Abstract

Coffee plants (Coffea sp.) are among the most popular plantation crops for farmers in Wajak District. However, the soil condition in Wajak District is dominated by sandy soil, which can trigger soil sensitivity to high erosion potential. A mitigation effort for the declining of coffee production in the Wajak District can be made through the estimation of the soil erodibility index. This study aimed to suspect the soil erodibility index and obtain the relationship of soil erodibility index to coffee production on smallholder coffee plantations in Wajak District, Malang Regency. The methods of determining land boundaries with land map units (SPL) were land use, soil type, and slope. The parameters used were soil texture (M), organic matter (a), structure (b), and permeability (c) to determine erodibility, as well as coffee beans for coffee production analysis. Statistical analysis of data was in the form of correlation tests and data regression tests. The results of the data analysis showed that the highest wet weight of coffee fruit was found in SPL 8 with plantation land use, Typic Hapludands soil type and land slope of 8-15%. The wet weight value of coffee fruit at SPL 8 is 2.18 t ha-1 with an erodibility value of 0.37. While the lowest wet weight of coffee beans was found in SPL 2 with moor land use, Andic Eutrudepts soil type and land slope of 8-15%. The average wet weight value of coffee beans at SPL 2 was 0.12 t ha-1 with an erodibility value of 0.26.

Abstract

One of the efforts to manage the risk of ground movement is to identify landslide-prone area characteristics. This study aimed to investigate the geophysical, geotechnical, and vegetation characteristics of landslide and non-landslide areas. This study adopted the resistivity geoelectric method to identify the type and structure of subsurface materials in landslide and non-landslide regions in Pujon and Ngantang, Malang Regency. Measurements in this study were done in four locations. Each geoelectric measurement path at each location was determined to be 100 m long. The electrodes were spaced apart by 10 m for measurements between the current electrode and the potential electrode. The dipole-dipole configuration of the geoelectric survey trajectory is determined based on the former landslide event to predict underground material. In addition, an investigation of geological, geotechnical, and vegetation characteristics was carried out. The results showed that the geophysical, soil, and vegetation characteristics of the landslide and non-landslide slopes were similar. The geophysical characteristics of the soil in all study locations indicate the presence of a slipping surface, which makes the land prone to landslides. The slipping plane was formed due to differences in the types of rocks between the surface and deep layers. The existence of vegetation has an important role in landslide management. Non-landslide areas tended to have denser tree vegetation and a higher number of shrub species.

Abstract

Ultisols, including those of Langsa, Aceh, are known to have low fertility due to low pH, low available nutrients, low base saturation, high pH and exchangeable Al, and low cation exchange capacity. These problems can be alleviated by applying organic amendments to the soil. One of the soil amendments is biochar. This study aimed to elucidate the potential of oil palm and cacao waste biochar for improving the chemical properties of an Ultisol of Langsa, Aceh. Biochars generated from oil palm kernel shell (PKS), oil palm empty fruit bunch (PEFB), and cacao pod husk (CPH) were applied to the soil and incubated in the laboratory for 16 weeks. At 4, 8, 12, and 16 weeks after incubation, the changes in soil chemical properties were measured. The results showed that applying different types of biochar significantly improved the chemical properties of the Ultisol of Langsa. Specifically, PEFB biochar caused significant increases in soil pH (H2O and KCl), total phosphorus, available phosphorus, organic C, and cation exchange capacity. These increases became more pronounced with longer incubation times. In addition, using PEFB biochar resulted in the lowest levels of exchangeable Al and Fe in the soil. These levels decreased further with longer incubation times. In general, PEFB biochar produced at a pyrolysis temperature of 450oC for 4 hours is the most effective biochar for improving the chemical properties of the Ultisol of Langsa.

