PEMBUATAN SABUN TRANSPARAN DENGAN PENAMBAHAN KITOSAN SISIK IKAN DAN JERUK KALAMANSI
This study aimed to determine the effect of adding fish scale-derived chitosan and Calamansi (Citrus microcarpa), a local commodity widely available in Bengkulu Province, on the quality of transparent soap. The parameters analyzed included moisture content, pH, foam stability, and antimicrobial activity. The results showed that the physical characteristics of transparent soap differed mainly in color. Soap containing chitosan from tilapia scales exhibited a clear yellow color, while soap made with snapper scale chitosan showed a darker, orange-yellow hue. Chemically, both formulations met the Indonesian National Standard (SNI 3532:2016), with pH values ranging from 9.84 to 10.45, indicating safe use for the skin. The moisture content ranged from 10.5% to 11.2%, below the maximum SNI limit of 15%, suggesting good stability and a potentially longer shelf life. Foam stability exceeded 90%, demonstrating that fish scale chitosan contributed to the formation of stable foam. Antimicrobial testing revealed that soap containing tilapia scale chitosan exhibited stronger inhibition zones against Staphylococcus aureus (14.1 mm) and Escherichia coli (12.6 mm) compared to soap containing snapper scale chitosan.

PESTISIDA NABATI DAUN BABADOTAN (Ageratum conyzoides L.) DALAM MENGENDALIKAN HAMA PADA TANAMAN PAKCOY (Brassica rapa L.)
Demand for pak choi plants has continued to increase in recent years, but due to pest attacks, it has caused unstable production of pak choi plants. The main pests that attack pak choi plants are armyworms and caterpillars. One way to control pests on pak choi plants is to use organic-based biopesticide that are safer to use. One of the organic materials that can be used for organic pesticides is goat weed leaves. Goat weed is a nuisance weed that lives wild and is found in many regions in Indonesia. Goat weed plants can be used as biopesticide because goat weed plants have bioactive content that is anti-pest. The factor studied in this. research is the treatment of goat weed leaf extract with five concentration levels repeated as many as four replicates so as to get 20 units of experimental units. The results obtained from this study are pests that attack pak choi plants in this study are armyworms, tritip caterpillars, and flea beetles. Application of botanical pesticide solution of goat weed leaves has an effect on pest control in pak choi plants. The best concentration in the application of goat weed leaves solution is at a concentration of 20%, namely with a value of pest attack intensity on pak choi of 3.1%.

BIOKONVERSI LIMBAH PERTANIAN MENJADI BIOPESTISIDA RIZOBAKTERI ANTIFUNGAL
Modern agriculture faces increasing challenges from soil-borne fungal pathogens such as Fusarium oxysporum, Rhizoctonia solani, and Sclerotium rolfsii, which cause severe root and wilt diseases and significantly reduce crop productivity. This study employed a qualitative–descriptive approach supported by controlled laboratory experiments to evaluate the potential of agricultural waste as an alternative, low-cost substrate for producing antifungal rhizobacterial biopesticides. Six types of agricultural waste—rice straw, rice husk, corn cob, sugarcane bagasse, coffee husk, and soybean residue—were assessed based on their C/N ratio, lignin content, biodegradability, and nutrient availability. The results indicated that substrates with moderate C/N ratios (15–25) and low lignin content, particularly soybean residue and sugarcane bagasse, promoted optimal rhizobacterial colonization, robust biofilm formation, and high production of antifungal metabolites such as chitinase and siderophores. Rhizobacteria cultured on soybean residue exhibited the strongest inhibition zone against Fusarium oxysporum (20.5 mm) and the highest plant protection efficacy (88%), with biopesticide stability maintained for up to 120 days. Two conceptual models, Substrate Structure Colonization (SSC) and Media Metabolite Effectiveness (MME), are proposed to explain the relationship between substrate structure, metabolite biosynthesis, and biopesticide performance. These findings provide a sustainable strategy for converting agricultural waste into high-value bio-based inputs, supporting circular economy practices and green agriculture initiatives.

ADAPTASI MORFOLOGI DAN FISIOLOGIS TANAMAN PADI SAWAH TERHADAP CEKAMAN GENANGAN AIR
Rice (Oryza sativa L.) is a major staple food crop in Indonesia whose production is highly vulnerable to flooding stress as a result of climate change. This article presents a systematic–narrative literature review examining scientific publications from the past ten years concerning the morphological and physiological responses of rice plants to flooding stress. The synthesis indicates that the main adaptive mechanisms of rice include the formation of aerenchyma tissue and adventitious roots, regulation of stem elongation (escape and quiescence strategies), and activation of anaerobic metabolism regulated by the SUB1A and SNORKEL1/2 genes. These mechanisms have been reported to enhance plant survival and maintain rice yield by approximately 20–40% compared with flood-intolerant varieties. An integrated understanding of these adaptive responses has important implications for the breeding of flood-tolerant rice varieties, adaptive water management in paddy fields, and the development of cultivation strategies in flood-prone areas to maintain rice production stability and support national food security amid climate change.

