Abstract

Optimalisasi daya yang dihasilkan sel surya dapat dilakukan dengan cara selalu menjaga arus dan tegangan pada titik maksimum. Salah satu upaya untuk mencapai titik daya maksimum ini adalah dengan menggunakan metode Maximum Power Point Tracking (MPPT) berbasis logika fuzzy. MPPT logika fuzzy diterapkan sebagai sistem kendali operasi pada konverter peningkat tegangan dc (dc – dc boost converter). MPPT logika fuzzy berfungsi sebagai pengatur tegangan referensi yang mengendalikan besarnya duty cycle yang diterapkan pada sistem switching transistor boost converter. Pada penelitian ini ditampilkan pemodelan sistem transmisi daya sel surya berbasis MPPT logika fuzzy. Sebanyak 16 modul sel surya disusun menjadi susunan 8 seri dan 2 paralel. Pada susunan ini sistem sel surya dapat menghasilkan daya maksimum sebesar 3203 watt. Pada hasil simulasi yang dilakukan didapatkan bahwa MPPT logika fuzzy dapat bekerja optimal pada suhu 35oC dan irradiasi 800W/m2. Pada kondisi ini sistem sel surya dan MPPT logika fuzzy memiliki selisih tegangan 0.37%. Namun, peningkatan daya maksimum terjadi pada suhu 40 oC dan irradiasi 950 W/m2 dengan besar peningkatan daya 33.94%.   Kata kunci : MPPT logika fuzzy, sel surya, boost konverter, tegangan referensi.

Abstract

Spirulina plantesis is a cyanobacteria that has many purposes such as for cosmetics, and food industry. In addition, Spirulina platensis can accumulate polyhydroxybutyrate (PHB), a type of bioplastic. This review discussed the potency of Spirulina platensis as a source of bioplastics and cosmetics. From the review, Spirulina contained bioactive compound, C-phycocyanin, which can inhibit cell damage and is very potential to be applied for cosmetics. The PHB content in Spirulina tends to be small compared to other microalgae. To reduce the cost of PHB from Spirulina, the biorefinery concept can be applied, by recovery the bioactive components (C-phycocyanin), while the residue can be used as a source of PHB.

Abstract

Container crane atau derek kontainer membutuhkan transformator untuk mengatur tegangan sesuai dengan spesifikasi tegangan dari motor-motor listrik yang menggerakkan derek tersebut. Dalam pengoperasian transformator, timbul arus mula yang mengalir melalui transformator pada saat motor-motor listrik mulai dinyalakan. Meskipun durasi munculnya arus mula tidak lama, namun memiliki beberapa dampak yang dapat mengganggu pengoperasian peralatan. Salah satunya adalah timbulnya jatuh tegangan. Pada penelitian ini dilakukan simulasi kondisi arus mula serta arus pada kondisi tunak pada derek, serta menganalisis dampak dari arus tersebut terhadap jatuh tegangan pada sistem. Simulasi dilakukan dengan menggunakan perangkat lunak analisis sistem tenaga. Pada perangkat simulasi, keempat jenis motor yang menggerakkan derek kontainer yaitu motor hoist, motor boom, motor gantry dan motor trolley dinyalakan secara bergantian untuk melihat respon sistem pada masing-masing penyalaan. Hasil simulasi menunjukkan terdapat durasi jatuh tegangan yang tidak memenuhi standar dari IEC. Penambahan kapasitor sebesar 806.400 VAR dilakukan untuk memastikan bahwa jatuh tegangan yang terjadi dapat memenuhi standar dari IEC

Abstract

Structured Query Language (SQL) is a command language that allows users to access database information. Ordinary people generally donot know how to make queries with SQL to a database. The chatbot is acomputer program developed to interact with its users via text or voice. In this study, chatbots were developed to help and facilitate users intheNatural Language to Structured Query Language (NL2SQL) process tosearch for information in an Academic Information Systemdatabasewith semantic parsing using a rule-based method that accepts input inthe form of interrogative sentences or order. In the Natural Language toStructured Query Language (NL2SQL) process several problems arise, namely input problems with unique parameters for the knowledge base, and slow searching or translation processes, which make Natural Language to Structured Query Language (NL2SQL) inef icient, problems This problem will be solved using a semantic parsingapproach using a rule-based method that is proven to be ef icient insolving issues such as the Natural Language to Structured QueryLanguage (NL2SQL) process. The results showed that the semanticparsing approach using the rule-based method succeeded in obtainingan accuracy rate of 96.72% using 122 test data in the formof questionsentences or command data about the Academic Information Systemof the Department of Informatics Engineering, Sriwijaya University inIndonesian, and an average execution time of 50.68 milliseconds. seconds or 0.05 seconds.
