Abstract

In Indonesia, rice is the main food crop besides corn, sago and tubers. The choice of rice as the main source of carbohydrates is because rice has superior plant characteristics when compared to other carbohydrate sources. In cultivating seed crops to be one of the main factors that determine success. Much of the increase in rice production has been supported by quality (certified) seed farmers. Rice production in North Sumatra in 2021 amounted to 2,126,765 tons of dry milled grain (GKG) experienced an increase in production of 330,665 tons compared to 2020, in 2004 rice production in North Sumatra only reached 1,796,100 tons. The increase in production was due to an increase in the harvested area of 424,650 hectares in 2021, when compared to the harvested area in 2020, namely the harvested area of only 366,590 hectares. think about the expected performance (results), if the performance is below expectations, the customer is not satisfied. If the performance meets expectations, the customer is satisfied. If the performance exceeds expectations, the customer is very satisfied or happy. This research was conducted in the village of Aras, District of Deli Serdang, using the non-probability sampling method. The results showed that farmers' preferences and satisfaction with the attributes of planting rice using Ciherang seeds were sufficient to satisfy farmers. Keywords: Rice, Chiherang, Satisfaction, farmers

Abstract

Margin tissue detection during intraoperative laparoscopic liver resection (LLR) is required to prevent tumor recurrence and reduce the likelihood of further surgery. This study proposes an electrical impedance spectroscopy (EIS) method for margin tissue detection in LLR to determine the boundary interface of normal and cancerous tissue. The proposed method of this study has three objectives: (1) designing the electrode array configuration to collect multiple EIS impedance measurements, (2) implementing the Feedforward Neural Network (FNN) to classify the orientation of margin tissue relative to the electrode array by using time-difference impedance indexes, and (4) governing the inflection point method based on impedance indexes to detect the margin tissue location. The proposed method is evaluated by a 3D numerical simulation of liver tissue composed of cancerous lumps with Iac = 1 mA alternating injection current  at frequencies: lf = 1 kHz and hf = 100 kHz. The electrode array is composed of 16 electrode pairs each for injection current and voltage measurements. The variation of margin tissue orientation relative to the electrode array direction was considered to occur in unidirectional, perpendicular, and diagonal direction with noise variations (Signal-to-Noise-Ratio: 50 to 90 dB). The FNN trained on 2,400 data points achieves True Positive Rate (TPR) value as 90.2%, 99.4%, and 96.6% for diagonal, perpendicular, and unidirectional respectively in margin tissue orientation classification, while the inflection point method detects margin tissue location with 75% location at the unidirectional orientation (y-axis).

Abstract

This study aims to find out and explain the definition, history and law in Islam towards e-money as a means of payment, as well as the positive and negative impacts of using e-money itself. The research method used is a qualitative method. The research approach used is the study literature review approach, which is a method that identifies and evaluates research results and ideas that have been produced by researchers and practitioners. The literature method comes from various sources, such as books and journal articles. The results of this study know that the law of using e-money in an Islamic perspective as a means of payment is halal or permissible.

Abstract

Pembangunan konstruksi umumnya menggunakan bahan mortar. Mortar yang digunakan banyak diaplikasikan pada dinding baik sebagai plesteran maupun sebagai bahan perekat dalam suatu pasangan baik itu pasangan bata, pasangan keramik lantai atau dinding, atau sebagai perekat pasangan pondasi. Umumnya mortar terbentuk dari campuran bahan perekat dan bahan pengisi, bahan perekat ini umumnya menggunakan semen sebagai perekat dan pasir sebagai bahan pengisi, namun tak sedikit pula banyak mortar yang menggunakan bahan perekat dengan tambahan kapur. Seperti yang diketahui juga, mortar memiliki banyak kegunaan dalam dunia konstruksi, oleh sebab itu tak jarang para peneliti melakukan penelitian terhadap mortar. Penelitian ini bertujuan mencari seberapa besar nilai karakteristik mortar pada limbah serbuk bata merah sebagai bahan substitusi semen menggunakan pasir bengawan solo terhadap sifat mekanik mortar. Hasil penelitian diketahui bahwa serbuk bata merah memiliki pengaruh kuat tekan menjadi semakin kuat secara maksimal diperoleh nilai sebesar 5,12 kg/cm2 dengan campuran serbuk bata merah sebesar 10 %.  Serbuk bata merah juga memiliki pengaruh dapat meningkatkan dan menurunkan nilai berat jenis mortar serta serbuk bata merah juga memiliki pengaruh terhadap penurunan daya serap air dimana penurunan daya serap air secara maksimal diperoleh dengan campuran serbuk bata merah dengan nilai daya serap air sebesar 10,06 %

Abstract

Dalam industri pariwisata, pemesanan paket perjalanan yang sesuai dengan preferensi pelanggan sering kali terkendala oleh keterbatasan sistem manual dan kompleksitas pilihan. Penelitian ini bertujuan untuk mengembangkan sistem pemesanan wisata berbasis web yang menggunakan algoritma genetika guna mengoptimalkan rekomendasi paket berdasarkan anggaran, durasi perjalanan, dan jumlah peserta. Metode ini meniru mekanisme seleksi alam melalui tahapan inisialisasi populasi, evaluasi fitness, seleksi, crossover, dan mutasi untuk menemukan kombinasi optimal destinasi, akomodasi, dan transportasi. Sistem diuji dengan berbagai skenario input, menunjukkan bahwa algoritma mampu menghasilkan rekomendasi dalam waktu kurang dari 5 detik dengan efisiensi anggaran tinggi dan jadwal perjalanan yang sesuai batas waktu maksimum. Hasil penelitian menunjukkan bahwa integrasi algoritma genetika dalam sistem pemesanan berbasis web secara signifikan meningkatkan efisiensi, akurasi, dan personalisasi layanan bagi pelanggan.
