Bulukerto Village, Bumiaji District, Batu City is a village that is famous for its apple farming, but currently, the productivity of apples has decreased. The area of Arabica coffee plant development in Bulukerto Village is still not optimal. The purpose of this study was to evaluate the potential for developing arabica coffee plants based on the level of land suitability in Bulukerto Village, Bumiaji District, Batu City. The determination of sample points was based on the Land Map Unit and continued with soil sampling. The indicators observed in this study were water availability (wa) which consisted of annual rainfall and dry month length, altitude (h), slope (eh), root media (rc) which consisted of effective depth and soil texture, rocks in surface (s), drainage (oa), nutrient retention (nr) consisting of pH, organic C and cation exchange capacity, then available nutrients (n) consisting of total N, available P, and exchangeable K. Data analysis for actual land suitability used the method of comparing or matching data between actual land conditions and growing conditions for Arabica coffee plants. The results showed that the land condition in Bulukerto Village, Bumiaji District, Batu City, in general, has the potential for developing Arabica coffee, with potential land suitability indicating that an area of 438,77 ha of land has class S1 (suitable) and an area of 82,62 ha of land has class S2 (moderately suitable) with some limiting factors.

Soil thickness has a significant influence on many of earth surface processes, and it can be mapped using various methods. Digital soil mapping can be used to estimate the spatial distribution of soil thickness and can estimate the uncertainty of the soil prediction map. Digital soil mapping using regression methods such as Multiple Linear Regression (MLR) and Regression Krigging (RK) was used to estimate soil thickness of the slope of Bener Reservoir. Bener Dam is a national strategic project which is built for irrigation to improve farming quantity. The aim of this research was to determine the spatial variation of the soil thickness at the slope of Bener Reservoir. The accuracy of MLR and RK were compared to select the best soil thickness prediction. There were 212 and 53 soil thickness samples from fieldwork which were used for data training and testing, respectively. There were 5 environmental variables such as elevation, distance from river, slope, plan curvature, and topographic wetness index. R programming language with gstat, krige, and stats Packages was employed for MLR and RK prediction. The result showed that KR is more accurate than MLR.

Various crop commodities are grown in Ngawonggo Village with various land uses, including rice fields, dry fields and agroforestry which are dominated by intensive agriculture. As a result, this agricultural pattern can potentially cause land degradation. One of the technological inputs in improving sustainable crop production systems is the application of mycorrhizal biofertilizers. This study aims to determine the level of population, mycorrhizal colonies and types of spores and the factors that influence them in rice fields with rice (Oryza sativa), dry fields with sengon (Paraserianthes falcataria), and agroforestry with coffee (Coffea sp.) and Durian ( Durio zibethinus). The study used a randomized block design with sampling on three land uses, with 5. The results obtained only one type of mycorrhizal spore of Glomus sp. on all land uses. The highest number of spores was in agroforestry land use, as much as 102 g-1 soil, and the lowest was in rice fields, as much as 10 g-1 soil. Mycorrhizal colonies on plant roots were the highest in agroforestry land use, it was found that 42.77% of coffee roots were colonized by mycorrhizae, followed by durian with a colonization proportion of 42.29%, rice fields with commodities had the lowest colonization proportion of 16.21%.

Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.

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.
Tuban Regency感受到了气候变化对各个经济支持部门的影响。因此，这些部门的适应努力以及减缓气候变化以支持减少温室气体排放十分重要，其中之一就是维持生产林的存在。本研究旨在确定两种主要植物的碳吸收量。采用的方法是采集树径数据而不采伐。利用直径数据用异速生长方程计算生物量和固碳量。结果表明:柚木5岁时生物量最低，为94.26 t ha-1; 10岁时生物量最高，为200.33 t ha-1;5年、10年和15年的红木总生物量分别为40.76 t ha-1、53.55 t ha-1和146.37 t ha-1。从生物量值看，5年、10年和15年柚木的总碳储量分别为43.36 t ha-1、92.15 t ha-1和90.05 t ha-1。5年、10年和15年的红木总碳储量分别为18.75 t ha-1、24.63 t ha-1和67.33 t ha-1。该年龄组柚木和红木生产林的总面积超过280公顷，因此BKPH孙都兰的总固碳量为柚木生产林的78,471吨碳，吸收红木生产林的1835.3吨碳。

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.","PeriodicalId":413872,"journal":{"name":"Jurnal Tanah dan Sumberdaya Lahan","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121853799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Onion has become one of the popular horticulture commodities in Indonesia due to the crop having several benefits. Consequently, the demand for onions in Indonesia increases annually. In contrast, the supply of onion fluctuates because of unstable onion production. One of the factors that affect unstable onion production is soil fertility degradation. Therefore, the study aimed to analyze the effect of different doses of inorganic fertilizer compounds on the chemical properties of soil, plant growth and production. The field research was conducted in the experimental land of the Faculty of Agriculture, Brawijaya University, located in Jatimulyo Village, Lowokwaru District, Malang City. This study could not detect a significant difference in fertilization doses on onion plant growth but could increase the yield and tiller numbers. The highest values of tillers number, tuber fresh weight and tuber dry weight were observed for the treatment of 50% basal fertilizer + 150% compound inorganic fertilizer and the lowest production of biomass, tillers number, wet weight, and tuber dry weight was on treatment control.
