ABSTRAK PT. Mifa Bersaudara sesuai dengan rencana produksi pada tahun 2018 akan melakukan coal sales sebesar 5 Juta Ton. Dengan target sales yang besar tentunya di butuhkan support yang besar dari unit-unit produksi. Maka dari itu unit operasional coal getting yang menggunakan OHT pada tahun 2017 diganti menjadi 30T class dengan jumlah yang lebih banyak. Akibat peningkatan produksi pada tahun 2018, perlu dilakukan improvement pada crusher FC01 dan FC02. Crusher FC01 dengan kapasitas produksi 750 tph dengan actual average year to date pada tahun 2017 hanya sebesar 342 tph dan FC02 dengan kapasitas produksi 450 tph dengan actual year to date hanya sebesar 350 tph. Ada beberapa parameter yang mempengarui productivity crusher FC01 dan FC02 yang tidak tercapai, yaitu feeding batubara yang masih kurang dan jarak waktu dumping antar hauler yang masih besar. Untuk meningkatkan productivity crusher FC01 dan crusher FC02 perlu dilakukan re-engineering pada area hopper agar dapat menerima feeding yang lebih besar dan perbaikan area manuver agar dapat diterapkan metode double dump. Langkah yang diambil yaitu dengan penambahan wings pada area hopper crusher FC01 dan penambahan stopper pada hopper crusher FC02 agar dapat dilakukan teknik double dump untuk meningkatkan productivity masing-masing crusher. Hasil dari project ini yaitu adanya perubahan area manuver di area dumping hopper FC01 dan FC02 yang menghabiskan biaya sebesar Rp196.215.000,00 dan terdapat perbaikan pada area hopper FC01 dengan menambahkan wings pada sisi kiri dan kanan hopper serta penambahan stopper pada area hopper FC02 yang menghabiskan biaya sebesar Rp166.140.000,00 dengan total keseluruhan biaya sebesar Rp362.355.000,00. Setelah diterapkan metode double dump pada crusher FC01 dan FC02, productivity crusher FC01 meningkat menjadi 500 tph dan FC02 meningkat menjadi 354 tph dengan total proyeksi revenue yang didapat pada akhir tahun 2018 sebesar $36,672,864. Kata kunci : crusher, double dump, productivity, cost  ABSTRACT PT. Mifa Bersaudara in 2018 planned to conduct 5 million tons of coal sales. With a large sales target, a good support from the production units is a must. Therefore, the coal getting operation that used to utilize Off High Way Trucks (OHT) in 2017 replaced those units with 30T class trucks with more units. As a result of increased production plan in 2018, improvements for the FC01 and FC02 crushers need to be done. FC01 crusher has a production capacity of 750 tph with an actual year to date in 2017 averaged in 342 tph. FC02 with a production capacity of 450 tph with an actual year to date figure averaged in 350 tph. There are several parameters that affect the productivity of the FC01 and FC02 crushers. Some of the parameters have not been achieved, such as the lack of coal feeding and long-time dumping intervals between each hauler. In order to increase the productivity of FC01 crushers and FC02 crushers it is necessary to re-engineer the hopper area so that it can receive greater feeding and improve the maneuver area to apply double dump technique. The next step was to re-engineer the hopper with the addition of wings to the FC01 crusher's hopper area and addition of stopper to the FC02 crusher's hopper so that a double dump technique can be used to increase the productivity of each crusher. The results of maneuver area improvement are the wider maneuvering dumping area in the FC01 and FC02. This stage costs Rp196.215.000,00 . The second stage which is the addition of wings on the left and right sides of the hopper and adding stopper in the FC02 hopper area costs Rp166.140.000,00 and the total of costs Rp362.355.000,00 . After the double dump method was applied to the FC01 and FC02 crushers, the FC01 crusher productivity increased to 500 tph and FC02 increased to 354 tph with a total revenue projection obtained at the end of 2018 of $36,672,864. Keyword : crusher, double dump, productivity, cost

Introduction: Palm creases have been studied for a long time and have been recently found to be helpful in tracking underlying medical and genetic conditions. Scientific study and typing of palm prints have been found to be lacking in the Nepalese population Methods: A cross sectional study was done on 252 subjects, 153 male and 99 females, from Kathmandu, Nepal. Subjects were selected by purposive sampling from different age groups. Demographic profile including age, sex, and handedness was collected. Palm print pattern was recorded by digital photography. Each photograph was analysed visually by single observer and pattern of palm crease was noted. Variation of each crease was also noted. Results: On the basis of relation between radial longitudinal crease and proximal transverse crease, 17.3% subjects had open type of palm crease which was significantly more in females while 76.6% subjects had closed type crease which was significantly more in males. Meeting type of palm crease was found in 5.7% of subjects. On the basis of relation between proximal and distal transverse crease, normal crease type was found in 90.1% of subjects, Simian type was found in 7.7% subjects and Sydney type was found in 1.4% of subjects. The concordance of this pattern in left and right palms was found statistically significant. Conclusions: This study presented data from 252 seemingly normal healthy subjects and found that most of them had the normal with no branching, that is normal 1 and closed crease types. Most of the individual major creases were seen to be branched type.

