Sumbawa forest honey is honey produced by Apis dorsata bees. The problem faced is that Apis dorsata bees cannot be cultivated in stup and can only live in tall trees in the forest. This study aimed to determine the characteristics of Apis dorsata bees and Sumbawa forest honey. This research was conducted using a survey method, conducting field observations, interviews with several parties, and documentation. The research was conducted in Sumbawa Regency. The results of the study found that the survival of the Apis dorsata bee was highly dependent on forest sustainability. The taste and color of Sumbawa forest honey depend on the type of food or nectar consumed by Apis dorsata bees. This study concludes that Apis dorsata honey bees cannot be cultivated in stups, because this type of bee can only survive and thrive on tall trees in the forest. Sustainable harvesting techniques are carried out to sustain forest life and Apis dorsata bees. The price of Sumbawa forest honey varies based on its packaging, purity, water content, and distance traveled to collect it.

In the fish farming business, feed is the highest operational cost, which reaches more than 60% of the total production cost. Therefore, the fish feed can be processed independently to reduce production costs in aquaculture businesses. This study aimed to determine the survival rate and feed efficiency of red tilapia (Oreochromis sp) fed artificial feed with the addition of seaweed (Gracilaria sp). This research was carried out from June to September 2021 at the Integrated Laboratory of Khairun University. This study used four treatments, and each treatment was repeated three times. The treatment tried is A (Artificial feed with the addition of Gracilaria sp 10 gr); B (Artificial feed with the addition of Gracilaria sp 20 gr; C (Artificial feed with the addition of Gracilaria sp 30 gr); and D (Artificial feed without the addition of Gracilaria sp.). The research variables included calculating the survival rate (SR), Feed Conversion Ratio (FCR), and observing water quality during the study. The highest survival value was in treatment B at 97.78%, while the lowest was in treatment A at 73.33%. The highest feed conversion ratio was in treatment D, 1.97, followed by treatments A and B, 1.48, and the lowest in treatment C, 0.64. The results of water quality measurements during the study, namely DO, range from 6-6.8 in all treatments, pH ranged from 7-7.6, and temperature ranged from 28-290C. The best survival rate (SR) of red tilapia-fed artificial feed with the addition of Gracilaria sp seaweed was best in treatment B, 97.78%, and the best feed conversion ratio (FCR) was in treatment C, which was 0.64 g.

Studies on managing natural resources are currently attracting high interest in research. This is driven by the desire to find solutions to the problems that arise in managing natural resources to meet the needs of human life. Population increase and growth have caused the use of natural resources to be increasingly depleted, even close to scarcity. This research aims to reveal the forms of traditional wisdom of the people of Palembang in managing their natural resources to achieve their food sovereignty. The study was conducted on the people of Palembang City in December 2018. The research method is a qualitative descriptive method based on the analysis of data obtained in the field. The study results show that there is traditional wisdom in Palembang related to utilizing natural resources, including lebak lebung, bekarang iwak, ngaben, culinary pempek, and bekasam. This conventional wisdom is closely related to natural resource management, which increases food sovereignty. Traditional knowledge in Palembang society has two forms which are described as follows. First, local wisdom is in the form of Bekarang Iwak and Lebak Lebung. Conventional wisdom every year is still carried out by the people who live along the river as a form of natural resource management. Second, traditional knowledge in the form of culinary, which plays a role in fulfilling national food needs, namely pempek and bekasam culinary.

Utilization of seluang fish (Rasbora sp.) for food and collection by the community as decorative fish to serve as a source of income. The objective of research on the identification of plankton in the digestion of seluang fish from the Musi river downstream is to determine the type of plankton ingested by seluang fish, phytoplankton or zooplankton, which are seluang fish's natural food source. Prior to domestication, plankton variations can be exploited for cultivation efforts as a source of knowledge. The study was conducted in May, June and July 2019 at three stations. Samples of fish caught were observed in the Biology laboratory of the Faculty of Agriculture, University of Muhammadiyah Palembang. The fish is dissected using a scalpel, and its digestion is put in a small jar containing a 10% formalin solution. The fish digestion was formalized, transferred into a measuring cup with the addition of 10 ml of an aqueduct, stirred until crushed and observed under a microscope using a petri dish. The study results showed that the seluang fish species (Rasbora sp.) caught were Rasbora argyrotaenia and Rasbora borapetensis. In digestion, there are phytoplankton consisting of 4 classes, namely Cyanophycea, Chlorophyceae, Bacillariophyceae, and Eugleanophycea, while in zooplankton, only one class is found, namely Entomostraca. The composition of phytoplankton is greater than that of zooplankton of the class Cyanophyceae predominating by 34.7%. Thek-index of plankton diversity in digestion is moderate, the biota community is stable, and the dominance index indicates species dominate at each station. Water quality is relatively normal only at station 2, with the value of dissolved oxygen and low-value pH. The phytoplankton composition is greater than that of zooplankton.

