Abstract

This study was undertaken to learn how the kitchen management at Ascent Premiere Hotel Malang attempts to improve the level of cleanliness and sanitation. The study method employed is a qualitative descriptive approach, with data collected through observation, interviews, and recording. The research subjects are sous chefs and junior sous chefs who can supply research-related information. The goal of this study is to focus on efforts to improve kitchen cleanliness and sanitation in order to provide a sense of security, comfort, and job efficiency for all staff members. According to the study's findings, several employees expressed dissatisfaction with the maximum execution of hygiene and sanitation requirements due to the low quality of the standard operating procedures (SOP) that were implemented. To address these problems, the cooks took immediate action by expanding the number of personnel, holding daily briefings before work, and doing other things that can help improve the hygiene and sanitation at the Ascent Premiere Hotel Malang kitchen.

Abstract

The purpose of this study is to convert tofu wastewater into biogas using an anaerobic digester with varying cow dung mixtures (10%, 15%, and 20%). The study method entails creating digesters including independent, dependent, and controlled variables. Variations in pH, temperature, biogas pressure, and biogas volume were detected throughout the course of a 15-day fermentation. The data show that in the 10% fluctuation, the greatest pH was on day 7 (7), whereas the highest temperature was 32°C on days 6 and 7. Biogas pressure emerged on day 6 (89.2 cmHg), resulting in a volume of 90 liters by day 15. In the 15% variation, the highest pH (7.2) occurred on day 8, with the highest temperature (34°C) on days 9 and 10. Biogas pressure began on day 5 (89.9 cmHg), with a biogas volume of 95 liters on day 15. The 20% variance resulted in the highest pH (7.4) on day 8 and the highest temperature of 35°C from days 9-11. Biogas pressure began on day 5 (90.7 cmHg), resulting in a biogas volume of 100 liters on day 15. This study sheds light on how to manage tofu waste into biogas with varying degrees of effectiveness and efficiency.

Abstract

Indonesia is a tropical country with entrepreneurs engaged in maize cultivation, most of whom live in rural areas. The corn processing process is heavily reliant on sunshine, however owing to the unpredictable environment and sunlight, which is less effective and hygienic in carrying out the corn drying process, the operation is hampered. As a result, a drying cabinet is created that uses heat from electricity and is specifically intended to accelerate the drying process. This corn drying rack employs incandescent lamps, including bulbs and holagen lamps. In addition, the number of drying racks is identified in order to assess the drying cabinet's capacity for work. After testing the tool with various blower speeds (15,000, 10,000, and 5,000 RPM), the electrical power utilized is 120 watts, which includes 50 watts of bulb/halogen lamp power, 40 watts of heated glass, and 30 watts of blower power. So it is known that holagen incandescent lamps are more successful at distributing work evenly on the shelf within 30 minutes, which can save drying time by 20% to 30%.

Abstract

In general, tablets are solid dose forms containing therapeutic substances, with or without fillers. Tablet compression is achieved by applying high pressure on powder (bulk) granules through a steel mold. The core tablet to be coated must meet certain standards because it will be moved and slammed repeatedly throughout the coating process. The extended fin is an additional fin that functions when the product is inserted into the coating pan and rotated, preventing the product from coming into direct contact with the coating pan wall during the coating process, resulting in friction and reactions that occur during the film coating process. For this reason, an expanded fin is inserted to reduce friction between the product and the pan coating machine's wall. The addition of the extended fin decreases friction between the drug and the machine wall, preventing the product coating process from reacting due to excessive friction with the machine wall. Additionally, the results of smoothness, glossiness, and color solidity are excellent. This resolves the issues that have previously lowered the proportion of production output.

Abstract

The metabolized substance was produced in the laboratory (postbiotics), according to three successive stages. The first stage included: isolating and identifying lactic acid bacteria from the ileum area in the small intestine of poultry, while the second stage included: activating the isolated bacteria on sterilized sorted milk media for three consecutive times. The third stage included: producing the biologically metabolized substance or biologically active compounds, in the form of a fine powder. This substance was added to the diets of broilers at a level of (0, 1, and 2) g /kg feed, for three experimental treatments, T0, T1, and T2, respectively, during the rearing period of 35 days. To study its effect on the productive traits and economic efficiency of broilers. The results of the statistical analysis showed: a significant improvement (P≤0.05) in the rates of body weight and weight gain, in addition to a significant improvement (P≤0.05) in the food conversion rate and in the economic efficiency measure in favor of the postbiotics T1 and T2 treatments compared to the control treatment. T0, while there are no significant differences in the rate of feed consumption between all the treatments studied.

