The high salt content in saline soils is the main cause of low salinity soil fertility, especially phosphorus nutrients. The application of phosphate-solubilizing bacteria in saline soil is one method to increase phosphate availability in saline soils. The study consisted of two tests, namely (1) qualitative and quantitative testing of phosphate-solubilizing bacteria in saline conditions and (2) testing of the activity of phosphate solubilizing bacteria in saline soil. This study used Pseudomonas sp. and Bacillus valezensis (Soil Biology Laboratory collection), Inceptisol saline soil from Banongan and Agel Situbondo. The study aimed to determine the activity of phosphate-solubilizing bacteria on the solubility of phosphate in saline soil. The results showed that: (1) Pseudomonas sp. and Bacillus valezensis have a solubility index of 1.25 to 2.68 on solid Pikovskaya medium with some NaCl concentration. Quantitatively test on liquid Pikovskaya medium, water-soluble phosphate concentration about 4.84 ppm to 14.18 ppm and soluble phosphate (extract Bray) between 15.91 ppm to 21.58 ppm. In addition, (2) on saline soil showed that Pseudomonas sp. and Bacillus valezensis could increase phosphate availability by 11.61% to 72,89%. Based on the study results, the genus Pseudomonas sp. and Bacillus valezensis have the potential to increase phosphate availability in saline soils.

The national production of garlic is currently under fluctuations and can not fulfil the demand for garlic. Farmers often face the decline of soil chemical properties that hinder plant growth and yield. Environmentally friendly fertilization alternatives are needed to overcome the problem. This study aimed to find out the effect of Trichocompost and cow manure on soil chemical properties, growth and yield of garlic plants. The results showed that the application of Trichocompost significantly affected the chemical properties of the soil. The application of various Trichocompost and cow manure combinations significantly affected the height of the garlic plant, the garlic bulb weight and the number of cloves. The coefficient correlations (r) between the soil organic C and the number of garlic cloves was 0.42, plant height was 0.26, and garlic bulb weight was 0.36. The coefficient correlations (r) between pH and garlic bulb weight was 0.60, plant height was 0,44, and the number of cloves was 0.48. The coefficient correlations (r) between total N and plant height was 0.02, garlic bulb weight was 017, and clove count was 0.10.

Excessive use of chemical fertilizers in rice fields can reduce soil pH. Elemental P in acid soils is generally not available to plants because it is bound by Fe and Al elements; therefore, it is necessary to make an effort to optimize the availability of P in the soil by improving soil pH with the addition of dolomite lime supported by inorganic fertilizers. This study aimed to determine the effect of dolomite and inorganic fertilizers on plant P uptake, the relationship between available P and phosphate-solubilizing bacteria population, and the effect of dolomite and inorganic fertilizer application on rice yield. This study used a randomized block design with eight treatments and three replications. The results showed that the application of dolomite and inorganic fertilizer had a significant effect on plant P uptake and dry grain weight. The population of phosphate-solubilizing bacteria was positively correlated with the availability of phosphorus in the soil.

Unhealthy agricultural activities possibly caused damage due to pollution from dangerous substances that accumulate as residues. Pesticides can be one of the factors causing soil pollution; one of the reasons is the presence of lead (Pb). This study aimed to elucidate the potential use of sunflower (Hellianthus annus Linn) for phytoremediation Pb contaminated soil. Phytoremediation optimization was upported by the addition of ameliorants in the form of BSF (black soldier fly) compost and biochar. The research was carried out in two stages; the first stage was the utilization of sunflower for phytoremediation of Pb contaminated soil. The second stage was the use of post-phytoremediation soil for planting mustard plants. The results showed that phytoremediation efficiency ranged from 45.74-67.17%, indicating that the sunflower plant was quite effective as Pb accumulator plant. The application of biochar and BSF compost was able to show a higher value than the control treatment to maximize the phytoremediation process. Mustard plants grown on soil that has been remediated showed better growth and biomass yields than that grown on soil that had not been subjected to phytoremediation.

The geographical condition of Ambon City, which is 75% a hilly area resulted in most communities building in marbled areas with slopes above 20%, which has the potential to threaten life and landslide disasters. This study simply looked at the influence of slopes and slope shapes in Ambon City that can be analyzed using geographic information systems (GIS) to map areas that have the potential for landslides. Identification and mapping of potential landslide areas have an important role as an effort in overcoming and anticipating the occurrence of landslide disasters. This study aimed to analyze the spread of potential landslide areas in Ambon City based on the results of SMORPH modeling. The study used the slope morphology or SMORPH method, which has a better degree of accuracy than the Storie Index and SINMAP methods to identify and classify potential landslide areas based on the matrix between slope shape and slope angle. This study resulted in 4 levels of landslide potential areas, namely very low, low, medium and high potential. Areas with high landslide potential dominate the northern and southern parts of Ambon City. In the region, most landslides occur in the form of sunken and convex slopes. The region has a hilly and mountainous topography with a steep slope. The results of this research using the SMORPH method can illustrate that the slope of the increasingly higher slope accompanied by the shape of a convex or concave slope will cause the potential for landslides that are higher in the region.

