Abstract

Particleboard is a composite wood that still relies on wood from natural forests. Research on the manufacture of particleboard using ligno-cellulosic fibrous material other than wood namely agricultural waste in the form of bagasse and corn stalks using urea-formaldehyde adhesive has been carried out, aiming to obtain information about the characteritic of the resulting particleboard. Particles from bagasse and corn stalks were dried in an oven to a moisture content of 5%. The particleboard density target was made 0.7 g/cm3, using liquid urea formaldehyde (UF) adhesive, with a pressurization process of 12 kg/cm2 at 140°C for 10 minutes. After being conditioned for 7 days, the particle board was made a test sample. The results showed that the particleboard made of bagasse and corn stalks had a density of 0.64 g/cm3 and 0.67 g/cm3, respectively, including medium density, so that they could be used for space insulation, furniture. The development of thickness, MOR and MOE of the manufactured particleboard is significantly influenced by the type of raw material. Moisture content, density and MOR of bagasse particle board are in accordance with SNI standards, while on corn stalk particle board are water content and density.

Abstract

Dewasa ini permintaan bibit ayam joper yang merupakan hasil persilangan ayam ras petelur final stock dengan ayam lokal jantan mengalami peningkatan terus dari tahun ke tahun. Ayam joper mempunyai banyak keunggulan yaitu pertumbuhannya yang lebih cepat dengan FCR maksimal diangka 3 pada akhir panen berat 1 kg, postur tubuh ayam lebih besar dari ayam kampung asli serta karakteristiknya tentang ketahanan penyakit dan pakan sederhana bisa berkembang, kualitas dagingnya mirip ayam kampung asli. Penelitian ini bertujuan mengetahui pengaruh dan level penambahan kecambah kacang hijau (Phaseolus radiatus) terhadap fertilitas, daya tetas, dan berat (Day Old Chick) DOC, hasil inseminasi buatan. Materi yang digunakan dalam penelitian ini adalah 45 ekor hyline – brown betina umur 30 minggu dan 3 ekor jantan lokal umur 1,5 tahun. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 3 ulangan. Perlakuan tersebut menguji P0 (tanpa pemberian kecambah kacang hijau) sebagai kontrol, P1 (30 gram kecambah kacang hijau) dan P2 (40 gram kecambah kacang hijau). Variabel yang diukur adalah fertilitas telur, daya tetas telur, dan berat DOC. Metode analisis data mengunakan ANOVA dan apabila terjadi perbedaan nyata selanjutnya akan diuji dengan uji jarak berganda Duncans. Hasil penelitian menunjukan bahwa penambahan kecambah kacang hijau berpengaruh nyata (P<0,05) terhadap fertilitas, daya tetas, dan berat DOC. Hasil uji lanjut Duncan menunjukkan adanya perbedaan di setiap perlakuan. P0 berbeda nyata dengan P1 yang memiliki fertilitas tertinggi. Sementara daya tetas dan berat DOC tertinggi pada perlakuan P2. Kesimpulan hasil penelitian ini adalah penambahan kecambah kacang hijau meningkatkan sebanyak 30 gram/ekor dua kali dalam seminggu, dengan umur perkecambahan kacang hijau 48 jam dapat ,meningkatkan fertilitas, daya tetas telur, dan berat DOC hasil inseminasi buatan.

Abstract

Village Owned Enterprises (BUMDES) are institutions established with the aim of improving the welfare of society through the development of productive economic enterprises and other sectors. Village Owned Enterprises (BUMDES) are growing over time with various new innovations that have been implemented to attract community interest. This study aims to determine the effect of product diversity, shopping experience, and service quality on consumers' repurchase decisions at BUMDES Krowe stores. The research method used is a quantitative method using primary data and secondary data. The data analysis method used is instrument test, multiple linear regression analysis, coefficient of determination, t test, and F test. The results show that: (1) product variety partially has a significant effect on repurchase decisions. This shows that the availability of a variety of products will increase repurchase decisions. (2) shopping experience partially has a significant effect on repurchase decisions. This shows that a good shopping experience will increase repurchase decisions. (3) service quality partially has a significant effect on repurchasing decisions. This shows that the existence of optimal service quality will increase repurchase decisions. (4) product variety, shopping experience, and service quality simultaneously affect repurchase decisions. These three variables have an important role in influencing repurchase decisions, where the availability of a variety of products, a good shopping experience, and optimal service quality will jointly influence repurchase decisions.

