Judul: Analisis Persepsi Konsumen terhadap Produk Bakso Kemasan di Kabupaten Garut
Abstrak: Konsumen dapat mempersepsikan produk bakso kemasan sesuai dengan manfaat dan risiko yang akan didapat selama pemilihan sampai pembelian. Penelitian ini bertujuan mengidentifikasi karakteristik konsumen, menganalisis persepsi konsumen di Kabupaten Garut terhadap produk bakso kemasan, juga mempelajari perilaku konsumen dalam memilih produk bakso kemasan. Pengumpulan data dilakukan melalui pengisian kuesioner survei kepada 100 responden di Kabupaten Garut serta dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa konsumen bakso kemasan di Kabupaten Garut didominasi oleh konsumen perempuan, berusia 20-25 tahun atau berstatus sebagai mahasiswa, dengan tingkat pendidikan yang cukup baik. Persepsi konsumen terhadap produk bakso kemasan memiliki kategori yang sangat baik. Konsumen memahami konsep produk pangan seperti bakso kemasan. Perilaku pembelian pada bakso kemasan dilakukan secara mendadak dengan intensitas sebulan sekali. Konsumen mementingkan harga dari jenis bakso ayam dan daging serta bakso sapi sebagai makanan camilan yang didapat dari sumber media sosial, keluarga, serta teman. Penelitian dapat menjadi gambaran dan solusi untuk mengembangkan bakso kemasan di Kabupaten Garut.

Judul: Analisis Pola Konsumsi Pangan Sumber Protein Hewani di Kabupaten Garut
Abstrak: Salah satu bahan pangan yang berperan penting dalam menciptakan kualitas sumber daya manusia adalah protein hewani seperti ikan, daging, telur, dan susu. Pemerintah melalui Kementerian Perdagangan menetapkan harga acuan untuk komoditas pangan agar terjangkau oleh seluruh masyarakat. Penelitian ini bertujuan menganalisis pola konsumsi pangan sumber protein hewani rumah tangga di Kabupaten Garut dan pengaruh perubahan harga daging sapi dan ikan terhadap pola konsumsi dan kecukupan protein hewani rumah tangga. Data yang digunakan berasal dari Survei Sosial Ekonomi Nasional (SUSENAS) 2016 dengan metode analisis Almost Ideal Demand System (AIDS). Hasil penelitian menunjukkan bahwa elastisitas permintaan pangan sumber protein hewani secara dominan bersifat inelastis. Nilai elastisitas harga silang pangan sumber protein hewani secara dominan bernilai negatif (barang komplementer). Elastisitas pengeluaran bernilai positif untuk semua komoditas pangan sumber protein hewani. Dampak terbesar dari penurunan harga daging sapi terjadi pada golongan pendapatan tinggi karena pola konsumsi pangan hewaninya mengalami peningkatan yang signifikan. Penurunan harga ikan berdampak positif bagi golongan pendapatan rendah karena kecukupan protein hewaninya terpenuhi.

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.
