Abstract

Digitalization has rapidly permeated various fields in today's era, with marketing being a prominent recipient of its transformative effects. The business landscape has witnessed a pronounced inclination towards ventures that are grounded in digital marketing. It captures the interest of diverse market segments, including both business entities and the general public. This research endeavors to examine the alignment of digital marketing practices with Islamic business ethics. Employing a qualitative research methodology with a descriptive analytical approach, this study gathered the data through a comprehensive review of relevant documentation. The study focuses on digital social marketing technologies employed on social media platforms and marketplaces as primary samples. Findings reveal that the application of digital marketing in the Indonesian context falls short of complete compliance with Sharia principles. Despite this, certain marketing processes do exhibit adherence to aspects of Islamic business ethics. Notably, emphasis within this context tends to be more pronounced in elements related to products and promotional media. [ABSTRACT FROM AUTHOR]

Abstract

The exploration of oil palm empty fruit bunch (OPEFB) fiber as a construction material, especially in geotextile applications, is a growing area of interest. However, OPEFB fibers degrade rapidly, particularly in soil conditions, due to their natural composition. This study investigates the application of an alkaline solution, sodium hydroxide (NaOH), for enhancing the fiber strength and durability. OPEFB fibers, sourced from a palm oil mill in the Tanah Bumbu Regency, were treated via immersion in a 1N NaOH solution for 90 min. Subsequently, these treated fibers were embedded in soft soil and cured for 1, 7, 14, and 28 d under both open and closed conditions (that is, covered with plastic wrap). Tensile strength was assessed using specialized equipment designed for this purpose. Additionally, the fibers were blended with soil at a percentage of 7% based on dry weight, and compacted with 10% water content and a dry volume weight of 16 kN/m3. These samples were then tested for compressive strength, revealing a substantial improvement in the average tensile strength of fibers treated with NaOH at 288.22 MPa, which is 2.77 times greater than untreated fibers. Furthermore, the treated fibers exhibited enhanced durability, with tensile strength ranging between 160.2-179.58 Mpa and 184.11-22.2 MPa under closed and open conditions, respectively. Additionally, the compressive strength of the soil with treated fibers exceeded that of the soil with untreated fibers. Microscopic analysis revealed that the morphology of the treated fiber was denser and free of surface impurities, contributing to its improved performance. [ABSTRACT FROM AUTHOR]

26. STUDI JUMLAH PENYEBARAN KENDARAAN SETELAH PENGOPERASIAN FLY OVER PADA PERSIMPANGAN JL. A. H. NASUTION DENGAN JL. JAMIN GINTING.

Author

Ridha, Muhammad Abdhi

Abstract

Congestion is a common problem in transportation. Congestion can be caused by several things, one of which is the continued increase in population and the increasing number of immigrants who settle. This also happens in the city of Medan, especially at the intersection of Jalan A.H. Nasution and Jamin Ginting road. This rapid growth causes the volume of traffic at this location to increase, resulting in frequent traffic jams during rush hour. Seeing these problems, the Medan City government decided to build a flyover at the intersection location as a solution to overcome traffic jams. Which started in July 2012 and was completed in January 2015 and inaugurated on February 28 2015. However, is this construction currently able to overcome the congestion that occurs at this intersection? Therefore, this research was conducted to determine the effect of the flyover operation on the number of vehicles distributed at the intersection. Based on the results of the survey and analysis carried out at the intersection of Jl A.H Nasution and Jl Jamin Ginting, the highest traffic volume values were obtained at the intersection of Jl A.H Nasution (1812 vehicles/hour) and the flyover from the direction of Jl A.H. Nasution (4017 kend/hour) which occurred on Monday. The highest capacity value was on Monday afternoon on Jl. The highest degree of saturation value was obtained on Monday afternoon on Jl Ngumban Surbakti (0.951). So based on the indicator values obtained, it shows that the construction of flyovers as an alternative to reduce traffic jams is considered quite effective in accordance with the 1997 MJKI regulations which state that the value Maximum Degree of Saturation for urban areas is >1. This is also proven by the small number of vehicles crossing the intersection and conversely the number of vehicles crossing the flyover above it is quite large. [ABSTRACT FROM AUTHOR]

