Abstract
There has been more than one the solving process of the problem sometimes. It has been named an open-ended context when related to an approach, and in this study purposed to use a geometric-function problem for analyzing each process that was experienced a student when they were conceptualizing the completion. Three students purposively who was a sample is registered by the senior high school in a science program at the region of West Jakarta, Indonesia. Student solved the problem in this explorative study, there were two choices of completion ways actually, technical or conceptual, but they used the procedural technique operational. Two conceptualizing process in solving the problem, it was constructing the algebraic representation of the function and organizing concepts. But, there is only one between the other where was effective and efficient of the process based on the perspective of the management theory. The first process was efficient by recognizing the function in algebraic and graphic representation. But, the second process affected the solution ineffective because all three students have been miss controlling the domain function concept even though it is a resource. So, an effective and efficient for learning is when students involving more conceptual knowledge.

Abstract
The high competition in the globalization era makes students often faced with various complicated problems. To be able to face increasingly challenging problems it is necessary to have habits of mind and strong understanding. Habits of mind and understanding can be formed and trained by applying formative assessments. The problem is not all the formative assessment strategies that students receive in lectures are in line as needed. In this research we will apply formative assessment through the stages of UbD, which aims to shape the habits of mind and understanding of the students. In contrast to other studies, this research used inverse design that is understanding by design in choosing the formative assessment strategy used. The method used is quantitative method with one-group pre-test post-test design. The purpose of this research is to know the improvement of habits of mind and understanding of the students. The result of the research shows that there is a significant increase both in students habits of mind and students understanding. The students habits of mind increases at medium category (N-gain = 43,9%), while students- understanding increases at medium category (N-gain = 45% ).

Abstract
The purpose of the work is to provide an overview of relevant studies that portray the active role that rural communities in Sulawesi have played in generating knowledge based on a practiced understanding of their environment. For long periods of time local peoples have depended on their own environments for the provision of a variety of resources, and somehow have developed certain ways in conserving biodiversity. Through a long history of observations and resource-use practices local people then often possess a broad knowledge that has accumulated through generation to generation. This can be of great value and complement the scientific knowledge we have today. They are naturally aware that “biological diversity” is a crucial in generating the ecological services and natural resources on which they depend. Their practices for the conservation of biodiversity were obtained through trial and error processes over a long historical time period. Conserving this knowledge would be most appropriately accomplished through promoting the community-based resource-management systems of local peoples. Results show that their knowledge base is indefinite and their implementation involves an intimate relationship with the belief system that conservation of biodiversity is fully recognized if ecosystems and biodiversity are to be managed sustainably.

Abstract This research was a stem-based didactic research which was conducted on sixth grade students. This didactic design was arranged in mathematics learning by using mathematic skills on the concept of integer count operations, comparisons, and measurements. While using the simple aircraft on science subject. Stem (science, technology, engineering, and mathematics) was used in didactic design to create a didactic situation that aimed students to build a simple plane where the students used their mathematic skills. The goal of this research was to improve 21st century skills, including; critical thinking, creative thinking, problem solving, communicating and network building. Didactic design was a learning program that contained a didactic situation, hyphotetical learning trajectory, students response, and anticipation of students response. This research was conducted on three didactic designs. In the first design, students planed problem solving by designing a simple tool based on provided materials, the needs and the lowest price. In this process students used the concept of integer count and measurement operations. In the second didactic design, students constructed a simple tool and examined it in several situations, then calculated the advantages and disadvantages. In the third didactic design, students designed a larger tool based on a proven model where in the process students used the comparison concept. The first didactic design, which was implemented then was revised based on the findings in the learning process. Based on the observation and analysis of learning result, this didactic design could improve students skills on critical thinking and creative thinking. Students could solve the problem during learning process where the students worked together and communicated. Students could also use their mathematic skills in solving problems in a social context.

Abstract
This review paper discusses the physicochemical characteristics of three different species of Palmae (Arenga pinnata, Cocos nucifera, dan Nypa fruticans) as alternative materials to produce galactomannans. Galactomannan has generally been widely applied and used in the food, pharmaceutical, cosmetic and paper industries. The major galactomannans of commercial importance in industries (guar gum, tara gum and locust bean gum) are limited in Indonesia. Therefore important to search for alternative renewable sources. The galactomannans were obtained by aqueous extraction followed by a precipitation with ethanol. The yield, monosaccharide composition and physicochemical parameters of the extracted galactomannans are different. The results confirm the possibility to produce galactomannan from various palms.

