Abstract

A lot of heat energy can be tap to produce electricity by converting the heat and enthalpy to move a steam turbine cycle, or usually known as Rankine Cycle. But steam cycle has to have a high temperature and high enthalpy, so lower temperature and lower enthalpy source such as geothermal brine water, solar thermal, and waste heat gas cannot be tap to produce electricity. These potential belongs to ORC or Organic Rankine Cycle. ORC has no need to utilized high temperature and enthalpy, it can use temperature as low as 80ºC instead of 170ºC or more. By utilizing ORC system, these sources is open to produce electricity. These days a lot of research for ORC is done either by simulation or by experiment and the source is also varied. For this case, the source is geothermal brine water. The design of ORC begins with calculating the overall ORC heat balance using Cycle Tempo. Thus the duty of preheater, evaporator, turbine, condenser, pump, and cooling tower can be obtained. Then using working fluid n-pentane, we calculate and optimized the thermal efficiency. After that, every individual equipment is designed and calculated by using HTRI. Design optimization which had been obtained then used as reference to do the experiment. Unfortunately, the data from the latest experiment showed that the temperature from the geothermal brine water has not met requirement yet. Therefore, further experiment has to be done with some improvement to the system.

Abstract

Batik waste can increase water characteristics such as turbidity, color and Total Suspended Solid (TSS). A technique for separating Batik from the liquid so that its turbidity, color and TSS decrease is needed. Flotation studies have been conducted using electrolysis to produce the bubbles to separate waste synthetic dye staining result of Batik from the bulk liquid. Research carried out by electrolysis with 316L stainless steel electrodes, inside an acrylic pipe with a height of 100 cm, and 8,4 cm in diameter with a voltage 15 V. Solid aluminum sulfate as a reagent was added to coagulate Batik waste as much as 1 gram per 10 ml of Batik waste. Batik waste was mixed with distilled water beforehand. Frother used was pure ethanol as much as 0.1% v/v. From the research it was discovered that flotation of Batik waste can be used for Batik waste separation with the addition of alum. Alum was proved capable of acting as collector in this type of waste separation. Ethanol as frother used was proved capable of making stable froth and increases the separation efficiency.

Abstract

Penggunaan sinar matahari sebagai sumber energi panas (khususnya di indonesia) memiliki banyak keterbatasan. Keterbatasan tersebut antara lain, energi panas dari matahari hanya tersedia di siang hari dan tidak optimal saat mendung dan hujan. Oleh karena itu diperukan pembangkit kalor sebagai penunjang, yang dapat menaggulangi kelemahan sistem yang ada. Ketel merupakan salah satu Solusi alternatif sebagai penunjang operasi sistem ORC saat cuaca mendung, hujan atau saat malam hari. Ketel berfungsi sebagai pemanas air pengganti energi panas matahari. Suplai air panas ke epavorator yang semula dihasilkan dari solar kolektor diganti dengan air panas yang berasal dari ketel. Sumber panas untuk ketel berasal burner biomassa. Pengujian ketel dilakukan dengan memvariasikan tiga debit yang berbeda yaitu: 7 liter/menit, 24 liter/menit dan 43 liter/menit. Hasil pengujian dengan debit 7 liter/menit, 24 liter/menit dan 43 liter/menit menghasilkan ?T rata-rata berturut-turut sebesar 10,4 OC, 0,46 OC dan 0,37OC sedangkan Effisiensi ketel maksimum terjadi pada debit 7 liter/menit, pada yaitu sebesar 0,032%. Dari rancangan yang dihasilkan dan pengjian yang dilakukan ketel mampu berfungsi sebagai pembangkit atau penyuplai panas di sistem ORC untuk menggantikan solar collector ketika sumber panas dari iradiasi matahari tidak diperoleh.

Abstract

Peningkatan kebutuhan pangan tidak hanya pada jumlah melainkan kualitas. Untuk menjaga kualitas buah hasil produksi pertanian diperlukan kegiatan pemanenan pada tingkat kematangan yang merata. Umumnya tingkat kematangan buah dalam suatu pohon tidak merata sehingga diperlukan pemanenan yang selektif. Pemanenan dengan tenaga manusia seringkali menghasilkan buah yang dipanen tidak matang secara merata, oleh karena itu dibutuhkan suatu alat yang mampu melakukan pemanenan secara selektif. Robot pemanen diharapkan mampu memanen secara selektif sehingga dieroleh hasil pemanenan dengan tingkat kematangan yang merata. Salah satu bagian terpenting dalam kesuksesan pada suatu robot pemanen adalah manipulator. Fungsi manipulator yaitu untuk memposisikan end-effector untuk menjangkau target buah yang akan dipanen. Kesalahan dalam menjangkau target dapat menyebabkan kegalalan robot dalam memanen. Pengendalian pergerakan manipulator menggunakan pemrograman LabView dengan Ni-Daq 6009 untuk menghubungkan manipulator ke perangkat komputer. Pengujian dilakukan dengan mengukur besar simpangan ujung manipulator terhadap koordinat target. Manipulator telah berhasil dibuat dengan tiga derajat bebas yang terdiri dari dua rotational joint (joint 1 dan joint 2) serta satu perismatic joint (joint 3). Rata-rata simpangan manipulator pengujian tanpa beban sumbu x 13.85 mm dengan ketepatan 95.70 %, sumbu y 15.05 mm dengan ketepatan 92.31 %, dan sumbu z 3.2 mm dengan ketepatan 99.42%.

Abstract

When a car is parked during daylight, later it is found that the car will be very hot and need some times from start up until reach the steady state condition or the thermal comfort achieved. This study presents a thermal comfort’s theoretical measurements based on the experiment on a car which using engineered window film. The experiments were performed in order to determine the heat and mass transfer between the body and the environment (car compartment). During experiment, the changed temperature of five body segment (forehead, left arm, right arm, hand and back); car compartment’s temperature; relative humidity and air velocity were measured. Based on the heat balance equation on human, the changes in convective, radiative, conductive, evaporative heat loss; heat loss from respiration; skin wittedness and thermal comfort indices were calculated. As a result, in the first 30 minutes, the film able to reduce compartment temperature until 5.2° C, it makes the thermal comfort achieved in less than 10 minutes.
