Abstract

Kantor ataupun instansi yang menggunakan jaringan nirkabel atau hotspot dengan banyak pengguna memerlukan manajemen pengguna. Penerapan manajemen pengguna ini bertujuan untuk mempermudah admin dalam mengkonfigurasi jaringan nirkabel tersebut. Admin juga memerlukan sistem monitoring untuk memantau akses jaringan nirkabel. Hal ini dikarenakan jaringan nirkabel mempunyai kerentanan keamanan. Oleh sebab itu, diterapkan pengaturan sistem keamanan dengan Server AAA  (Authentication, Authorization, Accounting) pada pengguna jaringan nirkabel. Sistem keamanan tersebut akan melakukan pengecekan otentikasi, otorisasi, dan audit atau accounting pada pengguna. Dukungan server AAA dalam pengaturan jaringan nirkabel ini menggunakan teknologi RADIUS dengan penggunaan server di sistem operasi Debian. Keberadaan server ini bertujuan untuk menyimpan data pengguna jaringan nirkabel. Sedangkan, teknologi RADIUS dipilih karena mendukung pengaturan multi user dan multi roaming. Selanjutnya, pada router mikrotik dilakukan instalasi API bot telegram untuk berperan sebagai sistem monitoring jaringan secara real time. Hasil dari penerapan manajemen user dan sistem monitoring jaringan nirkabel tersebut menjadikan network administrator dapat memantau user, jam login, jam logout, dan alamat IP melalui aplikasi Telegram.

Abstract

The method used for the Ion Exchange process to determine the characteristics of the zeolite is refluxing the zeolite using a 4 M LiCl solution for 36 hours at a temperature of 72℃ and calcined at a temperature of 400℃ for 10 hours. XRF characterization results showed natural zeolite Lampung had moderate Si/Al levels with 8.97 and 8.79 for those given lithium, while zeolite 13X had low Si/Al levels with 4.31 and 3.77 for those given lithium. The XRD results show that Lampung's natural zeolite is clinoptilolite and 13X zeolite is NaX. The results of the adsorption test using the PSA tool, namely for natural zeolite Lampung, the highest oxygen value was 21.3% and that was given lithium at 21.2% for the single bed and double bed types. For zeolite 13X, the highest oxygen value was 22% and that given lithium was 24% for the single bed type, and for the double bed type the highest oxygen value was 21.8% and those given lithium were 24.9%.

Abstract

Combustion of corn leaf as a model of biomass from agricultural waste is a simple way to obtain the energy. It produces a low-value by-product of ash and is rich in silica that can become a precursor for zeolite production. In this study, acid-treated corn leaves combustion was performed to produce high purity silica (SiO2). The diffraction pattern suggested that the extracted silica was amorphous without the impurities phase. Additionally, the nitrogen isotherm indicated that the material was highly mesoporous silica with a total surface area of 200 m2/g. The hydrothermal method was then applied with a composition molar ratio of 1.25SiO2:1Al2O3:5Na2O:250H2O to synthesize zeolites from the silica. The temperature and time effect on the hydrothermal zeolite’s synthesis was investigated. The diffraction pattern shows that high crystalline zeolite Na A-X was produced at temperatures of 100°C and 8 h hydrothermal time. According to nitrogen physisorption analysis, the zeolite Na A-X consisted of micropores with a total surface area of 270 m2/g. The morphology of zeolite Na A-X was cube for the Na-A and octahedral for the Na-X. The hydrothermal temperature and time highly affected the zeolite formed. This research suggested that the ash waste could be valorized through conversion into a high economic value zeolites.

Abstract

Rice bran is one of the parts produced from rice milling, this part contains more than 20% dietary fiber. Rice bran has many useful substances, but its use is hampered by bran itself because it is easily damaged due to hydrolytic and oxidative activity. To overcome this problem, another method is needed so that the Bekatul can last longer. A drying machine is a machine used to reduce the air content in a substance. The aim of this research is to design the structure of a rice bran drying machine with various types of selected materials to obtain stress and cooling values. The method used in this research is finite element simulation. The materials varied in this research were AISI 304, Aluminum alloy 6061 and Galvalume Steel with thickness 0.7 mm. From the test results, it can be stated that all materials are safe to be used as the main material for making structure. However, there is one best material that produces the best maximum stress values and the smallest displacement, namely Galvalume Steel

Abstract

Agriculture waste-based materials have considerable potential as wood-based particleboard alternatives. It has been produced abundantly from nature and considers an eco-friendly material. One of the enormous resources is the paddy by-product, rice straw (about 500 million tonnes per year worldwide). In this work, the mechanical properties of rice straw-based particleboard are predicted easily and quickly using the sessile drop method.  Rice straw was crushed into 2-5 mm diameter powder-like materials, and corn starch was used as the binder. The rice straw particleboard was formed under a hot press machine (5 MPa, 180°C and 120 minutes). Conventionally, the sample mechanical property was tested through Universal Testing Machine (UTM). Unfortunately, the process is costly and difficult to access. It is necessary to have a rapid and low-cost presumption of the mechanical particleboard properties toward more efficient manufacturing. This work proposes a simple sessile drop method to indicate particleboard mechanical properties. Multiple linear regression was performed to see the correlation between sessile drop and UTM testing. It was found statistically that the sessile drop method could be used as an early prediction of particleboard mechanical properties.
