Abstract:
Abstract Rice is consumed by most of the population in Indonesia. The generative phase, the final stage of rice growth cycle, produces raw grains that are processed into rice, forming the basis of rice production. To estimate rice paddy productivity in March 2023, vegetation indices such as the Normalized Difference Vegetation Index (NDVI) and the Optimized Soil-Adjusted Vegetation Index (OSAVI) are used. These indices are crucial as they correlate with rice paddy areas in the generative phase. Sentinel-2A imagery calculations have shown strong correlations, with NDVI at R = 0.61 and OSAVI at

Abstract:
The traditional visual rating system is labor-intensive, time-consuming, and prone to human error. Unmanned aerial vehicle (UAV) imagery-based vegetation indices (VI) have potential applications in high-throughput plant phenotyping. The study objective is to determine if UAV imagery provides accurate and consistent estimations of crop injury from herbicide application and its potential as an alternative to visual ratings.

Abstract:
Canopy reflectance sensors are a viable technology to optimize the fertilization management of crops. In this research, canopy reflectance was measured through a passive sensor to evaluate the effects of either crop features (N fertilization, soil mulching, appearance of red fruits, and cultivars) or sampling methods (sampling size, sensor position, and hour of sampling) on the reliability of vegetation indices (VIs). Sixteen VIs were derived, including seven simple wavelength reflectance ratios (NIR/R460, NIR/R510, NIR/R560, NIR/R610, NIR/R660, NIR/R710, NIR/R760), seven normalized indices (N

Abstract:
Heterogeneity exists in the vertical distribution of the biochemical components of crops. A leaf chlorophyll deficiency occurs in the bottom- and middle-layers of crops due to nitrogen stress and leaf senescence. Some studies used multi-angular remote sensing data for estimating the vertical distribution of the leaf chlorophyll content (LCC). However, these studies performed LCC inversion of different vertical layers using a fixed view zenith angle (VZA), but rarely considered the contribution of the components of the non-target layers to the spectral response.

Abstract:
Drought is one of the most devastating disasters and a serious constraint on agricultural development. The reflectance-based vegetation indices (VIs), such as Normalized Difference Vegetation Index (NDVI), have been widely used for drought monitoring, but there is a lag in the response of VIs to the changes of photosynthesis induced by drought. Solar-induced chlorophyll fluorescence (SIF) is closely related to photosynthesis of vegetation and can capture changes induced by drought timely.

Abstract:
The concluding chapter documents the transition of the country of Tsugaru from early modern Tokugawa society to the modern Meiji nation-state, through the experiences of the Hirata school kokugaku scholars residing in Hirosaki castle town. The chapter explores the significance of their efforts to identify their place of belonging from country to nation, and considers the legacy of their work and experiences. It discusses the legacy of the Hirata disciples in Hirosaki domain and Aomori prefecture and the lessons that can be learned from their experiences. The chapter also presents the document Namelist of Festival Participants (Shukusaiten yūshi meibo), which shows how Shinto priest Osari Nakaakira led annual festivals to venerate the Four Great Men of kokugaku some three decades after the Restoration, as well as the shōkonsai festival and the religious Separation of Shinto and Buddhism policy. Ultimately, it discusses Nakaakira's discussion on the effects of the kokugakusha's (Japan studies scholars) endeavours.

Abstract:
Remote sensing is crucial in agriculture for identifying pests and disease infestations in crops, reducing production and quality. Hyperspectral remote sensing sensors record reflectance in narrow bands of electromagnetic spectrum, including visible, near-infrared, and short wave infrared regions. Early detection of disease on cotton crops is crucial for timely control. This research uses an ASD FieldSpec4 spectroradiometer to capture spectral data from leaf samples, analyzing physical and biochemical changes in crops in a nondestructive way. Spectral vegetation indices (VI) are used to derive reflectance properties of vegetation, highlighting specific vegetation properties. Bacterial Blight infection on cotton crop is categorized in different grades. Vegetation indices, MCARI, TCARI, NPCI, OSAWI used to find the infection effects. SVM and Decision Tree classifier is used to find the results. SVM and Decision tree classifier gives training accuracy R2 as 91.66 and 92.85 and Mean Square Error 0.08 and 0.07 respectively. At Validation stage SVM and Decision Tree gives result R2 as 95.55 and 95.83 and Mean Squared Error 0.06 and 0.01 respectively.

Istraživački rad fokusira se na Camp Zagreb u Svetoj Nedelji, detaljno analizirajući strategije za produženje turističke sezone i privlačenje gostiju izvan tradicionalnih sezona. Kroz dubinski intervju s vlasnikom, gospodinom Krešimirom Dubrovićem, stječe se dublji uvid u perspektivu vlasnika te razmatra moguće strategije za unaprjeđenje poslovanja. Analiza trenutnog stanja otkriva da kamp ima povoljnu geografsku poziciju koja omogućava lakšu dostupnost gostima, posebno zbog blizine prometnica i zračne luke. Međutim, istovremeno se prepoznaje nedostatak jasne vizije i slabosti u marketinškoj strategiji, što može ograničiti daljnji razvoj i konkurentnost kampa.SWOT analizom identificirane su ključne snage, poput povoljne geografske pozicije i prihvatljivih cijena, ali i slabosti kao što su nedostatak jasne vizije i neadekvatna marketinška strategija. Prijedlozi za unapređenje fokusiraju se na jačanje marketinške strategije korištenjem društvenih mreža kao ključnog alata za komunikaciju s potencijalnim gostima. Također, ističe se potreba za implementacijom interaktivnih inicijativa poput eko tržnice i inicijative "Ostavi svoj trag", koje bi privukle goste kroz edukativne i ekološki osviještene aktivnosti.Ovaj istraživački rad ima potencijal pridonijeti održivom razvoju turizma i povećanju konkurentnosti destinacije izvan tradicionalnih sezona. Kroz implementaciju predloženih strategija, Camp Zagreb može postati privlačnija destinacija za širi spektar gostiju te doprinijeti razvoju lokalne zajednice.
