Pola Pergerakan Orang di Masa Pandemi dengan Pendekatan Eksploratif di Wilayah Kepulauan Bangka Belitung

COVID-19 has spread around the world and has given a huge impact on people's lives. One of the changes in the COVID-19 condition is the travel pattern of people. Travel patterns can be explained in terms of the flow of vehicles, passengers, and people's mobility from the origin and destination zones within a certain area and period. On the other hand, it is known that travel patterns are an essential factor in solving transportation problems. The change of travel pattern data is needed for transportation planners and policymakers in providing safe transportation during the pandemic. In addition, data on travel patterns also play an important role in determining travel restrictions in an area to reduce the spread of COVID-19. This study tries to analyze travel patterns during the COVID-19 pandemic through an exploratory approach by taking a case study in the Bangka Belitung Province. The results of this study show that the mobility was dominated by intra-island trips during the pandemic, both within Bangka Island and Belitung Island. Furthermore, during the COVID-19 pandemic, the majority of people made changes to their routine's mobility. More than 50% of people did not return to their original travel patterns even though the pandemic conditions had entered the New Normal period. The most influential factor which makes people change their mobility is to take precautions from COVID-19.COVID-19 has spread around the world and has given a huge impact on people's lives.

PRARANCANGAN PEMBUATAN GARAM INDUSTRI/SODIUM CHLORIDE DARI AIR LAUT DENGAN PROSES VACUUM PAN KAPASITAS 200.000 TON/TAHUN

Garam merupakan senyawa ionik yang terdiri dari ion positif /kation serta ion negatif/anion, sehingga membentuk senyawa netral (tanpa bermuatan). Garam yang terbentuk dari hasil reaksi kimia asam maupun basa. Komponen ini berupa senyawa anorganik seperti klorida (Cl−),   bisa juga berupa senyawa organik seperti asetat (CH3COO−) dan ion monoatomik seperti fluorida (F−),  serta ion poliatomik seperti sulfat (SO42−). Kelarutan garam didalam air sebesar 35,9 g/100ml (25oC). Pabrik ini  direncanakan beroperasi selama 330 hari/tahun dengan kapasitas produk garam industri sebesar 200.000 ton/tahun dan rencana didirikan pada tahun 2025. Pembuatan garam industri dilakukan dalam reaktor alir berpengaduk (RAB) dengan reaksi bersifat seri eksotermis. Reaksi dilangsungkan pada suhu sekitar 50℃ dan tekanan  sekitar 1 atm. Hasil dari keluaran reaktor dibawa ke flokulator untuk mereaksikan  pengotor - pengotor yang ada dalam feed dengan penambahan Na2CO3 dan Ca(OH)2.    Larutan brine dipompakan menuju settling tank lalu ke tangki penampung dengan suhu 30℃ dan tekanan 1 atm. Larutan brine akan dipompakan dengan pompa menuju evaporator yang beroperasi pada suhu 125,98℃ dan tekanan 1 atm  untuk  memekatkan larutan brine dengan cara menguapkan kandungan air.  Larutan brine dari evaporator dialirkan ke dalam vacuum pan crystallizer yang berfungsi untuk membentuk kristal garam. Vacuum pan    crystallizer beroperasi pada suhu 94,8℃ dan tekanan 1 atm.    Kristal yang terbentuk dari proses kristalisasi akan dipisahkan menggunakan centrifuge setelah itu kristal garam akan diumpankan ke dalam alat pengering rotary dryer yang beroperasi pada suhu 82℃ dan    tekanana atm.  Kristal garam yang terikut bersama udara pengering ditangkap oleh  cyclone. Pada cyclone dipisahkan antara kristal garam dengan udara pengering.  Kristal garam kering yang keluar dari rotary dryer bersamaan dengan hasil dari cyclone diangkut dengan    screew conveyor  menuju crusher untuk menghaluskan kristal garam kemudian disaring menggunakan  screener untuk menyeragamkan  ukuran produk. Selanjutnya diangkut  menggunakan bucket elevator menuju bin.  Diperoleh produk NaCl dengan kemurnian 99,7%. Pemasaran sodium chlorida sangat diutamakan untuk konsumsi dalam negeri. Bentuk perusahaan yang dipilih berupa Perseroan Terbatas (PT)  menggunakan sistem   organisasi line  dan staff.    Sistem kerja karyawan di pabrik ini dipilih berdasarkan pembagian menurut    jam kerja shift dan non-shift dengan tenaga kerja yang dibutuhkan sebanyak 170 orang. Adapun hasil analisa ekonomi memberikan hasil investasi modal total (TCI) adalah berkisar Rp 740.309.323.835,-  dan didapat hasila penjualan yaitu berkisar Rp 1.300.000.000.000,-. Selain itu diperoleh juga Return of  Investment  (ROI)  sebelum pajak berkisar 39% dan Return of  Investment (ROI) sesudah pajak berkisar 25%. Pay Out Time (POT) sebelum pajak yaitu 2,04 tahun dan Pay Out Time (POT) sesudah pajak sebesar 2,82 tahun. Maka dari itu diperoleh Break Event Point (BEP) sebesar 41% dan Shut Down Point (SDP) sebesar 25%.  Berdasarkan pertimbangan dari hasil  evaluasi, maka pabrik garam industri dengan kapasitas 200.000 ton/tahun ini layak akan dikaji lebih lanjut.

The Role of Mangrove Conservation in Sustainable Tourism

The rapid growth of the tourism industry in Indonesia has encouraged innovation in the sector as each business competes to attract domestic and foreign tourists. At the same time, however, this growth is having a negative impact of environmental damage such as water pollution and soil pollution, and also producing a perceived community loss. One option is to reduce the negative impact of tourism is by encouraging the development of ecotourism activities. For example, nearby communities could be encouraged to participate in the management of mangrove conservation ecotourism areas. This study considers how such communities can work with local governments on these projects. This complements traditional beliefs within the Indonesian culture which held that ancestors entrust natural wealth to their descendants to be guarded and utilized wisely.
