Analisis Pengaruh Beban Lalu Lintas Terhadap Tingkat Kerusakan Jalan Soenandar Priyo Sudarmo, Kecamatan Prambon, Kabupaten Sidoarjo
Full text linkSoenandar Priyo Sudarmo Road often experiences significant stress due to
high traffic volume and load, particularly from heavy vehicles used for various
industrial activities in Prambon District. Additionally, during the survey, various types
of damage were identified, such as pothole, alligator cracking, and raveling. Based on
this, the author conducted a study to analyze the impact of traffic load on the level of
damage to Soenandar Priyo Sudarmo Road. The primary data used included road
damage data, riding quality, and traffic counting, while the secondary data included
road geometric data and Average Daily Traffic. This study used the Indrasurya and
Dirgolaksono (1990) method to analyze road damage, as this method is an adaptation
of various previous road damage evaluation methods, taking into account road
conditions in Indonesia The effect of traffic load on road damage was analyzed using
exponential regression to identify the non-linear relationship between the independent
variable and the dependent variable. The analysis results showed that the types of road
damage found were quite diverse, including potholes, raveling, alligator cracking,
distortion, transverse and longitudinal cracks, rutting, patching, and edge
deterioration. Based on the analysis per segment, the average damage value per
segment ranged from 18.85% to 45.16%, with riding quality in the RQ 1 to RQ 3
categories. Regression showed that heavy vehicles, particularly ESAL 1.2–22 trailers,
had the most significant impact on road damage with an R² value of 0.905. This study
indicates that traffic load, particularly from heavy vehicles, significantly contributes
to road damage. Based on these results, recommended road maintenance is
categorized into light, moderate, and no maintenance, depending on the condition of
each segment
Sifat Fisik, Sifat Kimia, Jumlah Sel Somatik dan Kualitas Mikrobiologis Susu Kambing Kaligesing di Cordero Farm
No full textProducers and consumers are both becoming increasingly interested in goat’s milk. Consumers are attracted by its high digestibility, low allergenicity and beneficial chemical composition, more similar to human than to cow’s milk. Producers are attracted by the hope of easier access to the market of goat than of cow’s milk, production of the latter being restricted by low productivity, as well as by the possibility of making luxury products sold at increased prices. Popular dairy goat inIndonesia is Ettawa Grade (PE), one of popular strain is Kaligesing. Research on goat milk quality in Indonesia especially Kaligesing goat milk is very limited. This research important for consideration in the preparation of goat milk quality standards in Indonesia. Lactation Kaligesing does were selected from herd in Cordero Farm to determine variations of milk somatic cell counts (SCC), physco-chemical properties and microbiological quality. Individual milk samples were collected daily from morning and evening milking. Milk samples were analyzed for SCC using a breed method and for physco-chemical characteristics using milk analyzer. The conventional bacteriological method for bacterial isolation and the indirect test (IPB-1 Test) for determining udder inflammation status were employed. Daily milk production increased after parturition (1-2 weeks in lactation) and then decreased gradually as lactation advanced.Goats reached their peak milk production (2.07±0.63 L/doe per day) in approximately 2 weeks after parturition. Milk from the herd had high fat, SNF and protein contents and it can be classified as premium quality. Fat, SNF, protein, lactose, density and freezing point of Kaligesing goat relatively constant from 2 weeks of lactation to the end of lactation. IPB-1 test reaction did not effect physco-chemical properties of goat milk (P>0.05), except for pH (IPB-1 test reaction Normal higher than IPB-1 test reaction +3). Over all, 36.36% of milk samples contained more than 1.0 x l06 SCC ml-1, the legal limit for Grade A goat milk or classified as standard quality. As much as 50.65% milk samples classified as premium quality which contained less than 7.0 x 105 SCC ml-1 and 12.99% of milk samples classified as good quality which contained 7.0 x 105-1.0 x 106 SCC ml-1. Milk samples which had IPB-1 reaction +2 and +3 exceeded the maximum limit of total plate count (TPC) and Staphylococcus aureus. Milk samples which had IPB-1 reaction neutral, trace and +1 on mastitis test can be classified as premium quality with TPC <5.0 x104 ml-1. Total number of coliform bacteria for milk samples, except for samples with mastitis which had IPB-1 reaction +3 on mastitis test did not exceed 103 ml-1, maximum limit of coliform contamination
Konflik Batin Tokoh Utama dalam Novel Alisya Karya Muhammad Makhdlori Kajian Psikologi Sastra
Full text linkWibowo, Bayu Priyo. 2017, "The Inner Conflict of the Primary Figure in Alisya's Novel The work of Muhammad Makhdlori is a literary psychology study". Thesis, Indonesian Literature Study Program, Undergraduate Program, Faculty of Humanities, Diponegoro University, Semarang.
