Abstract

Sebagai bahan bakar utama pada proses pembuatan gula tebu merah, sisa ampas tebu perlu disimpan untuk cadangan bahan bakar pada musim giling berikutnya. Namun ternyata untuk melakukannya tidak mudah. Ampas tebu yang telah kering mempunyai sifat-sifat fisik yang kaku, keras dan mengembang seperti kapuk. Secara kuantitas jumlahnya sedikit tetapi dengan volume yang besar sekali sehingga menyulitkan saat menanganinya. Penelitian ini dimaksudkan untuk merancang secara ergonomis sebuah alat bantu kerja berupa mesin pres ampas tebu. Dengan menggunakan anket peta tubuh Nordic dan pengukuran tingkat kelelahan, akhirnya diperoleh sebuah alat bantu kerja berbentuk mesin pres hidraulik yang secara ergonomis telah terbukti dapat digunakan secara aman, nyaman dan tidak menimbulkan rasa sakit bagi penggunanya (tingkat kelelahan hanya 12.2%). Dari aspek produktivitas, maka dengan mesin pres ini mampu meningkatkan produktivitas kerja penanganan ampas sebesar 55.6% lebih besar dibanding saat sebelum menggunakan mesin press dan mampu menyusutkan volume hingga tinggal 39.7%.kata kunci : pengrajin gula tebu merah, ampas tebu, mesin pres

Abstract

Cairan yang terkandung dalam batang galing-galing (Cayratia trifolia) memiliki kandungan anti bakteri, anti oksidan, anti virus untuk menjaga luka, yang membantu mengatasi infeksi pada luka, dapat mengurangi nyeri serta meningkatkan sirkulasi darah yang memberi kontribusi pada proses penyembuhan. Cairan galing-galing juga merangsang tumbuhnya jaringan baru, sehingga mengurangi timbulnya parut atau bekas luka pada kulit. Diharapkan cairan galing-galing dapat menyembuhkan luka bagi para penderita diabetes.  Tujuan penelitian ini untuk mendapatkan karakteristik kadar gula dalam darah sebelum dan setelah dilakukan terapi cairan galing-galing terhadap penyembuhan luka diabetes. Desain penelitian menggunakan pra eksperimental dengan pendekatan one-group pre-post test. Populasi penelitian adalah pasien yang menderita luka diabetes di Kelurahan dr. Sutomo, Kecamatan Tegalsari Surabaya, sampel diambil di RW 05 Kelurahan dr. Sutomo, Kecamatan Tegalsari Surabaya dengan menggunakan teknik non probability sampling dengan pendekatan purposive sampling. Setelah dilakukan pengukuran kandungan gula dalam darah sebelum dan sesudah dilakukan terapi cairan galing-galing, serta diuji dengan Uji Rank Wilcoxon didapatkan bahwa terapi cairan galing-galing memang dapat menurunkan kandungan gula dalam darah bagi pasien diabetes.

Abstract

Fish and lobster embankment was main occupation of most of Lamongan regency people. So farthey always used fabricated pellet as a fish and lobster food. And this food supplied by broker.There was a dependency between people and broker. This dependency caused problem, thatwas, broker could rise up the price of pellet whenever he wanted. At the other side, the use offabricated pellet in long time will made embankment media in satiation condition. Thiscondition will made many fishes and lobsters died in growth period and the death up to 40%.Gapoktan was a group of people who explored and invented the alternative fish and lobsterfood. This alternative food was made of natural raw material so it reduced the death until 20%.With this alternative food they wanted to be independent in fish and lobster food procurement.They wanted have alternative pellet. But they didn’t have sciences and technologies to make it.This research was designed to overcome their problem. Designing the extruder machine was theanswer of their problem. Designing was done based on the ergonomic concepts. Finally, wasknown this machine capacity up to 672 kg/day. It means that the machine could fulfill theminimum need of fish and lobster food. There were two variance of diameter of pellet, that wasfive and three millimeters with five until ten millimeter long. With this alternative pellet, theycould save 50.8% food procurement cost or equal Rp 6,097/kg.Kata kunci: rancang bangun, mesin granul, pakan ikan dan udang

Abstract

The purpose of this study was (1) Know the process of applying for K3 management system development projects Fly Over Flower Market Surabaya, (2) Getting the elements associated with OHSAS 18001:2007. From the analysis it was found that (1) monitoring and evaluation process of the construction SMK3 Fly Over Flower Market, is only intended to measure the level of implementation of SMK3 in fulfilling the terms of the security, safety and health at the site of construction activities carried out to the service user (PIU ), KDP, and the service provider. By adjusting the results of the monitoring and evaluation SMK3 into the element K3 OHSAS 18001:2007 Management, implementation SMK3 more profitable. The advantage is that its elements can be used to specify the K3 policy, planning, program objectives and K3. (2) Through Gap Analysis calculations using the Radar Chart, obtained K3 Management OHSAS 18001:2007 elements associated with the results of the monitoring and evaluation is an element SMK3 K3 Policy (clause 4.2) with a value of 94.00%, Planning (clause 4.3) with values 96.30%, Implementation and Operation (clause 4.4) with a value of 96.30%, Inspection and Repair (clause 4.5) with a value of 93.34% and Management Review (clause 4.6) with a value of 93.33%.