Abstract
Land use change that penetrate green area causes critical land. Critical land causes increase the erosion. Moreover, infrastructure development is increasing in the Tapalkuda area (Probolinggo, Lumajang, Jember, Bondowoso, Situbondo, and Banyuwangi). If erosion is higher, it will have an impact on the quantity and quality of water. For that, this research aims to analyze the effect of land use for erosion rates on 16 watershed of Tapalkuda in East Java using USLE method (Universal Soil Loss Equation) and GIS. The erosion rate was calculated based on the erosivity faktor (R) calculated from analysis of rainfall data, crop factor (C) and land use map analyzed by land use map 2014, the length and slope faktor (LS) calculated from the ASTER GDEM2, and erodibility faktor (K) obtained by soil type map. After the erosion rate was obtained, the comparised between erosion rate and land use that carried out using a correlation coefficient. The factor of land use analyzed are rice fields, settlements, fields, gardens and bushes.

Abstract
Abstract. The Mayang watershed at Jember Regency is one of the areas prone to drought in the dry season and flooding during the rainy season. Management of water resources is very important for sustainable agriculture in this area. This article focuses on the implementation of WEAP to study the specific water balance for irrigation water use. The Water Evaluation and Planning (WEAP) model use to calcul water supply and demand for irrigation. The FPR and LPR methode used to calcul irrigation water demand. Irrigation water supply is measured from the measurement site or intake of Irrigation water distibution systems. The result shows that inbalance of supply vs demand exists both for dry and rainy seasons. The lack of water supply during the dry seasons, force the reduction of water supply for irrigation. Therefore, the smart scenario for water management for irrigation need to be implemented during the dry seasons.

Abstract
Bedadung River is one of the Regional Strategic Rivers located in the Bedadung Watershed in Jember Regency. This river crosses Jember Regency with a length of 46,875 meters and is used as a source of raw water and irrigation as well as a source for PDAM Jember Regency. Along with the many activities of the community, the water pollution load is increasing. In general, the source of pollution comes from anthropogenic activities in the form of exposure to domestic waste, industrialization, population growth, pesticides and fertilizers, organic and inorganic waste, urban development and weak management systems. This study aims to analyze the environmental risks in the bedadung watershed based on water quality data using the DPSIR method. The DPSIR (Driver-Pressure-State-Impact-Response) Framework has long been used as one of the tools in environmental risk analysis that shows the existence of linear interactions between human activities-pressure and impact. In general, human activities represent drivers and human needs that can cause pressure on the environment and potentially cause certain negative impacts that need to be responded to to reduce them. The DPSIR framework to be used is Driver (industry, garbage); Pressure (changes in the chemical composition of water); State (physical and chemical characters); Impact (changes in water quality); Response (limiting waste disposal to rivers).

Abstract
Gmelina (Gmelina arboreaRoxb.) is the most widely planted tree species in Nueva Vizcaya province in the Philippines. Its role in local wood supply becomes more important as a consequence of the ban on harvesting naturally growing timber. More than 90% of the wood supply, based on reported transactions in 2013, is gmelina. Wood is coming from different planting configurations such as solitary trees, homegardens, road sides, riparian strips, small stands, and large plantations. While gmelina appears to the most important tree in meeting local demand for wood, the yield per hectare is low due to poor tree management and mismatch between species and site. Survey results indicate great potentials for tree improvement with effort coming from the tree owners themselves and supported by scientific approach in tree improvement. As one of the initial steps, research on ideotype, or conceptual model of an ideal plant, promises to play a key role. The study worked on gmelina timber ideotype. Between-tree-traits relationships were investigated in order to see what traits might be subjected for simultaneous improvement. Many significant relationships came out that would lead to defining the desired tree forms. Not a single form shall come out as combination of traits may result in increased in wood yield in tree or stand.

