 Abstract
 Purple leaves (Graptophyllum pictum L griff) is a plant that has many benefits. People generally use purple leaves plants as herbal plants. The part of this plant that is often used is the leaves. Various kinds of processed purple leaf products have been developed, one of which is a purple leaf herbal drink that can be brewed like tea. In the manufacture of these products, a purple leaves drying process is required, namely the process of reducing the moisture content of the wet material to a certain moisture content value. The use of a dryer is able to speed up the drying process, not dependent to the weather, quality guarantee, more hygienic product, homogenic result, and it does not require a large area. In this study, a rack-type flash dryer was used with LPG fuel and added a fan to obtain a forced convection effect, in which hot air is circulated evenly by the fan in the drying chamber. The purpose of this study is to determine the effect of temperature distribution in the drying chamber, calculate the efficiency of the drying machine, and determine the final moisture content of the material from the drying process. The conclusion of this study shows that the flash dryer is very efficient in the process of drying purple leaves, the lowest water content is found on shelf 2 (middle part) with an average of 7.47% with a large amount of","PeriodicalId":475972,"journal":{"name":"BETA (Biosistem dan Teknik Pertanian)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135809369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

 Gangguan distribusi air juga kadang-kadang disebabkan oleh adanya sampah dan faktor pemias (penyusutan debit) serta mengabaikan aliran numbak (aliran lurus) dan ngerirun (aliran berbelok). Dengan pemahaman seperti itu maka petani (krama subak) yang lahannya terletak di hilir cendrung mendapatkan kuota air yang kurang dari seharusnya. Penelitian ini bertujuan untuk mengetahui kinerja manajemen distribusi air irigasi sesuai nilai dan kriteria RPM pada subak tradisional dan subak semi teknis. Penelitian ini menggunakan metode deskriptif-kuantitaif yang menjelaskan peristiwa berdasarkan nilai RPM dari 30 bangunan bagi (temuku) pada subak di Kabupaten Gianyar. Hasil penelitian menunjukkan 30% memiliki kinerja distribusi air irigasi yang sangat kurang, 30% dengan kriteria kinerja kurang, 13% dengan kriteria kinerja cukup, dan 27% dengan kriteria kinerja baik. Dari hasil tersebut juga dapat diperoleh dimensi baru dari bangunan bagi pada subak dengan pendekatan formula proporsional yang melibatkan variabel luasan subak yang diberikan air irigasi, luasan subak di hilir, serta koefisien gangguan aliran air sekitar 1,05 sampai 1,1.
 Abstract
 Disturbances in water distribution are also sometimes caused by the presence of rubbish and biasing factors (decreased discharge) also ignoring the flow of numbak (straight flow) and ngerirun (curved flow). With this understanding, farmers (krama subak) whose land is located downstream tend to get less water quota than they should. This research aims to determine the performance of irrigation water distribution management according to RPM values ??and criteria in traditional subak and semi-technical Subak. This research uses a descriptive-quantitative method that explains events based on the RPM values ??of 30 buildings for (temuku) in Subak in Gianyar Regency. The research results showed that 30% had very poor irrigation water distribution performance, 30% had poor performance criteria, 13% had sufficient performance criteria, and 27% had good performance criteria. From these results, it is also possible to obtain a new dimension of the subak building using a proportional formula approach involving variables of the area of ??the subak provided with irrigation water, the area of ??the subak downstream, as well as a water flow disturbance coefficient of around 1.05 to 1.1.","PeriodicalId":475972,"journal":{"name":"BETA (Biosistem dan Teknik Pertanian)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135809572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

 Abstract
 This study aims to determine the effect of the type of container (bamboo basket, plastic basket, and cardboard) on the physical characteristics and quality of tomatoes during the distribution process using ground transportation simulation. This study used a 2 factorial randomized block design (RBD) with 3 repetitions. The results of this study indicate that the maximal physical damage occurred in the bamboo basket container within 5 hours of treatment because the bamboo basket has rough sides and high porosity of 4.078% (physical damage in the form of increased scratches and bruises and decreased hardness). Minimal damage occurred in the cardboard container with a 1-hour treatment because it has a smooth coating of the container and not too high porosity, namely 3.960%. The best container to use in the tomato distribution process using a ground transportation simulation is a cardboard container (having low porosity the cardboard and a smooth container layer) so can be maintained the condition of the tomatoes.","PeriodicalId":475972,"journal":{"name":"BETA (Biosistem dan Teknik Pertanian)","volume":"518 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135683218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

