Abstract

The purpose of the study was to test and analyze the response of chicken manure and NPK 16:16:16 application on the growth and yield of purple eggplant plants in sandy land. The study used a Randomized Bloc Design, consisting of two factors. The first treatment was the provision of 4 levels of chicken manure with doses of 0, 30, 35 and 40 t ha-1 while the second treatment of NPK 16:16:16 consisted of 3 levels, namely doses of 0, 300 and 350 kg ha-1. From the two treatment factors, 12 combinations were obtained. Each was repeated 3 times, so that there were 36 experimental units. The results showed that the response of chicken manure affected all growth variables, both plant height, stem diameter and number of productive branches at a dose of 30 t ha-1. While the dose of 40 t ha-1 affected the yield variable in the form of the number of fruits per plant with the largest number of 8 fruits per plant with the heaviest fruit weight of 223.89 g fruit-1. In addition, the dose response of NPK 16:16:16 also affects the yield variable in the form of the number of fruits per plant at a dose of 350 kg ha-1 with the largest number of fruits being 6 fruits per plant-1.

Abstract

Oil palm empty bunch and grass, are sorts of agricultural waste, that contribute to evolving gas emissions--methane (CH4) and carbon dioxide (CO2).  Therefore, agricultural waste management to compost is one system to minimize the gas emissions in oil palm plantations.  Generally, using bio-decomposer lignocellulolytic bacterium is the way to speed up the composting.  Bacillus brevis BRT-1 and Bacillus megaterium BTB-1, having potency as bio-decomposer agents, are members of cellulolytic bacteria origin of soil swamps tidal.  Adding cellulolytic bacteria indigenous into the composting of oil palm empty bunch and grass are the objectives in our studies to observe, i.e. C-organic changes patterns, methane, and carbon dioxide emissions.  Two inoculants of cellulolytic bacteria comprised of BRT-1 and BTB-1 isolates were applied to the two substrates in composting the agricultural waste by adding cow manure.  The parameters of analysis were observed during twenty days, in addition, C-organic substrates were measured by the Walkley and Black method.  Especially for methane and carbon dioxide were observed by Micro Gas Chromatography, meanwhile, the addition of two inoculants of cellulolytic bacteria had a significant impact on C-organic changes during the composting.  Otherwise, using cellulolytic bacteria in this study showed no significant effect of methane and carbon dioxide.  Moreover, the result is also some of the depicted parameters, particularly of C-organic contain undergone alleviate on oil palm empty bunch substrates of BTB-1 – KS treatments.  Besides that, the C-organic content of grass substrates also decreased in BTB-1 treatments, furthermore, the methane emissions for oil palm empty bunch underwent fewer BRT-1+KS treatments.  On the other sides, the methane emissions increased during observation in grass substrates of BRT-1+KS treatments.  The same cases for the carbon dioxide emissions in oil palm empty bunch substrates are also decreased in BRT-1 treatments.  Meanwhile, the carbon dioxide emission underwent the escalation of grass substrates in BRT-1+KS treatments.  The utilization of cellulolytic bacteria Indigenous has the potential as a bio-decomposer agent in composting especially in accelerating C-organic changes.

Abstract

Tuberculosis (TB) is an infectious disease that is currently still a serious health problem in society, both in terms of mortality rates, morbidity rates, diagnosis and its therapy rates. Sputum quality is an important component in laboratory examinations. The quality of sputum samples can affect the number of M. tuberculosis bacteria. This study aims to determine the differences in the morphological characteristics of M. tuberculosis bacteria with the length of time of delay in sputum sample examination. The study was conducted at the Klinik Utama Kesehatan Paru Masyarakat Purwokerto. The study used a descriptive method with a cross-sectional design. The sample population of this study were all suspected TB patients who underwent Molecular Rapid Technique (MRT) examinations at the Klinik Utama Kesehatan Paru Masyarakat Purwokerto (KKPM) in the January-June 2024. The research sampling technique was purposive sampling that met the inclusion criteria. The results of the study showed that the morphological characteristics of the M. tuberculosis bacteria vary in each sputum sample, based on differences in the quality of the sputum examined with a general description of the morphological characteristics of the bacteria, which have the form of monobacillus, diplobacillus and bacillus, solitary and in colonies, and are a type of Gram-positive bacteria.  Keywords: Mycobacterium tuberculosis, MDR-TB.

Abstract

Jajanan siomay merupakan salah satu makanan yang banyak diminati oleh masyarakat dan dijual bebas di pasar tradisional. Bahan makanan mudah tercemar oleh golongan bakteri Coliform adalah bahan makanan tradisional dengan pengolahan sederhana. Jajanan siomay rentan terkontaminasi oleh berbagai bakteri patogen akibat kurangnya penerapan higiene dan sanitasi penjamah makanan. Penelitian ini mengidentifikasi keberadaan bakteri Colifom pada produk industri rumah tangga siomay di Kecamatan Purwokerto Selatan. Penelitian ini merupakan penelitian observasional laboratorik dengan teknik standar pemeriksaan mikrobiologi makanan dan minuman menggunakan metode kuantitatif yaitu Most Probable Number (MPN) dan Membran Filter. Teknik pengambilan sampel penelitian adalah purposive random sampling. Variabel yang diamati adalah analisis bakteri Coliform pada siomay, air yang digunakan dalam proses pembuatan siomay dan higiene sanitasi tempat pembuatan siomay dengan melakukan wawancara pengisian kusioner di Kecamatan Purwokerto Selatan. Hasil yang diperoleh menunjukkan 8 dari 12 sampel siomay terkonfirmasi mengalami kontaminasi golongan bakteri Coliform. Pemeriksaan air PDAM yang digunakan dalam pengolahan siomay didapatkan hasil 0/100 mL yaitu memenuhi syarat berdasarkan Peraturan Menteri Kesehatan Nomor 2 Tahun 2023. Higiene sanitasi penjamah makanan menunjukkan bahwa pengetahuan dan sikap penjamah makanan pada pedagang siomay di kelurahan Berkoh dan di kelurahan Purwokerto kidul dari rekapitulasi rata-rata memiliki kategori pengetahuan dan sikap baik.
