Natrium pentagamavunonat-0 merupakan bentuk garam dari senyawa pentagamavunon (PGV-0). Modifikasi PGV-0 menjadi bentuk garam dimaksudkan untuk meningkatkan kelarutannya. Pada penelitian ini, natrium PGV-0 diuji pengaruhnya terhadap kontraksi otot polos aorta terisolasi yang diinduksi agonis reseptor a1 adrenergik, yaitu fenilefrin. Disamping itu, natrium PGV-0 juga dipelajari efek relaksasi pada organ tersebut. Hasil penelitian menunjukkan bahwa natrium PGV-0 menghambat kontraksi otot polos aorta tikus secara bermakna. Senyawa tersebut dapat menurunkan baik harga pD2 maupun efek maksimum dari fenilefrin. Disampimg itu, natrium PGV-0 menunjukkan efek relaksasi yang poten pada organ tersebut, dengan nilai pD2 sebesar 4,41. Berdasarkan hasil tersebut disimpulkan bahwa natrium PGV-0 menunjukkan efek yang poten pada otot polos aorta terisolasi yang diinduksi agonis reseptor a1 adrenergik. ABSTRACT PGV-0 is reported possessing some pharmacological effects such as anti-cancer, anti-allergy, anti-inflammatory, anti-oxidative etc. Its effects are more potent than curcumin. However, this compound has limitation in its solubility. Modifying the compound to its salt form is supposed to overcome this problem. The aim of the research is to investigate the effects of PGV-0 sodium on rat isolated-aortic smooth muscle contraction, and its relaxant effect on the tissue. The study was conducted using an isolated organ technique with an isotonic transducer. The percentage of response either contraction or relaxation was then plotted as a logaritmic scale of concentration-response curve to calculate pD2 value, a negative logaritmic of concentration of drug inducing 50% of maximum effect. The results have shown that treatment of PGV-0 sodium obviously inhibited the contraction of rat isolated-aortic smooth muscle induced by phenylephrine. The compound could decrease both pD2 and Emax values of phenylephrine significantly. The results indicate that PGV-0 sodium could attenuate both potency and intrinsic activity of contraction effect of phephylephrine. Besides, the compound also stimulated relaxant effects to a single phenylephrine contraction with pD2 value of 4.41. The compound could restore phenylephrine-induced tension into baseline level. Based on the results, PGV-0 sodium showed potent effects on rat isolated-aortic smooth muscle.

Kata kunci— Desa Senggreng, Waduk Karangkates, olahan ikan mujair, ekonomi desa Abstract Senggreng Village in Sumberpucung Subdistrict, Malang Regency is a village that has a very beautiful natural scenery, namely the existence of a reservoir that is fed by the Berantas Karangkates River and this is a natural tourism potential that has been visited by many people. In the village of Senggreng it also has local potential in the form of tilapia fish which are very numerous and by the community are only managed by selling them raw. The relatively inexpensive price is less able to provide significant benefits to the community so innovation is needed to process it further. Seeing this kind of situation, it is necessary to hold training on processing nuggets and crackers based on tilapia fish. The objectives of carrying out these activities include: 1) as an effort to develop food based on tilapia fish; 2) as a driving force for the establishment of a unique souvenir center in Senggreng Village; 3) and as an effort to improve the economy of the villagers. Overall the activities went smoothly and the community had new knowledge and skills in processing tilapia fish into high economic value products.

As a maritime country with a large area, besides the need to defend itself with the military, it also needs to protect itself with aerospace technology that can be controlled automatically. This research aims to develop an air defense system that can control guided missiles automatically with high accuracy. The right method can provide a high level of accuracy in controlling missiles to the targeted object. With the backpropagation neural network method for optimal control output feedback, it can process information data from the radar to control missile’s movement with a high degree of accuracy. The controller uses optimal control output feedback, which is equipped with a lock system and utilizes an accelerometer that can detect the slope of the missile and a gyroscope that can detect the slope between the target direction of the missile to follow the target, control the position, and direction of the missile. The target speed of movement can be easily identified and followed by the missile through the lock system. Sampling data comes from signals generated by radars located in defense areas and from missiles. Each part’s data processing speed is calculated using a fast algorithm that is reliable and has a level of accuracy and fast processing. Data processing impacts on the accuracy of missile movements on any change in the position and motion of targets and target speed. Improved maneuvering accuracy in the first training system can detect 1000 files with a load of 273, while in the last training, the system can detect 1000 files without a load period. So the missile can be guided to hit the target without obstacles when maneuvering.
