Abstract

Kelurahan Tanah Sereal Jakarta Barat sebagai salah satu wilayah perkotaan yang padat penduduk, memiliki potensi besar dalam sektor Usaha Mikro Kecil Menengah (UMKM). Salah satu bidang yang berpotensi berkembang pesat adalah usaha kuliner. Pada saat ini, Kelurahan Tanah Sereal belum memiliki sistem yang mampu memberikan informasi yang ditampilkan secara spasial mengenai pesebaran lokasi UMKM. Hal ini berakibat pertumbuhan bisnis kuliner seringkali terhambat karena kurangnya aksesibilitas informasi terkait sebaran usaha dan preferensi konsumen. Untuk mengatasi hambatan ini, penggunaan Sistem Informasi Geografis (SIG) dianggap sebagai solusi yang nantinya dapat memberikan informasi yang dapat dijadikan bahan pertimbangan yang tepat dalam menentukan kebijakan yang berkaitan dengan pertumbuhan UMKM di Kelurahan Tanah Sereal, fokus utamanya adalah membangun alat yang dapat membantu pemerintah setempat, pelaku bisnis, dan masyarakat dalam mengambil keputusan yang lebih baik terkait pengembangan UMKM seperti pengadaan pelatihan usaha, pemberian modal usaha, pelacakan tren konsumen dan pemahaman mendalam tentang dinamika pasar lokal. Pendekatan ini didasarkan pada Upaya meningkatkan keterlibatan Masyarakat dalam pengelolaan informasi yang relevan untuk perkembangan ekonomi lokal. Dalam kegiatan pengabdian kepada Masyarakat (PKM), tim akan mengembangkan sebuah Sistem Informasi Geografis (SIG) berbasis web untuk Kelurahan Tanah Sereal yang dapat memfasilitasi pemetaan penyebaran UMKM Kuliner dan memberikan akses informasi kepada masyarakat setempat yang berencana membangun bisnis UMKM kuliner atau mencari informasi tempat kuliner diwilayah Tanah Sereal Jakarta Barat.

Abstract

Business development in the era of the 21st century has grown very rapidly and has undergone a continuous metamorphosis. Every business actor in every business category is required to be sensitive to any changes that occur and place an orientation to customer satisfaction as the main goal. Supply Chain Management is a mechanism that connects all parties concerned and the activities involved in converting raw materials into finished goods. The importance of the role of all parties from suppliers, manufacturers, distributors, retailers to customers in creating cheap, quality and fast products is what gave birth to a new concept, namely supply chain management.

Abstract

 Correlated Color Temperature/CCT from artificial lighting in casual dining area at cafés is used to guide visitors visual perception through the interior atmosphere and dish display when served. Its visual impact triggers a non-visual response in the form of the visitors perception to rise appetite. This research aims to see the strength of causal relationship between perception of the dish display and the appetite for dining. A descriptive approach is used through questionnaire to examine the magnitude of this relationship using simple linear regression. The results show that the clarity of the dish display impact strongly on visitors perception on dish display (R Square 87.81%). Then, perception on dish display gives strong impact on appetite (R Square 87%). This research concludes that neutral CCT preferences give higher impact on dining appetite since the perception on the dish display has previously evaluated positive

Abstract

Plagiarism encompasses the act of appropriating high-quality user-generated content as if it were one's own intellectual property. Image plagiarism can be conceptualized as a broader category that encompasses the challenges of detecting copied images. Identifying instances of plagiarism is of paramount importance not only for graphic designers, professional photographers, and bloggers but also for publishing entities and legal practitioners seeking to uncover unauthorized reproductions of their creations. In addressing this issue, the implementation of blockchain technology presents a viable solution. Fundamentally more than just a collection of interconnected blocks, blockchain is characterized by the systematic recording of digital signatures or hashes of each block. Blockchain is essentially more than just a collection of interconnected blocks; it is characterized by the systematic recording of a digital signature or hash of each block. To generate the hash, cryptographic methods can be applied. This study aims to develop a web-based application that is adept at detecting image plagiarism through the application of blockchain technology. Images submitted by users will undergo plagiarism detection by an application that uses blockchain methodology. This study applies the DCT method to extract features from images, then uses the AES-128 and SHA-1 methods to generate blockchain. The results of this study are in the form of a website that can be used to detect image plagiarism. From the results of the tests carried out, it was obtained that the combination of the DCT, AES-128 and SHA-1 methods can detect image plagiarism with an accuracy of 100%. This means that the combination of these methods can be applied to carry out the process of detecting image plagiarism with a very high level of accuracy.

