Published: May 2020

Abstract
Great concern has been risen due to the harmful by-product formation in chlorine dioxide disinfection. To control the by-product formation, we need to know the factor that make a great contribution to generate by-product in drinking water treatment. The Fe2+, Mn2+, organic matter and algae are the most presenting matters that could cause the formation of chlorite; thus, they were selected as factors in the study. The results showed that the amount of by-product chlorite produced increased along with the increase of the concentrations of organic matter, algae and Fe2+ in water, but the presence of Mn2+ didn’t impact on the formation of chlorite. In addition, the interaction between Fe2+ and Mn2+ was observed, but no obvious interaction between other factors was found. So when the concentration of above factors exceed the standard, the chlorine dioxide is not recommended in any step of the water treatment.

Abstract
Parallel to the fast growing of population around the world, there has been a rapid increase in the amount of toxic organic waste that end up in water bodies, which is a threat to human health and to the environment. Because of this, there is need for the development of materials that are able to degrade them while using the sunlight. In this work, a Bi2O3/rGO/MoO3 composite was successfully synthesized by a solvothermal method under ambient pressure and low temperature. SEM, STEM and XRD techniques were used to characterize the morphological and crystallographic properties of the composite. It was demonstrated that the amount of GO in the synthesis of the composite has a great effect in the photocatalytic activity and it was found that the best ratio between Bi2O3 and GO was 300:1. The synthesized composite photocatalyst with ratio of 300:1 presented and enhanced photocatalytic activity for Rhodamine B as it was able to degrade around 70 % after 240 min under visible light irradiation, compared to pristine Bi2O3 that was able to degrade around 55 %. Results from this study illustrate the fabrication of a new ternary composite, which shows promising results for its application in the degradation of organic pollutants in water.

Abstract
A model describing the relationship between waste treatment method and greenhouse gases (GHGs) emission is proposed in this study. Three constituents, i.e., composting, reuse and recycle are analysed using extreme vertices mixture design to determine the model. Mixture design enables identifying of optimum combination of each constituent producing the lowest GHGs emission. Emission of greenhouse gases (GHGs) as a regress and were analysed how they change when the amount of waste changes. The result showed that there are four possible models. One best model is chosen for its least standard deviation, lowest P-value and the highest adjusted R2 which is 5.764 × 10-3, less than 0.005, and 0.9908 respectively. The model describes that lowest GHGs emission can be achieved by maximizing plastic recycle (into flakes), limiting composting and increasing paper, glass and metal reuse. Composting, reuse and recycle is proportional to the GHGs emission individually, while combination of two constituents is inversely proportional to GHGs emission. The lowest GHGs may be emitted from the plant is 0.107 Gg CO2 equivalent/year with the composition of constituents as followed: 14 % composting, 50 % reuse, and 26 % recycle equals to 1.3 m3, 4.7 m3 and 2.1 m3 waste from each method.

Abstract
The research aims to examine the structure and performance of the cayenne pepper supply chain. The study was conducted in Gorontalo from January to March 2019. The research was using the survey method. Data analysis was using descriptive and marketing efficiency analysis. The results showed 1) The structure of the cayenne pepper supply chain in Gorontalo Province consists of seven distribution channels. Sale of cayenne pepper by farmers through collectors (40 percent), wholesalers (26.67 percent), market traders (10 percent), and retailers (23.33 percent). The primary members of the cayenne supply chain consist of farmers, collectors, wholesalers, out-of-town traders, market traders, retailers, consumers, and agroindustries. The secondary members are farm shops, banks, transportation service providers, the Agriculture Service, and information media. 2) The most efficient distribution channel is channel six because the smallest marketing efficiency value is 3.17 percent. The cayenne pepper’s market in Gorontalo runs inefficiently because it has a price transmission elasticity value of 1.11 (Et> 1). It means the rate of change in prices at the consumer level is greater than the rate of change in prices at the farmer’s level.

