Abstract

Kopi merupakan salah satu komoditas pertanian yang ada di Indonesia. kopi adalah tanaman perkebunan yang telah lama menjadi tanaman yang dibudidayakan. Tanaman kopi berasal dari afrika dan asia selatan, termasuk famili Rubiaceae dengan tinggi mencapai 5 meter. Daun tanaman kopi memiliki panjang 5-10 cm dan lebar daun 5 cm dengan bunga kopi berwarna putih dan buah kopi berbentuk oval berwarna hijau kuning kehitaman. Di Indonesia, pengeringan biji kopi masih dilakukan secara alami, dengan cara dikeringkan langsun dengan cara dijemur. Dengan pengeringan secara alami ini terdapat kelemahan yaitu proses pengeringan yang bergantung pada cuaca. Sehingga jika tidak ada sinar matahari dan ketika terjadi hujan maka hasil pada proses pengeringan biji kopi dengan menggunakan sinar matahari kualitasnya akan berkurang. Alat pengering buatan merupakan salah satu alternatif dalam proses pengeringan biji kopi. Untuk menjaga kualitas hasil pengeringan biji kopi maka dilakukan teknologi baru menggunakan mesin pengering biji kopi type drum rotary yang sederhana menggunakan gas LPG sebagai bahan utama pembakaran terhadap pengeringan biji kopi, Pelngujilan yang pelrtama dillakukan delngan melnggunakan mata nozzlel no 1 selbagail alat pelngelrilngan melndapatkan hasill biljil kopil pelngelrilngan pada suhu 450c,50℃,60℃ pada silsil kanan dan kilril drum pelngelrilng.

Abstract

The effectiveness of palm fruit release at the Thresher station is greatly influenced by the stability of the drum rotation speed. However, operational conditions at PTPN IV Kebun Mayanng indicate instability of rotation due to variations in fruit size and fluctuations in the energy supply from the Boiler, so that the threshing process does not always occur optimally. This study aims to analyze the effect of the Thresher drum rotation speed on the ability to release palm fruit from the bunch and its impact on fruit damage under field conditions. The research method uses a mixed approach through direct observation at the Thresher station and quantitative measurements at three rotation variations, namely 20, 23, and 26 RPM. The measurement results are then analyzed qualitatively based on actual operational conditions. The results show that a speed of 23 RPM is the most stable rotation, resulting in effective fruit release with an acceptable level of fruit damage. A rotation of 20 RPM provides lower fruit damage, but causes less optimal fruit release and increases the number of fruit left on empty bunches. Meanwhile, a rotation of 26 RPM is able to increase the effectiveness of release, but causes very high fruit damage due to the influence of excessive centrifugal force. Overall, this study demonstrates a trade-off between release efficiency and fruit damage. Too high a rotation speed increases release efficiency but increases fruit damage, while too low a rotation speed decreases release efficiency and increases loss, albeit with less damage

Abstract

This study aims to design and analyze the performance of an automatic grass chopper and vacuum cleaner with a gasoline engine drive system as an appropriate technological solution to improve environmental cleaning efficiency. The main problem in this study is that the grass cleaning process is still done manually, which requires time, energy, and significant operational costs. The research method used is the design method which includes the design, assembly, and performance testing stages of the tool. The machine was designed using a Honda GX 200 gasoline engine, a centrifugal blower, a pulley transmission system, a grass chopper, and a container for the chopped results. Tests were conducted based on variations in engine speed to determine the chopping capacity, noise level, and fuel consumption. The results showed that the machine is able to carry out the cutting, chopping, and vacuuming processes of grass in an integrated manner with more effective performance than the manual method. Under optimal conditions, the machine is able to produce grass chopped up to 2.5 ounces in 6 minutes with an average noise level of 96.4 dB. In addition, the use of the machine has been proven to speed up the work process and reduce the need for manual labor. Thus, the designed machine has the potential to become an efficient and applicable technological innovation in supporting environmental cleanliness.

