Gamma ray mutative induction for increasing genetic variation has been applied for plant prime variety engineering. The materials are derrived from seed organ, shoot and calli. Calli is a group of actively dividing cell and have not been organized to form plant. The benefit of using calli explant is that the gamma ray could directly shot to DNA in the nuclear cell in such a way that there is higher opportunity for genetic change to occur. The problema of using calli explant are the difficulties in regenerating the calli into shoots, due to the deformation as a result of radiation process. Therefore, this research is aimed at obtaining the appropriate media formulation for shoot regeneration from Fatmawati-rice calli which has been irradiated with gamma ray. The reseach was conducted in BB-Biogen laboratory consisting of three experiments, such as : (1) calli iradiation with the dosage of 0; 5; 10; 15; 20; 25; 30; 35; 40; 45; 50; 55 and 60 Gy, (2) shoot regeneration at the MS + BA (0, 1, dan 3 mg/l) + IAA (0 dan 0,8 mg/l) media, and BA (0, 1, and 3 mg/l) + zeatin ( 0; 0,1; 0,2 and 0,3 mg/l) + IAA 0,8 mg/l and (3) Shoot induction at MS + IBA (0, 1, 2 and 3 mg/l) media. The result shows that the range of LD50 was obtained at the dosage of 30 Gy, the most apropriate media for shoot regeneration is MS + BA 3 mg/l + IAA 0,8 + zeatin 0,1 mg/l and media for root induction is IBA 1 mg/l.

In vitro culture can be applied for producing new genotype which is tolerant to biotic and abiotic or to incerase secondary metabolic content. To obtain the optimum result of variety improvement, regeneration system should firstly be found out.It is sufficiently difficult to regenerate pulai pandak (Rauwolfia serpentina L.). Hence, with this system, the improvement of R. serpentina with secondary metabolic content higher than the other. The mother stok of R. serpentina used in this experiment, belongs to the collection of BB-Biogen. Calli were produced from leaves and internodes which is cultured at medium MS contain 2.4-D (0, 1, 3,5, 7 mg/1) combined with caseine hydrolysate 3 mg/1. Regeneration medium was MS contain BA (0,5, 1 mg/1) combined with zeatin (0, 0.1 and 0.5 mg/1) and root formation used was three kinds of auxin (IBA, IAA and NAA). The result showed that inter nodels was better that leaves to callus induction. In this experiment, MS + 2,4-D 1 mg/1 + CH 3 mg/1 was the best medium to induct calli,while medium MS + BA 1 mg/1 + Zeatin 0,5 mg/1 + maltosa 3% to regenerate and MS + IBA lmg/1 for root induction.

A total of 21 aquatic plant species were collected from Bantimurung waterfall areas, South Sulawesi, Indonesia, in October 2017. These plant materials were subjected to both species and phytochemicals identification. The aims of this study were to determine the species or taxonomic rank of Indonesian aquatic plants collected from Bantimurung waterfall, South Sulawesi, Indonesia and to identify their chemical compounds (phytochemicals) as a candidate for new herbal medicine. Plant genetic materials used in this study were collected from Bantimurung Bulusaraung waterfall and were then identified based on standard botanical techniques for species identification in the Herbarium Bogoriense, Research center for Biology Indonesian Institute of Science (LIPI), Cibinong, West Java. The samples were subjected to the phytochemistry screening such as alkaloids, flavonoids, tannins, saponins, glycosides, terpenoids and anthraquinone followed the procedures of Indonesian Materia Medika and Harborne. Results showed that all collected aquatic plant samples were able to be identified, including their species names. Phytochemical screening of each sample revealed the presence of glycoside in all of the tested species. However, no alkaloids, anthraquinones, and terpenoids were observed in those tested plant samples. Of the total 21 aquatic plants, 14 species contained flavonoids, 8 species contained phenol compound, and 10 species contained saponins. Among these species Donnax canniformis possessed good antioxidant activity, which correlated to its total phenolic and flavonoid contents. Our results would be beneficial for any future effort in the development of new herbal drugs derived from aquatic plants.

This study was aimed to identify the potential use of active compounds extracted from Staurogyne sp as an antibacterial agent to control disease-causing bacteria in fish. Staurogyne sp, an aquatic plant collected from Bantimurung, South Sulawesi were subjected to allelochemical compound. Plant extracts were tested to five bacteria including four types of bacterial pathogen, such as Aeromonas hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, and Flavobacterium columnare, and one bacterial sensing quoroum, Chromobacterium violaceum. Based on phytochemical analysis, Staurogyne’s extracts derived from both stem and root contained flavonoids, phenols, and antioxidants compounds with the concentration of 0.018 mgQE/g, 0.3471 mgGAE/g, and 1004,391 IC50 µg/mL, respectively. In addition, Staurogyne plant extracts derived from both their stem and root has also produced both saponins and glycosides compounds. Plant extracts derived from Staurogyne’s leaves revealed three major chemical compounds such as flavonoids (0.77 mgQE/g), phenol (0.0629 mgGAE/g), and glycosides (+). However, no antioxidants and saponin compounds were detected. Applying plant extracts as an antibacterial on five disease-causing bacteria causing diseases in aquaculture, such as Aeromonas Hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, Flavobacterium columnare, and Chromobacterium violaceum bacterials revealed that at concentration of 0.1 g the Staurogyne sp extracts did not influence all the bacterials growth. However, by application of plant extract at concentration of 0.2 g on the growth media,three out of 5 tested bacterials (Aeromonas hydrophilla, Edwardsiella ictaluri, and Streptococcus agalactiae) showed intermediate inhibition responses on bacterial growth. The growth of remaining two bacterials pathogen, Flavobacterium columnare and Chromobacterium violaceum at 0.2 g plant extract of Staurogyne sp was not affected. This study revealed that the use of active compound derived from Staurogyne sp would be potential to be used in inhibiting disease-causing bacterial in fish in future. However, optimum concentration of the plant extracts, in particular on the inhibition of the growth of disease-causing bacteria in fish is still needed to adjust.Key words: Antibacterial, aquatic plant, Staurogyne sp, fish disease

