Abstract
Increasing crop productivity can be done through improved cultivation technology by utilizing agricultural waste. This study aims to determine the development of late blight Phytophthora sp. and yields of potato crops through the application of trikokompos and rice husk biochar. Potato varieties used are Granola, perfect tillage 60 cm spacing between rows and 30 cm between seeds in one bed, beds covered with plastic mulch, fertilizing using NPK according to recommendations, weeding weeds according to conditions, controlling pests and diseases based on Integrated Pest Control. The difference in technological treatment studied was 1) trikokompos 10 tons/ha, 2) trikokompos 10 tons/ha + rice husk biochar 1 ton/ha, 3) trikokompos 10 tons/ha + rice husk biochar 2 tons/ha, and control (farmer technology without trikokompos and without rice husk biochar). The environmental design used was a Randomized Block Design (RBD) with 7 replications. Data were analyzed by The F test and further tests used with Duncan. Results showed that the intensity of late blight Phytophthora sp. was lower in potato plants that were treated with trikokompos and rice husk biochar. Application of trikokompos + rice husk biochar 2 tons/ha increased potato productivity to 27 tons/ha (28.6% higher than the control), and increasing the quality of potato tubers, especially XL tubers.

Abstract
Bandung and Jakarta have been connected by the Cipularang toll road since 2005. Based on data from Badan Pengatur Jalan Tol (BPJT), currently vehicle volume both in Bandung and Jakarta has grown rapidly. This is followed by an increasing volume of vehicles traveling from Jakarta to Bandung and vice versa. High Speed Train becoming one of the governments choice as a form of mass transportation modernization in Indonesia in building inter-city connectivity and regional development. In this study several scenarios for binary logistic regression analysis were conducted to analyze modal transfer from shuttle travel users to the Jakarta-Bandung High Speed Train. The probability of shuttle travel users who are willing to move using the Jakarta-Bandung High Speed Train is strongly influenced by variables, those are: Train Travel Time, Costs, Frequency and accessibility between modes. The probability of willingness to pay a ticket price of Rp 240,000 with a travel time of 60 minutes is 77.40%. The probability of willingness to pay a ticket price of Rp. 260,000 with a travel time of 50 minutes is 45.17%

Abstract
Technological developments not only changed the social order, but also penetrated the Sufistic region. Sufis, known as esoteric movements, cannot be separated from media devices, because the Sufi movement began to reveal its identity on social media without removing esoteric essence. The purpose of this article is to know and construct the spiritual space or Sufi movement in Indonesia which is mobilized through social media, as well as the involvement of the Sufi movement in providing social solutions. This paper is produced from a netnographic study of Sufi mysticism in social mesia. Leonard Swidler and Paul Mojzess theories about creed, code of behavior, cult and community-structure and Ahmad SyafiI Mufid about revitalizing urban sufism were used as analysis. The conclusions that can be taken are that there are certain contemporary Indonesian Sufism patterns on social media that provide opportunities for contemporary Sufism movements to give the concept of spirituality on social media

Abstract
The cavitation phenomena increase noise and vibration level in a centrifugal pump, which, if not properly maintain leads to catastrophic failure and total stop for the whole production process. It is important to develop a method that can detect cavitation as early as possible. Support vector machine (SVM) is one of pattern recognition techniques which requires statistical features as input for classifier modelling. However, the selection of statistical features is arbitrary, hence further investigation is needed. In this study ten statistical features are extracted from time domain vibration signal and selected using Relief Feature Selection. The vibration signal is taken from cavitation test-rig under four different pump conditions i.e., normal condition, early, medium and full cavitation. The selected features are used as input for two types of SVM, binary and multi class, to classify the new vibration data. Feature selection process reveals that variance, RMS, and SD are the best feature to use for SVM classification. The binary SVM method shows the best plot on early cavitation with accuracy 99% where Bayesian Optimization algorithm with multi class SVM is the best combination to classify all pump conditions with overall accuracy 100%.

