Peanut has long been cultivated in Indonesia and is generally grown on dry land. The continuous use of inorganic fertilizers can have a negative impact on the soil, so there is a need for environmentally friendly fertilizers such as biological fertilizers. This study aimed to elucidate the effect of mycorrhiza biofertilizer on the vegetative and generative growth of peanuts. The study was conducted in the experimental field of Cikabayan IPB with a three-factor Completely Randomized Design. The treatments tested were 1) control, 2) 100% NPK fertilizer, 3) 100% organic fertilizer, 4) 100% organic fertilizer + NPK, 5) 5 g mycorrhizae, 6) 100% NPK + mycorrhizae 5 g, 7) 100% organic fertilizer + mycorrhiza 5 g, and 8) organic fertilizer + NPK 100% + mycorrhiza 5 g. Parameters observed included plant height, number of primary branches, number of pods, pod weight, colonization or root infection, number and types of spores. The results showed that the application of NPK fertilizer + organic fertilizer + mycorrhizae 5 g could increase vegetative and generative growth in peanut plants. The treatment of NPK+ organic fertilizer + mycorrhizae 5 g (AOM) had a very high percentage of infection, which was 86.67%. The AOM treatment had a high number of spores, which was 32 spores and 3 types of spores were successfully associated, namely Acaulospora sp1, Acaulospora sp 2 and Glomus etunicatum.

Gold mining is closely related to land degradation caused by heavy metals such as lead (Pb), which are non-degradable, non-essential, and immobile. This study aims to compare soil lead levels before and after phytoremediation using local plants. Plant species consist of white teak (Gmelina arborea Roxb.) Pulai (Alstonia scholaris L.R.Br.), ganitri (Elaeocarpus ganitrus Roxb.), pine (Pinus merkusii Jungh), rasamala (Altingia excelsa N.) and puspa (Schima wallichii K.) with the planting position on the upper terrace, middle terrace and lower terrace. Soil characteristics observed were texture, spH, and lead content. The two-sample pair test (paired t-test) on the soil before and after phytoremediation had a significant effect on soil lead content (Sig. 1- tailed).

Land use change is an important issue for urban and regional planners and policy makers, but it is also very useful in conservation planning, food security, and hydrological modeling. Data, information and analysis tools become obstacles in detecting changes in land use. With increasing access to data and current technology, it is hoped that land use observations can be carried out in a simple way but have more accurate results. This study aimed to analyze land cover changes in Padang City 2018-2022, using Landsat Imagery and Geographic Information System (GIS) analysis. Firstly, observations on ESRI Land Cover which displays a global map of land use or land cover (LULC) derived from ESA Sentinel-2 Imagery at a resolution of 10 m. The results showed that the area of forest cover has decreased and the built-up area has increased in the 2017-2018 and 2021-2022. Secondly, using the EO Browser, namely Sentinel-2, that was done in one to search for and compare images using high resolution at these sources, there were 19 land cover changes, such as increasing residential land use, while forest land allotment decreased.

Human activities and global warming cause forest fires that impact increasing carbon emissions, destroy forest biodiversity and destroy soil properties. This research is needed to examine carbon storage and soil physical properties on various types of land cover in the Cempaka Forest area, which will later be used as a basis for carrying out restoration and conservation actions. This study used four observation points: Timber Forest Products, Non-Timber Forest Products, Pine, and Shrubs land cover. Carbon storage was measured in the Cempaka forest using the standard RaCSA procedure. The results showed that land cover differences significantly affect the value of carbon storage, with the highest value for storing carbon being the land cover of HHK. However, the difference in land cover did not cause different results on the physical properties of the soil. Correlation and simple regression between the value of carbon storage and other parameters show that carbon storage is strongly influenced by tree biomass and litter, with respective values of 94% and 21%.

Sandy clay loam soil in Bangkalan is a soil with a low content of nutrients, organic matter, bases, and cation exchange capacity (CEC), which inhibits the growth of maize plants. In addition, the nature of the soil causes the fertilizer to become more soluble, and the absorption of nutrients, especially potassium, is low. One of the efforts to increase potassium uptake in sandy loam soils is applying biochar and acid-activated bentonite. This study aimed to examine the effect of adding biochar and acid-activated bentonite to the nutrient uptake of maize plants in the sandy soil of Bangkalan. Biochar was prepared from maize cobs by the Kon-Tiki method; bentonite was activated by physical (200 oC) and chemical (1N H2SO4) methods. The greenhouse experiment was carried out using a completely randomized design with biochar (B) and acid-activated bentonite (T) as treatments, each with three levels, namely 0, 5, 10 t ha-1 and three replications. Soil analysis performed included pH, organic carbon, CEC and exchangeable bases, while plant tissue analysis included leaf height and area. The results showed that the combination of biochar and acid-activated bentonite significantly increased soil pH, soil exchangeable K, soil exchangeable Na, and leaf area of maize plants. A single application of biochar significantly increased soil organic C and maize plant height. The application of acid-activated bentonite significantly increased the CEC of sandy loam soils.
Bangkalan砂质粘土壤土是一种营养物质、有机质、碱和阳离子交换能力(CEC)含量较低的土壤，抑制了玉米植株的生长。此外，土壤的性质使肥料变得更容易溶解，对养分，特别是钾的吸收很低。在沙壤土中施用生物炭和酸活化膨润土是提高钾吸收量的方法之一。本研究旨在探讨在邦卡兰沙质土壤中添加生物炭和酸活化膨润土对玉米植株养分吸收的影响。以玉米芯为原料，采用Kon-Tiki法制备生物炭;膨润土采用物理(200℃)和化学(1N H2SO4)两种活化方法。温室试验采用完全随机设计，以生物炭(B)和酸活化膨润土(T)为处理，分别设0、5、10 T hm -1 3个水平，3个重复。土壤分析包括pH、有机碳、CEC和交换碱，植物组织分析包括叶高和面积。结果表明:生物炭与酸活化膨润土配施显著提高了土壤pH、土壤交换性钾、土壤交换性钠和玉米叶面积;单次施用生物炭可显著提高土壤有机碳含量和玉米株高。施用酸活化膨润土显著提高了砂壤土的CEC。

