Riverbank settlements tend to have slum environments found in urban areas. Many factors such as land use change, increasing demand, population growth urges the use of urban space as residential land. Currently in the city of Malang; as a research location; has many settlements on the banks of the river, such as along the Brantas river, namely in Betek, around Tarekot (city recreation park) and Jodipan. Many efforts from the government to change the values and perceptions of the community to have a positive connotation, with thematic village programs. This relationship is reciprocity and formed the concept of tourist villages, such as the Kampung Warna Warni and the Kampung Biru Arema (KBA). This village has an identity which has the blue nuance as an icon of the Arema football club. This village successfully built the economy of the local population but also left a negative footprint on the environment. For example, visitor behavior that does not dispose of trash in its place or a mismatch of planning applications to visitor behavior. Its influence certainly has an impact on the environmental health of the KBA community itself. This study aims to determine the pattern of visitor behavior towards KBA locations and environmental conservation efforts. The study was conducted qualitatively with the behavior mapping method and time budget, and associated with the concept of sustainable landscapes for environmental health. The results of this study are recommendations for the use of environmentally responsive open space in accordance with the behavior of visitors to tourist attractions.

Galang Island region's potential development into a tourism area depends on the physical potential, diversity of flora and fauna and activities that support the economic sector for residents around Galang Island. There are two types of ecotourism development recommendations, one concerning conservation which aims to preserve ecosystems and the second is the use of natural beauty as tourism background and facilities that support the surrounding resident's economy. The problem is how the two tourism recommendations can work together and what kind of synergy the recommendations are like. Through identification stages of the flora and fauna types and analysis of the economic activities of residents around Galang Island, produce a mapping of the potential that can be developed into a tourism area. In the ideation stage, the potential analysis can be realized by functional zone, namely conservation zones, recreation zones and their relationship to regional boundaries and the synergy relationship formed through the circulation concept. By the zones and circulation concept, the visualization phase will be more detailed explaining by the atmosphere that was formed as a synergy form in the Galang Island region design

Global warming has changed global, regional and local climate conditions. Global climate change is caused, among others, by the increase in greenhouse gas emissions (GHG) due to various activities that drive the increase in the earth's temperature. Given that climate is a key element in the metabolic system, plant physiology and crop ecosystems, global climate change will adversely affect the sustainability of agricultural development. The impact of global climate change is the increasing population of pests on agricultural crops. One of the soybean pests whose population is increasing due to the increase in air temperature is the Bemisia tabbaci infestation. Increased pest populations of Bemesia tabbaci infestation in soybean crops cause dwarf leaves of dwarf plants and threatens to increase soybean production. Efforts to overcome the impact of global warming is mainly due to increased pest populations, it is necessary to think and seek breakthroughs to anticipate the explosion of pest populations in soybean crops, among others by: the optimization of natural control, physical and mechanical control and cultivation techniques. The combination of techniques or tactics of the optimal component of soybean pest control technology is established on the basis of appropriate information knowledge about soybean pest, ecosystem and socio-economic based on IPM approach.

Ultisol is the main type of land in Kalimantan, Sumatra, Papua and Sulawesi, with an area of almost 45.8 million ha or 25% of the land area of Indonesia. Ultisol has a relatively high acidity (average pH 4.5), high Al saturation, reaching 60%. The efforts to increase the fertility of ultisol soils such as the addition of organic materials such as Empty Oil Palm Bunches (OPEFB) and CFA (Coal Fly Ash) or Coal Fly Ash (CFA) improve the physical properties of Ultisol soil. Use of CFA that exceeds the limit can cause pollution especially copper (Cu) and lead (Pb). One way to recover soil from heavy metal contaminants with Phytoremediation technology, mustard (Brassica juncea L.) is one of the plants that easily absorb heavy metals so that it can be used as a Phytoremediation agent. The aims of this research to determine the use of CFA and OPEFB to fix up the ultisol soil and heavy metal content absorbed by plants. This study used Completely Randomized Design with 3 replications. The results showed that using of CFA and OPEFB can increase the available P so that it can increase the growth of mustard plants and absorption of heavy metals. By using the dozes of 54.54g CFA and 18.18g OPEFB (C3K1) can increase P- available at 181.67 m kg-1 . The uptake of heavy metals Cu and Pb in mustard plants is very high. The highest uptake in Cu reached 192.03 mg kg-1 , whereas in Pb it was 80 mg kg-1 . This number is still very high, so it is dangerous if consumed.

Animal feed should ideally be inexpensive and not competing with humans. Ampas know is a waste of the manufacture of tofu that contains protein and high energy. Its use has problems due to the existence of antinutrient and cannot be kept long. Lactobacillus Plantarum is a lactic acid (Gram-positive) bacteria used in the fermentation process to improve the quality of feed. The goal of fermentation is to remove the anti-nutrients that exist in the tofu pulp and increase the content of Isoflavone (Daidzin, Glycitein, and Genistein) and Isoflavone is a source of antioxidants important to growth. The study uses a Completely Randomized Design with 5 treatment of microbial culture concentrations of 1%, 5%, 10%, 15%, and 20% (V/w), respectively repeated 3 times. The result of analyzes in the pulp of tofu fermentation suggests that fermentation by Lactobacillus Plantarum can increase the content of Daidzein, Glycitein, and genistein with the highest value resulting from the use of L. Plantarum 20% respectively 191.21 + 24.9 μg/g, 85.96 μg/g, and 120.82 μg/g. It can be concluded that the higher the use of the concentration of L. Plantarum in tofu pulp can increase the levels of isoflavone, so it is advisable to conduct research with the concentration of L. Plantarum higher in tofu pulp

This experiment was conducted to evaluate the effect of various fat sources and their combination (coconut oil and soybean oil) on growth performance of broiler. A total of 80 one-day old female 1-d-old Arbor Acres were randomly assigned into four groups (4 treatment) with 10 replicates (6 birds per pen) within 42 days. The experimental groups consisted of four treatment of diets: 1) a basal-diet containing beef oil (BO),  2) a basal diet containing coconut oil (CO), 3) a basal diet containing soybean oil (SO), and 4) a basal diet containing coconut oil and soybean oil (CO+SO) as were used. Performance data were obtained during the feeding period. The result was shown that using combination of medium chain fatty acid and unsaturated fatty acid (CO+SO) were increased growth performance demonstrated by highest bodyweight (59.62 g) compared with other treatments (P 0.05) throughout the experimental period (0-42 days). The lower group for feed conversion ratio was obtained in the diet containing beef oil (BO) compared with other groups (1.32; P 0.05). Feed consumption and bodyweight have significantly different (P 0.05) but not different for feed conversion ratio (P 0.05). It can be concluded that feeding combination CO+SO in the diet may improve the performance of broiler.Beef oil; broiler; coconut oil; growth performance; soybean oil