Abstract

This research aim For make Design and Construction Machine Peanut Skin Peeler as well Capacity 100 kg/hour. Based on the results of the peanut roasting and peeling experiments, it can be concluded that the roasting time affects the final weight of the peanuts, the peeling results, and the quality of the peanut seeds produced. and a roasting time of 10 minutes by a sand temperature of 30 °C, the weight of the peanuts decreased from 1 kg to 0.95 kg. After peeling, the weight of the peanut seeds was 0.60 kg and the weight of the peanut shell was 0.35 kg. The percentage of unbroken peanuts reached 97%, while only 3% were broken. After roasting for 20 minutes, the final peanut weight decreased to 0.90 kg. The peeling results proved that the weight of the seeds was 0.57 kg and the weight of the shell was 0.33 kg. The percentage of whole peanuts decreased to 80%, while the percentage of broken peanuts increased to 20%. The experimental results also proved that the capacity of the peanut peeling machine reached 100 kg/hour by both experiments. Longer hulling times reduce the moisture content and weight of the beans, but increase the level of damage during hulling. Therefore, a hulling time of 10 minutes at 30°C yields the best results, producing more accurate hulling of the beans and reducing the level of damage

Abstract

Problems arise when the electrical energy generated by solar panels is not constant throughout the day due to changes in the sun’s position. One way to address this is to adjust the panel’s angle—either manually or automatically—in accordance with the sun’s movement. The objectives of this study are to analyze the electrical charging system of a plant sprayer equipped with a 100-watt solar panel, to determine the optimal angle for the solar panel to generate electrical energy, and to measure the voltage, current, and power produced by the solar panel during the battery charging process. The analysis method was used to determine the effect of variations in the solar panel angle on the voltage, current, and electrical power generated. The study aimed to identify the optimal angle for generating electrical energy to charge the pump system and to assess the performance of the solar-powered crop sprayer at various panel tilt angles during charging, based on field test results. Research Findings: Optimal Charging System: The battery charging system for the crop sprayer achieves optimal performance when a 100-watt solar panel is installed at a tilt angle of 20^∘. At this angle, the solar panel produces the highest average current (3.873 A) and the highest charging power (72.409 W) compared to a 10^∘ tilt or a 0^∘ flat position. Power Increase Characteristics: Changes in the tilt angle were found to affect the charging power linearly and in the same direction. Every 1° increase in tilt angle (up to the test limit of 20°) will increase the battery charging output of the sprayer by a constant 1.036 watts. The difference in power efficiency only becomes statistically significant when the angle is changed directly from the horizontal position (0°) to the optimal angle (20°). Conclusions from this study: Charging Time Conditions: The charging duration is not affected by changes in the solar panel tilt angle. This is due to the protection system in the sprayer’s Solar Charge Controller (SCC), which limits the maximum current threshold to ensure battery safety, thereby keeping the charging time constant.

Abstract

This study aims to describe the design and construction of a cocoa bean grinding machine with a power of 0.5 hp. Based on the results of the cocoa bean grinding machine performance test and simple linear regression statistical data analysis using SPSS software in Chapter IV, several conclusions can be drawn as follows: Performance and Grinding Capacity of the Machine The grinding machine has a stable performance in producing fine products at a grinding duration of 2 minutes. At a variation of 1000 grams of input load, it produces an average of 358.33 grams of fine products, a 2000 gram load produces 733.33 grams, and a 3000 gram load produces 1066.67 grams. The Effect of Material Weight on Grinding Results (Regression Analysis): Fine Results: The weight of cocoa bean input has a positive and significant effect on fine results. Every 1 gram increase in cocoa weight will increase the fine results by 0.354 grams. Coarse Results: The weight of cocoa bean input has a positive and very significant effect on coarse results. Every 1 gram increase in cocoa weight causes an increase in coarse results by 0.642 grams. This shows that the majority of additional loads will tend to increase the coarse fraction if the grinding time is limited to only 2 minutes. Unmilled Material: The weight of cocoa bean input does not significantly affect the amount of unmilled material 0.212 > 0.05. The amount of unmilled material tends to be constant at an average value of 325 to 333 grams, which indicates the existence of a certain mechanical limit/dead space in the machine's grinding chamber. Machine Noise Level: The machine operates with a high noise level, ranging from 96.6 dB to 99.5 dB, which has exceeded the safe threshold for human hearing for long duration (85 dB). Based on the regression analysis, the addition of material weight has a negative coefficient (-0.001) which means it slightly dampens the sound, but the effect of this material weight addition is statistically insignificant (0.208 > 0.05).
