The main problem in the Indonesian rubber plantations is white root rot disease (Rigidoporus microporus). White root rot disease causes the death in rubber so that the amount of crop production declines. The growth of white root rot in the soil is influenced by the nature of the soil itself that include Â soil physical, chemical and biological properties. It is known that the white root rot disease likes porous soils. The purpose of this study was to determine the effect of soil physical properties on Â the intensity of white root rot disease attacking the roots of white rubber plant. The study was done by calculating the intensity of disease and soil sampling for analysis in laboratororium. The results showed that the physical properties of soil that influenced the intensity of white root rot was organic matter 10.75%; clay fraction 30.53%; pH 30.8%; available moisture 40.69%; sand fraction 41.9% and porosity 73.37%. However, the porosity of the soil had a very strong influence and it was highly significant (p <0.01) with the regression equation y = 226.32 - 5,0311x. The high porosity of the soil was able to suppress the intensity of white root fungus attacks.

The coffee is not only a drink but also become a life style which is increase the consumption of coffee, but the production of coffee in Indonesia is still low. Lahat District classified as an agricultural area with the coffee plant area covering 51.788 ha and the coffee production is 19.692 tons, viewed from the area, the coffee production is still relatively low (BPS Lahat, 2016). The formulation of policies for the development of agricultural areas required the support of information systems such as maps, by utilizing the Geographic Information System (GIS) integrated with the Land Conformity Assessment System (SPKL) program. The purpose of this research is to know the suitability level of robusta coffee plant land, to analyze the availability of land for the development of robusta coffee plant and to arrange the development of robusta coffee plant in Lahat District. The method used in this research is spatial analysis and mapping using GIS integrated with SPKL and field verification activities. The result of this study is Lahat District has a suitability class of coffee plantation including marginal and unsuitable, with 4 limiting factors identified. Lahat District is dominated for intensification with percentage of 76% with 122,140 ha, extensification with 23% percentage with 37,714 ha and diversification with 1% percentage with 2,148 ha area.

This study that was aimed to get the land suitability class of red chili in Lamongan Regency, and determining the area that suitable to plant the red chili in rainy season, was done at Balai Besar Sumberdaya Lahan Pertanian Bogor, West Java and Lamongan Regency, East Java. This study was conducted using the integration between Geographic Information System (GIS) and Land Suitability Scoring System (LSSS). Based on LSSS program running and data that joined in ArcGIS, the results showed that there are three land suitability classes for red chili in Lamongan Regency, i.e. S1 (very suitable), S2 (fairly suitable), S3 (marginally suitable), and N (not suitable). The above classes also have the limiting factors, i.e. slope (eh1), soil texture (rc2), and soil depth (rc4). The total amount of land availability based on the forest area status, on the APL area is 153.329 ha, while that on the HP area is 29.923 ha. The total amount of land availability based on the land licensing, on the PTL area is 14.543 ha, and that on the NPT area is 151.906 ha. The area recommended for planting red chilli in the rainy season is 160.728 ha.

Verification of oil palm plants is done to cross check with census data on the number of plants to find out the number of oil palm plants in each. Unfortunately the company still has difficulty detecting the amount of palm oil in each block. One effort to overcome this problem is to use GIS (Geographic Information System). The purpose of this study was to determine the effect and differences in the use of photogrammetric methods with the waypoint method, the role of GIS (Geographic Information System) and determine the number of oil palm trees to be planted in the blocks in Afdeling I and Afdeling IV. This research through the preparation stage by preparing a sub-block map and flight plan, data collection stage by collecting aerial photo data, waypoint, block SHP, information on block area, planting year information and initial basic information on oil palm, the data processing stage using the mosaicking approach on the Agisoft PhotoScan Propessional application, waypoint conversion with Global Mapper and overlaying aerial photos with a waypoint with ArcMap 10.3. The results showed that the waypoint using GPS had higher accuracy compared to aerial photography and had an effect on the overlay results at the planned waypoint distance with the initial principal palm oil object. GIS is useful for processing aerial photo data and waypoints from GPS, and can speed up side verification. The plan is to insert in the B37 Block as many as 462 principal, B38 Block as many as 928 principal, B39 Block as many as 1,611 principal, B40 Block 351 principal, Block D29 1,063 principal, D30 Block 1,085, A53a Block 2,665 principal, A55a Block 539 subjects , C55 Block as many as 371, C56 Block as many as 510 principal, D55 Block as many as 157 principal, D56 Block as many as 375 principal, D57 Block as many as 1,561 and Block D59 with 1,431.

Citrus plants (Citrus sp.) are most plants that grow in Petungsewu Village, Dau District. The decreased productivity of citrus plants causes the availability of citrus plants also to decrease. This needs to be increased to meet citrus plants' needs. The influence of soil organic matter is the main factor causing a decrease in the productivity of citrus plants in Petungsewu Village, Dau District. Therefore, it is necessary to estimate soil organic matter using the NDVI vegetation density index to obtain adequate and efficient results. Reliability testing was also carried out to know the accuracy level of the estimates made. The research was conducted at the Citrus Plantation and Subtropical Fruit Research Institute in Petungsewu Village, Dau District, Malang Regency. Estimation of soil organic matter using the NDVI vegetation density index showed an accuracy rate of 81.1%. The results of the accuracy analysis were strengthened by the presence of a paired t-test with a value of t = 0.01 and a value of p = 0.991.

The decreasing land area for coffee cultivation in Indonesia has led to a reduction in coffee production. The availability of land with potential for coffee plantation is also decreasing. As a consequence, coffee is cultivated on less fertile lands, such as lands dominated by clay fraction. This land generally has a low pH so that the nutrient content is more absorbed in Al and Fe which react in an acidic environment. Furthermore, heavy texture of soil also inhibits root growth, making it difficult for plants to absorb nutrients. In this study, biopore infiltration holes were used as a solution to improve acidic soil with a dominant clay fraction. The research was conducted at Agrotechnopark Jatikerto, Malang Regency and the soil analysis was conducted at the Soil Chemistry Laboratory, Faculty of Agriculture, University of Brawijaya during 2020-2022. This research was conducted experimentally with a group randomized design. There were four treatments in this study, namely 1) control/no biopore, 2) 30 cm empty biopore, 3) 30 cm biopore + 2.12 kg compost fertilizer, and 4) 30 cm biopore + 1.05 kg goat manure fertilizer. The results showed that biopore infiltration holes added with compost or goat manure fertilizer were able to increase pH, soil organic C, CEC, BS, and total N-P-K nutrients. Furthermore, the increase in organic C and total N-P-K nutrients in the study area was also directly proportional to the increase in chlorophyll content and coffee production. The increase in chlorophyll content and coffee production is a result of the increase in chlorophyll content and coffee yield.
