Abstract

Preparation of cassava seedlings (cuttings) is usually done manually by farmers using slash or hand saws which are considered less effective today. With these problems, TEP-1 Type Cassava Seed Cutting Tool was made as a solution in the effort to meet the needs of cassava seedlings whose performance needs to be tested on several types and varieties of cassava plants. In this study a completely factorial completely randomized design (RALF) method was used using two treatment factors. The first treatment factor is the cutting machine RPM tested at three levels including the RPM 3500, RPM 4000, and RPM 4500. The second treatment factor is the cassava plant varieties tested at three levels, namely by using Kasetsart varieties, Thailand varieties, and Garuda varieties. The test results were analyzed by analysis of variance using the SAS program. The working capacity of Petokong tools in the Kasetsart variety is 9900 seedlings / hour at RPM 3500, 10620 seeds / hour at 4000 RPM, and 11340 seedlings / hour at RPM 4500. While in Thailand varieties, the working capacity of Petokong tools is 5500 seedlings / hour at RPM 3500 , 8250 seedlings / hour at 4000 RPM, and 8700 seedlings / hour at 45,000 RPM. The working capacity of the Butters in the Garuda variety is 5220 seeds / hour at 3500 RPM, 6300 seedlings / hour at 4000 RPM, and 7020 seeds / hour at 4500 RPM. Based on analysis of variance, the interaction between engine RPM factors and cassava varieties did not significantly affect work capacity, fuel consumption, and the level of uniformity of the performance results of the Supporting Equipment. Keywords: Cassava, Cassava Seedlings, Petokong, Work Capacity.

Abstract

In addition to other horticultural goods, Indonesia is a major producer of the pumpkin fruit that we see all the time. This fruit is often used to make a variety of foods, and it offers several health advantages. The transformation into dried food is a processing method with enormous commercial potential on a global scale. One of the specific post-harvest treatments required to increase the storage life of horticultural fruits like pumpkin is to convert it into chips. Vacuum frying is the preferred technique of processing these chips because it increases crispiness and prolongs the shelf life of the finished product. A new invention for the community at the research site is the use of a vacuum machine to process pumpkin chips. This is due to the practicality of the process and the ease of obtaining the raw ingredients. The purpose of this research is to find out how changing the temperature and pressure affects the pumpkin chip quality. The experiment was carried out with three different pressure levels (-66 cmHg, -68 cmHg, and -70 cmHg) with three different temperature changes (75 °C, 80 °C, and 85 °C). The approach used was a two-factor Randomized Block Design (RBD). Organoleptic evaluation, frying time, water content, and yield are some of the parameters measured. Pumpkin chip water content, frying time, and organoleptic test results are all affected by pressure and temperature, according to the findings. Fry for 41 minutes with a water content of 7% for the finest pumpkin chips. Keywords:  Pressure, Pumpkin fruit, Temperature, Vacuum Frying.

Abstract

Cassava is one of Indonesia’s leading food commodities, especially in Lampung Province. However, cassava harvesting is still predominantly done manually, which is time-consuming, labor-intensive, and prone to crop damage. This study aims to evaluate the effectiveness of cassava harvesting using a Kubota mechanical harvesting implement compared to traditional manual methods. The research was conducted in Bandar Mataram District, Central Lampung Regency, over an area of 0.75 hectares and observed parameters including harvest time, tuber damage, losses, and labor efficiency. Results showed that the harvesting implement significantly improved efficiency, allowing one machine to harvest up to 1.07 hectares per day, compared to only 0.045 hectares per day per person using manual labor. Tuber damage and losses were also reduced from 7% in manual harvesting to 1.59% with the implement. Furthermore, the implement created soil ridges suitable for direct replanting without further tillage. Despite its advantages, some operational weaknesses were identified, such as the need for stem cutting and transportation improvements. Overall, the use of mechanized harvesting tools enhances cassava farming efficiency and has the potential to reduce labor dependency and improve farmer productivity.

Abstract

Cassava production not only produces tubers and leaves that can be used asvegetables, but there is also waste produced, one of which is cassava stems. Sofar, cassava stem waste has not been widely utilized by farmers, so after thecassava is harvested, the cassava stems are just left lying on the land. This studyaims to reduce cassava stem waste by reducing the size using a multi-purposeChopper tool with several variations in engine rotation per minute (RPM). Thisresearch was conducted at the Agricultural Machinery and Equipment PowerLaboratory, Department of Agricultural Engineering, Faculty of Agriculture,University of Lampung in March 2025. The treatment used 3 variations of RPM,namely 1500, 1800, and 2100 where each used 3 different input amounts, namely:input of 3 stems, 4 stems, and 5 stems and each RPM was repeated 3 times. Theresults showed that chopping using the RPM setting of 2100 and the input amountof 4 cassava stems had the best work capacity with a value of 150.8 kg/hour. Thelowest fuel consumption using RPM variation of 1500 and the amount of input of3 sticks with a value of 591.6 ml/hour.

Abstract

This study aims to evaluate the performance of the Rabakong slicer-type machine and compare it with previous models. A Completely Randomized Design (CRD) was used with two factors: machine rotation speed (1500, 2000, and 2700 RPM) and the number of cassava stems input (2, 3, and 4 stems). Each treatment was repeated three times for 10 minutes. Observed parameters included work capacity (kg/h), fuel consumption (l/h), percentage of product loss, slicing uniformity (%), and ergonomic aspects of operator performance. The results showed the highest work capacity of 522.2 kg/h at 2700 RPM with 4 stems. The lowest product loss (0.82%) occurred at 2000 RPM with 3 stems, while the lowest fuel consumption (0,680 l/h) was recorded at 1500 RPM with 4 stems. The highest slicing uniformity (58%) was obtained at 2700 RPM, particularly for output passing through a 0.1 mm mesh. The Rabakong slicer-type machine falls under the moderate workload category with a CVL of 41–47% and an operator heart rate of 125–135 bpm, still within safe limits (Tarwaka, 2004). This machine outperforms its predecessor in capacity, uniformity, fuel efficiency, and operator comfort. Therefore, it is recommended as an effective solution for processing cassava stem waste into value-added products such as animal feed or compost.
