Beberapa model penanganan keamanan pada teknologi wireless dapat dilakukan, seperti menyembunyikan SSID, menggunakan enkripsi WEP, WPA-PSK, atau WPA2-PSK, serta menerapkan MAC filtering dan captive portal.Tujuan penelitian ini adalah untuk mengetahui kelemahan pada jaringan dengan menggunakan alat seperti Nmap dan Hping3. Nmap merupakan alat yang powerful, portable, dan mudah digunakan untuk men-scan jaringan besar, sedangkan Hping3 berguna untuk memeriksa kondisi komputer dan port-portnya serta dapat mengirimkan paket TCP, UDP, atau ICMP.Berdasarkan percobaan menggunakan Wireshark, ditemukan adanya serangan DDOS Ping of Death yang dilakukan oleh alamat IP 192.168.1.1 menyerang komputer dengan alamat IP 192.168.1.2 yang menggunakan sistem operasi Windows XP. Dengan mengetahui kelemahan pada jaringan, langkah-langkah untuk mengatasi kelemahan tersebut dapat dilakukan untuk meningkatkan keamanan jaringan internet yang pada dasarnya kurang aman karena sifatnya yang publik dan global.","PeriodicalId":302680,"journal":{"name":"Jurnal Sains dan Teknologi (JSIT)","volume":"112 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Konsentrasi rata-rata tahunan PM10 di Indonesia melebihi ambang batas yang ditetapkan oleh WHO. BNPB menjelaskan bahwa CaO menjadi teknologi modifikasi cuaca dalam mengatasi kebakaran hutan yang mengandung PM10. Cangkang tiram merupakan salah satu penghasil CaO hingga 85%. Tujuan dari penelitian ini adalah agar mampu merancang teknologi filtrasi PM10 berbahan dasar kalsium oksida limbah cangkang tiram bertenaga surya terintegrasi Internet of Things yang efektif dan efisien. Metode penelitian ini dimulai dari studi literatur, perancangan, pembuatan, pengujian, hingga evaluasi kinerja alat. Hasil pengujian menunjukkan filter CaO dapat memfilter PM10 bahkan PM1 dan PM2,5 dengan efisiensi sebesar 78±0,047%. Hasil uji kelistrikan menunjukkan adanya penambahan tegangan sebesar 8,68 ± 0,19 V tiap jam dengan pengisian aki selama 2,8 jam. Hasil uji morfologi filter CaO terlihat adanya pengotor (PM10) yang menempel pada permukaan filter. Dapat disimpulkan bahwa teknologi filtrasi ini cukup efektif dalam memfilter PM10. \u0000Kata Kunci: Cangkang Tiram, Filtrasi, Kalsium Oksida, PM10, Polusi Udara \u0000  \u0000Abstract \u0000Particulate matter 10 (PM10) is a type of harmful pollutant. The annual average concentration of PM10 in Indonesia exceeds the threshold set by World Health Organization (WHO). National Disaster Management Authority (NDMA) explained that calcium oxide (CaO) is the weather modification technology in dealing with forest fires containing PM10. Oyster shell is one of the producers of CaO that can produce up to 85%. The purpose of this research is to be able to design effective and efficient tools to obtain PM10 filtration technology based on calcium oxide from oyster shell waste that is solarpowered and integrated with the Internet of Things. The research method starts with a literature study, design, manufacture, and testing to evaluate the tool’s performance. The test results show that the CaO filter can filter PM10 and even PM1 and PM2,5 with an efficiency of 78±0,047%. The results of the electrical test show that there is an additional voltage of 8,68±0,19 V per hour with 2,8 hours of battery charging. The results of the morphology test of the CaO filter after filtering PM showed the presence of white spot impurities (PM10) attached to the filter surface. It can be concluded that filtration technology is quite effective in filtering PM10.   \u0000Keywords: Oyster Shell, Filtration, Calsium Oxide, PM10, Air Polution","PeriodicalId":302680,"journal":{"name":"Jurnal Sains dan Teknologi (JSIT)","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141824745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dalam hal ini, failover menjadi solusi penting dengan memungkinkan perpindahan otomatis antara jalur utama dan jalur cadangan, mengurangi waktu henti pada jaringan. Teknologi netwatch dapat digunakan untuk mengimplementasikan failover secara otomatis tanpa mengganggu kualitas koneksi. Penggunaan perangkat router Mikrotik juga memberikan fleksibilitas dengan fitur-fitur seperti fungsi dasar routing dan kemampuan sebagai gateway.

Data collection techniques through observation, interviews, and documents related to product defects and mold damage in the injection molding process and corrective actions. The data were analyzed using data reduction, data presentation, and conclusion drawing methods. The results of the study show that injection molding has many advantages when compared to other plastic manufacturing methods, but in the process there are various defects in the plastic products produced. Based on the FMEA analysis, a number of product defects occur due to several factors, such as Bending, Gas Mark, Silver, Flash, Under Cut, Crack, Flow Mark, Scratches, Burn Mark, and Short Mold. Gas Mark has the highest risk priority number (RPN) value of 75. The problem of defects due to gas marks occurs in the housing panel components produced by PT. Patco Elektronik Teknologi. The company took corrective action NG Gas Mark on the housing panel product by means of mold maintenance and gas vent making by the mold shop for the cavity and ejector pin parts.
