Abstract

The supply of nutritious food through a variety of food consumption is very important in reducing stunting prevalence. Some areas of Hulu Sungai Utara (HSU) Regency are the alabio polder area with high cases of stunting children and unproductive swamp land conditions when flooded with rainwater. This service activity provides a solution in utilizing home yards as a place to cultivate local swamp vegetables that have high nutrition, namely water spinach and water mimosa. The activities carried out include planning, which is done by direct observation and coordination with related stakeholders, then educating about the importance of consuming nutritious vegetables. Training and mentoring were given to 25 residents, the majority of whom were farming mothers. Evaluation was carried out by giving a questionnaire to participants regarding the sustainability of the activity. This activity was able to increase the knowledge and skills of the community in cultivating plants in the yard. The application of semi-hydroponic cultivation techniques of typical swamp vegetables has helped the community in providing vegetables when swamp rice fields are flooded in the rainy season and cannot be planted. Evaluation results showed that 88% of participants were enthusiastic about implementing the training in their daily lives because it suited their needs.

Abstract

Land quality is a key determinant of fruit production, supporting nutrient supply, food security, and sustainable agriculture. This study evaluates potential changes to land suitability classes to improve land-use planning and spatial rearrangement, notably to support the development of cempedak cultivation in Batu Mandi and South Paringin Districts, Balangan Regency, South Kalimantan Province. The research was conducted from May to August 2025 using a matching method to link land characteristics   to suitability criteria for cempedak, and the results were presented as ArcGIS maps. Results show both districts have considerable potential for cempedak development, although current conditions fall within unsuitable (N) and marginally suitable (S3) classes. In Batu Mandi District, actual suitability is S3 covering 11,238.48 ha, and N covering 1,541.61 ha. In South Paringin District, cempedak suitability is also S3, covering 6,953.21 ha. The main limiting factors include unsuitable soil texture, low base saturation, acidic soil pH, and low nutrient availability of P₂O₅ and K₂O. Improvement efforts involving adding pelleted compost and liming with high cultivation, and fertilising with moderate cultivation of triple superphosphate and KCl potentially increase suitability from S3 to S2 or even S1. Therefore, the land has the potential to become a cempedak planting area and produce maximum productivity.

Abstract

Peningkatan luas perkebunan kelapa sawit di Indonesia dapat meningkatkan volume limbah industri. Salah satu limbah yang dihasilkan adalah decanter solid, yang dapat menurunkan kualitas lingkungan. Disisi lain, decanter solid mengandung kalium (K), sehingga dapat dimanfaatkan sebagai pembenah tanah organik. Limbah ini dapat memperbaiki  lahan sulfat masam yang memiliki permasalahan seperti rendahnya ketersediaan dan efisiensi serapan hara. Unsur seperti K tidak tersedia akibat proses oksidasi-reduksi dan relatif mudah tercuci akibat KTK yang rendah. Tujuan penelitian ini untuk mengetahui pengaruh aplikasi decanter solid terhadap fraksi K pada tanah sulfat masam dengan teknik penggenangan, serta mengetahui efektivitasnya decanter solid dalam mensubstitusi NPK anorganik. Penelitian ini menggunakan rancangan acak lengkap (RAL), dua faktor yaitu pemupukan NPK dengan kombinasi decanter solid dan perbedaan penggenangan. Parameter tanah yang dianalisis K-tersedia menggunakan ekstrak NH4OAc pH 7 (1N), K-total menggunakan ekstrak HCl 25%, dan Serapan-K. Hasil penelitian mengindikasikan bahwa dinamika K pada tanah sulfat masam lebih ditentukan oleh input bahan organik dibandingkan kondisi hidrologi semata. Penggenangan tidak secara langsung memodifikasi fraksi K, namun berperan dalam mengubah respons tanaman terhadap K yang tersedia. Aplikasi decanter solid secara konsisten meningkatkan cadangan K tanah, khususnya pada fraksi K-total, yang mencerminkan perbaikan status hara jangka menengah. Lebih lanjut, respons serapan K menunjukkan adanya efek sinergis antara tingkat substitusi decanter solid dan kondisi penggenangan, yang mengindikasikan bahwa efisiensi pemanfaatan K tidak hanya bergantung pada ketersediaannya di tanah, tetapi juga pada interaksi proses biogeokimia yang dikendalikan oleh kondisi air.
