Abstract
Solenostemon rotundifolius is one of native tubers from Indonesia that has good potential as a flour source. Unfortunatelly, this kind of potato has poor quality and undesirable functional characteristic so that underutilized in food industry. Therefore, the processing of Solenostemon rotundifolius into flour product is needed to be modified in order to improve the quality, obtain the added value of flour, and enhance food product development using pre-gelatinization treatment. Pre-gelatinization is a hydrothermal process that initiated with boiling and ended with drying. This study evaluated the effect of pre-gelatinization treatment on physicochemical and functional properties of Solenostemon rotundifolius flour in optimum temperature and time of process (60°C for 7 minutes). The pre-gelatinization treatment produced 89,58 ± 1,47 % yield of flour, reduced the density (0,55 ± 0,02 g/ml) and lightness of flour (71,30 ± 0,14 L value), and declined the amylose content (18,21 ± 1,22 %) compare to the natural flour, while increased the moisture (8,32 ± 0,31 %), ash (3,95 ± 0,06 %), protein (3,43 ± 0,23 %), fat (0,47 ± 0,01 %), starch content (65,11 ± 0,30 %), and amylopectin (46,90 ± 1,51 %). The differences in physicochemical and functional properties were observed among the pre-gelatinization Solenostemon rotundifolius flour with respect to all of parameters. Thus, Solenostemon rotundifolius flour revealed the potency as an alternative flour for food diversification and can be used for substituting wheat flour in various food product.

Abstract
Indonesia was ranked as the 2nd country in the world in 2015 with the most plastic waste disposal from the land to the ocean. The government has made many efforts to reduce the amount of plastic on the market and try to divert the use of food packaging from non-plastic materials. One effort that can be done is the use of bioplastics where this material is easily degraded by nature. This experiment uses avocado seeds as based material of bioplastic, sorbitol, and glycerol are mixed with the melt intercalation method and ZnO powder is added 1%, 2%, 3%, 4%, 5%, and 6% to strengthen the mechanical properties of bioplastics. Tensile test results show that the addition of ZnO 1% to 3% can increase the tensile strength of bioplastics while the addition of 4-6% reduces the tensile strength up to 39%. Storage at room temperature for up to 3 weeks shows increased tensile strength values but shows signs of damage to the 4th week. Water absorption data obtained that the highest water absorption is in bioplastic samples without ZnO content with value 86% and the smallest water absorption is at 6% ZnO content of 40%.

Abstract
Siwalan is palm type plants, which one of the prime agricultural commodities in Tuban Regency. Siwalan production has increased from year to year. Abundant production provides great potential for siwalan farmers and groups of siwalan processed enterprises into other processed products. Legen drinks and siwalan fruit are products that become typical souvenirs of Tuban and are favored by local tourists. However, problems related to product hygiene and low storage are a challenge for the siwalan palmers. So far, technological innovation has not touched on the processing of legen or siwalan fruit, so that the development of its marketing is very limited and it has not been able to broader the welfare of society. The purpose of this activity is to examine the relationship between aspects of attitude towards food security with aspects of business performance and the importance on strengthening GMP (Good Manufacturing Practice). The results of the activities show that there is no significant relationship between aspects of attitude towards food safety with aspects of business performance. This is consistent with the findings found that most of the craftsmen ignore the aspect of food safety especially in the legen beverage production process. Some producer also add food additives and carry out further processing to extend the shelflife of legen. This has an impact on the taste of legen and also in terms of food security. Therefore, socialization and training related to GMP is a key factor for improving business performance and achieving sustainable development.

Abstract
Empty fruit oil palm bunches (EFOB) is one of the abundant lignocellulosic biomass in Indonesia. However, high lignin content in EFOB has becoming one of the obstacles in valorising it as bioenergy resources, as it is hardly breakdown by the microorganisms. Therefore, pre-treatment is often needed to enhance the biodegradation process of organic content in EFOB. This study was aimed to investigate impact of biological pre-treatment using fungi on the EFOB characteristics and to estimate the biogas production and its conversion to electricity. The biological pre-treatment on EFOB is besieged to enhance the utilisation of EFOB as bioenergy resources. In this study, EFOB was treated using Phanerocheate chrysosporium under standard condition and incubated for 7 and 14 days. The results showed that fungi pre-treatment was able to reduce the amount of lignin concentration, which indicating that more lignin was broken down into other easily degradable organic material compounds. The calorific values of EFOB after pre-treatment also increased alongside with the increase in incubation time, which also indicating a higher energy potential. Estimation on electrical potential based on CHNS values was also indicating the same trends. Treated EFOB has more electricity and heath production compared to that of untreated EFOB. Further research, however, is still required to have in-depth understanding on improving the efficacy of biogas production by incorporating a green pre-treatment using biological pathway approach.

