“…Aktivitas biologis dari inokulan mikroba berperan dalam memobilisasi ketersediaan nutrisi sehingga meningkatkan kesuburan tanah. Selain itu penggunaan pupuk organik secara tidak langsung dapat meningkatkan aktivitas biologi dan berdampak dalam meningkatkan beberapa karakteristik dan kesuburan tanah (Winarso et al, 2021). Pupuk hayati berpotensi dalam menghambat proses denitrifikasi untuk jangka waktu yang lama sehingga status kesuburan tanah dapat terjaga (Sun et al, 2020;Fasusi et al, 2021).…”

The use of agrochemicals is still an option in terms of providing fast nutrition and increasing plant growth more efficiently to a certain extent. However, its continuous use results in a decrease in soil quality and soil fertility, which in turn causes the accumulation of heavy metal ions in plant tissues, and affects nutritional yields and food safety. The community service activities were carried out by the SBF (Soil Biodiversity and Fertility) team of the Jember University Soil Science study program in Karangrejo Village, Gumukmas District, Jember Regency. Field visits were conducted on farmers' fields to review, evaluate and discuss qualitative characteristics of soil properties. This service activity aims to increase understanding of sustainable soil fertility management and training in making liquid organic fertilizer based on a local bacterial consortium. The results of the activity showed that farmers' knowledge of the parameters of soil properties, especially pH, nutrients, and soil organic matter, was still minimal. The level of acidity (pH) of the soil determines the factors of production through the ease with which nutrients are absorbed by plants as well as the possibility of the presence of toxic elements that can interfere with plant growth. Knowledge of soil pH is needed in relation to nutrient management and liming. A deeper understanding of several parameters of soil properties, especially soil pH values, needs to be emphasized and followed up through mentoring activities. Mentoring activities as follow-up activities for farmer groups are carried out with the target output of liquid organic fertilizer products. Entrepreneurship training for farmer groups members also needs to be carried out to build an entrepreneurial spirit and added value from livestock products by farmers so that the farmer's household economy can sustainable.

“…the ability of the soil to perform the functions of productivity, environment, and soil health [12] or by looking at the soil quality index. A good soil quality index indicates a low level of soil pollution, does not experience degradation, plants thrive, and produces products that are safe for consumption [13] [14].…”

Good soil physical characteristics are of great importance to the growth of patchouli plants. This study aims to examine soil conditions analyzed by soil physics in patchouli development areas in Aceh Barat Regency because it is one of the patchouli development areas in Aceh Province. The research method used is a descriptive method, namely through field surveys and laboratory analysis. In this study, we focused on two physical characteristics of soil, namely bulk density (BD) and soil porosity. Soil samples were taken purposively at 15 patchouli planting sites in three sub-districts in Aceh Barat, namely of Woyla Barat, Woyla Induk, and Sungai Mas, each representing a monoculture, multiple cropping and mixed garden system. Each site was given five points of soil samples at a depth of 0–30 cm using sample rings. The results of the analysis showed that, in general, the bulk density (BD) of the soil is included in the weight category with BD values ranging from 1.27–1.30 Mg/m3, while the porosity of the soil is classified as rather poor to rather good with values ranging from 48.46–50.77%. From the analysis of the data obtained, it shows that the entire patchouli development area in West Aceh has relatively homogeneous soil physics characteristics from the aspect of soil physics and soil constraints are found in poor conditions. Therefore, to improve soil quality, it is necessary to add ameliorant materials, especially types of organic amendments such as compost, biochar, manure, and other supporting factors.

The objectives of experiments were to study the contribution of biochar residue, compost and urea fertilization on crop yields, soil chemical properties, and the diversity of soil surface insects in the maize crop land. The research was conducted at the University Farm Ie Seum Research Station, Aceh Besar District, Aceh Province, Indonesia. There were three treatments: biochar residue (no biochar residue and biochar residue 30-ton ha−1 or 15 kg plot−1), compost (no compost and compost 30-ton ha−1 or 15 kg plot−1), and urea fertilizer (no urea and urea 200 kg ha−1 or 100 g plot−1). The plant yield parameters were corn weight with cornhusk and no cornhusk and corn production with cornhusk and no cornhusk. The soil chemical properties included pH (H2O), total N, available P, organic C, and cation exchange capacity. Soil surface insects were identified using experimental methods, and insects were collected using a pit fall trap (trap barber). The results showed that the combination of biochar residue and compost resulted in the highest corn yields. The combination of biochar residue, compost, and urea fertilizer increased available P, but not pH (H2O), total N, organic C, and cation exchange capacity. Surface insects on the maize plant land consisting of nine genera were classified into five orders: Blatoidea, Coleoptera, Hemiptera, Hymenoptera, and Orthoptera. Genus Aphaenogaster and Camponotus dominated soil surface insects.
