Black Soldier Fly (BSF, Hermetia illucens) is an insect species that potentially can be used as a protein source for broiler nutrition. This study aimed to evaluate different inclusion level of BSF on broiler performance and blood metabolites by integrating various data from related studies using meta-analysis. Total of 12 studies that comprised of 31 data points were integrated in the database. Parameters observed included Live Weight (LW), Average Daily Gain (ADG), Daily Feed Intake (DFI), Feed Conversion Ratio (FCR), blood metabolites, and carcass proportion. The database was statistically analyzed by using mixed model method. Different studies were considered as random effects, and the level of BSF was treated as fixed effects. The model statistics used were the p-values and the Akaike information criterion. The significance of an effect was stated when its p-value was < 0.05. The results revealed that BSF feeding had significant linearly reduction effect on LW, ADG, and FCR of broiler (P < 0.05) and significant linearly increase effect on DFI and carcass proportion. However, BSF did not significantly affect on blood metabolites of broilers. It can be concluded that BSF negatively affect the performance of broiler.

The limited capacity of human resources (HR) that is competent in their field often causes the less than optimal utilization of the marine and fisheries resources in Indonesia. Maritime and Fishery Vocational Schools (MFVS) can be the solution to this problem, as they are expected to generate capable and competitive human resources; thus, utilizing and sustainably managing the vast marine resources in Indonesia, and in turn improving the efforts taken to advance Indonesian people’s welfare. However, the level of employment for MFVS graduates in Indonesia is still limited to large scale fishing activities. Additionally, since the launch of Moratorium License of Fishery Commerce of Fishery States in the Republic of Indonesia (56/PERMEN-KP/2014) by the Indonesian Ministry of Marine and Fisheries (IMMaF), most fishery companies have ceased to operate. The study aimed to determine the impact caused by this regulation against the level of employment of MFVS graduates, as well as the scheme of policies that should be applied to maximize the human resources in the field of marine and fisheries. This research used a qualitative method, where the descriptive analysis was used as a primary tool of analysis. The results of the analysis indicated that the trend of employment of MFVS graduates shifted after the enactment of this policy. The lack of synergy between policies in the field of marine and fisheries and policies in the field of education and transportation resulted in the difficulty of MFVS graduates to achieve a good career in this field..

Yogyakarta is Indonesia’s province with the highest inequality at the Gini ratio of 0.417. This research brings into focus inequality in Yogyakarta and inequality distribution by regions and the economic sectors. Methodologically, this research uses the descriptive quantitative analysis model to spell out inequality distribution. The analysis units are regions and the economic sectors at provincial and district/city levels. The parameter used is the Theil index with the approach of inequality of between-region, between-sector, within-region, and within-sector. The results exhibit that at the provincial level, Yogyakarta has a Theil index of 0.686. The region with the highest inequality is Bantul (0.737), whereas other areas come with severe inequality (> 0.5). In regard to between-region inequality, the highest inequality distribution is between Sleman and Kulon Progo and Gunungkidul. At district/city levels, the highest inequality is identified in the agricultural, trade, and industrial sectors. Finally, the highest inequality distribution is between the construction sector and the agricultural, trade, and industrial sectors.

The purpose of this study is to perform the techno-economic analysis of photovoltaic system utilization for lighting and cooling of Ferry Ro/Ro 500 GT. The world is facing a dilemma of increasing dependence on fossil energy with decreasing supply. This situation must be anticipated by all sectors by energy efficiency (EE) and utilizing renewable energy (RE). Especially for RE in the transportation sector, ships as consumers of oil energy can also take advantage of solar energy sources, for example for lighting and cooling. For that purpose, five steps must be taken. First, determine the design specifications. Second, determine the specifications of components of the PV system. Third, calculate the power required for lighting equipment. Fourth, calculate the power required for the cooling system. Fifth, make an investment comparison for propulsion systems between diesel engines and photovoltaic systems. The results show that the energy required for lighting and cooling system as well as for propulsion systems can be placed in the deck area of 148.8 m2 for all system components, such as; PV modules, charge controllers, batteries, and inverter. This study can provide an overview of the use of PV system in designing the environmentally new or renovation ships.

