Abstract

Masyarakat kepulauan BangkaBelitung selain terkenal dengan pertambangan Timahnya juga terkenal dengan hasil perkebunan antara lain lada,sawit,karet dan masih banyak lagi, namun peneliti di sini memfokuskan pada suatu hasil yang lebih khusus lagi yaitu masalah perkebunan/petani sayur yang ada di kepulauan BangkaBelitung khususnya di Kabupaten Bangka Induk.masalah yang sering timbul di petani adalah waktu penyiramannya terlalu lama dan sering tidak tahu masalah kelembaban pada tanaman tersebut sehingga akan menyebabkan tanamanan akan mengalami keringan atau layu.inilah dasar peneliti membuat suatu alat yang bisa untuk menyiram secara otomatis dengan menggunakan sprinkler sebagai alat untuk menyemprotan air ke tamanaman sayur tersebut,dengan mengetahui berapa besar kelembaban yang ada pada lahan tersebut akan di instruksi alat penanda kelembaban yang akan menghidupkan air secara otomatis pada saat penyiraman.dengan menggunakan solar cell sebagai sumber energi diharapkan akan mampu menghemat pemakaian daya listrik sebagai pensuplay motor pengisap air.

Abstract

Indonesia is a developing country with a very fast industrial development, such as the power generation, oil and gas, automotive and other industries that have grown up to date. Vibration analysis is one of the analysis parameters in predictive maintenance, especially used to detect the source and symptoms of demage. In conection with this, data collection is carried out using a vibration measuring instrusment CSI 2140 by setting the Accelerometer at the data collection point for the motor and condensate pump. This research was conducted to determine the effect of vibration what will happen to the condensate pump. In order to anticipate/avoid things that will result in breakdown maintenance. of reading the vibration data of the condensate pump unit 1b on the MOV (Motor Outboard Vertical) and MOH (Motor OutboardHorizontal)positions have the highest values, namely MOV: 6.21 mm/s and MOH: 6.01 mm/s and have entered limit(under attention) based on the condensate pump data spesification are included in the category group 2 rigid 15kw<150kw at the vibration standard ISO  10816-3 and after maintenance was carried out by doing condensate unit then the vibration measurement were taken found the highest value was 1.83 mm/s on the MOV side and entered the statisfactory  limit based on ISO 10816-3.

Abstract

The bimetallic welding process is a welding process that connects two different types of metal. This study aims to determine the effect of the E309-16 electrode on the connection of two materials using smaw welding on tensile strength. The materials used were carbon steel AISI 1045 and stainless steel 304. This study used an experimental method with a penetration and filling welding process with a 60° V seam using an E309-16 electrode. The shape of the specimens in this study used the ASTM E8 standard. From the results of the tensile test research conducted, the E309-16 electrode has an influence on the bimetallic welding process on AISI 1045 carbon steel and 304 stainless steelwith a resulting tensile strength of 58.01 Kg/mm – 68.48 Kg/mm, yield strength that is produced by 35.97 Kg/mm – 37.12 Kg/mm, the resulting strain value was 12.50% - 43.00% and was able to withstand a given tensile load of 6450 Kg – 7900 Kg. and the bimetallic welding process using the E309-16 electrode has a more binding effect on the 304 stainless steel material, this is evidenced by the broken specimens in the weld area and the lower carbon content of 304 stainless steel with a carbon content of 0.042% compared to AISI steel material 1045 which has a carbon content of 0.42%.

