It takes a good maintenance management at any company to be able to run the production process effectively and efficiently. However, in practice often attempt maintenance or repair only be a waste, because the maintenance team does not know clearly the problems that occur and the factors. The purpose of this study was to measure the value of Overall Equipment Effectiveness (OEE), determine the magnitude of each factor of six big losses that affect the effectiveness of the defekator I machine, and an analysis of the factors that a top priority as the basis for repairs. In this study the method used Overall Equipment Effectiveness (OEE), and OEE six big losses to measure the performance of the machine for six months and to determine the factors of the six factors in the six big losses that give the most impact on the effectiveness of the defektor I machine. Based on the results of data processing, Overall Equipment Effectiveness value defekator I machine in purification station PT. Perkebunan XY, the ideal situation is achieved only in August and October with OEE value of 85.53% in August and 85.29% in October. Meanwhile, in June, July, September, and November OEE values are respectively 84.87%, 80.47%, 84.63%, and 76.89%. The results of the calculation of the six big losses, it is known that loss and rework loss breakdown is a factor with the largest percentage for the low effectiveness of the defekator I machine with a percentage of 63.57% for the breakdown loss and rework a loss of 24.23%. OEE and OEE value of six big losses are the basis for the provision of the proposed improvement.

Transformator Daya merupakan suatu peralatan yang sangat vital yang berfungsi menyalurkan energy listrik dari tegangan tinggi ketegangan rendah ataupun sebaliknya dan tidak pernah lepas dari gangguan. Adanya gangguan yang terjadi pada transformator dapat menghambat proses penyaluran energy listrik kepemakai (konsumen). Karena itu, system proteksi yang handal sangat dibutuhkan untuk melindungi transformator dari gangguan hubungan singkat yang diamankan oleh Over Current Relay yang digunakan adalah type SPAJ 140 C merupakan tipe salah satu relay proteksi cadangan yang digunakan oleh EMP Malacca Strait SA untuk menjaga transformator (PT-110) dengan rating tegangan 13.8/0.48 kV dengan daya 1250KVA dari gangguan hubungan singkat. Penelitian ini adalah untuk mendapatkan settingan dari Over Current Relay yang disebabkan oleh gangguan pada transformator daya yang digunakan . Dari hasil penelitian didapatkan besar arus gangguan fasa ketanah yang mengalir sebesar 9375 A dan setting waktu Over Current Relay 0.24 detik. Nilai arus gangguan yang mengalir pada transformator tersebut merupakan nilai yang besar, maka relay OCR pun bekerja diwaktu yang cepat.

Sugar palm is a commodity that has the potential to be developed. Sugar palm is developed to produce various products and raw materials for derivative products. Currently, there is a lot of morphological diversity of sugar palm plants found in the field. Presently, identification of various types of sugar palm morphologically in Banten Province is still limited. Sugar palm in Banten Province is found in various locations, such as in Lebak. This study aimed to determine the characteristics of Aren seedlings originating from Lebak Regency. The hypothesis in this study is that there are several characteristics of palm seedlings originating from Lebak Regency. This research was conducted in August 2019 - November 2019 located in Green House, Cinanggung Village, Serang City, Banten Province. This study uses a descriptive method, through a quantitative approach with data analysis and interpretation, and conclusion. The observation parameters in this study were: Plant Height (cm); Number of leaves per plant (strands); Leaf width (cm); Leaf length (cm); stem diameter (cm); Leaf color. The results showed that Aren from Lebak Regency aged 1 year have an average plant height of 28.1 cm, a pinnate leaf shape and a thick like a palm leaf, with an average number of 1 leaves, an average leaf length of 16.4 cm, and an average leaf width of 6.8 cm, with dark green leaf color. The stem diameter has a strength correlation with plant growth level like as plant height, the higher the plant. The greater the stem diameter obtained in this study is 2.19 cm.

Silica particles had been successfully separated and extracted from rice husk by using solution of sodium hydroxides (NaOH) as solvent and were characterized with SEM-EDX. The data SEM-EDX showed that the extracted component of the rice husk contained 79,55% (w/w) of silica as the primary component. In order to understand the adsorption capacity of silica in removing free fatty acids (FFA) which were recognized as the contaminants in biodiesel., the profile of time dependence and silica amount in the adsorption process had been investigated in this study. The results indicated that the adsorption process showed optimum condition at 30 minutes with the free fatty acids (about 90,64%) of adsorption). Moreover, the adsorption capacity of silica to those impurities contaminated in biodiesel was proportional to the amount of adsorbent used in the experiment. Finally, biodiesel with less FFA was produced, and the FFA residues remained in the biodiesel were 0,58 mg/g.

Polyurethane membrane made from Rubber Seed Oil has been produced within this research. Rubber seed oil has the hydroxyl number of 40,33 mg/g and the iodine number of 154,05 g/g which can be used as resource clusters; -OH, in order to make polyurethane. Rubber seed oil can react with hexamethylene-1.6-diisocyanate (HDMI) as another resource cluster, which is -NCO. The production of polyurethane membrane is done by variating the composition of rubber seed oil and HDMI, with the variations of 5:1; 5:3; 5:4; 5:5 dan 5:7 (v/w) and the polymrization temperature of 90-100°C and the curring temperature of 165-170°C. The optimal polyurethane membrane is produced on the composition of 5:4 v/w which is homogenous, dry, quite elastic and is yellowish brown in colour. The IR results showed that there were urethan bonds formed (N-H on ν = 3300-3400 cm-1) and the TGA results from polyurethane membrane showed that there were two decompositions on 394,5oC dan 458,6oC.
