Phytoplankton Changes in Some Inland Water Habitat of Central Kalimantan, Indonesia

The changes in the density, number of genera, diversity index of phytoplankton in some oxbow lakes (LakeRengas, Lutan,Takapan) and lowland lake (Lake Sembuluh) are described.Phytoplankton samples collected in rainy season, dry season (1995 to 1997) and in the forest fire period (October 1997).Before forest fire period, most of the time the density of phytoplankton was high (489 to 759 individuals/1) in January or rainy season especially in oxbow lake system. The high number of phytoplankton in rainy season is not common in the standing water in the floodplain system. This is probably because of the type of water that is acid water with the pH (4.43 to 4.66) in Lake Rengas, Lake Lutan (4.93 to 5.93) and Lake Takapan (4.03 to 4.64).In acid water oxbow lake, only some certain species occurred in the dry season. In January (rainy season),the inputs of water from main river increase the pH and presumably also nutrient, as shown by higher conductivity.In Lake Rengas, the highest density found in June that dominated by one genera (Oocystis).These facts probably because of phytoplankton input from the river Rungan that also show high density of the same species.It is also showed that the number the number of genera is also high in rainy season. Nonetheless of index diversity changes is not clear. In October 1997, when the forest fire period the density of phytoplankton and some genera as a group of Euglenophyceae increased.The highest density was found in Lake Sembuluh that range from 10,507 to 39,536 individuals/1.The phytoplankton density of Lake Rengas, Lutan and Takapan are 3,254, 1,414 and 9,019 respectively.The relationship of forest fire to the phytoplankton density is briefly discussed

Seleksi Induk Kambing Boerawa Grade 1 dan 2 Berdasarkan Nilai Most Probable Producing Ability Bobot Anak Umur Enam Bulan

The aim of this research was to compare MPPA value for 6 months body weight (6 MBW) of 30 heads Boerawa grade 1 (BG1) and 30 heads Boerawa grade 2 (BG2) does and to determine ten heads of the best BG2 does as replacement stock. Research was conducted by survey method at Karya Makmur-1, Karya Makmur-II, and Pelita Karya-III goat farmer groups located at Wonoharjo village, Sumberejo subregency, Tanggamus regency, Lampung province. Sample observed was selected by purposive sampling. Variables observed were 6 MBW of offspring group of BG1 does and BG2 does at the first and second parity. The variables was analysed to know repeatability value and MPPA value for 6 MBW. Repeatability value were estimated by interclass correlation method, MPPA value of BG1 and BG2 was analysed by t student test. Result of this research indicated 6 MBW of offspring group of BG1 does (20.57 ± 1.12 kg) was not different (P>0.05) with the offspring group of BG2 does (22.70 ± 1.06 kg), repeatability value of BG1 and BG2 were 0.29 and 0.33, respectively, MPPA value of BG1 (20.57 kg) were not different (P>0,05) with BG2 (22.70 kg). It could be concluded that genetic potency of BG1 does and BG2 does was not different and the best ten BG2 does were JJ2 (MPPA 23.49 kg), DD3 (23.42 kg), LL1 (23.40 kg), JJ1 (23.32 kg), BB3 (23.29 kg), GG1 (23.27 kg), AA1 (23.14 kg), EE2 (23.08 kg), AA2 (2.05 kg), and GG2 (23.05 kg).

Pola Reproduksi Beberapa Jenis Cyprinidae Di Perairan Lebak Lebung, Lubuk Lampan, Sumatera Selatan

D.I. HARTOTO, SULASTRI & I. RACHMATIKA. 1985. Reproductive pattern of some Cyprinids species at Lebak Lebung flood plain area,Lubuk Lampan, South Sumatera. Berita Biologi 3(3): 128 - 135. -A study on reproductive characteristics of three Cyprinids species was conducted in Lubuk Lumpam; a floodplain area in South Sumatera during the early rainy season of 1981. A study of fecundity supported by other biological aspects was used as an approach to reveal the reproductive pattern. Analysis of the Osteochilus hasselti showed that the fish was an early and multiple spawner that strats to breed in a submerged vegetation habitat type before the peak of food abundance in the rainy season. All of the species could not be grouped as small brood spawners, including the least fecund fish Rasbora lateristriata that spawns late in its life span. Chela oxygasteroides showed a similar pattern to the two other species except that it was predicted to spawn during the time of food abundance. Based on Horn\u27s diagram, recapitulation analysis on factors of reproductive strategy indicated that three Cyprinids could be grouped as r - strategist

Penggunaan Learning Cycle Untuk Meremediasi Miskonsepsi Siswa Pada Materi Tekanan Zat Cair Di SMP

This study aims to find out the effectiveness of Learning Cycle Model in remediating students' misconception for Grade VIII students of SMP Muhammadiyah 2 Pontianak in the topic about Liquid Pressure. The method used is pre-experimental with one group pretest posttest design. The data collecting instrument was a multiple choice test without explanation, which was tested to 29 students sampled by using intact group. The result shows that the students' average misconceptions in the pretest and posttest are 63,18% and 24,13% respectively. Mc Nemar test obtained X2table (3,84) bigger than X2 count for dk = 1 and α = 5%, therefore, overall there is a significant conceptual improvement and the proportion value of the decreasing number of misconceptions is 0,62 (moderate). As the result, remediation by using the Learning Cycle Model is effective to decrease the number of students' misconceptions. This study is expected to be used as an alternative way of implementing remediation to the students' misconceptions on liquid pressure

Kontribusi Kompensasi Dan Motivasi Mengajar Terhadap Kinerja Mengajar Guru

The study objective was to determine the contribution of compensation and motivation to teach the teaching performance of teachers in Public Elementary School. The method used is descriptive analysis, associative and comparative quantitative approach, through correlational data analysis techniques using parametric statistics. 157 sample was divided into two categories of 97 certified teachers and 60 non-certified teachers. From the analysis of the data found that the compensation and motivation of teachers to teach in Primary School in both categories, while the teaching performance of teachers in public elementary school in the category of very good. Compensation contributed to the teacher\u27s teaching performance is strong enough for teacher certification and non-certified teachers. Contribution of motivation to teach teachers to teach to the performance strong enough for teacher certification and lower for non-certified teachers. Contribution of compensation and motivation to teach the teaching performance of teachers is strong enough for teacher certification and non-certified teachers. And there are differences in compensation, motivation, teaching and teachers\u27 teaching performance between teacher certification and non-certification
