Abstract

Liquid smoke is the product of the condensation of burning organic matter by the pyrolysis process. Grade 1 liquid smoke for preservatives is processed through a purification stage with multilevel distillation which takes a long time. This study aims to obtain the quality of coconut shell liquid smoke grade 1 based on SNI 8985:2021. The liquid smoke purification process uses the dehydration method with bamboo betung activated charcoal as an adsorbent with variations in sizes of 40 mesh, 60 mesh, 80 mesh, and 100 mesh. The parameters observed were water content, ash content, SEM (Scanning Electron Microscopy), acidity (pH), and GC-MS (Gas Chromotography-Mass Spectroscopy). The results showed that the 40 mesh treatment resulted in a moisture content of 4.38%, 2.70% ash content, pH 3.3, and a purification time of 87 minutes. The 60 mesh treatment resulted in a moisture content of 5.78%, ash content of 3.39%, pH of 3.2, and a purification time of 90 minutes. Treatment of 80 mesh resulted in 5.95% moisture content, ash content of 4.14%, pH of 3.1, and a purification time of 93 minutes. The 100 mesh treatment resulted in a moisture content of 6.75%, ash content of 7.50%, pH 3, and a purification time of 100 minutes. The resulting grade 1 liquid smoke contains phenol compounds of 1.94% - 5.14%, creosol compounds of 5.84% - 15.56%, and acid compounds of 0.11% - 3.47%. The 100 mesh adsorbent is recommended as a food preservative with the characteristics of a clear color, odorless, pH value of 3.0, phenolic compounds of 5.14%, acidic compounds of 3.27%, and creosol 15.56%.

Abstract

Indonesia has several water sources under community settlements, making difficult water distribution. Thesimple technology used to raise water from a lower place to a higher one is a hydraulic ram pump. Thisstudy aims to obtain the inlet diameter pipe concerning the height of the place and the time to raise thewater. The research method uses a functional design and tool performance test with three inlet pipesmeasuring 2.54 cm, 3.175 cm, and 3.81 cm. the inlet heights are 80 cm, 110 cm, and 140 cm, respectively.The results showed that inlet diameter affected the height of the place and the time to raise the water. Thebest inlet pipe measuring 2.54 cm can produce water discharge with inlet heights of 80 cm, 110 cm, and 140 cm. The ratio of the inlet and outlet discharge ratio is 5:1, while the maximum pumping height ratio is 1:5. The water discharge produced in Subak Bunut is 0.00831 liter/second with a distance of 20 meters and a maximum height of 470 cm.

Abstract

Wiwanda Agrow is one of the strawberry agritourism in Bali that has not used the assessment theory of supply chain management to assess its performance. This study aims to analyze the performance of Wiwanda Agrow's supply chain using the SCOR theory with the AHP approach. SCOR is a supply chain reference unit that integrates elements in management, namely business process reengineering, benchmarking, and measurement processes. The AHP method is a weighting process for each criterion, attribute, and sub-criteria. The results of distributing SCOR-based construct questionnaires obtained 5 core processes or criteria, 10 attributes, and 22 key performance indicators for further analysis using the AHP method. The results of data processing using expert choice software. The lowest value in the return process is found in the key indicator performance (RRE 1) level of consumer complaint handling with a value of 0.003 and the highest performance value is found in the plan criteria with key indicator performance (PRE 1) planning of strawberry seedlings with a value of 0.252. The overall performance assessment result of Wiwanda Agrow was 89.3. This value is categorized as "good" performance based on the normalization theory.

Abstract

Improving the quality of liquid smoke is carried out by purification (adsorption and distillation) usingvariations in column length and type of adsorbent. This study aims to determine the effect of the type ofadsorbent (activated charcoal, silica gel, and zeolite) and the length of the column (5 cm, column 10 cm,and column 15 cm) on the duration required to purify liquid smoke. Parameters analyzed consisted of aroma, color, long purification time, and compound content. The liquid smoke compound content test by the GC-MS test. The results showed that the column with a length of 5 cm and the type of silica gel adsorbent was the fastest purification time at 138 minutes. The length column of 15 cm and the type of activated charcoal adsorbent were the longest purification time at 207 minutes. The results of the GC-MS test show that activated charcoal adsorbent is the best liquid smoke with specifications of a whitish yellow color and clear, not strong aroma, and a phenolic compound content of 12.88% in accordance with the quality standard of liquid smoke according to FAO 2001 which is allowed for use as a food preservative.