Abstract

Lightweight bricks are concrete bricks that have a lighter specific gravity than concrete bricks in general. Lightweight concrete according to the Indonesian National Standard (SNI) 03-3449-2002 is concrete that has light aggregate or a mixture of light coarse aggregate and natural sand as a substitute for light fine aggregate provided that it does not exceed the maximum concrete weight of 1850 kg/m3 The size of the sand grain matters against the compressive strength of lightweight bricks. The method used in this study is using the Full Factorial method. The results of the compressive strength test showed that the average value of the largest sample was 60.90 MPa and the average value of the smallest sample was 6.70 MPa. As for the results of the density test, the largest average value was 6,135.36 kg/cm3. The results of the density test obtained the smallest average value of 2.968 kg/cm3

Abstract

Tofu manufacturing wastewater produces water that contains low pH. The wastewater is flowed into the river so that the water is polluted and becomes acidic. To increase the pH of the polluted water, adsorbents have been made from Laevistrombus Canarium. Laevistrombus Canarium can be utilized as adsorbents by activation. Activation is useful to increase the adsorption charge, so that the adsorption energy can be increased. The activation process is carried out using an oven with temperatures of 550 ° C, 650 ° C, and 750 ° C. The powder used is mesh 100, 150, and 200. Activated Laevistrombus Canarium powder can increase the pH of water. The results showed that snail powder can increase the pH of water polluted by tofu-making wastewater. By using the Taguchi method, the activation temperature of the adsorbent showed the optimal value at a temperature of 550°C and a powder size of 100 (149m).

Abstract

Binders play a vital role in briquette production by uniting charcoal particles into a solid form. This study aims to evaluate the effect of tapioca starch concentration as a binder on reducing the ash content of coconut shell briquettes. The binder concentrations used were 10%, 15%, and 20% of the total material mixture, with ash content testing conducted according to SNI 01-6235-2000 standards. The briquette production process involved raw material preparation, mixing, molding, and drying. The results indicated that binder concentration significantly influenced the ash content of the briquettes. Lower binder concentrations resulted in reduced ash content, with the lowest ash content of 1.52% achieved at a binder concentration of 10%. Conversely, higher binder concentrations tended to increase ash content due to residual binder that did not fully combust. This study emphasizes the importance of regulating binder concentration to enhance the quality of coconut shell briquettes as an alternative fuel source.

Abstract

The manufacturing industry, particularly in the automotive sector, galvanized steel sheets are commonly used due to their strong durability and high rigidity, making them suitable as structural components for vehicle bodies. However, the rigidity of galvanized steel sheets can be affected when formed under cold conditions. Therefore, this study aims to investigate the impact of cold forming on the natural frequency of 0.8 mm thick galvanized steel sheets. Using the Vibroport 80 device, the sheets were formed into cross grooves and then clamped onto a test fixture as part of the testing procedure. Taguchi's method was employed to analyze the data. Based on the research results using Taguchi, the Signal-to-Noise (S/N) ratio for stiffness with the "Smaller Is Better" criterion revealed that the optimal groove profile, for maximum frequency response, had a width of 12 mm, depth of 3 mm, and a frequency value of 52.45 Hz. No significant process variables or parameters were found to have a substantial impact on the stiffness or natural frequency response of the formed sheet.

Abstract

Limbah cair industri makanan umumnya menghasilkan cairan yang mengandung pH rendah. Air limbah tersebut dialirkan ke sungai sehingga air tercemar dan menjadi asam. Air dengan pH yang rendah tersebut dapat diperbaiki kualitasnya dengan menambahkan adsorben. Cangkang siput gonggong dapat digunakan sebagai adsorben dengan cara aktivasi. Aktivasi berguna meningkatkan muatan adsorpsi, sehingga energi adsorpsinya bisa dinaikkan. Proses aktivasi dilakukan menggunakan oven dengan temperatur 550°C, 650°C, dan 750°C. Serbuk yang digunakan adalah mesh 100, 150, dan 200. Metode analisis untuk mengetahui nilai optimal proses aktivasi sehingga menghasilkan karakter kualitas terbaik digunakan metode Taguchi. Hasil penelitian menunjukkan bahwa serbuk siput gonggong yang telah diaktivasi dapat meningkatkan pH air yang tercemar. Hasil optimasi dengan metode Taguchi diketahui bahwa nilai terbaik temperatur aktivasi berada pada suhu 550°C dengan ukuran serbuk mesh 150 (± 89 μm).
