DAMPAK DIGITALISASI PERTANIAN TERHADAP TINGKAT EKONOMI MASYARAKAT PETANI DI KECAMATAN ADILUWIH DAN GADINGREJO PRINGSEWU
Get PDFThe majority of Indonesia's population lives in rural areas so that agriculture is the main sector in the economy and the survival of rural communities where it is known that the national income generated from the agricultural sector is more than 50%. To increase the effectiveness and efficiency of agricultural activities, the application of technology, especially digital-based ones, is very necessary because it has a significant impact on improving the economy of farming communities in particular, one of which is the digitalization of agriculture.Based on the results of descriptive statistical analysis, it is known that the application of agricultural digitization in terms of the use of applications used as online marketing media in Adiluwih and Gadingrejo sub-districts is still relatively low. The low use of this application is due to several factors that influence the use of agricultural applications, including farmer readiness factors, age factors, gender factors, education factors, extension factors, and income factors. Furthermore, this agricultural digitization has an impact on the economic level of the farming community, although it is still relatively low, this digitalization can increase farmers' income by 8.5%. This increase in income is obtained from the marketing of agricultural products through online media which is part of the digitalization tools in agriculture. This is an opportunity so that the application of digitalization and information technology in agriculture can be developed optimally in order to increase the economic growth of rural communities

Determining the Distribution Route Using the Clustered Generalised Vehicle Routing Problem Model and Dijkstra's Algorithm
Get PDFDistributions and logistics processes are the essential element activities integral to the industrial sector, one of them is the distribution of LPG 3 kg. The most common issue that occurs in the distribution process is determining the vehicle routes which are often called Vehicle Routing Problems. PT Amalia Yusri is one of the distributor agents of LPG 3 kg in Banda Aceh and also had the same issue to determine the distribution routes. The Clustered Generalized Vehicle Routing Problem model is used to determine the optimal distribution route on the vertex destinations that have been grouped. Based on the number of requests and vehicle capacity, the grouping and formation of clusters are divided into two days and split into five groups. The first day consists of group 1 and group 2; while on the second day are group 3, group 4, and group 5. The method that is used to optimise distribution distance is Dijkstra Algorithm. From the application of the CGVRP model and Dijkstra Algorithm obtained a total distance for group 1 is 25.582 m, group 2 is 24.650 m, group 3 is 39.350 m, group 4 is 27.500 m, and group 5 is 38.500 m
FORMULASI NANOEKAPSULASI EKSTRAK DAUN KELOR (Moringa oleifera) /KITOSAN-NATRIUM TRIPOLIPOSFAT (NaTPP)
Get PDFMoringa (Moringa oliefera) contains several antioxidant compounds such as quercetin and chlorogenic acid. However, antioxidants have weaknesses, namely that they are easily damaged by exposure to oxygen, light, high temperatures, and drying. One way to maintain and increase the stability of antioxidants is by encapsulation. The purpose of this study was to determine the optimum formulation of quercetin nanoencapsulation of moringa leaf extract using chitosan and sodium tripolyphosphate (Na-TPP) using the ultrasonication method. Moringa leaf extract was obtained by repeated ultrasonication 1x 15, 3x15, and 5x15 minutes, frequency 24 kHz, and using alcohol 96%. The encapsulation process was carried out with three variable ratios of the amount of chitosan: Na-TPP added to 10 mL of Moringa leaf extract solution (F0), namely 5:1 (F1), 2:1 (F2), and 1:1 (F3). Test results for flavonoids as quercetin using a UV-Vis spectrophotometer showed that the Quercetin content in Moringa leaf extract ultrasonicated 5x15 minutes was 12.146%, the characterization of the Particle Size Analyzer (PSA) showed encapsulated particle sizes of 170.3 and 209.7 nm with polydisperse index <0 .5, the antioxidant activity test using the DPPH method showed that F0 was 61.4% and F2 had the highest antioxidant activity, namely 81.2%. Analysis of the morphology of nanoparticles using Scanning Electron Microscopy (SEM) showed that the particles were spherically distributed evenly. Nanoencapsulation of Moringa leaf extract has resulted and an increase in the antioxidant activity of Moringa leaf extract after encapsulation using Chitosan-NaTPP, from 61.4% to 81.2% (F2)
