Pennahia anea is among of the demersal fish landed at Asemdoyong Fish Auction Centre, Pemalang. P. anea doesn't show sexual dimorphism, so that other characters are needed to differentiate male and female individuals, i.e. truss morphometric and meristic characters. Previous studies have shown that truss morphometric and meristic can differentiate between male and female individuals. This study aims to describe the morphometric and meristic truss characters and determine the truss morphometrically and meristic characters that distinguish between males and females of Pennahia anea. The research used a survey method with a purposive random sampling technique. Male and female individuals of P. anea were examined based on their meristic and truss morphometric characters. The data were analyzed statistically using Mann Whitney non-parametric test. The result proved that male and female were significantly different in seven out of the 31 truss distances. Male individuals had a larger size than female individuals in three truss distances. In contrast, the male had a smaller size than the female individuals in four out of seven truss distances that distinguish both sexualities. The soft fin radius of the ventral fin was significantly different between male and female of P. anea. It could be concluded that male and female individuals of Pennahia anea have different truss distances and meristic characters with seven truss distances and one meristic character are different

The level of physical condition can directly affect the team's success in winning the match. The purpose of this study is to implement sport-specific test and measurement related to basketball to investigate the level of fitness for basketball athletes in Central Java highschool basketball team (PPLOP). The total of 13 athletes were signed for this study. Methods used to collect data were test and measurement containing of the following 60-m sprint test, sprint fatigue test, maximum push up, one minute push up, beep test and V-sit. These are sequentially intended to measure speed, anaerobic endurance, upper extremity muscular endurance, abdominal muscular endurance, aerobic endurance, and flexibility. In addition, a different test was conducted using ANOVA technique to determine differences in physical conditions between starters and reserve players. The results suggested that generally the level of physical condition of PPLOP players is in good condition. However, the muscular endurance of the arms and shoulders requires an increase because the results are categorized as less. The significant difference in physical capacity between starters and reserve players was recorded only in the number of push ups (p <0.05) recorded. This research can be used as a reference for trainers in creating training programs and adopting the types of tests and measurements selected in this study as guidelines for physical measurement for basketball athletes.

Banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is known as vector of Banana bunchy top virus (BBTV) that threatening production of banana worldwide. It was reported recently that P. nigronervosa and P. caladii is “cryptic species”. A good and proper identification is necessary to verify the correct species and its status. Research was conducted to identify and to find the host range of banana aphids in Java. Aphid collection was conducted in several locations in West Java, Central Java, and East Java. Eleven morphometric characters were analyzed to assess the morphometric variations among banana aphids. Morphological identification and principle component analysis (PCA) approach were conducted for accurate identification of banana aphids. Two species of aphids were found during the survey in Java, i.e. P. nigronervosa and P. caladii. P. nigronervosa mostly infested bananas (Musa spp.), and a few was found on heliconia (Heliconia sp.) and banana traveler (Ravenala madagascariensis). In contrast, P. caladii generally infested taro (Colocasia esculenta), turmeric (Curcuma longa), costus (Costus sp.), dumbcane (Dieffenbachia sp.), but rarely on bananas.
