Abstract

Beras analog yang disubtitusi glukomanan porang (Amorphophallus Oncophylus) mengandung serat yang tinggi dan memiliki indeks glikemk yang rendah (43) sehingga baik dikonsumsi oleh penderita diabetes. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian beras analog yang disubtitusi glukomanan porang terhadap kadar gula darah, berat badan, dan konsumsi ransum pada mencit yang diinduksi aloksan. Percobaan disusun dalam rancangan acak lengkap (RAL) terdiri dari 4 kali perlakuan dengan 6 ulangan. Data yang diperoleh diuji keseragamannya dengan menggunakan uji Bartlett dan kemenambahan data diuji dengan uji Tuckey. Selanjutnya data dianalisis dengan sidik ragam untuk mendapatkan penduga ragam galat dan mengetahui pengaruh perlakuan, kemudian data dianalisis dengan menggunakan uji BNT pada taraf 5%. Hasil penelitian menunjukan bahwa pemberian beras analog yang disubtitusi glukomanan porang pada mencit yang diinduksi aloksan memberikan kadar gula darah sebesar 93,83 mg/dL, menurunkan berat badan 3,53 g, konsumsi ransum 3,45 g/hari, dan efisiensi ransum -14,80%.

Abstract

This study is important because employee performance determines the success of government organizations. Declining performance due to low competence and a weakening organizational culture needs to be examined to provide an empirical basis for improving human resource management and the quality of public services. The objectives of this study are: 1) To determine the effect of competence on the performance of employees at the Education Department of South Sulawesi Province. 2) To determine the effect of organizational culture on the performance of employees at the Education Department of South Sulawesi Province. This study uses a quantitative method with an associative approach. The sample consists of the entire population, namely all employees of the Education Department of South Sulawesi Province, totaling 114 individuals. The results of this study indicate that competence has a positive and significant effect on employee performance. Therefore, efforts to enhance competence through training and professional development are crucial to improving employee performance at the Education Department of South Sulawesi Province. Organizational culture also has a positive and significant effect on employee performance. Hence, improving organizational culture through instilling positive values, enhancing communication, and developing a conducive work environment is essential to boost employee performance at the Education Department of South Sulawesi Province.

Abstract

Cookies merupakan jenis kue kering yang berukuran kecil, berbentuk datar, dan memiliki cita rasa manis karena diolah dengan cara dipanggang. Penelitian ini dilakukan untuk menentukan umur simpan cookies yang diformulasikan dengan penambahan tepung daun singkong, menggunakan metode Accelerated Shelf Life Testing (ASLT) berdasarkan model Arrhenius. Cookies dibuat dengan formulasi 94% tepung mocaf dan 6% tepung daun singkong, kemudian dikemas menggunakan plastik OPP dan aluminium foil. Produk disimpan pada suhu 25°C, 35°C, dan 45°C selama 30 hari. Pengamatan dilakukan terhadap perubahan kadar air, warna, dan asam lemak bebas. Parameter kritis yang digunakan dalam penentuan umur simpan adalah asam lemak bebas, karena berkaitan langsung dengan tingkat ketengikan produk. Hasil menunjukkan bahwa cookies mengalami peningkatan asam lemak bebas selama penyimpanan, dengan pola kinetika reaksi mengikuti orde nol. Umur simpan cookies pada suhu 25°C berdasarkan parameter asam lemak bebas adalah 154 hari untuk kemasan alumunium foil dan 141 hari untuk kemasan kemasan OPP. Hasil ini menunjukkan bahwa aluminium foil lebih efektif dalam mempertahankan kestabilan mutu produk selama penyimpanan. Oleh karena itu, pemilihan jenis kemasan dan suhu penyimpanan berperan penting dalam menjaga kualitas dan memperpanjang umur simpan cookies berbasis tepung daun singkong.

Abstract

Crystal guava is a fruit that can be processed into candied fruit. Calcium chloride (CaCl₂) is a food additive that functions as a firming agent and may affect the final quality of the candied guava. This study aimed to determine the effect of CaCl₂ concentration, soaking duration, and their interaction on the characteristics of candied crystal guava. A Completely Randomized Block Design (CRBD) was used with two factors and three replications. The first factor was CaCl₂ concentration: K1 (1%), K2 (3%), K3 (5%). The second factor was soaking duration: L1 (1 hours), L2 (2 hours), L3 (3 hours). The parameters observed included texture, moisture content, pH, sensory properties (texture, taste, and overall acceptance), and calcium content. Data were analyzed using Bartlett‟s and Tukey‟s tests, followed by ANOVA and HSD (Honestly Significant Difference) at a 5% significance level. The results showed that CaCl₂ concentration significantly affected pH and had a highly significant effect on moisture, texture, and sensory characteristics. Soaking duration had a highly significant effect on moisture, texture, and sensory properties, but not on pH. The interaction between both factors had a highly significant effect on sensory properties, but no significant effect on pH, moisture, or texture. The best treatment was 5% CaCl₂ with 3 hours of soaking (K3L3), resulting in a texture of 783.917 gf, moisture content of 79.83%, pH 4.21, texture score of 4.4 (crunchy), taste score of 4.12 (liked), overall acceptance of 4.46 (liked), and calcium content of 339.2 mg/kg.

Abstract

This study aims to analyze and test the influence of job placement, supervision, and the work environment on employee performance at the Makassar City Communication and Informatics Office. It is hypothesized that job placement, supervision, and the work environment each have a positive and significant effect on employee performance. This study employs a quantitative approach using a survey method. The population consists of all 97 employees of the Makassar City Communication and Informatics Office, with a saturated sampling technique applied, meaning the entire population is used as the sample. Data were collected through structured questionnaires distributed to respondents. The variables examined include job placement, supervision, and work environment as independent variables, and employee performance as the dependent variable. Data analysis was conducted using multiple linear regression analysis with the assistance of SPSS. The results indicate that job placement has a positive and significant effect on employee performance. Similarly, supervision shows a positive and significant influence on employee performance. The work environment also has a positive and significant effect on employee performance. These findings demonstrate that all three independent variables simultaneously and partially contribute to improving employee performance. The implications of this study suggest that organizations, particularly the Makassar City Communication and Informatics Office, should enhance human resource management practices by ensuring appropriate job placement, strengthening supervisory functions, and creating a conducive work environment. These efforts are expected to improve employee performance and ultimately enhance the quality of public services. Future research is recommended to include additional variables or broader organizational contexts to enrich the findings.
