Abstrak.Pengukuran kadar air tanah pada areal perkebunan kopi yang luas dengan metode tradisional sangat sulit, memerlukan banyak tenaga kerja, biaya yang mahal, dan waktu yang lama. Indeks kadar air tanah (SMI) dapat diidentifikasi dengan metode penginderaan jauh, dengan menggunakan data algoritma dari sensor satelit seperti suhu permukaan tanah (LST) dan indeks vegetasi (NDVI). Penelitian ini bertujuan untuk menganalisis status kadar air tanah menggunakan Indeks Kadar Air Tanah (KAT), untuk mengetahui hubungan antara NDVI, SMI dan produksi kopi pada perkebunan kopi rakyat di Karangploso, Kabupaten Malang. Penelitian ini dilakukan dengan observasi lapangan dan analisis laboratorium. Terdapat sepuluh plot pengamatan pada areal perkebunan kopi Robusta rakyat. Hasil penelitian menunjukkan bahwa: (1) Nilai SMI pada perkebunan kopi rakyat bervariasi pada kisaran 0,65-0,94 (kategori Tinggi Sangat Tinggi). (2) Nilai SMI (Metode Citra) merupakan prediktor yang baik untuk memperkirakan kemampuan tanah dalam menyimpan air tersedia (AWC, Available Water Capacity) (r= 0,7491**). (3) Nilai NDVI pada perkebunan kopi rakyat bervariasi pada kisaran 0,26-0,48 (kategori Rendah Tinggi). (4) Nilai SMI (Image Method) berkorelasi signifikan dengan nilai SMI (Field Method) (r= 0,8154**). (5) Nilai NDVI dan SMI (Image Method) merupakan prediktor yang baik untuk menduga produksi kopi, model regresinya adalah: Prod = 147,4571 + 876,3815SMI (Image) + 1203,327NDVI (R2= 0,6646; Sig F= 0,00009).Soil Moisture Index To Estimate Water Availability In Coffee Gardens In Karangploso District, Malang RegencyAbstract. Soil moisture measurements for large areas of coffee plantation using traditional methods are very difficult, labor intensive, highly costs, and time consuming. Soil moisture index (SMI) can be identified with the remote sensing methods, using algorithm data from satellite sensors such as land surface temperature (LST) and vegetation index (NDVI). This research aimed to analyze soil moisture status using Soil Moisture Index, to know the relationship between NDVI , SMI and coffee production in smallholder coffee plantation in Karangploso, Malang regency. This research was conducted by field observation, and laboratory analysis. There were ten observation plots at the area os smallholder Robusta coffee plantation. Results of this research showed that: (1) The SMI value in smallholder coffee plantation varied in the range of 0.65-0.94 (High Very High category). (2) The SMI value (Image Method) was a good predictor for estimating the soil's ability to store available water (AWC, Available Water Capacity) (r= 0.7491**). (3) The NDVI value in smallholder coffee plantation varied in the range of 0.26-0.48 (Low High category).

Abstract

This study investigates the land conversion rate and household food security in Bakalan Village, Pasuruan Regency. Data was collected through primary surveys, including detailed observations of land conversion and structured interviews with various residents, including ordinary households, farmer households, and farmer households with land conversion. The research employed quantitative methods to analyze the rate of land conversion and its implications on food security. Specifically, the study quantified the extent of land conversion and evaluated household food security using indicators such as food expenditure and energy consumption ratios. The findings revealed a substantial % land conversion rate of 50% between 2020 and 2021. This conversion was predominantly economically motivated, largely due to the influx of industrial development in the area. Significantly, converting land use from agriculture to industrial areas profoundly affected food security. The study found that overall food security in the village was compromised, with most households consuming less than the standard of 114.6 kg per person per year. This below-standard consumption was directly linked to energy deficiencies among the population. The results of this study underscore the urgent need for policy interventions that balance economic development with food security and sustainability. This research contributes to the broader discourse on land use planning and its critical implications for agricultural productivity and food security. These findings also provide valuable insights for policymakers, suggesting that development strategies should include provisions for safeguarding and enhancing food security in regions undergoing rapid industrialization. This study sets a foundation for future research in agricultural economics by illustrating the intricate connections between land use dynamics and food security outcomes. Keywords: agricultural economics, household food security, industrial development, land conversion rate

