Abstract

Telah dilakukan penelitian yang bertujuan membandingkan konsentrasi glukosa normal antara hasil pemodelan dengan hasil eksperimen dari 6 orang pasien glukosa normal. Pola-pola grafik yang dihasilkan pada masing-masing pasien glukosa normal berbeda-beda walaupun setiap pasien mendapatkan perlakuan yang sama. Hasil penelitian menunjukan bahwa pemodelan cocok digunakan untuk data hasil eksperimen pada wanita berumur 17-20 tahun dimana diperoleh konsentrasi glukosa statis 73 mg/dl. Hal ini dikarenakan ada beberpa harga konstanta laju transport (K) hasil pencocokan kurva yang bernilai sama, yaitu pada parameter Fluk glukosa (Fg) 80000 mg/dl s, konstanta laju transport pengurangan glukosa orde pertama (K1) 24,7 s-1, konstanta laju transport eliminasi ginjal (K2) 72 s-1, konstanta laju transport pengurangan insulin-glukosa (K3) 13,9 s-1, konstanta laju transport metabolisme pankreas (K4) 14,3 s-1. Adanya beberapa parameter yang memliki nilai sama antara pemodelan dan juga eksperimen ini berarti bahwa pasien dalam menjaga keseimbangan glukosa plasma darah dalam kesehariannya sama, glukosa plasma darah seimbang bila efisiennya organ pankreas dan ginjal.

Abstract

Tingkat kematangan Tandan Buah Segar (TBS) kelapa sawit merupakan faktor penting bagi kualitas cruide palm oil (CPO) yang tinggi. Metode penentuan tingkat kematangan TBS kelapa sawit secara elektronik dibutuhkan untuk menggantikan metode tradisional yang mengandalkan pengalaman. Pada penelitian ini metode optik spektroskopi fluoresensi dengan laser dioda modulasi digunakan untuk evaluasi tingkat kematangan TBS kelapa sawit. Sistem optik spektroskopi fluoresensi terdiri dari laser dioda 640 nm 20 mW yang dapat dimodulasi CW, 1 KHz dan 10 KHz dengan dua fotodioda FDS 100 sebagai detektor cahaya dan rangkaian multiboard sebagai penguat fotodioda. Sampel yang digunakan adalah varietas Tenera 23 TBS. Setiap TBS disinari pada tiga bagian pangkal, tiga bagian tengah dan tiga bagian bawah. Tegangan keluaran dari setiap laser modulasi diukur dengan multimeter. Hasil menunjukkan bahwa TBS dengan tingkat kematangan F3 mempunyai tegangan tertinggi. Perbedaan ketiga mode modulasi menunjukkan bahwa cahaya dengan mode CW memberikan nilai tegangan yang lebih besar karena waktu hidup (on) laser lebih lama, namun sensitivitas membedakan tingkat kematangan terdapat pada modulasi 10 KHz.

Abstract

Muhammadiyah is an amar ma'ruf nahi munkar movement that has proved capable of transcending time for more than a century. During this time, Muhammadiyah has demonstrated its ability to serve the Indonesian people via humanitarian endeavors in the sectors of da'wah, education, and health. Along with the organization's growth, Muhammadiyah began to pioneer and extend its worldwide presence in 2000. PCIM China is one of the PCIMs that are currently being developed. Initiated in 2016 and subsequently formally created in 2016, PCIM China was able to gather together Indonesian students studying in China who had ideological and biological links to Muhammadiyah. However, when the COVID-19 epidemic struck, PCIM China was confronted with a number of issues that required treatment. First, due to the pandemic, all PCIM China administrators had to return to their homeland. Second, the number of cadres is limited. Students and students who join PCIM China do not only consist of cadres who really understand the organization, but also students who have never been involved in active management at Muhammadiyah. Third, there is no business charity that can be used as the main activity of PCIM China. The purposeful solution is the establishment of a productive social business in the form of activities that facilitate religious education and religious tourism activities in China in collaboration with the China Islamic Association (CIA). Since 2019, there has been good communication, including discussing the progress of Islam in China and the CIA's success in building mosques throughout China and madrasahs, or Islamic schools, in Beijing City. The implementation method that will be used is consult-training, Implementation of the solution is carried out by providing assistance, starting from planning the establishment of a productive business charity up to the operational stage. Apart from that, training will also be carried out for prospective business charity managers so that later they can manage productive business charities well.

Abstract

This study examines the concept of leadership in Islam through a qualitative analysis of the hadiths of Bukhari and Muslim. It explores the deeper meaning of leadership as a trust that carries moral and spiritual responsibility. It does so using a desk research methodology. Key findings demonstrate that everyone is responsible for leadership, what happens with misguided leadership, and what happens with unjust leadership. The ma'anil hadith method facilitates a deeper understanding of key terms, enriches the interpretation of hadith, and demonstrates its relevance to the modern world. The study finds that the hadiths outline the principles of accountability, transparency, and justice, which remain crucial for ethical and responsible leadership today.

Abstract

This study aims to review the system commission in the TikTok Affiliate program from the perspective of muamalah fiqh law. The background of this research is based on the rapid development of digital businesses and social media, especially TikTok, which opens up new economic opportunities through affiliate programs. The research method used is qualitative with a descriptive-analytical approach, involving literature studies, in-depth interviews with physicists and digital business practitioners, and analysis of documents related to the TikTok Affiliate program. The results of the study show that the system in TikTok Affiliate reflects the principles of fairness and transparency regulated in fiqh muamalah. The program allows for a proportional commission sharing with the content creator's efforts, and provides a clear and transparent monitoring mechanism. However, to ensure compliance with sharia, it is important that the products promoted by creators are halal products and that all provisions regarding commissions are explained in detail to avoid the element of gharar (uncertainty). The conclusion of this study confirms that the commission system in TikTok Affiliate can be considered in accordance with the principles of fiqh muamalah, as long as all parties involved ensure that transactions are carried out fairly, honestly, and transparently, and the products promoted are in accordance with halal provisions.
