Abstract
Increased population growth will impact on changes in land use for human settlements and other living needs. It is caused to land use change that negatively impacts the environment if it is not managed properly. Therefore, the information regarding to land use map is essentially needed. This research aims to asses land use change in Bedadung Jember watershed using a remote sensing technology as Bedadung watershed is one of the largest watersheds through the settlement areas of Jember regency. Remote sensing technology is widely used to provide any information such as land use changes without having an immediate monitoring in site. Therefore, it can be used to monitor land use changes in an area regularly. Landsat-8 has 30x30 m resolution is one of remote sensing technologies which is suitable for this research. The method of classifying land use change used supervised classification with Normalized Difference Vegetation Index (NDVI) analysis approach in Geographic Information System (GIS). The results showed that within 16 years from 2001-2017, Bedadung Jember watershed had increased its settlement areas to 36,79 km2 or 2,66%, forest areas are decreased to 47,98 km2 or 3,47%, paddy field areas are decreased to 122,33 km2 or 8,84%, open areas are increased to 3,86 km2 or 0,28%, shrub areas are increased to 37,68 km2 or 2,72% and plantation areas are increased to 90,82 km2 or 6,57%. Simulation results with daily rainfall plans on land use in 2001 and 2017 show that the peak discharge generated in 2001 was 68.8 m3/s, while in 2017, it was 103.9 m3/s. Peak discharge in 2017 is higher than in 2001. This simulation shows that the condition of land use in 2001 is better than in 2017.

Abstract
The research was based on the application of the curriculum condition and learning in the school of early childhood education. Psychic development, appropriate early childhood does not yet have enough readiness to receive learn to read. Students are not yet mature enough to accept the burden of the material symbols of that language. However, from previous research conducted, it found that 98% of the school taught reading for their students. It is done by a variety of reasons — for example, the demands of the parents/guardians of students, school level demands of the next, commercial purposes, and so on. On the other hand, the students were during the golden age to absorb a variety of information that can be relied upon for readiness and maturity of learning was going to do later on. Based on the research results that are relevant to this study, it was found that children who have a parent with optimizing the opportunity receive language stimulation well will grow into adults who are capable in terms of linguistic and have a tendency to more easily understand the readings five times greater than adults who in his childhood did not receive similar stimuli. The research of applying research methods combined concerning the development model Akker consists of four steps of analysis. At this stage of the development of the early models used two students who have in common the maturity to learn from three schools with different economic and social conditions for the trial subject or the respondent. Then proceeded on a limited testing phase is done with 30 students from five different schools. Extensive test phase carried out in the application of the 40 students from ten different schools. Rating (sig) is less than 0.05 (α), then Ho is rejected. This means that there is a difference of values on the Group 1 (Pre-order) and group 2 (Post). If seen from the average, then the average group 2 (post) = 77.9410 is higher than the average Group 1 (pre) = 59.7450. Then the values of Group 2 (position) better than group 1 (pre). As a result, an increase in the number of students from grades pre to post.

Published: June 2020

Abstract
The increase in population and motor vehicles fueled by oil (BBM) resulted in increased Greenhouse Gas Emissions (GHG), especially Carbon gas emissions. Besides the increase in gas is also derived from household waste. The amount of carbon emissions in an area depends on the number of vehicles operating such as main roads, residential ro ads, roads that are planted with green plants and terminals. One that can reduce carbon dioxide gas is greening, by planting plants that can absorb a lot of carbon emissions. Greening can be done by planting green plants or vegetation on highways and housing. The existence of Green Open Space (RTH) will result in the assimilation of carbon by vegetation which will reduce the concentration of CO2 in the atmosphere. The research objective is to measure the concentration of carbon emissions from motor vehicles, modeling the relationship between carbon emissions and the number of motor vehicles and knowing the need for green space in Jember Regency for CO2 absorption for 5 years. Research by field survey, primary and secondary data by calculating the type and number of vehicles that pass, as well as green space in the City of Jember. The results show carbon dioxide emissions in the Penjaitan Road for four days amounting to 3450.6 kg / year or 2875.5 kg / year / km. The required green open space on Panjaitan road is 0.006 Ha / year or 0.005 Ha / year / km. Cassia Plant 0.54 Trees / km, or Cananga plant 3.8 Trees / km.