The need for beef in Indonesia continues to increase. In 2020, it will require imports of 300 thousand t of meat or the equivalent of 1.7 × 106cattle a year. To overcome the problem, the biogas-energized livestock feed making machine (copper) was designed. The advantage of this copper is the process of making the livestock feed can efficient and effective. Results of the calculations, known that with increasing miller rotation output, the resulting capacity shows an increase. Also, it can use drive motors that are available on the market with a power capacity of 50 W. Hence; this machine is very efficient in the use of electricity, high economic value, convenient and easy move to other places. Electricity for the engine is designed with renewable energy, namely biogas from co-digestion substrates namely animal feed waste, kitchen waste, cow dung and excreta disposal from septic tanks. This co-generation is expected to improve the life of the breeders

Energy demand increases in line with rapid technological advances. Research on the harvesting of renewable energy continues to be done to make efforts to convert heat energy, which is very abundant in our daily environment. Thermoelectric technology is an alternative source in answering energy needs and can produce energy on a large and small scale. Thermoelectric technology works by converting heat energy into electricity directly, or from electricity to cold. This research presents an experimental study conducted to find out the thermoelectric characteristics of the TEC in the reversal function, with heating and cooling tests on each side of the TEC type thermoelectric element, carried out to obtain the voltage value as the electrical potential generated from this element. The result is thermoelectric potential to generate DC electricity but is very limited in the function of maintaining a heat source on the hot side element. This research then proposes thermal metamaterial that functions as a collector of thermal energy in the method of converting thermal energy into DC electrical energy for the application of low power consumption communication systems.

Film editing is a vital part in th2Department of Computer Science and Engineering, Toyohashi University of Technology, Tempaku, Toyohashi 441-8580, Japane post production process of a film. One of film technique is the montage editing technique, created by Sergei Eisenstein. Even so, Kuleshov’s “Effect” may be considered as the starting point of montage theory. Juxtaposition is a film editing technique that combines two or more shots to generate ideas or create thoughts. A montage can be a juxtaposition of two or more shots, but generally refers to a juxtaposition of several shots to describe a stretched event or a solidified time. This paper presents the experiment of juxtapositioning several shots in the scenes of a montage movie, In the Future, where the shots that have been sorted in the first version of this short film, then a few shots are exchanged positions in the second version then result a different story.

The Covid-19 pandemic has caused an economic crisis that has spread across all sectors. The one of food crisis does not originate from a supply crisis but from a purchasing power crisis and distribution barriers. Agribusiness cooperatives take an important role to support farmers in managing finances and food stocks. This study aims to analyze the performance of agribusiness cooperatives in East Java Province to maintain their identity and developing business strategies in the Covid-19 pandemic. The sample in this study were three agribusiness cooperatives in Nganjuk Regency. Methodologically, the analysis is carried out by assessing the identity of the cooperative using the Development Ladder Assessment method and assessing the corporate business strategy. Both measurements were carried out to obtain an overview of the strategic policy choices of agribusiness cooperatives in facing the crisis. Some identity issues include membership management and member participation which has decreased during the pandemic due to limited social interaction. During the pandemic, agribusiness cooperatives also strengthened business strategies with implement a human resource strategy by restructuring human resources and rearranging wage and incentive policies. The financial strategy is also carried out by tightening credit terms and increasing capital from external sources.

National soybean production needs to be increased for meeting domestic soybean demand and suppress soybean import, through improving cultivation techniques including using improved varieties. Study aims to evaluate the feasibility of improved large-seeded soybean cultivation. The study was carried out in 2021 in Tegaldlimo Sub-district, Banyuwangi Regency, East Java, Indonesia. Data were collected through survey and field observation on the application of existing and recommended technologies. The results showed that 5 new improved large-seeded soybean varieties introduced, namely Dega 1, Devon 1, Denasa 1, Denasa 2, and Detap 1 resulted in higher production than local Martoloyo. The recommended technology was more profitable than the existing as indicated by B/C ratio >1. The introduction of new varieties that are different from Martoloyo attracted 100% of farmers to adopt. In terms of crop and seed physical appearances, farmers prefer to Devon 1 due to its similarity appearance to Martoloyo, except the seed size. In term of economic feasibility, Devon 1 is profitable to be cultivated with B/C ratio of 1.5.
