Respon Pertumbuhan dan Produksi Terong Ungu Terhadap Pemberian Kotoran Hewan Sapi dan NPK 16-16-16

Media Farica Diva, Rr. Djarwatiningsih Djarwatiningsih, Felisitas Deru Dewanti — Sun, 31 May 2026 00:00:00 +0000

This study looked at how important growth and production characteristics of purple eggplant (Solanum melongena L.) were affected by cow dung and NPK 16-16-16 fertilizer, both separately and in combination. Plant height, flowering time, total number of fruits per plant, total fruit weight, fruit length, and fruit diameter were the main emphasis of the study. A factorial design was employed in the experiment, and analysis of variance was utilized to examine the results. The interaction between NPK 16-16-16 and cow dung did not significantly affect any of the characteristics that were examined, according to the results. Plant height, flowering period, fruit quantity, weight, length, and diameter were all not substantially impacted by cattle dung alone. Better responses were obtained in a number of yield components by NPK 16-16-16, although not all results were statistically significant. In general, single factors particularly NPK have a greater impact on plant growth and yield than treatment interactions.

Inventarisasi Penyakit Tanaman Hortikultura Berbasis Gejala sebagai Informasi Dasar Pengelolaan Tanaman di Kebun Percobaan Leuwikopo, Kecamatan Dramaga, Kabupaten Bogor

A plant disease inventory is an important early approach for detecting the presence of pathogens and obtaining an overview of the distribution of plant diseases in a location. This study aims to obtain preliminary information about the group of pathogens that cause diseases in horticultural plants in Leuwikopo Plantation, Dramaga District, Bogor Regency, based on field symptom observations. The research was conducted through a field survey using visual observation methods (based on disease symptoms) and documentation of disease symptoms in various horticultural crops. The initial identification of pathogens was carried out descriptively, with reference to the morphological characteristics of common symptoms observed in the field, and data were tabulated in Microsoft Excel. Observations show that disease symptoms are caused by a group of fungi, viruses, and bacteria. Based on the proportion of symptoms in the field, fungi were the most dominant group (46.15%), followed by viruses (38.46%), with the remaining cases suspected to be caused by bacteria and parasitic plants (Cuscuta sp.). The most common symptoms of the disease are sigatoka, yellowing, and leaf stripes. The information obtained from this study is expected to serve as initial data for understanding the presence and diversity of plant diseases in the Leuwikopo Plantation. In addition, the data can serve as an initial consideration in plant disease management planning and as a basis for further research.

Respons Agronomis dan Nutrisi Rumput Gama Umami terhadap Regimen Pupuk: Implikasi Sistem Pakan Ternak

Gama Umami grass (Pennisetum purpureum var. Gama Umami) is a superior forage grass that has the potential to support ruminant livestock productivity in tropical regions. The productivity and nutritional quality of this grass are greatly influenced by the fertilization strategy applied. This review article aims to synthesize empirical findings related to the agronomic and nutritional responses of Gama Umami grass to various fertilizer regimens and their implications in livestock feeding systems. This study was compiled based on an analysis of 44 scientific articles published in the last ten years and retrieved from reputable scientific databases. The review results show that inorganic fertilizers, especially nitrogen-based ones, consistently increase vegetative growth, biomass production, and crude protein content, but have the potential to cause nutrient imbalances and environmental impacts when used excessively. Organic and biological fertilizers make an important contribution to improving soil properties, microbial activity, and the sustainability of forage production systems, although yield increases tend to be more gradual. The integration of organic, inorganic, and bio fertilizers in an integrated fertilization regime has been proven to optimize the agronomic performance and nutritional quality of Gama Umami grass in a sustainable manner. These findings emphasize the importance of balanced and contextual fertilization management to improve the efficiency of tropical livestock feeding systems.

Penguatan Implementasi Indonesian Good Agricultural Practices (IndoGAP) melalui Buku Log Budidaya Padi pada Kelompok Tani di Kabupaten Ngawi

Zidan Izzun Naja, Farikhah — Sun, 31 May 2026 00:00:00 +0000

The implementation of Indonesian Good Agricultural Practices (IndoGAP) in rice farming is becoming increasingly important because it relates to product quality, traceability of cultivation processes, and opportunities to enhance the competitiveness of farmer groups. Challenges arise in the field when cultivation practices are not accompanied by proper record-keeping, making it difficult for groups to demonstrate their activity history and readiness for certification. This article aims to examine strategies for strengthening the implementation of IndoGAP through the development of a rice cultivation logbook for the Nglencong Sari III Farmers’ Group in Dempel Village, Geneng Subdistrict, Ngawi Regency. The study employed a descriptive qualitative approach using semi-structured interviews, field observations, and documentation conducted from October to December 2024. The study results indicate that the logbook, which follows the cultivation stages from planning through post-harvest and sanitation, can serve as a simple yet adequate recording tool for traceability. Its implementation tends to be more effective when started with core activities, accompanied by easy-to-understand examples of how to fill it out, driven by the group leader’s role, and reviewed periodically during group meetings. Thus, the cultivation logbook can serve as a practical instrument to strengthen the implementation of IndoGAP while organizing farm management to be more orderly, efficient, and market-oriented.

Pemetaan Fenologi Padi (Oryza sativa) Pada Skala Petak di Subak Dlod Sema Menggunakan Citra Satelit PlanetScope SuperDove

Sun, 31 May 2026 00:00:00 +0000

Monitoring rice growth stages in areas with small and irregular plots, such as the Subak system in Bali, requires remote sensing data with high spatial and temporal resolution. This study aims to analyze the spatial and temporal variations of rice phenology stages in Subak Dlod Sema using 3-meter resolution PlanetScope SuperDove imagery. The method involved multitemporal extraction of the Normalized Difference Vegetation Index (NDVI) to identify vegetative, generative, and ripening stages. Validation was conducted through field observations at 21 sample points for each growth stage. The results indicate that the NDVI temporal profile successfully depicts rice growth dynamics in detail, with a peak average value of 0.74 during the generative phase. Accuracy assessment showed robust results with an Overall Accuracy of 88.9%, a Kappa coefficient of 0.83, and a temporal Root Mean Square Error (RMSE) of 4.0 days during the ripening stage. Despite a slight overestimation in the generative phase due to canopy saturation, the use of PlanetScope proved highly effective in mitigating mixed-pixel issues at the individual plot scale. These findings underscore the potential of high-resolution satellites in supporting precision agriculture and planting pattern management within the Subak organization.

Uji Bioaktivator MOL dan EM4 dalam Fermentasi Pupuk Kandang Sapi terhadap Pertumbuhan Awal Tanaman Jahe (Zingiber officinale)

Sun, 31 May 2026 00:00:00 +0000

This study aimed to determine the effect of bioactivators, namely Local Microorganisms (MOL) and EM4, in the fermentation of cow manure on the early growth of ginger (Zingiber officinale). The research was conducted from July to September 2024 using a non-factorial Completely Randomized Design (CRD) with three treatments: cow manure without bioactivator (P1), cow manure fermented with MOL (P2), and cow manure fermented with EM4 (P3), each replicated three times. Observed parameters included plant height, number of leaves, and number of shoots. Data were analyzed using ANOVA followed by LSD test at 5%. The results showed that bioactivator application significantly affected plant height, with EM4 treatment producing the highest growth. Meanwhile, the number of leaves and shoots did not show significant differences, although descriptively EM4 tended to give higher values. These findings indicate that the use of bioactivators, particularly EM4, can enhance early growth of ginger, although its effect is not yet optimal across all parameters.