Published: June 2020

Abstract
In this paper, structural characteristics of the forward fuselage of an aircraft were analyzed. Loadbearing characteristics of longitudinal members and transverse members of the forward fuselage were summarized. After analysis, longitudinal members were identified as main factors that affected structural deformation. Then, finite element analysis and sensitivity analysis methods were combined to determine accurate stiffness sensitivity parameters of the forward fuselage structure. Through analysis of the displacement sensitivity curve, the law of changes in stiffness of the forward fuselage with changes in sizes of longitudinal members was found out. Design requirements on stiffness of the forward fuselage were well satisfied by controlling parameters on purpose. Then, some experiments were designed to compare calculated displacements of the forward fuselage. Experiment results proved the accuracy of the proposed analysis method, allowing designers to get rid of their experience-based the forward fuselage stiffness design methods and providing a theoretical basis for the forward fuselage stiffness design. The proposed method could also provide some reference for structural design of new or retrofitted planes.

Abstract
Lumban Bulbul Beach, located on the bank of Lake Toba, the North part of Balige City has transformed rapidly in the last 5 years from qualitative to quantitative values. The space of village for daily life with the use-value of living focused on family and agriculture and livestock, today has become commercial activities space with exchanged value. The government of Toba Samosir District intervenes the beach construction to show the progress of development. For decades, community planted bamboo along the beach as wind defenses and maintains fish life and farming, but today transformed into the recreational beach with food and beverages stalls of the community. The local wisdom is ignored and exploited for commercial purposes. The orientations of the houses gradually turn towards the beach for serving modern recreational life. The dualism of life occurs in the area is creating ambiguity, one side as the local community’s daily life, and the other side to gain profit. The research conducted by quantitative method with the observation of space, activity, users, find the ambiguity of the house along the beach, between daily life space with use-value of the community for several generations, and modern commercial space along the beach with exchange-value.

Abstract
Biodiesel is renewable energy that can be renewed, biodegradable and enviromentally friendly. Transesterification is a reaction which is used to produce biodiesel where this reaction uses catalyst which was made from blood cockle shell ash which has been combusted at the temperature of 850°C for 3 hours and the amount of the ash being used was 8%, 10% and 12% (m/m). The ash used was dissolved into methanol with the mole ratio of methanol to oil of 9:1, 12:1 (n/n) to obtain calcium methoxide. Used oil was filtered then esterificated by 3% of catalyst (m/m), H2SO4 98% and methanol:oil TG (6:1) to reduce the FFA until it is less than 1%. Transesterification was done at the reaction temperature of 65°C for 3 hours and constantly stirred at the speed of 700 rpm. Quantitatively, optimum biodiesel yield obtained was 56.51% at the condition of 12% (m/m) of blood cockle ash, 12:1 mole ratio of methanol to used oil. The specification of the biodiesel such as density, kinematic viscosity and flash point at this condition matched the standard of biodiesel SNI 04-7182-2006 and according to gas chromatography analysis, the purity of the biodiesel produced is 98.79%.

Abstract
Tofu liquid waste contains a high organic load so that the processing system is needed to reduce the pollutant parameters in the wastewater to fulfill the quality standards. The most suitable treatment for organic loads is anaerobic processing. One anaerobic processing system uses the Hybrid Upflow Anaerob Sludge Blanket (HUASB) reactor with the consideration that this reactor has the advantage of maintaining high amounts of biomass concentrations, high load rates for operation, good deposition capability, and good solid-liquid separation due to appropriate granulation. The purpose of this study was to determine the effect of adding trace metal FeCl3 to the removal of COD, TSS and biogas production on tofu wastewater treatment at the HUASB reactor. The process of tofu wastewater treatment with the addition of trace metal in the HUASB reactor using a batch circulation system with a reactor volume of 9 liters. The reactor is operated by variations in the concentration of tofu wastewater (75 and 100%) and trace metal concentrations (0.3-0.6 mg / L). The parameters observed in this study were pH, COD, TSS, and biogas produced. The results showed that the optimum biogas production of 8.190 mL at the concentration of tofu wastewater was 75% with the concentration of trace metal 0.6 mg/L and allowance for COD and TSS of 94.09% and 94.02%.