Abstract

Agriculture land shows soil compaction problems due to long-term agricultural cultivation activities. Soil compaction indicator can be seen from the value of soil penetration resistance at different soil depths (0 - 60 cm). This research aimed to determine soil penetration resistance at different coffee plantation ages with different soil depths and to analyze the relationship between soil penetration resistance with soil physical characteristics and coffee productivity. The survey activities include observation of minipits, measuring soil penetration resistance at soil depths of 0-20 cm, 20-40 cm, and 40-60 cm using a hand penetrometer, and soil sampling. The results showed that the soil penetration resistance at each LU and soil depth suggested variation were categorized into moderate and high soil penetration resistance classes (1.34 MPa - 3.35 MPa). Soil characteristics, such as soil aggregate stability, water content, bulk density, porosity, silt content, and clay content, significantly correlate with soil penetration resistance. However, soil penetration resistance has a negative correlation with coffee productivity. The value of soil penetration resistance (at a depth of 0-60 cm) has a significant negative correlation with the average productivity of coffee plantations (r=-0.5936**). Therefore, increased soil penetration resistance decreased root growth, decreasing plant productivity.

Abstract

System Dynamics serves as an approach to unravel behavioral patterns by exploring fundamental structures. In this study, the dynamic system was crafted using STELLA software. The research methodology involved conducting primary surveys with both farmers and conversion farmers' households to gather essential data on their perspectives, practices, and circumstances related to land conversion and food security. Through this data, the System Dynamic model was constructed to depict the interplay among key variables impacting food security, specifically focusing on Food Availability, Affordability, and Needs. The analysis revealed that the Food Affordability indicator consistently played a pivotal role in shaping these trends over the analyzed years. However, a significant discrepancy in food security levels emerged between farming and non-farming households. This divergence primarily stemmed from income inequalities within the agricultural sector, affecting the purchasing power for essential foods like rice across the village. Additionally, a concerning trend of diminishing agricultural land and a subsequent decline in food availability was observed.

Abstract

The land use and land cover change phenomenon has brought social and economic benefits such as agricultural land expansion, which increases food production for a rapidly growing population. On the other hand, it has also been reported to impact terrestrial ecosystem change and its service, including climate change control. The study aimed to estimate CO2 emission from land use and land cover change in Banyuwangi during 1995–2019 and formulate mitigation options to reduce CO2 emission. Four satellite images from 1995, 2000, 2014, and 2019 were used to classify land use and cover and then investigate the changes. This study applies a historical-based approach to estimate emissions to project future emissions using REDD Abacus SP software. There are 12 land use and land cover based on supervised classification: primary forest, secondary forest, plantation forest, mangrove forest, plantation, settlement, cropland, paddy field, shrubs, water, fishpond, and barren land. The land use and land cover change during the period 1995 to 2019 increased both CO2 emissions and sequestration. From 1995 to 2019, land use and land cover change in Banyuwangi emitted 1,5 million tons of CO2-eq/yr and sequestered 0,5 million tons of CO2-eq/yr. Under Business as Usual (BAU) or without mitigation effort, the emission will decrease to 1,2 million tons CO2-eq/yr in 2030. The implementation of the Regional Spatial Plan (RSP) prepared by the Banyuwangi Regency Government is projected to reduce emissions by 47.59% of net emissions from emission without mitigation. If the RSP scenario is added with efforts to prevent deforestation, net emissions can be reduced by 89.21%. Implementing Banyuwangi RSP can become best practice mitigation because it prioritizes the balance of protected areas and cultivation and maintains economic growth.

Abstract

The use of mangrove fruit to create economic benefit for the community is anticipated to bolster conservation efforts for the mangrove environment. In Mandar Banyuwangi Village, one application of mangrove fruit is its conversion into flour. This study aimed to examine the proximate composition of Rhizophora mucronata mangrove flour and evaluate the profitability of processing this flour into pastries. The analysis conducted encompasses the proximate content test (including protein, fat, water, ash, and carbs) and a profit analysis that factors in the cost of goods sold (COGS). Mangrove flour manufactured by Poklahsar “Mina UPA Karya” is derived from the fruit of Rhizophora mucronata. The processing method necessitated seven days to manufacture mangrove flour. The proximate composition of mangrove flour, as per SNI criteria, includes water and carbohydrate content, although protein, fat, and ash content are marginally over or below SNI specifications.  Mangrove flour is utilized in a variety of desserts, including nastar, kastengel, cookies, almond chocolate, roses, jam sumprit, chocolate sumprit, peanut cake, and krispi brownies. Products made using processed mangrove flour in pastries yield a profit margin of 9.16% of the cost of goods sold (COGS). The R/C, BEPs, BEPq, profit, and profitability ratio of the mangrove flour processing business indicate profitability, since they go over the minimum requirements of profitability criteria.
