Abstract

Penelitian ini bertujuan untuk membaca, merekam, dan mengumpulkan data biomedik dari detak jantung dan keringat secara real time (2) untuk menampilkan data biomedik berupa detak jantung dan keringat secara real time pada monitor dan (3) untuk menyimpan data biomedik berupa detak jantung dan keringat yang telah ditampilkan oleh monitor dalam bentuk file gambar dengan eksistensi *.png.Metode pengumpulan data menggunakan teknik observasi untuk mengamati sinyal gelombang dari detak jantung berbasis Photoplethysmography (PPG) dan keringat berbasis Galvanic Skin Response (GSR). Cara kerja dari produk yaitu alat pendeteksi detak jantung (PPG) dan  pendeteksi keringat (GSR) dihubungkan pada rangkaian regulator sebagai penyuplai tegangan untuk kedua alat tersebut, kemudian alat pendeteksi detak jantung (PPG) dan pendeteksi keringat (GSR) menerima data dari pasien yang telah diperiksa maka data tersebut dimasukan  kedalam Arduino, kemudian data tersebut digabungkan dan dikelola agar data tersebut dapat ditampilkan sebagai dua gelombang sinusoidal pada layar monitor.Hasil perancangan  dapat disimpulkan bahwa sistem pengumpulan data biomedik dilakukan dengan menggunakan sinyal photoplethysmography (PPG) melalui pengambilan data detak jantung dan galvanic skin response (GSR) melalui pengambilan data keringat kemudian data tersebut diolah dalam arduino deumilanova dengan listing program yang telah dibuat untuk kemudian hasil sinyalnya dapat ditampilkan secara bersamaan pada monitor dengan menggunakan software processing dan disimpan sebagai data biomedik secara real time.

Abstract

Story and character education are two very important things in early childhood education. Storyis a method for conveying messages through an event. Whereas character education is an effortor guidance that aims to shape a child's personality. Character value in early childhood is a verybasic value that must be owned by each individual, therefore, steps to develop it through thereality of living together that make children feel the goodness of that value. One method incharacter education is through stories, in which the story is one of the expressions in the Qur'anwhich can be grouped into historical, parable, and amateur stories. The story has benefitsincluding, it can arouse the awareness of the reader or listener, be able to direct emotions, andcontain ibrah which can be used as a lesson. As with other character education methods, storiesalso have advantages and disadvantages

Abstract

Penelitian ini berhasil mengidentifikasi ketebalan lapisan tanah gambut di Parit Haji Husin II Kecamatan Pontianak Tenggara dengan menggunakan metode geolistrik tahanan jenis konfigurasi Wenner-Schlumberger. Pengambilan data dilakukan pada 5 (lima) lintasan dengan panjang lintasan masing-masing 39 m. Hasil penampang tahanan jenis 2D pada lokasi penelitian menunjukkan bahwa struktur bawah permukaan terdiri dari tanah gambut dan tanah lempung. Berdasarkan interpretasi tersebut, tanah gambut memiliki nilai tahanan jenis berkisar antara 57 Ωm sampai 288 Ωm dengan ketebalan (1,2 - 2,6 m), sedangkan tanah lempung memiliki nilai tahanan jenis 3,6 Ωm sampai 56 Ωm dengan ketebalan hingga 7,88 m.  Interpretasi tersebut telah divalidasi berdasarkan data pengeboran sampel tanah pada lintasan 1. Hasil penampang citra 3D menunjukkan lapisan tanah gambut tersebar menutupi lokasi penelitian dengan gambut yang lebih tebal dominan ke arah Barat Laut dan Timur Laut.

Abstract

Wetland water and acid mine drainage are available in South Kalimantan, Indonesia. However, “Wetland saline water (WSW)” phenomena occur in the wetland areas due to the seawater intrusion, this water which contains a high salt concentration is unsafe to be consumed. While acid mine drainage (AMD) pollution becomes an issue in the mining industry that impact human life and the environment. Salt particles could be removed by using a silica pectin membrane. Banana peel has a high pectin substance. Banana pectin (0.5wt% and 0.1wt%) was employed in silica and calcined at 300 and 400 °C. We demonstrate the silica pectin template’s performance without interlayer for wetland water and acid mine drainage desalination. Membranes were developed through a sol-gel method with silica source deposited from tetraethyl orthosilicate (TEOS) and performed by pervaporation at room temperature (~25 °C). As a result, 0.5wt% banana pectin concentration at 300 °C exhibited excellent performance with the highest water fluxes are 8.4 and 10.4 kg m?2 h?1 for WSW and AMD, respectively. Nevertheless, both membranes achieved high salt rejections up to 92%. Thereby, banana pectin as a carbon source impacts the stronger silica bond.

Abstract

The clean water crisis is increasing along with the increasing human population. Sea water is one of the largest water sources that can be utilized on the earth. However, the high salt concentration dissolved in seawater must be treated before it can use. Desalination is the directly technology for treating seawater with PVDF-TiO2 hollow fibre membrane via pervaporation process. The aim of this research was to determine the performance of PVDF-TiO2 hollow fibre membrane against variations in feed temperature in the artificial seawater pervaporation process. Method for fabrication membrane is using dry-wet spinning method. The result showed that the highest flux permeat occurred at feed temperature of 60ºC, namely 8.96 kg.m-2.h-1 with salt rejection > 92.86%. The result via SEM showed that of the membrane surface morphology, there is a white spot on the membrane surface is TiO2 because the dope solution is too thick. The PVDF-TiO2 hollow fiber membrane in this research is can be applied for seawater pervaporation.

Abstract

The water pollution caused by diamond mine activities can kill aquatic life. In this work, we used phytoremediation and filtration to treat pond water polluted by the tailings of a diamond mine located in South Kalimantan, Indonesia. Einchhornia crassipes (water hyacinth) was utilized as the biomass for the phytoremediation process. Gravel (10–15 mm) and sand (0.1–1 mm) were used as filter media in the simple filtration setup, using an up-flow system (bottom to top). In the experiment, 16 L of diamond tailing water was poured into five phytoremediation reactors (each 60 L in volume), which were then tested over seven days. A pretreatment analysis of the tailings water showed that its biochemical oxygen demand (BOD) of 8.9 mg L−1 and chemical oxygen demand (COD) of 22 mg L−1 exceeded the national maximum standards of 2 mg L−1 and 10 mg L−1, respectively. The experimental results demonstrate that both phytoremediation and filtration could increase the dissolved oxygen concentration (4.7 mg.L−1) and reduce the BOD (3.2 mg.L−1), COD (6.5 mg.L−1), Fe (0.6 mg.L−1), Mn (0.16 mg.L−1), and ammonia (0.63 mg.L−1) concentrations from those measured in the raw diamond-mine-tailings water. The phytoremediation performance was better than that of filtration. The COD values were successfully reduced to the permissible limit, although the other parameters still failed to meet the government water quality regulation requirements.