Abstract
Traditional community has local wisdom in managing the relationship between man and man, man and nature, and man and God. The Japanese tradition gives the priority the relationship between man and nature because they believe that Nature is the most important place for human beings and gods. Therefore, in the Japanese traditional community, man and gods have to guard nature against damages. In order to conserve this local wisdom, they use myths, taboos, and rules. In today’s modern Japan, the Japanese still maintain their tradition so that it is commonly said that the Japanese are walking on two traditions: modern and traditional. In today’s highland farming in Japan, the Japanese farmers still perform ritual ceremonies such as rituals in planting rice plants, rituals in weeding and getting rid of pests, rituals in harvesting, and ritual after harvesting. Meanwhile, in the highland farming in North Sumatera, people’s tradition has changed. Today, farmers hunt wild animals such as birds, bats, and snakes because they damage ecosystem; but, as many wild animals are eaten by people, rats and pests/insects become flourish so that farmers now use a lot of chemical insecticide. In consequence, harvests become worse and farmers become poorer. Therefore, there is the difference in local wisdom between high land farmers in Japan and highland farmers in North Sumatera. In this research, the researcher did field research in Tohoku, Japan, and in Batak area, North Sumatera, in order to find out the differences. The theory of cultural comparative science was used in studying local wisdom of the farmers in these two areas. It is recommended that local wisdom be maintained for the local people’s welfare. This research was financed by the Japanese related research program, Sumitomo Foundation.

Published: May 2020

Abstract
Sago processing as local food continues, however, the sago pulp is not utilized optimally even unused so that there is a buildup of sago pulp waste which is increasing and can pollute the environment. This research aimed to investigate the potentials of sago pulp which could be used as the feeds of goat livestock, investigating the increase of the bodyweight of goat livestock; and investigating the effect of the use of sago pulp fermentation on the efficiency consumption, palatability, KcBK, given to kacang goat livestock. The research was conducted in Merauke Regency by using 12 kacang goats. The research was conducted for 2 months from May through July 2018. The goats were given three types of treatments and were divided into four groups (T0 T1 and T2) with the following model: T0 as the control group and received 100% of grass, T1 as the control + 20% of sago pulp fermentation and T2 as the control + 30% of sago pulp fermentation. The method used was Randomized Block Design (RBD), and the Variance analysis was used to analyze the efficiency of the feed of sago pulp waste, the level of palatability, the digestibility of dry matters (KcBK), and the body weight gain of the livestock. And in order to look at the effect of the feeds before and after the treatments, a T-test was used. The research results indicated that the increases in the body weight of the male kacang goats treated with 20% and 30% were 7. 05 kg and 12. 3 kg, respectively. The treatments using the sago pulp fermentation at the level of 20% and 30% were lower (5.9 kg) of the 30% group and (4.48) of the 20% group, compared to that of the control group (6.7 kg), A significant difference was also shown between the body weights of the male goats and female goats (12.3 kg and 5.9 kg respectively. The feed consumption of the kacang goats in the 30% treatment was 28.930 gr better than the control group which was 22.370 gr, and the treatment with 30% of sago pulp fermentation was more efficient 13.1 % compared to the control group which had only 7.87%. The KcBK in kacang goats showed an increase of digestibly of the dry matter in the 30% treated male goats were significantly different (63.25%) compared to that in the 30% female goats (59. 40%). This proved that the addition of sago pulp fermentation given to the kacang goats could increase the body weight, feed efficiency, palatability level and therefore it could be used as the substitute feeds in the dry season.

Abstract
Adsorption is one of the alternative media for processing wastewater. The study aims to use cocoa pods husk M45 (Theobroma Cacao) as a biosorbent in reducing Fe (III) and Cu (II) ions content in the laboratory liquid waste. This research was carried out through two systems, batch and continuous systems. The batch system was conducted to determine optimum contact time, optimum pH, and adsorption capacity, whereas the continuous system was intended to determine the adsorbent height and the maximum flow rate of laboratory liquid waste. The methods used in this study were adsorption and filtration. The adsorption results were analyzed by Atomic Absorption Spectrophotometer (AAS). The results found that the optimum contact time and the optimum pH for the adsorption of metal ions by cocoa pods husk M45 were 90 minutes and 6, respectively. The optimum flow rate of the wastewater in the continuous system was 6.166 mL/sec with an adsorbent height of 15 cm in the 2-inch adsorption column. The adsorption capacity of adsorbent based on the Langmuir isotherm was 11.074 mg/g for Fe (III) and 28.4091 mg/g for Cu (II).
