CV. Cihanjuang Inti Teknik is a small or medium-sized business (UKM) engaged in the traditional beverage processing industry. The company is faced with problems of use to optimize the use of work time so that there is no idle work time or overtime working hours. Other problems, so far the procurement of raw materials carried out is also only based on estimates, namely with raw materials made in stock without taking into account quantitative calculations. The goal programming method is used with the aim of analyzing and describing the optimal use of resources in working hours and raw materials from the average production target needed by the company. The calculation of goal programming is supported by using LINDO (Linear Interactive Discrete Optimizer) program to obtain the optimal number of products from working hours and raw materials needed by the company. The results of the study obtained optimal regular working hours in scenarios I, II, III, and IV respectively in the amount of 159.95 hours/month, 174.25 hours/month, 176.26 hours/month and 192.37 hours/month. There was also an increase in the use of raw materials for ginger, coffee, ginseng and pepper in scenario II, raw materials for ginger, white and vanilla sugar in scenario III, raw materials for white sugar, vanilla and cinnamon in scenario IV.

Indonesia has two seasons. These are wet season and dry season; in the dry season, water from rainfall decreases and demand for water as irrigation resources decrease. Soil water is expected to supply irrigation in the agriculture sector. Water quality at Universitas Padjadjaran can be affected by poor water disposal planning and the location of the surrounding industrial estate, animal farms, farm activities and domestic wastewater. Poor water quality can affect the quality and quantity of crops. Melon is commonly not needed much water as a consumptive use but needs water in whole life and usually applied irrigated, especially if growth in the greenhouse. Poorly applied water qualities of the melon can will impact the quality and quantity to decrease. Research on the impact of soil water quality on yield and quality and consumptive use of melon was conducted at the greenhouse located in Universitas Padjadjaran Campus, West Java Province, Indonesia, from July to November 2019. The research method is descriptive analysis, and melon is planted in containers called autopot and fertigation daily applied by control of autopot smart valve. The results show that TSS of soil water were 200.2 mg/al; TDS 300.2 mg/L; EC 0.75 mS/cm; pH 7,0 and turbidity is 4.75 NTU. The quality of melon shows that water 95.19%; Fat 0.88%; ash 0.57%; protein 1.37%; carbohydrate 1.99% vitamin C 6.91% and sweeteners is 9.4 Brix. In conclusion, that soil water meets requirements as resources irrigation to applied melon.

Industri makanan merupakan salah satu sumber penghasil limbah cair. Industri makanan pada penelitian ini berada di tengah kota yang limbahnya berdampak langsung pada masyarakat. Tujuan penelitian ialah melakukan proses pemisahan minyak dan lemak serta membuat sabun cair berbahan dasar minyak dan lemak limbah cair. Metode pertama yang digunakan ialah grease trap dan metode kedua ialah pemurnian dengan degumming dan deodorizing. Penggunaan metode pertama menunjukkan peningkatan dengan karakteristik BOD menjadi 5.371 mg/liter, TSS menjadi 117 mg/liter, minyak dan lemak menjadi 5,0 mg/liter, berkurangnya bau serta pH menjadi 7,44. Selanjutnya, penggunaan metode kedua dengan penambahan 2% bentonit dan 2% zeolit mendapatkan hasil kadar air 0,015%, kadar abu 0,11%, kadar protein 0,45%, kadar lemak 100% dan kadar karbohidrat 0%. Sabun cair dapat dihasilkan dengan penambahan VCO (Virgin Coconut Oil) yang mampu meningkatkan pembusaan. Perbandingan penggunaan bahan utama sebesar 50:50. Hasil analisa mutu SNI 06-2048-1990 adalah alkali bebas 0,0077%, lemak tak tersabunkan 1,9808% dan minyak pelikan negatif telah memenuhi persyaratan. Namun, jumlah asam lemak tidak memenuhi persyaratan dengan nilai sebesar 7,151%. Kadar air sebesar 53,9696% tetapi tidak ada angka spesifik pada SNI untuk parameter ini. Hasil pengujian organoleptik menunjukkan panelis menyukai sabun tersebut dengan nilai rata-rata lebih tinggi dibandingkan sabun pembanding dengan interpretasi baik.Kata kunci: Limbah cair, minyak dan lemak, sabun cair
