Abstract

The high demand for sand as a material is in line with the increase in sand mining activities. The main sand mining location commonly takes place in rivers. Even though rivers are also used as the main source for agricultural irrigation.  The sand mining activities could affect river water quality, which could also impact irrigation on plant growth and crop yields. This review aimed to analyze the impact of sand mining in several locations in Indonesia on river water quality for irrigation. The data collection method was carried out by searching for articles according to the topic on Google Scholar using several predetermined keywords. Analysis and review were carried out through several stages and 6 articles were obtained according to the topic. Sand mining activities in rivers are frequently carried out using manual and mechanical techniques. The use of manual techniques in mining can have an impact on river morphology as well as the physical and chemical quality of river water. Mechanical techniques have a greater impact on changes in river water quality, where most mining is carried out using manual techniques. Therefore, the sand mining with mechanical techniques, especially using excavators, can have a higher impact on the quality of river water for irrigation.

Abstract

Application of fertilizers and mulches can potentially improve crop productivity. However, the effectiveness and sustainability of these inputs depend on how they are managed. The objective of this study is to evaluate the effects of organic and chemical fertilizers, and plastic and bamboo leaf mulches, on the physiological growth and productivity of curly chili (Capsicum annuum L.). Experiment was performed according to a randomized block design with two factors. First factor was fertilizer (P) types consisting of three levels, namely: P0 (no fertilizer), P1 (ecoenzyme organic fertilizer), and P2 (NPK fertilizer). The second factor is the type of mulch (M) consisted of three levels, including M0 (without mulch), M1 (bamboo leaf mulch), and M2 (plastic mulch). Independent parameters included plant height, leaf number, and fruit weight. Results showed that fertilizer type had no significant effect, while plastic mulch significantly improved all parameters. No interaction was observed. These results suggest that plastic mulch effectively enhances chili growth and yield, particularly in the vegetative stage, but its long-term effects warrant further research.   Keywords: Bamboo leaf mulch, Chemical fertilizer, Curly chili, Organic fertilizer, Plastic mulch.

Abstract

Pemanfaatan biochar sebagai upaya perbaikan kondisi lahan pertanian di Indonesia dengan beragam bahan pada berbagai kondisi atau jenis tanah yang berbeda-beda telah dilakukan untuk melihat respon tanah yang dihasilkan dari keberagaman bahan biochar tersebut. Kondisi lahan yang semakin kritis dan jenis tanah yang berbeda di Indonesia menyebabkan dilakukan banyak percobaaan untuk melihat jenis atau bahan biochar yang cocok dengan jenis tanah yang berbeda tersebut. Banyak penelitian terdahulu yang menunjukkan adanya hasil atau respon beberapa jenis tanah terhadap bahan biochar yang diberikan. Namun, belum semua jenis tanah di Indonesia telah dilakukan uji coba terhadap penggunaan biochar karena beberapa sifat dan karakteristik tanah yang tidak layak untuk digunakan sebagai lahan pertanian pertanian. Artikel ini berusaha menjabarkan kembali beberapa fakta penelitian terdahulu tentang penggunaan biochar dengan beragam bahan sebagai agen perbaikan kualitas tanah untuk meningkatkan produktivitas pertanian.

Abstract

Sustainable agriculture is one of the latest innovations in the agricultural sector. This should consider the importance of environmental sustainability in its application in agriculture to prevent and minimize land damage and environmental pollution. One of the main pollution cases on agricultural land is the excessive use of chemical fertilizers to promote and maintain plant growth. Besides, providing plant nutrition can be done with the presence of ecoenzymes. Ecoenzymes are the result of complex fermentation of organic waste which can be used as plant growth and nutrient enhancers. This review study aimed to examine the effectiveness impact of providing ecoenzymes on various cultivated plants in Indonesia. Based on the results of the review, the ecoenzymes can help the growth of horticultural, ornamental, food, and annual plants which are also influenced by various characteristic factors, plant type, and concentration dose. Dosing ecoenzymes also depends on the use of additional fertilizer during the planting period.

Abstract

Nitrogen availability is a critical determinant of chili yield, and its dynamics are influenced by environmental conditions and cultivation practices such as mulching. This study aimed to evaluate the combined effects of environmental factors and mulching on soil nitrogen levels in curly chili (Capsicum annuum L.) cultivation using organic fertilizer under a sustainable agriculture framework. The experiment used a randomized block design with 24 plots and three treatments: no mulch (P1M0), organic mulch with bamboo leaves (P1M1), and inorganic mulch with plastic (P1M2). Monitoring was conducted for 4 months on soil pH, volumetric water content (VWC), electrical conductivity (EC), temperature, rainfall, solar radiation, humidity, and wind speed. Results showed that soil nitrogen was highest in no mulch (31.1 mg/kg), followed by organic mulch (28.8 mg/kg), and lowest in inorganic mulch (25.6 mg/kg). ANOVA confirmed that organic mulch was comparable to no mulch, but significantly better in maintaining nitrogen than inorganic mulch. Regression analysis identified electrical conductivity as the strongest positive predictor across all treatments, while soil pH showed negative effects and average temperature tended to reduce nitrogen under no mulch conditions. Model accuracy was strong (R²: P1M0 = 0.799, P1M1 = 0.799, P1M2 = 0.699). The use of bamboo leaves can be an alternative in maintaining soil nitrogen availability. Mulching practices adapted to environmental conditions can enhance soil fertility and support sustainable chili production.