Maize local of Motorokiki variety is a Gorontalo germplasm which is cultivated more dominantly on sloping land with low productivity. This study was aimed to determine the growth and yield of local maize on several slope classes and doses of NPK fertilizer, and their combination on the growth and yield of local maize in Payu, Gorontalo. This study used a split-plot design with the main plot of slope class and sub-plots of NPK fertilizer dosage. The main plot of the slope class consisted of flat slopes (0-8%), wavy (8-15%), hilly (15-35%) and mountainous (>35%), while sub-plots with NPK fertilizer dosage consisted of 0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1. The parameters measured included plant height, leave numbers, male and female flowering age, cob length, and weight of corn kernels. Data were analyzed by the Duncan Multiple Range Test (DMRT) at 5% level. The results showed that maize growth was significantly affected by slope class and NPK fertilizer dosage with the best combination of wavy slope and 50 kg ha-1 fertilizer dosage. In maize yield, only maize seed weight was significantly affected by slope class, while in NPK fertilization only on male and female flowering age with the best combination of flat slope class and 100 kg ha-1 fertilizer dosage.

Mycorrhizae is a symbiotic relationship between fungi and plant roots that is mutually beneficial. Mycorrhizae can be found in almost all soil types and generally do not have a specific host, but certain factors affect the population level and composition of arbuscular mycorrhizal species, such as plant characteristics and soil chemical properties. This study aimed to determine the density of spores and the percentage of mycorrhizal colonies on several food crops on agricultural land in Jabung District and their relationship to soil chemical properties such as pH, organic-C and available P. The research was conducted from February 2021 to October 2021. Sampling was carried out by purposive sampling based on the grouping of food plant species with six replications. Laboratory analysis was conducted in Biology and Chemical Laboratory, Department of Soil Science, Faculty of Agriculture, Brawijaya University. The results showed that the number of mycorrhizae spores per 100 g of soil was sweet potato (14.17 spores), rice (26.50 spores), cassava (70 spores), and maize (89.17). The percentage of mycorrhizal colonies on sweet potato (33.97%), cassava (50.67%), and rice (45.52%) were in the high category, while the percentage of mycorrhizal colonies on maize (63.68%) was in the very high category. Several mycorrhizae were found, including Glomus sp., Acaulospora sp., and Gigaspora sp.

Drought is one of the most significant impacts of the climate on agriculture, especially food crops. Standardized Precipitation Index (SPI) is an Index for droughts. The research objective was to study the relationship of SPI values to the productivity of rice and corn crops in the Situbondo district. The result showed that the value of the SPI time scale at three months is the most appropriate for the observed productivity of rice and corn. The SPI value significantly correlated with the productivity of rice plants in the Jatibanteng and Arjasa districts but did not significantly affect the productivity of corn in the Mlandingan and Situbondo districts. Furthermore, the El-Nino phenomenon reduced the rice productivity up to 3.9% and the corn productivity up to 48.1%. The La-Nina phenomenon reduced rice productivity up to 26.0% but increased the productivity of corn up to 81.7%.

The geographical location of the Wae Ruhu watershed is in Sirimau District, which is the sub-district with the largest population in Ambon City and is also the center of economic, educational, and industrial activities; this creates economic and population growth that has the potential to trigger land conversion around this area. This study aimed to analyze land cover changes in Ambon City in 2012, 2017, 2022 and predict land cover in 2031. This study used Cellular Automata Markov Chains modeling to predict land cover changes in 2031. The results showed that the types of land cover are built and land cover. The open area continues to increase in area, while agricultural and non-agricultural areas continue to experience a decrease in area, and water bodies do not experience a decrease or increase in area. The results of land cover predictions in 2031 showed that the built-up area is 345.79 ha, open land is 121.18 ha, agricultural land is 657.35 ha, non-agricultural land is 507.65 ha, and water bodies are 11.46 ha. The results of this study are expected to be used as a reference in making policies related to spatial planning and utilization, especially the Wae Ruhu watershed and can optimize sustainable watershed management as the first step in efforts to mitigate natural disasters.
