Abstract

This study aimed to examine the content of macronutrients (Nitrogen, Phosphorus, Potassium) and pH values in maggot manure fertilizer produced from the bioconversion of chicken excreta, and to compare it with commercial compost fertilizer available in the market. The research was conducted experimentally in the laboratory using two treatments: maggot manure fertilizer (P1) and commercial compost fertilizer (P2), with five replicates for each. Parameters analyzed included pH, nitrogen content (Kjeldahl method), phosphorus and potassium (wet ashing method), and total nutrient content, obtained by summing the N, P, and K levels. Data was analyzed descriptively and a significant difference was tested using an Independent Sample T-test. The results showed that pH values did not differ significantly between P1 and P2, indicating relatively similar soil pH stability from both types of fertilizer. However, maggot manure fertilizer (P1) had a significantly higher phosphorus content compared to commercial fertilizer (P2), demonstrating P1's great potential for root development and flowering. On the other hand, commercial compost fertilizer (P2) was significantly superior in nitrogen and potassium content, as well as overall total nutrient content, compared to P1. This aligns with the characteristics of chemical fertilizers, which are designed to deliver precise and high doses of macronutrients. Although the total nutrient content of P1 was lower, its 4.40% total nutrient content met the minimum requirement of Permentan No.1 Year 2019 (>2% NPK). In conclusion, commercial fertilizer excelled in the consistency and quantity of N and K, as well as total nutrients, while maggot manure fertilizer stood out in phosphorus content. The choice of fertilizer should be tailored to specific plant needs and soil conditions, making maggot manure fertilizer a potential good alternative or supplement, especially for increasing phosphorus availability by utilizing livestock waste.

Abstract

This study aimed to determine the effect of rosemary addition on the quality of pasteurized goat milk. The materials used in the study were Peranakan Etawa goat milk, rosemary, water, and sugar. A Completely Randomized Design was used, consisting of four treatments and five replications. The treatments included: P0 = pasteurized milk without rosemary (control), P1 = pasteurized milk with 1.5 g of rosemary in 50 ml solution, P2 = pasteurized milk with 3 g of rosemary in 50 ml solution, and P3 = pasteurized milk with 4.5 g of rosemary in 50 ml solution. Data were analyzed using analysis of variance (ANOVA). The results showed that the addition of rosemary significantly affected the organoleptic quality and hedonic test outcomes, which were conducted at the University of Boyolali. Organoleptic testing revealed a highly significant effect (P<0.01) on taste, aroma, and color. The hedonic test also showed a significant effect (P<0.01) on panelists' preference for milk with rosemary addition. The Total Plate Count (TPC) test indicated that rosemary extract significantly (P<0.01) reduced the number of bacteria in pasteurized milk. In conclusion, rosemary addition influenced the organoleptic quality of pasteurized goat milk in terms of taste and aroma, although it had no effect on color. The hedonic test results indicated that rosemary-added milk was less preferred in terms of taste, aroma, and texture, although the aroma was still acceptable to panelists. Furthermore, increasing the concentration of rosemary resulted in a greater reduction in bacterial count in pasteurized milk.

Abstract

This study aimed to evaluate the effect of cage floor height on broiler chicken performance in a closed house cage system. The parameters observed included feed consumption, body weight gain, Feed Conversion Ratio (FCR), performance index (IP), and mortality. The study used a Completely Randomized Design (CRD) with three treatments (0 m, 2 m, and 4 m floor) and six replications, where each replication consisted of 15 CP Charoen Phokpan strain broiler chickens. The results showed that cage height had a significant effect (P <0.05) on included feed consumption, body weight gain, Feed Conversion Ratio (FCR), performance index (IP), and mortality. A height of 4 m gave the best results with efficient feed consumption (49.92 g), the highest body weight gain (1.62 kg), the lowest FCR (1.65), the highest IP (292.23), and the lowest mortality (3%). Microenvironmental conditions such as temperature and humidity on the upper floor were more stable and supported the thermal comfort of the chickens, thus increasing growth efficiency. Thus, it can be concluded that the height of the cage is an important factor in the management of broiler chicken maintenance in the closed house system.

Abstract

Fermented lime waste has potential as a feed additive for poultry, but its utilization is hindered by its high pectin fiber content, which can negatively impact poultry performance. This study aimed to evaluate the effect of Aspergillus niger fermentation on pectin fiber content and the pH value of lime waste. The materials used were lime peel flour and a commercial Aspergillus niger mold. The study followed a completely randomized design (CRD) with four levels of A. niger starter: 0%, 1%, 2%, and 3%. Each treatment was replicated five times. The fermentation process was conducted under aerobic conditions for five days at room temperature. The results showed that fermentation with A. niger significantly increased the pH value of the fermented lime peel flour (P < 0.05) and decreased its pectin fiber content (P < 0.05).

Abstract

This study aims to determine the effect of organic fertilizer bio-selurry processed using Effective Microorganisms 4 (EM4) and MA-11 on the growth of odot grass (Pennisetum purpureum cv. Mott) intercropped with legume Indigofera zollingeriana. The study was conducted from January to March 2025 in Ampel District, Boyolali Regency. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and 5 replications, namely P0 (bio-selurry without addition), P1 (bio-selurry + EM4), P2 (bio-selurry + MA-11), and P3 (bio-selurry + EM4 + MA-11). The parameters observed included the time of first shoot emergence, number of shoots, number of leaves, leaf blade length, stem diameter, fresh forage production, and dry matter. The results showed that the treatment of bio-selurry fertilizer had no significant effect (P>0.05) on the first shoot, number of shoots, number of leaves, leaf length, stem diameter, and dry matter. However, there was a significant effect (P<0.05) on the production of fresh greens, with the highest results obtained in treatments P2 and P3. This indicates that the use of bio-selurry fertilizer fermented with EM4 and MA-11 can increase the production of odot grass greens, although it has not significantly affected other growth parameters in the early phase.

Abstract

The use of natural feed such as immunostimulants and alternative protein sources has been proven to efficiently improve poultry performance. This study examined the effect of Klanceng honey in the starter phase and Black Soldier Fly (BSF) maggot meal in feed on the productivity of local quail (Coturnix coturnix japonica). The study was conducted in Boyolali on December 24, 2024–February 9, 2025, using a Completely Randomized Design (CRD) with 4 treatments and 5 replications, involving 100 female quail. The treatments consisted of control (T0) and the addition of 5% (T1), 10% (T2), and 15% (T3) maggot meal, as well as 1% klanceng honey through drinking water in the starter phase. Maintenance was carried out from 1 day to 48 days of age. The parameters observed included feed consumption, PBB, FCR, SGR, egg-laying age, and mortality. Data were analyzed using ANOVA and Duncan's test (? = 5%). The results showed that the treatments significantly affected almost all parameters, except mortality. Treatment T3 gave the best results. It was concluded that klanceng honey and maggot meal were effective as functional feed to increase quail productivity. The results showed that administration in the P2 treatment significantly impacted quail productivity. The combination of klanceng honey and maggot meal was effective as a functional feed to improve the performance and efficiency of quail farming sustainably.
