Abstract

This research is the development of the use of Lapindo mud and mycorrhizae as a planting medium. Lapindo mud contains nutrients such as N, P, K, Na, Ca, Mg, C organic and has a high cation exchange capacity. Mycorrhizae can increase the length of plant roots and are resistant to stress and soils contaminated with heavy metals. The study was arranged using a Randomized Block Design with factorial patterns, the first factor being the planting medium (A) and the second factor was mycorrhizae (P). The first factor is Lapindo mud and cow manure; Lapindo mud and goat manure; Lapindo mud and chicken manure with a ratio of 50%: 50%, respectively. From these two factors, 9 treatment combinations were obtained, namely A1P1, A1P2, A1P3, A2P1, A2P2, A2P3, A3P1, A3P2, and A3P3. Each treatment was repeated 3 times to obtain 27 experimental units. From the study found that there is a real interaction in providing a combination of planting media and mycorrhizae on the growth and yield of mustard plants. The best treatment combination was shown in the combination treatment of planting media (Lapindo mud and cow manure) with 10 gr mycorrhizae / plants (A1P2) on all observations (plant height, number of leaves, leaf area, fresh and dry weight of plants, root length, weight, weight wet and dry weight of root of mustard plants and absorption of heavy metal content).

Abstract

This research analyzes the consumption behavior patterns of the people of Blitar Regency and City in the context of national food efficiency from an Islamic economic perspective. The aim of the research is to identify people's consumption behavior patterns, the food efficiency strategies implemented, and the obstacles faced in national food efficiency efforts. The research method used is a descriptive qualitative approach with data collection techniques in the form of in-depth interviews, observation and documentation. The research results show that the consumption patterns of Blitar people tend to shift from staple food to non-food as prosperity increases. Food efficiency efforts are carried out through increasing production at low costs and optimizing income. However, there are obstacles in the form of uneven efficiency in the production to consumption chain. This study recommends increasing public awareness to avoid wasting the implementation and concept of maslahah in consumption patterns according to Islamic teachings.

Abstract

This research presents a phenomenological inquiry aimed at deconstructing the conventional marketing paradigm and offering a deeper understanding of alternative practices. It specifically explores the anti-marketing strategy grounded in Islamic values as implemented at Warung Jendil Mbah Yamah, a traditional micro, small, and medium enterprise (MSME) located in Blitar, East Java. Employing a qualitative approach combined with a phenomenological method, the study gathered rich and nuanced data through several techniques, including in-depth interviews with nine carefully selected informants, participatory observation over an extended period, and systematic documentation studies. The thematic data analysis conducted by the researchers revealed that the warung’s anti-marketing strategy rests firmly on three interconnected pillars: (1) a strong reliance on organic word-of-mouth  communication rather than paid advertising, (2) the deliberate creation of an authentic, personal, and inclusive customer experience that builds emotional bonds with visitors, and (3) the consistent integration of Islamic ethical values into every aspect of business operations. These findings provide a meaningful theoretical contribution by synthesizing the concepts of anti-marketing and Islamic entrepreneurship into a new model of “authentic marketing,” where ethical and spiritual values serve as the strategic foundation for long-term sustainability. In practical terms, the results offer guidance for the broader development of MSMEs in Indonesia, showing that authenticity, ethical commitment, and adherence to core values can represent a stronger and more sustainable competitive advantage than conventional promotional strategies.
