Abstract

Sampah sudah menjadi persoalan serius bagi masyarakat. Produksi sampah di dunia semakin meningkat, sedangkan laju pengurangan sampah lebih kecil dari pada laju produksinya, hal ini menyebabkan sampah semakin menumpuk. Berbagai upaya pemanfaatan sampah organik dengan teknologi baru telah dilakukan, salah satunya dengan memanfaatkan larva Black Soldier Fly (Hermetia illucens). Tujuan dari penelitian ini untuk menganalisis besar persentase kemampuan larva BSF dalam mereduksi sampah organik sayuran/buah-buahan dan lauk. Penelitian ini dilakukan dengan metode percobaan skala laboratorium. Sampah organik yang digunakan sebagai sampel adalah sampah yang berasal dari sampah makanan khususnya sampah  sayuran/buah-buahan  dan  lauk  dengan  frekuensi  feeding  sekali  dalam  3   hari.   Analisis   data   yang   digunakan   pada  penelitian   ini   yaitu  Rancangan Acak Lengkap (RAL) dengan 2 kali replikasi (pengulangan) dan metode analisis yang digunakan adalah Analysis of Variance (ANOVA). Berdasarkan penelitian ini, persentase terbesar reduksi sampah oleh larva BSF sebesar 74% dan berdasarkan persentase yang diperoleh ditentukan bahwa variasi jenis sampah sayuran/buah-buahan dengan frekuensi feeding sekali dalam 3 hari lebih efektif untuk menghasilkan persentase reduksi sampah yang optimal. Kata kunci: frekuensi feeding, jenis sampah, larva BSF, reduksi sampah organik.  Waste has become a serious problem for the community. Waste production in the world is increasing, while the rate of waste reduction is smaller than the rate of production, this causes waste to accumulate more. Various efforts to use organic waste with new technology have been carried out, one of which is by utilizing the larvae ofxBlack Soldier Fly (Hermetia illucens). The purpose of this study was to analyze the large percentage of BSF larvae' ability in reducing organic waste of vegetables/fruits and side dishes. This research was conducted by laboratory-scale experimental method. Organic waste used as a sample is garbage derived from food waste, especially vegetable / fruit waste and side dishes with feeding frequency once every 3 days. Data analysis used in this study is Complete RandomIzedxDesign (RAL) with 2 times replication (repetition) and the analysis method used is Analysis of Variance (ANOVA). Based on this study, the largest percentage of waste reduction by BSF larvae is 74% and based on the percentage obtained it is determined that variations in the type of vegetable/fruit waste with feeding frequency once in 3 days are more effective to produce an optimal percentage of waste reduction. Keyword: BSF larvae, feeding frequency, reduction of organic waste, types of waste.

Abstract

The use of plastic is increasing as the population increases, while plastic has properties that are difficult to decompose, efforts are needed to reduce plastic waste into other useful products. One alternative that is used is to make plastic waste into a mixture of paving blocks, which is a purpose of this resarch. In this studi using descriptive data analysis. . In this study using descriptive data analysis. In this study, paving blocks were used with a mixture of High Density Polyethylene (HDPE) & Polyethylene Terephthalate(PET) plastic waste and additional used oil as fuel and thinner. To obtain 1 paving block made from plastic waste, it takes 2 kg of plastic with a composition ratio of 1.4 kg HDPE, 0.6 kg PET plastic, and 0.66 L used oil. The rasults of the compresive strength test of the 3 paving blocks obtained an average value of 11.37 MPa, then based on the quality requirements based on SNIi 03-0691-1996 they met the requirements and entered the D quality category for garden and sidewalk purposes.

Abstract

Uneven access to clean water distribution from PDAM Tamiang Layang City causes the people of Gumpa village in the dry season to have difficulty getting clean water. This problem can be solved by designing a water supply system independently. The purpose of this planning is to analyze the need for clean water by projecting total water needs, designing a clean water distribution and transmission system in Gumpa village. Measurement of spring raw water discharge is carried out by the method of volumetric measurement, water is transmitted with the help of centrifugal type pumps. The transmission and distribution of clean water uses a gravitational jetting system, and the pipe used in this planning is the HDPE pipe. Keywords: Raw Water, Broncaptering, Reservoir, Discharge Draining

Abstract

In 2021 PDAM Bersujud Tanah Bumbu in the Batulicin BNA unit recorded a water treatment discharge of 270 L/d, while the maximum daily demand discharge is 206 L/d, meaning that there is still 54 L/d of water that should be used for the development of distribution networks, and also in that year the coverage of clean water distribution services in the Batulcin District was relatively small, namely 39%, this was because many people in the Batulicin sub-district used ground water or drilled wells. continuous use of groundwater is not recommended. Article 34 of Law No. 7 of 2004 titled "Groundwater" indicates that groundwater is one of the water resources whose availability is constrained, whose destruction has significant effects, and whose recovery is challenging. Therefore, it is essential to implement a plan for the creation of a clean water distribution system at BNA Batulicin. According to the village SDGs, planning is done over a nine-year period with an objective of 100% service coverage by 2030. The planning process is separated into two phases: 2021 to 2026 and 2026 to 2030. Population projections are used to calculate water needs using geometry and arithmetic formulas. With a population of 139,709, the findings of calculating BNA Batulicin's water demands in 2030 show that the average water requirement is 328 L/d, the peak hour requirement is 492 L/d, and the maximum daily requirement is 361 L/d. The EPANET 2.0 application is used for hydraulic simulation at the end of pipeline network planning, and the results show that it complies with the water flow technique. Specifically, the pressure parameter of 96% of nodes is worth 10–30 mka and 4% is worth 30–50 mka, while the pressure loss parameter is 40% is 0.01 m/km, 31% is worth 0.01–1 m/km, 15% is worth 1–4 m/km, and 13% is worth 4