 Irigasi didefinisikan sebagai sarana dalam memanfaatkan sumber daya air. Di Bali, pengelolaan irigasi dilakukan dengan membentuk organisasi bernama subak. Salah satu ciri subak adalah anggotanya memiliki satu sumber air yang sama dan mendapat pembagian air dari sumber tersebut secara adil. Pengaturan diperlukan dalam membagi dan mendistribusi air irigasi, agar jumlah air yang diberikan sesuai kebutuhan tanaman. Tingkat pemberian air irigasi masih belum sesuai di masing-masing subak, sehingga diperlukan evaluasi kinerja irigasi menggunakan analisis RPM. Penelitian ini bertujuan untuk mengetahui sebaran nilai RPM dan strategi distribusi air irigasi pada subak. Analisis RPM dilakukan dengan mengukur debit tersedia, menggunakan pendekatan analisis data kuatitatif, dan dengan menghitung kebutuhan air irigasi menggunakan data rata-rata klimatologi 10 tahun terakhir periode 2012 – 2021 yang diperoleh dari BMKG Wilayah III Denpasar serta data hasil wawancara dengan pekaseh. Hasil analisis menunjukan kinerja irigasi katagori “baik” didominasi oleh subak pada DI Aya dengan sebaran nilai RPM 0,77 – 1,19; sedangkan katagori “sangat kurang” didominasi oleh subak pada DI Gadungan Lambuk dengan sebaran nilai RPM 0,00 – 0,36. Saat musim kemarau, semakin ke hilir menghasilkan kinerja jaringan irigasi “sangat kurang”. Supaya kinerja irigasi selalu dalam katagori “baik”, maka strategi distribusi air irigasi pada subak di DAS Ho dapat dilakukan dengan pergiliran pemberian air irigasi dan perbaikan jaringan irigasi yang bermasalah.
 Abstract
 Irrigation is defined as a means of utilizing water resources. In Bali, irrigation management in agriculture is carried out by forming an organization called Subak. One of the characteristics of subak is that its members have the same water source and receive a fair distribution of water from that source. Regulation is very necessary for dividing and distributing irrigation water so that the amount of water given to the land is in accordance with the needs needed by the plant. However, the level provision of water irrigation is still not appropriate for each subak. Thus, it is necessary to evaluate the performance of irrigation networks using MPR analysis. MPR analysis was carried out by measuring the available debit, using a qualitative data analysis approach, and by calculating irrigation water needed, using the average climatological data for the last ten years, from 2012 - 2021, obtain from BMKG Region III Denpasar and data from interview pekaseh. The results of the analysis show that irrigation performance with the good category is dominated by subak in DI Aya, with a distribution of MPR values of 0,77 – 1,19.

 Penelitian ini dilakukan untuk mengetahui pengaruh penggunaan jenis kemasan yang berbeda terhadap mutu kentang serta mengetahui jenis kemasan manakah yang menghasilkan kualitas kentang yang baik selama penyimpanan suhu dingin. Penelitian ini menggunakan Rancangan Acak Lengkap dengan dua faktor perlakuan yaitu kemasan dan waktu. Parameter yang diamati yaitu nilai susut bobot, tekstur, kadar gula, warna, laju pendinginan, tingkat kesegaran, dan kerusakan bahan. Hasil penelitian menunjukan bahwa kemasan polipropilen merupakan kemasan yang terbaik dengan nilai parameter bobot 0,05%, tekstur 65,7% N, kadar gula 8,50 Brix, warna (L 35,56; a 19,33; b 26,76), kesegaran bahan 10,50% kentang selama penyimpanan suhu dingin. Pengaruh kemasan plastik polipropilen dapat mempertahankan kesegaran kentang sampai hari ke-56 dibandingkan kentang yang dikemas dengan plastik polietilen.
 Abstract
 This study aims to find whether the use of different types of packaging can affect the quality of potatoes and to find out which types of packaging produce good-quality potatoes during cold storage. This study used a completely randomized design with one treatment factor, namely two different types of packaging. Parameters observed were weight loss, texture, sugar content, color, cooling rate, freshness level, and material damage. The results showed that polypropylene packaging was the best with a parameter value of weight loss of 0.05%, texture 65,7d, sugar content of 8.50 Brix, color (L 35.56, a 19.33, b 26.76), freshness level of 10.50? during cold storage. The effect of polypropylene plastic packaging can maintain the freshness of potatoes until the 56th day compared to potatoes packaged with polyethylene plastic.","PeriodicalId":475972,"journal":{"name":"BETA (Biosistem dan Teknik Pertanian)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135255680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