Abstract
Bengawan Solo River is one of the longest natural channels in Indonesia which functioned as irrigation, fresh water supply and flood control. This river covers up to 1.6 million ha of area from the mountainous region in the Central of Java to the North Sea of Java with approximately 600 km of river reach length. Bengawan Solo River is an alluvial river indicated by Holocene formation along the river flow. Since alluvial soils were easy to transport, the river morphology changing becomes main problem. The river morphology changing causes local river channel alteration such as degradation, aggradation, river channel enlargement, and unequilibrium of river profile. In this study, the suspended sediment concentration (SSC), flow discharge (Q) and flow velocity (u) were investigated as primary data through field work. The SSC provides the maximum and minimum value with 1496.868 mg/l and 294.308 mg/l respectively correspond to the climate succession in Bengawan Solo River basin area. The suspended sediment value shows the promising sediment equilibrium correlation with the river profile transformation tendency. Inequality between input and output sediment concentration in this study explains the mechanism of river channel alteration including deposition and erosion processes.

Abstract
Calcita induced precipitation methods (CIPM) are the recently potential technique in geotechnical engineering to improve the engineering properties of sandy soil. One of the most promised methods is enzyme-mediated calcite precipitation (EMCP). In this technique, the mixed solution composed of reagents and an enzyme of urease, which produces calcite, is used as the grouting solution. The precipitated calcium carbonate in sandy soil provides bridges between the grains of sand, restricting their movement and, thus, leading to improving the strength and stiffness. This paper presents a review of the application of EMCP for soil improvement and discusses the additional material and their effect on the treatment process and engineering properties of the sandy soil. Envisioned application, potential advantages and the limitation of EMCP for soil stabilization are also presented and discussed. Finally, the primary challenges and the development opportunities for future research are briefly discussed.

Abstract
One of the emerging issue in the development of infrastructure is how to design and build new building that is more sustainable as well as retrofitting existing building towards resources saving. Improved design and appropriate intervention to the building may reduce its energy and water consumption and increase its ecological performance. This paper evaluates the design and performance of Bank Jateng Regional Branch Office in Jepara, Central Java in terms of its resources intensity. Edge building apps would be used to provide metrics-driven approach in the evaluation. As resources efficiency is considered in the building operation, then, the paper explores some of the scenario that works better to the building response to the local climate in reducing and saving resources consumption. The prediction of the identifying resources (energy) saving criteria were then evaluated. Environmental analysis tool then was employed to carry out in depth analysis of the building 3D model to some to the best scenarios and optimize the design. This ongoing research is expected to gain positive insight in improving building design in terms of its resources saving that in turn will be beneficial for the environment.

Abstract
In the reality of life, accounting management has many variables related to social aspects by identifying basic behavioral assumptions according to the Islamic world. The rule used in this approach is "maintaining good old things and taking new things better". Accounting management ideally must be built and practiced based on social values. Thus the information emitted is also social in nature. Ultimately, economic decisions taken by top management and managers are based on social values that encourage the creation of economic and business realities that lead to social piety who are prosperous and fair.

Abstract
One of the problems found is the lack of synergy between the social, emotional and spiritual attitudes with student-s knowledge and skills in following technological developments in the digital era. Thus, Islamic education must be prepared and should not be complacent in facing this era. This paper aims to explore the synergy between progressive values and social, emotional, spiritual values in Islamic education in order to face the challenges of the digital era. The synergy of those values is implemented in the goals, methods, material, educator qualification, and evaluation. This paper used library research using library materials sources and qualitative approach. The objective of progressive Islamic education must be able to create graduates who have scientific knowledge accompanied by social, emotional and spiritual values that are inherent in themselves. This goal can only be achieved if the learning system uses a model of integration between science and technology mastery and Islamic values in the selection of materials, methods, and evaluations. Meanwhile, the qualification of educators needed to realize the expected goals is derived from the model exemplified by the Prophet Muhammad which has four competencies namely, personal competence (sidiq), social competence (amanah), pedagogical competence (tabligh), and professional competence (fathanah)

Abstract
Hydroxyapatite (Ca10(PO4)6(OH)2: HAp) is widely used as biomaterials. Properties of Kulon Progo hydroxyapatite (KPHAp) derived from local materials Kulon Progo natural gypsum (KPNG) were investigated. Kulon Progo is the name of a district in Yogyakarta Indonesia. KPHAp powder was synthesized from KPNG with diammonium hydrogen phosphate [(NH4)2HPO4] via hydrothermal (microwave) method at 100oC for 30 minutes, then compacted and heated (sintering). The results of this study are as follows. The KPHAp has X-ray diffraction (XRD) and Fourier transforms infrared (FTIR) patterns are similar to HAp SRM 2910 and HAp 200. With increasing temperatures, density and diametral tensile strength (DTS) will increase. The sintering temperature at 1400oC presented the maximum value of density and DTS. The sintering temperature at 800oC and 1400oC presented the multiple phases of calcium phosphate. With increasing compaction value, density will increase, nevertheless DTS will decrease. The results of scanning electron microscopy (SEM) are also used for analyzing the microstructure of samples. From SEM indicated that the real sintering is at the temperature of 1400oC.

