The e-commerce industry which is developing significantly is always required to be able to adapt well to technological developments where information systems/information technologies (IS/IT) strategic planning must be further developed to support the company's business processes. In this research, the authors focus on analyzing how the information systems strategic planning is currently underway at an e-commerce company. The author uses the ward and peppard framework to analyze the business environment and IS/IT environment internally and externally. Many methods have been developed within the framework such as strengths, weaknesses, opportunities and threats (SWOT) analysis which focus on exposure the company's internal and external conditions, McFarlan strategic grid focus on assessing the overall contribution of IS/IT, and its impact on business success, from both a strategic, and operational perspective, value chain focus on optimizing technology, and business applications, political, economic, social, and technological (PEST) analysis focus on considerations of legal, political, economic, social, and technological developments, critical success factor (CSF) analysis focus on product quality priorities, customer service, product prices, company resources, and technology used. The results of the analysis of these methods are the results of this study, namely the results of portfolio application recommendations for the next four years which can be used as a reference for companies to develop their business strategic planning systems.

This article presents a novel type of mobile phone application approach using the wireless fidelity (WiFi) system. Which is capable of facilitating the public transport user and its drivers efficiently. The application support passengers when there are scenarios where commuters face problems while using public transport. If users get bus information beforehand, such as bus location and arrival time, the number of passengers in the public transportation system. This application has been developed for the Android operating system. The application includes bus details like real-time bus location, bus arrival time, bus routes, bus stops, bus numbers, and so on. After the trip is booked, users' devices allow real-time geolocation to be shared in the application, helping the bus driver decide to stop at one stop or move to another when there are no users.

Coronary heart is the highest cause of death in Indonesia reaching 26%. Therefore, to prevent the high mortality rate of coronary heart disease (CHD), early detection of CHD can be carried out. One way is to examine the electrocardiogram/electrocardiograph (ECG) recording. ECG hardware has been made in previous studies to record ECG signals. ECG research is an important study because it can detect cardiovascular disease. Cardiovascular diseases can be classified as arrhythmic diseases. Arrhythmia is a disorder that occurs in the heart rhythm. The method used to recognize and classify ECG signal patterns is the R-R interval (RRI) method. In this study, the ECG signal is classified as normal and abnormal. Abnormal means that a person has a heart rhythm disorder. The classification method used is random forest. The advantage of the random forest classifier is that it can handle noise and missing values and can handle large amounts of data. The accuracy of the ECG signal classification using the Random forest method is 96%. The contribution of this research is that early detection of heart rhythm disorders using an ECG can be monitored through the smart healthcare web.

Embung Batur Agung is a source of irrigation for residents around Embung. Depreciation of water in the reservoir occurs due to leakage from the geomembrane layer of the Embung Batur Agung. This study aims to determine the direction of leakage from the reservoir so that appropriate treatment can be carried out. This research was done using hydrogeological analysis and electrical resistivity tomography (ERT) geoelectrical measurements. ERT Geoelectrical measurement uses a dipole-dipole configuration with a spacing of 5 m and 10 m and a line length of 100 m. There are 2 lines in the southwest and southeast of the reservoir. The results of geohydrology analysis, it was found that the aquifer system around the reservoir included in the Gunungsewu aquifer system, and the dynamics of surface groundwater are controlled by faults and fractures. The results of the ERT geoelectrical measurement, there is a low anomaly which can indicate a reservoir leak at 50-60 m on line 1 which is in the southwest of the reservoir. This low anomaly has a vertical pattern as well as there is a fracture which is the cause of the reservoir leak. These low anomaly values range from 4-30 Ωm which can be interpreted as the presence of water that has conductive properties. The results of this study are expected to be used by the local government to handle the leakage of the reservoir.

The study aims to compare the physical characteristics (water holding capacity and cooking loss) and chemical characteristics (moisture, protein, fat, ash, carbohydrate content, and total calories) of Chitofudregs nugget with commercial nuggets. Four categories of nuggets which are Fiesta, So Good, Nugget Curah, and Chitofudregs nugget (FT, SG, NC, and Chitofudregs) were determined as treatments in this study with 5 repetitions for each category. The experimental method of this research was a randomized design complete (RDC). Physically, Chitofudregs had the highest water-holding capacity and the lowest cooking loss among all commercial nuggets (p<0.05) so there were not many nutrient losses during the processing. Chemically, Chitofudregs contained higher water content than one of the commercial-NC nuggets while the protein and ash content was lower than the two types of commercial nuggets (FT and SG) with carbohydrate content which was also lower than the NC commercial nuggets (p<0.05). The fat content and total calories of chitofudreg were the lowest among all commercial nuggets (p<0.05). Chitofudregs are combination nuggets whose physical quality is as good as commercial nuggets with specific chemical characteristics and has potency as a diet product because it is low in fat and calories.

Artificial intelligence can help classify plants to make identification easier for everyone. This technology can be used to classify mangrove trees. The degradation of mangrove forests has resulted in a 20% loss of biodiversity, an 80% loss of microbial decomposers, reduced C-organic soil, and fish spawning grounds, resulting in estimated losses in the ecological and economic fields for up to IDR 39 billion. The identification of different mangrove species is the first step in ensuring the preservation of these forests. Therefore, this research aimed to develop algorithms and a convolutional neural network (CNN) architecture to classify mangrove tree species with the highest possible accuracy using Python software. The architecture selection for this model includes a batch size of 32, an input image size of 128x128 pixels, four classes, four convolution layers, four rectified linear unit (ReLU) layers, 2x2 max-pooling, and two fully connected layers (FCL). The finding showed that the resulting accuracy from the test was 97.50%, while the validation test was 81.25%, applied to four types of mangrove leaves, including Avicenia marina, Avicenia officialis, Rizophora apiculata, and Soneratia caseolaris.

Saccharum edule Hassk (Terubuk) is a plant of the Poaceae family that after consuming its flowers as vegetables, Saccharum edule Hassk waste in the form of leaves and stems can be used as alternative animal feed. Improving the nutrition of crushed waste as an alternative feed can be done through ensilage using several mixed ingredients that can maximize the fermentation process. The study aimed to analyze the effect of differences in the ratio of starter microbial with a mixture of silage, such as molasses and rice bran, on the quality of the Saccharum edule Hassk waste silage. The research was conducted using leaf and stem material using the anaerobic fermentation method. The ratio of microbes, molasses, and rice bran used was 0.00067%:2%:4% (S1), 0.0008%:3%:6% (S2), and 0.001%:4%:8% (S3). The fermentation time was 14, 21, and 28 days. The results obtained showed that pH <4 was achieved by S1, S2, and S3, at 21 and 28 days of fermentation. Fleigh value (NF) of S1 and S2 at 21 days of fermentation was 72.47% while in S3 it was 72.20%. The NF at 28 days of fermentation was 85.53% in S1, and 85. 67% in S2 and S3. The highest protein content is in S2 at 10.37 ± 0.69% (p>0.05) in a fermentation time of 21 days.
