Judul: An Affective Design of E-commerce Website Content for SMEs Product Marketing Using Kansei Engineering Approach
Abstrak: Nowadays, e-commerce is known to the public as an excellent tool for online product promotion. Retailers and manufacturers can easily share their product information. E-commerce websites to promote Small and Medium Enterprises (SMEs) products have developed in Indonesia, for example, I-Shop NTB, Rumah Belanja Denpasar, Sadewa Market, and Banyuwangi Mall. The number of e-commerce that offers similar products makes customers smarter to choose e-commerce that will use. This makes the affective quality of e-commerce more crucial than ever. Customers will prefer e-commerce that can satisfy them emotionally rather than function very well. Kansei Engineering (KE) is a method for translating the feelings of e-commerce users into e-commerce design elements. This study aims to produce a formulation of e-commerce website content design that can meet the affective needs of e-commerce users with a case study of Ponorogo SME products. The results of this study show that the e-commerce website design process system of SMEs consists of three stakeholders, namely marketing officers, product developers, and website designers. The marketing officer is responsible for determining the design concept based on market needs. The product developer is responsible for determining the design elements and model formulations for each concept. Website designers tasked with designing e-commerce prototypes and predicting market acceptance. The results of the Kansei word extraction from e-commerce users using TF-IDF and PCA produced two concept designs namely "Sophisticated" and "Affordable". Identification of design elements produces 16 relevant design elements: color and background style, page style, menu category style, dominant color, dominant item, text font size and color, picture size, product presentation feature, seller and product information, product display, visual techniques, product page presentation mode and product list information page format. But there are only ten elements analyzed using QTT-1 including six website design elements and 4 product presentation design elements. The QTT-1 analysis results were a "Sophisticated" website and "Affordable" product presentation as the best design concept for the Ponorogo SMEs e-commerce website. Where both of these designsare distinguished by looking at the background style (X2), the dominant color of the page (X5), the size of the image (X9) and the product presentation feature (X10). These four elements are used to predict customer acceptance of the I-Shop Ponorogo affective design using Fisher's exact test to determine the effect of design elements and user purchase decisions. Evaluation of the results of customer purchase decisions shows that two design elements influence customer purchase decisions, namely the dominant color page and image size.

Judul: Evaluation of PT XYZ’s, a Plantation Research Company, E- Commerce Information System Success
Abstrak: PT XYZ, a company engaged in plantation research, has implemented e- commerce which has great potential in supporting its digital marketing success. However, there are problems that are thought to have an impact on the low percentage of the contribution of e-commerce sales transactions to non-e-commerce transactions. This research was conducted to examine more deeply the conditions of PT XYZ's. This research aimed to measure the level of success, analyze the factors that influence success, so that in the end it can provide recommendations to increase PT XYZ's e-commerce success. This research was conducted to evaluate e-commerce success using the IS success model so it could found the impact of the variables in the model on e- commerce success. For this reason, this study adopted the theoretical framework of DeLone and McLean (2003) as a method for assessing the success of implementing PT XYZ's e-commerce information system. This research was conducted by collecting PT XYZ e-commerce user assessment data as research respondents and using an instrument in the form of a questionnaire that distributed online. The research was conducted from August 2022 to February 2023 and involved 166 respondents who were PT XYZ's e-commerce users. Based on the results of measuring the success of e-commerce, it was considered by user that the e-commerce success was in good category. PT XYZ's e-commerce technical success, represented by the System Quality variable, was considered very good with an average score of 4,01 based on the results of the analysis using the oneway ANOVA method. Assessment of semantic success (represented by the Information Quality variable) and system effectiveness success (represented by the variables of Usage, User Satisfaction, and Net Benefit) were considered good, with the average results respectively 3,83 and 3,54. Meanwhile, Service Success as represented by the Service Quality variable was considered good, but had the lowest average score of 3,50. The estimation results of the SEM-PLS model show that the System Quality variable has no significant effect on Usage, but has a significant effect on User Satisfaction. Information Quality Variable significantly affects Use and User Satisfaction. Service Quality Variables significantly influence the Use and Quality of Service. The User Satisfaction Variable significantly affects the Net Benefit, but the Usage variable does not significantly affect the Net Benefit. Based on these results, the factors that significantly influence PT XYZ's e-commerce success are User Satisfaction which is influenced by the Quality of Systems, Information, and Services.

