Dioscorea pentaphylla L. tubers, locally known as tomboreso tubers by Indonesian people, grow wild in forests in various parts of Indonesia but are not well-underutilized. This article aims to comprehensively review the phytochemistry, nutritional, anti-nutritional, and bioactivity of tomboreso tubers. The method used is a literature study with a database of online articles downloaded from Google Scholar related to the topic discussed. Various earlier studies reported that tomboreso tubers are rich in phytochemical compounds, such as alkaloids, flavonoids, polyphenols, terpenoids, tannins, glycosides, and saponins. Tomboreso tubers are also rich in complete nutritional content, such as protein content (1.69-9.20%), fat (0.14-6.24%), fiber (1.28-7.24%), starch (3.71-61.26%), minerals, amino acids, and fatty acids. Furthermore, tomboreso tubers also contain anti-nutritional compounds that are less beneficial to health, such as tannins, oxalates, hydrogen cyanide, phenols, flavonoids, phytates, a-amylase inhibitors, and trypsin inhibitors. Tomboreso tubers have been shown to have various biological activities, such as anti-bacterial, anti-mutagenic, and antioxidant, from various earlier studies. To make tomboreso tubers safe to eat and an alternative food source with low anti-nutritional content, further research must be done on their exploration, utilization, and further processing to reduce anti-nutritional compounds.

Red snapper (Lutjanus sp) in Brondong waters, Lamongan Regency, is one of the main sources of livelihood for local fishermen. To increase the catch, optimizing the use of fishing gear, including setting time, is important. This study aims to determine the effect of differences in setting time on hand line fishing gear on red snapper catches. The study was conducted using the experimental fishing method, by dividing the setting time of hand line fishing gear into 2 treatments, namely morning 08.00-11.00 and afternoon 15.00-18.00. Based on the T test on paired samples, the average catch at 08.00-11.00 WIB was 2,131 with a total of 34.1 kg, while at 15.00-18.00 WIB, the average catch reached 6.4 with a total of 102.4 kg. The T-test results show that the t-count is greater than the t-table, so the null hypothesis is rejected and it can be concluded that there is a significant difference between the red snapper catches in the two time periods. Red snapper tends to be more active in foraging in the afternoon to evening, in line with its nocturnal nature. Several studies have stated that predatory fish such as red snapper hunt more when the light begins to dim. However, other factors such as food availability and physical conditions of the waters can also affect fish feeding activity. These findings provide additional insight into the feeding behavior of red snapper and the factors that influence its presence in the waters.
