Perairan di Provinsi Kepulauan Bangka Belitung merupakan perairan yang terletak di Selat Karimata. Di sebelah utara Pulau Bangka, terdapat perairan Teluk Kelabat yang berhadapan dengan Laut Natuna. Sebaliknya, Selat Sadai terletak di sebelah selatan Pulau Bangka dan berhadapan langsung dengan Laut Jawa. Penelitian ini bertujuan untuk mengetaui karakteristik parameter oseanografi di perairan tersebut yang meliputi kondisi pasang-surut, arus, dan gelombang. Data yang dipergunakan untuk menganalisis ketiga parameter oseanografi tersebut diperoleh dari Badan Informasi Geospasial (BIG). Penelitian ini akan menfokuskan pada kondisi oseanografi pada musim timur (Juli 2017) dan musim barat (Januari 2018).  Hasil analisis menunjukan pasang-surut di kedua perairan tersebut bertipe diurnal dengan kategori makro-tidal di Teluk Kelabat dan meso-tidal di Selat Sadai dengan tunggang pasang surut masing-masing 3m dan 2,5m. Selanjutnya, arah arus di perairan Teluk Kelabat dan Selat Sadai mempunyai pola yang mengikuti arah angin di tiap musimnya dan kecepatannya cenderung lebih tinggi di musim barat. Kecepatan arus berkisar antara 0.2–0.3 m/det. Untuk karakteristik gelombang, tinggi gelombang signifikan di perairan utara Pulau Bangka (Teluk Kelabat) cenderung lebih besar yaitu berkisar antara 0.1-0.5 m. Sedangkan perairan selatan Pulau Bangka (Selat Sadai) tinggi gelombang berkisar antara 0.1-0.3 m. Tinggi gelombang cenderung lebih besar ketika musim barat dibandingkan ketika musim timur.  Bangka Belitung seas is located in the Karimata Strait. In the North of Bangka Island, there are Kelabat Bay that the Natuna Sea was confronted with. Instead, Sadai Strait is located at  south Bangka Island and dealing directly with the Java Sea. This study will compare the oceanographic characteristics in both region which include tidal conditions, currents, and waves. The data are used to analyze the third oceanographic parameters obtained from the Badan Informasi Geospasial  (BIG). In this research will be focusing on the oceanographic conditions in the east monsoon (July 2017) and west monsoon (January 2018). The results of this research shows the tides in both the waters of diurnal with the category macro-tidal at the Kelabat Bay and meso-tidal at Strait Sadai with the tidal range are 3m and 2,5m . Furthermore, the direction of the currents in the waters of Kelabat Bay and Strait Sadai will follow the wind direction in every season and tends to be higher at west monsoon with the current veolcity around 0.2-0.3 m/s. For the wave characteristics, significant wave height in north seas of the Bangka Island (Kelabat Bay) tend to be larger, around 0.1-0.5m when compared with south seas of Bangka Island (Sadai Strait) around 0.1-0.3m and tend to be higher when west monsoon than east monsoon.

Pulau Bangka merupakan penambangan timah lepas pantai terbesar di Indonesia yang dilakukan oleh perusahan dan masyarakat, baik legal maupun ilegal. Hal ini menjadi mengkhawatirkan terutama akan dampaknya terhadap peningkatan sedimentasi, seperti wilayah Teluk Kelabat yang direncanakan menjadi kawasan konservasi. Tujuan penelitian ini adalah mengetahui kondisi hidro-oseanografi dan sebaran Total Suspended Solid (TSS) akibat penambangan timah di perairan Bangka terutama di Teluk Kelabat. Metode yang digunakan adalah analisis pemodelan numerik dengan menggunakan software MIKE21 untuk memperoleh data hidro-oseanografi dan model sebaran TSS dengan sumber TSS dari tiap-tiap lokasi Izin Usaha Pertambangan (IUP) melalui modul Flow Model Flexibel Mesh (FM) dan Mud Transport (MT). Verifikasi hasil model diperoleh korelasi sebesar 0,9435 dengan Root Mean Squared Error (RMSE) sebesar 0,1611 untuk pasang-surut. Tailing penambangan timah lepas pantai akan menyebabkan tingginya sebaran TSS di perairan Bangka, terutama aktivitas penambangan di perairan yang dangkal (<10 m) dan dekat pesisir (<2 mil). Sebaran TSS di perairan Bangka akan dominan terbawa ke arah Selat Bangka. Pada Teluk Kelabat, TSS bernilai sekitar 0-25 mg/L dan menyebar ke seluruh wilayah yang dapat mencapai radius sekitar 16 mil. Hasil penelitian ini diharapkan dapat menjadi rekomendasi bagi stakeholder seperti penyusunan Rencana Zonasi Pesisir Dan Pulau-Pulau Kecil (RZWP3K) di Bangka Belitung.