Abstract
The physical, chemical and sensorial characteristics of Chinese bun prepared from purple and orange-fleshed sweet potato paste were studied in terms of supporting local food diversification. The promising genotypes used were MSU 10003-07 (purple) and MSU 14014-84 (orange). The steamed tubers from both genotypes were analyzed physically and chemically (including anthocyanin and beta-carotene contents) then processed into Chinese bun with the level use of sweet potato paste 0% (100% wheat flour), 10%, 20% , 30% and 40%. The results showed that the proportion of sweet potato paste significantly affected the moisture content, color, hardness, porosity, volume development, and yield of Chinese bun. Based on physical, chemical and sensory analysis, the use of 30% purple and orange-fleshed sweet potato paste was preferred by panelists and had better quality than other levels. Using the selling price of IDR 3,000 per unit, the use of 30% purple and orange-fleshed sweet potato paste showed a slightly higher profit margin compared to 0% sweet potato paste. The production of Chinese bun from sweet potato was financially feasible to be applied further indicated by the value of B/C ratio which was more than 1 (B/C ratio 1.8). BEP price for Chinese bun from sweet potato production was IDR 3,828,269 with BEP unit was 1,276. This suggests that sweet potato is promising and feasible for Chinese bun production, thus needs to be promoted for its health benefits.

Abstract
Paddy fields are the main resource in fulfilling the main food commodities, namely rice in Indonesia. Conversion of paddy fields continues to occur along with the increase in population that requires settlements. Loss of paddy fields will have an impact on the loss of the value of rice production per hectare. In addition, there is a value of environmental services from paddy fields that we ignore. Some of the value of environmental services from paddy fields are flood control, supporting food security and preventing erosion and sedimentation. This study aims to determine the value of environmental losses from the loss of paddy fields in Magelang Regency which involves the value of the benefits of paddy fields environmental services through a system Dynamic approaches The law enforcement scenario to reduce conversion of paddy fields was expected to reduce the value of these losses. Simulation data were compared with real data for the last five years from 2013-2017 (Central Bureau of Statistics of Magelang Regency) and had values that were close enough to actual data with errors of less than 10%. The simulation results showed that the value of environmental losses in 2030 reached 173 billion rupiah by conversion of paddy fields about 2981.47 ha.

Abstract The number of wigs and false eyelashes factories in Purbalingga Regency that employing tens of thousands of female is an interesting subject to study from a gender perspective. For this reason, this study aims to examine the employment conditions in Purbalingga Regency in terms of business conditions, employment status, number of working hours and open unemployment rates. This research applies a descriptive quantitative approach by utilizing the 2017 Purbalingga Regency Gender Profile data which is supported by other related data. The data was then analyzed using a gender perspective. The results of the study show that many of Purbalingga residents, mostly females, work as laborers/workers/employees. Female workers dominate the processing industry business sector, while the male group is more engaged in agriculture and the like. Female workers also work more in the formal private sector or as migrant workers. Meanwhile, the unemployment rate of male is much higher than female. This is due to more open employment opportunities for female along with the number of wigs and false eyelashes factories in this region that prefer female workers to male ones.

Abstract
Kemiri Sunan (Reutealis trisperma) has great potential as a source of raw material for biodiesel production due to its high oil content. The oil is a non-edible oil that can be extracted using screw-press machine. In this study, a descriptive research with regression and correlation analysis was used to investigate the effect of feed material level on pressing performance and kemiri sunan oil quality. A variation of the feed material level (2, 4, 6, 8, and 10 kg) was fed into screw-press machine. The results showed that cylinder temperature and pressing time increased as the feed material level increased. The highest production (2.87 kg / hour) and yield (37.33%) capacity were obtained at 4 kg of the feed material level. Hence, increasing the feed material level did not affect the quality of the oil produced. Density, acid number, Free Fatty Acid (FFA), saponification number, kinematic viscosity and refractive index of oil produced ranged between 919.48-924.76 kg/m2, 30.82-47.79 mg KOH/g oil, 15.25-23.65%, 154.64 -186.84 mg KOH/g oil, 45.59-56.34 mm2/s and 0.00328-00.332 respectively.

Abstract
Seaweeds are increasingly used in Indonesian cuisines due to their nutritional value and health benefits. In contrast to these benefits, they accumulate lead during their growth and exhibit potential health risks upon ingestion. To overcome these risks, some appropriate pre-cooking treatments are desired to reduce lead content. Sample of Gracilaria sp. will be treated by soaking before cooking. This study applied the Taguchi method to determine optimum pre-cooking treatment conditions to reduce the level of lead in Gracilaria sp. The control factors included soaking temperature, time reaction, potential of hydrogen and water volume are used for this research. The levels of lead were determined by Atomic Absorption Spectroscopy (AAS). After these prosesses, lead contents were found to be successfully reduced and the results show that the optimal conditions during the soaking process can reduce the levels of lead of Gracilaria sp. in quite high percentages.

