Abstract

Palm oil is an industrial crop which generally enters its unproductive age at the age of 21 and must be cut down at the age of 25. But there are also those who, at the age of 16, are no longer productive due to various factors, such as seeds or infertile soil. The stems of this oil palm plant are considered as waste and are usually used only as compost. This study attempts to analyze the characteristics of palm wood planks and compare them with the boards commonly used for making furniture in UMKM. In this case the furniture board used as a comparison is the meranti board. Meranti wood is classified as class IV wood. From the results of the study using the ASTM D638 standard for tensile testing, it was found that the strength of palm wood aged 16-20 years was 4.47 MPa, palm wood aged 21-25 years was 14.41 MPa and Meranti wood was 56.58 MPa. The SNI 03-3958-1995 standard for compression testing obtained the compressive strength of 16-20 year old palm wood of 9.93 MPa, 10.05 MPa of 21-25 year old palm wood and 24.86 MPa of Meranti wood. Standard SNI 03-3959-1995 for flexure testing showed that the strength of palm wood aged 16-20 years was 4.50 N/mm2, palm wood aged 21-25 years was 21.17 N/mm2 and meranti wood was 28.13 N/mm2.

Abstract

ChatGPT said: The processes of irrigation and fertilization in agriculture are time-consuming and physically demanding, as farmers typically irrigate twice daily and fertilize every three to four days. These repetitive tasks can lead to fatigue and reduced efficiency. To address this, we have developed an automated system for irrigation and fertilization that enables farmers to manage these activities remotely via smartphone. The system utilizes a microcontroller programmed based on specific agricultural needs and connected to the internet through Wi-Fi. This connectivity allows farmers to activate irrigation or fertilization with a single tap on their smartphones, anytime and from anywhere. The system aims to increase efficiency, reduce labor, and provide a more cost-effective and precise method of managing agricultural land. By automating routine tasks, farmers can better allocate their time and energy while ensuring optimal crop growth. The final outcome of this research is expected to be applicable directly in the field, allowing for real-world testing and refinement. Furthermore, the findings will be shared through a scientific publication to support knowledge.

Abstract

Surface roughness is a critical parameter that influences product quality in machining operations. According to ISO 1320–1987, surface roughness is characterized as the arithmetic mean deviation of surface irregularities from the nominal profile. In mechanical component manufacturing, controlling surface roughness is essential due to its relationship with friction, lubrication behavior, and wear performance. Tool geometry and cutting parameters are known to significantly affect surface texture quality. This study investigates the influence of depth of cut using a Sumitomo insert with a 1.2 mm nose radius on the surface roughness of S45C steel machined by CNC turning. An experimental procedure was adopted, using depth-of-cut variations of 0.3 mm up to 1.5 mm. The feed rate was set at 0.1 mm/rev and the spindle speed followed the constant surface speed mode (G96). Surface roughness values were measured with a stylus profilometer. The experimental results indicate that all tested depth-of-cut settings fall within roughness grade N7, except for the 0.3 mm depth of cut, which achieved grade N6.
