Abstract

This study aims to analyze the chemical and sensory characteristics of marshmallows made from young coconut water and coconut sugar, as natural sources of potassium and sodium. The parameters analyzed include potassium content, sodium content, moisture content, pH, and sensory properties. The study employed a Completely Randomized Design (CRD) with four treatments and three replications, varying the concentrations of young coconut water and coconut sugar. The results showed that potassium levels ranged from 3,208–4,345 mg/kg and sodium levels from 482–1,083 mg/kg. The resulting marshmallows had relatively high moisture content (28.15–39.38%) and low pH (5.03–5.93). Sensory evaluation indicated good acceptance by panelists, characterized by a chewy texture, distinctive coconut sugar aroma, and natural brown color.

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.