When children enter the education stage in secondary school, that is when children enter adolescence where they are looking for their identity by trying new things that they have not encountered before. At this stage the school environment will further develop their thinking patterns and further expand the child's social life. Low self-esteem in students results in them not believing that they are able to do what their parents and teachers expect of them. Low self-esteem, showing avoidant behavior. This study aims to explore the relationship between self-esteem and academic achievement among high school students in Muara Teweh. During adolescence, the school environment and self-esteem play crucial roles in shaping students' identities and academic performance. Previous research has highlighted that low self-esteem can hinder optimal academic achievement. Through a survey of 60 high school students, data were collected using questionnaires to measure self-esteem and academic performance. The results indicate a relationship between self-esteem and academic achievement, although the correlation between them tends to be weak. These findings underscore the importance of attention to both variables in the educational context. Schools and educational communities are encouraged to pay attention to the complex dynamics between self-esteem and academic achievement to create a supportive learning environment for students' development. Students are also encouraged to strengthen their self-confidence in understanding subject matter and taking on new challenges. The implication of this research is that it can be a learning medium and consideration in making policies in the field of education. It is necessary to pay attention to the contribution of other variables in supporting and encouraging student academic achievement at school, such as self-efficacy variables and student learning independence.Saat anak memasuki tahap pendidikan di sekolah menengah, saat itulah anak memasuki masa remaja dimana mereka sedang mencari jati dirinya dengan mencoba hal-hal baru yang belum ditemui sebelumnya. Pada tahap ini lingkungan sekolah akan lebih mengembangkan pola pikir mereka dan lebih memperluas kehidupan sosial anak. Rendahnya self esteem pada diri siswa/i mengakibatkan mereka tidak percaya bahwa mereka mampu melakukan apa yang diharapkan orangtua dan guru kepada mereka. Rendahnya self esteem, memperlihatkan perilaku menghindar. Penelitian ini bertujuan untuk mengeksplorasi hubungan antara self-esteem dan prestasi belajar siswa SMA di Muara Teweh. Dalam tahap remaja, lingkungan sekolah dan kepuasan harga diri memainkan peran penting dalam pembentukan identitas diri dan prestasi belajar siswa. Penelitian sebelumnya menyoroti bahwa self-esteem yang rendah dapat menjadi hambatan dalam pencapaian prestasi belajar yang optimal. Melalui survei terhadap 60 siswa SMA, data dikumpulkan menggunakan angket untuk mengukur self-esteem dan prestasi belajar. Hasil menunjukkan adanya hubungan antara self-esteem dan prestasi belajar, meskipun korelasi antara keduanya cenderung lemah. Temuan ini menggarisbawahi pentingnya perhatian terhadap kedua variabel ini dalam konteks pendidikan. Sekolah dan komunitas pendidikan diharapkan dapat memperhatikan dinamika kompleks antara self-esteem dan prestasi belajar untuk menciptakan lingkungan pendidikan yang mendukung perkembangan siswa. Siswa juga didorong untuk memperkuat keyakinan diri mereka dalam memahami materi pelajaran dan mengambil tantangan baru. Implikasi dari penerlitian ini yaitu dapat menjadi media pembelajaran dan pertimbangan dalam mengambil kebijakan dalam bidang pendidikan. Perlu diperhatikan kontribusi variabel lainnya dalam mendukung dan mendorong prestasi akademik siswa di sekolah seperti variabel self efficacy dan kemandirian belajar pada siswa.

ABSTRACTSouth Sulawesi is known as one of national rice production centers. However, average productivity of rice varieties planted in that area (4.43 ton ha-1) is lower than those of rice productivity in Java (5.25 ton ha-1). The aims of this research were to evaluate agronomic characters and adaptation of 7 dihaploid mutant advanced lines of new plant type (DH-NPT) of rice at several locations in South Sulawesi. The research was conducted in 2012 at Maros, Gowa, Barru, and Pangkep. The experiments were conducted in randomized complete block design with 3 replications nested in locations. Treatment consisted of 7 DH-NPT of rice, i.e., BIO-MF115, BIO-MF116, BIO-MF125, BIO-MF130, BIO-MF133, BIO-MF151, BIO-MF153, and control varieties i.e., Fatmawati, Ciherang, and Inpari13. The results indicated that in general the lines had medium height (102.77-110.23 cm), moderate productive tiller (9-16 tiller per hill), moderate days to flower (50%), i.e., 73-76 days after sowing (DAS), earlier days to harvest (103-110 DAS), moderate panicle length (28.35-29.31 cm), large number of grain per panicle (> 250 grains) with moderate panicle fertility (63-70%), moderate 1,000 grain weight, i.e., 26.51-27.75 g, and high yield (7.51-8.09 ton ha-1). Four lines, i.e., BIO-MF116, BIO-MF130, BIO-MF151, and BIO-MF153 were stable and had wide adaptability. Other lines, i.e., BIO-MF125 and BIO-MF133 were sensitive to environmental changes, therefore they were classified as specifically adapted to favorable environment; while BIO-MF115 was not sensitive to environmental changes, and therefore it was adapted to non-favorable environment.Keywords: adaptation, agronomic characters, rice mutant
