Abstract
In order to study the thermal performance of amorphous silicon photovoltaic double-skin façade (a-Si PV DSF), the experimental cabin of a-Si PV DSF was designed and established in Nanjing, China (118.80° E, 32.06° N). The thermal performance of a-Si PV DSF was experimentally tested, and the influence of a-Si PV DSF on the heat gain of the cabin was studied. Using EnergyPlus to establish a simulation model of the experimental cabin, the model was verified by experimental data, and the verified model was used to simulate and analyze the heat transfer performance of a-Si PV DSF. The results show that a-Si PV DSF has better cooling and heat insulation effect during the day than at night, which can effectively reduce the heat gain of the external wall of the building. A-Si PV DSF has good energy-saving effect in different climate areas and reduce the heat gain of the external wall by more than 38%.

Abstract
Rice is consumed by most people, especially in Asian countries. Rice consumption resulting left oever rice. Rice also has a low storability and resilience because it is susceptible to microorganisms. It will change to spoiled rice if leave it at room temperature. Both kinds of rice become mull. Hence, it required further processing of spoiled rice and leftover rice. One of the alternatives that can be done is by converting rice into maltodextrin. Maltodextrin is widely used in various industries including food, beverage, chemical and pharmaceutical industries. Similar to starch, maltodextrin is widely used as a thickener as well as an emulsifier. This research was conducted to determine the quality of matodextrin resulting from spoiled rice and leftover rice. Rice converted to maltodextrin by amylase enzyme and dried by using a spray dryer. The treatment is replicated 3 times and the data is statistically analyzed by using T-test. The parameters are water content, ash content, and color. The results showed that the water content of maltodextrin from spoiled rice was 1.6% and the leftover rice was 1.35%. In addition, the ash content resulted 0.37% and 0.48% for spoiled rice and leftover rice, respectively. The color test conducted using a chromameter shows that the brightness is suitable with the expected color of the maltodextrin.

Abstract
This study describes the problem of high dependency on rice consumption in Papua while Papua has several local foods as alternative sources of carbohydrate. The study focuses on Papua province as the region that has many potential on local-non rice food like corn, cassava, and sweet potatoes, which then selected as the study objects. A ten-year series of data from 2006 to 2015 was obtained from BPS (Central Bureau of Statistics) and analyzed in this study. The results show that the development of local food was relatively slower in Papua Province compared to the national level, except for fish development. It is observed that the program to increase rice production is very intensive while the program to increase local food production has not been a concern of the local government. Programs to increase production, develop cultivation, production, and processing technologies are biased to rice production, resulting in the food diversification program trough local food development is likely difficult to be realized. Papua Province has a comparative advantage in local food because it is supported by the potential of natural resources and the culture of local community. Local food must be encouraged and promoted as–a major, healthy food source and at the same time, support the realization of food diversification programs in Indonesia.

Abstract
Bamboo has excellent potential to be developed as a building material, pulp, textile, carbon sink, water-storing, and water-holding. An alternative method for plant propagation is by in vitro micropropagation (tissue culture). The cultured explants were able to grow to be a new individual having shoots and leaves. Murashige and Skoog (MS) medium concentrations solely were significantly affected by the number of shoots. The addition of thidiazuron (TDZ) into media resulted in the best percentage of shoot number (80%) in all concentrations of media. Using low concentration, TDZ was able to produce more leaves than other cytokinins. The appropriate concentration of MS medium and the plant growth regulator for Betung bamboo’s tissue culture is ¾ MS with the addition of 3 ppm TDZ.
