Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kadar perekat terhadap sifat papan partikel bambu. Bambu yang digunakan adalah bambu betung (Dendrocalamus asper), sedangkan perekatnya adalah urea formaldehida (UF) cair. Bentuk partikel bambu yang digunakan adalah untai. Papan partikel bambu sekala laboratorium dibuat dengan target kerapatan 0,70 g/cm3 dengan kadar perekat bervariasi yaitu 8, 9, 10, 11 dan 12% dari berat kering partikel bambu.Hasil penelitian menunjukkan bahwa sifat fisis dan mekanis papan partikel bambu sangat dipengaruhi oleh kadar perekat yang digunakan. Semakin tinggi kadar perekat semakin baik sifat papan partikel bambu yang dihasilkan. Penggunaan kadar perekat minimum 11% dari berat kering partikel bambu menghasilkan papan partikel bambu yang cukup kuat dan stabil serta memenuhi persyaratan Standar Nasional Indonesia.

Abstract

Rain Water Harvesting is a method of water conservation by flowing rainwater into a single point of basin on the surface of the earth.  This method can be applied to areas that have a supporting topography including the educational environment.  The Lampung University area has several points of basin to hold rainwater, one of them is a water basins in the area of Simple Flats for University of Lampung can be used to do water conservation through the construction of small dam.The methods are used to redesign this small dam conservation are hydrological , small dam conservation construction planning , analysis stability of  planned constructions and the last method is estimating building construction cost.  Small dam conservation planned height of 4 m, with a base elevation at +107,00 m the dam crest elevation +110,00 m, dam crest width 2 m, the slope of 1:1,5.  The inflow debit of 0,987 m³/sec and the outflow debit of 0,586 m³/sec with cycle period 5 years. Spillway which used is free overflow type and basin specific energy building Vlugter type.  Stability small dam conservation at simple rental flats University of Lampung construction stated as safe. Reservoir volume after planned to be 29.160,750 m3, increasing from the previous volume 3.309,741 m3.  Cost estimated of design planning of conservation small dam is Rp. 7.323.901.000,00. Keywords: Small dam, Conservation, University of Lampung.

Abstract: This study aims to determine the differences in the integrity character values of students before and after outbound therapy is given, and to know the effect of outbound therapy to improve the integrity character values in students. Research conducted at SMP Negeri 5 Pekanbaru on 20 subjects with a purposive sampling technique. The study design was pre-experimental with one group pre-test post-test. The data collection instruments used are instruments consisting of indicators of integrity character values. The results showed that there were differences in the level of integrity of students before and after being given Outbound therapy with a significance value of 0,00 < α 0.05. The integrity character values of students who were the subject of research 20 students who were previously in the low category after being given outbound therapy were mostly in the moderate category. In addition, based on the Spearman rank test, it is known that there is a significant influence of Outbound therapy on the integrity character value of students, which is 22.5% while 77.5% is influenced by other factors originating from outside and within the student. Key Words: Outbound Therapy, Integrity Character Value

Abstract

Flocculation is one of processes to obtain clean water. Starch-graft-polyacrylamide (St-g-PAM) is a copolymer flocculant. This flocculant is synthesized by the “grafting to” method. This study aims to determine the effects of initiator concentration ratio, the terminator concentration and the termination time towards the obtained flocculant performance. Polymerization was carried out in a glass reactor equipped with a stirrer and isothermal conditions. The resulting products were analyzed by FT-IR. The analysis shows the existence bonds of starch and acrylamide. The presence of these groups proves that St-g-PAM was formed. The effect of initiator concentration ratio showed that the performance bioflocculant from mocaf more effective than bioflocculant from modified taro strach, with the higher change value is 76,19 %. Meanwhile, the effect of the terminatorconcentration and the termination timeshowed that the performance bioflocculant from modified taro strach more effective than mocaf, the higher change valuesare 68,57% and 71,76%, respectively.

Abstract

Background: Prostate tuberculosis (PTB) is one of extra pulmonary tuberculosis which potentially has more frequent fatal complications and more severe quality of life deterioration. It is a very rare disease, with prevalence of 2.6% of all urogenital tuberculosis (UGTB). Prostate tuberculosis may be a sexually transmitted disease and leads to sexual dysfunction. Case: Male, 54 years old, with urinary retention, dysuria, flank pain in the last 1-month, recurrent urinary tract infection in the past 1 year and decrease body weight of 8 kg in 1 month. Physical examination demonstrates enlarged prostate. Patient was referred to Wangaya Hospital with benign prostate hyperplasia (BPH) and suspect malignancy. After underwent clinical and supporting examination, patient underwent TURP procedure. Histopathology examination revealed PTB. Patient was then treated with first line anti-tuberculosis drug (ATD). Discussion: Multiple risk factors are involved in TB disease. PTB spread occur through hematogenous, lymphatic, or direct routes. Clinical features and supporting examinations of PTB are non-specific. Diagnosis often made through incidental histology finding post TURP. Standard ATD regiment administered based on World Health Organization (WHO) guideline. Duration can be prolonged due to suboptimal concentration to prostate tissue. Conclusion: Multidisciplinary approach for extra pulmonary TB is needed. Thorough history taking, and high index of suspicion are important aspects. PTB diagnosis should be considered in patients with recurrent lower urinary tract symptoms refractory to standard therapy in TB endemic area.