Abstract
Essential hypertension is the most popular catastrophic case in Indonesia that referred from primary health services to hospitals. High number of morbidity and mortality caused by hypertension increase financial burden of the state for catastrophic diseases. The current effort of our government to prevent and control hypertension is by health promotion through KIE. However, the facts that hypertension prevention keep developing thus this would be a continuous global challenge for the professionals of health services. This is the reason why its important to investigate interventions that could increase control the blood pressure. The aim of this systematic review is to gain best literatures about health education about the prevention of hypertension based on community that have potential strength to regenerate clinical practice recommendations to improve preventive and promotive efforts for hypertension. Method of this literature review was using systematic searching of electronic databases from Google and Pubmed by following keywords : hypertension intervention strategies + journal, community based hypertension control programs that work + journal, hypertension AND community based health education, hypertension AND community-based nutrition DASH, hypertension AND community based control programs. Inclusion criterias of the study focused on community based education interventions for hypertension and has complete explanation about it whilst exclusion criteria of the study was all articles that older than the latest 10 years. 10 journals based on those criterias above chosen to proceed. Results of the study shows that all researches were done in developed countries and most of the articles were using quantitative methods. Community based health education for people with hypertension is an effort to help hypertension control programs. There are 4 (four) health interventions related to community based hypertension education program which are mass media campaign to reduce salt consumption, workshop programs through social volunteering or health activists, hypertension group education about dash and lifestyle then comprehensive hypertension prevention and promotive programs.

Abstract
This article focuses on a teacher identity shift in the Javanese community in nowadays digital era. Teachers in a traditional situation are those with an honorable position because of being the reference and role model for their community. In addition, the teacher is also considered as responsible for all students behaviors both in and outside the classroom. However, those teachers identities seem to have shifted due to the occurrence of socio-anthropological alteration in society. Despite these changes, they remain pivotal in terms of values learning transformation. Such a task has genuinely become their professional responsibilities. The qualitative approach in this study is to deeply investigate how the reconstruction of the teacher identity is carried out in the modern Javanese society. The findings show that in the context of Javanese peoples lives, socio-anthropological conditions have an effect to the shifting of the meaning of teachers. Teachers have been considered as only ordinary professions. It may happen because in the recent massive digital knowledge transformation, any information has been easily searched for and obtained. Consequently, the position of teachers has no longer been regarded as the only source of knowledge. Therefore, teachers need to revitalize their identities in the context of globally digital knowledge.

Abstract
Teacher professional Development is crucial because the success of the students are closely related with the teacher competence to achieve the goals of education. Therefore it is a must for the teacher to always learn throughout their career, and one of the learnings is by teacher learning from teacher or peer observation. The advantage of the peer observation is as the mean to reflect the practice of teaching which in turn will give input to their partner to improve the competence in the teaching learning process. The trust and respect among teachers who is observed and become the observer will determine the effectiveness of the process. Conducting the process of peer observation need commitment from parties involved in the teaching learning process. For the institutions, the process means the human resources and budget allocation to build the system, and as the continuing process, there must be efforts to maintain its running. On the other hand, the teachers are reluctant to be observed because they will feel insecure since no body like to be criticized, fear to change the routine, and by doing the peer observation process means more works for the teachers. Those reasons are the problems arise in conducting peer observation. This research is intended to answer the following questions below. (1) How do teachers perceive and engage in the practice of peer observation at the Language Training Center? and (2) How is the implementation of the peer observation at the Language Center? The research design for this study is the qualitative case study. The choice of this research design is characterized by case study that is an in-depth analysis with a specific and complex phenomenon in a bounded system that could be limited by time and place. The research site is the Language Center of a private university in Indonesia. Purposeful sampling is used to determine the participants. The selection will be based on the length of employment (minimum one year), has already involved in the peer observation process at least one cycle or phase, is active teaching and do the peer observation process in the intended semester when the research is conducted. The other participants of the research were the decision makers in this institution. The answer of those two questions will be divided into four findings. They are: (1) The institution aims in conducting the Peer Observation activities, (2) The teacher perception on the implementation of the research, (3) The implementation of the Peer Observation and (4) the feedback for the next implementation.

