Judul: Studi literatur: peran madu dalam menjaga kesehatan dan terapi penyembuhan penyakit paru-paru
Abstrak: Madu termasuk ke dalam minuman fungsional yang dihasilkan oleh lebah penghasil madu dengan rasa manis dan memiliki berbagai fungsi untuk kesehatan. Madu berfungsi untuk menjaga kesehatan serta sebagai media terapi penyembuhan penyakit paru-paru karena memiliki kandungan gizi yang sangat baik. Kandungan gizi tersebut berperan sebagai anti-inflamasi, antibakteri dan antioksidan yang signifikan dengan kesehatan. Penelitian studi literatur ini dilakukan dengan melakukan penelusuran jurnal nasional maupun internasional yang dipublikasikan antara tahun 2011-2022 dengan menggunakan narrative review. Studi pustaka ini bertujuan mereview antar literatur mengenai kandungan gizi madu dan hubungannya untuk menjaga kesehatan, serta terapi penyembuhan penyakit paruparu. Hasil studi pustaka menunjukkan bahwa madu memiliki kandungan gizi lengkap. Kandungan gizi madu dapat dipengaruhi oleh jenis madu, faktor iklim, masa panen, dan jenis nektar yang di sekresi. Hidrogen peroksida sebagai antibakteri, sementara flavonoid, fenolik, fruktosa dan glukosa sebagai antioksidan dan anti-inflamasi yang merupakan kandungan gizi pada madu yang berpotensi memberikan efek untuk kesehatan dan penyembuhan penyakit paru-paru.

Judul: Uji Efektivitas Madu dari Empat Spesies Lebah Berbeda sebagai Agen Antibakteri.
Abstrak: Banyak penyakit yang diakibatkan oleh bakteri. Pengobatan infeksi dapat dilakukan dengan memberikan antibakteri pada luka. Salah satu antibakteri alami adalah madu. Tujuan dari penelitian ini adalah menganalisis efektivitas madu sebagai agen antibakteri. Bakteri target yang digunakan adalah Escherichia coli ATCC 8739, Staphylococcus aureus ATCC 6538 dan Pseudomonas aeruginosa ATCC 15442. Uji antibakteri terdiri dari 4 tahap yaitu uji disk, uji viabilitas, uji pH dan uji proksimat. Hasil uji antimikroba menunjukkan bahwa madu TG1_PND yang berasal dari Stingless Bee memiliki aktivitas antibakteri tertinggi dibanding madu lainnya. Hasil uji viabilitas menunjukkan ketiga bakteri mengalami penghambatan pertumbuhan terbaik dalam konsentrasi madu 100%. Adapun kandungan pH madu diuji melalui pengukuran menggunakan pH meter dan diketahui bahwa madu dengan kode TG1_PND memiliki pH terendah yaitu 2,7. Kandungan air pada madu dapat memengaruhi kualitas madu dan pertumbuhan mikroba., Many diseases are caused by bacteria. Treatment of infection can be done by giving antibacterial to the wound. One natural antibacterial is honey.The purpose of this study was to analyze the potential of honey as an antibacterial. The target bacteria used were Escherichia coli ATCC 8739, Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 15442. The test consisted of 4 stages, namely disk test, viability test, pH test and proximate test. The antibacterial test results showed that TG1_PND honey from Stingless Bee had the highest antibacterial activity compared to other honeys. The results of the viability test showed that the three bacteria experienced the best growth inhibition in 100% honey concentration. The pH content of honey was tested by measuring using a pH meter and it was found that honey with the code TG1_PND had the lowest pH of 2.7. Water content in honey can affect honey quality and microbial growth.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