Novel Alisya The work of Muhammad Makhdlori recounts the inner conflict of the main character Alisya against herself and her environment. This novel discusses the reality of human life is closely related to the problems of life that affects the development of psychology. The purpose of this study is to describe the intrinsic elements that exist in Alisya's novel and reveal the personality of Alisya as the main character. The author uses a fictional structure to describe the element of the novel builder (figure and characterization, plot, and background). The author also uses the theory of literary psychology that focuses on psychoanalysis Sigmund Freud to examine the personality of the main character through the structure of personality id, ego and superego.
The result of structural analysis of Alisya's novel contains eleven figures consisting of one main character and ten additional characters; The plot of Alisya's novel is an advanced path; The setting contained in this novel is the setting of time, place, and social.
The result of the analysis of personality structure in outline of Alisya figure has no balance between Id, Ego and Superego. Alisya's id and ego are so prominent that she is incapable of controlling her attitude and behavior. Although initially the more dominant Alisya character shows the aspect id and ego, but superego aspects of the morality of her personality can make Alisya back to the right way.

No full textAbstrakIslam is a religion that loves brotherhood. Islam teaches good cooperation between humans in the fields of muamalah and transactions. One form of transaction in trading is buying and selling. A person who will build a house will surely he will plan in advance before building his house, either by saving first or collecting building materials needed little by little. There are those who are looking for alternatives in building permanent houses, that is by buying building materials in stages, the buyer will store the building materials that he has bought at a building store. Buyers and shopkeepers enter into a custody agreement. The problem that then arises is if the store uses the stored goods to be sold again to other buyers, even though the store is able to bear the risks that may arise. These problems will be linked in the application of the principle of wadi'ah to the MUI DSN fatwa number 02 / DSN-MUI / IV / 2000 on building materials safekeeping services.This research is analytical descriptive by describing the conditions found in the field and analyzing them to get conclusions. With empirical legal research, the author examines the implementation of the wadi'ah contract on safekeeping of building materials associated with the MUI Fatwa DSN. Descriptive qualitative analysis is used to analyze the reality of the implementation of the wadi'ah contract on safekeeping building materials.The practice of storing building materials in Sumber Urip Surabaya's building stores has fulfilled the terms and conditions of the yaddhamanah wadi'ah contract, where the buyer acts as the entrusted person, while the building store acts as the person who receives the item deposited. The deposit is in the form of cement. It is said yaddhamanah because the building store uses cement from the buyer's savings by selling the cement to other buyers without notifying the buyer when the contract occurs. Keywords: Implementation, Wadi’ah, Safekeepin

=========================================================
Hydropower from rivers or marine currents, tides and irrigation canal is one of the best renewable sources. The energy of water flow is a natural resource that can be obtained free of charge and is available continuously throughout the year, and environmentally friendly. As an archipelagic country, Indonesia has the potential for high water energy development. The potential for river currents with an average depth of 2 (two) meters in Indonesian waters ranges from 0.12 - 0.32 m/s. For this low water flow rate, the Savonius type water turbine is most suitable.