Abstract
Instilling the 21st century skills (communication, collaboration, critical thinking, and creativity) in EFL classrooms as an attempt to equip the students to compete in the global era can be demanding. As a foreign language, teaching English for Indonesian students itself may carry its own issues requiring teachers to deal with. Moreover, teachers have greater challenges to select appropriate teaching strategies incorporating the required language and the 4 Cs skills. This study aims to investigate teaching strategies implemented in Indonesian EFL classroom setting to facilitate the aforementioned skills. This study is descriptive qualitative. There will be 6 teachers of a language training center of a private university in Yogyakarta selected as the participants. Interviews will be conducted to gather the data needed. It is expected that the findings of this study can serve as a reference in applying strategies in teaching English as a foreign language to facilitate the 4 Cs skills necessary for the EFL Indonesian learners to compete in the global market era.

Abstract
In the flood management, one way to reduce the volume of flood is by using polder system. This system is implemented by The Government of DKI Jakarta Province with retention ponds in some area. To keep its function, some routine maintenance with appropriate budget of each polder are running, but there are some conditions which give impact to the polder functions and services. There are many aspects that contributed in the decreasing of polder service capability. In other hand, Water Resources Agency of DKI Jakarta Province, who is responsible for the maintenance of those polders, does not have any guideline to evaluate the polder service and correlate it with appropriate maintenance budget. This research analyzed seven selected polders in DKI Jakarta with 41 various variables and indicators that used to evaluate polder services, which are 4 technical variables (Tx) with 17 indicators (tx) and 5 non-technical variables (NTx) with 15 indicators (ntx). As the result of this research, evaluating the polder services are more precisely by using 36 various variables and indicators, which are 4 technical variables with 15 indicators and 5 non-technical variables with 12 indicators.

Abstract
ABSTRACT:This research analyzes various techniques applied in simultaneous interpretation mode on the Regional Meeting of La Via Campesina Conference. The research is focused on the interpreting process in two languages from English into Bahasa and vice-versa. The analysis is aimed to identify the techniques applied in simultaneous interpreting and the factors that influenced the technique applied during interpreting process. This research is descriptive qualitative research. The research result showed that the majority techniques used by simultaneous interpreter are summarizing, reformulation, omission, transcoding, and simplification. The factors impeded summarizing techniques are, speed and time lag, speech directionality, and memory. The factors impeded reformulation techniques are, processing director, accent and dialect, and fast speech delivery. The factors impeded simplification techniques are, number, speech density, and high profile attendees. The factors impeded omission techniques are, memory and attention, visibility, noise and technical difficulties. The factors impeded transcoding techniques are, prior information, syntax, and bilingualism. The findings further indicate that due to different language system the simultaneous interpreter should be more aware of the interpreting techniques. In order to be able to translate what was said within the time allowed by the speakers pace without changing the natural flow of the speaker-s speech.

Abstract
Broccoli (Brassica oleraceae) is one of the prospective agricultural products to be developed in Indonesia because it is a source of vitamin A, B complex, C, ascorbic acid, thiamin, riboflavin, calcium, iron and minerals essential for the fulfillment of human nutrition and contains sulforaphane which can prevent cancer, besides it helps digestion, neutralizes acid and does not contain cholesterol. The amount of vitamin content found in broccoli makes the demand for broccoli on the market has increased by 15-20% per year. However, the high demand is not balanced with adequate quality and quantity of production. One of the causes of decreasing the quality and quantity of broccoli production is the use of inorganic fertilizers continuously. Provision of inorganic fertilizers or chemical fertilizers for a long time can cause soil damage in physics, biology, and chemistry. Plant organic waste is the raw material for the fermentation process for soil microbes which is useful for increasing the quantity and quality of crop production and maintaining environmental sustainability. Organic waste that has undergone a fermentation process can be used by plants as liquid organic fertilizer and at the same time can be used by plants as a stimulant to grow. The aim of the study was to examine the relationship between the dose and concentration of fruit organic waste extract to growth and yield of broccoli. The study was carried out on the integrated land of the Faculty of Agriculture-Animal Husbandry of the University of Muhammadiyah Malang from February to May 2018. It is a factorial experiment arranged in a Randomized Block Design and repeated 4 times. The first factor is the concentration of fruit organic waste extract, namely K1: 50 cc /l ; K2: 100 cc /l; K3: 150 cc /l, the second factor is the dosage of fruit organic waste extract, namely: D1: 50 ml /plant; D2: 100 ml /plant. The parameters of observation included plant height, number of leaves, stem diameter, flower diameter, flower weight, wet weight, dry weight. Data were analyzed using Fishers test, then tested using BNJ test 5%. The results showed no interaction between the concentration and dosage of fruit organic waste extract on the growth and production of broccoli plants. There is a positive correlation between each observed variable. The best concentration of fruit organic waste extract is 100 cc/l. The best dose of fruit organic waste extract is 50 ml /plant

