Soil microorganisms have an important role in improving soil health and supporting sustainable organic agriculture. They contribute to the decomposition of organic matter, management of nutrient cycles, control of pathogens, and improvement of soil structure. This research explores the role of microorganisms, such as bacteria, mycorrhizal fungi, and actinobacteria, in supporting soil fertility by increasing the availability of nitrogen, phosphorus, and potassium for plants, as well as improving soil quality by increasing water retention capacity and reducing erosion. These microorganisms also act as biocontrol agents that inhibit pathogens, thereby reducing the need for chemical pesticides. However, managing soil microorganisms faces major challenges due to environmentally unfriendly agricultural practices, such as the use of pesticides and chemical fertilizers. This research emphasizes the importance of implementing sustainable agricultural principles to conserve soil microorganisms and maintain the health of the soil ecosystem as a whole. This study aims to provide insight into the role of soil microorganisms in increasing organic agricultural yields and recommend more effective and environmentally friendly management. These findings are expected to support the development of more productive and sustainable organic agriculture.
 

Chili (Capsicum annuum L.) is a high-value horticultural commodity, but its productivity is often hampered by factors such as soil conditions, climate, pests and disease. The use of plastic mulch, especially the black-silver type, can increase chili yields by 25–40% through weed control, maintaining soil temperature, and reducing evaporation. Although initial costs are relatively high, significant yield increases can offset those costs. However, the resulting plastic waste is an environmental problem, so biodegradable mulch can be a more environmentally friendly alternative. This research uses a literature review method to collect and evaluate information from various relevant sources regarding the application of plastic mulch in increasing chili productivity. With proper management, plastic mulch can support increased chili yields and agricultural sustainability.

This study examines the main pests and diseases that attack cayenne pepper (Capsicum frutescens) plants grown in polybags. In Indonesia, this crop is in high demand for both household and industrial use. Nonetheless, farmers often face challenges from pest and disease attacks, including anthracnose, fusarium wilt and stem rot, leading to reduced yields. The methodology used was a literature review covering various sources related to cayenne pepper. Findings show that important diseases such as anthracnose can reduce yields by up to 80%, while pests such as fruit flies can cause chili fruits to drop prematurely before harvest. Effective pest and disease management is essential to increase the productivity of cayenne pepper cultivated in polybags.

The rapid advancement of information and communication technology has transformed and opened business perspectives and operations, particularly in UMKM the photography industry. As the demand for online photography services continues to rise, it is crucial for service providers to develop efficient information systems to manage photo sales effectively. The research titled "Development of the POVSHOT Mobile Application for Online Photo Sales Using Flutter and MySQL" aims to facilitate online photo sales through the implementation of Flutter technology and a MySQL database. The findings indicate that the "POVSHOT" application successfully integrates features such as photo uploading, payment management, and user administration within a user-friendly interface. This study suggests that the use of mobile applications can enhance security in the photo sales process and provide a better experience for users. The implications of this research highlight that photography service providers can leverage mobile technology to expand their market reach and improve customer satisfaction through a more integrated and responsive system.

Chronic kidney failure in the end stage requires kidney replacement therapy in the form of haemodialysis. Haemodialysis is not to cure but as a replacement therapy for kidney function to clean the blood from various substances that cannot be excreted naturally by the kidneys which must be done for life. Chronic kidney failure patients undergoing haemodialysis can cause life changes that will affect the patient’s quality of life. This study aims to determine the relationship between the duration of haemodialysis therapy and age and the quality of life in chronic kidney failure patients at PKU Muhammadiyah Gamping Hospital. This study employed a descriptive correlation study with a cross-sectional method. The study population was 165 patients with a sample of 115 respondents. The instrument to determine the quality of life was the Kidney Disease Quality of Life (KDQOL) Questionnaire and interviews were done to determine the age and duration of haemodialysis therapy. The results of statistical tests using the Kendall Tau test showed a p-value> 0.05, which is 0.059 for the test of the duration of haemodialysis therapy with quality of life. Thus, it can be concluded that there is no significant relationship between the duration of haemodialysis therapy and quality of life in chronic kidney failure patients at PKU Muhammadiyah Gamping Hospital. Statistical tests for age with quality of life using the Kendall Tau test showed a p-value> 0.05, which is 0.694. Therefore, it can be concluded that there is no significant relationship between age and quality of life in chronic kidney failure patients at PKU Muhammadiyah Gamping Hospital.

This research aims to analyze the role of Customer Relationship Management (CRM) implementation in increasing customer loyalty in the digital era. With the rapid advancement of technology, CRM has become an essential component of an effective digital marketing strategy. This research uses a qualitative descriptive method with a case study approach involving several companies that use CRM as a strategy to maintain and increase customer loyalty.

Using organic fertilizer can increase soil fertility, which is crucial for plant growth. Another organic material source that may be utilized as fertilizer is water hyacinth (Eichhornia crassipes). The chemical makeup of water hyacinth was examined in this study, and the results indicated that its organic matter content was 78.47%, its organic carbon content was 21.23%, its total nitrogen content was 0.28%, its total phosphorus content was 0.0011%, and its total potassium content was 0.016%. It has been demonstrated that applying water hyacinth-based liquid organic fertilizer to corn (Zea mays) plants actually affects crop output. Utilizing water hyacinth not only improves soil fertility but also lessens pollutants in the environment caused by overgrowth in waterways. Water hyacinth can therefore be utilized as a sustainable and eco-friendly organic fertilizer option.
