Buletin Loop of the Politeknik Pertanian Negeri Samarinda is one of the most active centres of scientific work in agriculture in the Samarinda. Problems are attacked from two distinct points of view: the economic, in which the object is to show how crops may be produced a little more cheaply than at present, and the scientific, the problem being investigated for the sake of the general principles it may bring out. Two sets of bulletins are therefore issued, the popular bulletin, intended for farmers, dealing mainly with local problems, and always from the local point of view, and the research bulletins. The popular bulletins are fully equal to any others in the United States, and much ahead of anything we publish here for farmers; in the series before us the subjects dealt with include land drainage, curing of seed corn, control of various weeds, draft-horse judging, a discussion of the methods of paying for milk at cheese factories, and so on. The research bulletins are the scientific papers of the staff; as usual in the Samarinda, each paper is published separately, and there is no common journal in which they all appear.

Abstract

Along with the development of industry and the increase in population, the need for chilies has also increased. This shows that more than half of the chilies that have been harvested have the potential to be wasted or not utilized optimally. So the dryer designed and made is a type of bulb heat-based dryer, namely a chili dryer that can use heat energy from the light rays of the bulb. With this dryer, it is hoped that there will be an increase in production capacity. Apart from that, the product obtained will be of good quality, namely having relatively clean chili quality. The research design used in this research is to use one treatment, namely for 10 hours from 08:00-18:00 and testing the specified parameters at a time interval of 120 minutes. In this research, the method used was an average calculation with one treatment repeated 3 times, symbolized P1= chili product 1, P2= chili product 2, P3= chili product 3. Bulb heat-based dryers can work well according to their use. This tool produces an average temperature of 52.44°C, and the highest temperature reaches 60°C. The capacity of this bulb heat-based dryer has 6 shelves and can accommodate 4,800 g of chili, with each shelf able to accommodate 800 g of chili.. Based on tests on the parameters that have been carried out, the average water content in chilies is 57.3354%. This result is still very high compared to the SNI for the water content in dried chilies of 11%.

Abstract

Tempoyak, a fermented food made from durian, is a popular seasoning in Malay communities in Malaysia and Indonesia. Produced using low-quality durian, it serves as an alternative to prevent spoilage. Tempoyak has functional benefits as it contains lactic acid bacteria (LAB), a probiotic providing digestive health benefits. Research on East Kalimantan's durian lai explores its potential for tempoyak production. The study, utilizing a Completely Randomized Design, examined salt concentrations and fermentation times. Optimal quality was achieved with a 5% salt concentration and a 7-day fermentation period, yielding favorable organoleptic results, with "liked" ratings for color and texture, and "somewhat liked" for aroma and taste. The hedonic quality included an orange-yellow color, sour aroma, salty taste, and soft texture. The total LAB reached 4.1 x 108 CFU/g, meeting probiotic criteria, with a pH of 3.85.

Abstract

The use of the main growth medium in the form of wood sawdust in mushroom domestication is still higher than that of other organic materials, even though its availability is limited, so efforts need to be made to find a growth medium composition that minimizes the percentage of sawdust use. The purpose of this study was to determine the comparison of treatment 1 (80% teak sawdust, 10% bran, 5% tapioca flour, and 5% agricultural lime) with treatment 2 (70% teak sawdust, 15% bran, 10% tapioca flour, and 5% agricultural lime) on the percentage of growth and mycelium growth of white oyster mushrooms.  Composting of growing media was carried out for 5 days, then baglog making was carried out, after which the baglog was sterilized for 4 hours. After sterilization, the baglog was cooled and inoculated. After inoculation, the baglog is incubated to grow mycelium. Then, after 15 days, data collection and calculation were carried out. The parameters measured were the percentage of growth and mycelium growth of white oyster mushrooms in baglogs. Results showed that the percentage of growth and mycelial growth of white oyster mushrooms in treatment 1 is better than in treatment 2. Reducing the percentage of the main growing medium of teak sawdust and adding the percentage of additional growing media of bran and tapioca flour has a negative impact on the number of baglogs that grow mycelium (percentage of growth) and the growth of white oyster mushroom mycelium. This means that reducing the main media of teak sawdust and adding additional media is not the right growing media composition for domestication of white oyster mushrooms, so it cannot be used as an alternative growing media composition to reduce the use of wood sawdust.

Abstract

The increasingly rapid development of technology provides changes in several aspects. Technological advances in this era apart from providing many benefits also provide challenges. One project that can accommodate the zoomer generation in following technological developments is the use of terrarium cultivation. Terrariums fulfill the 3 R principles, namely Reduce, Reuse, Recycle. By planting a terrarium, it means saving water, saving land, and reducing air pollution (Reduce), also reusing unused containers such as used jars (Reuse), and using animal waste as compost (Recycle). The facts in the field are that students as the zoomer generation have received training and socialization on terrarium cultivation, but the level of adoption (acceptance) of students regarding socialization and training on terrarium cultivation varies, therefore a study was carried out to what extent the level of adoption of the results of training and socialization in the application of cultivation terrarium for the zoomer generation. The data collection method used was a survey method with research subjects of the zoomer generation, namely 54 active students. The data collected is categorized tabulatedly and then analyzed descriptively qualitatively. This data analysis uses measurements of observation indicators using a "rating scale". The results of the research show that the level of adoption of zoomer generation innovations in terrarium cultivation, if seen from the latest average, the adoption level is in the very high category. Differences in the level of adoption of terrarium cultivation innovations in the zoomer generation with a very high level of knowledge, a very high level of persuasion/interest, a very high level of decision, a very high level of implementation and a very high level of confirmation. If you look at the overall score, it is in the very high category.

Abstract

This research is motivated by the fact that currently remote sensing technology continues to develop, both in terms of data collection and processing. This is characterized by the existence of data collection techniques using unmanned aerial vehicles for aerial photo mapping. The advantage of using this technology is that it is effective and efficient both in terms of time and human resources for mapping in areas that are not too large. Another advantage is that it can produce clearer photos, because the plane's flying height is below 400 meters above ground level so that during the shooting process there is no cloud interference. The aim of this research is to create an aerial photo map at the Samarinda State Agricultural Polytechnic, validate objects in aerial photos and in the field, and provide information about the area, boundaries and topography of the Samarinda State Agricultural Polytechnic campus area. The implementation of activities and research objects is the Samarinda State Agricultural Polytechnic campus area. This research uses a small format aerial photo mapping method using a Quadcopter, making it easier to determine where to start taking off and landing. With a Quadcopter vehicle, grounding problems are no longer an obstacle. The research results showed that photography carried out with a Quadcopter at a height of 200 m above the ground produced an area of 28.17 Ha and a spatial resolution of 8.40 cm/pixel. The validation results in aerial photos and in the field using drones have a small difference between 0-4 cm with an average of 1.625 cm/photo. From the digitization results of campus objects, there are 30 objects on campus with a total area of 2.67 Ha. As for the topography results in the campus area, the highest point is 107.5 meters above sea level and the lowest point is 60 meters above sea level.
