Bedak adalah salah satu sediaan kosmetik yang dipakai dalam jangka waktu yang lama. Bedak yang digunakan akan terjadi kontaminasi bahkan semakin meningkat seiring dengan lamanya pemakaian. Faktor-faktor yang mempengaruhi antara lain penyimpanan, lingkungan, dan spons bedak. Penggunaan spons bedak merupakan salah satu sumber cemaran bakteri. Di mana penggunaan spons yang sama secara berulang-ulang dan bersentuhan langsung pada kulit dapat meningkatkan jumlah mikroba. Tujuan penelitian ini adalah untuk mengetahui pengaruh lamanya penyimpanan, pemakaian suatu sediaan kosmetik bedak padat terhadap tingkat cemaran mikroba. Sampel yang diuji adalah bedak padat yang belum dipakai dan yang telah dipakai selama 2 minggu. Hasil penelitian berupa jumlah cemaran bakteri (ALT) dibandingkan dengan syarat menurut Peraturan Kepala Pengawasan Obat dan Makanan RI No.HK.03.1.23.07.11.6662 Tahun 2011 yaitu tidak boleh melebihi 103 koloni/g. Hasil uji cemaran bakteripada sediaan bedak padat sebelum pemakaian mempunyai nilai rata-rata ALT 2,6 x 101koloni/g dan sesudah pemakaian mempunyai nilai rata-rata ALT 9,2 x 101 koloni/g. Nilai ALT yang diperoleh dari masing-masing sediaan kosmetik bedak padat telah memenuhi syarat.Hasil uji t dependen menunjukkan adanya perbedaan jumlah bakteri pada bedak padat sebelum dipakai dengan setelah dipakai selama 2 minggu (t = 0.000). Kata Kunci: Kosmetik, bedak padat, Angka Lempeng Total ABSTRACTPowder is one of the cosmetic preparations used for a long time. Powder that is used will occur contamination even increasing along with the length of usage. This can be caused by several factors including storage, environment, powder sponges and others. The use of powder sponges is one source of bacterial contamination. Where the use of the same sponge repeatedly and in direct contact with the skin can increase the number of microbes. The objective of study was to determine the effect of the duration of use of a compact powder cosmetic preparation on the level of microbial contamination. The samples tested were solid powder that has not been used and that has been used for 2 weeks. The results of the study were the Total Plate Count (TPC) compared to the Regulation of the Head of the Republic of Indonesia Drug and Food Control Number HK.03.1.23.07.11.6662 of 2011 concerning the Requirements for Microbial Pollution and Heavy Metals in Cosmetics which should not exceed 103 colonies / g. The test results of bacterial contamination on solid powder preparations before use have an average value of ALT 2,6 x 101 colony / g and after use have an average ALT value of 9.2 x 101 colony / g. The ALT value obtained from each compact powder cosmetic preparation has met the requirements. The results of the dependent t test showed a difference in the number of bacteria on solid powder before use with after being used for 2 weeks (t = 0.000). Keywords: Cosmetics, Compact Powder, Total Plate Count

The amount of rubber seed waste in Indonesia is highly yielded as a side product from a large amount of rubber trees plantation. The rubber seed was not processed become the usefull application yet, thus it becomes a high volume of waste in each year. An initiative should be done to turn it as a practical material. The rubber seed is potential for natural composite along with the increasing attention toward natural composite application.This work aims to produce natural fibre composite based on rubber seed and characterize it's mechanical properties. In this work, the rubber seed natural composite produced by using the hand lay-up method. Polyester resin YUCALAC BQTN-157 was used as the matrix with the addition of 1% MEKP (Methyl-Ethyl-Ketone- Peroxide) as the catalyst. Mechanical properties of the composite were examined by using a tensile and bending test. Additionally, the water absorption test was performed according to the ASTM D 570. The result showed that the tensile and bending strength decrease with increasing the filler composition, which is added in the composite. The composite, which has the filler composition of 40% was generate the highest tensile strength. In contrast, the lowest tensile strength appeared at the composite with a filler of 60%. The bending strength trend also behaves similarly with the tensile strength as the filler composition increased. Water absorption ability of composites displays the acceptable value as it shows within the range of 2.22-2.96%.

Background: The use of traditional medicines is increasingly massive, it takes packaging and handling practical ways for the community. Soursop leaf is one of the herbs known to have many pharmacological properties for health. Capsules are an alternative form of packaging that is efficient for the community because in addition to ease of use, it can also mask the unpleasant taste and smell of simplicia.Objectives:  This aims to improve the skills of students in the use of soursop (Annona Muricata L.) leaves for the prevention and treatment of various diseases.Methods: This study was used a quasi-experimental design with a postest only approach. This activity was carried out by providing counseling (lecture method) and providing skills on how to package the soursop leaf simplicia powder into a capsule shell on 28 November 2018 at Suka Makmur High School, Aceh Besar. Direct data collection, and analysis using t-dependent tests.Results: The results of the study have shown an increase in the skills of students in the use of soursop (Annona muricata L.) leaves for the prevention and treatment of various diseases after counseling (p <0.05).Conclusion: Increasing the knowledge of students related to prevention and treatment can be done through counseling, namely counseling about the use of soursop leaves (Annona muricata L.)

This study aimed to examine and analyze the effect of Income Variance, Expenditure Variance, Financial Autonomy, and Surplus Accumulation on the prediction model of Regional Budget Changes in districts and cities in the province of South Kalimantan. The data used in this study is secondary data derived from reports on budget realization and regional expenditure budgets. The population in this study were all districts and cities in the province of South Kalimantan for the 2015-2019 period. The number of districts and cities in this study were 12 local governments with an observation period of five years. The data analysis technique used is multiple linear regression analysis using the SPSS Version 25 program. The test results show that the Income Variance, Expenditure Variance, and Accumulated Surplus significantly affect Changes in the Regional Budget. In contrast, the Financial Independence variable has no significant effect on Changes in the Regional Budget.
