Abstract

Coconut plants are a superior plant in Pinamorongan Village, South MInahasa Regency. However, most of the existing coconuts are only made into copra or sold as whole coconuts, which have low value. The management aspect of mechanization is a concern because this knowledge is still low. The aim of this community service activity or community partnership program in Pinamorongan village is to provide training in optimizing management of agricultural mechanization and processing, so as to increase the value of coconut products whose value is still low. Activities are carried out by observing problems, discussions with the village government, discussions with farmers and training on optimizing existing mechanization equipment. Training on creating business models has been distributed including optimizing agricultural mechanization which has an impact on increasing farmers' income for the sustainability of their farming business. As a result of this activity, farmers become more knowledgeable and skilled in management and business aspects. Future recommendations for increasing farmers' income, apart from coconut, include developing the cultivation of high-value agricultural commodities such as vanilla and chilies

Abstract

Macadamia (Macadamia integrifolia) is a high-value crop not widely known in Indonesia and still processed using conventional shelling methods that are time-consuming and inefficient. This study aimed to design and evaluate the PTR-TETA20 macadamia nut sheller to improve post-harvest efficiency. The research was conducted from May to July 2024 at the Faculty of Agriculture, Sam Ratulangi University. The methodology involved the design, construction, and performance testing of the machine using experimental methods and descriptive data analysis. The PTR-TETA20, measuring 30 × 23 × 113 cm and powered by a 1/4 HP motor with a pulley and V-belt system at 1467 RPM, was tested using 1 kg of macadamia nuts in three repetitions. The average working capacity reached 38.43 kg/hour, with a yield of 92.52%. Nut integrity was recorded as 40.22% whole, 36.10% halved, and 23.66% broken. Moisture content was 2.6% (whole), 2.56% (halved), 2.83% (broken), and 9.52% (shells). The results indicate that PTR-TETA20 offers a practical shelling solution for small-scale producers. However, machine performance can be improved by optimizing roller spacing and ensuring uniform nut drying.