A very effective method to evaluate the products is the Customer Matrix (CM) that uses two coordinates: Perceived Used Value (PUV) and Perceived Price. Our researches extend this basic concept by adding the time variable, creating CM with different time horizons that assures a better understanding of competitive environment. In the first stage, the Customer Matrix is associated with a forecast method. The relevance tree method was used to predict the most probable evolution paths of electrodischarge machines. In the second stage, the CM with different time horizons is constructed, considering products evaluation for short, medium and long time. Finally, a strategy is conceived for an organization that attempts to ameliorate and consolidate its long term position against the main competitors, aiming at obtaining sustainable competitive advantage.

Insya Allah has been part of the Indonesian language and culture for a long time. However, there were very few linguistics studies on the use of Insya Allah. This study aimed to analyse the use of Insya Allah in the Indonesian context using the pragmatic approach. A total of 100 utterances spoken by various speakers at various situations were collected. The study focused on identifying the types of speech acts performed by Insya Allah using Searle’s speech act taxonomy (Searle, 1979). At the second stage, the pragmatic functions of Insya Allah were identified using a combination of classifications used by Pishghadam and Kermananshahi (2012), Nazzal (2005), Ibrahim, Shah, and Armia (2013), and Mohamed Ali (2014). The findings showed that Insya Allah was a reliable marker for commissive and expressive speech acts. This study also found two additional pragmatic functions of Insya Allah which have not been identified in previous studies.

The second stage of labor is one of the stages of labor that starts from the complete opening(10 cm) until the baby is born, and at primigravidas lasts 1 hour. Prolonged labor amounted to 5% of allcauses of maternal death. One of method to restrain the prolonged labor is to do zilgrei gymnastics. Thisstudy purposed to find the correlation of gymnastics zilgrei and long inpartu of second stage in primigravida.The design of this study was observational analytic with cross sectional approach. The populationin this study was inpartu primigravida maternity who do zilgrei gymnastics in January 2014–March 2015 in BPS Ny “S” Tunggulwulung village Malang with 40 respondents and the sample of 40respondents using total sampling techniques. The instrument used a data collection sheet from the bookdocumentation of labor BPS Ny “S”.The results showed Spearman correlation test at 5% error level andp value = 0.0001 <0.05. This means that Ho was rejected and Ha accepted and there was a significantcorrelation between zilgrei gymnastics with inpartu on second stage. The suggestion of this researchwas for health employee to socialize the implementation of zilgrei gymnastics as well as the benefits forthe labor, so that the second stage of labor does not take a long time.

The article deals with the history and prospects of the development of diplomatic relations between Mongolia and Russia. It is noted that diplomatic relations between the two states have a long history. The author identifies three main stages in the development of diplomatic relations between the two countries. The first stage was the Soviet one (until 1991). It was during this period that the foundations of cooperation between the two states were laid. At the same time, diplomatic relations were supported by broad cooperation in the economic and military-political spheres. Mongolia and Russia have been acting as allies for a long time. At the same time, the USSR acted as a guarantor of Mongolia's independence. The second stage (1991–2000) is characterized by the cooling of bilateral relations, which was due to the processes that took place in the USSR. The third stage (2000 and up to the present) is characterized by the intensification of diplomatic contacts. This is reflected in the frequency of official visits of the heads of state of Mongolia and Russia, as well as heads of diplomatic departments of Mongolia and Russia. The period of the 2000s. it is characterized by the presence of permanent diplomatic contacts between Mongolia and Russia. Their results are expressed in a number of declarations and agreements on cooperation between countries in various fields. Cross-border cooperation is also actively developing. The author notes that the prospects for further development of diplomatic relations between Mongolia and Russia are dictated by the goals of the foreign policy of both countries. The author notes that Mongolia is characterized by the desire to build equally equal relations with all states. Russia, on the contrary, seeks to build cooperation by attracting new member states to interstate associations of various directions. In particular, Russian diplomacy is making efforts to attract Mongolia to participate in the processes taking place within the framework of Eurasian integration. At the same time, the further development of cooperation is considered by the Russian side from the point of view of deepening the processes of Eurasian integration. At the same time, the Mongolian side, in accordance with the provisions of its foreign policy concept, does not seek to join any political associations. The author concludes that considering the prospects for further development of diplomatic relations between Mongolia and Russia, it is necessary to take into account the differences in approaches to the implementation of foreign policy between the two countries.

Core Production

The paper states an industrial engineering problem concerning industrial enterprises manufacturing goods for seasonal industries and activities. We developed a method for selecting optimum enterprise production capacity and forming a production plan that allows for meeting seasonal increases in demand, simultaneously ensuring rational utilisation of human resources, manufacturing equipment and storage facilities. The basis of the method is seeking the production volume function by minimising total expenditures for storage and manufacturing of goods, provided the seasonal demand is fully met over the whole period. We present a numerical implementation algorithm for our method and a calculation example. The main stages of the algorithm are as follows: setting the demand function; computing the core production capacity as dictated by steady equipment utilisation; varying the production plan until the minimum total expenditure condition is met. We ran a series of simulations that allowed us to establish the function describing the optimum production capacity as a fraction of the core capacity for various ratios of manufacturing expenditures to storage expenditures, and as a function of the overpayment rate for additional capacities
