Kenaikan jumlah penduduk berbanding lurus dengan peningkatan kebutuhan akan pangan, khususnya beras. Produksi beras terbesar berasal dari budidaya padi sawah. Usaha yang dapat dilakukan untuk memenuhi kebutuhan beras adalah peningkatan produksi beras. Penelitian ini untuk memastikan ketersediaan lahan sawah yang memadai dan sesuai untuk meningkatkan produksi beras. Penelitian ini bertujuan untuk menganalisis sejauh mana lahan di bagian tengah Kabupaten Subang cocok untuk pertanian padi sawah. Metode yang digunakan adalah metode pencocokan (matching) antara kualitas lahan dengan kriteria kesesuaian lahan untuk tanaman padi sawah. Satuan peta lahan yang digunakan merupakan hasil tumpang tindih antara peta jenis tanah, dan peta kelerengan. Hasil tumpang tindih peta tersebut menghasilkan 17 satuan peta lahan yang menjadi lokasi pengambilan sampel tanah. Kelas kesesuaian lahan aktual untuk budidaya padi sawah berada dalam kategori cukup sesuai (S2rfn), serta sesuai marginal (S3fn, S3rfn, S3rn), dengan berbagai faktor pembatas seperti kondisi media perakaran, retensi hara, dan ketersediaan hara.

Peatland serves as a crucial natural resource with hydrological and other environmental functions essential for all living organisms. In some regions, peat soil isn't limited to lowland areas, it is also found in highland areas. This study is a survey research aiming to examine the characteristics of the highland peatlands of Toba North Sumatera, namely in the Village of Matiti II, Humbang Hasundutan Regency, North Sumatera and lowland peatlands as control of peatlands in general in Sidomulyo Village, Bilah Hilir Subdistrict, Labuhan Batu. The study employed a survey research approach with a descriptive method to determine the differences in the characteristics of highland Toba peat soils. In each area, a representative profile was made, and the soil morphology, characteristics and classification were observed according to the 2014 soil taxonomic classification. Soil samples were taken from each layer in the soil profile for soil analysis in the laboratory. Soil analysis included bulk density, pH H₂O, pH NaF, CEC, base saturation, organic C, total N, C/N, electrical conductivity (EC) and ash content. The results showed that the difference in altitude directly affected the microclimate and the hydrologic conditions, which in turn affected the characteristics of the peat soil. In the context of the Toba highland, the main source of peat soils comes from rainfall. In contrast with the peatland of the lowlands, where the impact of tides is a significant factor, the peat of the Toba highland is affected by the surrounding hills.

Hambatan teknis yang dapat mengakibatkan produksi kacang tanah rendah melibatkan beberapa faktor, termasuk pengolahan tanah yang kurang optimal, menyebabkan drainase yang tidak baik, dan struktur tanah yang padat. Selain itu, pemeliharaan tanaman yang tidak optimal, serangan hama dan penyakit, penanaman varietas dengan produktivitas rendah, dan mutu benih yang rendah juga dapat menjadi kendala. Dalam penelitian ini, metode Rancangan Acak Kelompok (RAK) dengan dua faktor perlakuan digunakan. Parameter yang diukur mencakup Jumlah Polong Per Sampel, Bobot Polong Per Sampel, Bobot Biji Per Sampel, dan Bobot 100 Biji Kacang Tanah. Hasil penelitian menunjukkan bahwa varietas memiliki pengaruh signifikan terhadap tinggi tanaman pada 2-7 MST, jumlah cabang pada 4, 5, 6, dan 7 MST, serta parameter lain seperti jumlah polong per sampel, bobot polong per sampel, bobot biji per sampel, dan bobot 100 biji.

Deteksi Tingkat keaslian beras Ciherang dengan penggunaan Portable Near-Infrared Reflectance Spectrometer jarang dilakukan sebelumnya, Oleh karena itu, analisis diperlukan untuk memverifikasi autentisitas beras Ciherang. Penelitian ini bertujuan untuk mendeteksi keaslian beras Ciherang dan persentase tingkat keaslian beras Ciherang secara non-destruktif menggunakan Portable NIRS. Penelitian ini dianalisis dengan metode Partial Least Squares-Regression (PLS-R) dengan dua perlakuan. Perlakuan pertama melibatkan beras Ciherang murni, dan perlakuan kedua melibatkan beras Ciherang campuran dengan persentase mulai dari 1% hingga 30%, mewakili tingkat keaslian dari 57,2% hingga 99,0%. Metode yang digunakan untuk menentukan keaslian beras Ciherang melibatkan penerapan teknologi SCIO Portable Near-Infrared Reflectance Spectrometer, dengan menggunakan metode Partial Least Squares, mampu memprediksi keaslian beras Ciherang. Hasil terbaik dicapai dengan menggunakan pre-treatment deresolve, menghasilkan nilai koefisien korelasi kalibrasi sebesar 0,99, koefisien korelasi validasi sebesar 0,99. Nilai SEC dan SEP yang diperoleh adalah 0,00% hal ini menunjukkan bahwa model kalibrasi yang digunakan efektif dalam memprediksi keaslian beras Ciherang.

This study investigates the potential of Black Soldier Fly (BSF) larvae in managing organic waste through rapid decomposition and nutrient-rich compost production. The primary objective was to evaluate the efficiency of BSF larvae in waste reduction and compost quality, particularly within urban environments, and to explore their scalability in urban waste management systems. The methodology involved controlled experiments to measure bioconversion rates at varying larval densities, temperature, and moisture levels. The compost produced by BSF larvae was analyzed for key nutrients, including nitrogen, phosphorus, and potassium. The results demonstrated that BSF larvae effectively reduced organic waste by up to 86% within a few days, outperforming traditional composting methods. The compost produced was rich in essential nutrients, making it suitable for urban farming. Factors such as optimal larval density, temperature, and moisture content were crucial for maximizing decomposition efficiency and compost quality. However, the study also identified several challenges, including space constraints, public perception, and the logistical difficulties of scaling BSF larvae systems in urban areas. In conclusion, this research highlights the potential of BSF larvae as a sustainable solution for organic waste management, compost production, and urban farming. The findings contribute to the growing knowledge on sustainable waste management and urban agriculture, offering insights into integrating BSF larvae systems into existing waste management frameworks. Future research is needed to address scalability challenges and optimize the operational efficiency of BSF larvae systems in urban environments.

The community service that has been implemented in Lubang Buaya Village, Cipayung District, in 2023, aims to stimulate the use of used bottles as an innovative solution in overcoming the food crisis and strengthening local food security. This effort is in line with government initiatives to develop domestic food security and reduce dependence on food supplies from abroad. In addition, research and development related to urban farming practices using used bottles in Cipayung plays an important role in providing practical guidance to local communities to start and run urban farming practices effectively. This step is expected to help city residents produce their own food sustainably, reduce the burden of food imports, and improve community food security. Throughout the program, a continuous evaluation phase has also been conducted. This allows monitoring the long-term impact of this activity, including the improvement of the quality of life of the local community. In conclusion, this community service program has successfully improved participants' knowledge, skills, and insights related to the basic principles of hydroponic plant cultivation. It has also stimulated business development on a household scale and contributed to the improvement of the surrounding environment.