Abstract
Rabbit considered as an ideal meat-producing animal, has a short life cycle, short gestation period and prolific.The capacity of feed conversion is high. Due to digestive physiology, can convert about 20% of feed protein into edible meat. Furthermore, this meat considered very healthy, have a rich of protein, low in fat, and cholesterol. However, the consumption of this meat found very low due to small production by the farmer. There is a farmer group focused on the production of rabbit meat in Malang, namely “KelompokKelinci Malang (KKM)”.However, the production rate was still low due to inability to manage feed efficiency. Therefore in this community engagement program, easy and feasible feed management was introduced by this group. The training program was conducted an on-site demonstration. Prior to the training, focus group discussion was held to investigate the actual problem and expectation was fully discussed. The results indicated that the practice had given a new sight of all the target participant,especially in feed management and breed selection of the rabbit farming. Feed management affected the body and sex maturity so that maximum reproduction can be achieved. Performance of the breed can be measured using letter size, mothering ability, and low mortality. Effective feed management may increase the meat production. Finally, the feed management and breed selection are very important to find out the best performance.

Abstract
Malang is a regency that has a high coffee production potential of 7,703 tons annually (BPS East Java, 2014). Of the several types of coffee-producing one of the famous is the District of Dampit. Dampit District since the Dutch era is known as a coffee producer. Now Dampit District is still known as the main coffee producer (East Java Time.Com, 2016). Activities to improve coffee quality consistently to produce premium coffee have been started by the Sridonoretno Association. At present the results of premium coffee production from the SRIDONORETNO Association are directly absorbed by the community of coffee shops and lovers in Malang (± 80 shops in Malang) and several shops outside the City of Malang. The strategy adopted by the Association in managing groups for the production of premium coffee is in a way; 1. Building a processing group in a group that has high enthusiasm 2. Making the group leader as the head of the yield processing unit (UPH) and quality controller. 3. Building Koprasi for managing venture capital and marketing.

Abstract
Population growth in Indonesia, nowadays often bringing many trigger of many social conflicts and it has many consequences of it. The problem which caused by these gap of population is likely creates another problems; such as malnutrition caused by poverty in society, abortion, baby boom and so on. There is a way to eradicate this problems, targeted for young family named KB Programs. KB Program are contains health promotion and counselling for using contraception among productive ages in young marriage, which provides into several methods, both are for men and women. Previously, women contraception are most popular rather than contraception methods for men but for now, this participation for men acceptor is increasing since there are contraception counselor named PLKB accompanied the local community. This research presenting on how health promotion running well for men acceptor through PLKB counseling and what is the men perception about their active participation into KB Programs. Research was conducted based on qualitative methods using area sampling for 15 men in Batu City, East Java. Applying Deconstruction theory from Jacques Derrida, research found that 1) there were still a stereotype that contraception only used mostly for women; 2) Counseling from PLKB are proven for upgrading men perception for their health issues and decided to get involved on KB Program by choosing MOP; 3) Men perception are being improved through MOP methods in contraception, and they tried to enlarge this knowledge by spreading this health promotion to others in Batu City using social media.

Abstract
The education and health sectors are placed in the top position of Indonesian goverment priority scales, since both have positive relationship and should be developed together. Education and health sector collaboration actually creates a health awareness for children as early as possible, which starts at the age of primary school. Unfortunately, the drinking water treatment equipment that can be operated continuously with low cost or energy for elementary students are never found in Malang, Indonesia. So this study aim is to install the drinking water treatment device based on membrane filtration and UV sterilization at primary school and also to analyze of teachers and students satisfaction toward the equipment applied. In this study, the importance performance analysis (IPA) and consumer satisfaction index (CSI) are used as a method for analyzing of teachers and students satisfaction. The data was collected from 100 respondents and 13 attributes were analyzed in this research. The IPA results showed that attribute categorized into quadrant I or priority for improvement only maintenance of the equipment. Attributes that are categorized into quadrant II that need to be maintained are appearance, freshness, taste, volume precision and quality testing in laboratory. While attributes that are categorized into quadrant III or second priority for improvement are flavor, color, volume, hygiene of water and affordability. The attributes that are categorized into quadrant IV are practicality of use and the ergonomic design. The consumer satisfaction level by using CSI is 76% which means that consumers are satisfied with water produced by drinking water treatment device installed in their school

