Abstract

ABSTRAKPenerapan teknologi Long Term Evolution (LTE) di Indonesia belum optimal dalam pengalokasian spektrum dikarenakan keterbatasan spektrum, untuk mengatasi masalah tersebut 3GPP mengeluarkan teknologi terbaru yaitu LTEAdvanced yang mendukung fitur carrier aggregation (CA) yang memberikan throughput yang lebih tinggi dengan penggunaan spektrum yang lebih efisien. Pada penelitian ini dilakukan perencanaan jaringan LTE-Advanced menggunakan metode inter-band CA dengan menggabungkan dua band frequency yang berbeda yaitu bandwith 5 MHz di band 5 (850 MHz) dan bandwidth 10 MHz di band 3 (1800 MHz). Untuk mendapatkan performansi yang maksimal perencanaan jaringan LTE dan LTE-A dikombinasikan dengan penggunaan skema Physical Cell Identity (PCI) dan Soft Frequency Reuse (SFR). Penggunaan PCI meningkatkan SINR sebesar 1 dB dan throughput meningkat sebesar 200 Kbps, sedangkan penggunaan skema SFR meningkatkan SINR sebesar 9 dB dan throughput meningkat sebesar 13 Mbps.Kata kunci: LTE-Advanced, PCI, SFR, Carrier Aggregation. ABSTRACTThe implementation of Long Term Evolution (LTE) technology in Indonesia has not been optimal due to spectrum limitations. To overcome the problem, 3GPP issued the latest technology, i.e. LTE-Advanced, to support the carrier aggregation (CA) feature that provides higher throughput with more efficient spectrum usage. In this study, LTE-Advanced network planning was performed using the inter-band CA method by combining two different band frequencies, namely 5 MHz bandwidth on Band 5 (850 MHz) and 10 MHz bandwidth on Band 3 (1800 MHz). In addition, to generate maximum performance, the LTE and LTEA networks planning was combined with the use of Physical Cell Identity (PCI) and Soft Frequency Reuse (SFR) schemes. The use of the PCI managed to increase SINR by 1 dB and throughput by 200 Kbps, while the use of SFR scheme managed to increase SINR by 9 dB and throughput by 13 Mbps.Keywords: LTE-Advanced, PCI, SFR, Carrier Aggregation.

Abstract

As digital technology based on the Internet of Things (IOT) develops, it should be able to increase banking access (inclusivity) for customers and attract the interest of potential customers. Banking digitalization is currently much more developed than just transaction features but also includes a savings account opening system. Bank Muamalat Indonesia is one of the sharia banks that participates in the development of digital technology by presenting a mobile banking application called MDIN or Muamalat Digital Islamic Network. Digitalization of sharia banking should provide convenience and attract the interest of potential customers, considering that the market share of sharia financial institutions in Indonesia is still low. This research aims to determine customer preferences for opening a savings account via MDIN. This research uses a qualitative research method with a case study approach. The objects of research include customer preferences in using MDIN digital banking. The subjects of this research are customers who open savings accounts through MDIN. The research results show that customer preferences in using MDIN as an option for opening a savings account are based on several factors such as social factors, ease of service, benefits and personal factors. Social and personal factors are the most dominant factors in customer’ decision making to open a savings account through MDIN digital banking.

Abstract

Universities should not only put pressure on, but also start to innovate to facilitate students, especially in terms of information and services that can help students complete their final assignments/thesis. Sometimes, students are confused with the stages of writing a thesis starting from submitting a title until the thesis is ready to be tested. Some of the problems found in the student environment related to the process of submitting the thesis are firstly the Standard Operating Procedure (SOP) for the student's thesis has not been systematically arranged, secondly the unclear requirements for thesis submission, thirdly the absence of teaching aids or tools that make it easier for students to obtain information independently, the four internal and external evaluations in order to produce SOPs that are tested both inside and outside the organizational environment. Therefore, it is deemed necessary to develop a Standard Operating Procedure (SOP) for the student's thesis which is then socialized to the academic community, especially product users. The results of this activity are the SOP Booklet for the thesis of FEBI IAIN Palangka Raya students and the installation of Banner Stands that make it easier for students to access the SOPs.

Abstract

Islamic banking carries out business activities based on sharia principles. The economic growth of a country can be seen from the growth of financial institutions such as the banking sector. The influence of the banking sector in a country's economy is very large. The failure of a bank can have systemic consequences for a country's economy, whether conventional banking or sharia banking. This research aims to analyze and test the influence of sharia compliance reports towards the level of stakeholder trust on Indonesian Islamic banking. The indicators used in sharia compliance are profit sharing ratio, Islamic income ratio, and zakat performance ratio, while the indicators used in the level of stakeholder trust are third party funds This research approach uses quantitative methods with ex-post facto (cause-and-effect) research. The population in this research is Sharia Commercial Banks and Sharia Business Units registered with the Financial Services Authority in 2020-2022. Sample selection was carried out using a purposive sampling method, resulting in 13 Sharia Commercial Banks and Sharia Business Units for the 2020-2022 period. The data analysis method in this research is using Eviews 12. The results of this research show that partially the profit sharing ratio and Islamic income ratio have a positive and significant effect towards the level of stakeholder trust. The zakat performance ratio does not have a significant effect towards the level of stakeholder trust. Meanwhile, simultaneously sharia compliance has a positive and significant effect towards the level of stakeholder trust of 26.45%.

