Penurunan hasil produksi dalam satu dekade terakhir telah dirasakan oleh masyarakat petani di desa Panaikang, Kecamatan Minasatene, Kabupaten Pangkep. Berbagai upaya dilakukan untuk meningkatkan hasil panen. Ketidaktahuan petani tentang permasalahan kesuburan tanah, mengakibatkan para petani tidak dapat menemukan solusi terhadap permasalahan yang dihadapi dalam memperbaiki/mengembalikan kesuburan tanah. Oleh sebab itu dibutuhkan pelatihan selidik cepat kesuburan tanah sawah untuk mengatasi permasalahan degradasi tanah di lahan sawah. Pelatihan diberikan secara langsung dengan mempraktekkan bagaimana menggunakan alat Perangkat Uji Tanah Sawah (PUTS) tanah sawah, dan dilanjutkan dengan simulasi yang dilakukan langsung oleh beberapa kelompok tani. Hasil uji kesuburan tanah dengan alat PUTS, memiliki nilai keakuratan terutama terkait pH tanah, Nitrogen, dan Posfor, yang sudah dapat dijadikan rujukan awal dalam penanganan status kesuburan tanah dan rekomendasi peningkatan kesehatan tanah. Nilai pH tanah berbanding lurus dengan kandungan hara-hara yang terdapat di dalam tanah. Perbedaan nilai uji PUTS dan uji laboratorium, disebabkan oleh adanya perlakuan yang telah diberikan oleh petani pada tanaman padi sawah berupa pemupukan sebelum pengambilan sampel tanah, sehingga memberikan hasil yang berbeda. Uji PUTS sebaiknya dilakukan sebelum penanaman padi sawah atau setelah panen, sehingga terbebas dari kesalahan pembacaan data. Pembentukan Desa Mitra menjadi keberlanjutan kegiatan sebagai wujud pendampingan petani dalam meningkatkan kesuburan tanah sawah di Desa Panaikang. Kata kunci: Tanah, petani, PUTS, desa mitra, Pangkep. ABSTRACT The farming community in Panaikang Village, Minasatene District, Pangkep Regency, has felt a decline in production yields in the last decade. Various attempts were made to increase crop yields. Farmers' ignorance of soil fertility problems resulted in farmers being unable to find solutions to the issues they faced in improving/restoring soil fertility. Therefore, training is needed to quickly investigate the fertility of paddy soil to overcome the problem of soil degradation in paddy fields. The training was given directly by practicing using the Rice Field Soil Test Tool (PUTS) for rice fields and continued with simulations carried out directly by several farmer groups. The results of soil fertility tests using the PUTS tool have accuracy values, especially regarding soil pH, Nitrogen, and Phosphorus. These can be used as an initial reference in handling soil fertility status and recommendations for improving soil health. The pH value of the soil is directly proportional to the nutrient content in the soil. The difference in PUTS test values and laboratory tests is caused by the treatment given by farmers to lowland rice plants in the form of fertilization before taking soil samples, thus providing different results. The PUTS test should be carried out before planting lowland rice or after harvest to avoid data reading errors. The formation of Partner Villages is a continuation of activities as a form of assistance to farmers in increasing the fertility of rice fields in Panaikang Village. Keywords: Soil, farmer, PUTS, partner villages, Pangkep.

The low uptake of N and P nutrients by maize plants can be caused by the low availability or levels of N and P nutrients in the soil used as the planting medium. The Alfisol soil used in the study had N-total levels of 0.15% (low) and P2O5 of 12.76 ppm (medium). The addition of phosphate solubilizing microbes, pelleted organic fertilizer, and inorganic fertilizer can increase the availability of N and P nutrients in the soil, so that plant uptake of N and P nutrients can also increase. This study aims to determine the effect of a combination of phosphate-solubilizing microbes (PSM), pelleted organic fertilizer, and inorganic fertilizer on the nutrient uptake of maize plants. This research was conducted at the Experimental Farm, Faculty of Agriculture, Hasanuddin University and plant samples were analyzed at Hasanuddin University's Soil Fertility Chemistry Laboratory, Department of Soil Science, Faculty of Agriculture. This study used a Randomised Group Design (RGD). The treatments consisted of a combination of M0 = without phosphate solubilizing microbes; M1 = addition of phosphate solubilizing microbes; B0 = without pelleted organic fertilizer; B1 = pelleted organic fertilizer dose of 5 tonnes/ha; B2 = pelleted organic fertilizer dose of 10 tonnes/ha; A0 = without inorganic fertilizer; A1 = inorganic fertilizer 50% of the recommended dose. The results showed that the M0B2A0 treatment produced plants with the highest level of N nutrient uptake, which was 633.33% higher than the M0B0A0 treatment. In comparison, the M1B2A1 treatment had plants with the highest level of P nutrient uptake, which was 933.33% higher than the M0B0A0 treatment.

Cadmium contamination of paddy soils is a global concern because Cd can accumulate in rice through nutrient absorption, posing a food safety risk. More than a quarter of the Tallo watershed area, Makassar is a rice field that is vulnerable to pollution due to industrial activities and water runoff from urban areas. This study aims to isolate and identify Cd-resistant bacteria from paddy field soils in the Tallo watershed to find potential isolates that have the potential for bioremediation. The soil samples collected were from the rhizosphere of rice fields in the Tallo watershed, which were varying distances from the Tallo Main River. Bacterial isolation used nutrient agar media, followed by Cd resistance testing using Nutrient Agar-CdCl₂ media with increasing concentrations from 10 mg L-1 to 110 mg L-1. Molecular identification was carried out on the most Cd-tolerant isolates using the 16S rRNA marker gene with primers 27F and 1492R. From the isolation, 22 isolates were obtained, with 19 isolates resistant to CdCl2 10 mg L-1; Only five isolates could continue growing at a concentration of 100 mg L-1, and only one isolate could grow up to a concentration of 110 mg L-1; the isolate was L1(4). The isolate L1(4) exhibited the best growth and was identified as Aeromonas veronii through 16S rRNA gene sequencing. These findings highlight Aeromonas veronii as a promising candidate for the bioremediation of Cd-contaminated soils in the Tallo watershed