APLIKASI KECERDASAN BUATAN DAN PEMAHAMAN MESIN DALAM PERTANIAN URBAN: TINJAUAN SISTEMATIS DAN PERSPEKTIF MASA DEPAN
This study aims to conduct a systematic and comprehensive literature review on the applications of artificial intelligence and machine learning in vertical farming, focusing on technology optimization, economic aspects, and environmental sustainability. The method used is a systematic literature review (SLR) of open-access academic publications from reputable international databases such as Scopus, Web of Science, and Google Scholar, with a publication timeframe spanning the last five years (2018-2023). The review results indicate that the most widely applied soilless cultivation technologies are hydroponics, aeroponics, and aquaponics, with aeroponics demonstrating the highest water use efficiency. The integration of IoT, smart sensors, and AI can increase crop productivity; however, the carbon footprint of these systems is highly dependent on the energy source used. The main barriers to adoption are high initial investment and operational energy costs. This article contributes to updating and expanding the understanding of the applications of artificial intelligence and machine learning in vertical farming, as well as identifying research gaps and proposing directions for technology and policy development oriented towards sustainability and profitability

FISIOLOGIS TANAMAN CABAI MERAH (Capsicum annuum L.) TERHADAP CEKAMAN KEKERINGAN DI LAHAN PESISIR
Red chili pepper (Capsicum annuum L.) is a major horticultural crop with high economic importance and a vital role in meeting food demands. Its demand continues to increase alongside population growth, yet production is often limited by drought stress, particularly in coastal regions characterized by sandy soils, low water-holding capacity, and high salinity. This review aims to assess the physiological responses of red chili plants to drought stress in coastal environments and to identify adaptive mechanisms that enhance plant tolerance. Drought stress has been reported to decrease photosynthetic activity, chlorophyll concentration, and transpiration rate due to stomatal closure. Plants counteract water deficit by accumulating osmolytes such as proline and soluble sugars and by enhancing antioxidant enzyme activities, including superoxide dismutase (SOD) and peroxidase (POD), to mitigate oxidative damage. Drought conditions also result in significant reductions in plant height, flower number, and fruit yield, reaching up to 51%. These adaptive mechanisms highlight the importance of developing drought-tolerant cultivars and applying water-efficient cultivation techniques, such as silver-black plastic mulch and drip irrigation, to sustain red chili productivity in drought-prone coastal regions.

PENGARUH POC LIMBAH CUCIAN BERAS TERHADAP PERTUMBUHAN DAN HASIL SAWI CAISIM (Brassica juncea L.)
This study aims to analyze the effect of Liquid Organic Fertilizer (POC) from rice washing waste on the growth of Chinese cabbage (caisim) and to determine the most optimal application dose. The study used a Randomized Block Design (RBD) with five dose levels: 0 ml (control), 150 ml, 250 ml, 350 ml, and 450 ml per plant. A total of 125 plants were observed through five replication blocks, with the focus of parameters on vegetative growth and plant biomass. Application of POC from rice washing waste significantly increased the number of leaves, leaf width, plant fresh weight, and root fresh weight, but did not have a significant effect on plant height. A dose of 250 ml/plant (P2) was identified as the most effective dose that produced the highest fresh weight, number of leaves, and leaf width. Thus, POC from rice washing at this dose has great potential as an environmentally friendly organic nutrient alternative for Chinese cabbage cultivation.

PENGARUH ZPT GA₃ DAN ZPT ALAMI KATANG-KATANG TERHADAP PERTUMBUHAN BIBIT TANAMAN MATOA (Pometia pinnata)
This study aims to evaluate the effect of the administration of Growth Regulating Substances (ZPT) gibberelin (GA₃) and natural ZPT derived fr om katang-katang plants on the growth of matoa seedlings (Pometia pinnata). The study was conducted using a factorial Completely Randomized Design (RAL) with two factors, namely GA₃ concentration (A0 = no treatment, A1 = 50 ppm, A2 = 65 ppm, and A3 = 80 ppm) and natural ZPT concentration of katang-katang (K1 = 15 ppm, K2 = 30 ppm, and K3 = 45 ppm). The observed parameters included plant height, number of leaves, leaf width at the age of 14, 28, 42, 56, 70, and 84 days after planting (HST), as well as the length and number of roots at the age of 84 HST. The results showed that GA₃ administration had a significant effect on plant height, leaf count, root length, and root count, with a concentration of 65 ppm (A2) showing the best results in most vegetative growth indicators. Meanwhile, the natural ZPT treatment of katang-katang also had a significant effect on the number of leaves and roots, where the concentration of 30 ppm (K2) resulted in the highest number of roots. The interaction between the two types of ZPT had a significant effect on the root count parameters, with the combination of GA₃ 65 ppm and 30 ppm katang-kaang providing the most optimal results. Overall, the combination of synthetic ZPT GA₃ and natural ZPT is effective in increasing the vegetative growth of matoa seedlings and has the potential to be an environmentally friendly alternative in plant propagation.

UJI EFEKTIFITAS PENAMBAHAN AIR KELAPA FERMENTASI, ASAM ASETAT, ETANOL, DAN GARAM PADA GLIFOSAT TERHADAP GULMA DI PERKEBUNAN SAWIT YANG BELUM MENGHASILKAN
Oil palm is a strategic commodity that plays a vital role in Indonesia's economy, but its productivity is often hindered by weed infestation. Chemical weed control commonly relies on synthetic herbicides, which pose environmental risks. This study aims to evaluate the effectiveness of a new natural-based herbicide formulation consisting of fermented coconut water, ethanol, acetic acid, salt, and low-dose glyphosate in immature oil palm plantations. The research employed a single-factor Randomized Complete Block Design (RCBD) with nine formulation treatments and three replications. Vegetation analysis revealed three dominant weed species in the experimental area: Borreria alata, Ageratum conyzoides, and Asystasia gangetica. The results indicated that all herbicide formulations were able to suppress weed populations and dry weight, although the differences were not statistically significant. Numerically, Formulation 8 (F8) provided the best results, achieving a weed mortality rate of up to 99%. In contrast to previous formulations requiring high application volumes (35–50 L/ha), this new formulation is more efficient at a dosage of 4–6 L/ha. This formulation works synergistically, is environmentally friendly, and has the potential to support sustainable agricultural practices