Abstract

Tawar-menawar adalah hal yang mubah (boleh) dalam Islam, begitu juga jika dipandang dari sudut hukum positif tawar-menawar adalah hal yang diperbolehkan. Akan tetapi jangan sampai proses tawar-menawar menimbulkan selisih paham atau bahkan sampai menjurus ke tindak kedzaliman seperti adanya unsur pemaksaan atau menyakiti perasaan orang lain. Momen tawar-menawar inilah yang menarik perhatian untuk dijabarkan lebih lanjut guna menjelaskan pola tawar-menawar yang umum terjadi pada Pasar Tradisional di Kota Palangka Raya. Penelitian ini merupakan penelitian kualitatif  deskriptif, yang bertujuan untuk menggambarkan hasil yang sistematis dan fakta yang akurat serta karakteristik di bidang tertentu dengan melakukan investigasi mendalam dengan objek penelitian pola tawar-menawar dan subjek pembeli dan penjual di Pasar Tradisional Kota Palangka Raya dan subjek pembeli dan penjual. Lokus penelitian berada di Komplek Pasar Besar Palangka Raya yang dirasa cukup untuk mewakili karakteristik dari pasar tradisional lainnya yang ada di Kota Palangka Raya. Pola tawar-menawar di Pasar Tradisional Palangka Raya secara garis besar terdiri atas bahasa, taktik atau teknik, serta gaya atau gestur. Dari hasil analisis ditemukan beberapa hal yang dirasa sesuai dan tidak sesuai dengan etika bisnis Islam terutama dalam hal taktik atau teknik yang dilakukan karena ditemukannya unsur kedzaliman dan perilaku meminta-minta yang tidak dianjurkan dalam syariat Islam. Tujuan dari tawar-menawar dalam Islam tidak sekedar memperoleh keuntungan dunia, melainkan juga memperoleh keberkahan dari apa yang diperoleh kelak.

Abstract

Strategi bisnis yang dijalankan jelas harus selalu memperhatikan tingkat produktivitas usaha. Sistem pengupahan akan mempengaruhi produktivitas kerja. Sistem pengupahan yang dilakukan pada subjek penelitian adalah dengan sistem bagi hasil, yakni keuntungan bersih dibagi menjadi 2/3 (dua pertiga) bagian untuk pemilik modal dan 1/3 (satu pertiga) bagian untuk pengelola usaha/karyawan. Berdasarkan hasil analisis diperoleh hasil bahwa BEP dalam unit untuk tahun 2019 adalah sebesar 14.281 Kg dari total produksi sebesar 40.547 Kg, dan untuk tahun 2020 sebesar 14.334 Kg dari total produksi sebesar 41.050 Kg. Sedangkan BEP dalam Rupiah untuk tahun 2019 adalah sebesar Rp 328.471.384 dari total penerimaan sebesar Rp 932.581.000, dan untuk tahun 2020 sebesar Rp 351.190.300, dari total penerimaan sebesar Rp 1.005.725.000. Secara persentase, pada tahun 2019 usaha ini hanya membutuhkan 35% dari hasil pendapatan di tahun 2019 dan 34,9% dari hasil pendapatan di tahun 2020 untuk mencapai BEP. Sedangkan hasil analisis rentabilitas diketahui pada tahun 2019 tingkat rentabilitas usaha ini sebesar 62% yang artinya, aktiva atau kekayaan yang dimiliki oleh perusahaan sejumlah Rp 371.588.000,- dapat menghasilkan keuntungan sebesar Rp 232.070.334,-. Rentabilitas usaha tahun 2020 sebesar 69% artinya kekayaan yang dimiliki sebesar 399.980.334 dapat menghasilkan keuntungan sebesar Rp 277.650.434,-. Dengan demikian maka sistem pengupahan yang digunakan oleh pengusaha Keramba Jaring Apung dianggap sudah mampu mendorong produktivitas karyawan/pengelola usaha.Kata kunci: Bagi Hasil, Break Even Point, Rentabilitas

Abstract

The purpose of this research is to analyze the accounting practices applied in the recording and reporting of accounts receivable on credit sale transactions by medium-sized wholesalers and to determine the extent to which these accounting implementations contribute to the management of accounts receivable in order to maintain cash flow and operational stability of the business. This study employs field research with a descriptive qualitative approach, aiming to explore the accounting practices of accounts receivable in credit sale transactions among medium-sized wholesalers in Sembuluh Village, Central Kalimantan. The subjects of the research were determined through purposive sampling, namely wholesalers who apply a credit sales system and are directly involved in recording accounts receivable. Data were collected through observation, interviews, and documentation, which were then validated using triangulation techniques. Data analysis was conducted using the interactive model of Miles and Huberman, which includes data collection, reduction, presentation, as well as conclusion drawing and verification. The research results indicate that the practice of accounting for accounts receivable among medium-sized wholesale traders in Sembuluh Village is still carried out manually and simply. Record keeping is done without using a computer system, relying only on receipts and notebooks, and is not organized in a regular manner or according to accounting standards. Although this recording is useful for identifying customers in debt and billing schedules, the limitations in the recording system and the absence of formal financial reports result in ineffective management of receivables, which does not support cash flow continuity and business stability.
