Abstract

Pemanfaatan dan pengembangan buah belimbing wuluh belum dilakukan secara optimal, karena nilai jual buah yang masih rendah dan tidak diimbangi dengan potensi yang dimiliki buah belimbing wuluh. Beberapa cara pengolahan yang dapat memperpanjang masa simpan belimbing wuluh segar adalah manisan belimbing wuluh. Selama ini masyarakat di Gampong Cucum Kecamatan Kuta Baro hanya mengolah belimbing wuluh tersebut untuk dijadikan asam sunti saja. Oleh karena itu perlu dilakukan diseminasi mengenai produk olahan lain yang berbahan baku dari belimbing wuluh, jika tidak maka dapat dipastikan buah belimbing tersebut akan terbuang sia-sia. Kegiatan ini bertujuan untuk menghasilkan produk yang bernilai ekonomis tinggi karena proses produksinya menggunakan teknologi yang dapat digunakan langsung oleh masyarakat seperti mengatasi permasalahan pengolahan belimbing wuluh segar menjadi produk yang memiliki masa simpan relatif lama. Selain itu, meningkatkan pengetahuan dan minat masyarakat Gampong Cucum dalam memproduksi manisan belimbing wuluh yang bermutu dan mempunyai harga tinggi di pasaran yang pada akhirnya akan dapat meningkatkan taraf hidup masyarakat di Gampong Cucum serta terrciptanya home industry berbahan baku belimbing wuluh.

Abstract

The purpose of this study was to evaluate the performance of Hohenheim Aceh type solar tunnel dryer with the application of proportional integral derivative (PID) controller for outlet fans. The instrumentations used were solar tunnel dryer type Hohenheim Aceh, HTC-meter, anemometer, pyranometer, and other supporting equipments. The results showed that during the drying process solar irradiation had fluctuated, where the average solar irradiation was 649 W/m2. The average temperature in the drying chamber is 40.6°C while the average temperature in the environment is 32.9°C. Conditions in the drying chamber were suitable for drying because the temperature inside the dryer was relatively higher than the ambient temperature. The average relative humidity (RH) in the drying chamber was 36% and the average RH in the environment was about 40%. The relationship between temperature and RH value was negative and strong indicated bu r-value of 0.7379. On the other hand, the relationship between solar irradiation and temperature was positive and also strong indicating that the energy source for this dryer was from solar irradiation with an R-square of 86.02% and r-value of 0.92747. The application of PID controller had improved the performance of Hohenheim Aceh type solar tunnel dryer by preventing the incident of unproper drying temperature. However, the airflow in the drying chamber was too low thus the further engineering design is needed to improve the drying system.

Abstract

Ground roasted coconut is used as a cooking spice, especially in Aceh, with distinctive aroma and fragrant taste. This study aimed to examine the effect of drying time and roasting time on the sensory and physicochemical characteristics of roasted coconut. This research was designed with two treatment factors in triplicate. First factor was the drying time (1, 3, and 5 h), and second factor was roasting time (5 and 10 min). The results showed that drying time has a significant effect on the aroma, color, taste, and air content. The longer the drying time, the higher the sensory characteristics: aroma, color, and taste of ground roasted coconut, but the percentage of water content of the roasted coconut produced is lower. The roasting time also affected the taste and aroma of ground roasted coconut. The longer the roasting process, the higher the sensory characteristics of the taste and aroma of ground roasted coconut. The interaction of drying time and roasting time only has an effect on the sensory taste of ground roasted coconut. Drying time and roasting time did not significantly affectted on fat content and free fatty acid content, both of these parameters are more influenced by other factors, such as drying temperature, harvest age and coconut quality.

Abstract

Pulmonary TB cases in Indonesia are the second highest in the world. The incidence of Anemia in pulmonary TB patients can be as high as 90%. Anemia can lead to poor outcomes in the recovery of pulmonary TB. Songgak coffee is a coffee with a mixture of spices that is commonly consumed by the people of Central Lombok to make the body healthy and increase vitality, including pulmonary TB patients. Songgak coffee is made from 7 types of spices mixed with coffee. The results of previous research show that Songgak coffee has quite good antioxidant content and is an immunostimulant. Antioxidants may increase Hemoglobin levels. This was a case-control study. A total of 26 new pulmonary TB patients were divided into 2 groups. Group A received songgak coffee as an additional anti-TB drug, while group B received anti-TB drug therapy alone. Hemoglobin levels in groups A and B were measured before drug administration and 14 days after treatment. The data collected were nominal data, reported as increasing and non-increasing. A total of 12 out of 13 patients in group A had an increase in Hemoglobin, while only 1 person in group B had an increase in Hemoglobin. The odds ratio value for increasing Hemoglobin levels in pulmonary TB patients who consume songgak is 12. The odds ratio value for increasing Hemoglobin in pulmonary TB patients taking songgak is 12. The odds ratio value for increasing Hemoglobin levels in pulmonary TB patients who take Songgak is 12 times higher than in pulmonary TB patients who do not take Songgak.
