Abstract

Research has been carried out with the title of the biobriquette quality mixture of coconut shell, corn cobs, and rice husk with sago flour as adhesive. The purpose of this study was to determine the quality of the bio-briquettes with a mixture of coconut shells, corn cobs and rice husks with sago flour as an adhesive. In this study the raw material used was coconut shell with the process of drying at temperatures of 3500C, corn cobs with a temperature of 1500C and rice husks with a temperature of 1200C with the composition used was 60%: 20%: 20%, 60%: 25%: 15%, 60%: 30%: 10% and 60%: 35%: 5% then sieving particle size for all 40 mesh samples, mixing using 3 grams of sago flour as bio-briquette adhesive, then bio-briquette printing and drying is done. Furthermore testing of compressive strength, moisture content, ash content, calorific value and combustion time with the results of compressive strength testing using the tool. TA.XTPlus Texture Analyzer the best characteristics obtained in the composition 60%: 35%: 5% with a value of 9.82 kg /cm2, and the best characteristic moisture content was tested in the composition of 60%: 30%: 10% with a value of 4.59%. The quality produced from the biobriquette mixture of coconut shell, corn cobs, and rice husk with sago flour as adhesive can be categorized as good. This is seen from the testing of water content, ash content and calorific value that meets the Indonesian national standard and the burning time of 152.18 minutes, except for compressive strength testing that does not equal to the quality standards of Indonesia.

Abstract

This study was to determine the effect of storage time on temperature, humidity and freshness of vegetables on different packages. This research was carried out by packing green mustard vegetables, fruit tomatoes, and potato fruit using banana leaves and charcoal and without packaging using a thermohygrometer to measure temperature and humidity. Data retrieval is done once a day at 09.00 WITA to complete. The results of this study indicate that there is an effect of storage time on the value of temperature, humidity and freshness of vegetables. The freshness of green mustard vegetables lasts longer with banana leaf packaging than those using charcoal and without packaging. Freshness for fruit tomatoes and curly tomatoes lasts longer on the packaging of banana leaves that use charcoal than without packaging and which use banana leaf packaging. old without packaging compared to packaging and charcoal.

Abstract

The research has been conducted to determine the effect of exposure to a dose of radiation to the distance and time from the source of radiation and to determine how large exposure to radiation scattering which is received by a worker or operator in the space radiology Hospital Makassar. This research uses X-ray aircraft, Surveymeter, meter, and phantom. In measurements carried out two stages namely stage first measure exposure dose of radiation to the distance the results of the research that is done on testing the safety of exposure to radiation rays -X in units of radiology Hospital cities of Makassar, then obtained a conclusion as follows based on parameters of distance and time from the source of radiation effect large against  dose of radiation exposure. A more far distance from the source of radiation the dose that is received by increasingly smaller. While the influence of the amount of time of the exposure beam of radiation that is increasingly long time irradiation then getting big too doses of radiation are obtained. Value exposure to radiation scattering which is received by the worker radiation chamber radiology Hospital of Makassar is the dose of radiation that is received by workers with long time use of radiation were the biggest received by operators XIII which amounted to 0.1769 mSv/h, while the value of the dose which is the smallest  received by the operator XI of 0.0593 mSv/h and the average dose received by the operator is 0.1570mSv/h.

Abstract

This study aims to analyze the effect of temperature variations on the capacitance of graphene material supercapacitor electrodes from bamboo material Betung (Dendrocalamus asper). The results obtained are graphene reduction can be synthesized by the hummer method which is reduced using Zn and continued with a thermal process with different temperature variations. The data obtained shows that from the GO, rGO 80 ° C, and 200 ° C rGO samples the largest capacitance value is the 200 ° C rGO sample, which is 8.87 × 10-3 F / gram with d-spacing 3.821082 Å, while the capacitance value for GO and rGO 80 ° C samples respectively 2.23 × 10-5 F / gram with d-spacing 3.668773 Å and 1.67 × 10-4 F / gram with d-spacing 3.680739 Å. This happens because the thermal effect is given, the greater the temperature given, the more pores are formed and the surface area will also be larger which results in more ion absorption and electron transfer on the electrode surface. However, if the given temperature is too large then the pore structure will be damaged and produce a low surface area. All samples that have the largest capacitance at the smallest pay rate are 10 mV / s.

Abstract

The research has been carried out by utilizing pore conch shell waste using sweet potato starch to make porous Hydroxyapatite using porogen sweet potato starch by precipitation method and to determine the bioactive properties of apatite hydroxy and the growth of apatite crystals using Simulated Body Fluid (SBF). This study used wet precipitation method. The results of the analysis  using XRD show that the HAp phase has been formed. The morphology of HAp based on SEM results shows that HAp pores modification is produced in the composition of HAp added with 20% sweet potato starch with 6 hour sonication wich results in pore size from the range 0,23-3,37 µm. This result is not correlate with the theory that the best pore modification is produced in the composition of HAp added with 30% starch. This is because there are difference characters of each sweet potato used. The result of in vitro tests on synthesis HAp samples and 7 days porous HAp have shown the growth of apatite crystals in SBF solution media (Simulated Body Fluid).

Abstract

This study aims to determine how much electrical energy or power density produced from the sago stem substrate using Microbial Fuel Cell (MFC) technology without the addition of electrolytes by adding KMnO4 and K3Fe (CN) 6 as an electrolyte solution. From the measurement results, it is obtained that the sago stem substrate sample has electrical potential or power density (mW/m2). The large power density (mW/m2) produced from the sago stem substrate using lactobacillus plantarum bacteria without the addition of an electrolyte solution was obtained at 50,082 mW/m2. For samples with the addition of 0.2 M KMnO4 and potassium phosphate buffer with pH 7, a power density value of 91,082 mW/m2 was obtained and the addition of K3Fe (CN) 6 0.2 M and sodium phosphate buffer with pH 7 obtained a power density value of 27,287 mW/m2.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh variasi suhu pengeringan cangkang telur terhadap kualitas pupuk organik. Dengan menggunakan dua metode pengujian, yang pertama pengujian menggunakan Atomic Absorption Spectrophotometry (AAS) untuk mengetahui kadar kalsium pada cangkang telur yang telah dikeringkan pada suhu yang bervariasi, yang kedua pengujian pupuk pada tanaman. Hasil yang diperoleh adalah dengan pengujian kadar kalsium dan pengujian pada tanaman menunjukkan bahwa pengeringan kulit telur pada suhu rendah tidak menurunkan nilai kadar kalsium yang terdapat pada kulit telur, begitu pula sebaliknya pengeringan dengan suhu tinggi dapat menurunkan nilai kadar kalsium kulit telur. Pada pengujian pertumbuhan tanaman meliputi tinggi batang, jumlah batang dan daun tanaman yang memiliki pertumbuhan baik adalah tanaman yang dipupuk dengan cangkang telur yang dikeringkan pada suhu 37℃ dan 50℃ dan hasil uji kadar kalsium menunjukkan pada suhu 37℃ sebanyak 1,32%, pada 50℃ sebanyak 1,06%, suhu 100℃ sebanyak 2,21% dan suhu 150℃ sebanyak 0,80%. Namun dari hasil pengujian kandungan kalsium cangkang telur pada suhu 100℃ nilai kandungan kalsiumnya lebih tinggi, karena kemungkinan pada suhu 100℃ merupakan suhu yang baik untuk digunakan dalam proses pengeringan, pada suhu ini kandungan senyawa lain dapat terurai sempurna dan kandungan kalsium meningkat.
