Depression, a mental disorder marked by sadness, anhedonia and increased fatigability, is becoming more common in this industry 4.0 era. Nowadays, depression affects approximately 322 million people around the world (more than 14 million in Indonesia) and gives major contribution to the rise of global burden of disease. Although antidepressant is considered the common treatment for depression, recent studies show a possibility to treat depression by altering gut microbiome of the patient, by giving them probiotic food. Tempeh is a globally well-known Indonesian paraprobiotic food which already proven to modulate gut microbiota. This research aimed to find out the effect of tempeh to depression symptom as expressed in Balb/c mice behaviors. The methods used was to feed tempeh or tempeh starter to mice which were depressed-induced by Unpredictable Chronic Mild Stress (UCMS) procedure. Parameter measured were depression level of the Balb/c mice based on immobility times and grooming durations acquired from tail suspension test, forced swim test, sucrose splash test and coat state score. The result showed that tempeh supplementation did not affect coat states and grooming durations but tend to improve immobility times of the Balb/c mice. Meanwhile, tempeh starter supplementation tends to improve the immobility time and kept coat state clean/tidy, but lowered grooming duration. In conclusion, supplementation of paraprobiotic tempeh, especially in starter form, tend to improve depression symptoms. Keywords: depression, mice, paraprobiotic, tempeh

Post-harvest loss is a process of the loss or the broken material from production in the field to the food being ready to be consumed. Losses in agricultural or horticultural produce are a major problem in the post-harvest process. Therefore, it was needed to identify the criteria based on the post-harvesting process to know the performance level of each criterion provided. This study was aimed to know the post-harvest loss source in the occurrence of the post-harvest process of okra. This research used Objective Matrix method (OMAX) to evaluate the performance level of each criterion provided. AHP method was also implemented in this research by using the pairwise comparison technique to measure the weight on OMAX and fishbone diagram and to identify causes factors of the okra loss. The research result showed that the picking and weighing process during post-harvest okra have lower performance level and it was not meet the expected target of the company (PT Mitratani Dua Tujuh). Other result of okra loss level was also still far from the expected target of the company. The improvement recommendations were needed to reduce post-harvest okra loss, i.e. increasing supervision by the manager, making removal plot during okra harvesting, and briefing every morning with the okra picker. Keywords: AHP, fishbone diagram, OMAX, post-harvest loss

As an authentic food of Palembang people in South Sumatera Province, pempek is famous local food caused of unique color (yellowish-white color), flavor (fishy flavor), and chewy texture. Pempek as semi-wet food that can be dried to decrease water content and increase the shelf life. Dried pempek has a lighter and smaller volume material and making it easier to distribute and expand marketing. Pempek can be prepared from ground fish (cork fish), tapioca flour, salt, and water. These ingredients are mixed to form a dough. Pempek dough can be formed into a small pempek, such as lenjer, pastel, otak-otak, adaan, keriting, and kapal selam. Pempek is generally has a wet form. Wet pempek has a high water content of 50-60%, so it had shelf life about 3-4 days. Therefore, wet pempek must be dried to make it long shelf life. The aim of the research was to know about small dried pempek lenjer characteristic based on various addition of CaCl2. The treatment of various CaCl2 concentrations has a very significant effect on water content and protein content (chemical value) and significantly influence the organoleptic properties (aroma, color, and taste) of the dried pempek lenjer. The 1.5% concentration of CaCl2 (C3) treatment has the highest average level of likeness on aroma 3.75, color 3.90, and taste 3.95 with preferred criteria on a dried pempek lenjer. Keywords: chemical, organoleptic, small dried pempek lenjer