The low performance of the Savonius turbine compared to other types of turbines has inspired this research to make improvements to its performance. This study aims to improve the performance of the Savonius water turbine, which means an increase in the positive torque of the turbine. The increase in the positive torque of the turbine is done by placing a circular cylinder in front of or beside the advancing blade to increase the drag force on the advancing blade, or in front of the returning blade to reduce the force on the blade.This research uses numerical and experimental methods. The numerical method used is intended to visualize flow phenomena that cannot be determined
experimentally. The numerical results are verified and validated by published experimental data. Numerical modelling using Reynolds Averaged Navier - Stokes
(RANS) with descriptive second-order upwind and Realizable k-epsilon (RKE)turbulence model was carried out to investigate the effect of the cylinder on the torque and power of the Savonius turbine. The experiment was carried out on an flowing tank with a water height of 900 mm and a channel width of 1100 mm. Savonius turbine blade diameter measuring 400 mm. The speed of the water flow is adjusted according to the capability of the equipment of velocity measurement of 0.22 m/s. The important parameters in this study are the diameter of the circular cylinder (ds) and the distance between circular cylinder and advancing blade (X) calculated relative to the turbine diameter are (ds/D) and (X/D), respectively, and also the angle of the stagger () in front of the advancing blade and the angle of the
stagger (α) in front of the returning blade. The Circular cylinder installation is performed in front and beside of the advancing blade, and in front of the returning
blade.
The numerical results show that the placement of a circular cylinder measuring ds = 0.7 D on the side of the advancing blade gives the highest increase in the power coefficient of the turbine, which is 25.10% at TSR = 0.7. The placement of the cylinder on the side of the advancing blade at a horizontal distance of x = 0.5D gives the highest performance increase, which is 17.31% at TSR = 0.9.
The placement of circular cylinder in the stagger variation in front of the advancing blade shows that the best power coefficient of turbine occurs at a stagger angle of 60o with an increase in the power coefficient of about 15.82% at TSR = 0.9. Meanwhile, the placement of circular cylinders on the stagger variation in front of the returning blade shows the best performance on the 60o stagger with an increase in power coefficient of about 11.74% at TSR 0.9. Furthermore, the comparison between the experimental and numerical results shows the agreement of each other

STUDI NUMERIK PENGARUH VARIASI PANJANG DEFLEKTOR DI DEPAN RETURNING BLADE TERHADAP PERFORMA TURBIN ANGIN SAVONIUS MYRING n=1
No full textThe experiment on the Savonius wind turbine with Myring n=1, by adding a deflector in front of the returning blade, has been proven to improve its performance. However, one limitation of the experiment was the inability to visualize the airflow, such as velocity contours, streamline velocity, and pressure contours. Therefore, this study was conducted to provide a visualization of the airflow. This research uses a numerical analysis method with the aid of computational fluid dynamics (CFD)-based software in a 3D model. The study employs a Savonius wind turbine model with Myring n=1, having a diameter and height of 40 cm. The variations in deflector length used are 10 cm, 20 cm, 30 cm, and 40 cm. The simulation results showed a performance improvement of 17,8% compared to the Savonius wind turbine with Myring n=1 without a deflector, with the highest coefficient of power value occurring at a TSR of 0,8, reaching a value of 0,24
Analisa Pengaruh Sudut Stagger Di Depan Advancing Blade Terhadap Performa Turbin Air Savonius Myring Blade n=1 & n=2
Full text linkSavonius water turbines can work at low fluid flow rates and have high torque, but have disadvantageswhich is the lowest Cp value compared to other turbine types. Efficiency can be improved by changing the shapeof the Savonius Turbine blade using the myring equation and adding an obstacle. The experimental method in thisstudy combines two blades resulting from variations of the value (n) in the myring equation n = 1 and n = 2, withmyring n = 1 placed on the concave side and n = 2 on the convex side. To improve performance, a 12 cm diametercircular cylinder is placed in front of the advancing blade with varying stagger angles. The test model has a heightof 0.40 m and a diameter of 0.40 m which will be tested in a flowing tank with a width of 1 m and height of 1 m.Experiments were carried out at a current speed of 0.2 m / s by measuring the turbine rotation and load to producea torque coefficient and a power coefficient. The experimental results show that the placement of the circularcylinder with ds / D = 0.3, S / D = 0.75, and ? = 60º obtained the highest performance with an angular velocityof 0.5160 rad / s, Coefficient of torque (Ct) of 0.2936 and Coefficient of power (Cp) of 0.1515. With a percentageincrease compared to myring n = 1 and n = 2 without an obstacle of 10.27%, this proves that the addition of acircular cylinder can improve the performance of Savonius water turbines
