White jabon fruit (Anthocephalus cadamba Miq.) was identified as a potential tropical plant for use as a biosorbent because it contained cellulose, the adsorption capacity of which could be enhanced through an activation process. The activation process of the biosorbent in this study was carried out chemically using NaOH and coated with humic acid from peat water, with the aim of increasing the…
This study aims to design and implement a load cell sensor system for fresh fruit bunches (FFB) based on mass, using a conveyor and load cell sensor. The system is designed to detect the weight of the bunches in real time and separate them according to the minimum weight criteria established by the Indonesian Ministry of Agriculture Regulation No. 1 of 2018, which is above 3 kg. The mass de…
A machine vision system has been developed to assist in the automatic and real-time sorting and grading of oil palm Fresh Fruit Bunches (FFB), especially for detecting their ripeness level. The system consists of a computer vision unit, a conveyor, a control circuit, and a separation arm. The conveyor speed and the camera's frame rate per second (FPS) influence the accuracy of image detection. …

This final project presents the development of a new numerical method called the New Bracketing Iteration Method (MIBB) for solving single-variable nonlinear equations. MIBB is a modification of the regula-falsi method, incorporating a combination of the bracketing approach and adaptive linear interpolation. The main advantages of this method are its derivative-free nature and guaranteed global…
This final project discusses a new family of optimal fourth-order iterative me- thod to solve a nonlinear equation. This method is obtained by modifying Newtons method using a weight function. Analytically using the Taylor expan- sion and geometric series that the iterative method has a convergence order of four and efficiency index is 1.587. Computational tests show that the new me- thods in t…
Depression is a mental health disorder that often occurs in society, which is characterized by unstable mood swings. Synthetic antidepressants are quite widely available, these antidepressant drugs have side effects so that alternative antidepressant drugs from herbal plants are needed which have fewer side effects. One of the plants that has the potential as an antidepressant is areca nut. The…
The manual classification process of fresh fruit bunches (FFB) in oil palm has limitations, particularly with stacked objects, due to subjective assessment and low efficiency. This research develops an automated system based on computer vision using the YOLOv8 algorithm to detect and classify normal and defective FFB (empty bunches, rotten, long stalks, and long thorns) stacked on a conveyor. A…
The multispectral imaging has been used in agriculture to evaluate fruits and vegetable. This system consists of a light source, monochrome camera and two color filters. In the implementation of the size of the sorted and graded FFB, it varies causing varying intensity because the working distance which varies causes errors in determining the maturity of oil palm FFB because the shadow of the…
Oil palm is a major commodity in Indonesia’s plantation industry. However, the identification process of fresh fruit bunch (FFB) varieties such as Dura and Tenera is still carried out manually and destructively, making it inefficient and tiring. This research aims to develop a non-destructive identification system based on ultrasonic sensors and Artificial Neural Networks (ANN) to distinguish…
Oil palm is a primary commodity in Indonesia’s plantation industry, with the production of fresh fruit bunches (FFB) increasing annually. However, the process of identifying FFB varieties such as Dura and Tenera is still performed manually using axes in a destructive manner, which is inefficient and damages the surface of the fruit. Non-destructive imaging methods have emerged to address this…
This research is titled "Mapping the Potential of Groundwater Using the Schlumberger Configuration Geoelectric Method in Jati Mandiri Housing, Air Putih Village, Tuah Madani District, Pekanbaru City". The main objective of this study is to evaluate the groundwater resource potential in the area, where most residents still rely on boreholes and dug wells as sources of clean water. The geoelectri…
This research aims to analyze the implementation of Regent Regulation Number 81 of 2021 by the Kampar Regency Public Works and Spatial Planning (PUPR) Department in road repairs in Bangkinang Kota District. Repair and maintenance of road infrastructure has an important role in supporting community mobility and regional economic growth. This research uses George C Edward III's theory, divided in…
tourism is a sector that has great potential in improving the regional economy, including in Indragiri Hulu Regency. Inhu Park as one of the tourist destinations in the area has its own appeal, Inhu Park is one of the tourist destinations that has great potential to be developed, both in terms of natural beauty, facilities, and socio-cultural attractions. This study aims to Analyze the Communic…
Human resources are a crucial factor in determining the success of a company, including in the hospitality sector. Hotel Pangeran Pekanbaru, as a hospitality service provider, faces challenges in retaining competent employees amid increasingly fierce competition. This study aims to analyze the influence of leadership and organizational culture on employee retention at Hotel Pangeran Pekanbaru. …
This final project examines the dynamics of the Fermi-Pasta-Ulam-Tsingou-α (FPUT-α) system, focusing on double-mode excitations and the equipartition of energy phenomenon. Through numerical simulations, it is investigated how variations in initial energy and excitation mode combinations influence energy distribution among modes. The results show that at low energy levels, energy remains uneve…
PT. Prima Transportasi Servis Indonesia, a partner of PT. Riau Andalan Pulp and Paper, focuses on the transportation and distribution of wood for the production of quality paper, employing approximately 900 people. The company requires a training program to enhance the competencies and productivity of its employees; however, the manual registration process for training poses challenges for the …
The Kampar River is one of the important rivers located in Riau Province, where it is formed by the confluence of two nearly equally large rivers, namely the Kampar Kiri River and the Kampar Kanan River. The Kampar Kiri River is a watercourse where the fish species commonly found are primarily edible fish, making this river one of the centers of fisheries production in Riau. The Channidae famil…
Coastal mangrove natural resources are very diverse, including microorganisms. Phosphate-solubilizing bacteria (PSB) are one of the microorganisms that can be utilized from the mangrove ecosystem. PSB can be used as a biofertilizer in agriculture to reduce excessive use of chemical fertilizers. The aim of this research is to isolate and characterize PSB from sediment and mangrove rhizosphere sa…
