Abstract

Sustainable cropping systems are part of a sustainable agricultural system in a broader sense. Some of the pillars of sustainable cropping systems commonly applied in Indonesia, such as vegetation succession, polyculture systems, cropping patterns, crop rotation, are discussed in this review. Furthermore, an analysis of the sustainable cropping system model was carried out: (1). Based on shade coffee plantations that are widely applied in Indonesian coffee plantations, (2). Based on the agricultural cultivation landscape in Bali Province known as the Subak system, which UNESCO has registered as a world heritage site, (3). Based on agroforest rubber plantations which are the local wisdom of Sumatra and Kalimantan.

Abstract

Fish protein hydrolyzate (HPI) is a dry protein dosage form with more than 60% protein content. HPI is produced from breaking down fish protein into simple peptides and amino acids through the hydrolysis process by enzymes, acids, or bases. The HPI snakehead product is expected to increase the product's added value because it can be applied in the food and non-food fields. This study aims to obtain the papain enzyme concentration that produces the best HPI through the total residual solids (%) test and the degree of hydrolysis test. In addition, to get the proximate value of HPI flour with the best papain enzyme. Based on the total residual solids test (%) and the degree of hydrolysis (%), the best value was obtained in the treatment of adding 20% papain enzyme. This resulted in a value of 13.25% water content, 0.045% ash content, 20.81% protein content, and 0.28% fat content.

Abstract

The decreasing population of snakehead fish (Channa striata) in nature needs to be preserved through cultivation. The use of probiotics in cultivation can support increased production. This study aimed to determine the effect of the frequency of probiotics on survival, growth, feed conversion, and body proximate in snakehead fish fry for 60 days. The study was conducted using an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatment is the frequency of giving probiotics, including once a day, twice a day, three times a day, and without probiotics (control). The results showed that the frequency of probiotic administration affected survival, growth, feed conversion, and proximate content of snakehead fish seed bodies. The best frequency is the provision of probiotics twice a day.

Abstract

This research was conducted for one year, which was divided into 4 quarters. The average of each quarter was used as a replication. This study aimed to determine the composition of purse seine catch and the effect of the length of the purse seine on the catch of fishers in the waters of northern Aceh. The sample in this research is purse seine which has a length of 800 m, 900 m, 1000 m, and 1200 m. The composition of the fishermen's catch during the study was skipjack, mackerel, lemuru, and layang. The test results using ANOVA in the treatment of the ring seine length group obtained the value of F-count is 40.275 or significant (0.000). The ANOVA test on replications obtained a value of F-count is 1.623 or a significance value (0.082), meaning that the length of the 1200 meter seine had a significant effect on the fishermen's catch, while the number of replications, namely the observation time during the study year, had no significant effect on the fishermen's catch.

Abstract

Waste containing heavy metals is an environmental issue and is a concern of many parties. Heavy metal ions/compounds come from various activities such as the metal production industry, metal plating, mining operations, and leather tanning. Metal waste is one type of inorganic waste that we often encounter in Final Processing Sites due to the continuous accumulation of waste and produce pollutants in the form of leachate. Leachate has the potential to contaminate groundwater. This study aims to explore and identify morphologically bacteria obtained from soil contaminated with leachate and can degrade hazardous and toxic materials on waste containing heavy metals. Soil samples were taken from the landfill soil at TPA Tamangapa, Makassar, taken as a composite sample, while the bacterial isolation used the steak plate method. The research stages included bacterial cultivation, morphological tests, and calculating the number of colonies using the Total Plate Count (TPC) method. The results showed that 10 pure bacterial isolates could grow on NA media enriched with 5ppm lead metal.

Abstract

This study aims to determine the resistance level of saline tilapia (Oreochromis niloticus) seeds obtained from tilapia broodstock that has been vaccinated with attenuated S. iniae bacteria against streptococcocis infection. This research was conducted in June-September 2020 at the Mini Hatchery Laboratory of the Department of Fisheries, Faculty of Marine and Fisheries Sciences, Hasanuddin University. The fish seeds used are 3-5 cm in size and 7-10 g in weight. The bacteria Streptococcus iniae were soaked in seeds for 30 minutes using concentrations of 105 CFU/mL, 107CFU/mL, 109CFU/mL, and without immersion. The seeds were then kept in a 40x25x20cm3 aquarium with a density of 50 seeds per aquarium for one month and fed at satiation. During the experiment, the media quality of the seeds was maintained within an acceptable range for the growth and viability of saline tilapia. The parameters observed were survival, RPS, and lysozyme activity in saline tilapia seeds. The optimal result that can increase the resistance of saline tilapia fry against Streptococcocis infection is at a concentration of 107 CFU/mL. This concentration can increase the survival rate, RPS, and lysozyme activity in saline tilapia.

Abstract

The North Luwu Regency Government has established a policy of developing horticultural agribusiness areas and strengthening the distance between the regional center and rural areas as producers of fruit and vegetable commodities. However, the support for the potential of natural resources is still a matter of debate between institutions. The purpose of the research was to describe the potential of eco-geographical resources and the level of importance of the institutional system in the development of horticultural agribusiness. The data that has been obtained were analyzed through two approaches, namely the data concerning the eco-geographical aspect which was analyzed through a regional complex approach. Meanwhile, data concerning social and institutional aspects were analyzed through the Interpretative Structural Modeling (ISM) approach. The results showed that all aspects of eco-geography including topography, marble level, soil type, and rainfall, were potential resources in horticultural development. Although all aspects other than the amount of funding, desperately need effective management. ISM analysis showed that horticulture development requires strategic program support, namely: (1) development of transportation facilities, (2) effectiveness of inter-institutional coordination, (3) program legitimacy and socialization, equal distribution of vision and mission of horticulture programs, (4) optimization of the role of institutions, (5) strengthening commitment between sectors, (6) increasing knowledge, and (7) developing strategic programs. Overall, the program will be easier to implement when it is supported by a strong institutional system.

Abstract

Consumer demand for mustard needs in Indonesia is increasing. Efforts to produce mustard greens use an aeroponic system to utilize nutrients in dosage and type correctly. The study aimed to determine the proper type of nutrition for the growth and production of two mustard greens in an aeroponic system. This study used a completely randomized design with two factors. The first factor is the type of mustard which consists of two levels, namely pakcoy and pagoda. The second factor to consider is the nutrition applied at three different levels: AB mix, liquid organic fertilizer, and foliar fertilizer. Mustard greens grew and produced significantly differently when grown in an aeroponics system. Other nutrients greatly affected all observed variables, including plant height, leaf number, leaf color, root length, fresh plant weight, and dry plant weight. The use of pakcoy mustard provides the best growth and production of mustard greens compared to pagoda-type mustard. Giving AB mix nutrition to mustard greens can provide the best growth and production compared to nutrition from liquid organic fertilizers and foliar fertilizers. The AB mix nutritional treatment with pakcoy mustard produced the best results in plant height, leaf number, wet weight, dry weight, and root length. AB mix nutritional showing the best leaf color variable with pagoda mustard greens.