The price of the AB mix is relatively high, so it needed to find another alternative with a more economical price. One of the alternatives is Liquid Organic Fertilizer (LOF). This study aimed to know the quality of LOF made from banana peels and chicken egg shells, the effect of LOF on the water spinach grown in the hydroponic wick system, and the possible use of LOF as a substitute for AB mix. The experiment consisted of three stages. The first stage was the nutrient analysis of raw materials. The second stage was the production of LOF and nutrient analysis. The results of fermented fertilizers are called POC PT. The third stage was an experiment on water spinach in a hydroponic wick system. The experiment used a completely randomized design with five fertilizer treatments, namely P0 (control), P1 (AB mix nutrition), P2 (LOF PT 150%), P3 (LOF PT 100%), P4 (LOF PT 50%) in three replications. The results showed that LOF, which was fermented for three weeks, had a low nutrient content and was below the Ministry of Agriculture standard. The available N content in POC PT was low, so Ca(NO3)2 fertilizer was added to POC PT. The LOF PT treatment had higher plant growth parameter than the control treatment. Thus, the treatment of LOF PT could not substitute AB mix.

Inefficient fertilization is the cause of decreased rice production. This is due to the inappropriate use of fertilizers. The absence of information on soil nitrogen content in their area causes farmers not to apply fertilizer properly. Analysis of soil nitrogen content in Pamekasan Regency requires much time, cost, and effort. Remote sensing methods can be used to obtain information on soil nitrogen levels by reducing the number of samples used. This study aims to estimate nitrogen content in rice fields using the vegetation index in the form of NGRDI (Normalized Green Red Difference Index). This research was conducted by purposive random sampling method based on 40 land map units formed in Pamekasan Regency, laboratory analysis, statistical analysis, and making distribution maps. The results showed that there was a significant relationship between the NGRDI pixel value and the nitrogen content, with a correlation value of -0.42. The regression equation results obtained from the NGRDI value with nitrogen content are y = -0.269x + 0.139. The accuracy test was carried out by the RMSE method, and the result was 0.027. This shows that the NGRDI index can estimate soil nitrogen content in Pamekasan Regency

Clay minerals are an important indicator of soil plasticity, influencing clay activity. This study aimed to elucidate the effect of clay minerals, organic C and primary minerals on the Atterberg limit and clay activity. The study was conducted in the Kemuning sub-watershed, Jember, East Java. The study began by preparing a thematic map to determine sample points with stratified random sampling. They were taken as many as 35 disturbed soil sample points at 0-20 cm from the surface. Soil texture was determined using the pipette method, and organic C was determined by the spectrophotometer method. The liquid limit and plastic limit were used to determine the plasticity index. A microscopic analysis of sand mineralogy was carried out to compare activity values with a magnification of 20-40 times to assess the primary soil minerals. The results showed that clay and C-organic affect fluidity, plastic limit, and plasticity index. The presence of andesine, albite, olivine, and orthoclase in the sand fraction and the low clay activity indicated that kaolinite dominated the study area, with smaller amounts of illite and halloysite.

They were taken as many as 35 disturbed soil sample points at 0-20 cm from the surface. Soil texture was determined using the pipette method, and organic C was determined by the spectrophotometer method. The liquid limit and plastic limit were used to determine the plasticity index.

The availability of information regarding the cultivation of spice plants is still limited, so studies are needed to support the development of spice plants. This study aimed to identify land characteristics, land suitability classes and distribution maps, limiting factors and recommendations for the development of spice cultivation. The analytical method used was Location Quotient (LQ), and Shift Share Analysis (SSA) to determine the main spice commodities. Overlay and matching between land characteristic parameters and land suitability criteria through ArcGis software version 10.4. The results of the study obtained two main commodities, namely cardamom, with an LQ of 1.98 and ginger, with an LQ of 1.05. Land suitability classes for cardamon are quite suitable (S2), covering an area of 583.89 ha (94.1%) and marginally suitable (S3), covering an area of 36.87 ha (5.9%) with drainage limiting factors, rainfall, base saturation, slope, CEC, pH, and organic C. Land suitability classes for ginger are moderately suitable (S2) with a land area of 541.71 ha (87.3%) and marginally suitable marginal (S3) covering an area of 79.06 ha (12.7%) with the limiting factors of rainfall, temperature, drainage, slope, base saturation, salinity, CEC, pH, and organic C.
