The Application of Bibliotheraphy on Adolesenc Girls with Body Image Dissatisfaction

Body image dissatisfaction, caused by a discrepancy between cultural-based ideal body and individual actual body, is experienced by most of adolesencet girls. The purpose of this study is to evaluate the effectiveness of bibliotherapy on adolescence girls with body image dissatisfaction. Subjects were 15 senior high school girls, aged 14-17 years, with BMI (Body Mass Index) thin to normal, with average to high body image dissatisfaction. By using pretest-posttest control group design, the subjects were assigned into three groups i.e. interactive and reading bibliotherapy as experimental groups and the waiting-list control group. One-way analysis of variance (ANOVA) is employed to measure the differences of body dissatisfaction among the three groups. The result showed that there were no significant differences of body dissatisfaction in the pretest – posttest and posttest – follow-up, between the three groups. It means that neither interactive nor reading bibliotherapy was effective in reducing the adolescence girls’ body image dissatisfactio

Effect of the addition of inhibitors of kirinyuh leaf (Chromolaena Odorata) in methanol extract on corrosion rate of ASTM 36 steel

Kirinyuh leaves (Chromolaena Odorata) contain alkaloids, saponins, flavonoids, phenols, and tannins with the potential as a natural inhibitor that can be used to inhibit the rate of corrosion. Kirinyuh leaf extract inhibitors were added at various concentrations of 100 ppm, 200 ppm, 300 ppm, 400 ppm, and 500 ppm, which were sprayed onto the sample surface before being soaked for seven days. Calculation of the corrosion rate using the method of weight loss (weight loss). The results showed that kirinyuh leaf extract effectively inhibited the corrosion rate. The smallest corrosion rate value was found in the sample with the addition of 400 ppm inhibitor concentration, which was 2.053 ppm. Meanwhile, an efficiency inhibitor was also found in the same concentration of inhibitor that is equal to 87%

IMPLEMENTING E-PLANNING SYSTEM IN LOCAL GOVERNMENT DECISION-MAKING: A CASE STUDY IN INDONESIA

This study aims to evaluate the application of the e-planning system in local government decision-making in Indonesia. The research method used is descriptive with a qualitative approach. The study results show that the e-planning system in Indonesia has been implemented by several sectors, such as government, health, and education, through SIPPD, SIKDA, and PDSPK. Applying the e-planning system in local government decision-making has advantages such as efficiency, effectiveness, and planning, providing transparent information, increasing accountability, facilitating reporting and evaluation, human resources, budget constraints, and unsupportive policies. This research produces recommendations for increasing the implementation of the e-planning system in local government decision-making in Indonesia, such as increasing community participation, training, and education for system users, as well as stronger policy support. In conclusion, implementing an e-planning system can benefit local government decision-making, but it also requires efforts to overcome existing obstacles. This research is expected to contribute to the development of e-planning in Indonesia

Waste cellulose extraction and analysis decortication sisal plant (Agave sisalana) Sumbawa Labangka

Waste utilization of decortication Sisal plants is minimal compared to the amount of waste produced, especially the cellulose content in the waste decortication sisal plant. This research aims to extract waste cellulose decortication sisal plants using acid and alkaline solutions with variations in NaOH solutions of 0%, 2%, 4%, 6%, and 8%. The process used is alkalization, bleaching, and acid hydrolysis by method analysis. Next, testing using SEM and FTIR methods is done to determine the morphology of waste cellulose decortication in the resulting sisal plants and the cellulose, lignin, and hemicellulose content in the waste decortication sisal plant. Before treatment, the cellulose content of the waste is given to decorticate the sisal plant at 31%, and after alkalization treatment, the cellulose content is 54%. Cellulose content in waste decortication Sisal plants in each process increases with found O-H bonds at waves 3000-3600 cm-1, C-H bonds belong to hemicellulose at wave numbers 2800-3000 cm-1 and remove lignin, which is in the waste decortication Sisal plants did not find C=C bonds belonging to lignin at waves of 1200-1300 cm-1. FTIR test results show an increase in cellulose intensity, with the resulting cellulose measuring 28.64762 µm and 33.69369 µm. The increase in cellulose intensity in FTIR is directly proportional to the SEM results, which show a loose layer with lignin and hemicellulose that has been eroded from the cellulose

Pengaruh Ukuran Partikel, Persen Padatan, dan pH pada Proses Flotasi Terhadap Perolehan Kembali Tembaga

Flotasi merupakan proses ekstraksi logam berdasarkan perbedaan tegangan permukaan dari mineral di dalam air dengan cara mengapungkan mineral ke permukaan. Faktor yang mempengaruhi nilai perolehan kembali Tembaga antara lain ditentukan oleh ukuran partikel, jumlah persen padatan dan kondisi larutan. Pada penelitian ini akan dilakukan pengamatan terhadap perolehan kembali mineral tembaga dengan melakukan variasi ukuran partikel, variasi persen padatan pada jumlah 33%, 42% dan 47% dan variasi pH larutan pada kondisi basa yaitu pH 10, 10.3 dan 10.6. Pengecilan ukuran partikel dilakukan dengan proses Grinding sampai mendapatkan ukuran + 212 mikron. Selanjutnya, pH larutan dikontrol dengan penambahan kapur. Analisis perolehan kembali mineral tembaga secara kuantittatif dilakukan dengan karakterisasi AAS. Hasil penelitian menunjukkan bahwa ukuran partikel yang optimum didapat pada pada variasi 3% +212 mikron dengan nilai 95.12%. Sedangkan, jumlah persen padatan 42% memberikan nilai tertinggi yaitu 95.12%. Selanjutnya, diperoleh pH terbaik untuk memperoleh tembaga yang optimum yaitu pada pH 10.6 sebesar 95.12

Preparation of synthesis nanoparticles Fe3O4 based on iron sand Sumbawa

Iron sand generally contains minerals such as ilmenite, magnetite, and hematite. Based on the results of previous tests, the main composition of iron sand in Rhee, Sumbawa regency, is magnetite. One method to increase the Fe content in iron sand is by pre-treatment with NaOH. NaOH is also used to precipitate heavy metals in a mineral. In this study, three variations were carried out with the ratio of NaOH: iron sand, namely: 1: 4, 2: 4, and 3: 4 at a temperature of 300 C. Furthermore, the calcination results were followed by the synthesis of Fe3O4 nanoparticles using the coprecipitation method. The results of the XRF characterization showed an increase in Fe levels after being processed by the alkalization treatment. The highest concentration was obtained in 1:4, with a Fe percentage of 91.1%. The results of the XRD characterization showed that the synthesis of Fe3O4 was successfully carried out with single phase Fe3O4 amlording to the data reference 96-9005839 forms and the space group F d -3 m. Crystal size analysis Using the Debey-Scherrer equation, the respective sizes were 12.7 nm, 8.71 nm, and 9.76 nm, respectively
