Judul: Estimation of the Economic Value Of Tourism and COVID-19 Impact to Loji Pine Forest, Blitar District
Abstrak: Pada Desember 2019, Virus COVID-19 pertama kali muncul di Wuhan, Cina dan menyebar ke seluruh dunia termasuk Indonesia. Penyebaran virus COVID-19 yang telah meluas ke berbagai belahan dunia berdampak pada penutupan tempat wisata. Pemberlakuan kebijakan new normal dan Pemberlakukan Pembatasan Kegiatan Masyarakat (PPKM) berdampak pada tingkat kunjungan wisatawan salah satunya pada wisata Hutan Pinus Loji. Tujuan dari penelitian ini adalah: (1) mengetahui persepsi wisatawan terhadap kondisi Hutan Pinus Loji, (2) mengidentifikasi dampak pandemi COVID-19 terhadap tingkat kunjungan wisata Hutan Pinus Loji, (3) mengetahui persepsi wisatawan terhadap COVID-19, (4) mengidentifikasi faktor-faktor yang mempengaruhi tingkat kunjungan wisata Hutan Pinus Loji, (5) mengestimasi nilai ekonomi wisata dari Hutan Pinus Loji. Penelitian ini menggunakan metode skala likert, travel cost method, dan analisis regresi poisson. Hasil penelitian menunjukan persepsi wisatawan terhadap kondisi Hutan Pinus Loji adalah sangat baik. Hasil perbandingan jumlah wisatawan Hutan Pinus Loji tahun 2018 – April 2021 menunjukkan bahwa virus COVID-19 tidak mengurangi jumlah kunjungan wisatawan. Kesadaran wisatawan atas masalah wabah virus COVID-19 dan pentingnya penerapan protokol kesehatan sudah sangat baik. Hasil estimasi nilai ekonomi wisata Hutan Pinus Loji sebesar Rp 38.186.813 per tahun dan terdapat dua faktor yang berpengaruh terhadap jumlah kunjungan yaitu lama mengetahui dan persepsi rata-rata wisatawan terhadap kondisi Hutan Pinus Loji., In December 2019, COVID-19 virus first appeared in Wuhan, China, then spread throughout the world including Indonesia. The outbreak has forced the closure of many tourist attractions. The implementation of the new normal policy and mobility restriction (PPKM) influence the level of tourist visits in many tourist sites including Loji Pine Forest. This research aims to: (1) analyze tourist perceptions regarding to Loji Pine Forest condition, (2) identify the impact of the COVID-19 on the level of tourism visits at Loji Pine Forest, (3) analyze tourist perceptions related to COVID-19 pandemic, (4) identify factors that influence the number of visits to Loji Pine Forest, (5) estimate the economic value of tourism of Loji Pine Forest. The data analysis method used in this research is the likert scale analysis, descriptive analysis, travel cost method, and Poisson regression. The results show that tourists' perception on Loji Pine Forest condition is very good. The data on tourist visits during 2018 – April 2021 shows that the COVID-19 outbreak did not reduce the number of tourist visits to Loji Pine Forest. Tourists’ awareness on the pandemic and the importance of health protocol is very good. The estimation results of the economic value of tourism is IDR 38.186.813 per year. There are two factors that affects the number of visits: duration of recognition and tourists’ average perception on the condition of Loji Pine Forest

Judul: Estimating the Existence Value of an Open Green Space and the  Impact of COVID-19 Pandemic on Visitor Preferences (Case Study: Situlembang  Park, Central Jakarta)
Abstrak: Taman Situlembang adalah ruang terbuka hijau (RTH) berupa taman pubik yang dimiliki kota Jakarta Pusat. Keberadaan Taman Situlembang dan peningkatan kualitas taman menjadi hal yang penting karena provinsi DKI Jakarta diharuskan memiliki RTH minimal 30%. Taman Situlembang memiliki banyak peran penting dari menjaga keseimbangan lingkungan hingga menyediakan fasilitas umum untuk olahraga dan edukasi bagi masyarakat. Pada masa pandemi COVID-19, RTH dapat menjadi solusi bagi masyarakat perkotaan yang membutuhkan ruang dan aktivitas pariwisata yang aman.Tujuan penelitian ini adalah: (1) menganalisis persepsi pengunjung mengenai kondisi lingkungan di Taman Situlembang, (2) menganalisis persepsi pengunjung terhadap pandemi COVID-19, (3) menganalisis dampak pandemi COVID-19 terhadap tingkat kunjungan dan preferensi kegiatan pengunjung di Taman Situlembang, (4) mengidentifikasi faktor-faktor apa saja yang memengaruhi tingkat kunjungan di Taman Situlembang, (5) mengestimasi nilai ekonomi keberadaan Taman Situlembang. Hasil analisis menunjukkan bahwa persepsi pengunjung mengenai kondisi lingkungan di Taman Situlembang termasuk dalam kategori baik dengan skor rata-rata 3.07. Persepsi pengunjung terhadap pandemi COVID-19 berada dalam kategori sangat baik dengan skor rata-rata 3.34. Tingkat kunjungan Taman Situlembang pada saat pandemi mengalami peningkatan sebesar 101,50%. Faktor yang memengaruhi tingkat kunjungan adalah biaya perjalanan. Nilai WTP rata-rata sebesar Rp 66.046,48 per membership per orang per tahun dan nilai total WTP responden adalah sebesar Rp 355.330.062 per tahun., Situlembang Park is an open green space (OGS) and public park owned by the City of Central Jakarta. The existence of Situlembang Park and the improvement of its quality are important as the Jakarta Province is required to have minimum 30% green open space. Situlembang Park plays many important roles, from maintaining the environmental balance to providing public facilities for sport and education. Ultimately in this COVID-19 Pandemic situation, OGS may become a solution for the urban communities who need safer tourism space and activities. The aims of this study are: (1) to analyze the visitor perception of the environmental conditions of Situlembang Park, (2) to analyze the visitor perception of COVID-19 Pandemic, (3) to analyze the impact of COVID-19 Pandemic to Situlembang Park visit rate and visitor preferences, (4) to identify factors that affect Situlembang Park visit rate, (5) to estimate the existence value of Situlembang Park. The result shows that the visitor perception of the Situlembang Park’s environmental condition is categorized as “good” with an average score of 3.07, while the visitor perception of COVID-19 Pandemic is categorized as “very good” with an average crore of 3.34. Number of visits increases to 101,50%. Travel cost is the significant factor that affect visit rate. The respondent’s annual average Willingness to Pay (WTP) is RP 66.046,48 per membership per person. The estimated existence value of Situlembang Park is given by estimated total annual WTP, which is RP 355.330.062.

Judul: Membran Komposit Kitosan-Natrium Alginat untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Composite of chitosan and sodium alginate can be utilized as base material of proton exchange membrane (PEM). The composite membranes were produced by various concentrations of chitosan-sodium alginate, namely 3:3, 3:4, 3:5, 3:6, 4:3, 5:3, and 6:3 (% b/v). The composites were characterized by using Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), and were tested for the performance as PEM from the proton conductivity obtained by using impedance spectrometer. The FTIR spectrum indicated the NH3C group at 1637.29 cm-1 and symmetrical COO group at 1253.68 cm-1 indicating interactions between chitosan and sodium alginate. SEM micrographs showed that the composite membrane was nonporous. Composite membrane with 3:5 chitosan-sodium alginate composition had the highest proton conductivity, namely 9.594 × 10-7 S/cm. Based on this research results, chitosan-sodium alginate composite membrane can be applied well in direct methanol fuel cell system.