Daerah aliran Sungai Baturusa terdapat kegiatan pertambangan, perikanan, industri, dan tempat berlabuh kapal. Kegiatan yang dilaksanakan baik itu langsung maupun tidak langsung di aliran sungai mampu memicu potensi terjadinya pencemaran. Logam berat merupakan bahan pencemar berbahaya yang jika terdapat dalam jumlah besar karena mempengaruhi berbagai aspek dalam perairan, baik secara biologis maupun ekologi. Penelitian memiliki tujuan untuk mengetahui konsentrasi logam berat Pb dan Cd serta tingkat kontaminasi logam Pb dan Cd (CF/ faktor kontaminasi, I-Geo/ Indeks Geoakumulasi) EF/ Faktor Pengayaan) pada sedimen Estuari Sungai Baturusa, Kota Pangkalpinang. Logam berat dianalisis dengan metode SSA. Konsentrasi logam Pb dan Cd pada sedimen Estuari Sungai Baturusa belum melampaui rentang batas berdasarkan baku mutu yang ditentukan dalam ISQG dan PEL CCME 2002.

Bangka island is the biggest island in Bangka Belitung Province and located between Sumatra and Kalimantan Island. Furthermore, Bangka seas are connecting Natuna sea with Java sea and also become a important part of Indonesia Throughflow. This geographic condition makes Bangka island has a unique oceanography characteristics. However, the information of oceanography database of the Bangka waters remains limited. Thus, the purpose of this research is to develop a oceanography database in Bangka seas to support the development in these region like the zoning plan of Bangka Belitung. Focus area of this study is at the Bangka seas around Bangka Island. The characteristic of oceanography will be discuss in this study covering water quality, tides, waves, and currents. For describe those oceanography characteristic, the data obtained from field observation and numerical methods.. For the current this research using MIKE21 and also using SWAN (Simulating Waves Nearshore) software for wave model. Furthermore, the tidal data from Babel Ocean Observation Science and Technologies (BOOST) Center will be used in this discussion. In addition, the data of water quality are obtained from field observation in several sampling location. From this research, significant wave height (Hs) in Bangka seas around 0.02-1.87 meters and the currents ranges from 0.05-0.72 m/s. The direction of waves and current dominantly to the southeast when the west monsoon and head northwest when the east monsoon direction influenced by wind direction. Furthermore, tides type of Bangka seas is diurnal with around 2.3 m tidal range. For water quality, Bangka seas have around 22 o C temperature, 22-31 o /oo salinity, and pH are around 8.

The development of Information Technology makes various activities in human life undergo evolution. This dynamic condition gave rise to information system breakthroughs in response to the old system. Systems that are carried out conventionally began to be abandoned and switched to computerized systems. Apotek Sahabat is a company engaged in the trading business by providing all kinds of medicines for people who are less healthy and need medicine. However, the sales service system available at Apotek Sahabat is still using conventional methods, pharmacy officers write notes for the purchase of medicines ordered by customers. Data collection and counting of goods in the warehouse are still using the old method, warehouse officers must check one by one and write them into a book containing the stock and name of the goods. This obstacle often makes pharmacy officers feel difficult because they have to serve several customers when the pharmacy is busy being visited. The method used is a quasi-experimental method. Quasi-experimental is a research method that is used to generate data and test hypotheses that are controlled appropriately. To determine the effects, it must be designed and then tested. And in making this software, a system development method is used based on the waterfall paradigm with UML (Unified Modeling Language) with the tools used to design namely Usecase Diagrams, Swimlane Diagrams, Class Diagrams, and Sequence Diagrams while in making this application using the programming language PHP, HTML. and MySQL as a database management system. Therefore, the Sales Inventory information system is better than a manual system, which produces three actors involved in it, which makes management within the company run more effectively and efficiently and the sales system is more conducive.

This study aims to analyze the value of the density of marine debris, perceptions and participation in Temberan beach and Pasir Padi beach, as well as determine the relationship of perception and participation to the density of marine debris. This research is a type of research that is descriptive with a mixed approach (quantitative and qualitative). The study was conducted at Temberan beach in Bangka Regency and Pasir Pasir Beach Pangkal Pinang in October 2019. The sampling technique used was random sampling and purposive sampling. The data collection technique was carried out using observation technique namely sampling and questionnaire. The validity test uses the Pearson Product Moment formula and the reliability test uses the Cronbach’s Alpha formula. The results showed that the density of debris in the Temberan beach was more dominant at 10.92 pieces/meter2, while at Temberan beach 3 pieces/meter2. The results of perception and participation are different, with the Temberan beach occupying more complex waste problems. The relationship of perception and participation in the density of marine debris have a relationship that affects each other.

The rapid economic and population growth triggers a high demand for energy in Indonesia. This condition urges us to innovate in renewable energy which sustainable and environmentally friendly. One promising renewable energy is the tidal current energy which very potential in the island regions, such as Bangka Belitung Province. Kelabat Bay, which located in northern part of Bangka Island is a semi-closed waters and has a shallow and narrow gap in its center which separate Teluk Kelabat Luar (TKL) and Teluk Kelabat Dalam (TKD) region, which become the focus region in this research. This geographical condition allows potential energy amplification when the tides occur. Thus, this research aims to assess the potential energy of tidal currents as renewable energy in Kelabat Bay, especially at its narrow gap. The method used in this study was the numerical modelling using MIKE21 software and direct measurement to obtain tides and currents both in toward high tide and low tide condition. The current profile in Kelabat Bay is very influenced by the tidal which flow from TKL to TKD when toward high tide and vice versa toward low tide. The highest speed is measured at 15 meter depth on point 1 with speed up to 1.43 m/s. By this speed, it could be estimated 1494 watt of tidal current energy will be generated. This huge energy potential of tidal current at Kelabat Bay could be exploited to produce electricity in future works.
