Tuban Regency feels the impact of climate change on various economic supporting sectors. This makes the adaptation efforts in these sectors important as well as climate change mitigation to support the reduction of greenhouse gas emissions, one of which is by maintaining the existence of production forests. This study aims to identify the amount of carbon uptake by the two main plants. The method used is tree diameter data collection without harvesting. The diameter data is used to calculate biomass and carbon sequestration with allometric equations. The results showed that teak had the lowest biomass value produced at the age of 5 years at 94.26 t ha-1, and the highest biomass was recorded at the age of 10 years at 200.33 t ha-1. Meanwhile, mahogany at the age of 5 years, 10 years and 15 years had a total biomass of 40.76 t ha-1, 53.55 t ha-1 and 146.37 t ha-1, respectively. From the biomass value, the total carbon stored in teak aged 5 years, 10 years and 15 years, respectively, was 43.36 t ha-1, 92.15 t ha-1 and 90.05 t ha-1. While the the total carbon stores in mahogany aged 5 years, 10 years and 15 years respectively was 18.75 t ha-1, 24.63 t ha-1 and 67.33 t ha-1. The teak and mahogany production forests in this age group have a total area of more than 280 ha, so that the total carbon sequestration at BKPH Sundulan is 78,471 tons C from teak production forests and 1,835.3 tons C absorbed from mahogany production forests.

The main commodity of food crops cultivated in Indonesia is rice, but rice productivity in Indonesia has decreased. Factors that cause a decrease in rice productivity are land conversion that continues to increase and unbalanced fertilization. Efforts to increase rice yields are by applying a combination of inorganic fertilizers and biological fertilizers. Otherwise, this study focused on studying the effect of the application of a combination of inorganic fertilizers and biological fertilizers on several soil chemical characteristics and rice production in the experimental field of the Faculty of Agriculture, Jatimulyo District, Malang City. Application of biological and inorganic fertilizers with analysys of variance (ANOVA) showed a significant effect on chemical characteristics parameters such as pH and available P. Otherwise, this research showed a significant effect on production, such as the weight of biomass and milled dry grain harvested. Based on this research, the best combination fertilizer is T3 (75% basal inorganic fertilizer + 100% biological fertilizer).

Rice production in Pamekasan Regency from 2011 to 2019 decreased by 38.71% due to farmers applying fertilizers that did not match plant needs, such as insufficient application of manure, organic fertilizers and other inorganic fertilizers. In addition, the basic fertilization obtained by farmers comes from informal information, so the application of fertilizers on the land is not efficient. Efforts have been made to overcome these problems by evaluating soil fertility from the aspect of nutrient retention as a basis for determining fertilizer requirements. The purpose of this study was to evaluate soil fertility, especially from the aspect of nutrient retention in paddy fields in Pamekasan Regency. This research used a purposive random sampling method based on SPL (Land Map Unit). Parameters observed were cation exchange capacity, organic C, base saturation, pH, electrical conductivity, texture, porosity, bulk density and saturated hydraulic conductivity. The results showed that the high level of soil fertility in Pamekasan Regency was found in cation exchange capacity in Tlanakan District (43.92 cmol kg-1), base saturation in Galis District (99.38%), pH in Tlanakan District (7.00), electrical conductivity in Pakong and Pasean districts (0.39 mS) and the dominant texture is the clay fraction. Low fertility levels are found in soil organic C in Waru and Kadur Districts (0.08%), bulk density in Pasean District (1.59 g cm-3), porosity in Proppo District (34.89%), and saturated hydraulic conductivity in Pasean District (46.34 cm hour-1).

Water is one of the limiting factors in the growth of coffee plants. If plants experience a lack of water, it can inhibit plant growth and, at a critical level, can lead to drought stress and plant damages. The available soil water to plants can be estimated from the level of soil moisture index. The monitoring of soil moisture status can be used in improving the management of coffee plantations. Soil Moisture Index (SMI) is a method that can be used to estimate the level of soil moisture using remote sensing technology using NDVI and LST values. The purpose of this study was to analyze the status and distribution of soil moisture at the coffee plantation; analyze the relationship between vegetation index and soil moisture; and analyzed the relationship between soil moisture status using the SMI method and soil moisture measured in coffee plantations. Results showed that the soil moisture index obtained from Landsat 8 OLI/TIRS image processing had an average value of 0.60. The average soil moisture index at the study site is 1.05. Soil moisture index from the Landsat 8 OLI/TIRS image has a significant positive effect on soil moisture at the study site (y = 7.4996x â€“ 3.4789; R2 = 0.7146**). Â It is suggested that the SMI method can be used to estimate soil moisture in the coffee plantation.

The uneven distribution and intensity of rain cause a shortage and excess of water in dry land farming. It appears that the problem of soil conservation in principle is the regulation of the relationship between rainfall intensity, infiltration capacity, and runoff adjustment. To improve the physical properties of the soil, and the hydrological function of the land use it cannot only be stressed on the coffee plant. Other factors such as soil surface management, such as providing organic matter, covering the soil surface with understory plants, making absorption holes, terraces, waterways and so on, can improve the hydrological function of the land. Rainwater management can be carried out through controlling surface runoff, harvesting rainwater, increasing soil infiltration capacity, managing soil, controlling evaporation and seepage, lining waterways. The use of silt pit parallel is considered quite effective because it is able to produce the lowest surface runoff and sufficient water storage. Silt pit parallel can produce 0.6% of rainfall into surface runoff and also can store water as much as 62.35% of the rainfall that enters the plot. The functions of a silt pit are to increase water infiltration into the soil. On dry land, silt pit functions as a place for harvesting rainwater and surface runoff. Based on the correlation regression test, the amount of surface runoff is closely influenced by the intensity of rain or rainfall.
