Abstract:

A candlenut peeling machine is a technological innovation aimed at improving the efficiency of separating candlenut seeds from their shells. Hand-peeling candlenuts requires a lot of time and effort, and it carries a high risk of damaging the candlenut kernels due to uneven impact. This candlenut peeling machine is equipped with a mechanism that reduces seed damage and increases productivity. The machine can be operated manually or semi-automatically and works on the principle of utilizing pressure and friction to break the shell without damaging the seeds inside. Experimental results show tha

Abstract:

With the traditional method, 1 worker can only produce 1.5 kg/hour of candlenut. When it rains, the candlenut cannot be dried in the sun, so the production of candlenut stops. Candlenut which is not completely dried, cannot produce quality candlenuts when cracked. This study aims to increase the quantity and quality of the candlenut seed production through the design of an integrated drying and filter component of the pecan shell separator using the 3 variable machine capacity test method (drying temperature, drying time and motor rotation) needed to produce optimal conditions for production c

Abstract:

Candlenut shell (Aleurites moluccana Willd) is a waste produced from processing candlenut plants with a fairly hard texture. The use of candlenut shells as fertilizer, especially in Central Sulawesi, has not been done so much. The aim of this study was to determine the levels of calcium (Ca) and potassium (K) in candlenut shells. Calcium and potassium levels were determined using an atomic absorption spectrophotometer (AAS). The results show that the average calcium level in the candlenut shell is 0.315 ± 0.09%, while the average potassium level is 0.090 ± 0.01%. The results of Ca and K in can

Abstract:

Candlenut shell is an agricultural waste which can be processed into low-cost active carbon. Activated carbon cannot be used directly as a heterogeneous catalyst in transesterification of biodiesel because of its low alkalinity, thus treatment is required. In this study, the carbonization of candlenut shells was conducted at 500°C for 4 h. The activated carbon obtained was modified by impregnation with potassium hydroxide (KOH) solution. KOH concentration used was 50g/150 ml aqua des and impregnation time was 24 h. The impregnated activated carbon was characterized by Scanning Electron Microsc

The study will investigate how various activator concentrations affect the ability of adsorbents based on candlenut shells to bind molecules.
