In recent years, the presentation of culture in the form of works through folklore has become less attractive. This research aims to create an interactive book on Lampung folklore that incorporates character values and describes the strengthening of students' character through interactive folklore books incorporate character values. This study employs Borg and Gall's research and development procedure. Data collection methods include direct observation or observation, interviews, questionnaires, focus groups, and a literature review. According to the findings of this study, the construction of scaffolding-based folklore in the Legend of Tulung Naga is quite feasible. It may offer students a thorough grasp of character values. Spiritual qualities, nationalism, independence, and social caring are character traits that can be strengthened after students read the scaffolding-based Lampung folklore b...

Manusia dan semua makhluk hidup membutuhkan air untuk kepentingan lainnya. Ketersediaan air dari segi kualitas maupun kuantitas mutlak diperlukan. Penyediaan air bersih bagi penduduk Kota Ternate khususnya di Kota Ternate selatan seringkali terkendala. Penyebab dari krisis ketersediaan air ini antara lain sumber Existing tidak dapat dioptimalkan karena terbatasnya kapasitas sumber air. Salah satu masalah yang dihadapi ialah bagaimana sistem pengolahan air bersih di IPA Ngade dan berapa besar kuantitas air yang dihasilkan IPA Ngade, tujuan penelitian ini ialah untuk mengetahui sistem pengolahan air bersih di IPA Ngade dan kuantitas air yang dapat dihasil oleh IPA ngade.Penelitian ini dilakukan didanau Laguna di Kelurahan Ngade kawasan kota Ternate, Penelitian ini menggunakan beberapa data Primer diantaranya : data yang didapat dari hasil pengujian di laboratorium untuk mengetahui kualitas air dan data sekunder berupa Data kapa...

Eighteen male white rats divided into three groups and were administered via peroral gavage with different treatments for five weeks. The treatment were Control (84 grams palm oil), P1 (84 grams palm oil with 2.3 grams plastic), and P2 (84 grams palm oil with 6.81 grams plastic). The histopathological changes of small intestine were examined by using Barthel Scoring method was analysed using Kruskal Wallis and continued with Mann-Whitney test. The result showed that were significant difference (p<0.05) between treatment groups. The worse damage of polypropylene plastic residue was 6.81 grams.

This research uses 30 mice which are divided into six treatment groups namely K0 (not infected without treated), K+ (infected without treated), K1 (infected and treated with chloroquin), K2 (infected and treated with juwet leaf extract), P1 (infected and treated with juwet leaf extract nanoparticle) and P2 (infected and combination treated with chloroquine and juwet leaf extract nanoparticle) which infected by 1x105 in 0.2 ml of Plasmodium berghei. The data were analyzed by Kruskal Wallis using SPSS and followed with Mann-Whitney test. This research result showed there was significant difference (p < 0.05) between K1 and P2, but did not showed significant difference (p > 0.05) with K+, K2 and P1. Based on this research, it could be concluded that nanoparticle juwet...

Twenty male mice of BALB/C strain with an average weight of 25 gram were used in this research. Total five experimental groups (4 mice each group) were treated with combination of TCDD and kebar grass extract designed as follows: (C-) 0mg/g BW/day dan 0µg/kg BW, (C+) 0mg/g BW/day and 7µg/kg BW, (T1) 0,045mg/g BW/day and 7µg/kg BW, (T2) 0,080mg/g BW/day and 7µg/kg BW, (T3) 0,1350mg/g BW/day and 7µg/kg BW. The TCDD was injected peritoneally in single dose while kebar grass extract was given orally everyday for 53 days. The results showed a significant difference (p<0,05) on group which is treated with kebar grass extract 0,135mg/ g BW/ day is proven could maintain the diameter of seminiferous tubules in T3 group (170,5μmb ± 0,65μm) compared with C+ group (129,50μma ± 8,42μm). Significant difference of epithelial thickness were also found between the con...

This pumice sand can be used as a substitute for normal sand as fine aggregate in a mixture of concrete mix. Based on the characteristic test examination, it can be seen that in testing the characteristics of pumice sand to the specifications of normal sand in specific gravity testing and weight testing of quicksand obtained results that are smaller than the specifications of normal sand and absorption tests obtained results greater than specifications on normal sand. The results of the normal sand compressive strength at BN is 250.95 kg /cm2 while the results of the floating sand concrete compressive strength on BPA is 224, 965 kg /cm2. Based on the research it can be concluded that with the same quality of concrete, the quality of K-250 is different in comparison to the compressive strength of concrete in normal sand and pumic...