Abstract

Cookies merupakan jenis biskuit dari adonan lunak, berkadar lemak tinggi, renyah, dan bila dipatahkan penampang potongannya bertekstur kurang padat. Pangan lokal seperti beras hitam dan kedelai hitam dapat diolah menjadi tepung yang kaya antioksidan sebagai substitusi tepung terigu. Tepung beras hitam dan tepung kedelai hitam mengandung antioksidan yang menjadi salah satu cara untuk mencegah risiko penyakit kronis. Tujuan penelitian ini adalah mengetahui pengaruh proporsi tepung beras hitam : tepung kedelai hitam dan penambahan minyak biji bunga matahari terhadap karakteristik cookies dan kemampuan aktivitas antioksidan pada cookies. Penelitian ini menggunakan desain rancangan acak lengkap (RAL) pola faktorial yang terdiri dari 2 faktor dengan 2 ulangan. Faktor I adalah proporsi tepung beras hitam : tepung kedelai hitam yang terdiri dari 3 level, yaitu 65%:35%, 75%:25%, dan 85%:15%. Faktor II adalah penambahan minyak biji bunga matahari yang terdiri dari 3 level yaitu 35%, 45%, dan 55%. Analisis data yang diperoleh menggunakan ANOVA pada taraf 5%. Jika ada perbedaan nyata dilanjutkan dengan Uji Duncan Multiple Range Test (DMRT) pada taraf 5%. Hasil penelitian menentukan bahwa perlakuan terbaik adalah pada proporsi tepung beras hitam : tepung kedelai hitam (85% : 15%) dengan penambahan minyak biji bunga matahari 55% merupakan cookies perlakuan terbaik dengan nilai kadar air 5,95%; kadar abu 1,02%; kadar lemak 12,41%; kadar protein 13,97%; kadar karbohidrat 57,31%.

Abstract

Penelitian ini bertujuan untuk mendeteksi keberadaan larva Soil Transmitted Helminths (STHs), khususnya hookworm, pada sampel tanah di Desa Manuntung, Kecamatan Kusan Hulu, Kabupaten Tanah Bumbu, Kalimantan Selatan. Wilayah ini dipilih berdasarkan kesamaan karakteristik geografis dan laporan prevalensi tinggi infeksi cacing di daerah sekitarnya. Desain penelitian ini adalah deskriptif dengan pendekatan observasional. Sebanyak 25 titik sampel tanah dikumpulkan dari dua lokasi berbeda, yaitu area persawahan (10 titik) dan area perkebunan kelapa sawit (15 titik). Sampel diambil pada kedalaman 3–5 cm dan diperiksa menggunakan metode Baermann di Laboratorium Mikrobiologi dan Parasitologi Universitas Borneo Lestari. Pemeriksaan difokuskan pada identifikasi larva hookworm berdasarkan morfologi mikroskopis, dengan analisis data disajikan secara deskriptif. Hasil penelitian menunjukkan bahwa seluruh sampel tanah dari persawahan (100%) dan sebagian besar dari perkebunan sawit (93,3%) positif mengandung larva hookworm. Karakteristik tanah yang gembur, berpasir, dan lembab di kedua lokasi tersebut diduga kuat mendukung pertumbuhan dan kelangsungan hidup larva. Metode Baermann terbukti efektif dalam mendeteksi larva STHs karena sensitivitas tinggi dan kemampuannya menangkap larva yang bergerak aktif di media cair. Kesimpulan dari penelitian ini menunjukkan adanya potensi tinggi penularan STHs kepada masyarakat sekitar, terutama kelompok yang bekerja di area pertanian dan perkebunan tanpa pelindung kaki. Hasil ini menjadi data awal penting untuk penelitian lanjutan pada manusia, serta mendukung perlunya intervensi berbasis perilaku dan sanitasi untuk menekan risiko infeksi kecacingan.