Abstract
Urban forests have aesthetic functions and social functions that refer to the quality standards. In the urban landscape, space is inseparable from the problem of traffic noise and other activities. The sounds are composed in unity, and form interactions in the acoustic environment of urban forests. A sound composition that interacts with a particular landscape is called a soundscape. The term soundscape can also be interpreted as an acoustic environment that is understood and felt by individuals. Urban noise can cause city forest soundscapes to be less comfortable and less aesthetic, so their function as green open spaces is not fulfilled. This study aims to make improvements to the soundscape based on the quality of green open space standards through noise control and find out the improvement formula that is most preferred by the subjects. The standard quality of green open space can be pursued through sound masking, active noise cancellation and convolution in sound signal conditioning. The improvement results were tested on 30 respondents by comparison tests and then identified with subjective environmental acoustic parameters, namely autocorrelation function (τ1, Φ1) and dynamic range (DR). Efforts to improve quality based on the quality of green open space the most preferred by respondents are sound masking and ANC with birds singing with scores of 4.44 and 2.78, respectively. Based on the results of identification of traffic noise treated by ANC and sound masking with birds chirping obtained DR values = 32.35 dBA, τ1 = 0.73 s, and Φ1 = 0.03.

Abstract
Ngancar Subdistrict is a production center for pineapple varieties Smooth Cayyene and Queen that supports the superior product of Mount Kelud tourism in Kediri Regency. SMEs "Murni Mandiri" is one of the producers of pineapple juice brand "Namako" with a production capacity of 50 liters per day. The monthly sales turnover is 3-4 million with a profit of around 25-30% so it is feasible to be developed. During this time, the production process uses manual equipment ranging from boiling, filtering, and packaging in the form of cups and bottles. The demand of product has reached 100 liters per day, even during the Lebaran season and holidays can reach up to 100 times. The problem point faced by SMEs “Murni Mandiri" is the low production capacity due to inadequate production equipment so that consumer demand cannot be maximally fulfilled. For this reason, it is necessary to transfer technological innovations that will improve efficiency and effectiveness in the production of pineapple juice in the form of Integrated Filter Machines and Cup Sealers with Appropriate Technology scale that meets LLM (Low Technology, Low Investment and Marketable) requirements so that they are easily adopted by SMEs. The advantage of this machines is that it can implement a continuous pineapple juice production system and directly evaluate the resulting quality which is integrated from cooking, filtering, controlling and packaging in one continuous flow so that the quality and quantity will be more effectively controlled.

The result of study shows that independent macroprudential policy rule generating the most minimal value of loss function and the higher response of interest rate smoothing than Plain Vanilla Taylor rule and others model. This suggests that macroprudential instruments as a buffer in the optimal of monetary policy minimize the loss function of the central bank. In this case, the interest rate instrument is used to reach the stability of inflation and output. Furthermore, macroprudential policy is used to respond to credit growth. This is in line with Tinbergen principle.

Abstract
The purpose of this study is to describe the level of knowledge and strategies for the introduction of technology for making compost and natural dyes of ikat woven cloth of the Dayak community in Ensaid Panjang village, Sintang, West Kalimantan. This community service activity adopted action research with a project-based learning approach. Action research activities start from the initial survey of community needs. Furthermore, the activity implementation team compiles preparations in the form of debriefing to students of real work lectures, preparation of materials and equipment needed for practice. A total of 52 respondents were determined by snowball sampling technique. Key informants in this study consisted of the Head of Ensaid Panjang Hamlet, the Betang traditional house elders, and the Ensaid Panjang community representatives. Furthermore, the introduction of technologies for making compost and natural dyes of ikat woven cloth was done by lecturing, simulation, demo, and direct practice methods. The results showed that three indicators showed a significant increase in understanding. These consisted of skilled at the process of making natural dyes from local plant species that can be used as dyes for woven cloth; the the process of making compost from household waste, litter and livestock waste; and institutional roles that help the process of making and marketing woven cloth. A significant increase in understanding indicates that the action community empowerment activities have been successfully implemented. In general, the average increase in understanding and achievement of the community by 11%. Particularly, the understanding of composting has improved by 51%.

