Abstract

The development of industrial food products that are growing rapidly and are ready-to-eat, make people increasingly fond of complementary food products, namely sauces and soy sauce. Even the food consumed is of particular concern because it causes many losses, such as patients who are poisoned or whose digestion is disrupted due to the food being consumed has been contaminated by materials or microorganisms. This study aims to determine the bacterial content of various brands of soy sauce and tomato sauce in Masomba market, Palu City. The method used in this research is descriptive research using an observational approach where in practice this study aims to determine the presence or absence of bacteria in soy sauce and tomato sauce of various brands in Masomba Palu market. Based on the results of research conducted on ten samples of soy sauce and tomato sauce sold at the Masomba market in Palu which was carried out at the Environmental Health Laboratory of Poltekkes, the Ministry of Health, Palu, it was found that one positive sample contained Eschercia coli and Staphlococcus bacteria, namely the soy sauce sample E with MPN number 43, and Staphlococcus. aureus with 12 colonies. This study suggests that soy sauce producers should increase the selection of good raw materials and improve the sanitation of soy sauce making. For the community, it is expected to be more careful in choosing the soy sauce snacks that will be consumed. For further researchers, it is hoped that they will be able to examine other pathogenic bacteria and check the content of other food additives contained in soy sauce such as preservatives, thickeners.

Abstract

Biji labu kuning (Cucurbita moschata) dalam kehidupan sehari-hari dimanfaatkan hanya sebatas kuaci biji labu, Padahal biji labu kuning dapat diolah dalam berbagai bentuk olahan. Salah satunya yaitu dalam bentuk olahan tempe biji labu kuning. Tempe merupakan makanan tradisional hasil fermentasi Rhizopus sp. yang dibuat dengan cara fermentasi atau peragian, dan dapat dijadikan sebagai sumber pangan yang memiliki nilai ekonomis serta merupakan sumber protein tinggi. Penelitian ini bertujuan untuk menentukan kadar protein pada tempe biji labu kuning dan pemanfaatannya sebagai media pembelajaran. Penelitian yang dilakukan merupakan jenis penelitian deskriptif eksploratif. Tempe biji labu kuning dianalisis kadar proteinnya dengan menggunakan analisis Kjedhal mikro melalui tiga tahapan yaitu destruksi, destilasi dan titrasi sebanyak tiga kali pengulangan. Hasil penelitian menunjukkan nilai rata-rata kadar protein tempe biji labu kuning yaitu sebesar 24,66%. Berdasarkan hasil uji validasi oleh tim ahli ahli isi, desain dan media serta 20 mahasiswa, hasil penelitian sangat layak dimanfaatkan sebagai media pembelajaran berupa poster dengan persentase kelayakan sebesar 81,49%.

Abstract

Semi-enclosed waters surrounded by islands such as Balikpapan Bay, whose waters are influenced by the dynamics of sea tides which affect current speed. Therefore, to understand the pattern and circulation of ocean currents in Balikpapan Bay, especially in the Wain River shipping channel, one way is by hydrodynamic modeling. The water area on the Wain River is an area related to shipping lanes as a shipping route at the Ferry Port. This research on current speed and direction aims to further research on maintaining the depth of shipping lanes due to sedimentation around the Ferry Harbor waters. Therefore, researchers conducted an initial study to create a simulation model of tidal current patterns using Mike 21 software with the aim of finding out what the tidal current patterns and current directions are in the waters of Balikpapan Bay as further data for maintaining the depth of shipping lanes. The data processing used is based on primary data in the form of current speed and direction, and tides and secondary data in the form of depth, current speed and direction, and tides, which are then validated using the RMSE method and to determine the type of tide using the Almilarty method. The results of this research are modeling tidal flow patterns and mapping changes in the morphology of the Wain River. The current speed at high tide ranges from 0.1 m/s to 0.4 m/s, while the current speed at low tide ranges from 0.1 m/s to 0.2 m/s. The depth of the waters around the Wain River is 1 m to 5 m. The tidal type in the waters of the Wain River is a mixed daily double bias.

Abstract

Unstable cash flows remain a critical constraint on growth and earnings in many micro, small, and medium enterprises (MSMEs), especially in fast moving retail segments. This study examines how cash management strategies shape profitability performance in Liga Store ID Makassar, an MSME retail fashion business in Indonesia. The study objectives are to (1) identify the enterprise’s cash management practices, (2) analyze how those practices support liquidity discipline, and (3) interpret their relationship with profitability indicators. A qualitative descriptive design was used. Purposive sampling targeted key financial actors (owner and administrative finance staff). Data were obtained through in depth, semi structured interviews and corroborated with internal financial documents (cash logs, expense records, profit reports). Descriptive references to Return on Assets (ROA) and Return on Equity (ROE) informed interpretation of profitability tendencies. Results indicate that Liga Store ID applies an integrated, low cost cash control bundle: strict petty cash limits, daily Excel based transaction recording, routine monthly cash flow planning, early payment discount capture from suppliers, and spending caps linked to projected inflows. These practices help preserve liquidity, reduce leakage, and support margin improvement—as reflected in observed movements in profitability ratios across review periods. Ongoing constraints include limited digital accounting capability, uneven financial literacy, and customer payment timing gaps that sustain cash flow volatility. The study extends MSME finance literature by demonstrating that context appropriate cash management bundles can reinforce financial resilience and profitability in small retail enterprises, and offers practical guidance for upgrading cash budgeting discipline and digital recordkeeping in similar settings.
