Waste Analysis Using Lean Manufacturing in the Film Production Process Step 2 Ulama

Abstract - The film Footsteps 2 Ulama produced by LSBO Muhammadiyah in collaboration with Ponpes Tebuireng Jombang is a semi-documentary film that tells the journey of Kyai Ahmad Dahlan and Kyai Hasyim Asy'ari. At the time of the production of the film Jejak step 2 Ulama in its implementation there were several problems such as delayed production schedules, human resources that were not as needed, scheduling errors, and also production defects in several scenes so that they had to be re-take or it could be said to be re-production to get maximum results, where these problems tend to result in waste or waste. Therefore, a study was conducted to analyze what kind of waste occurs and the most dominant using a lean approach. Based on the results of the study, it was found that waste waiting is the most dominant waste with a weight of 27.11%, then followed by waste over production and excess processing with the same weight of 20.33%, waste defect 13.55%, waste transportation 11.86%, motion 5.08% and inventory 1.69%. From the mapping using process activity mapping, a total of 32 types of activities were obtained, of which 12 were value added activities with a percentage of 50.36%, then 9 of them were necessary non-value added activities with a percentage of 13.13%, and 11 activities included in the non-value category. added with a percentage of 26.49%

Penataan Streetscape Penggal Jalan Lawu Di Karanganyar Sebagai Kawasan Shopping Street Yang Rekreatif

Berbelanja ataupun membeli barang-barang kebutuhan sehari-hari merupakan bagian dari kegiatan sehari-hari masyarakat, kebutuhan tersebut dapat diperoleh dari warung, toko, dan pasar tradisional ataupun pusat perbelanjaan yang ada.

Perilaku masyarakat yang semakin maju dan berkembang ini menimbulkan keinginan masyarakat akan suatu fasilitas tempat perbelanjaan yang lengkap, baik, aman dan nyaman. Hal ini yang mendorong perlunya penataan kembali penggal jalan Lawu di Karanganyar agar tercipta sebuah sistem yang baik untuk meningkatkan kualitas jalan Lawu di Karanganyar, yang nantinya akan dirancang sebagai kawasan shopping street. Dimana kegiatan pada kawasan perbelanjaan tidak hanya sekedar untuk berbelanja, akan tetapi juga bisa untuk rekreasi, dan mencari hiburan

PRARANCANGAN PABRIK KARBON AKTIF DARI BAGGASE FLY ASH (BFA) DENGAN AKTIFASI KIMIA MENGGUNAKAN KOH KAPASITAS 2.500 TON/ TAHUN

Activated carbon is a compound which widely used by companies or factories, such as water treatment, gas purification, sugar industry, waste water treatment. In the world of industry, activated carbon is very needed because it can adsorb the smell, color, gas, and metals. Activated carbon industry have large opportunities to developed, given the need of activated carbon which is increasing every year. The plant is planned to operate for 330 days / year with a production capacity of 2,500 tons activated carbon / year. The main raw material required is baggase fly ash as much as 23486.98 tons / year and as much potassium hydroxide 50% 4132.82 tons / year. The method that used to activating carbon is chemical activation with potassium hydroxide as the activating agent. Stages of chemical activation process is as follows: (i) impregnation (soaking) BFA with 50% KOH solution in the mixing tank (M-02), (ii) activation in a rotary kiln (RK) at a temperature of 600-800 ° C, (iii) KOH washing with water in a stirred tank (M-03), (iv) purification activated carbon products through a process of drying and screening. As a supporting facility, utility unit cooling water supply needs as much as 41184 tons / year, as many as 305.4 kVA electricity, compressed air as much as 15,840 m3/yr, and steam as 60683.75 tons / year. This plant will be built in Tangerang, West Java, with consideration of raw material oriented. Tangerang region close to the sugar industry which produces baggase fly ash, and close to the port that facilitate the procurement of raw material potassium hydroxide which was imported from China as well as the marketing of activated carbon products. Plant location close to the river Cisadane as source of water for utility units. Calculation of economic evaluation results of fixed capital required amounted to $7,898,908.38 + Rp26.638.763.849, 27, and working capital of$ 2,637,457.09 + Rp13.867.914.525, 02. At 100% production capacity, obtained ROI before tax amounted to 36.77%, ROI after tax of 18.38%. POT before tax of 2.03 years, POT after tax amounted to 3.37 years with a BEP of 40.86%, SDP was 18.94%, and 25.4% DCFRR. Based on consideration of the evaluation results, the activated carbon plant with a capacity of 2,500 tons / year is worth to be studied further