37. Perancangan Sistem Informasi SiapKolaborasi Berbasis Web Menggunakan Metode Waterfall

Author

Ridha, Muhammad Rizhan Ridha and Sri Mulyati

Abstract

Perkembangan teknologi semakin hari semakin meningkat, hal itu juga mempengaruhi tingkat pendidikan dan prestasi didunia. Semua orang mulai berlomba-lomba dibidang akademik maupun non akademik. Banyaknya perlombaan yang masih diadakan secara konvensional, semuanya masih bersifat offline seperti pendaftaran maupun informasi lombanya. Berkembangnya jumlah pelajar atau mahasiswa membuat tidak seimbangnya partisipan lomba, terkadang masih ada perlombaan yang tidak memiliki banyak kuota untuk menampung calon peserta. Hal ini juga diakibatkan karena sedikitnya perlombaan di daerah tersebut dan kurangnya informasi tentang perlombaan didaerah lain. Adanya mahasiswa yang hendak mengikuti perlombaan namun tidak memiliki tim pun banyak ditemukan karena kurangnya informasi maupun teman tim. Oleh karena itu, dengan adanya sistem ini diharapkan dapat menyelesaikan permasalahan diatas serta dapat memberikan informasi perlombaan maupun mencari anggota timnya sendiri melalui sistem informasi SiapKolaborasi ini.

38. Proposed Improvement of New Electrical Connection Business Process (Case Study of New Electricity Connection of PT PLN (Persero) Medium Voltage Customers)

Author

Ridha, Muhammad and Rosalendro Eddy Nugroho

Abstract

Based on the provisions of the Regional PLN for Java Madura Bali in 2021, the speed of new connection service days for medium voltage (20KV) customers is carried out a maximum of 100 working days. From the data on connecting new electricity customers at PLN UP3 North Banten from 2017 to 2020 there are 52 customers that exceed 100 days. This delay requires PLN to pay a fine to the customer, resulting in a loss. In this research, business processes are improved for new electricity connections so that problems do not occur again. This research was conducted with qualitative methods and data collection was carried out by direct interviews. By using value stream mapping, an analysis of the ongoing business processes is carried out so that nonvalue added activities can be eliminated and lead times can be reduced. The results of the future stream mapping show that the biggest delay in business processes comes from the licensing process and material preparation, so business processes are improved by changing the flow and simplifying activities. From the results of business process improvements, the lead time decreased by 40% so that from the previous 100 working days to 60 working days. In addition, there was an increase in the value-added ratio to 95% from the previous 76%

Abstract

Palm Kernel Shell (PKS) is a by-product of the palm oil processing industry that is typically located in areas with very soft soil, particularly in South Kalimantan. It has been extensively studied as a replacement for concrete granular material. Hence, research into the potential use of PKS as a supplement to stabilize soft clay is required. This study aimed to investigate the California Bearing Ratio (CBR) and unconfined compressive strength (UCS) of compacted soft clay mixed with PKS. The clay was taken from a location around Banjarmasin. The sizes of PKS were 4.75mm (i.e. sieve No. 4) and 2mm (i.e. sieve No. 10) for CBR and UCS tests, respectively. Based on the dry mass, the clays was mixed with a PKS content of 2.5%, 5%, 10%, 15%, and 20%. The CBR and UCS tests were performed to the compacted specimens. The presence of PKS resulted made it easy in compacting the soft soil and increasing the CBR and UCS of the mixtures. The maximum CBR and UCS were obtained at the highest density (i.e. a PKS content of 2.5%). The values increased 1.5 and 3 times higher for CBR and UCS, respectively, as compared to the soil without PKS. [ABSTRACT FROM AUTHOR]