Abstract

Purwodadi Botanic Garden is one of the botanic gardens in Indonesia, located in Pasuruan, East Java. Purwodadi Botanic Garden (PBG) is an ex-situ plant conservation area that serves five main functions: conservation, research, education, ecotourism, and environmental services. Purwodadi Botanic Garden features a living collection of plants, primarily terrestrial, but also includes aquatic species. Therefore, this study aims to conduct water quality monitoring in aquatic plant ponds and present the experiments of phytoremediation on selected species of aquatic plants. This research employs a mixed-methods approach, combining qualitative and quantitative methods. Data were obtained from direct observation of aquatic plants in the garden, monthly monitoring of water quality in 32 ponds, and the results of phytoremediation experiments from research activities spanning over ten years. Monitoring water quality using water-test kits is inexpensive, easy to use, and yields results quickly. Parameters measured for environmental quality are temperature, humidity, light intensity, pH, TDS, and water temperature. The results show that, out of 32 ponds in the garden, only 12 ponds were found to have aquatic plants. The water quality in ponds with aquatic plants is generally better than in those without aquatic plants, indicating that the aquatic plants in ponds act as phytoremediators in the effort to improve water quality. Purwodadi Botanic Garden contains 25 species of aquatic plants. However, during the observation of the pond, only 15 species of aquatic plants were present. The results of the experiments selected 10 species as phytoremediation agents for both organic and inorganic pollution. The 10 species are Acanthus ilicifolius, Actinoscirpus grossus, Ceratophyllum demersum, Coix lacryma-jobi, Echinodorus radicans, Lemna minor, Ludwigia octovalvis, Pistia stratiotes, Sagittaria lancifolia, and Salvinia molesta.

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

As one of the regions with the potential to become a national food production center, Kediri District in East Java has initiated the implementation of an organic farming system. To ensure the long-term viability of this agricultural system, it is essential to assess its level of sustainability. The objective of this study is to conduct a sustainability analysis to ascertain the status of sustainability and optimization strategies for IPM rice farming in the district. The research was conducted in Kediri District, with samples of Sugihwaras Village and Pandantoyo Village, involving a total of 100 respondents. These respondents were then interviewed to measure the six dimensions and 51 attributes used in the study. The data was analyzed using Multidimensional Scaling (MDS) RAP-IPM, and a prospective analysis was subsequently conducted. The results indicate that the sustainability scores for each dimension are as follows: ecology (83.29), technology (78.21), policy (81.31), and institutional (79.31), which suggest a very sustainable status. In contrast, the social dimension (60.19) is moderately sustainable, while the economic dimension (38.92) is classified as less sustainable. The average value of all these dimensions is 70.2, which can be considered quite sustainable. Within each dimension, there are sensitive attributes that are related to its sustainable status. These attributes are a key factor in the formulation of implementation strategies to encourage food security in Kediri District. The prospective analysis of the key factors indicates that most of these factors are situated in Quadrant II, signifying a high level of influence and dependence. To promote resilience effectively and efficiently in Kediri District, it is essential to prioritize strategies that consider the pivotal factors within Quadrant II.

Abstract

The increase in land limitation as a living space triggered the higher price in the Malang area, thus becoming unaffordable for low-income communities. This problem causes the shift of land choices to the border area, as happened in the Singosari sub-district. But unfortunately, the trend of housing as a current model of housing development will impact the reduction of land space, land conversion, slums, reduced water catchment area, etc. The development of flats is considered to be more appropriate for the sustainable development concept. This study aims to determine the community interest and to know the level of economic affordability for the development of a flats model, especially for low-income communities in Singosari. To support this research, we made 2 designs of flat buildings. This research was conducted at Bumi Mondoroko Raya housing (37.62 Ha). This housing focuses on providing living housing for low-income communities.  We use a descriptive qualitative method and quantitative methods through the distribution of questionnaires. The result shows that the community can not accept the house with the flats model, although they can reach the selling price of flats as 95.24% economically by utilizing the subsidized mortgage for 20 years. Keywords: Flats, Low Income Community, Interest
