Published: October 2020

Abstract
Energy needs to become an inseparable part of the community’s living needs, along with the rapid increase in development. The supply of electricity is carried out by PT PLN (Persero), as an official institution appointed by the government to manage electricity problems in Indonesia, so far it has not been able to meet the community’s need for electricity as a whole. So, it is necessary to develop the potential for renewable energy such as hydropower. Potential water resources that can be used as sources of electrical energy such as the Hydroelectric Power Plant and Micro-Hydro Power Plant. Based on these problems, this research was conducted to analyze the potential of micro-hydro using the Geographic Information System method with the Soil and Water Assessment Tool (SWAT) model and the application of spatial pattern plans to increase potential areas in micro-hydro development in Kelara Watershed, South Sulawesi. This research uses the Soil Water Assessment Tool (SWAT) model approach and the calculation of hydraulic power. Classification of land cover in 2015 in Kelara watershed with vegetation is 6,469.45 ha (16.81%) of the total area of the watershed. The results showed that with 2015 land cover conditions, there were 22 sub-watersheds with the potential for micro-hydro development from 83 sub-watersheds in Kelara Watershed. Assuming a minimum of 10 kW of power is generated at any time, 12 sub-watersheds are obtained, which can be used for micro-hydropower plants. The implementation of the spatial plan in 2031 can reduce the number of potential sub-watersheds based on minimum discharge. The condition of land cover in 2015 amounted to 22 sub-watersheds, while in the spatial plan, there are 21 potential sub-watersheds.

Published: October 2020

Abstract
Bamboo is one of the plants in the family of grass (Poaceae). The need for bamboo is increasing, but it has not been matched with innovative cultivation. Thus the population of bamboo in nature is decreasing. Induction of bamboo shoot can be used as an alternative method for plant multiplication in a short time through tissue culture. Additional plant growth regulators such as Benzyl Amino Purine (BAP) and Indole Butyric Acid (IBA) are needed to induce bamboo shoots. The data were analyzed using the R Statistics software. Furthermore, the results showed that Murashige & Skoog (MS) media with the addition of 1 ppm of BAP and 0.5 ppm of IBA (M5) was the best combination to induce the number of shoots, shoot height, leaves length, and number of leaves in pring tutul.

Published: October 2020

Abstract
Concrete began to use substitute materials to reduce the brittle nature. Substitution material is material that can replace concrete material both coarse aggregate, fine aggregate, and cement with other materials, such as Portland cement with steel slag, broken stone (coarse aggregate) with pumice and other stones. One of the benefits of the concrete material substitution method is that it can use organic waste. Organic waste can be in the form of residual production or usage, one of which is the candlenut shell which is a waste of candlenutThe candlenut shell is a new potential that can be developed and utilized even greater. Of course It can increase the economic value of the candlenut shell which has only been known as a waste material from the candlenut. The composition of the candlenut shells are CaO, SiO2, Al2O3, MgO, H2O, Fe2O3. When all reacts, there will be residual SiO2 that has not yet reacted to form a silica derivative reaction with CSH-2 gel resulting in a denser CSH-3 gel, which will increase the cement paste and aggregate. The purpose of this discussion is to determine the compressive strength value of candlenut shell concrete at 0% and 30% variation on the plates using Ultrasonic Pulse Velocity (UPV) at 28 days. The method used is experimental by testing samples / specimens in the form of reinforced plate size of 50cmx25cmx12cm with wet curing and dry curing methods with a variation in age of 28 days. Concrete compressive strength testing is done using UPV tools. The results of this discussion are the compressive strength of 30% candlenut shell variations on the application of the plate shows that the quality of the concrete produced in the wet curing reaches 18 MPa or equivalent to the quality of the K 225 concrete and the dry curing is only 14 MPa or equivalent to the quality of K175, while the variation Candlenut shells 0% (normal concrete) reach 28 MPa on wet curing and 24 MPa on dry curing. This shows that the plate with a variation of 30% candlenut shells are still able to achieve concrete quality II for use in structural work.