Abstract
Layer cake is one of the traditional cakes that is very popular with the community. The addition of Moringa leaves is expected to extend shelf life and nutritional components can increase. Moringa leaves are thought to contain antibacterial compounds which are the result of secondary metabolites. This compound consists of alkaloids, saponins, flavonoids, tannins, terpenoids and others. The purpose of this study was to determine the antibacterial properties of Moringa leaves added to layer cakes on pathogenic bacteria Escherichia coli and Staphylococcus aureus. The study was conducted in April-May 2019. Testing of antibacterial activity using the well method. The results showed that layer cake with the addition of Moringa leaves as much as 4% showed inhibition zones in E. Coli bacteria at 10.7 mm and S. Aureus at 9.7 mm highest when compared with the addition of Moringa leaves 1%, 2%, 3% . In both pathogenic bacteria tested on kelor that E. coli bacteria showed weaker resistance compared to S. aureus. This is indicated by the E. coli inhibition zone greater than S. aureus.

Abstract
Indonesia most popular commodities are strawberries which have high economic value. The indicator quality of strawberries can be seen from level of maturity. Auxin hormones have function to encode fruit ripening genes such as FaPYR1 and FaCHS. This aim of this study to detect FaPYR1 and FaCHS genes in strawberry plants induced by indole-3-acetic acid (IAA). The method used planting strawberries (Fragaria x ananassa "Crystal"), IAA induction by three different concentrations (10 ppm, 30 ppm and 60 ppm), genomic DNA isolation, quantitative testing, FaPYR1 and FaCHS genes amplification with PCR and morphological data analysis using SPSS. The results of the analysis using SPPS showed that highest yield of leaf length, leaf width, stem height and stem diameter at concentration of 30 ppm. The highest number of leaves was found at concentration of 60 ppm.The lowest morphological results were found in the control. The highest concentration genomic DNA was found in the red stage fruit with a treatment of 30 ppm and the lowest concentration was found at the white stage at 60 ppm. The results of amplification using PCR showed positive results for the FaCHS gene in all treatments and negative results on the FaPYR1 gene in several treatments.

Abstract
Production of antioxidant material by collecting phenolic compounds which contain of proanthocyanidins from red sorghum seeds has been designed using an agitation process. The perfomance of the process is influenced by the mass transfer of the functional compounds from the material to the bulk of solvent. Concentration value of the compound in the extract is the function of rotational speed and extraction time. The purpose of this research was to determine the optimum value of rotational speed and extraction time to maximize the extraction performance of antioxidant compounds from whole sorghum seeds. Optimization was performed from the extraction using distilled water as solvent in 60oC of temperature; 10 of sorghum-solvent ratio; 300, 400 and 500 rpm of rotational speed values and 90, 120, 150 minutes of extractions time and The optimum condition of extraction was determined using three level factorial design of Reponse Surface Methodology based on experimental data of the concentration value of proantocyanidin and phenolic compounds in the extract solution. The concentration of phenolic compounds in extract was maximum at 384.85 of rotations per minute (rpm) and 106,36 of extraction time, while the concentration of proanthocyanidin in the extract solution reached a maximum value in 417.17 of rpm and 143.94 minutes of extraction. The result by the equation from this optimization obtained 91.36% of R2 value for the phenolic concentration and 92.61% of R2 value for the proanthocyanidin concentration in extract.

Abstract
The impurities or dirt level is one of quality standard of crude palm oil processing, the level of impurities or dirt level is measured at clarification station especially at oil tank. Recent dirt level in crude palm oil at palm oil mill was still higher than standard level, it was about 0.036%. The objective of this research was to decrease the level of dirt content in Crude Palm Oil (CPO) production by modified the inlet pipe and installed automatic drain on oil tank. The method used in this research were analysed of feeding oil, level of dirt content and technical analysed by calculated the hydrostatic pressure on oil tank. This research showed that the average of dirt on feeding oil to oil tank was 0.056%. The average of dirt level on CPO production before modification was 0.038%, and after modification of inlet pipe, it was 0,031%. The rate of flow of oil into the oil tank was 20.2 tons/h, the volume of oil tank was 16.60 ton, while the retention time in the oil tank was 0.82 hours. Based on technical analysis, the results showed that hydrostatic pressure of CPO within oil tank was 16,770 N/m2 and hydrostatic pressure of sludge was 19,531.46 N/m2. This indicated by the CPO hydrostatic pressure that still smaller than the sludge hydrostatic pressure.
