The availability of organic fertilizer is one of the keys to the success of the go-organic program that is scheduled by the government. Increasing the use of organic fertilizers and reducing the use of pesticide fertilizers, it is expected to increase the yield of bamboo farming in Banyuresmi Village.

Thus, it is necessary to socialize and assist the manufacture of PGPR fertilizer in Banyuresmi Village. The method of implementing this activity includes 1) the preparation stage, namely preparing a simple guide, and preparing tools and materials for the manufacture of mycorrhizal-PGPR combination. 2) the implementation stage consists of a) (Lecture/Counseling Method); b) Training for the manufacture of mycorrhizal-PGPR combinations; Discussion and question and answer; and Evaluation. This training concludes that the residents of Banyuresmi Village are greatly helped by the training in making PGPR fertilizer.

As an institution that manages social funds, transparency must be met for the Amil Zakat Institution. By measuring the zakat transparency index, the Amil Zakat Institution can find out the extent of the implementation of transparency in the organisation. Information disclosure to the public is believed to increase public confidence in paying zakat at the Amil Zakat Institution. This study aims to measure the zakat transparency index of the Amil Zakat Institution in Banten Province. The Simple Additive Weighting (SAW) method is used to calculate the transparency index of zakat institutions. The Simple Additive Weighting (SAW) method is a multiple attribute retrieval method, where the weight of each predetermined dimension is multiplied by each variable weight, then added up. The results showed that the Amil Zakat Institution in Banten Province was included in the reasonably transparent category with an index of 0.706.
