Abstract

A field experiment evaluated the effect of different doses of composted organic fertilizer made from rice straw on the yield of three local aromatic rice varieties of Luwu Regency in the safe growing season (rainy season). The local aromatic rice varieties were Ngappa, Sassa, and Latimojong varieties, and four doses of composted organic fertilizer from rice straw, namely 0, 4, 8, and 16 tons/ha, were used as treatment variables. The experiment was laid out in a Completely Randomized Block Design (CRBD) with two factors and three replications. At harvest, data were collected on various characters that contributed to the yield of aromatic rice. The results showed no characters were affected by the interaction of variety and compost dosage. Ngappa variety produced the highest dry grain yield per hectare with 3,834 kg/ha, while the highest average production of local Sulawesi aromatic rice was with the application of 16 tons per hectare of rice straw compost in this experiment which produced 4,241.78 kg of paddy per hectare.

Abstract

The scoop net, also known as Sodo', is a type of fishing gear commonly used by fishermen in the waters of Mallusetasi, Barru Regency. Unlike commercial fishing gear, the scoop net is an alternative method of fishing. This study aims to analyze the oceanographic parameters of the fishing area and the composition of the catch obtained using the scoop net in the Mallusetasi waters of Barru Regency. The research was conducted from May to September 2021, using survey methods such as observation, interviews, and documentation. Data on oceanographic parameters of the fishing area, catch composition, gear construction, and operational stages of the scoop net were collected and analyzed using descriptive methods. The findings were then tabulated to facilitate data interpretation. The results of the study showed that the oceanographic parameters in Mallusetasi waters, including temperature, salinity, current velocity, and depth, were suitable for operating the scoop net, particularly for targeting the primary catch of anchovies (Stolephorus Sp.) that can be caught at any time. However, the peak season for catching Medan anchovies (Stolephorus waitei) and Nasi anchovies (Stolephorus commersoni) occurs during the eastern season, specifically in July to August. As for the rebon shrimp (Acetes sp.), the catching season occurs in May.

Abstract

This study aims to determine the level of community satisfaction with the SIBANCEH toll compensation in Capa Paloh Village, Padang Tiji District, Pidie Regency. This study was conducted in March 2022. There were 42 samples from a population of 129 toll road compensation recipients in Capa Paloh Village, Padang Tiji District, Pidie Regency. Collecting data using questionnaires, interviews, and documentation. The method used is qualitative and descriptive analysis. Descriptive analysis technique, namely a technique for describing or explaining data related to the discussion, where this technique describes the toll compensation that occurred in Capa Paloh Village, Padang Tiji District. The results showed that the level of community satisfaction with the SIBANCEH toll compensation in Capa Paloh Village, Padang Tiji District, Pidie Regency was satisfied, because the people who used to have inadequate houses, with the payment of toll compensation, the houses have been renovated and after with the construction of the toll road, the area where they live is increasingly crowded and the population is growing. In addition, the people affected by land acquisition can use the compensation money recipients not only to buy houses or rice fields, but can also be used for business capital or the community's personal savings.

Abstract

This study aims to examine the efficacy of S. agalactiae whole cell vaccine orally with Artemia sp as a vaccine vector for prevention against Streptococcosis in tilapia. Fish fry used in the study were 2-3 cm in size that did not carry S. agalactiae bacteria, kept in 3 l volume jars as many as ten heads / jars. Giving the vaccine to fish orally by first soaking the vaccine into Artemia sp.. The length of soaking time of the vaccine is 15, 30, 60, 90, 120 and 150 minutes. The parameters observed were relative percent survival (RPS), antibody titer value, total leukocytes, pagocytic index, and leukocyte differential. The results of the RPS value study showed that the treatment between vaccines was not significantly different, while the treatment of vaccines with controls was significantly different (P<0.05). The highest RPS value was obtained in vaccine immersion treatment in Artemia sp. for 30 minutes and 120 minutes with a value of 93.33%. Furthermore, RPS is 86.67% at 15 and 150 minutes soaking and RPS is 80% at 30 minutes immersion. This shows that the level of vaccine protection against streptococcosis in tilapia fry is very high

Abstract

The aim of this study was to obtain the best color formulation of aromatherapy candles using grapefruit oil with patchouli essential oil fixative and to analyze the business feasibility of grapefruit aromatherapy candles. This research was conducted from June to August 2021 in the quality testing laboratory for the Agroindustry study program, Pangkep State Agricultural Polytechnic. This research was conducted using an experimental method with two stages, namely; first, making aromatherapy candles which aims to get the best color concentration in aromatherapy candles with a hedonic test, after the hedonic test with the best color will proceed to further research, namely the stage of selecting the aromatherapy candle aroma of grapefruit essential oil as a binder added with patchouli oil. Business continuity analysis is carried out by looking for investment costs, variable costs, profits, production Break Even Point (BEP), price Break Even Point (BEP), Benefit Cost Ratio (BCR), and pay back period. The results showed that the best color formulation of aromatherapy candles was in the A3 treatment with a color concentration of 1.5% with an average of 3.6. The best aromatherapy candle formulation was in treatment B3 with a concentration of 2.5% grapefruit oil and 0.25% patchouli oil fixative with an average hedonic test result of 4.36. The best formulation of the effect of aromatherapy candles was in treatment B3 with a concentration of 2.5% grapefruit oil and 0.25% patchouli oil fixative with an average organoleptic test result of 6.52 and 80% of the panelists felt relaxed, comfortable, fresh and somewhat refreshed. The results of the Benefit Cost Ratio (BCR) calculation analysis in the aromatherapy business with a BCR value of 1.11 indicate that this business is feasible to develop.

Abstract

The objective of this research was to estimate and analyze the availability of Angel fish (Pomacanthus sp.) based on the coral diversity conditions in the Spermonde waters of Pangkep Regency, South Sulawesi. The research method was based on parallel sampling of fish abundance (visual census) and coral cover percentage (Point Intercept Transect) at the study sites, namely Liukang Tumppabiring and Liukang Tangaya waters. The results showed that Liukang Tuppabiring had a fish abundance of 0.00005 individuals per square meter with a standing stock of 138 individuals, while Liukang Tangaya had a fish abundance of 0.005 individuals per square meter with a standing stock of 35,121 individuals. The abundance of Angel fish did not correlate positively with live coral cover, but its presence was influenced by the structural growth forms of the coral, namely branching, submassive, and massive coral in crevices. The production status of Angel fish in the Spermonde waters has exceeded the maximum sustainable yield (MSY). Therefore, additional fishing efforts would decrease the production of Angel fish. This indicates that the Angel fish has been overfished, which can affect its supply. In addition, the inverted curved supply curve indicates a decreasing supply, even with increasing fish prices, as it is suspected that the stock is decreasing.
