Abstract

This study aims to determine the effect of unemployment and ZIS funds' distribution on South Kalimantan poverty. This is a quantitative study with secondary data in the form of time series data for 2012-2021 obtained from the Central Statistics Agency (BPS) and the National Amil Zakat Agency (BAZNAS). Based on the results of statistical analysis using the Eviews 9 application, it is assumed that all the requirements in the classical assumptions are met so that multiple linear regression analysis can be carried out with t-test and f-test. The results of this study indicate that the unemployment rate and the distribution of ZIS funds simultaneously have a significant effect on the poverty level in South Kalimantan. However, partially, only the unemployment rate has a considerable effect. In contrast, the distribution of ZIS funds does not have a substantial impact because consumptive, not productive; programs still dominate the distribution pattern of ZIS funds. Therefore, this study resulted in a recommendation to increase the distribution of ZIS funds productively to impact poverty alleviation in South Kalimantan significantly.

Abstract

Penelitian ini menganalisis sungai kapuas sebagai sarana transportasi air untuk angkutan barang di Provinsi Kalimantan Barat menggunakan metode location quontient, menganalisa kemampuan angkutan barang yang menggunakan kapal bandong dan kapal tongkang, meramalkan jumlah kapal motor dan kapal barang 5 tahun kedepan dengan metode trend liniear, kemudian menganalisis potensi sungai kapuas untuk angkutan barang. Dari hasil analisa didapat 5 kabupaten yang sektor pertanian dan pertambangannya berpotensi, 3 kabupaten yang hanya memiliki satu sektor yang berpotensi, 2 kabupaten yang kedua sektornya tidak berpotensi, didapat 5 kabupaten penghasil kelapa sawit terbesar, 3 kabupaten penghasil karet terbesar, pada sektor pertambangan di dapat 3 sumber daya mineral yang potensi angkutannya besar yaitu antimoni dan cinnabar dan batubara. Untuk peramalan kapal motor dan kapal barang didapat bahwa 5 tahun kedepan jumlah kapal mengalami penurunan. Sungai kapuas sangat berpotensi di jadikan sarana transportasi air karena keadaan jalan darat hanya mampu menahan beban sebesar 8 ton, jika menggunakan jalan darat dengan angkutan yang besar secara terus menerus maka jalan darat akan mudah rusak dan biaya pemeliharaan jalan akan lebih besar. Dibandingkan dengan menggunakan transportasi air ini lebih hemat biaya, muatan yang di angkut lebih besar, kendalanya di  muara sungai kapuas karena harus menunggu air pasang agar bisa dilewati.Kata kunci : Angkutan Barang, Transportasi Air, Potensi Sungai.
KOMPARASI HUKUM INDONESIA DAN HUKUM ISLAM TERHADAP PERLINDUNGAN DATA PRIBADI DALAM TRANSAKSI EKONOMI SYARIAH DIGITAL Ilham; Muhammad Ramadhani; Muhammad said ridho; Yusuf Afrenoldi Todi; Rifqi Hidayat; Mahipal

Abstract

Transaksi ekonomi syariah digital yang berkembang melalui berbagai platform seperti fintech syariah dan e-commerce syariah memunculkan tantangan baru terhadap perlindungan data pribadi. Di tengah meningkatnya penggunaan layanan keuangan berbasis teknologi, perlindungan privasi dan data individu menjadi isu yang sangat penting dalam memastikan keadilan, keamanan, dan keabsahan transaksi syariah. Penelitian ini bertujuan untuk menganalisis secara komparatif bagaimana hukum positif Indonesia—khususnya Undang-Undang Nomor 27 Tahun 2022 tentang Perlindungan Data Pribadi—dan prinsip-prinsip hukum Islam mengatur dan melindungi data pribadi dalam transaksi ekonomi syariah digital. Dengan pendekatan yuridis-normatif dan kajian komparatif, penelitian ini mengidentifikasi titik temu dan perbedaan kedua sistem hukum tersebut, serta mengkaji tanggung jawab hukum para pihak atas pelanggaran data. Hasil kajian menunjukkan bahwa meskipun pendekatannya berbeda, baik hukum nasional maupun hukum Islam sama-sama menekankan pentingnya perlindungan atas hak privasi individu sebagai bagian dari perlindungan hukum yang menyeluruh. Penelitian ini juga merekomendasikan sinergi antara regulasi nasional dan prinsip syariah dalam membentuk ekosistem digital yang adil dan bertanggung jawab.

Abstract

Titik Awal Kopitiam Jatinangor is an MSME in the culinary sector that has not yet fully optimized its digital marketing strategy. The main issues faced include low brand awareness and brand loyalty due to an unstructured and impersonal approach to social media and membership programs. This project aims to improve brand awareness and brand loyalty through the optimization of social media (Instagram and TikTok) and the implementation of email marketing based on Customer Relationship Management (CRM). The methods used include rebranding, developing a content marketing strategy through content pillars and a content calendar, and customer segmentation for more relevant email campaigns. The project showed significant performance improvements: Instagram followers increased by 4.33%, reach grew by 223%, and impressions rose by 84%. TikTok recorded a 70.76% increase in followers, 7,615% in reach, 4,470% in views, and 119.44% in likes. Email marketing achieved an open rate of 36.8% and a delivery rate of 97.7%. The membership repeat purchase rate also increased from 17.18% to 22.39%. These results demonstrate that the integration of social media and CRM-based email marketing is effective in enhancing brand awareness and brand loyalty. This project also contributes theoretically to the development of digital marketing strategies for MSMEs, particularly in the coffee shop sector.

Abstract

The use of buck converters as DC step-down voltage regulators is increasingly important in various power electronics applications. However, the quality of the output voltage is often disturbed by the presence of ripple, which is influenced by variations in the duty cycle. This study aims to analyze the effect of duty cycle variations on the output voltage and ripple of a buck converter using MATLAB/Simulink simulation. The method used is quantitative simulation by varying the duty cycle from 10% to 90% in a buck converter circuit with fixed parameters: input voltage 30 V, switching frequency 40 kHz, inductor 176.25 μH, and capacitor 44.33 μF. The simulation results show that the output voltage is proportional to the duty cycle, increasing from 3.245 V at D=10% to 26.82 V at D=90%. The highest ripple occurred at D=40% with a value of 0.07 V, while the lowest ripple was at D=50% with a value of 0.0003 V. These findings indicate the existence of an optimal operating point where the system works most stably. This study provides practical guidance in designing efficient and stable buck converters for applications such as battery charging and renewable energy systems.
