Abstract

Penelitian ini didasarkan pada upaya pemanfaatan limbah sampah kota yang keberadaannya melimpah dan mencemari lingkungan agar dapat dimanfaatkan menjadi suatu produk yang memiliki nilai ekonomis tinggi yaitu kompos, selain itu juga dapat menjadi solusi dalam mengatasi masalah kelangkaan serta mahalnya harga pupuk saat ini. Penelitian ini dilaksanakan di kampus Politeknik Pertanian Negeri Samarinda, dengan lamanya waktu penelitian adalah 3 bulan terhitung mulai bulan Juli sampai dengan Oktober 2020 yang meliputi: persiapan alat dan bahan, pembuatan kompos, pengambilan data dan analisis kompos. Tujuan penelitian yaitu mengetahui lama waktu pembuatan kompos hingga kompos dikatakan jadi, dan mengetahui kualitas kompos berdasarkan standar SNI 19-7030-2004. Hasil penelitian menunjukkan bahwa; kompos jadi pada hari ke-19 yang ditandai dengan warna kompos coklat kehitaman, tidak berbau, bentuk/tekstur remah dan suhunya sudah stabil mendekati suhu ruang dan kompos yang dihasilkan jika dibandingkan dengan standar SNI 19-7030-2004 untuk C organik, N dan K memenuhi standar sedangkan pH H2O, C/N rasio dan P belum memenuhi standar SNI 19-7030-2004.

Abstract

Available Indonesian dependency parsers can be considered worse than other languages’ parsers that have been researched thoroughly. Currently, Indonesia dependency parsers can’t reliably parse sentences with gerund(s) and/or ellipsis correctly. This is because of the sparse feature representation that causes difficulty in parsing these types of sentences. In this research, dense representation is proposed for Indonesian dependency parser. The use of dense word representation may allow better generalization and gives more information regarding the words to be parsed, which allows a more accurate parsing. The scope of the dependency parsing in this research is limited to well-formed Indonesian sentences, using the local transition-based parsing. Based on our experiments, we found that using word embedding instead of sparse word representation increases parsing accuracy significantly.

Abstract

The propolis produced by honeybees as it is used a material for cosmetic and health industry fiberglass-constructed has high economy value. However, the effective methode for the propolis production has not been found. The objective of this research was to find out the effectiveness of four propolis traps variations on the propolis production of Apis mellifera honeybees. Materials used in this research were sixteen colony of Apis mellifera honeybees and propolis traps. The propolis production and the formed surface area on traps were collected from four trap treatments with four replications. The obtained data were analyzed by using Completely Random Design Analysis and Tukey Test. The most effective of propolis traps was that made of fiberglasses with hole direction same as frame direction (the average production of 2.03 g). The largest of propolis surface area was produced by propolis trap with hole direction same as frame direction (28.29 cm2). No corellation between the large of propolis survace (cm2) and propolis production (g) was observed. Keywords: honeybees, propolis traps, propolis production.

Abstract

This paper investigates the influence of company characteristic toward Corporate Social Responsibility disclosure. The research is using the proxy of management ownership, leverage, size, profitability and company profile as the variable of company characteristic, while the CSR disclosure, unlike the previous researches, is proxied by dummy score from the companies’ mandatory disclosure based on the items of Public Environmental Reporting Initiative (PERI) and Global Reporting Initiative Social Performance (GRISP) issued by Global Reporting Initiative (GRI). Our research found that simultaneously, company characteristics significantly influence CSR disclosure. Whereas based on the partial test, amongst the characteristics observed, only company profile which significantly influences CSR disclosure. The result indicates that legitimacy from the society is the big concern of companies and therefore drives the actions of companies. However, the disclosure presumably depends on the awareness of the management toward social and environmental prosperity because the pressure from investors and market is still weak. Keywords: Corporate Social Responsibility, management ownership, leverage, size, profitability, company profile

Abstract

Penelitian ini bertujuan untuk menguji hubungan antara partisipasi anggaran dan kinerja  manajerial  yang  dimoderasi  oleh  persepsi  budaya  organisasi  (persepsi  manajer terhadap inovasi dan persepsi manajer terhadap detail). Dalam penelitian ini, 90 sampel manajer  menengah  diperoleh  dari  perusahaan  manufaktur  yang  di  analisis  dengan menggunakan analisis regresi berganda. Empat variabel yang diukur meliputi partisipasi anggaran, persepsi manajer terhadap inovasi, persepsi manajer terhadap detail, dan kinerja manajerial.   Hasil  penelitian  menunjukkan  peningkatan  partisipasi  anggaran  mengakibatkan peningkatan  kinerja  manajerial  bagi  manajer  yang  mempunyai  nilai  inovasi  tinggi  dan manajer  yang  memiliki  persepsi  terhadap  detail.  Ketika  manajer  memiliki  nilai  inovasi rendah, persepsi terhadap detail tinggi, bagaimanapun mempunyai pengaruh yang signifikan terhadap hubungan antara partisipasi anggaran dan kinerja manajerial, namun demikian hubungan tersebut cukup lemah.  Kata Kunci: Partisipasi anggaran, inovasi, attention to detail, kinerja manajerial

Abstract

Sand of Pulau Bungin is a natural sand that comes from Batang Kuantan River, Kuantan Singingi Regency. The existence of sand of Pulau Bungin makes development progress in Kuantan Singingi Regency because easily obtained, and more economical no need to bring sand material from other area and not have to go through stone breaking process by stone crusher. Based on the Bina Marga Specification 2010 Revision 3, the use of natural sand for asphalt concrete mixture (AC) should not exceed 15% of the total aggregate mixture weight. Therefore, we need to know the efficiency of using natural sand in concrete asphalt mixture (AC) for optimal utilization. This research aims to find out the optimum asphalt (KAO) and to know Marshall's characteristics whether to meet the Bina Marga Specification 2010 Revision 3. The natural fine aggregate variation of sand used in this research is 0%, 5%, 10%, 15% and 16 % of the total weight of the aggregate mixture. The addition of natural sand in the asphalt concrete mixture of the asphalt concrete base (AC-Base) causes the value of optimum asphalt (KAO) to decrease. On the mixture asphalt concrete base (AC-Base), 5% of the sand content of the 5% content of the optimum asphalt content (KAO) was increased by 6,20% and the largest stability was 3341 kg. Without considering the limits of natural sand usage as set out in the Bina Marga Specification 2010 Revision 3 then the addition of natural sand is still possible in the asphalt concrete base (AC-Base) until 16%.Keywords: Natural sand, asphalt concrete base (AC-Base), a general Specification Bina Marga 2010 Revision 3 and characteristics of Marshall.
