Abstract

 Artocarpus integer (Thunb.) Merr. (Cempedak) is a plant with a kind of Moraceae family that is widely cultivated in Luwu, South Sulawesi. Extraction and antibacterial bioactivity test of Artocarpus integer (Thunb.) Merr. Heartwood have been done. Preparation of heartwood conducted by shaved, dried, crushed and macerated with methanol to obtain a crude extract of methanol. The methanol extract then partitioned successively in n-hexane, chloroform and ethyl acetate to obtain the fraction of n-hexane, chloroform, ethyl acetate, and methanol. Antibacterial activity test using agar diffusion method on two types of gram-negative bacteria (E. coli and S. typhi) and two types of gram-positive bacteria (S. aureus and S. pneumonia) has been performed. The inhibition zone obtained on each fraction are the n-hexane fraction of 12.80 mm in the bacterium S. pneumonia, chloroform fractions of 13.80 mm in the bacterium S. pneumoniae, ethyl acetate fraction of 9.80 mm in bacteria    S. typhi, and the methanol fraction at 12.90 on S. pneumonia bacteria. The chloroform fraction has potential as antibacterial caused by the highest of inhibition ability toward S. pneumonia. Keywords: Antibacterial activity, Artocarpus integer (Thunb.)

Abstract

The direction of development in Indonesia has strongly integrated with the concept of good governance started from the strengthening of international market that is both imperialist and colony thereby contradicting to the tradition of developing countries. This leads to the establishment of sound governance as an alternative concept to improve the government's capacity to innovate in policy and administration. The development of Mamminasata Metropolitan area in South Sulawesi province experiences difficulties in implementing the coordination, integration, synchronization and cannot accommodate the whole event in order to realize the interconnection of development across districts / cities, whereas the central government makes this as a National Strategic Areas (KSN) and leading area in the East Indonesia. This study aims to explore and analyze the sound governance practices in the development program of Mamminasata Metropolitan area focusing on five dimensions, namely process, structure, values, management, and policy. The results show that 1) in the process dimension, the stakeholders involved in the Mamminasata development program establish inter-regional cooperation and coordinate externally and internally of the area ranging from planning to the implementation of development activities; 2) in the structure dimension, the government has established clear organization and regulation in regulating the development process. 3) in the value dimension, Mamminasata development program is based on the responsiveness of local government and has up-holded justice in accordance with the potential of each area; 4) in the management dimension, the government personnel has already had knowledge about the Mamminasata concept, but they are still experiencing problems in the use of technology because of limited resources; and 5) in the policy dimension, the government has encouraged the public to participate directly in policy making and implementation of development programs. Therefore, it can be concluded that the five dimensions of sound governance has been practiced in the Mamminasata Metropolitan area development.

Abstract

This study used S. polycystum and T. deccurens were extracted with various solvents (n-hexane, ethyl acetate and ethanol) to determine phytochemical screening and antioxidant activities. Extraction of samples by maceration method, antioxidant activity assay using the immersion method of DPPH (1,1-Diphenyl-2-picryl Hidrazil) measured absorption at a wavelength of 515 nm and compared with the control of antioxidant vitamin C. The results showed that antioxidant activity of the methanol, ethyl acetate, n-hexane extract of S. polycystum have low antioxidant activity with the value IC50 340,06, 180,54, and 502,25 mg/mL. Methanol, ethyl acetate, n-hexane extracts of  T. deccurens have low antioxidant activity with value IC50 491,02, 411,80, and 502,7 mg/mL. This potential is lower than vitamin C IC50 value of 1,72 mg/mL.

Abstract

The 4-hydroxycinnamamide  is a compound  that has been isolated from the root bark of Kleinhovia hospita Linn. The compound show high toxicity to Artemia salina Leach (IC 180,53 µg) so it can be expected has cytostatic activity against P388 leukemic cells. However, the concentration of the compound in the root bark of K. hospita Linn is very low (about 1.6 ppm), and commercially the compound  is  not  ready  and  has  never  been  synthesized.  Therefore,  it  is  important  to  find  out  a synthesis method to used in prepare the compound for further examination, in particular its cytostatic activity. By this research, the 4-hydroxycinnamamide compound has been prepared from 4- hydroxycinnamic  acid  via  esterification  reaction  with  excess  ethanol  and  sulphate  acid  catalyst followed  ammonolysis  reaction  with concentrated  ammonia.  The esterification  stage  gave  ethyl 4-hidroxycinnamate   as  white  crystall  with  melting  point  133-134oC   and  34.9%  yield,  and  the ammonolysis stage gave 4-hydroxycinnamamide as white crystall with merting point 140oC and 46.1% yield. Identification of the reaction product was carried out by FTIR and NMR spectroscopy methods.Keywords: 4-hydroxycinnamamide, 4-hydroxycinnamic acid, esterification, ammonolysis

Abstract

A study on the use of MCM-48-nCaO as a catalyst in the esterification reaction of nyamplung seed oil (Calophyllum inophyllum L.) has been carried out. The characterization results of XRF, XRD and FTIR showed the success in the synthesis of heterogeneous catalysts, MCM-48- nCaO, using a grinding-impregnation method. Through esterification reaction using the catalysts, FFA content in the seed oil of nyamplung reduced from 28 to 1.7%.
