Abstract: This study aims to determine the effect of forest bee honey on changes in male sex of sword platy fish (Xiphophorus helleri). The benefits of this study were to determine the appropriate dose of honey for changes in male sex and how the survival rate of sword platy fish larvae was. This study was conducted using a completely randomized design (CRD) with five treatments and three replications, namely Treatment A: Control (Ordinary Feed), Treatment B: Dosage of 3 ml of honey mixed into 100 g of feed, Treatment C: Dosage of 4 ml of honey which is mixed into 100 g of feed, Treatment D : Dosage of 5 ml of honey mixed into 100 g of feed, Treatment E : Dose of 6 ml of honey mixed into 100 g of feed. The results showed that mixing honey into feed gave a significantly different effect on the percentage of male sex ratio where Fcount > Ftable (5.15 > 3.48). Where the best dose is found in treatment E: 6 ml of honey mixed into 100 g of feed with a percentage of 66.05%. While the lowest percentage value is in treatment A (Control) with a total percentage of 40.79%. For the survival rate, mixing honey into the feed had no effect between all treatments. The percentage of survival rates is still in the range above 50%. The range of water quality values is the temperature ranges from 26.55-27.52 0C, pH ranges from 7.02-7.06 and dissolved oxygen ranges from 5.13-5.31 ppm.

- Volcanic Soils: Their Characteristics, Management Practices, and Potential
Sollution for Water Pollution
Authors: Rendy Anggriawan, Nuryana Ariska Salsabilla, Imelda Ayu Prahesti
Pages: 18 - 29
Abstract: Volcanic soils are formed from materials originating from volcanic eruptions, and with various pedogenic processes occurring, volcanic soils have unique physical, chemical, and biological characteristics. This paper aims to review the characteristics of volcanic soils, constraints, management practices, and their potential as adsorbents for contaminants. The paper was based on secondary information using a systematic review. The studies carried out include identifying manuscripts, analyzing report data, critically assessing the topic, and combining the results of relevant published manuscripts. The issues raised include data on volcanic soils, management practices, water pollution, and using volcanic soils as an environmentally friendly adsorbent. Colloidal compounds in the clay fraction of volcanic soils generally contain active Al and Fe compounds, allophane, imogolite, ferrihydrite, or Al/Fe-humus complex, and together with opaline silica. The volcanic soil material produces a pool of Al and Fe solid phases with high reactivity, which contributes to the unique physicochemical properties of Andisol. The main problem chemically is the high adsorption of phosphate and nitrate ions which causes the fertilization process to be inefficient. The main problem affects the adsorption of phosphate and nitrate on agricultural lands, so fertilization becomes inefficient. However, the high reactivity of volcanic soils can be used as a basic pollutant adsorbent. This is quite a promising opportunity, given the wide distribution of volcanic soils, so this resource is a very prospective candidate as an adsorbent material in water purification.

- Of Development of Small-Scale Integrated Farming Design: towards
Optimizing Agricultural Learning Media
Authors: Ni Kadek Ema Sustia Dewi, Arif Umami
Pages: 65 - 75
Abstract: Learning about integrated farming could be done by visiting site locations directly. This is a problem for universities that are located in urban areas. The distance of the integrated agricultural location from the campus often raises a significant cost burden. Therefore, providing a learning model around the university would be more efficient, and students could interact and practice directly. The design concept was compiled based on a literature review. The design was produced by direct observation at Condongcatur experimental garden, then continued SWOT analysis. The design was created using software based on the information gathered. The design development included a general description of the experimental garden, landscape biophysical aspect, concept planning, and design. The resulting design was then validated by experts descriptively using a questionnaire. Meanwhile, user acceptance was measured qualitatively through an interview. Based on the results obtained, theoretically, a small-scale integrated farming design has been successfully compiled and met the requirements to be developed as an agricultural learning model. The design also received a good response from the management, which would then be followed up in the long-term development plan of the experimental garden.

Abstract: The purpose of this study was to determine the effect of goat fertilizer and TSP fertilizer on the growth and yield of chrysanthemum (Chrysantenum morifolium R.), conducted at the green house of Pudak Lestari Agrotourism, Pancasari Village, Sukasada District, Buleleng Regency, Bali, from May to in August 2022. This study used a Randomized Block Design (RBD) consisting of 2 factors arranged factorially. The first factor tested was goat manure (K), which consisted of 4 dose levels, namely: K0 = 0 tons/ha, K1 = 15 tons/ha, K2 = 30 tons/ha, K3 = 45 tons/ha while the second factor was TSP (T) fertilizer consisting of 4 dose levels, namely: T0 = 0 kg/ha, T1 = 175 kg/ha, T2 = 350 kg/ha, T3 = 525 kg/ha, each of which was repeated 3 times so that there are 48 trial plots. The research results showed that the interaction between goat manure and TSP fertilizer had no significant effect on all observed variables. Treatment of goat manure had a significant effect only on leaf area, flower diameter, long weight of flower stalks, fresh weight of economic flowers and other variables had no significant effect. The highest economic fresh weight of flowers was obtained from goat manure at a dose of 45 tons ha-1, namely 48.25 g, an increase of 23.97% when compared to no goat manure, namely 38.92 g. The TSP fertilizer treatment obtained the highest plant height and flower diameter in the TSP fertilizer treatment at a dose of 525 kg ha-1, namely 12.67 cm and 10.18 cm compared to that without TSP fertilizer application, namely 10.71 cm and 9.40 cm.

Balangan Regency
Authors: Alfi Maulana, Tuty Heiriyani, Ronny Mulyawan
Pages: 84 - 89
Abstract: Rice (Oryza sativa L.) is an important food crop because it produces rice which is a staple food source, as in Indonesia rice is the main commodity in supporting people's food. One of the causes of rice production is the application of fertilizer, the application of fertilizer by farmers in the study area is still general in nature due to limited knowledge of data. This study aims to determine rice production due to the use of inorganic fertilizers in Batu Merah Village, Lampihong District, Balangan Regency. The method used in this research is descriptive quantitative. Data collection on rice production by way of surveys and questionnaires to 10 respondent farmers in the field, to determine the yield of rice production in 10 paddy fields with an average area of study area, around (± 9.7 ha) or 9,798 m2. The farmers used inorganic fertilizers twice, before planting with a dose of 75 kg/ha of urea, 30 kg/ha of SP-36, and 30 kg/ha of NPK fertilizer. The second fertilization when the rice plants are two months old, with a dose of 50 kg/ha of urea, 20 kg/ha of SP-36 fertilizer, and 20 kg/ha of NPK fertilizer. Rice production results from the area of land that has been converted, yields an average of around 2.99 t/ha. The main factor of high and low production yields is due to the different area of paddy fields owned by farmers.