Judul: Molecular Systematics of Tree Frog Nyctimystes infrafrenatus infrafrenatus (Tyler 1971) from Papua and Moluccas
Abstrak: Nyctimystes infrafrenatus memiliki permasalahan taksonomi yang cukup kompleks. Spesies ini pertama kali dideskripsikan dengan nama Hyla infrafrenata. Kemudian berdasarkan karakter morfologinya spesies ini dikelompokkan ke dalam genus Litoria dan lebih dikenal dengan nama Litoria infrafrenata namun hasil analisis filogenetika molekuler menempatkan spesies ini pada clade Nyctimystes. Nyctimystes infrafrenatus memiliki dua subspesies yaitu Nyctimystes infrafrenatus infrafrenatus dan Nyctimystes infrafrenatus militarius. Subspesies N. infrafrenatus militarius memiliki distribusi yang terbatas pada Kepulauan Bismarck, Papua New Guinea sedangkan N. infrafrenatus infrafrenatus distribusinya mencakup wilayah utara Sulawesi, Kepulauan Maluku, Pulau Timor, Papua, Australia hingga Kepulauan Solomon. Distribusi yang luas tersebut dapat memunculkan fenomena kriptik spesies. Populasi spesies ini di wilayah Indonesia mewakili dua subregion zoogeografi yang memiliki sejarah pembentukan wilayah yang berbeda yaitu Papua dan Wallacea. Lautan merupakan barrier utama distribusi hewan amfibi karena rendahnya toleransi amfibi terhadap salinitas. Hal ini menimbulkan kemungkinan bahwa N. infrafrenatus infrafrenatus populasi Maluku berbeda dari populasi Papua. Penelitian sebelumnya tentang morfometrik menunjukkan adanya perbedaan ukuran kaki belakang individu betina antara populasi N. infrafrenatus infrafrenatus Papua dan Maluku. Temuan tersebut perlu ditelusuri lebih lanjut dengan pendekatan molekuler. Penelitian ini bertujuan untuk mengevaluasi sistematika N. infrafrenatus infrafrenatus dari Papua dan Maluku. Penanda genetik yang digunakan pada analisis molekuler adalah sekuens gen 16S rRNA. Hasil pensejajaran sekuens ini digunakan untuk rekonstruksi pohon filogenetik, mengestimasi waktu divergensi dan jarak genetik kedua populasi tersebut. Hasil rekonstruksi pohon filogenetik menempatkan semua sampel N. infrafrenatus infrafrenatus pada satu clade monofiletik (MLBS 99%, BPP= 100%). Clade ini kemudian membentuk dua subclade yaitu subclade A yang terdiri atas sampel-sampel dari Papua dan Australia (subclade Papua) serta subclade B yang terdiri dari sampel-sampel Halmahera dan Ternate (subclade Maluku). Hasil estimasi waktu divergensi menunjukkan bahwa kedua subclade tersebut mulai terpisah sejak 6.03 juta tahun lalu (jtl). Jarak genetik antara kedua subclade (2,3,- 4,2%) berada pada threshold beda spesies 3%. Sampel Australia dan populasi Papua mewakili “the true” N. infrafrenatus sedangkan populasi Maluku dengan jarak genetik 3,9-4,2% dengan sampel Australia terindikasi kuat secara genetik merupakan spesies yang berbeda. Berdasarkan artikel 23 ICZN, nama Nyctimystes tennuigranulatus dapat digunakan terutama untuk populasi Maluku bagian utara. Analisis lebih lanjut secara morfologi, akustik dan ekologi yang melibatkan sampel dari Ambon diperlukan untuk menentukan status taksonomi populasi Maluku secara menyeluruh.