Abstract
Dhikrullah, in the Koran mentioned as one of the main commands to Muslims, but the study of mentioning the name of Allah scientifically in order to find out what phenomena occur in humans when doing dhikrullah until now has not been maximized. This study is an academic response to the phenomenon of dhikrullah which has emerged frequently among Muslims lately. This study used qualitative data from 4 informants to find the dhikrullah model and quantitative data from 10 subjects were obtained through Electro Encephalo Graf to see the effects of dhikrullah on brain waves. The results show that there is a relationship between the scalp hygiane with brain waves. Special room dim light affect brain waves. Tense skin affects brain waves. Doing hyperventilation as in dhikrullah helps to detect disturbances in the brain. Closing eyes during dhikrullah produce alpha waves in the brain. Dhikrullah by moving the tongue can be recorded by using EEG. Therefore, the authors conclude that this study is a new approach to see the phenomenon of dhikrullah. The United Nations, especially WHO can use the phenomenon of dhikrullah as a new approach to help people who need a solution from a permanent spiritual approach.

Abstract
There are some procedures to advance the quality of papaya; one of which is by sufficing the need of high-quality seeds in proper amount. Using plastic polybag for plant nursery will negatively pollute the environment and is polybagential for resisting the root-s growth. Therefore, organic polybag is claimed as the best solution due to its excellence of not undergoing segregation process during seed plantation. In addition, it also has good drainage and aeration to support the root-s growth. Further, this current research aimed at testing the use of organic polybag for papaya nursery. There were 7 treatments in total with organic polybag as the main highlight. The control variable was organic polybag (PO – with 60% of water hyacinth: 40% banana pseudo stem). Meanwhile, the 7 treatments comprised 59% of water hyacinth: 40% banana pseudo stem: 1% manure [POA – organic polybag with chicken manure; POS – organic polybag with cow manure; POK – organic polybag with goat manure); and POP – organic polybag with manure made of Tithonia diversifolia] and 59% of water hyacinth: 39% banana pseudo stem: 2% combined manure [POAS (chicken + cow manures), POAK (chicken + goat manures), POAP (chicken + Tithonia diversifolia manures)]. The variables under observation consisted of height of plant (cm), number of leaves (blade), diameter of stem (mm), length of root-s penetration (day), dry weight of stem (g), and weight of root (gr). Moreover, the data were analyzed by using F-test, followed by BNJ or Tukey appealing test with 5% of significance and finished by correlational analysis in between variables of observation. The use of organic polybag for papaya nursery resulted in significant effect when it was compared to the control on variables of observation (such as number of leaves, length of root, dry weight of root, and diameter of stem); yet, it was relatively different compared to that of in POP treatment on height variable (from 21 to 28 days after planting), in POA treatment, and in POAK treatment on stem-s diameter variable.

Abstract
Indonesian text preprocessing is still very limited and requires tools that can help Indonesian researchers to conduct research in the field of text mining in Indonesian, especially on Twitter. Preprocessing needed for text mining processes such as deleting @ notation; Http; stop words; normalize acronym words, slang words, emoticons; and Indonesian stemming. Gataframework besides providing an OPP-based PHP framework, it also provides text mining preprocessing tools to support those needs. The results of Gataframework text mining preprocessing output can be combined with other tools, one of which is Rapidminer. Gataframework also features a web services API that can be connected with other applications. Since 2018, many studies related to Text Mining have begun to use Gataframework as an alternative tool in the preprocessing stage. The results of the use or quality of this tool are assessed by the Likert evaluation model and the Functionality, Usability, Reliability, Performance, Supportability (FURPS) is known as a model for classifying method which has the parameters Functionality, Usability, Reality, Performance, and Supportability. Based on Gataframework users assessment of 21 respondents, the results were Functionality (87.62%), Usability (85.71%), Reality (85.71%), Performance (80.95%), and Supportability (85.71%) while the average value of the overall parameters was 85.14 %, which means very good.
