Abstract

The characteristics of siamese oranges have a 30% part in the form of fruit peel which has not been used and discarded, however, siamese peel has pectin content that can be utilized as an edible coating. The purpose of this research is to determine the effect of using pectin compounds of chayote peel as edible coating on the quality of strawberry fruit during the shelf life. The research method was conducted using a 4x4 factorial complete randomized design with factors of chayote peel pectin concentration and storage temperature. The first factor is the concentration of edible coating from pectin which consists of 4 levels, namely 0%, 1%, 2%, and 3%. The second factor is the length of storage, consisting of 4 levels, namely 3, 6, 9 and 12 days of storage at refrigerator temperature (14oC). The variables observed include weight loss, texture, vitamin C content, pH test, total soluble solids and organoleptic (color, taste and appearance). Based on the analysis of variance, the treatment of pectin concentration comparison of siamese orange peel as edible coating on the shelf life of strawberry fruit has a significant effect (p

Abstract

Perbedaan nilai harga tanah menghasilkan ketidakseimbangan harga yang berdampak pada selisih harga yang signifikan dalam lingkup wilayah yang berdekatan. Oleh karena itu, diperlukan peninjauan harga untuk mengatasi hal tersebut. Metode yang digunakan dalam penelitian ini meliputi analisis spasial berupa analisis interpolasi, analisis proximity sarana dan prasarana, dan analisis zonal statistik. Analisis AHP dibuat dengan data aksesibilitas, pusat pelayanan, dan pola ruang. Analisis proximity dan AHP digunakan sebagai input regresi untuk mengetahui estimasi nilai ZNT dan persebarannya. Hasil penelitian menunjukan persebaran harga tanah di Kecamatan Lowokwaru dengan rentang harga rata-rata antara Rp.2.500.000 hingga Rp.7.000.000. Mayoritas harga tertinggi terdapat di Kelurahan Lowokwaru, Mojolangu, dan Sumbersari dengan harga di atas Rp.7.000.000, sedangkan Kelurahan Merjosari memiliki harga rata-rata paling rendah yaitu di bawah Rp.2.500.000. Analisis regresi linier berganda menunjukkan nilai R-square 34,20% dimana masih ada 65,80% faktor yang belum diketahui peneliti terkait pengaruh terhadap harga tanah di Kecamatan Lowokwaru. Penelitian ini menyimpulkan bahwa dalam menentukan harga tanah di Kecamatan Lowokwaru, masyarakat tidak memperhatikan faktor kedekatan sarana dan prasarana. Hasil analisis dan visualisasi estimasi harga tanah membentuk zona-zona harga sehingga membantu menciptakan zona-zona harga yang homogen di wilayah Kecamatan Lowokwaru.

Abstract

This study introduces a ground-breaking method for enhancing urban energy management by integrating high-resolution night-time satellite imagery from SDGSAT-1 with detailed ground-truth verification of street lighting across major cities in Central Java and DIY. Utilizing the Glimmer Imager for Urbanization (GIU) with 10-meter resolution, this research precisely identifies different urban street lamp types and evaluates their impact on energy consumption. As the demand for public street lighting grows with urban expansion, there is a pressing need for efficient energy management to sustain urban development and reduce environmental footprints. This study focuses on Semarang, Yogyakarta, and Solo, aiming to assess energy efficiency by examining how different street lighting affects energy usage across various road network types. By employing pan sharpening techniques to enhance image resolution and zonal statistics for in-depth analysis, the research finds significant correlations, especially in the red spectral band. This correlation suggests the potential of using SDGSAT-1 data to estimate streetlight energy consumption where direct measurements are unavailable. The findings also reveal significant variations in energy consumption across different road types, attributed to varying traffic and lighting needs. By highlighting these disparities, the study underscores the potential of transitioning to LED lighting, which can reduce energy consumption by up to 69%. This research not only demonstrates the capabilities of satellite imagery in urban energy management but also offers practical insights for cities looking to improve lighting efficiency, reduce costs, and promote sustainability in urban planning.

Abstract

The increasing urbanization and expansion of built-up areas in Riau Province have led to significant changes in land use patterns and population distribution. This study analyzes urbanization patterns and built-up land distribution in 12 districts/cities for the years 2020 and projected 2030, utilizing GHSL-SMOD data and the ClockBoard zoning system. GHSL is used to identify urban centers, population density, and built-up area characteristics, while ClockBoard provides a uniform geometric zoning framework to facilitate spatial analysis.The results reveal varied urban growth patterns across regions. Pekanbaru and Dumai show high density and significant expansion, while Bengkalis, Rokan Hulu, and Indragiri Hilir demonstrate clustered and linear growth patterns. Some districts, such as Siak and Kepulauan Meranti, exhibit urban sprawl. The development of urban centers does not always correspond to administrative size but is influenced by zoning structure and land-use density. The integration of GHSL-SMOD with ClockBoard proves effective in mapping urbanization variations and provides a solid foundation for more accurate, structured, and sustainable regional development planning.