Tofu is one of the foods in great demand by the public with affordable prices and fulfils the needs of protein in the body. The main obstacle to tofu production is concise shelf life. Tofu has a shelf life of one to two days without preservatives even though it is stored at a low temperature, which is a maximum temperature of 15°C. The way to reduce food ingredients' damage could be using natural origin and synthetic preservatives. The crown of god fruit can be used as a preservative of food from nature because it contains antioxidants and antimicrobials. This study aims to determine the Total Plate Count (TPC) of tofu stored with the fruit flour of the crown of god fruit. The method used is a Non-Factorial Group Randomized Design (RAK) consisting of six levels of treatment and repeated four times. The soaking of tofu in various powders of god's crown fruit as a natural preservative has a very noticeable effect on the Total Plate Count (TPC) after five days of storage. The highest number of microbes in the M0 treatment (without the provision of god's crown fruit flour) with an average value of 2.73x102 CFU/g and the lowest number of microbes in the M4 treatment (0.125g) with an average value of 0.93x102 CFU/g.

Tobacco is an important commodity in Indonesia because the tobacco industry makes a significant contribution to the Indonesian economy. Tobacco plants need nutrients to grow optimally. One source of nutrients for soil media is compost made from coffee grounds. These coffee grounds are often found as waste from the many coffee shops in Yogyakarta. The purpose of this study was to determine the effect of organic fertilizer made from coffee grounds on soil fertility and the growth of Vorstenlanden tobacco plants on different compositions of growing media. This research was carried out using a non-factorial completely randomized design with 5 levels A0 (Without giving coffee grounds compost), A1 (53 gr compost), A2 (105 gr compost), and A3 (158 gr compost), A4 (210 gr compost). The results showed that the administration of coffee grounds compost with the lowest amount gave the highest growth pattern compared to the treatment with the high amount of coffee grounds compost, and the application of coffee grounds compost did not show a significant increase compared to the treatment with coffee grounds compost. Compost of coffee grounds fermented for 2 weeks should not be applied to Vorstenlanden tobacco plants.

Compost of coffee grounds fermented for 2 weeks should not be applied to Vorstenlanden tobacco plants.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130468972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This study aims to determine the influence of the location of the buds and mechanical treatment after grafting on the growth of orange seedlings. The study used a Randomized Group Design (RAK), arranged factorially with nine combinations of treatments and three tests. The first treatment factor used is the budding eye system (P), consisting of 3 levels, namely P1: Fourth Budding Eye; P2: Fifth Budding Eye; and P3: Sixth Budding Eye. The second factor is mechanical treatment after grafting (K) consisting of 3 levels, namely K1: Rootstock Cutting; K2: Rootstock Restraint; and K3: Rootstock Bending. The parameters observed are the percentage of grafting of living plants, the time of bud exit, the number of leaf blades, the twisting of the stem of the grafting bud, and the length of the grafting bud. Based on the observations on the percentage of grafting that live after mechanical treatment of all budding eye location treatments, it shows that the fifth bud (P2) location treatment gives a higher rate of live grafting, which is 100% compared to other treatments. The treatment of the location of the fifth bud gives the best results against the time of bud exit, the number of leaves, the twisting of the grafting stem and the length of the grafting bud. Mechanical treatment of rootstock restraint after grafting gives the best results against the time of bud exit, the number of leaves, the twisting of the grafting stem and the length of the grafting bud. The interaction between the treatment of the fifth bud location treatment and the mechanical treatment of rootstock holding gave the best results against the growth of Siamese orange seedlings.