Abstract
Local Water Supply Utility (PDAM) of Salatiga planned to build three new wells to meet the need for clean water and increase the number of customers in Salatiga. The plans for the construction of the new wells are located in Randuancir, Kumpulrejo and Noborejo Sub-Districts. The groundwater aquifer layer in Noborejo Village is detected using the Electrical Resistivity Tomography (ERT) method, while the determination of the depth of aquifer layer will be controlled by the results of Vertical Electrical Sounding (VES) data processing. 4 ERT lines and 4 VES points were acquired in 2017. The processing results show that water-containing layer tends to have a lower resistivity value. In the study area, 2 types of aquifers were found, namely unconfined aquifer (usually exploited using dug wells), and confined aquifer which are generally located on the deeper depth. Unconfined aquifers are identified with a lower resistivity value than its surroundings (20-80 Ωm) with an average depth of 25 m on all lines. Whereas confined aquifer has a higher resistivity in the range of 90 Ωm. However, confined aquifers are only found with certainty in Line 1, while in other Lines the possibility of a confined aquifers existence is smaller.

Abstract
Hibiscus rosa-sinensis L. is a plant that has been cultivated as an ornamental plant, especially in Indonesia. Universitas Indonesia, located in Depok, has 10 variations of H. rosa-sinensis in size, shape, and color of flowers. The flower shape consists of 3 types, namely, single, double, and crested. In this study, We reported the comparison of leaf morphology from several types of H. rosa-sinensis L. Twenty leaves from each variety were used for morphometric measurement, and light intensity data from each location of the plant variety was also collected. There are two locations, Universitas Indonesia (UI) Campus Area and Citayam. The results showed that two crested peach in Citayam exposure by different light intensity has significantly different in leaf surface area but no difference in stomata surface area. Big Single Red and Double Pink located in UI exposure by the same light intensity has the same leaf surface area and stomata surface area. Comparing Small Single Red Citayam and Small Single Red UI exposure by different light intensity has significantly different in leaf surface area and stomata surface area. Two Crested Peach in UI exposure by the same light intensity has significantly different in leaf surface area and has the same stomata surface area. In this case showed that light intensity can influence the variation of leaf morphology of several Hibiscus rosa-sinensis L. flower types, but not all flower types.

Abstract
Sukodadi is a village that has great potential of diversity, especially in religion and faith (Islam, Hinduism, Catholicism) which are embraced by its citizens, and even there are also local faiths that can coexist. The practice of tolerant life of Sukodani society can be used as a role model for the development of a harmonious life in Malang, but the great potential has not been realized by the village community. This condition is caused by several factors, including low human resources, especially related to potential tolerance, lack of encouragement from the government, and other public facilities. Based on those problems, Doktor Mengabdi Team efforts to empower and assist the community by two steps, namely: observation and focus group discussion by participatory action approach. The results show two things. Firstly, to realize an educational destination, the village youth (Karang Taruna) can make tolerance tourism packages to promote tolerance villages both conventionally and digitally. The realization is that the Doktor Mengabdi team collaborates with academics and practitioners to train them regularly and equip them with knowledge of tolerance, homestay management and tourism amenities, planning tourism promotions and tour packages, so that can benefit local residents. Secondly, the PKK members will be trained to make batik by collaboration with Celaket Written Batik (BTC) and Soendari batik gallery. This program can becomes a socio-cultural laboratory in tolerance learning from local wisdom with a more specific theme, namely the Development of Economic and Educational Tourism Areas.

Abstract
Asteraceae, also known as the Sunflower Family, is one of the largest and successful flowering plant species beside Orchids and Legume families. This family is often considered taxonomically difficult, mainly because of its vast numbers and cosmopolitan distribution. This family also displays floral diversity in tribes, hence the study was conducted to compare the stages of Asteraceae inflorescences (capitulum) and fruit structures of six species (Blumea lacera, Cyanthillium cinereum, Mikania micrantha, Emilia sonchifolia, Bidens pilosa, and Porophyllum ruderale) that belong to Inuleae, Vernonieae, Eupatoriae, Senecioneae, Coreopsideae, and Tageteae respectively. The inflorescences and fruit were observed using Dinolite devices and Dinocapture 2.0 applications. The results indicate that there are variations in the flower development stage, with a range of stages, 10-19. The flowering stage divided into four, namely pre-anthesis (the inflorescence is still in the bud form and green); beginning of anthesis (the buds start to open, and the corolla begins to appear); anthesis (marked with a fully open corolla); and senescence (characterized by a change in the corolla into brown and dry out). The six species observed have achene (cypsela) fruit with a size range of 3.8 -18.3 mm with distribution accessories. All the five species studied have fruit accessories in the form of pappus, except for Bidens pilosa. The fruit pappus in five species have different sizes in the range of 2.8 – 10.3 mm - the most extended fruit pappus belong to Porophyllum ruderale.

