compost concentration. The observation parameters include the development of pakcoy plants, namely plant height, number of leaves, and stalks of pakcoy that have been planted in organic waste compost media.The results showed that organic waste compost with a mixture of sawdust and the addition of EM4 has a nutrient content that is in accordance with the Indonesian National Standard (SNI). In addition, the organic waste compost had a more significant effect on pakcoy growth. Thus, this study shows the potential of using organic waste compost as an alternative to chemical fertilisers in vegetable cultivation. These results can help improve soil fertility and yield of vegetable crops, as well as contribute to the development of sustainable agriculture that is more environmentally friendly.

Abstract

Changes in texture and sucrose content in California papaya and kepok bananas after harvest due to metabolic processes can reduce the quality of the fruit. This research investigated the changes in sucrose content and texture during the maturation process of California papayas and kepok bananas. The observed parameters included physical properties, such as texture variations and sucrose levels in the fruit. The research followed a qualitative approach. The research results are described descriptively. This study showed a change in the texture of the kepok banana and California papaya in the ripening process. Changes in the texture of kepok bananas decreased from 3.66 kg/cm on day 2 to day 12 after harvesting from 3.66 kg/cm to 0.56 kg/cm. California papayas from 3.63 to 1.36 kg/cm2. California papayas from 3.63 to 1.36 kg/cm2. The highest sucrose content in the ripening process occurred in kepok bananas and California papayas, respectively, at 0.45? Brix on day 12 and 11.38? Brix on day 10.

Abstract

riculture in Indonesia produces various types of plants such as staple foods such as rice, corn and vegetables. Vegetables that contain a lot of nutrients include chili plants. The productivity of chili plants in Indonesia is still relatively low, one of the factors is the low soil fertility due to the use of inorganic fertilizers. Therefore, alternative organic fertilizers are made from restaurant/household waste, one of which is rice waste and sediment water from catfish ponds that can be recycled. This study aims to evaluate the impact of using liquid organic fertilizer (LOF) derived from fermented rice and catfish pond sediment on the growth of curly red chili plants (Capsicum annum L.). The research utilized a completely randomized design (CRD) with a factorial model comprising two factors. The first factor was LOF made from fermented rice (Factor M), and the second was LOF from catfish pond sediment (Factor N). Each factor was tested at three treatment levels, resulting in nine treatment combinations. Each combination was replicated three times, along with three replications for a negative control, totaling 30 experimental units. Data analysis was conducted using ANOVA, followed by post-hoc testing with the Least Significant Difference (LSD) method at a 5% significance level. The findings indicated that the optimal results were achieved with the N3M3 treatment combination, which involved a dose of 300 ml of fermented rice LOF and 300 ml of catfish pond sediment LOF per liter of water. This combination yielded the best performance in terms of plant height, leaf count, fresh weight, and dry weight.

Kunjir Village, South Lampung, has great potential to be developed as a halal tourism village; however, it still faces challenges such as the low level of understanding among the community and MSME actors regarding halal certification. This community service program aims to improve both soft skills (understanding the importance of halal certification and awareness of sharia standards in halal tourism) and hard skills (technical skills in registering halal certification through the SiHalal application) of MSME actors in Kunjir Village. The program was implemented using the Asset-Based Community Development (ABCD) approach through three stages: the pre-activity stage (Discovery), the implementation stage (Dream, Design, Delivery), and the evaluation stage (Destiny). The program involved 48 participants from 14 MSMEs producing local superior products. Evaluation of the program’s effectiveness was conducted through interviews and analysis of partners’ skill achievement data. The results showed a significant increase in participants’ skills: understanding of the importance of halal certification improved from 35% to 90%, knowledge of the registration procedure increased from 25% to 85%, technical skills in using the SiHalal application improved from 10% to 75%, and 14 MSMEs successfully registered 15 products for halal certification (100%). These findings demonstrate that the development of halal tourism villages can be carried out inclusively and sustainably through strengthening the capacity of MSMEs. Kunjir Village has the potential to serve as a replication model for other villages in developing halal tourism based on community empowerment.
