Plant health is a very important factor in the agriculture system. The presence of plant hormones such as Auxin, gibberellic acid, and siderophores with variation numbers in the plant gives different effects on plant health. Related to the environment rich with rhizobacteria, they have a unique function because rhizobacteria can produce a chemical compound known as Plant Growth Promoting Rhizobacteria (PGPR). The purpose of the research is to study the production of auxin, gibberellic acid, and siderophore from rice rhizobacteria as the source of potential hormones for plant growth. Ten rhizobacteria isolates have been isolated from the rice rhizosphere. They are potential candidates as biofertilizers and biopesticide agents. The hormone production from each isolate was tested by spectrophotometric methods: Auxin at a wavelength of 535 nm with Salkowski's reagent, gibberellic acid at 254 nm, and siderophores at 560 nm with Hardaway's reagent. The results showed the highest auxin hormone was obtained from isolate 10 (3.374 ppm), the highest gibberellic acid from isolate 4 (3.960 ppm), and the highest siderophores hormone from isolate 2 (2.910 ppm). The conclusion of the research is, plant growth regulator from rice rhizobacteria has the potential increasing plant health.

Rice is one of the food crops and commercial crops. Rice also has the potential to contribute significantly to increasing income and employment in rural areas. As indicated by rice imports from Thailand and Vietnam, national rice production has not been able to meet domestic demand. The objectives of this study were (1) to determine the actual and potential land suitability levels of rice plants in Luwu Regency and (2) to find out the limiting factors for actual and potential land suitability of rice plants in Luwu Regency. Evaluation of rice land suitability using the FAO method. Based on the limiting factors of land characteristics. The results showed that the actual land suitability of plants was marginal (S3fn) with the limiting factors for nutrient retention (organic C) and available nutrients (P2O5 and K2O). Efforts to improve the limiting factor can be made by adding 59.6 t organic matter ha-1, 332.6 kg P2O5 ha-1, and 98 kg K2O     ha-1 so that the actual land suitability of marginal (S3) becomes very suitable (S1).

Corn is one type of food crop known by many people because corn is one of the staple food ingredients with a variety of processed foods. In addition, corn can also be used as animal feed. There are many factors that affect the sustainability of corn cultivation.  The purpose of this study were: (1) analyzing the sustainability of corn cultivation in Herlang of Bulukumba district; (2) analyzing the sensitive attributes to the sustainability of corn cultivation in Herlang of Bulukumba district. Based on the results of the analysis, the sustainability index value of corn cultivation were: ecological dimension 61.10%, social and cultural dimension 53.73% with a quite sustainable category, while the economic dimension is 40.15%. infrastructure and technology dimensions 44.12% and legal and institutional 44.59% with less sustainable categories. The results of the analysis of leverage 51 attributes, there are 17 sensitive attributes that affect the sustainability of corn in Herlang district, Bulukumba regency. Improvement of attributes, especially sensitive attributes, can improve corn sustainability index.

This article examines the role of Al-Baqiyatush Shalihat Tanjung Jabung Barat—Islamic Jambi's (Boarding School) Pesantren in promoting tolerance and deterring radicalism. When the surrounding environment is so plural with many religions other than Islam, this pesantren remains true to the principles of tolerance and is not fanatical. When the region around the pesantren drew public attention as a hotbed of radicalism and terrorism, the pesantren continued to instill kindness, anti-radicalism, and anti-terrorism. In the fight against radicalism and terrorism, this pesantren collaborates with the local government. In this article, the major question is how the pesantren strategy instills tolerance values in efforts to deradicalize or counter-terrorism acts. The research relied heavily on observation, which was supplemented by interviews with Kyai and Ustadz, students, and neighbors in the vicinity of the pesantren. The Pesantren Al-Baqiyatush Shalihat, according to this study, has the natural ability to oppose radicalism through the use of the Pesantren Al-Baqiyatush Shalihat.
