Abstract

In this paper the number of  humans infected with cholera was controlled under the uncertainty in cholera model parameters. The aim of this research is to design an adaptive control so that the number of infected humans decreases. To achieve this goal, an adaptive controller was proposed to a deterministic model for the transmission of cholera involving five state variables (susceptible humans, infected humans, quarantined humans, recovered humans, and bacterial concentration) and one input control variable, i.e, the proportion of quarantined humans. A control law was designed such that the number of infected humans was decreased tracking the given reference function. The tracking error convergence were analyzed by employing the  Lyapunov theorem. The performance of the proposed controller was evaluated through numerical simulations. The results show that the adaptive controller designed to the model ensures the tracking error convergence such that the number of infected humans has declined.

Abstract

Public relations strategy in an era of increasingly rapid business growth, especially in the field of Hajj and Umrah travel agencies, which creates new problems in the form of mushrooming fraud cases. These cases raise concerns for prospective pilgrims about choosing and trusting Hajj and Umrah travel agencies. In practice, PT Freshnel Kreasindo Perkasa Yogyakarta carries out strategies to continue to stand strong amidst business competition and the rise of fraud cases so that the company's image and consumer trust can continue to be built and maintained. This research aims to find out how public relations strategies are in building the company image and trust of prospective Hajj and Umrah pilgrims at PT Freshnel Kreasindo Perkasa Yogyakarta. The theory used in this research is the PENCILS strategy theory developed by Rosady Ruslan. The research method used is descriptive qualitative. The results of this research show that PT Freshnel Kreasindo Perkasa implements the PENCILS strategy in building the image and trust of prospective Hajj and Umrah pilgrims well, while the PENCILS strategy is in the form of publications, events, news, community involvement, information or image, lobbying and negotiating, and social responsibility

Abstract

In real life, due to various measurement limitations, not all variables in the dengue fever epidemic model can be measured. Therefore, a tool is needed to estimate unmeasured variables with known related variables. One method for estimating variables in nonlinear systems is the extended Kalman filter (EKF). Next, using these estimated results, optimal control will be sought in the form of vaccination to reduce the number of infections. From the simulation results, it can be concluded that state estimation with EKF for the dengue fever model is good enough to estimate each variable with measurements that are disturbed by a random variable within the selected range of disturbance covariance. Then, it was found that the smaller the standard deviation of the disturbance, the smaller the optimal control required at the start. Thus, the greater the disruption, the greater the costs spent.

Abstract

Usaha Mikro, Kecil dan Menengah (UMKM) memiliki peranan penting dalam mendukung perekonomian desa, namun masih menghadapi hambatan, seperti kurangnya pemahaman tentang legalitas usaha, keterbatasan akses ke pasar, dan rendahnya penerapan teknologi digital. Di Desa Tegal Ombo, Kecamatan Way Bungur, Kabupaten Lampung Timur, banyak pelaku UMKM sudah memiliki Nomor Induk Berusaha (NIB), tetapi belum memahami fungsi dan manfaatnya secara menyeluruh. Selain itu, sistem pembayaran masih didominasi secara tunai, sementara kalangan muda lebih sering menggunakan media digital hanya untuk hiburan. Kegiatan pengabdian ini ditujukan untuk memperkuat UMKM melalui peningkatan legalitas usaha dan literasi keuangan digital, sekaligus melibatkan remaja desa dalam pemasaran produk dengan sistem affiliate marketing. Metode yang digunakan mencakup observasi, sosialisasi, pelatihan teknis, workshop, pendampingan, serta evaluasi kegiatan. Mitra sasaran terdiri dari 5 pelaku UMKM dan 10 remaja desa. Hasil menunjukkan adanya peningkatan pemahaman UMKM mengenai manfaat NIB dan pentingnya digitalisasi usaha meskipun perilaku masyarakat yang terbiasa dengan pembayaran tunai masih menjadi tantangan. Secara umum, program ini telah berkontribusi dalam peningkatan literasi digital, pemahaman legalitas usaha, serta keterampilan pemasaran digital sebagai langkah awal transformasi ekonomi desa menuju arah yang lebih inklusif dan berkelanjutan.

Abstract

Jurnal ini bertujuan untuk mengetahui ke-efektifitas-an Undang-Undang ITE atas terjadinya transformasi digital yang menjadi ancaman cybercrime di Indonesia. Banyak hal buruk dan tidak di inginkan terjadi melalui teknologi informasi. Sebab itu pemerintah merasa bahwa teknologi informasi tidak hanya perlu diperhatikan, tetapi juga perlu diatur dalam hukum melalui penerapan tindak pidana Undang-Undang ITE. Namun, hanya sedikit pasal yang mengatur demi terciptanya kelancaran perdagangan secara elektronik, seperti aturan-aturan yang harus dipatuhi bagi pelaku perdagangan elektronik. Isi dari UU ITE yang paling krusial adalah justru menekankan pada perbuatan-perbuatan yang tidak bersinggungan langsung dengan perdagangan elektronik, seperti pasal 27 ayat 1 dan 3, pasal 28 ayat 2, dan pasal 29 yang cenderung menekankan masalah sosial seperti asusila, perjudian, penghinaan, pemerasan, berita bohong dan menyesatkan, berita kebencian dan permusuhan, ancaman kekerasan dan menakut-nakuti.masalah tersebut jauh dari tujuan pasal 4 ayat 2 yang telah disebutkan diatas. Ada beberapa hal yang terlewatkan yang sebenarnya harus lebih difokuskan dalam UU ITE, antara lain masalah Spamming, baik untuk email spamming maupun masalah penjualan data pribadi oleh perbankan, asuransi, Virus, worm komputer (masih implisit di Pasal 33) terutama untuk pengembangan dan penyebarannya, dan jenis-jenis phising seperti typo pirates yang membuat tidak nyaman proses perdagangan elektronik. Masalah-masalah tersebut adalah juga krusial yang seharusnya secara eksplisit diatur dalam UU ITE, karena menyangkut juga demi terciptanya kelancaran transaksi elektronik khususnya perdagangan elektronik.
