Abstract

The study aims to see the effect of using WhatsApp on science learning outcomes at SDN Duri Kepa 03, using a survey method that distributes questionnaires via google form. The problem in this study is that students are required to use online learning methods at home and use their cellphones at all times, because most teachers send course materials and assignments through WhatsApp groups. The use of WhatsApp media also supports the elderly's economy, because at SDN Duri Kepa 03 most of them are from the lower middle class. In science learning, if you only rely on WhatsApp both in the process and the results are not optimal, because in science learning it discusses natural phenomena and the surrounding environment. The results of the partial test obtained tcount = 9.402 > ttable = 2.042. The result is H1 is accepted, which means that there is an influence with a coefficient of determination of 74.7%, the remaining 25.3% is influenced by other factors.

Abstract

Bangka Belitung Island has alot of degraded lands due to tin mining activities. Because the people do not use those for farming, the lands will be the places for unconventional mining continuously. Based on this situation, the researcher did some extension activities and tarinings which aimed to introduce LEISA technology to the farmers in the period of June-Desember 2009 in Kace Village, Mendo Barat Subdistrict, Bangka Regency. The results indicated that 73.81% of the participants strongly agreed and nobody disagreed to the implementation of LEISA in post-tin mining land. the percentage of public confidence to the success of LEISA program in increasing the farmers’ income was about 24.39% for the confidence level >81% and 36.59% for 61-80% of the confidence level. SWOT analysis showed  that government and security officials needed to guarantee the safety and the legal certainlyof agricultural development in post-tin mining land, and also needed to be a partnership among the farmers,  institutions, relevant organizations and government to help the fulfillment of the material and means of agricultural production that can not be supplied by the people independently.

Abstract

BackgroundAnemia is a frequent complication of chronic kidney disease (CKD). Anemia in CKD is associated with reduced quality of life, increased cardiovascular disease, cognitive impairment, and mortality. Therefore it is necessary to find an alternative agent for preventing anemia in CKD. Celery is one of the natural substances that have anti-inflammatory, antioxidant, and antihypertensive pharmacological effects. Based on the mechanism of CKD and its progression, celery is thought to prevent anemia in CKD. This research was aimed at evaluating the protective effect of celery extract against anemia in a CKD rat model. MethodsThis was an experimental laboratory study using 25 male Sprague Dawley rats, aged 2-3 months, they were randomized into 5 groups, namely group A, sham operation; group B, subtotal nephrectomy; group C, D, E, subtotal nephrectomy + 250, 500, 1000 mg/kg BW ethanol extract of celery, respectively. The administration of celery extract was performed 14 days before and 14 days after induction of 5/6 subtotal nephrectomy. The hematological parameters (Hb, RBC, Ht, MCV, MCH, MCHC) and serum creatinine level were measured at the end of the study. Data were analyzed with One Way ANOVA and Kruskal-Wallis test followed by Mann-Whitney test at p<0.05. ResultsThere were no significant differences between groups in Hb, RBC, Ht, MCV (p>0.05) and significant differences between groups in MCH and MCHC (p<0.05). The highest levels of Hb, RBC, and Ht were found in group C.ConclusionCelery ethanol extract at a dose of 250 mg/kg BW/day may prevent anemia in the CKD rat model.