Fashion and commercialism in architecture
Authors: Deapati AK , Wikantari R 
Published: October 2020

Abstract
Architecture and fashion are different in the product. The high consumptive nature of fashion followers turned it into a commercial field for the designers, in contrast to the architectural products that can be worth up to billions of money, which makes architecture difficult to renew its design in a short time. The western fashion cycle that changes every season, four times a year, is inversely related to the cycle of architecture that can last for years. Those things affected two phenomena of the recent issue of architecture and fashion, that (1) many buildings were found to be designed using fashion cycle principle that is always new and different since it can save the production costs, and (2) to satisfy their desire in design, some architects decided to switch the profession to become a fashion designer so they can produce more design in a year. This research focused on the first issue that aims to describe fashion as a commercial periodical concept that can be applied in the architectural field to increase the commercial value of the building and its environment through an example from the Western architecture in recent years. The paradigm used in the study is the post-positivistic type with qualitative research. The analysis technique used is a descriptive-explanative type through the non-textual content analysis of visual data (images, photos, and videos). The results showed that the essence of fashion as ‘clothes’, which alternated to always create a new image, is expected to continuously create innovations that can enrich the design field with less funding. On condition which did not affect the characters, the application of cross-concept and crossprofession had positive impacts on the development of architecture.

Published: October 2020

Abstract
The needs in irrigation water of farmers in farming management is higher nowadays. In addition to the demands in fulfilling the water needs in rice production activities, the ability of farmers to manage the water resources well also become a necessity. Saptana, DKK (2001), stated that water and irrigation resource management is considered as one of the key components for the improvement in food security. Irrigation water management depends on the level of farmer’s association of Farmers Water Users (P3A) as an organization that has the authority in the utilization, development and management of irrigation water. This research aims to analyze the relationship between participation factors with the participation rate of P3A members in the management of irrigation channels in Maros Regency. This research uses a qualitative-quantitative approach. Results showed that; age, land area, distance between paddy fields and irrigation channels is a factor that has a real connection with the participation rate of farmers in the management of irrigation channels. While the number of family members are dependents and education levels do not have a real connection with the participation rate of farmers in the management of irrigation channels.

Published: October 2020

Abstract
Food security is one out of primary concerns of national government and sub-national government for the sake of realizing national food security goal. There is a various policy has been implemented such as human capital enhancement, innovative technology, and preventing land conversion. However, the transformation of economic activity leads conversion from agricultural to non-agricultural land, thus, we analyze that there is dilemma in food security policy. This research uses new institutionalism perspective to analyze the dilemma of the policy. The national security policy could not fill the key problem of food security, where rational choice of actor is less out of the government concerns, therefore, the policy is less powerful in controlling the conversion of agricultural land.
From ideas to actions: the influence of policies and stakeholder perceptions in the development of sago technopark in Palopo City, Indonesia
Authors: Nuryanti Dewi Marwati , Salman D , Rampisela Dorothea Agnes , Sahide M Alief K. 
Published: October 2020

Abstract
The development of sago technopark in Palopo City is a manifestation of the Memorandum of Understanding (MoU) between four local governments to advance sago in the Luwu region. In the MoU, Palopo is designed to be a thematic park that combines entertainment and education, Luwu is the center of SMEs areas in processing sago, North Luwu is a producer of seedling for sago cultivation, and East Luwu became a center for developing the technology of sago-based rehabilitation for post-mining land. For this reason, the government of Palopo City has formulated the Regional Action Plan (RAP) of Sago Technopark in Palopo (STP). This paper aims at analyzing the influence of this policy in the realization of the STP as well as to analyze stakeholder perceptions towards the development of the STP. The used methodology is the analysis of policy content to understand the substance of the program/activity, and the stakeholder analysis is used for capturing their perceptions about the urgency of STP. It was concluded that the policy affected the availability of infrastructure and detailed operational plans of STP however it was insufficient to realize the ideal type of a functional STP. Although stakeholders’ perceptions generally consider the importance of sago technopark, their contribution is still low. Furthermore, the management unit has not yet been formed to encourage the participation of various stakeholders in the realization of the STP idea.