Abstract

PT Batam Bangun Prathama is a company engaged in the distribution of building and construction materials that imports building and construction materials such as iron tiles, angle iron, and others in Riau Islands. With 25 years of experience, PT Batam Bangun Prathama has been trusted by the Riau Islands community as a distributor of complete building and construction materials so that product standards cannot be doubted. At this time the problem that is being faced by the company when conducting the initial survey is that there are often cases where there is an imbalance between supply and demand for goods. The large number of buyers and the diversity of tastes in the goods they have makes it difficult for PT Batam Bangun Prathama to predict the best-selling items so that it cannot anticipate running out of these items by providing more stock than before. To overcome this, a prediction system is needed for the sale of goods that are most requested by consumers. This prediction will be useful to make it easier for the building stock provider at PT Batam Bangun Prathama in planning the supply of goods and informing the company about the products most purchased by consumers. The results of this research are a tree of sales prediction decisions with the highest gain value, namely price, quality and warranty as factors that greatly affect the availability of goods.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas dan kontribusi pajak hotel, restoran, hiburan, dan parkir terhadap Pendapatan Asli Daerah (PAD) Kota Malang pada periode 2017–2020. Pajak daerah yang terkait dengan sektor pariwisata dipandang strategis karena mencerminkan aktivitas ekonomi masyarakat dan wisatawan, khususnya di kota yang mengandalkan sektor jasa dan pariwisata. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan strategi studi kasus, berdasarkan data sekunder dari Badan Pendapatan Daerah Kota Malang yang dilengkapi dengan dokumen pendukung dan wawancara. Efektivitas diukur melalui perbandingan realisasi terhadap target, sedangkan kontribusi dihitung dari perbandingan realisasi pajak terhadap total PAD. Hasil penelitian menunjukkan bahwa efektivitas pemungutan pajak secara umum berada pada kategori efektif hingga sangat efektif pada periode 2017–2019, dengan pajak restoran yang konsisten menunjukkan kinerja tinggi. Namun, pandemi COVID-19 tahun 2020 menurunkan efektivitas pajak hotel dan hiburan secara signifikan. Meskipun demikian, kontribusi keempat jenis pajak tersebut terhadap PAD tetap sangat rendah, yaitu di bawah satu persen. Temuan ini menegaskan adanya kesenjangan antara pencapaian administratif dan kontribusi fiskal riil. Dibandingkan dengan Palangka Raya yang kontribusi pajak restorannya mencapai 8,61 persen, posisi Malang relatif lebih lemah karena PAD masih didominasi oleh transfer pusat. Kebaruan penelitian ini terletak pada analisis simultan efektivitas dan kontribusi dalam periode pandemi, yang jarang dikaji pada penelitian sebelumnya. Secara praktis, hasil penelitian memberikan rekomendasi kebijakan bagi Kota Malang, yaitu memperluas basis pajak melalui pendataan digital, memperkuat pengawasan dengan integrasi data transaksi daring, serta digitalisasi pelaporan dan pembayaran pajak. Strategi ini diharapkan dapat mengubah efektivitas administratif menjadi kontribusi nyata sekaligus memperkuat kemandirian fiskal daerah.

Abstract

BACKGROUND Adipose tissue is often overlooked in DNA testing due to misconceptions about its DNA content. However, its shock-absorbing qualities may be useful for high-pressure scenarios like bomb blasts. This study aimed to evaluate DNA quality and quantity in adipose tissue affected by blasts compared to that in unaffected tissue. METHODS 10 adipose tissue samples were taken from regions near and far from the blast, representing the blast-exposed and non-blast-exposed groups. The adipose tissue was stored at a low temperature for 5 days, after which an organic extraction method was applied. The purity of the DNA extract was assessed using a NanoDrop spectrophotometer, and its integrity was evaluated using 0.8% concentration gel electrophoresis at 60 V for 90 min. DNA typing was conducted using the GlobalFiler™ kit, and DNA quantity was determined with the Quantifiler™ Trio DNA Quantification kit. RESULTS Of 20 DNA extracts from adipose tissue, all samples demonstrated purity, integrity, and complete typing results. Adequate integrity was found in 90% of samples in both groups. A 50% incidence of allele shifting was observed at the D7S820 locus within the blast-exposed group. CONCLUSIONS DNA from blast-exposed adipose tissue exhibited no significant quality or quantity differences from non-blast-exposed tissue. This suggested adipose tissue’s potential as an alternative DNA source in a bomb explosion.
