DEVELOPING WORKSHEETS BASED ON SCIENTIFIC CREATIVITY IN FUNDAMENTAL PHYSICS COURSE
No full textThe goals of this study are to develop worksheets that valid and effective to improve students’ scientific creativity in fundamental physics course. Designs of this development are include preliminary research, prototype phase, and assessment phase. The pilot study of worksheets was carried out by 30 students of Physics Education FKIP at Lambung Mangkurat University Banjarmasin in March to July 2016. Data collected from validation by experts of physics learning, tests, and qualitative descriptive analysis. Data were analyzed by descriptive quantitative and qualitative. Design of worksheets include identity, learning indicators, necessary of creative learning, creatively problem finding, creatively experiment designing, creatively science problem solving, and strengthening scientific creativity. The validation results of worksheets include design, format, content, language, presentation, support innovation and learning quality in a highly valid criterion. It is developed according to the needs and logically arranged by decree of renewal of scientific knowledge. A lot of students' scientific creativity (creatively problem finding, creatively experiment designing, and creatively science problem solving) those have creative criteria/highly creative criteria. And increasing students’ scientific creativity before and after the learning process as many as 57% is in high criteria, 43% are in the middle criteria, and no students in the less criteria. The conclusion is the worksheet that developed in this research, valid and effective to improve students’ scientific creativity in fundamental physics course

No full textEvaluasi Genetik Varietas Padi Lokal Lahan Rawa Pasang Surut Kalimantan Selatan Berdasarkan Karakter Kromosom
No full textGenetic evaluation of germplasm collections is an important foundation for crop improvement. Due to the importance of rice as a major world crop, the deep studies or genetic evaluation of Oryza sativa has attracted great interest. This study was conducted to evaluate the genetic identity of five rice landraces from South Kalimantan’s tidal swamp area based on chromosomal character. The chromosomal study was carried out using a modified squash method. The construction of karyotype was done by following procedure of Levan et al. (1964). Results found that mitosis period of all samples mainly occurred from 12.00 to 13.00 a.m. (WITA-Center Indonesia Time). Prometaphase stages of rice landraces was commonly found at 12.30 a.m. (WITA). Results also found that all of rice landraces have chromosomal numbers of 2n=24 (diploid), with the differences of chromosomal character (karyotype). Adil ganal is the variety that has unique chromosomal character of 23 metacentric and 1 submetacentric (11m+1sm) chromosomes with satellite found on this study. Whereas, Siam Unus and Siam Gadis are the local rice varieties that have primitive chromosome type of 24 metacentric (24m+0). The results of this study would provide valuable information for crop improvement or rice breeding program in future
Analisis Usaha Penangkapan Ikan dan Model Kemitraan Pendidikan Kelautan dengan Masyarakat Nelayan Desa Pagatan Besar Kabupaten Tanah Laut
No full textThis research is aiming to take completely and accurate: (1) information of fisherman fishing activities at Pagatan Besar village, (2) information of fisherman hopes to develop their firm and cooperate figure that they hope, (3) information of Lambung Mangkurat University’s sea education equipments and cooperated figure that it can make with fisherman community, and (4) formulation of partnership sea education model between Lambung Mangkurat University and fisherman community. This research use descrivtive method and feasibility study. The results showed that generally fishing firm at Pagatan Besar village is fishing firm by seasons (gillnet) and along year (bottom seine net). Investment value of gillnet more than investment value of bottom seine net. However, gillnet firm activities was more doing by fisherman of Pagatan Besar village because the activity was give more profit financial to fisherman. That is supporting by NPV analysis result at discount rate 18%, which NPV value of gillnet firm (Rp 172.876.266,81) more than NPV value of purse seine firm (Rp 67.963.946,08). And Gross BCR analysis result showed that Gross BCR value of gillnet firm (1,41) more than Gross BCR value of purse seine (1,27). In the other side, payback period of investment of gillnet firm (2,19 tahun) more long than purse seine firm (1,44 tahun). There is not formal agreement of fishing firm job system by fisherman Pagatan Besar for along time and only based on trusted. So, job relationship between owner and fisherman not formally engaged. Profit of firm was divide by profit divided system (50% profit to owner and 50% to sailorman, and captain was take bonus 10% from owner profit part). Pagatan Besar fisherman was agree to cooperated with university for along time (more than one year) in the legal cooperated and they are agree to evaluated (minimal after three times catch operation). Beside, fisherman become partner of cooperated must have primary criterions: integrity, good track record, and more experience in catch operation and firm management. Sea partnership model between university and fisherman community at Pagatan Besar village is partnership sourcing, where university preparing ship and machine, and capture equipments, and fisherman partner preparing skill and manpower. Costs operational is joint responsibility. Profit divide system will adaptation the rule of profit divide in fisherman community

Kajian Farmakognostik Simplisia Daun Karamunting (Rhodomyrtus tomentosa) Asal Pelaihari Kalimantan Selatan
No full textKaramunting telah lama digunakan oleh masyarakat sebagai obat tradisional. Dilihat dari
prospek yang sangat potensial sebagai bahan obat maka perlu dilakukan kajian
farmakognostik sampel untuk pengendalian mutu dan keaslian simplisia. Penelitian ini
bertujuan memberikan dasar ilmiah mengenai gambaran farmakognostik secara kualitatif dan
kuantitatif. Hasil penelitian secara kualitatif dan kuantitatif telah dideskripsikan. Identifikasi
kimia menunjukkan hasil positif terhadap aleuron, tanin, katekol, alkaloid dan saponin.
Karakteristik farmakognostik secara kuantitatif yaitu kadar abu sebesar 3,1%, kadar abu tidak
larut asam 2,89%, kadar abu larut air 1,69%, susut pengeringan 14%, kadar sari larut air
0,48%, kadar sari larut etanol sebesar 0,36% dan bahan organik asing 0%. Hasil
kromatogram diperoleh senyawa spesifik pada fase gerak kloroform : metanol : butanol (15:
2: 1) dengan nilai Rf 0,72 pada pengamatan dibawah lampu UV254 dan UV366. Pada fase
gerak n-heksana : etil asetat (8 : 2) diperoleh dua senyawa yang spesifik dengan nilai Rf
masing-masing 0,65 dan 0,78 dengan pengamatan dibawah lampu UV254 dan UV366.
