In the business competition that increasingly tight along with the development of new technology that more advanced and modern makes Companies attempted to find the quick and appropriate strategy in marketing products to fulfill industry needs. The development of industrial era that gradually grow in the various fields, especially for heavy equipment industry that need to take a strategy in order to win the competition and to obtain larger market share. This research uses quantitative descriptive research method by describing facts and explaining the situation based on facts and figures data that exist and try to analyze the truth through the data obtained. The analytical method used is SWOT Analysis of TSI (No Industry Scale) using EFAS (external factor analysis) and IFAS (internal factor analysis) analysis. The results of this study indicate that company X in using the SWOT Without Industrial Scale puts the strategy of Strength (S)> Opportunity (O), Strategy Opportunity (O)> Weakness (W), Strength Strategy (S)> Threat (T) and Threat Strategy> Weakness (W), so that this condition that PT X is in position to utilize SO strategy which has highest score value that is = 7.6, followed by strategy ST = 6.6, WO = 6.0 and WT=4.8. From these results, the strategy undertaken by company X is to maintain the brand image strategy and penetrate the market to find a larger market share. Strengthening human resources (HR) needs to be done so that companies can add and train human resources, especially professional technicians.
Glycerol is a by-product of biodiesel production. So far, glycerol has not been used optimally. An alternative product that can be produced from glycerol is triacetin through the esterification process. Research on the review of reaction kinetics to determine the optimum conditions of the reaction still limited. Previous study also reported that the esterification process requires quite a long reaction time. Therefore, in this study ultrasonic technology will be used to accelerate the reaction of glycerol esterification with acetic acid using sulfuric acid catalyst. The purpose of this study is to study the effect of ultrasonic technology on the conversion of esterification of glycerol/acetic acid, and to observe the kinetic study of triacetin production. To answer this goal, this study uses a set of ultrasonic devices as a substitute for the esterification of conventional models. The greatest conversion results are obtained when the reaction temperature is 1000C with a mole ratio of glycerol/mole of acetic acid 1/8. The use of ultrasonic technology in theory should have a greater impact on conversion results. The reaction order obtained is order 2 with the largest k value in the mole ratio of glycerol: acetic acid 1: 8 which is 0.0006 (l.mol−1menit−1). Due to the variation of moles ratio, the ratio at 1/6 and 1/4 did not show significant changes of reaction rate, the changes are constant for both first and second order reaction. But at the mole ratio of 1/8, the reaction rate constant shows a significant different for temperature changes.
The circular economic scheme is applied to utilize the waste cooking oil from semarang barat resident area as raw material of biodiesels, the results shown that biodiesels production was able to produce 82.54% of biodiesels yields and analyzed refer to Keputusan Direktur Jendral Minyak dan Gas Bumi No.13483K/24/DJM/2006 specification including FAME concentration, Flash Point, Density, Viscosity and calorie value. Based on the analysis, the biodiesel produced has the potential as a substitute for diesel oil used for boiler fuel. This scheme is able to generate net income of IDR 135,542,430 per year from the biodiesel utilization on the difference of diesel oil utilization for boiler fuel and IDR 14,928,656 per year from crude glycerol sales.

Hiperglikemia merupakan kondisi medis yang diindikasikan dengan tingginya kadar glukosa darah. Hiperglikemia dapat menyebabkan kondisi diabetes yang dapat merusak struktur histologis jaringan hepar. Mimba (Azadirachta indica A.Juss) merupakan tumbuhan obat yang dikenal di berbagai daerah di Indonesia. Ekstrak etanol daun mimba mengandung antioksidan flavonoid yang dapat membantu dalam perbaikan jaringan hepar yang rusak. Penelitian ini bertujuan untuk menganalisis efek ekstrak etanol daun mimba dalam perbaikan struktur histologis hepar. Penelitian ini menggunakan desain Rancangan Acak Lengkap (RAL). Tikus putih (Rattus norvegicus L.) sebanyak 18 ekor dibagi menjadi 6 kelompok perlakuan dan 3 kali perulangan. Penelitian dilaksanakan selama 27 hari. P0 (kontrol normal) tikus kondisi normal diberi akuades. P1 (kontrol negatif) tikus kondisi hiperglikemi diberi akuades. P2 (kontrol positif) tikus kondisi hiperglikemi diberi glibenklamid dosis 2.25 mg/kg BB. P3, P4, dan P5 merupakan kelompok tikus hiperglikemi yang diberi perlakuan ekstrak etanol daun mimba dengan dosis masing-masing 100, 200, dan 400 mg/kg BB. Kondisi hiperglikemi tikus diinduksi dengan pemberian aloksan dengan dosis 120 mg/kgBw. Data penelitian dianalisis menggunakan uji Anova pada signifikansi 95%, sedangkan data yang tidak terdistribusi secara normal dianalisis dengan uji Kruskal-Wallis. Hasil menunjukkan bahwa pemberian ekstrak etanol daun mimba berpengaruh nyata pada parameter diameter hepatosit dan skala kerusakan hepatosit (P<0,05), namun tidak memberikan pengaruh nyata pada parameter hepatosomatik indeks (P>0,05). Kesimpulan penelitian ini adalah pemberian ekstrak etanol daun mimba (Azadirachta indica A.Juss) dosis 400mg/KgBB efektif melindungi jaringan hepar tikus putih jantan dari kondisi hiperglikemia akibat induksi aloksan Hyperglycemia is a medical condition indicated by the abnormally high blood sugar level in one’s body. Hyperglycemia usually leads to diabetes which is known to be capable of damaging the histological structures of liver tissues. Neem (Azadirachta indica A.Juss) is a well-known medicinal plant in various regions. Ethanolic extract of neem leaves contains the antioxidant flavonoid that can help repair damaged liver tissues. The aim of this research was to analyze the healing properties of the neem leaves ethanol extracts to the damaged liver tissues. This research used the Completely Randomized Design (CRD) model with a total of 18 male white rats which were divided into 6 treatment groups and 3 iterations. The research was carried out for 27 days. P0 (Normal control) the group of rats in normal condition were given distilled water. P1 (negative control) the group of rats in hyperglycemic condition were given distilled water. P2 (Positive control) the group of rats in hyperglycemic condition were given glibenclamide with the dose of 2.25 mg/kg Body Weight. P3, P4, and P5 were the group of rats in hyperglycemic conditions who were given neem leaves ethanol extract with doses each 100, 200, and 400 mg/Kg Body Weight. The hyperglycemic condition in rats was induced by administration of 120 mg/kgBw of alloxan. The findings from the research were analyzed using the Anova test at a 95% significance rate. As for the data that was not normally distributed, the Kruskal-Wallis test was used to analyze the dataset. The results showed that the administration of neem leaves ethanol extract had a significant effect on the parameters of hepatocyte diameter and the scale of hepatocyte damage (P<0.05), but did not significantly affect the parameter of the hepatosomatic index (P>0.05). The conclusion of this study was that the ethanolic extract of neem leaves with the dose of 400 mg/Kg body weight can indeed effectively protect and repair the damages induced by the alloxan-induced hyperglycemia in male white rats.
This research aims for the production of biodiesel (methyl ester) with the raw material of palm sludge oil (PSO) and perform a feasibility analysis through the parameters of Net Present Value, Internal Rate of Return (compare to bank interests rate), and Simple Payback Period on the small industrial scale 50-70 litters the biodiesel production obtained 91.30% yield from. Biodiesel can replace diesel oil as a fuel boiler for industrial use based on the quality parameters analysed, including methyl ester content, calorie value, flash point, viscosity and density.