Abstract

Penelitian ini bertujuan untuk membandingkan aktivitas antioksidan, antibakteri, dan uji toksisitas dari berbagai jenis ekstrak kulit batang pohon kesambi (Schleichera oleosa (Lour)Oken). Tahapan penelitian meliputi proses esktraksi kulit batang kesambi dari kecamatan Mancak Serang dengan teknik maserasi bertingkat menggunakan 3 pelarut : Metanol, n-heksan, dan etil asetat. Ekstrak tersebut kemudian diuji aktivitas antioksidan, antibakteri, dan toksisitasnya. Hasil pengujian antioksidan dengan metode DPPH, antibakteri dengan metode difusi agar, dan uji toksisitas dengan metode BSLT didapat hasil penelitian menunjukkan bahwa ekstrak etil asetat memiliki aktivitas antioksidan (IC50 7,723 ppm) yang lebih baik dibandingkan dengan ekstrak metanol (IC50 7,801 ppm), dan ekstrak n-heksan (IC50 8,568 ppm). Aktivitas antibakteri menunjukkan adanya kemampuan untuk menghambat pertumbuhan bakteri Streptococcus aureus dibandingkan bakteri Escherichia coli pada konsentrasi 10000 ppm, dan hasil uji toksisitas menunjukkan bahwa ekstrak etil asetat memiliki aktivitas yang lebih baik (LC50 305,17 ppm) dibandingkan ekstrak n-heksan (LC50 374,96 ppm) dan ekstrak metanol (LC50 431,26 ppm).

Abstract

This study aims to determine the effect of social support, product knowledge, and consumer ethnocentrism on buying decisions for Ponorogo batik in East Java. This research is quantitative. The number of samples in this study was 250, the sampling method used purposive sampling. The data collection method uses questionnaires distributed to respondents online and offline, data measurement uses a Likert scale of 1 – 5, the method of analysis of this research is SEM (Structural Equation Modeling) with the help of tools IBM SPSS AMOS statistics 26. The results of this study found that social support and consumer ethnocentrism had a positive and significant effect on increasing buying decisions, while product knowledge in this study was found not to have a significant effect on buying decision of batik clothes in Ponorogo. These findings contribute to the development of a customer culture theory regarding ethnocentrism towards local products that can become a culture in people's behavior as a love for the local products they have. The novelty of this research is that product knowledge is not a guarantee for someone to want to make a purchase. This is because consumers do not have sufficient information about the product, which results in consumers having limited knowledge.

Abstract

Kadmium (Cd) dalam suatu perairan tergolong sebagai salah satu bahan pencemar pada air dan terkontaminasi ke dalam biota air. Logam berat Cd umumnya berasal dari limbah industri, pertanian, serta aktivitas manusia lainnya, seperti yang ditemukan di sekitar perairan tambak Mangunharjo, Semarang. Tujuan penelitian ini adalah untuk menguji kandungan Cd yang terdapat dalam sedimen dan air serta rajungan (Portunus pelagicus) yang ditangkap di perairan tambak Mangunharjo. Penelitian ini dilaksanakan pada bulan Desember 2020 - Januari 2021. Pengukuran konsentrasi Cd dilakukan dengan metode Atomic Absorption Spectrophotometer (AAS). Kontaminasi logam berat Cd dalam air terukur sebesar <0,001-0,395 mg/l yang telah melebihi baku mutu untuk biota laut. Konsentrasi Cd dalam sedimen dasar perairan dan rajungan diperoleh secara berurutan, yaitu <0,001 mg/kg dan 0,028-1,96 mg/kg. Faktor biokonsentrasi (BCF) didapatkan berkisar antara 60 – 1655 (Desember) dan 0,5 – 1014 (Januari), nilai tersebut termasuk kategori rendah hingga sangat tinggi. Konsentrasi Cd pada sampel rajungan diketahui telah melebih baku mutu yang ditetapkan dalam Peraturan BPOM No. 23 tahun 2017 yaitu maksimum 0,1 mg/kg. Perhitungan batas aman konsumsi rajungan yang telah terkontaminasi Cd dalam kasus ini yaitu 0,0065 kg daging/minggu untuk anak-anak dengan bobot 15 kg dan 0,21 kg daging/minggu untuk dewasa dengan bobot 50 kg. Parameter lingkungan perairan seperti suhu, pH, salinitas dan DO memiliki nilai yang bervariasi antar stasiun penelitian dan juga antar waktu penelitian. Rajungan dari perairan Mangunharjo sudah tercemar logam berat Cd, sehingga dibutuhkan upaya khusus agar tetap aman untuk dikonsumsi.
