Judul: Modification design of incinerator multifunction continue type
Abstrak: Incinerator is an equipment to incinerate trashes with high temperature control to ensure that the combustion process was done completely. The previous design of batch type incinerator which has been designed by Pradipta (2011) has some disadvantages, such as heat transfer system, loading and unloading system, air supply system and utilization of heat energy. So, those design should be modified to improve its performance. The performance parameters of incinerator are temperature of combustion, the rate of combustion, quality of exhaust gases, safety factor, and utilization of heat energy. Modified incinerator has eight sections (combustion chamber, chimney, air inlet, hopper, boundary plate, ash chamber, charcoal chamber, and water heater pipe). The performance test shows that the highest combustion temperature is 689.6 ⁰C, with combustion rate 5.78 kg / hour. The incinerator is safe for operator and the exhaust gasses has good quality. Utilization of thermal energy could increasing water temperature up to 32 ⁰C. Air inlet position was not in the proper place, so combustion temperature could not reach as high as expected. Therefore it need improvement.

Judul: Design Modification of Continuous Type Incinerator as Burner Tool for Medical Waste
Abstrak: Aktivitas pelayanan kesehatan masyarakat seperti rumah sakit dan puskesmas berpotensi sebagai penghasil limbah Bahan Berbahaya dan Beracun (B3) yang berpotensi menyebabkan terjadinya pencemaran lingkungan. Limbah medis mengandung biohazard, sehingga harus dimusnahkan, antara lain dengan menggunakan alat atau instalasi pembakar sampah (incinerator). Incinerator merupakan alat penanganan sampah dengan menggunakan proses pembakaran yang dikendalikan melalui pembakaran dengan suhu tinggi. Incinerator rancangan Pane (2013) yang telah dimodifikasi oleh Miftah (2016) belum memenuhi kriteria sebagai incinerator pembakar limbah medis yang mensyaratkan suhu pembakaran minimum 800 ⁰C. Penelitian ini bertujuan untuk melakukan modifikasi incinerator rancangan Pane (2013) agar mampu mencapai suhu pembakaran minimum 800 ⁰C. Modifikasi difokuskan pada upaya peningkatan kinerja sistem pembakaran dengan memperbaiki sistem pemasukan udara pada incinerator. Parameter yang diukur dalam uji kinerja incinerator hasil modifikasi tersebut adalah suhu pembakaran, laju pembakaran, kualitas asap buang, faktor keamanan, dan pemanfaatan energi panas. Uji kinerja menggunakan bahan campuran limbah kain perca dan botol plastik, karena penggunaan limbah B3 di kampus tidak memungkinkan. Hasil uji kinerja menunjukkan bahwa suhu pembakaran mampu mencapai 980 ⁰C dengan laju pembakaran sebesar 9 kg/jam. Pemanfaatan energi panas yang dihasilkan mampu memanaskan air hingga 86 ⁰C dengan debit aliran air sebesar 0,018 lt/detik, dan mengarangkan tempurung kelapa di ruang pengendapan asap sebanyak 2-2,5 kg arang dengan kualitas baik. Dengan demikian, modifikasi yang dilakukan telah sukses menghasilkan incinerator yang memenuhi kriteria sebagai pembakar limbah medis., Public health services such as hospitals or other health center tend to be the waste producer, which some of them are labeled as hazardous and toxic waste (B3) which eventually cause environmental pollution. One of the possible solution is to burn the waste by using incinerator. Basically, incinerator is a waste burner which was using high temperature to burn medical waste. Incinerator designed by Pane (2013) and modified by Miftah (2016) has not yet meet the ideal criteria for a medical waste incinerator, that requires combustion temperature level more than 800⁰C. This reasearch aims to improve combustion in order to reach the temperature level higher than 800 ⁰C by air intake system modification. Combustion process temperatures, smoke quality, safety factor, and energy utilities are the parameter which determined as incinerator performance. The performance test used a mixture of patchwork waste and plastic bottles, because of using B3 waste on campus is not possible. The result of this research showing that combustion temperature successfully increased up to 980 ⁰C for combustion rate of 9 kg/hour. Utilization of heat energy produced by combustion process inside the chamber, successfully produce 2-2,5 kg of good quality coconut shell charcoal and hot water of 86 ⁰C at 0,018 lt/hour flow rate. The modifications carried out has been successful on producing medical waste incinerator.

Judul: Analisis Stabilitas Nilai tukar di Negara ASEAN-5 Sebelum dan Saat Pandemi Covid-19
Abstrak: Covid-19 merupakan salah satu wabah penyakit yang memiliki pengaruh terhadap ekonomi ASEAN-5 terutama pada nilai tukar. Nilai tukar adalah salah satu alat yang digunakan untuk melakukan transaksi keuangan antar negara. Apabila nilai tukar bergejolak akan memengaruhi ekonomi suatu negara terutama dalam perdagangan internasional. Faktor-faktor yang memengaruhi nilai tukar dapat dari segi ekonomi maupun non ekonomi. Dari segi ekonomi nilai tukar dipengaruhi oleh inflasi, ekspor dan impor, serta lainnya. Sedangkan faktor non ekonomi dilihat dari politik, pandemi, dan lainnya. Dalam penelitian ini, Covid-19 disertakan sebagai variabel yang diduga dapat memengaruhi nilai tukar. Penelitian ini menganalisis stabilitas nilai tukar ASEAN-5 sebelum dan saat pandemi Covid-19. Selain itu, pengaruh faktor makroekonomi seperti inflasi luar negeri, perbedaan suku bunga, ekspor, pertumbuhan ekonomi pada negara ASEAN-5 sudah diamati. Analisis yang digunakan adalah panel statis. Berdasarkan hasil penelitian, nilai tukar cenderung berfluktuasi pada saat Covid-19. Selain itu, Covid-19 berpengaruh negatif dan signifikan terhadap pertumbuhan ekonomi tetapi tidak berpengaruh signifikan terhadap ekspor. Selanjutnya, pertumbuhan ekonomi dan ekspor serta perbedaan suku bunga dan inflasi luar negeri berpengaruh signifikan terhadap perubahan nilai tukar negara ASEAN-5 Kata kunci: ASEAN-5, Covid-19, Nilai Tukar, Panel Statis, Covid-19 is one of diseases that have impact on ASEAN-5 Economics especially on Exchange rates. Actually, Exchange rate is one of tools that used for international financial transactions. If exchange rate had high volatility, it would influence economics including international trades. Factors that influenced exchange rates can be seen from economics and non-economics. From economics, variables that have impact on exchange rates such as inflation, export and import, and etc. While from non-economics were politics, pandemic and etc. Covid-19 could be being factor that influenced exchange rates. Therefore, this research has the objectives to analyse stability of ASEAN-5 exchange rates before and during Covid-19. In other sides, it wants seeing influence of macroeconomics factors like foreign inflation, interest differential, export, economic growth in ASEAN–5 Countries. This research used static panel. The result showed exchange rates were more stabil before it came to ASEAN-5 and Covid-19 had negative and significant correlation with economic growth but not to export. In other side, all of macroeconomic factors had significant correlation with exchange rates Keywords: ASEAN-5, Covid-19, Exchange Rates, Static Panel
