Nikel merupakan logam transisi yang berwarna putih keperak-perakan dan memiliki sifat yang keras, ulet dan sedikit ferromagnetis. Pada penelitian ini dilakukan pelindian nikel laterit dengan H2SO4 untuk menganalisis kandungan unsur Ni, preparasi dilakukan dengan drying, grinding dan kemudian sizing. Hasil preparasi dilakukan uji ED-XRF untuk mengetahui unsur yang terdapat dalam bijih tersebut. Pelindian kemudian dilakukan dalam tabung reaktor dengan bijih nikel ukuran kurang dari 150 mesh sebanyak 60gram dan 300 ml larutan H2SO4 1,4 M, proses pelindian dilakukan selama 3 jam dengan kecepatan pengadukan 320 rpm dan pada suhu 80oC. Larutan kaya hasil pelindian dilakukan uji AAS untuk mengetahui kadar unsur Ni. Pada uji ED-XRF didapatkan Ni sebesar 8,892 % dan NiO sebesar 4,961 % sedangkan pada uji AAS diketahui kadar nikel dari hasil pelindian nikel laterit yaitu sebesar 3458,25 mg/L.

Gas Engine Power Plant (PLTMG) is a type of power plant that uses dual fuel, namely LNG (liquid natural gas) and BBM (fuel oil). Along with the continuous operation of the Ambon Peaker PLTMG unit. So do not rule out that the engine performance will decrease. The decrease in engine performance will affect the power supply of electrical energy to the electricity demand network. In order to maintain a reliable, safe, and efficient electricity supply. So the performance of the engine performance will always be monitored regularly. This is done so that the performance of the engine performance is always properly monitored. One of the performances to assess the performance of the Ambon Peaker PLTMG unit is by carrying out a Performance Test. The method used in industrial practice activities carried out at the Ambon Peaker 30 MW PLTMG is practical work in the form of field research.

Drug abuse occurs because of promiscuity and lack of education about the dangers of drug use. The increasing cases of drug abuse that occur in the community make it quite difficult for the government to overcome this. Therefore, the existence of a drug-free or shining program will certainly have an effectiveness that aims to provide education to the community, especially the younger generation about the dangers and impacts of drug abuse. The method used in this program is through socialization activities using participatory methods, lectures and discussions. The process of this socialization activity was in the form of delivering material from the sources of the City National Narcotics Agency and continued with discussion activities. The results of this program are useful for making the younger generation as pioneers of the nation's successor to be clean from drugs.

In this final project the author discusses the problem entitled "Design of Smoke Detector and Room Temperature of SAP ERP Server at PT Apac Inti Corpora". This design aims to support the improvement of the security system in the server room with smoke and temperature detectors and microcontroller-based automatic countermeasures. Against the background of problems with sensors and countermeasures systems in the server room and lack of insight into sensor installation. This tool uses a gas sensor MQ-2 as a smoke detector, a DHT-11 sensor as a temperature detector, Arduino as a microcontroller that controls I/O, buzzer and LED as an alarm, a fan as a temperature controller, and an LCD to display conditions in the room. The output of the MQ-2 and DHT-11 sensors will be processed in a programmed microcontroller so that it can display conditions on the LCD. This tool will turn on the alarm and fan if smoke and high temperature are detected at the specified conditions.

Penyakit degeneratif merupakan penyebab terbesar kematian di Indonesia. Jumlah kematian akibat penyakit tersebut terus meningkat. Hal tersebut disebabkan karena sebagian besar penyakit diawali oleh adanya reaksi oksidasi yang berlebih dalam tubuh. Reaksi oksidasi yang terjadi setiap saat dalam tubuh dapat menyebabkan terbentuknya radikal bebas. Substansi untuk mengurangi terjadinya pembentukan radikal bebas adalah antioksidan. Tanaman kemuning merupakan salah satu tanaman yang dapat dimanfaatkan sebagai sumber antioksidan alami. Tanaman kemuning memiliki berbagai kandungan senyawa diantaranya adalah fenol, kumarin, tanin dan flavonoid. Senyawa-senyawa tersebut yang mempunyai kemampuan untuk mengurangi radikal bebas. Tujuan penelitian ini adalah untuk mengetahui kadar flavonoid total dan aktivitas antioksidan pada fraksi etil asetat daun kemuning. Metode penelitian dalam penentuan kadar flavonoid total dilakukan secara spektrofotometri UV-Vis dengan pereaksi AlCl3 sedangkan aktivitas antioksidan ditentukan dengan metode DPPH dengan pembanding kuersetin. Hasil penelitian menunjukkan fraksi etil asetat daun kemuning mengandung senyawa fenol, tanin, saponin dan flavonoid. Fraksi etil asetat daun kemuning mengandung kadar flavonoid total sebesar 10,021% dan memiliki aktivitas antioksidan dengan nilai IC50 sebesar 83,222 ppm. Penelitian ini menunjukkan bahwa fraksi etil asetat daun kemuning memiliki potensi sebagai antioksidan yang kuat.