Abstract
Asteraceae is one of the cosmopolitan flowering plants spread in various regions, including Indonesia. Tridax procumbens, Eclipta prostrata, Eleutheranthera ruderalis, and Synedrella nodiflora are commonly found at Universitas Indonesia Campus, Depok. The research was conducted to describe the development stages of flowers and fruit forms from the four species of the Heliantheae tribe. Samples were taken by purposive sampling technique at several locations at Universitas Indonesia Campus, Depok. All stages of flower buds start from the smallest (± 2 mm) until the dry up fruit stages are collected and observed using the Dinolite device and the Dino capture 2.0 application. The results showed that there were variations in the number of stages of inflorescence-fruit development in the four species observed, with a range 8-16 stages and the largest size in the range of 4-9 mm. The flowering stage divided into four groups, namely pre-anthesis, beginning of anthesis, anthesis, and senescence. In the pre-anthesis stage, the inflorescence is still in the bud form and green; at the beginning of anthesis, the buds begin to open, and the corolla begins to appear; the anthesis stage is marked with a fully open corolla; while the senescence stage is characterized by a change in the corolla into brown and dry out. The four species observed have achene (cypsela) fruit with sizes ranging from 3-4 mm. The fruits can be divided into two groups, with and without a distribution accessory. Seed distribution accessories are winged peripheral, lanceolate shaped central, capillary bristle, and reduced pappus.

Abstract
In the last 10 years, Mount Bromo has erupted three times; 2010, 2015 and 2019. However, it is unique that Tengger peoples are reluctant to evacuate even though Mount Bromo is erupting and releasing volcanic material such as stones and dust. Mount Bromo itself is a mountain made by caldera with an area about 10 square kilometers. This makes Mount Bromo relatively safe while an eruption occurs because volcanic material with a large size and weight will fall around the caldera, only dust that is blown by the wind will be continued as far as miles from the crater of Bromo which depends on the direction of the wind. Using the smartphone application as the Mount Bromo information facilities is one of an effort so that people and tourists can activate if an eruption occurs. There is important information about features made in the application such as shelters distribution, evacuation routes, health centers, photos, videos, and other important informations. Assesment results to the application interface, the information conveyed, and also the features offered show that the application is very useful and gives a new perspective in conveying accurate information to the public and also tourists. The level of community satisfaction is also quite good with the services provided by the Bromo preparedness application. Great expectations from the public and also respondents can see Mount Bromo further through CCTV cameras that are directly connected to the Android application.

Abstract
Bemisia tabaci is one of the economically important pests of many cultivated plant. This pest also plays as a virus vector that causes high yield losses. The objective of this study was to determine non-preference for oviposition in soybean genotypes to B. tabaci and the damage intensity caused by this pest. The experiment was conducted in Indonesian Legumes and Tuber Crops Research Institute in 2018. 24 soybean genotypes were evaluated in screen house with three replicates in which infested naturally by B. tabaci. The result showed that egg and nimph populations were found on low, middle, and upper leaves. Generally, the highest population was found on middle leaves that ranged from 5-89 individuals/ trifoliate, followed by lower leaves (5-30 individuals/trifoliate) and upper leaves (0-19 individuals/trifoliate). Totally, the population of B. tabaci ranged form 12-125 individuals/plant. The highest population was found on genotype G100H/9305//IAC100-271///Grob-36-2 (125 individuals) and the lowest population was found on Kaba/IAC100//Brg 63///Grob-392-1 (12 individuals). Moreover, the leaf damage intensity caused by B. tabaci ranged from 8.6-38.3%. The highest damage intensity was found on G100H/9305//IAC100-271///Agro-803-1. However, the lowest damage intensity was found on G100H/9305//IAC100-271///Grob-42-3. Therefor, Kaba/IAC100//Brg 63///Grob-392-1 indicated as genotype that showed non-preference for oviposition based on egg and nymph populations and categorized as moderately resistant against B. tabaci based on leaf damage intensity. Whitefly attack characterized by the presence of black sooty mold on leaf surface.
