Measuring of grain moisture content rapidly and accurately is necessary in riel application, i.e. to estimate the optimum stage of harvesting, predicts grain storage periods, decides the grain price, and for research and development purposes. Since grain moisture content is usually measured conventionally, beside time-consuming, it is expensive and less practice. This research aims to evaluate the possibility of a simple capacitance type sensor for measuring grain moisture content. The sensor is designed from copper probe constructed in parallel with dimension of 5x10 cm, width of 3 cm. The sensor is connected with a suitable signal conditioning of astable multi-vibrator circuit, microcontroller for data acquisition, and LCD for display. The sensor is tested for five different samples based on variations of size, density, and grain ability to keep water i.e. paddy, rice, mung bean, corn, and soybeans. The device is tested for all samples with varied moisture content of 11%-32% of corn, 9%-26% of paddy, 14%-40% of mung bean, 10%-28% of rice, and 20%-48% of soybean. The result shows that the device provides good response to the sample. By using linearly regression, it can estimate the grain moisture content with standard error of less than 1%.

Corporate longevity is an interesting issue from a theoretical point of view. In today's uncertain economic climate, the first priority for a company is survival. The longevity of an organization is basically one of the areas that can classify the sustainability of a company. Known as the cultural heritage of Indonesia, the traditional herbal medicine industry faces challenges of longevity. The word Jamu is a generic expression for traditional herbal medicine in Indonesia. The Jamu industry as Indonesia's cultural heritage must be preserved with good support from a technical, regulatory, and commercial perspective so that Jamu companies do not go into the decline stage. Operational resilience is usually defined as the ability of an organization to adapt rapidly to changing environments. This study aims to identify the effect of operational resilience and human capital on corporate sustainable longevity through innovation performance. The questions are addressed through empirical research of 108 small companies that produce Jamu, traditional herbal medicine in Java, Indonesia. This study was conducted during July-September 2020. Data analysis is carried out with SEM-PLS using SmartPLS software version 3.0 to evaluate the data collected. The results indicated that operational resilience influences corporate sustainable longevity directly and indirectly through innovation performance. However, human capital could not play the antecedent role to corporate sustainable longevity directly or even indirectly through innovation performance. Human capital indicators require deeper exposure in the context of small industries.
